I want to build a bad *** 350 and drop it in my car and i'm starting with a bare block. I saw the mini-ram on www.tpis.com and the fuel rail that goes with it and wanted to know how sick it was. it sounds like it freakin rocks! does anyone have any experience with this setup? i'd love to know cuz the whole setup is like $1200 and i dont wanna drop that much if i can get the same results or close to it just by porting the stock intake components i already have.

 

miniram is wellll known. search for it. VERY expensive i dont think i'd spend that money unless i got the 1206 ported version, and AFR 210-220 heads and was building a very hot 383-400+ inch motor that wanted to rev over 6500 rpms

stock TPI stuff wont come close, ported or siamesed. Only thing cheaper is a converted LT1 manifold and Holley Stealth ram. LT1 is pretty much the same as the Miniram, and the HSR is only alittle off on performance. 550 dollar HSR vs 1200 dollar miniram for most builds, i'll take the HSR any day of the week

 

 

ok i looked up the holley stealth ram....
System Includes:
Upper and lower intake manifolds
58mm billet throttle body
Bright clear anodized aluminum fuel rails
Fuel injectors
Fuel pressure regulator
255 LPH fuel pump and fuel filters
Commander 950TM ECU
All wiring harnesses
Software and communications cable
TPS, MAP, coolant, air temperature and oxygen sensors
Detailed installation and tuning manuals

this setup is $2387.99!!!!!! i see that u get the 24# injectors fuel pump and filter 58mm throttle body wiring harness and software, but thats a difference of $1100!!!! is that difference about the same price i would pay for the mini-ram and get those things seperate? plus, what are the power gain specs on it? the mini-ram says from 75 - 125 hp gains depending on engine mods! what about the HSR?

 

no, you only need the intake manifold and fuel rails, its 550 bucks from summit. then about 100 bucks for custom fuel line to hook it up to TPI stuff.

everything else works, TPI throttle body and injectors, all the sensors too, except EGR

 

hey i looked and didnt see anything like that for $500. i saw the holley stealth rams but they were all like $3000 too! do u have a part number for what u r talking about?

 

WND-7540 for the regular manifold and rails for 310 bucks

fuel rail kit with adjustable regulator 229 bucks
HLY-534-186

 

is all this stuff just bolt on or do u need to all that other stuff like the wiring harness and ecu and the other stuff?

 

With the HSR it's an intake. You will also need the fuel rail kit cause it's specifically for that intake. If you have fuel injection, you use your ECU, wiring, injectors and sensors. If you don't have EFI then you need to buy the expensive kit with the wiring, ECU, injectors and sensors. Keep in mind you will need a good tune to benefit the intake and to also lose the EGR system. And if your car uses the 9th injector, you'll need a bin from a 89. I'd stay clear of the 58mm TB if you're gonna be under 400ci. 52mm is perfect. 22-24lb injectors will work as well.

I installed the Miniram on my car before the HSR was introduced. With just the intake and 52mm TB, I dropped almost a full second off my ET! The HSR is a close setup so expect at least 3/4 of a second. Crazy huh?

 

Well as u may have noticed I dint really know alot about cars. But I just recently read a thread on here that was talking about a vortec intake with vortec heads. Is this possible and if so would this go along with the hsr intake system. Thanks again

 

There are a few intake manifolds that will work with Vortec heads.

• Holley Stealth Ram
• GM Ram Jet 350
• Vortec TPI

I'm running a Vortec TPI manifold in my vehicle now. If you don't know what to look for (bolt pattern and location), you would never know. The Vortec TPI intake is simply the lower portion that bolts to the heads. The intake ports on the Vortec heads extend higher/taller than early heads. All TPI runners will bolt to the Vortec TPI intake. And since the runners do, all TPI plenums can be used with the Vortec TPI intake.



Vortec TPI is a nice intake manifold, but still runs out of air in the upper RPMs. I used to run the Ram Jet 350 intake manifold (below). A better choice for all around peformance when compared to the Vortec TPI system.

 

so since i dont know how to build engines this is the setup that i am gonna try to get. Please let me know if this will work or if this is all i need to make this work. i am gonna get the Wieland vortec intake manifold from summit prt #7542, then the GM perfomance vortec cylnder heads prt #12558060, then the holley efi fuel rails prt# 534-186.
please let me know if i am missing something to make this work or if the vortec setup is really worth it or if there is something better and cheaper out there. since i dont really know alot besides just doin maintenence on my car amy help will be appreaciated.

