Well i really want to put this 91 TPI setup i have onto my car.. but im just not sure on how easy it will be? Just tryin to get some advice on how easy it would be and if it is even worth the time or if i should just stay with a carb. I am in the process of starting my 400 small block, should i put the tpi on it? or should i stay carb.. yeah i know theres a lot of stuff left i need but i thought TPI would be nice.. or maybe even the stealthram setup. Lookin on your guys opinions what you would do. Setup is gonna be 400 SB with my 5 speed, not sure what internal work on the motor im doin yet but just tryin to get advice on my fuel delivery first.
Thanks guys

Tim

TPI isn't enough for a 400. You need to not only swap the parts into your car... but you ened to do the wiring too, and maybe a chip for the engine you have now.

Dont know what your current fuel system is, but you will need a fuel pump capable of sustaining 43psi+ which means your lines need to sustain that aswell and you need a return line.

worth going to stealthram? or should i stay with the easy carb setup

Well, if you want power above 4800 rpm, where TPI starts to weeze out no matter how you change runners and porting etc., then stick with a carb. Not to mention they take less hardware to tune. Wink

What the hell are you talking about... My stealth ram made power past 6k?

And if you can pass emissions w/ carbor don't need to pass emissions, and don't want the extra 2-3mpg.... Stay carb and save many a headache.

Besides, if the TPI is complete, I might know someone who could take it off your hands for the right price...

Gibbs, the HSR is basicly a tunnle ram with a plenum on top, it really starts to come into its own in the upper RPMs, unlike TPI where the intake resonence starts to work against it self. the HSR would be good on a 400, but if you can go carbed, i think it is the way to go, power is probably actualy better with the carb, and it is cheaper... win win situation.

Dont listen to Gibby Tim, he is sharing half his brain with an evil twin (or is he the evil one?).. Confused

Anyways, like Dewey and Paul said, the HSR is great for the upper RPMs, and if you have the coin go that route because it will work on your 400. Smile

hmm... well i dont have to pass emissions ever so.. i was thinkin the stealthram would be nice but i dont feel like the headache and everything i will just stay with a carb, i liked my demon when i had it so ill go ahead and buy another one of those... finally have no motor in my car now.. its kinda nice all these wires i get to cut out... anyway thanks for the advice.. well you know for those who said carb anyway... hehehe anyway ill see if i cant get some pics up on here of work in progress and of my 4th gen also thanks again guys

The Stealth Ram is a fuel injected tunnel ram. With less cubes I made as much torque as a 383 miniram.

Yep, I was wrong.....TPI is the only one of the above that suffers from high rpm power loss.

Dewey, do you really think it's tune port though? Yes it has short runners, but I can see how fluid dynamics would show it using the sound waves like TPI. Since the runners come out of the manifold and open straight up, rather than to pass the sound across....

It IS tuned port, it's just "tuned" for higher rpms. I guarantee that without special fuel mapping, if the same (or similar) fuel curve were used for the idle to redline test, the super-ram would be a total pig under 3000 or so until the tuning came on.

It's the same type of difference between the Performer and Torker for example. Both great intakes, but one is meant for low end and one is meant for upper end. You must still pick the cam, carb, etc to work with the planned use.

Once again, super-ram or TPI, they both have their purposes, and combinations that will optimize them too.

2 pennies for the pot!
