I have no idea due to every car being a bit different. I couldnt find that information on all the vehicles hence the reason the option doesnt exist. I figure its not that hard to convert by hand for the small few that need crank HP (which in my opinion doesnt matter since it doesnt count till it hits the wheel).
Im betting someone on here knows the drivetrain loss factor ... who will chime in first is the only question. Got to love this forum.

Wow, that would make it 392 crank hp, not to shabby...
But from what I've heard a dynojet is braked less than one of our german dynos and gives higher numbers... So maybe that's only about 370hp or less, but still very respectable for a X MR...
In closing, I'd like to add: VROOOOOOOOOOOOOOOOM!!!

we could devote an entire thread to drivetrain loss theory. I've not seen any facts posted where someone tested on an engine dyno then on a chassis (awd) dyno for direct comparison in the states. That data may be readily available overseas where I don't so much surfing though.
I have to wonder if a fixed percentage would work though, higher rpm and higher power = more heat, more heat = more loss??

I have to agree with both mellon_tuning and boosted_tuning. One its different per car and it is inaccurate to use a fixed number for conversion. Now will it vary that much that a set number cant get you close ... no. BUT ... its also a little useless since it only matters how much you can get to the ground not what your engine puts out. This program will show WHP and if you need to calculate crank hp for whatever reason, you can find the multipliers online somewhere. Hope these two great contributors helped out. I trust both of these guys as they have helped me out tremendously.

So everybody is used to it and for "us" it's easier to compare that way...
It's a bit like if your speedo suddenly read in KPH instead of MPH...
Then again, I can go 260kph/160mph ANY time I choose to (without going to prison ), so it's swings and roundabouts... ;-)

FWIW the stock evo 8's were rated at what 276bhp? the typically but down about 240awhp. that's about 13% DTL, nowhere near the 21-24% some AWD guys guess. On rwd cars the old rule of thumb was 15% but I'm not sure if that still holds true with modern drivetrains which may less resistant.

Can someone make a graph of my car?

Is Evo IX in 4ª gear wheels with 17 " driver 100kg (220.5 lb)
Thanks!
