DRAKEFAMILY2's link is a good one, too. But in neither post has anywhere near the metal been removed as has been from mine.

For once you got it right. You nit picking, "valve vs drive" train, is the kind of thing YOU interrupt a thread to criticize me for (except *I* don't jump on obvious slips of the tongue or typos) even when you know nothing of the subject. YES! You ARE the pot calling the kettle, black.

I think 22% drivetrain losses is pretty excessive. I have been thinking closer to 15%. But that will depend on auto vs stick as well.
Can't you guys play nice? Or at least go soil your own thread?

Personally, I belive all his books (and Lingerfelter's, Smokey Yunick's, and a few others) should be required reading for someone new to modifying engines
It's like a bible to me. I have read it several times, and I need to get out to the shed, grab it, and read it again. That guy believes in "RAM AIR" heavily. That is what keeps coming to mind when working on the vette. Read it corvette gang!!! Now go get some H.P. outta that CFI. Thank You, You have been a wonderful audience...

I used 15% for manual and 20% for auto, cause they are real easy to do estimates with, and that's all it is.
As far as I am concerned, the driveline will only take so much power to operate. For example, if it takes 20 hp to move the driveline, well, on a 200hp engine, that's 10%, but on a 400hp engine, that's only 5%.
Essentially, its a sliding scale... I cannot beleive that a 1000hp engine is going to be robbed of 15%?

Actually, the power consumed by the engine will go up as horsepower increases, but not proportionally(why do I think I mis-spelled that). This is caused by some of the very things that increase Horsepower, bigger cam lobes and the stiffer springs necessary to run them, higher compression pistons, higher volume oil pump's, etc.....

I have all that "before" stuff, except for the "xram, 454 injectors, edel rpm aluminum 64 cc heads, crame 2040 cam 210/216 @.05, crane roller rockers, ceramic hedman 1 5/8 headers, hooker aero chambers, 7747. Innovative WB". Otherwise our cars are (were) identical.

Say its the crappiest C4 ever made... but when i had the X-ram, larger injectors, cam, roller rockers, cam, headers, dual exhaust, and all that jazz I ate L98's and LTx's for lunch...
