My baseline with BBK headers, off road h-pipe, magnaflow catback, cai, timing at 15 degrees, and the smoge equipment deleted was 220.5rwhp at 4700 rpms and 285.1rwtq at 3600 rpms.
After installing thumper heads, 1.7RRs, new lifters, TFS track heat intake manifold, 65mm tb, timing set back at 9-10 degrees, and an accel FPR, my car put down 248.7 rwhp at 5300 rpms and 287.2 rwtq at 4200 rpms. I think it should be making around 20 rwhp more than that based on what I've seen very similar combos put down. I know its over intaked but I got a real good deal on that intake and all the bigger intake should be doing is shifting the power band to the upper rpms. The fuel pressure was at 41psi with the vacuum line off.
The dyno operator says I could see 20-30 more rwhp by getting a tune but thats $500.
Im thinking about dropping the fuel pressure to 39psi and advancing the timing to 15 degrees. Im also going to check the plugs. I think its probably running way rich. Keep in mind this is a speed density car and both pulls were done on the same dyno.
Any insite would be greatly appriciated.