 

On the TPIS wesite the example of a built 350 using a 52mm TB and their ZZ-9 roller cam with the Mini Ram produces 450 HP and 430 Ft/LB. I to am considering this intake since I already have their TB and cam. I chose to go with Trick Flow's 195's instead of the AFR's and put them on a ZZ4 short block. Are you of the opinion I will be disappointed if I opot for the Mini Ram?

 

Bear in mind the MR is a top end intake that likes heads and cam to perform at it's best which then need gears and stall changes.You appear to have the lot to make good combo.

I still would not overlook the cheaper HSR.
Comes a very close 2nd especially for street use especially the bottom end performance

Is the HSR even available anymore? I know that they sell the whole kit, but what about just the intake?

 

Intake $320
http://www.summitracing.com/parts/WND-7540/
Fuel rails $185 -$240
http://www.summitracing.com/parts/HLY-534-185/
http://www.summitracing.com/parts/HLY-534-186/

Often for sale in 3rd Gen Parts

 

Will WND-7540 work with my 91 Z? It shows up to 1986

 

I believe they come with the center 2 intake bolts holes elongated to fit both head bolt angles; if not you can just file them out to suit your later heads with the 72 degrees angle

 

Thanks guys for all the input. I appreciate it!

 

Hey man how did you set up the 8 coils????

 

Click on the link in my signature.

 

was that coil per cylinder idea worth the time and money

 

I didn't think the HSR fit under the stock hood without some minor modification. I'd prefer the TPIS Mini-Ram myself, but it is much more expensive as others have said.

 

i am building a 383 with tpis cam, throttle body, heads, and miniram. when i get it all done i will post my results. But i no that the mini ram is a beast. why do you think gm went from the tuned port setup to the miniram. The tpi produces great torque down low but not enough horses to satisfy the needy, so that is why the 17inch long port were switched to the lt1's 6 inch, the mini ram is a 4inch intake draw whiich will level the torque and horses so it is worth it but so is cubic inches you could take the 1200 and make i a 383 and be puttin down some great numbers then later down the road throw the mini ram on and be punched with a gain of 50-100 horses. i dont see 75-150 from just intake swap , i could see a happy 30-45 but other then that is is kinda pushing it.

 

To help you out read this article.

does the holley stealth ram clear the stock formula buldge style hood?

 

For those too lazy to read, I'll sum it up: Miniram wins by 4 hp, Holley Stealth Ram in second place (4 hp less than Miniram). Worst? Stock intake. Also a cam upgrade is recommended.

Outcome? 105 more horses than stock (with the Miniram, 101 more horses with HSR) and practically the same torque PEAK (-30 tq)
Cheers

 

how is any of those setups with the air filter connected right to the throttle body supposed to be beneficial in any way its just sucking heated air in in that location isnt it?

 

Convenience. The engine still makes plenty of power. Obviously there are gains with a cold air intake, but it's an exaggeration to suggest that the air filter on the throttle body is not beneficial in any way.

You got it.

 

would i gain anything by connecting a cone filter to the throttle body on my stock tpi setup?

 

No, you will not gain anything by pulling warm air from directly in front of the radiator.

 

Anytime you can get more air even warm air it's better. Cool air is better.

 

it says it will only fit 350 engines up to 86 i have a 87 iroc would it fit on that

 

Late cast iron heads have the 2 center bolts hole at a different angle
If you get one that doesn't already have the elongated holes to fit both early / late style heads you can just file the four holes out to suit and use a washer under the bolt head for clamping

 

Hey vetteoz how are ya?

FWIW, I have a mini ram 1206 port that supports a SBC 427. VO i correct when he says it is a higher RPM solution. Nothing wrong with that, that's where power is made.

 

I re-drilled the vortec heads for older 12 bolt pattern and used the Miniram III, and it all fits up just fine.

 

If you buy just a k&n air filter the cone one that bolts right on to the throttle body it sets off the service engine light, it runs the engine to lean. With mine the MAF gets all ****ed up if you disconnect it and just run the cone filter

 

it would on a maf setup, but not a speed density

 

How did you expect the computer to measure the air flow after you removed the
AIRFLOW METER?

 

I know with the HSR on the Dyno removal of the airfilter trashed airlow and dropped power. I went with a smaller HyD Flat tappet cam on my 383 then the ZZ-9 with Pro1s and it came off the Dyno at 450hp 465tq. When dropped down to idle it sat at 750 RPM and sounded nice.

 

I noticed you have the efi connections ls1 conversion. Whats your opinion of the system? Is it worth the cost? I'm rebuilding my 383 and considering the system.
Thx,
Tom

 

Is that on a stock engine?
