I have a 05 RS I am going to be putting race gas in and cranking it up. The engine has
Wiseco 1400 hd pistons ( either stock comp or 9.1 can't remember)
Eagle h beam rods
Stock crank
Ams Race shaft
Cosworth HG
Map head studs
Arp mains
Basically stock head with a new valve job
His 272 cams
Stock intake
Hta86 turbo kit from buschur (dsm housing) .63 a/r housing
1150cc injectors
300lph deatchwerks fuel pump
Buschur apexi exhaust
Tuning is ecuflash by 4wstuning via e mail

I want to put race gas in the new engine after i bring the car up to were I live now and let it rip. it's 110 oct and I was wondering what everyone's guess is that the car will make. I think I may run out of injector before we max the turbo out.

 

There is a sticky on this subject post it there

I would probley which out that 63 a/r housing for an 82 a/r housing. They say anything smaller than a 82 is useless. This is a quote from the FP site: "This turbo is available with a variety of turbine housings, but using anything smaller than a .82 is stupid."

 

Yeah i understand that the smaller housing will make the car choke up top but the car made 570 on straight 93 oct on 30psi on a conservative tune.
