  • @999miki you mean 1500hp at the crank and 800 at the wheels right?

  • what bov?

  • damn that thing is insane

  • Yeah abit out of place but it was in reply to "XxgofalldownXx" comments earlier!

    They did use the 1500HP for qualifying too & yeah about 800-900+ for race!

    Cool stuff!

    But not as cool as a 20b rx7! :D

  • Why did you put there this point?? We know that turbo F1 in 80s had 1,5L engine with boost more than 50psi and max power was around 15000rpm, still 1500HP was on dyno not in race, in race it was around 800HP

  • The fact is im right!

    Williams 1.3L made 1500HP!!!

  • lol...check your facts
