hey guys i am stuck i can't decide which intake setup to go with. a vortec tpi setup or a stealth ram setup. which one would i see more gain from on a for "right now" stock 350 right now i think it would be cheaper going the stealth ram route but if the vortec setup gives me more power i will gladly spend the extra cash.

Ray87Z

So your looking at Vortec heads/SDPC TPI vs just the HSR with stock heads? The Vortec setup would out power the HSR on the stock heads I would think. You need a cam though to really take advantage of it. Might be pretty close if you're talking about keeping the stock TPI runners on the Vortec setup, and running the stock cam still. Tough call.

Now if you ported the stock heads for the HSR setup and ran a decent cam on both setups, I'm not sure what we'd be looking at... Interesting.

Iroc n roll

You're really comparing apples to oranges. Your comparing a head swap to an intake swap. The head swap will give you the power now but the intake swap will give you the potential for greater power later. I hope this helps.

Mohammed

i was thinking of the same thing, SDPC TPI vs HSR but with TFS 23" heads and the HOTCAM :hail:

Free Bird

iTrader: (1)

The hot cam is weak. Unless your building a car for the best MPG. I prefer to build it for MPH and ET.

If you plan on adding more things later, then go with the HSR and don't look back. How many people do you know going fast on a LTR TPI setup. Anyone who's really moving has already ditched it. Mini Ram or Holley Stealth Ram.

kevinc

Which cam do you prefer for MPH and ET?

Iroc n roll

Depending on where you live (ie and emissions state or not) the biggest cam you can usually get to pass is one with a 230 exhuast duration. My personal favorite (and one I used) was 224/230 duration with something like .525 lift on both sides. That would make pretty good power on Trick Flows with a HSR. I have heard of people getting higher exhaust durations to pass (like the cc306 cam) but it wasn't easy and required both PROM tuning and white gas.

Also Free Bird is right about the TPI LTR setup. If you plan on going fast your going to want to ditch the LTR setup. If you just want 13's and a fun driving car then you won't have to ditch the intake. You can mod away and keep it there. It's a bitch to take off and work with though. Hey guys, I can swap my injectors in 5 minutes

I don't know about the hotcam being weak, Mike runs 11.8s with one, and yea, gas mileage isn't bad either.

EDIT: Sorry, im off my soapbox. Im with everyone else and ditch the LTR setup, its better to have a broad torque curve than a curve that peaks early and nose dives afterwords.

I'm thinkin stealth ram

Iroc n roll

Day late and a dollar short kemosabe..... The answer to his question as well as the supporting arguments are on the table.

CRZYTRN-92Z28

Just agreeing

Mohammed

what about the TPIS ZZ-X cam? I don’t have to worry about emission because we don’t have any here

.050 IN .050 EXH IN EXH LSA

239 239 0.558 0.558 112

Iroc n roll

Personally I wouldn't buy anything from TPIS, they're just too over priced and they're kinda jerks on the phone. You can find a similar cam made by another compnay.

Choosing a cam is not simple. You have to choose a cam to 1) match your heads, 2) make power in a certain power band (ie low-revver vs high revver) 3) pass emissions where it applies. For cam advice make another thread and post your entire setup and what RPMS you want your cam to make your power and you'll get plenty of suggestions. Make sure you tell them emissions doesn't apply to you as well.

Free Bird

iTrader: (1)

He's not running 11.8 b/c of the cam. Look closely. He also has a damn good set of heads and suspention in an auto car which results in lower ET's compared to a stick. His short time is 1.6X. The car is no slouch by any means, but if he put it in a bigger cam he would go faster. And that's ONE guy. I can name a lot of others that are still running 12's and 13's w/ that cam.

But that's just my opinion. And everyone has one.

kevinc

So...how fast are you running? Talking from experience, or reading <i>Car Craft</i> and trying to sound pro?

Iroc n roll

Ok everybody lets get back to some basics here. Rule # 1, a cam does not make you go faster, a tuned setup does. If a car is tuned for the hotcam it is going to go faster with the hotcam. If it is tuned for something bigger (or smaller) it'll go faster with something bigger (or smaller). There really are no "good" or "bad" cams, there are cams that are right and wrong for your setup and powerband, period. So debating whether a cam is "good" or "bad" out of context is basically pointless.

