BR 2.0L FP Black BR BF272 cams E85 & 93 results - 630whp+
#18
Ya your combination in parts worked great. very nice responsive car.
I think its 9.0, but i agree it is nuts how it can take that much boost. its almost like the gas is way higher octane or something. since this tune, i haven't seen 93 perform like this car did yet on it.
That FP 71hta came close though. his gas was really good also.

Do you think it might be the BF272 cams allwing the high boost on pump? There have been a number of cars out of Buschur Racing with 30+ psi on pump. When my car had a Red, David tuned it at 32 psi with those cams. I later swapped in a Black and it made 500+ whp on pump at 31 psi. Since the cams have a good deal of overlap, it might lower the dynamic compression ratio and allow the additional boost on lower octane.

another 2.4LR i do with the BF 272 makes really good power on 93 also. now in 4th we don't run the same boost curve though since we have ecu boost control.
you're right though. there was a lot of high hp white evo's on 93 i remember. they all had his cams too.
