He did post his mod list. I'll take it at face value, and nitpick...
My car bone stock has 285 HP to the crank. I run a 10.3:1 compression ratio.
My buddy is running 8psi to his VQ35DE. His compression ratio is equivilant to about 14:1 He has about 450 HP at the crank.
You could run alcohol to achieve better horsepower, however, you would have to be dumping in tons of it, and have the car tuned for alcohol. Simply "switching to alcohol for the dyno" wouldn't achieve better HP, unless you spent hours and hours tuning it, just for alcohol use, then tune it back for gasoline use.
Running alcohol on a tune for gasoline would result in a loss of power. Your timing would be way to retarded. For alcohol to get it's best power, you would have to advance the timing a lot, as well as run a totally different heat for your plugs.
If the time and money was spent in tuning for gasoline, why would you switch to alcohol for the dyno...
Changing out the gearing in the differential will increase your dyno numbers. You will have better acceleration, but the difference between 3.35 gears and 3.91 gears won't make 100+ HP.
Another thing to consider is what the drum was set to on the dyno. If it was set to have less drag against the wheels, then it will dyno much higher.
Even with the worst ricer math available, I don't see the HP.
Look at it this way, my car with ricer math... 285 HP+ Intake +10, plenum spacer +20, exhaust +20, chassis bracing +10, would put my car at 345 at the crank. On a dyno 345 would be about 285 at the wheels. My car probably puts down 235 at the wheels, with all the mods I mentioned. That's on a good day. But it is just a guess, since I have never had it dynoed.
So back to the 420 HP at the wheels. Even with terrible ricer math, there is no way that this car is pushing 420 HP. A dyno would have brought that fact to light, since it is measuring the HP at the wheels, not the crank, and ricer math doesn't apply to the dyno.
The only way I see it being 420 at the wheels, is if the drum on the dyno was set for almost no resistance.
I would like to see a dyno sheet for this car. Usually when you have a show car, you have the dyno sheet on display. Usually, when you dyno a car, you at least keep the sheet, since you paid a lot of money for it.
Just as well, reading through an old post you have on here... You claimed to have 420 HP when it had forced induction. I find it very coincidental that the numbers stayed the same, even after the S/C or T/C came off. It doesn't matter that you changed out the internals. Stronger rods and better pistons will not increase HP. They will simply let the engine handle more HP.
Now that I have thoroughly nitpicked the list, I don't buy it.
