So far the new combo is up about 11% or so at 35psi (which is lower boost). Was high 500s low 600s with the slicks on (burn out on the dyno so it soaks up the power) last season with the 8.5:1 standard 4202 and with the 10.5:1 GTX-R its at 669whp (35psi). For what its worth the car runs 9.29@150 with 611whp (around 40psi previously) when dyno'd that way.

We'll get some street tires back on and get some proper numbers later. Last year we saw 814 @ 44psi through the auto and around 720whp or so at 35 on street tires. Time didnt allow for all the tire switching as the car is racing in Sacramento tomorrow.

 

Aaron, did you guys tune another HTA3076 aside from mine yet? Luke did manage to get 557hp with the 1250s at 100% after we switched it to speed density. Still more to go!

 

I demand updates Midget!!!

 

Hows the response comared to the standard 4202?

 

I stand corrected. I forgot that you had gone to SD...how much boost?

9.3@153ish at 37psi... up 3mph and 3psi less caompared to the 9.29@149.65 at BOTI. We think the tranny might be going away as this was on the backup tranny and it wasnt feeling like the normal main operations tranny. The car ran mid 152 at 35psi as well but at 9.6 with a fairly soft launch. It was waiting to shift like it didnt have enough line pressure to force the shift.

Jeff says it scares him now. I think that means pretty awesome.

 

I think we had the usual 32psi spike, but it was holding more than the 25psi at 9k than the MAF tune. I think its holding right around 30psi, but its been a while. You should have the graph at the shop.

 

Tell Jeff to man up!

Give Jeff 30 days to get used to it. That turbo is beastly!

 

yeah buddy

 

Looks awesome!

 

Wow, that thing looks purty

 

any other info about the gtx3076r

 

Is that an ATP kit?

 

ATP was just selling the turbo from Garrett. We got it pre-release at that time.
