N/A Street Combos

Unit 5302 · 06-13-2002, 07:32 PM

What kind of trap? Based on what type of suspension setup? What kind of car? My combo will make best power below your 6500rpm criteria. I don't believe spinning the bottom end to 6500rpm+ is a good idea for the engine performance you're proposing. While it can probably take it, there is no reason to run it that high with the combinations available. Not to mention the addition of a computer enhancement to remove the 6250rpm limiter, which I will suggest anyway.

Example. 1992 Mustang GT Hatch. Manual. Drag suspension. I want to run low 12's/high 11's with a trap about 110mph.

331 Stroker
C&L 76mm MAF
70mm T/B
Holley Intake
Adjustable FPR
24lb/hr injectors
TFS #2 Cam
1.6:1 Roller Rockers
TFS TW Heads Stage 1 port
10:1 CR
1 5/8" Long tubes
Off Road Long tube x pipe
2 1/2" Catback
190lph fuel pump
Aluminum radiator
EEC Tuner
Tremec TKO
Aluminum driveshaft
31 spline axles
Differential cover
3.73:1 ring and pinion
28x10.5 ET's
4cyl Spings
70/30 front struts
Lower/upper control arms
Subframe connectors
Welded torque boxes

The combo listed above shouldn't be spinning to 6500rpm at all. Probably 6000rpm or so, and is based on a Fox body Mustang chassis. I would expect the stuff above to run the times you're looking for, actually I'd be ticked if it didn't run a low 12, even on a bad condition track, assuming you're not talking 5000ft. Trap speed should be somewhere in the 115mph neighborhood. Take the slicks off and use it as a daily driver, pretty much.
