Question the evo ix fq320 and BHP

so the qwestion is that if this car is 320 bhp what is perspective hp loss all the way to the wheels or what would the whp be? im at like 307whp and 304 tq so is my car going to be as fast as an fq 320?

also i realize bhp is what is at the crank but is the method for calculating this done by a water brake hence the bhp?

He said 307whp so we would assume he's talking about wheel horsepower. For AWD cars you could assume a fudge factor drivetrain loss of 23ish%. So your 307whp would be about 400hp to the crank.

crank hp = whp/.77 (figuring 23% loss)

Edit: Who's faster depends on the driver as well

what i dont understand about the fq400 is that on top gear when they reviewd it they said it had the most unbearable turbo lag ever. did mitsu put in a bigger turbo like a 20g in it?? if so shouldnt it have well over 400 bhp? it seems like it is pretty simple to have an evo with 400bhp with simple bolt ons but i dont see those evo's doing 0-60 in 3.5 seconds or killing lambo's

What seems wrong? It's a fairly direct calculation based off an estimated factor.

>The lag issue came from accelerating in top gear from like 30mph. Try going into fifth or sixth gear at 30mph and go WOT, watch as N/A Honda's pass you

I'm pretty sure BHP = brake horse power. So alil more than whp, but less than flywheel hp.

There is noway you have 23% drivetrain loss, between 8 to 15% tops on our evo:s (Rototest measured 9%)

All the FQ's are rated at the flywheel.

FQ300 305ps @ 6950 / 297lbft @ 4400

FQ320 326ps @ 6700 / 305lbft @ 4300

FQ330 335ps @ 6800 / 315lbft @ 5000

FQ340 345ps @ 6200 / 320lbft @ 4985

FQ400 410ps @ 6700 / 355lbft @ 5400

I dont have the numbers for the FQ360


You can convert HP to PS and NM to lbft etc

The fq400 had a gt3071 or something along those lines. Anything bigger than that and the lag would be too much for a stock car(even though it is a modified production car) Anyone else think the turbo was bigger than that?

I believe you may be mis-informed.
