Aright, I finally decided on my setup and it is based on the tried and true Lingenfelter setup. It's gonna be a 355 with a freshened bottom end and forged pistons, AFR 180 heads, LPE 219 cam, and I was planning on going with the Superram, but keep reading about how much of a pain it is. I was wondering how the Stealthram would match this setup? I talked to Jeff M. at Lingenfelter and he said I would be OK with the Stealthram, but the Superram is much more well-suited to the setup. The Stealthram is obviously the easier install of the two and cheaper these days. I am a big fan of low end and midrange. Do you guys think I would still make great power from idle-5800/6000 like the Superram does with the Stealthram? I have seen the Stealthram make some nice torque curves from people's dynos on here, but what do you guys think?

 

I believe that the S/R, and the 219 cam were designed to work together. With the 180 heads, you have a great set up there. If you love torque, the S/R will deliver.

Dont be afraid of the S/R being a pain to install. Its not the easiest to install, but, its not too bad either.

You can do a search, and read the tips to make the S/R install easier. Good Luck.

 

It would depend on how often you take your engine apart.
I take mine apart often.
So I'd end up throwing the SR.
Or not taking it a part so often.
But I'm too cheap to buy a SR.
Just buy a 3.75 stroke crank and a HSR and you'll have both
torque and ease of installation.

 

I have a 383 HSR without a stall and the low end torque is relatively the same as my 383 TBI but I do lack in the low end range now with teh HSR. With a stall I would get it back and its my next mod I do. However, my engine loves it from about 2000 rpms-on.

 

I got a 2600 stall...think itd make up for the Stealthram?

 

i love my hsr on my 383. my 2600 stall was perfect for it. when i get into the higher rpms. get ready for bus lengths.

 

Go with your first choice, the SuperRam. Get the low end and mid-range torque as you wanted. The HSR is much better suited for strokers.

 

Why is that? (post above) I mean im not certain what the top of the high end is on the HSR but im sure its not much past 6500 rpms correct? I know that it produces 10-15 more hp up top at the peak than the superram but the superram increases tq and hp while the HSR drops like 30-40 lb tq....

i mean if you ported a superram i think you could easily get the extended power numbers of the HSR with a peak of about 6300 rpm which is a pretty good power curve from idle to 6300 with constant power

PITA to install and maintain i guess but worth the numbers and legality...well c what kinda numbers i produce when i finally get a hold of a S/R and port & siamese it

 

HSR! but then again i'm biased lol!

 

lol

I'm gonna vote Stealthram too. Might give up some lower end torque but you will have like 6-700$ left in your pocket if u get it instead :-)

later

No doubt, the $$$ is in strong favor for the HSR.

Concerning my comment on the HSR better suited for stroker comes from the simple realization that strokers have the grunt that people like from the cubes and the longer throw of the crank. Also, the HSR will flow whatever the cam/heads allow. So, if you are after improved top end Hp and you have a stroker, the HSR is (my opinion) by far the better choice.

But, if you have a 350 or 355 and like that great bottom end torque for street light to street light racing, then I think that the SuperRam is by far the better choice. And (of course) your cam and heads should match your goal.

 

Low end torque is misleading; how many races have you won at 2500 to 4500 RPM? I have only won one and that is when the other guy redlighted. I have won many races at 5500 to 7800. Low end torque makes you have wheel spin as well. When we used to have wheel spin problems and did all the suspension work we could do we would just put a bigger cam in to negate the wheel spin problem and have more top-end to boot. I have a HSR and my car has 511 ft pnds and over 400 hp at the rear wheels and that is with the fuel pressure dropping from 48 to 35 while it is winding up (currently fixing that problem) but the HSR is about $500.00 and the SR is way higher. Would you pay another 6 or 700 bucks for 20 more HP? My track 1s and the HSR flowed 292 through the entire induction. In my opiniom a mini ram is probably the best but I cant see spending over a thousand dollars so Myron Cottrel can be a millionaire again. Nothing against Myron but just looking at bang for the buck. My four wheel drive has tons of low end torque but I don't race it either I just kill deer and catch fish. Just my country boy common sense.

 

I don't know about all that low end torque going away. The stealram installed on a mild 355 didn't seem to loose all that much power down low. What it did gain up top was crazy, made money back after selling it on ebay compared to the HSR. You are going with AFR 180s they are going to make torque no matter what, stick with the HSR.

