I was looking through Accels adobe acro catalogue - I really like the Superram, and I plan on getting it in the future to make some serious performance for the 90 IrocZ28 - but then I saw the Streetram - im curious, is it cheaper (catalogue had no prices) providing less power than Superram but pretty good numbers nonetheless?

The chart they had up was increases over a stock LG4, which is certainly not the power maker TPIL98's are. So anyone?

 

I wanna keep this up top till at least one guy bites, cmon =(

yet noones got anything to say about my question? Im going to eat dinner.

 

Isn't the streetram just a long tube runner TPI like our stock TPI's? I think it's the same thing as a stock TPI with slightly larger runners and a better manifold and a 1000cfm throttle body. Save your money for the SuperRam.

 

I figured. I thought there was something else that set it apart from our OEM TPI other than larger runners and TB etc

 

I have a similar decision to make. I found a ported Accel/Lingenfelter kit (intake, runners, and plenum) for cheap. I want to get it, but I also want to get the SuperRam some day when I do a full rebuild. Could someone give me a basic breakdown on the advantages and disadvantages of each. Thank you very much.

 

I think Buckeye is right. the Streetram is just Accels base, large tube runners, and ported plenum. I don't think they sell these three items as a kit however. the streetram is a complete stand alone f.i. system and runs over 3 grand. If you like that setup you'd most likely have to by the stuff separate.
The large tube runner setup will build peak torque in mid range like the stock tpi does and breathe better up high, say to 5500. The SuperRam also makes excellent mid range (maybe slightly less than the large tube runners) but builds much better high end hp and has more rpm potential.

 

And the Superram - Bout 700 for the pleum and runners, and then bout 400 for the base manifold. That runs to bout 1100.
The full blown kit is something like 3000, but am I correct in thinking us L98 TPI guys can just do the 1100 dollars worth of stuff and plop in right on?

Question in short form: Can I with a 1990 Iroc-Z bone stock buy the Base, Plenum, and Runners from Accel and have a supperam? Nothing else needed?

 

ahem

 

You can buy just the intake and it will work. The extra dough is for the DFI, injectors, rails etc.

 

The Super Ram plenum & runner kit will bolt to any TPI base including stock, but to get the most benefit use Accel's base. I had the whole setup & had it on an Edelbrock base & later on an Accel base, all with the stock GM sensors & wiring.

 

Not to be repetitive, but I'm gonna map it out in one reply.

The $3000 SuperRam kit is for someone who does not have a TPI car at all and wants to make it a TPI car. It gives the TPI wiring harness, fuel rails, injectors, computer, throttle body, SuperRam base, plenum and runners.

For someone that already has a TPI car, they do not need all of that. Like someone said earlier, you get the base for about $400 and then plenum and runners for $700 adn your total is $1100. You could get a throttle body too, but for a stock engine, you do not want to bog it down with air, so the stock TB will work. With the stock TB, the stock amount of air will be going into the SuperRam components, but the SuperRam components will utilize that air better than the stock TPI unit. It will produce a flatter torque curve and will produce better HP with better rev potential.

Again, most of this stuff is repeated, but there it is all in one reply.

I really want to switch (eventually) to SuperRam plenum and runners over the SLP runners and stock ported plenum. I do belive it will maximize the potential of the air that the stock TB lets in.

 

Thank you! That is all I wanted to hear =D.
I was getting worried b/c someone implied on LV-Fbody forums that the setup costs 3K... and i was like - wait wait I thought it was only bout 1200 bucks.

 

You might want to look around for a used setup. Could save alot of money.

 

This is an option I have considered of course. Since I have not the money nor is my car in an adequate state of tune IMO to jump to that it doesn't matter right now. But yeah If I can find a used setup when I'm at that point I'll grab it.
