If you look at the dyno runs from GIAC website it shows the GT at 380bhp (459bhp when flashed) and the GT Speed at 457bhp hitting 553bhp when flashed and running on 103octane. Amazing what a bit of gogo juice can do for power...extra 60bhp.

Yep, 91 octane is kinda crappy. Those 22" killed a lot of power. Dyno with bad cooling is not good. Gotta run a big *** fan in front of the vehicle when you dyno. In the long run, a basic Bentley GT only gets about 410 to 420whp. A lot of tuners come to this conclusion. Also, I am going run meth(not the dope)
. Can't find 93 octane out here. Race fuel only at the track. On meth, the way I want her, she will be a pretty fast Bentley
Alot of factors come into when you dyno, elevation, temp, wheel size, but my nephews race a lot of JDM vehicles that are amazingly fast. They will all testify that drivetrain lost is huge in HP.

Great info Jc. I post a thread with mines on dyno also just for baseline. Only at about 395bhp. They said they were getting about 410 to 420 on 93 octane and stock wheels. GIAC is a pretty good company. And yes that 100 octane can jack your HP up. Gotta be careful though. Turbos, intercoolers, and areodynamics might not be able to cool engine down,

I held this back for awhile. Do you know why that that Benz was spitting rocks back at you JC333? He(the MB C63) had a rear diffuser that has a little flat space, almost tray like, to leave tiny little rocks on. When he really quick step that gas in front of you, tiny rocks leave his diffuser and rains on your car. Little rice rocket racers do that alot, so I know.

According to the manual, my 2012 CGT HAS to use 98 RON, or no lower than 95 RON, or bioethanol. Otherwise can cause engine damage says the book

Ken, for "98 RON or no lower than 95 RON" they are talking EUROPEAN ratings standards... so i believe 92 or higher USA graded standard petrol is what they also approve. Agree with others here, when i add a touch of go-go juice to the petrol she DOES respond very positively.