Also, The words "vortech" and "HSR" haven't appeared much lately, I think it's time for a new thread if we are going to go into cam discussion.

Mohammed

agreed :lala:

Free Bird

iTrader: (1)

I don't know anything about anything. I'm just another high 15 sec. TBI car. Afterall, how much you know about cars is measured by ET not IQ right?

Disclaimer: this is all in good fun and non of it is meant to be taken remotely serious. Take what I say just as it is, words on a message board. Nothing more.

mystikkal_69

iTrader: (2)

LOL @ the disclaimer


another vote for stealthram.........

kevinc

Nice disclaimer! Hard truth is a guy who runs 11's talking about how to run 11's has slightly more credibility than the guy nowhere near 11's nitpicking his setup.

The other factor is emission testing...he, like me, has to pass emission testing periodically. Go too bezerk on the cam and you end up with a car that won't pass. The HOT cam passes easily with decent software tuning.

It's a tradeoff. I'm feeling pretty comfy that I could get a well-tuned CC305 cam thru emissions, next time around that's my pick.

Let me chime in here on this old tread, I already went thorugh this once before and decided to get the HSR. I have had it for about 5 months now and I regret it. ya granted I need a better cam, heads, prom tuning and spare money to rebuild my engine when it blows up from revving it to 6K RPMS just to get the most out of it but I am seriously thinking of going to the vortec TPI setup with the hot cam. I drive my car on the street and go to the track once a year. I want a fun all around car and the HSR to me is too agressive. I dont want to spend another $3,000 to go fast. SDPC claims 357 hp from its vortec tpi. thats pretty good for a fun street car. plus I bet I can bring that up to about 370 or so with a few more bolt ons
so thats my .02 cents on the two of them. who wants to buy a complete HSR

BOTTLEDZr28:
Sure do like the looks of your ride
I have the Vortec SLP SDPC setup w/ZZ4 cam Not there yet but with some tuning it will hit the 12's (see sig.) This was first time out at 1400'

Free Bird

iTrader: (1)

Bottled, that is a nice car man. I agree, the HSR is for the more serious street cars. Where I'm at they have civics running 11.80-12.80's on the street. So I needed to stop fooling around and step up. No matter what the cost was. Although an 11 sec. daily driver is not hard to come by nowadays, especially w/ the LS1

BOTTLEDZ28

iTrader: (9)

thanks for the compliments on the car guys. Im really getting excited about switching backover to the tpi. this time with the SDPC setup. I like the fact that they claim it will put out 356hp at 4200RPMS> that is awsome. I can be hapy with that on the street around here. If I can hang with a new LS1 or vette then I have some bragging rights sincemy car is 13 years old I wonder if there is a better cam other then the HOT can to squeeze a little more out of it

Free Bird

iTrader: (1)

Is that 356 to the ground or at the flywheel? If its at the flywheel that's less than 300 to the ground. Whatever makes you happy.

The are cams better than the LT4. Try calling around to the different companies and get there opinions. Pick something that's going to make you happy.

1bad91Z

iTrader: (1)

Dyno Don - You should be in the 12's no problem with your setup. I have a very similar combo to your's. Only I'm running stage III heads and a bigger cam. I've raced several mid to low 12 sec cars and have never lost a race. How deep are you into PROM tuning or who programmed your PROM? Just curious!

Mike (1bad91Z)

grumpyvette

read this, theres really no contest, the holley stealth ram flows 275-300cfm
and can support well over 500hp
the vortec intake, base runner/heads will have a very hard time exceeding 235cfm as a combo and will make much less hp

1bad91Z

iTrader: (1)

there are vortec motors with LTR TPI intakes on this board running faster than that car.

But yes, the Holley SR is a very nice intake! It's just too bad they dont make a Stealth ram base to work with vortec / fastburn / e-tech heads.

grumpyvette

I was only trying to show a few examples , look, heres the flow figures, and things to read,just because theres not many guys that have worked out their engine combos with the HOLLEY STEALTH RAM YET does in no way reflect the VASTLY better POTENTIAL the intakes flow figures show, while hp is not directly equal to air flow , any intake that flows LESS than the cylinder heads at max cam lift and port flow IS WITHOUT ANY DOUBT RESTRICTING POTENTIAL HP/TQ
BOTH THE SUPER RAM AND TPI have had years to work out the combos, the HOLLEY STEALTH RAM is still too new for most guys to have taken advantage of the potential YET!

