Hi Gents,
I'm in the process of selecting my turbo (stock turbo + manifold doesn't fit in the car) and wanted to get a representative dyno from the GT2860R. From what I've read it's close to the stock turbo, but I was still hoping to get a dyno so I could have a baseline. Please specify the turbine A/R used if possible.

Thanks,
Daniel

 

i have a gt2871r havent dynoed yet, im running 25psi, spools pretty quick, not as fast as stock tho. i have a .63 ar turbine housing.

 

What car is it going into

 

Caterham 7

 

To bad u can't fit lnf with zfr in there, that be one fast car. But if it was me, I'd make it fit. There is always a way lol

 

I have significant cooling system and torque limits (from the transmission). I'm going to be in trouble trying to reject enough heat to sustain 300hp and the transmission is limited to 300ft*lbs. It should be enough for a 1300lb car though .

 

with that many limitations perhaps you should look into a big wheel k04 such sas the k04R from turbobay performace, i had one on my car and loved it until i went big turbo

 

what transmission are you running?

 

modified Ford Type 9

 

ok i see how your limited then. cant say that would be my first choice of gearbox. myself, i would have elected to use a close ratio world class t5. they can take 350-400ft/lb in a 3200lb car, be near indestructable with a 4 cylinder in something as light as a super 7

 

The T9 wasn't so much a choice. It is what Caterham recommends (read: drive-shaft and trans mount setup for it) and it's really the only thing that will fit. The transmission tunnel is tiny. I had to machine flats in the drive-shaft output flange so that it would fit through the tunnel. The T9 is also very light (74lbs).

Besides, I hope Bugatti power to weight is enough to keep me happy for a while.
