Hit 460whp!! Dyno Graph . . .

Well I'm still at the shop, so here's the sheet real quick.

 

I hit exactly 460whp on the next run but my rpm readings were off and the torque wasnt right, so I just posted this run right before it.

 

This is at 25psi and 22 degrees total timing. I think I can keep going, but I'm done for the night . . .

 

Not bad for a stock head and cam!

 

VIDEO: I'm in the car with a few buddies helping out.

 

My buddy threw this together real quick.

wow...again very nice! Very impressive indeed w/ stock head and cam.

 

damnit, i hope now my car will finally like a dyno session after I have head gasket swapped out and now can finally tune spark/timing.

Like I said, be patient grasshopper, 10s will come. What turbo config did you end up with? Seems like it shifted the torque curve up a bit.

 

BTW, that AFR is too lean to be safe for pump gas and meth inj, IMO. Now the trick is putting that power to the ground quickly and efficiently.

I am very impressed............honestly I love the sound of boost but went V8 build because I thought these numbers where not reachable with the L28t without big big work. Glad to see some of you guys proving me wrong! Great numbers......we need the vids!

I was thinking the same thing - I'm thinking either higher base fuel pressure or bigger injectors (probably the better option) should be the next change.

 

...but im guessing you already figured that out - I got similar comments when I posted my last dyno pulls, and it so happened that the one that I picked to display was an intermediate run from before I had addressed the issue, but it showed something like 2hp more. :mrgreen:

 

BUT, any way you want to look at it, those are some really impressive numbers, especially considering they were on a stock head and cam! Congrats!

Congratulations Garrett! I believe TimZ hit over 500hp@wheels.

 

 

My dyno graph is below. I did not have my computer with me when this run was made so I was not able to lean it out and make another pass. However, with this tune the car went 10.6@134 (19psi and 125shot of nitrous).

 

Dyno graph is 28psi and no nitrous