Now play with the figures in the calculators below, what youll find is that the if your using a 350 size engine as a guide BTW THE INDICATED Torque PEAK IS WHERE THE CYLINDER FILLING EFFICIENCY TENDs TO PEAK due to RUNNER CROSS SECTIONAL AREA,AND THE HP PEAK RANGE IS WHERE THE RUNNERS TEND TO BE MOST EFFECTIVE, DUE TO HARMONICS/INERTIA in THE AIR FLOWING THRU THEM THATS WHY THEY ARE SOMETIMES A FAIRLY WIDE RPM RANGE SPREAD. you can of course raise the tq peak with cam timing and porting and differant header designs but the harmonic range will tend to stay fairly steady in the intake ports, and yes increasing the displacement tends to lower the rpm ranges

the tpi runner length is ideal for peak tq 3427rpm and 2700-4000rpm for peak hp

the super ram is ideal for peak tq at 4032rpm and 3300rpm-4800rpm for peak hp

holleys stealth ram runner length is ideal at 4700 for peak tq and 5618rpm to 6282rpm for peak hp

the mini ram and lt1 intakes are ideal for peak tq at about 5200rpm and 7244rpm to 8101rpm for peak hp

now KEEP FIRMLY IN MIND the engines tend to enter valve float and get close to engine red line by 6300-6700rpm depending on your combo' after running all the available combos, Ive found a HOLLEY STEALTH RAM is CURRENTLY THE BEST CHOICE,ESPECIALLY IF MATCHED TO GOOD CYLINDERHEADS AND THE CORRECT CAM
all Im trying to show here is that it makes no sence at all to try and feed cylinder heads,cams,ETC. with an intake that flows LESS air than THEY do, THE CYLINDER HEADS SHOULD ALWAYS BE ABLE to OBTAIN AT LEAST 100%- 110% of thier POTENTIAL MAX air flow or your RESTRICTING the ENGINES HP

91formula, if u plan on staying with stock heads and bottom end you are better off with vortec setup. you will get the most potential out of the stock heads. however if u are planning on eventually getting better heads and cam and bottom end then i would say get the hsr to make the most potential out of the combination. and if u go with hsr on stock heads you will have lost potential but it can still be drivable so if u dont want to spend the money on vortecs and get the hsr and slap it on and drive it around til u get the heads and cam should be all right. that way u havent wasted your money on the vortecs. all because u eventally plan on goin better heads and cam. does this sound too confusing? im confusing myself haha. later man

BOTTLEDZ28

iTrader: (9)

all those numbers dont mean crap to me. I already have the HSR and to get the most out of it means I will have to spend a few more thousand dollars on parts and dyno runs and proms and that not what I want to do. ya granted the HSR has a LOT of potenial to be a kiler setup but I dont see myself racing on the street that often and even if I did I dont see myself shifting a stock bottom end engine at 6000RPMS. So with that said, that is why I have chosen to go back to the TPI setup. I m sure a 400hp engine can make me happy while cruising around.
and tho the one who ask aobut the 356 hp on the vortec TPI, that IS flywheel HP numbers. Im sure that number can climb quite a bit with tuing and other bolt ons. so with hp numbers around 360-400 and a T56 with 3.73's I think Ill be happy.

