As the owner of a Stage 3 ported "PIGGY" with dual Focus, 2400MAF, I can assure you I have NEVER, see this...NEVER beat a pullied UNPORTED EATON....it ain't ME, PORT JOBS are only good with 2.93 & 4lb lower, or even better, the 2.76 with a 2lb lower, ( I don't have a lower pulley do to all the BS associetd with that) and you should still be OK with the factory injectors, but maybe NOT, I don't know.
Why are your heads ported?
Please, just save the money and time, and get a whipple, or pay more for nothing and go Kenny Bell, I guess he's cool or something, I haven't figured that one out yet. But don't bother porting your blower unless you really want to keep the car looking stock, well then a stage 4 and a 2lb lower is a good move, especially if you open it up and top it out a few times a month, that's all a port job is worth, looking stock and fooling competitors, but you won't make the power you need to REALLY mop'em, for that you need a new twin screw, and it's Whipple FTW!
No offense to ported cars, I just wish I would have gone twin screw at the same time, and like I said, a pullied Cobra with a tune is just fine.
OK, OK, I am a little depressed since I have decided I've run my LAST 11.90. My best is an 11.7 BEATING THE FKG SHIT OUT OF MY CAR, and would rather just shift quick comming out at 42-4800 instead of 5-6200. I like the IRS car, axles are cheap, and I like the progress Cobra Jack has with his path, so I have become convinced to follow him. I think I'm gonna get some cams also because I love the sound, and that's important to me. I don't need high 10's, I just want low 11's. What I really want is GT500 with a Whipple, some rear end hookage and durabilty parts, a single piece drive shaft, low 11's, AWESOME SVT ENGINEERED CAR, end of story. :burnout::burnout::burnout:
