Sp a good friend owns a GTR 650R - sold as 650bhp when run on most gressive map on 102 octane fuel.
This is essentially a "Full bolt on" conversion for the GTR - the turbos are original but everything else is upgraded including the injectors.
I finally managed to get it on my Dyno for some power figures :lol:
We ran the car in different maps, apart from the most aggressive as we were on pump fuel. It made 586bhp peak. Boost peaks at 1.2 bar and drops to 1.1 at 7000rpm.
I've compared it to my own 997.1 The 997 is standard apart from gutted pre cats and GT2/,2 coolers. Interestingly the power figures on the dyno were identical between .1 and .2 coolers. It's only when you are on sustained throttle that the .2 coolers show a gain in power. The 997 is currently running pretty much a identical boost profile to the GTR.
You can see the GTR makes higher peak numbers, which is most likely down to having a slightly larger turbo. I will be interested to see what figures the 997 pulls with a free flowing exhaust.
An important note is that if the GTR is driven hard, e.g. aftere 2 laps of the Nurburing, it is over heating, with engine, gearbox and clutch temps in the red. The 997 on the other hand barely raises an eyebrow, with oil temp staying below 100C. The 997 could be tuned for more boost - but this would only make more power for short periods and no good for Vmax runs.