grumpyvette

ENGINES ARE A COMBO OF PARTS,ALL PARTS MUST MATCH AS TO RPM RANGE, CAM TIMING,DYNAMIC COMPRESSION RATIO,DISPLACEMENT,VOLUMETRIC EFFICIENCY, GEARING AND AIR FLOW FOR THAT COMBO TO WORK CORRECTLY
a HOLLEY STEALTH RAM is designed for max efficincy in the 4000rpm-6500rpm range, the cams that exactly match that rpm range have at least 220@.050 intake duration and no more than about 245@.050 duration, the rear gearing should be between 3.73-4.11 with a 3000rpm stall and a 10.5-11.5:1 static compression ratio, the heads need to flow above 240@.o50 lift to take FULL advantage of the intakes flow potential, IT hardly the STEALTH RAMS fault if your running the engine in a combo the STEALTH RAMS not DESIGNED FOR if it FAILS to run up to it FULL POTENTIAL!
now you can and will gain some airflow and HP advantage over a stock highly restrictive TPI intake with just the swap to the far LESS RESTRICTIVE STEALTH RAM INTAKE, but YOU WON,T GET THE FULL POTENTIAL unless the other parts match!. HOLLEY GOT 62hp increases with just a swap to a stealth ram in testing on a camaro but ALL of the increse was above 4400rpm, if your shifting at 5000rpm or so, theres no reason to think your spending much time in the correct rpm range so theres absolutely no reason to expect the average hp improvement! theres NOTHING WRONG with the intake! there is something WRONG with the combo/tuning/gearing, if your expecting to realize the intakes full potential!
the STEALTH RAM itself can easily support 450-480 plus hp, out of the box something thats extremely hard for most of the other intakes to do without extensive port work, but expecting a single part , to work correctly, or up to its full potential, when matched to other parts not designed with matching design rpm and air flow is foolish!
if you intend to run the engine combo in the 1500rpm-5000rpm range a super ram or extensively ported TPI is a better match to the engines, but don,t be surprized at all the tailights youll see from guys that do take advantage of the stealth rams potential!

heres a combo that WILL WORK
3000rpm stall
4.11 rear gear
700r4 trans
383 displacement (4.030 bore/3.75" stroke )
5.7 or 6" rods
11:1 cpr
crower #00471 cam
stealth ram/24lb injectors
58mm throttle body
AFR 190ccheads (74cc)
milodon windage screen
7qt baffled oil pan
yes 10:1 will be LESS likely to detonate,YES 10:1 is a better choice if your not willing to run 93 octane gas and possiably a bit of octane booster (LIKE I DO!) but keep in mind that the ENGINE ONLY SEES DYNAMIC COMPRESSION NOT STATIC COMPRESSION
the piston compresses nothing on its way up on the compression stroke UNTILL BOTH VALVES ARE CLOSED, so the cam you pick is the determining factor in the true working compression, with the correct cam and gearing you can easily run 11:1 compression on 93 octane pump gas, the cam listed above works with aluminum heads, if your running the correct ignition advance and fuel/air mix, you will of course need to figure the dynamic compression ratio OF YOUR PERSONAL ENGINE COMBO BEFORE ORDERING/ASSEMBLING THE PARTS, (youll want to stay under about 8.3:1 dynamic with aluminum heads and about 7.9:1 with iron heads)for 93 octane pump gas but a little carefull tuneing and octane booster will allow some leeway
BTW retarding the cam several degrees not only delays the valve closeing and lowers DYNAMIC COMPRESSION, it tends to move the whole tq curve slightly higher in the rpm range, (good to know if your running right on the edge of detonation with the cam installed on the factory index marks)
DD-2000 predicted 500 hp/513 tq
a very similar engine had 450hp/500tq when built on a 350 short block

brian89transam

Dude, grumpyvette, chill the **** out.

STOP TYPING IN FREAKIN CAPS!

I know you have a boner for the stealth ram, but give it a rest.

Did you even read the above post?

Hey Bottledzr28, one thing you could try is a good torque convertor like vigilante or yank. But that's atleast $700. I'm sure PROM burning would help too. Like you said though, that's a bunch of money to spend.

I'd check in to some other people's setups with the vortec TPI. They might be just what you're looking for, but I don't know how you're gonna get more than the advertised 357hp out of them with bolt-ons. Tuning maybe (the PROM tuning that you already dont wanna have to do). But if I remember correctly it was tested with 52mm TB and huge headers. That doesn't mean you still won't have good ETs though.

Iroc n roll

Man, when did this come back from the dead? Umm...does anyone else realize that grumpyvette has basically answered all questions on the topic a few posts ago? Before anyone else posts on the topic I'd re-read his posts a couple of times. All of the important numbers are right there for you, whichever way you choose.

