Hey guys, I`m building a 331 stroker with AFR 205 heads, Anderson Ford custom cam, and a TDC twin turbo kit. I`m using a R302 block, and Probe industries Pro Street stroker kit(all forged). My question is, How much horsepower do you guys think this set-up will make? I`m using 50lb injectors with a complete aeromotive comp fuel system. The turbo`s are the T3/T4 hybrids, I`m gonna set the boost at 14lbs of boost. Any ideas or pointers would be greatly appreciated.. Thanks!

 

2000hp easy

 

Im detecting some sarcasm. You would think that a 331 with 14lbs would make something around the 600rwhp mark. But thats my .02

 

should do it depending on the tune. you will likely run out of injector though unless you run close to 50 psi base fuel pressure. what engine management system?

 

Your going to run out of injector before anything else, why so small? You'll be lucky to get 600 jackstand hp out of those.

 

I figured I would need bigger injectors...What size do you think I should go with? Sorry I`m also going to be running the PMS IV series on my car.

 

I have 60lb injectors in my car that work pretty well. I dont know what kind of duty cycle they are at, but i think they would work well for you if you intend to stay with a high impedance injector.

 

83 lbs

 

150#

 

19#

 

42 50 psi

 

My 347 with the TDC 2x kit put 670/720 corrected to the tires at at 15-16 psi but the turbos were all done at that point, due to the hotsides maxxed out flow the power flatlined after 5100rpm.

 

Thanks for all the input guys , Turbofox347 the numbers you are producing is about where I wanna be.

 

I'm making 540 rwkw with 55Lb injectors at 35 Lb fuel pressure and through the whole dyno run she's right on 11.5 afr..
Mind you I have two 044 Bosch pumps and twin -8 feed lines to custom fuel rails, Magnafuel fuel reg..
Running two SC61-2's..Changing exhaust to twin 3"..Next tune I will increase fuel pressure to 45 Lb though...
