Dynoing my gtp

[BoostedPontiac]

I'll be going to zzp on the 29th to see what kind of power my gtp makes. I'd like to break the nic cam record but I'm not holding my breath. I've done a lot more tuning on it and it's at a "safe" 2.7 pulley, 26* timing, 11.6 Afr. Hopefully it doesn't pop on the dyno.

Go baby go!

Lol. Safe and 26° of timing don't belong in the same sentence.

 

[BoostedPontiac]

That's why it's in quotes lol

I'd like to think I'd be around 350 whp with my current mods.

E85, stage 3 heads, nic, pacesetters, 26* timing, 11.6 Afr, Gen v (2.7 pulley, n*, Lq4 maf, etc

I'm near out flowing my 60# injectors and Lq4 maf. I've seen 113xx on the maf (401 GPS) if that helps with any calculations.

You're definitely making decent power. 60lb injectors max around 500chp on e85, so make sure you don't have any other issues with your fuel system.

you just might want to creep up on that 26º wot. 21 -22 is about all you need really. seems theres no returns running any higher. so ive heard anyways. i cant get mine up there thats for sure lol

I thought that too. I just decided to increase the timing because I couldn't drop lower than a 2.5. I've seen people lose horsepower by going that low so I pulleyd up to the 2.7 and slowly increased timing since I figured it would be better than going out of the efficiency range of the m90 (also adding a lot of heat). Each degree seemed to help a little until I hit 27-28*. At that point I got .5*-1* of kr so I backed it down. All of the tuning was done on a 85* day.

You'll hit 340, maybe 350 to the wheels. I hit 325 with 19 degrees timing e85, s1x, 2.8 setup. And i was getting knock up top (1-2 degrees).

You got a good setup. post vids.
