Cayman, this is LYTLdiablo from Supraforums.
Not to take sides, but in all honesty, I don't see you pulling a stock busa in 600whp trim. What I would believe is that your 24psi generates much more than 600whp. Your size turbo should make 600 on 18-21psi I'd suspect without trouble. (assuming your converter is locked up).
There is however a bit of mis-information from Kirk. I'm not trying to start an argument, just correcting information. I would not try and say I know everything about busas, especially modified hayabusas, as I don't own one...and the same should be done on the other side of the fence.
- limited to 500whp on pump gas --> hardly. There are MANY cars with over 600whp on pump, and some with over 700whp. This may not be busa-beating power levels, but obviously it's a large difference from 500.
- need pistons for top end runs --> why? Our pistons have proven themselves up to 980whp, why would we necessarily need to drop in new slugs just to drive our cars fast?
- never find supras running race gas on the street --> There are many supra owners (especially in the Cali/Arizona/Nevada area) that run race gas, or a heavy mix exclusively. If you need to bank on the octane in the tank, you may be in trouble.
Like I said, not looking to cause static, as Nick said on supraforums, I hope our two communities can grow and become friends from these races and others like it in the future. Good to see that no one got butt-hurt over how it happened, who jumped, why this or that...and that everyone had a good time. I look forward to the videos regardless of outcome. Keep up the good work, Nick.
