After completing our first GT-R on E85 tuning about a month ago we were very curious to see what the effects of E85 would have on a stock turbo GT-R. It's easy to assume the gains are significant when looking at the results of a GT-R with turbo upgrades. However, would this change in fuel really have that great of an effect on a stock turbo GT-R? We needed a test car to try this out on. The test car for this project was my very own 2009 GTR. It's a big sacrifice, but someone's got to do it :lmfao: We previously made 491 whp on 93 octane on our heartbreaker Dyno Dynamics dyno. For those of you not familiar with our dyno, a stock GTR usually baselines around 380-390 whp. We were blown away by the results. We were able to make 525 whp and 578 wtq at 20 psi boost. This was about 35 whp gain and 85 wtq gain with no added modifications, just switching from 93 octane to E85. It's safe to say the turbo's are maxed out and are just blowing hot air up top. The power gains were significant down low, but power dropped off up top as the turbo's had nothing left to give. A set of intakes, IC's and IC piping is in the near future for this GT-R, but we don't expect much more power out of her until the turbo's are upgraded. Pictures and Dyno graph's are posted below. We're happy to report another successful project here at Forged Performance :cheers:

I still want more Already planning the next stage.

Amazingly enough there is absolutely no wheel spin. Gotta love AWD.

no wheel spin ftw.

wish i didnt have any.

congrats!

incredible! I wonder how long that engine/tranny can hold onto that type of power. Will the other components last with e85's corrosiveness?

There are GT-R's making 650-700whp and 600wtq still holding strong. At the end of the day this is just a basic bolt on GT-R with a fuel change. The engine/tranny will hold up just fine for a very long time. As far as the E85 is concerned the other components will hold up just fine to the corrosiveness. All newer cars are built to withstand ethanol due to the 10-15% ethanol used in most gasoline's these days.
