If you think that 600whp is easily achievable on these cars with a simply bolt on VF kit and 93 octane then you are mistaken. Who knows, maybe it's possible on the EAS dyno and using "STD" correction factors (from what I've seen their dyno reads abnormally high in comparison to others, and I'm not sure why this "STD" trend has caught along to inflate the numbers when its "SAE" that's the most important imho) - but on a realistic dyno using SAE a bolt on VF kit on 93 is not even breaking into the 580whp+ range. I've seen E9X M3's from essentially every kit but Gintani/Gpower both on the dyno and at the track and I can tell you that 600whp in not an easy number to break on a REALISTIC dyno (nor are breaking 10's or trapping over 130mph - the stars need to align); and to do so your going to need at least 8.5psi, meth, lightweight wheels, full catless, race gas, and COLD weather [how is it that all of the E9X record holding M3's at the east coast are barely grazing into the 580whp range and maybe clipping 600 wheel, with meth racegas 18lb wheels and great 50 degree weather; but a lowly 620 kit with simply racegas is putting down over 600whp easily in 85 degree weather in California (meanwhile this VF car got absolutely walked by a bolt on E85 GTR and the very same M3's holding E9X platform records that are dynoing 20whp less are pulling 2-3 cars on bolt on E85 GTR's easily? - Just goes to show something about the dyno being used.] I've learned not to pay attention to this influx of dyno posting on this forum (especially with the debate between blowers and the new AA lineup) because they can be very misleading due to the ease of manipulation and variance (correction factors, weather, etc...) between them - timeslips are a much better indication of what the motor is putting down.
Yeah I agree. Alot of these numbers can not be compared to eachother. Its like comparing apples to oranges. These bolt on kits with no motor builds can't really break 600rwph; its just unrealistic. I could maybe hit 550ish on a good day with 93+ fuel and the VF650 pulley, but not much more. These cars are very well balanced with that type of power for the track. We aren't really setup to mess with even a well tuned GTR with down pipes and I don;t car my car looks cooler IMO . With that being said I am very happy with my car and enjoy the power!
