Crank HP

H0SS302 · 04-22-2008, 02:16 PM

What does a full bolt on GT 2v put down to the crank. just curious to hear is, never come across that information.

I am curious to this too... I know what I have rear wheel now after the tune, but I wonder what it is before powertrain loss. I don't have pulley's, or heads/cams though... don't know if you're considering those bolt-ons.

i consider bolt ons, ful exhaust, tb/plenum, intake all that bs. heads and cams gets a little involved, so i dont consider those to be easy bolt up, ya know

this is from the Kenne Bell supercharger "divide rear wheel HP by .85 to determine engine (flywheel) HP."

I hope this helps.

H0SS302 · 04-22-2008, 03:31 PM

i got 311(used 265)

black_stang_02 · 04-22-2008, 03:32 PM

bigdrumma22, you should be around 318 flywheel hp and 360 flywheel torque.

H0SS302 · 04-22-2008, 03:33 PM

that makes since tho..i dunno why i didnt just do that in the first place... the .85 is for the 15% drivetrain loss..

Thats a damn good formula.

**thesource** · 04-22-2008, 04:28 PM

It depends on several things like what type of transmission , what diff gear , what tire and the condition of each of these items . I have always been told most stock type autos with tighter convertors use around 14-18% while most 5 and 6 speed designs use about 6-10% . I have heard that Tremec said the T56 in new form uses as little as 2% from their research . I cannot confirm this though .

Nice... and if I go with thesource's 10% rule for my 5 speed I'd be around 301 flywheel hp and 340 flywheel torque which is still nice to me!

atleast i can say im at 300hp lol..... then very quitly under my breath... say... crank hp lol

I just realized another thing too, if this is from Kenne Bell, than I think this would compensate for more parasitic loss due to the supercharger. Just a thought.

That would mean then I have eleventy billion crank hp.

Before or after the blower and NOS?

96greengt · 04-22-2008, 06:34 PM

Blower @ 40psi, NOS @ 200 shot, 18.1:1 c/r, and 118 octane.

black_stang_02 · 04-22-2008, 06:35 PM

dont forget the racing stickers. lol

96greengt · 04-22-2008, 06:36 PM

I don't need stickers.... I have faith.

Faith or not , you will at the very least need a double decker bi plane wing to create enough down force on the rear wheels . Other wise , you are just making noise and spinning the tires .

96greengt · 04-22-2008, 10:04 PM

Guess I better get me some slicks for the front tires to then huh?