 

I agree with what is being said for the most part and the HSR is not a bad setup at all...I too dont like how extremely expensive the SR is its ridiculous...however you DO lose low end torque with the HSR its dyno proven...Everything working together helps win the race and low end tq gets you going and with the proper setup 1000 lb tq will hook up...However keep in mind the HSR IS ILLEGAL does not have emissions capabilities so be prepared for that as well...

id like to get a direct comparison on the FIRST intake vs the HSR they sound very close except the FIRST is around 800 more and furthermore see the numbers a siamesed S/R would produce

im still inbtw my setup choice S/R soo expensive, HSR illegal but a good system, and FIRST hella expensive but great potential

 

Still in the air...all points being said are very good...making it even more difficult. haha Emmissions isn't a big deal for me, so that flaw can be eliminated. There was actually a brand new polished FIRST intake that just sold on eBay for a little over $900.

 

9.8:1 355, 218/228-110 cam, 1.625 shorty headers, single 3" exhaust - 2800 stall, 3.23 gears, 26x11.5 ET Streets.

Box Stock FIRST Injections intake - Best run in 80 degree temps with mild pocket port / clean-up on the G1 heads with 5800/5600 shift point
60ft------ 1/8 ET -----MPH ------ 1/4 ET ----- MPH
1.707 --- 7.992 ----- 85.526 --- 12.599 --- 106.702
_________________

STEALTHRAM - Best run in 80 degree temps and box stock TFS G1 heads with 6400/6200 shift points.
60ft------ 1/8 ET -----MPH ------ 1/4 ET ----- MPH
1.803 --- 8.133 ----- 86.37 ---- 12.673 --- 107.84

Based on the AFR on the dyno with the StealthRam, there was probably .1-.15 ET and 1-1.5 mph left on the table due to the "tune". I feel like there is about the same ET drop potential in a creative timing curve for the FIRST unit, but probably not much if any more MPH in the "tune".

The FIRST is a little tricky at launch even with some suspension upgrades that were not present on the car with the StealthRam,,, but the StealthRam had no traction problems with the stock suspension,,, which can be good or bad,, depending on how you look at it or how much time you spend driving the car.

On a larger engine with more cam, gear, and stall speed, the advantage will definitely shift solidly toward the StealthRam. And,, unlike the FIRST or any other LTR system,,,, the more cam, gear, and stall you throw at it (properly matched),,, the faster you'll go with the StealthRam. It all depends on the car and the compromises you want or may have to make on which is "best".

$1000 new from FIRST Injections is not bad for a LTR system keeping in mind that a 835cfm throttle body included. There is still another $170 or so for a regulator and fuel lines. However, you'll spend around $1070 buying a new Edelbrock base, SLP runners, AFPR, and a 52mm throttle body - then you have to port the runners and plenum to stand a snow ***** chance of coming close to a box stock FIRST unit.

 

SUPER RAM

 

So could i get the holley stealth ram and put a AS&M throttle body on it? also will the LT1 monoblade fit on the stealthram?

 

Lt1 TBs and TPI TBs do not bolt up.Cant remember the differences but did compare them by trying to bolt up. Not compatible, but yet look very similar.

 

Go with the Superram if you want to stay Emissions legal. Thats why I am going with it, if it wasnt that I had to stay emissions legal I would go with the miniram.

 

i like the HSR, but its a little taller than i think it should have been. i put it on a very stock car (headers and exhaust only) and yes i lost some tq down low (my 1/8 times were slower) but i made it back up on the big end (from 1/8 to 1/4 was faster; ET ended up being the same)

 

Yep, that result is very typical,,, slightly less bottom end torque, but increased top end power. I am currently running a ported SR, but if I ever have to take it off again, I may switch to the HSR, having 395 cubes, I am not worried about the bottom end torque lose.

But, I'm thinking again, a well ported SuperRam should flow as much air that your engine can handle, and keep the good bottom end torque.

 

For a street car i love the SuperRam, it pulls strong to 5500 on my 406. Took a lot of porting and tuning to get it there though. Part throttle is equally impressive.

I would love to see what a stealthram would do on a larger cid motor though.

 

too much work to make the stealthram work. i hated it!

 

Um, when you say too much work, what exactly do you mean? I put mine on in just a few hours.
