[QUOTE="bigja01cobra, post: 8682006, member: 91090"] Ok here is all info on block cams and everything. Installed in a 2001 SVT Cobra. BLOCK Balanced and Blueprinted 5.1L Stroker 3.750in Stroke, 6.000 Rod 11 to 1 Compression All Forged HEADS 01 Cobra Head shaved .010 5 angle valve job Hand porting New Spring and Retainers CAMS Comp Cams Intake DUR. 234 @.050 Valve Lift .475 @ 112.0 centerline Exhaust DUR. 232 @.050 Valve Lift .450 @ 116.0 Centerline Ignition Stock NGK TR6 plugs INTAKE K&N Cold Air Intake BBK Throttle Body Stock 01 Cobra Intake EXHAUST BBK Ceramic Coated Longtubes BBK off road X-pipe Flowmaster Cat-back TUNING Tuned on dynojet using sniper tuning software Total Timing set to 26 degrees DYNO NUMBERS 316rwhp @ 6300rpm 293.85 tq @ 5300rpm Air Fuel Ratio 13.0-13.3 throughout pull Curve is nice and flat just a steady increase to 6300 stays level till 6500 then starts to drop. The car was broke in on the dyno. To set intial tune, no full throttle pull. The car was driven for approxiately 150-200 miles. It then was strapped to dyno for pulls car put down 309 with 22 degrees of total timing. Car was driven for about 100 more miles then retuned again putting down 310. Finally after driving car another 100 miles timing was up to 26 and the car put down 316. Car currently smokes a little under hard acceleration. Cam can deffintely be felt in car. Currently the cars likes to die at lights on occasion and immediately after starting. The car sounds like it has a turbo on it, I was told due to TB. Also car backfires on the 3-4 shift, but only there. Currently gas mileage is way down between 15-16mpg, before it was at 18-20. On interstate I an only getting 18, before I was getting 24. To me the cars runs a little rough, but I was told that was due to the cams. By my seat of the pants measures, it doesn't feel as good as it did before. Before from a roll at ~15mph I could nail it and it would roast the tires and when I would hit second it would roast them again. Now at 15mph it doesn't spin at all and shifting to second yeilds a small chirp. Car put down 320rwhp SAE with a stock block with only CAI, ford racing shorty headers, basanni catted x-pipe, flowmaster catback, UDP, throttle body, and a dyno tune. Just doesnt make sense that the car would not make more power. Most people with the similar setups make at least 335 where as most are above 350. I dont see how it is possible to have only gained about 50 hp over stock with all the mods. Just the exhaust and intake should have put me there. On top of that it is putting out less then it had before the heads, cams, and better exhaust. Any ideas as to what could be that problem? Any help or ideas are greatly appreciated.
