The two (hp and tq) both have significant meaning, IMO. Then of course as stated above choose the right gearing for what you're running.

Thanks for the compliment Grim, likewise they should read your posts too as there is a bunch of good information you've shared as well (and I've learned from).

Ugh....the old tq vs hp debate. They are just 2 different ways of measuring the same thing. Horsepower = Torque X RPM/5252 end of story. Horsepower is simply a measurement of torque over time. When most people refer to "low end torque" they are really referring to low end horsepower. If an engine makes a ton of tq, say a peak of 530 lb/ft at only 4000rpms, then it is going to make a LOT of power at those lower rpms as well. Let us compare 2 engines:

Engine A: 350 CID, 400rwhp @ 6000rpms 375rwtq @ 4500rpms

Engine B: 383 CID, 400rwhp @ 5200rpms, 410rwtq @ 3500rpms

Obviously both engines make the same peak horsepower, but since engine B has more peak torque and would then make more torque throught it's powerband, then it'll make more AVERAGE horsepower. With the optimal set of gears on each I'll bet the 1/4 mile times would likely be within a few tenths. Gears are important since they keep the engine in the desired RPM range. Engine A would be better off with 3.73/3.90/4.10s and Engine B would make do with some 3.42s.

I was gonna use percentage at first. Dont know why I choose otherwise.


I've read about that "green" legislation. I think you are getting a bit carried away there. There will be tax exemptions on hybrids and stuff. But no talk of a california c.a.r.b. like system. We can still buy any car we choose.

This whole website is by far the most informative website I've found. I've searched for Madmax's posts and read some but I'm no TPI man but there is a lot of general knowledge for any motor. Grim, Xoxide, JT, all the other mods and many regular "Elders" know their stuff. Keep talking and we'll keep listening. I'm sorry I even mentioned the HP, TQ debate . Like iIve said before, if someone builds this motor lets hear your track experience and if possible Rear Wheel numbers.

Actually Madmax also was a moderator of a Tech Board until a few years ago and is one of the very earliest members or "Elder". I just wanted to point out that Madmax has been a long-time proponent of TPI systems and has done a lot of work on this subject.

He is very knowledgable about the system and would be someone some of the newer members should seek info from. I just wanted to make sure people were aware that they knew that Madmax was worth listening to when he is discussing TPI.

You guys are making me misty!!!!!!!!!!! Keep up the great posts.

It would be nice to see somebody build this so we could see how much it put down to the rear wheels. I think it would be a great truck/large car engine.
