nice numbers. Is this 47hp gain in addition to the cobb stage 1 or is this just from the exhaust? Kinda confused about that.

Any 1/4 mile numbers with this setup? You could be a high 10s car there!!!!

It's a 47 hp gain from the baseline stock. The tune still has some work before its perfect. The ecu is still pulling back boost.

Numbers/videos coming soon.

so your saying this car dyno's at 460awhp stock? That is the highest stock dyno I have ever seen. What dyno is being used. Not saying BS but most GTR's dyno from 400 to 430 depending on the dyno stock. About 15-16psi is what I see on my cobb stage 1 car.

stage 1 cobb adds 60-80awhp
mid pipe adds 10-20awhp
exhaust adds maybe 10awhp

the 510whp number with these mods sounds about right but the stock numbers dont??

The dyno is a dynapack. We are working closely with Cobb to develop what will soon become Cobb's official Stage2. I'm 95% sure the baseline is stock; I'll double check for you. Are you familiar with how dynapack dynos calculate hp?

Yes I am very familiar with that type of dyno. Thats good that an official stage 2 is going to be developed, hopefully it will be with all the same parts and sold as a package so there wont be that many more variables when coming up with the hp figure. The stage 2 and up from cobb has had its share of problems in the past with boost cut issues and such. Still as far as i know the best way to achieve more hp is with bolt on parts is to do a custom tune since no 2 cars are alike.

You are right on, the biggest problem at the moment is, boost cutting. The guys are putting alot of time into this to perfect it.

What mods do you have on your GTR besides the Cobb Stage 1?

I have just a mid-pipe and Cobb stage 1

I bet if you go back and load the stage 1 map power will be close to the same and no boost cut. There is something about the stage 2 and higher that the ecu doesnt like

You are 100% right about going to back stage 1; But if no one ever pushed the envelop, we would never get beyond stage 1.

I agree.

Oh ya your gonna probably need boost actuators if you plan on boosting past 17psi. Stock ones seem to be faulty around there and not hold boost

Up to 20psi + u will need injectors. There is already drop in injectors available. But you probably knew all this stuff already
