i just have the ms3 cam and stock heads, stock injectors were at 98% duty cycle i believe on motor with just the ms3 cam,my car is 3,420 without me in it 3,620 with me in it ran best pass is a 7.47 in the 1/8. my car is auto so cant help ya with the clutch part.i would go ahead and get some bigger injectors you can pick up some up on here used for cheap, i run the 42# svo green tops.
Get 42lbs now, they're like $320 for some Racetronix/Delphi's. I didn't and I am pretty sure you will be making more power than I am and I was triple digits duty cycle on the dyno.
I went with Monster Stage 4 because it was the same price as Stage 3 and holds 775 lb-ft. I would not recommend this for the street though. As it heats up, SOB grabs and grabs HARD. Only thing I can do is rev it up and dump the clutch and sputter away. Took some getting used to for sure coming from stock.
When I originally was dyno tuned, we could not get a 4th gear pass to rev to 6800, the stock clutch would slip @ IIRC, 6400 everytime. I could not enjoy the new found power of the H/C with the stock clutch. I replaced that and I still cannot enjoy the power, fully, until I replace the injectors! I won't do more than 2 gear pulls @ WOT due to the duty cycle, and that is more than I should with triple digit duty cycle.
