Let's play guess the Bhp

My car is going for mapping on Wednesday  and I thought why not have a little banter guessing the outcome ..

Spec is , Lightened crank , weisco pistons , hks headgasket  , hks cams , tomei rocker stoppers , ported exhaust manifold  , gt2871R , 3 inch turbo back exhaust , 555cc injectors  , Z32 , walbro fuel pump , Apexi air filter in custom airbox , apexi  power fc , apexi boost computer  , pace front mount , alloy radiator,  Fidaza alloy flywheel , CC paddle  clutch , forge pulleys

I'm sure it has more than that if it does I'll update it



Copy and paste and put your name down and your guess
I'll start
1 rob . 381.4bhp

1 rob . 381.4bhp
2 mike74 393bhp

1 rob . 381.4bhp
2 mike74 393bhp
3. Bob 378.1

Doesnt this depend on the boost?

Probably but I don't know what boost that turbo it will make either .

So complete guess .

Depends on size of housing and torque will be down (flywheel) but should boost early and accelerate quicker but might tail off top end. If everything is ok 388.2 drop back to 365 ish

Shit forget that figure should read properly injectors will max out before that in my experience

369bhp and 340ft

Righty, i'll go for 375

371bhp at wheels and tune leaves RR at .
How much get going depend at what injector duty and fuel pressure you happy/capable run .
Other issues could be ignition gremlins at high boost .

Be nice have this one finished and polished ready for the summer .

I'll be more optimistic here and try 405... Mainly because this looks bit like setup I'll be putting in to my car next month     (hopefully)
