sir seven

I just blew my engine



i was wondering if any one new about how much

power i would get from a bridge ported 12a



i want to know because i just put my car in to get

the engine done and im getting the original 12a bridge ported

I dont have a clue, but I think I read somewhere that it adds like 25% more power on top of what you have. Dont quote me, but I think that it adds about 25% more.

it depends on how big the ports are, and the exhaust, and the intake. it should be 200rwhp+

Sorry to hijackyour thread but......



What about a 13b mild port. NA. Headers. Desmogged & decatted (is that really a word?) High compression rotors. Not sure what compression ratio, but high compression as against the original turborotors that were in it when it died.

prolly somewhere between 160-175, again it depends on the rest of the combo, size of the port etc.



heres a little approximation, this assumes good intake and exhaust setup



stock 12a 140-150

sp 12a 160-170

big sp 12a 180

bp 12a 180-200

pp 12a factory says 280 flywheel hp



stock 4 port 13b 160-170

big sp 4 port 13b 200-210

bp 13b 230*

pp 13b factory quotes 320flywheel

13b 6pi 140with stock manifolds/ecu

13b 6pi 160-170 with ecu/ported manifolds



* we had a bp car on the dyno and the dyno only reads up to 9600rpms, the bp was still going
