Actually, torque is meaningless. Torque doesn't win races.

Tell me how much your car weighs, give me a HP curve, and some gear ratios, and I can tell you how fast it'll accelerate.

Torque numbers are nice to throw around, but they serve no useful purpose. The only useful thing torque does for us, is being easy to measure with a dyno in 1:1 gear so we can determine HP from it.

Good parts, but at those prices I consider it a ripoff.
Keep an eye out for a good used set, shouldnt set you back more than $200.

Positive. It's good for arguing, but that's about it. I could also multiply my hp by the radius of the earth, and brag about that number too. An impact wrench makes more torque than your engine, but it sure as hell won't get you down the 1/4 mile faster. Torque doesn't move a car.

hi there central coaster,
thanks for your info mate!
so basically then rpm is what gets you going faster?
so what would torque be useful for then if i may ask please?
i am not questioning you at all about the torque!
thanks

Power is what moves things. The impact wrench I mentioned puts out more torque, but very little power. It will hardly move the car. Yes, torque can be figured by dividing out the engine speed, but it really tells you nothing useful about how fast the car is... You would also need to know the corresponding engine speed (whoops, you just calculated power!)


I'm not talking in touchy feely layman's terms either. These are engineering terms and have very distinct meanings.

The TPI motor just wants to breath, and when it does, it'll make the TQ you are looking for. Horsepower I have learned is not all there is. It is the torque of the TPI engine that makes it shine...
Sorry, the TPI is a POS intake for these cars. You've read too much on here how the TPI is such a tree stump puller, it isn't. It feels like it has just oodles of tq because it falls off so damn fast as the rpms climb.
My miniram car on one of my dyno runs made 340 lbs of tq at 3800. My TPI bigmouth intake made 350 lbs of tq at 3800, same car, different intake. After 4400 rpms the graph just looks silly on how crappy the TPI attempts to keep up compared to the mini. HP was up to the tune of 60.
If you want to waste your money on a aftermarket LTRunner intake setup, go ahead, I did many years ago. I'd never do it again. IT IS THE SUCKIEST OF SUCKY.
Put a stall/gears with a mini or gears with a stick and you have the cat's ***.

Runners, My vote goes to SLP. They are siamesed and can be ported for even greater performance. Check out my website for more info Corvetteplenum.com

Buy what you are going to buy once. SR, or Mini, would be better options.
