Still no dyno sheet for proof.

I still can't belive hes parting out that car after all thats been done

has anyone even beat my 302whp number? NO... so who cares if i dont have a dyno sheet, but 94whp gain is not hard considering the extensive work that was done, and that my 302 was on a stock engine minus 1.6 rockers.

Im going to beat it... as soon as I finish my motor

uh huh you aways have a secret and it always amazes me.  I still wish you werent getting rid of that car though.

Kuntzie were you using the stock DP on that 302 number?  There no way my 3.1 doesnt make 300hp , not going to spend money to get it dynoed tho, rather spend it on making the car faster!

Anybody used the comp .440 lift cam?

I've finished cleaning/dissassembling my tgp engine.
Still have to port the heads and lower intake.
My big turbo will have to wait,as will 350hp-decided to reallocate my $1k turbo budget elsewhere.
I'll be happy north of 250 or around 300 if the turbo will support it.

Glad I decided to rebuild,bearing weren't going to last much longer. Mains had burned in foreign material and bad scratches/grooves.
This week/weekend when I get time my buddy is going to help me with the cam bearings and valve grinding/seats and we're going to throw the longblock together.
He has worked for years at an NHRA supplier/machine shop and knows all the tricks.

I will be dynoing when I'm done also.
Not because I think it is an accurate measure of power,I could honestly care less.
Mainly for tuning,but I don't plan to tune to max output either.

250hp is easy on the stock setup with a small amount of tuning. 300hp is reachable as well...at the crank that is.

Here are some old dyno charts from Josh's(twinturbosedan - RIP :icon_cry:) 5spd + stock TGP setup car. At the time, he had a 5spd chip in the car with very minimal tuning and it was running pig rich. He was running a manual boost controller(will result in instant spool with these small turbos and a huge spike of torque).

Chart w/ A/F(notice how rich it gets/drops off the chart)




After that, Josh had the car tuned again by Kenny(TGPilot) and picked up even more power. It put down ~230whp on a dyno dynamics dyno that is known for reading way lower than others. It would have probably been 250whp+ on a dynojet like he dyno'd on the first time around.

One of flybynite's cars dynod 267 hp to the wheels with bone stock engine and turbo if i remember correctly,  300 to the wheels is cake on a 3.1 with 3 inch DP, 1.6 rocker, turbo upgrade, fuel pump, tune... nothing crazy.

I will have the .440 lift cam,UDP,3" exhaust/no muffler, ported/polished upper,lower,heads,exhaust,water/meth,water/air IC,bored TB and I think that's it.

of course the car is only 2700ish pounds,so 1/4 time will be low anyway :)

And i'll also have nitrous in case I need it,pretty sure I have enough pills for a 10-120hp shot.
Already have a wideband and upgraded fuel pump. (fuel pump pulls to much voltage,fried my relay circuit so it needs rewired.

I'm think I should be good for close to 300hp with all this and of course i'm forgetting some stuff.

only mods i had on the 302whp

5-speed
1.6 rockers
gt2871r
rough tune
29#injectors


engine was still stock other then the rockers, oh ya i had a highflow cat with stock mufflers