First of all this would prolly work alright at the track, but if your going for high rpm horsepower why stealth ram?? Check out traxions car, THE LT1 SETUP WILL KICK THE **** OUT THE HOLLEY STEALTH RAM ANY DAY OF THE WEEK AND HAS A MUCH BETTER POWER BAND. IF YOURE LOOKING FOR A FAST STREET CAR
THEN THE VORTEC TPI IS GOOD. its alot fun when u can punch it at three grand and light the tires up, good luck doing that with the hsr. the vortec tpi with vortec heads and all the other crud will get you mid 12's and maybe lower with some prom tuning. throw on a 50 shot and your at 11's. TIMES!!-- WHO CARES ABOUT HORSEPOWER ANYWAY??? TIMES ARE WHAT MATTER. if horsepower is all that mattered then why dont we go buy trucks that have around 350 horse?? track times and consitency are where its at. After jeff gordon wins a race they dont go dyno his car. its all about whopin *** and if suspension/gears and driving get you there then all power to you. AND FOR the record HSR is an OK system but is not something id reccomend on the street, who the hell revs to 6500+ rpms just to have fun anyway, not to mention supporting that kind of high rpm power costs alot of money. hope this helps.

La92WS6

Since this has become an intake thread, I have been seriously considering replacing my stock TPI intake with the TPIS Mini Ram. Can anyone give me the pro's and con's of doing this to give me more HP now. My speed density 350 is stock with most bolt ons. I'd like some extra power now, and still be able to put the intake on the 383 I plan on building in the future.

Thanx,

CrazyHawaiian

I think Grumpyvettes post was great. You dont have to agree with him, but you have to agree that he knows his stuff and backs himself up with facts. Times might be what matters most to you, but numbers are what mean the most to me. I know if I build an engine with the right combo of parts (down to researching flow, etc), it will make more power than the engine some guy built with parts he heard were good. Not saying you are that guy, but pointing out that Grumpyvette has alot of usefull info on the specifics of the EFI intakes made for SBC's that can help us build faster engines. My combo is very different from his, but like him I realize the HSR has alot of potential. I'm just trying to figgure out how it will perform above 6500 rpm. I am building my street car for top end speed (high revs on boost, 6 speed) and so far the HSR is the best bet for for that car. Having alot of torque for the 1320 is fun, but racing 60-150 on the freeway shifting close to 8 grand on boost is even more fun. Just an opinion.

smithtc

iTrader: (5)

Could you please elaborate/explain the above statements?

It's my understanding that horsepower comes from torque...and that if you want the best times, then you build for torque in the highest RPM ranges practicable...and gear accordingly.
Have I learned incorrectly?

I'm trying to decide between intakes, particularly the HSR and the Miniram. Grumpyvette seems to advocate the HSR in the 4000-6500rpm range. So, I don't quite understand the above statement.

87WS6

iTrader: (1)

I am not an expert but as I understand it the Miniram has several things going for it.

It is very similar to the LT1 intake in alot of ways.

PROS:
Easy to install.
Hood clearance isn't an issue.
Excellent Flow
Smallest footprint of all the aftermarket intakes.

CONS:
Not emissions legal.
TPIS can be hard to work with. (The company that makes it)

La92WS6

Ya know I have read on here several times that people have had some problems dealing with TPIS. I don't know if it is just me, but I always use them, and have never had any issues. I know their products are a little more expensive than others, but they work, and what they claim is what you get as far as performance goes. I learned the hard way trying to go cheap for the most power, that you get what you pay for. I don't mind paying the extra $$$ as long as I know my **** is right! Anyway, back to the subject. I understand that by putting the miniram on, you lose roughly 30 ft/lbs of torque, but also pick up roughly 70/80 crank hp. Ok, I'll be able to launch the car harder because I'm not spinning as hard, and will have more pulling power on the top, which is where the LT1 and LS1 cars tend to walk away from us. Right now first gear is mine!!! Is this correct? If so, I think my mind is made up. Does anyone actually have the miniram on their car?

Thanx,

Oh yeah, the original question:

How much dyno tuning do yo uthink would be needed with the vortec TPI crate engine setup from SDPC? Im sure it will be a lot less then a HSR, AFR HOT cam combo? Im still trying to sell my HSR. I am going back to the TPI design for the fun light to light torque racing. asking $625 for a complete HSR setup with all fittings and lines


Rippin92RS, we are in the same power boat. Let me know how your progress goes. Im gonna be looking into a different cam besides the hot cam and see if I can get a few more ponies out of that combo. I wonder how much HP loss there would be going form a 1 7/8 headers to 1 3/4 headers.
