2.8 pulley w/stage 2

endub · 10-04-2006, 09:58 AM

Who's running this setup? Will it lean out the A/F ratio? What kind of boost. My only mods other than stg 2 is K&N typhoon. Thanks.

I've got the stage II w/ a 2.8. Excellent setup. I ran consistant 12:1 A/F on the dyno. The duty cycle on the injectors is a bit high but it still runs great.

I run this setup on my SS and its good. However I ran my friend who only had Intense Stage 4 PCM with a 2.8 pulley and he pulled on my every gear no problem.

Thanks for the advice guys..... I know I need colder plugs, but with what gap? I'm still on stockers now, but plan to change when I put the 2.8 on.

Also, I'm gonna take the car to a dyno when all is complete, but what kind of numbers should I expect? Have not baselined it yet cause I had stage 2 installed when I bought the car.

NGK BKR7E's gapped at .035" works great for me. Any larger and I would get blowout and some stumbling at high RPM.

What octane gas do they have where you are? If you can run 93, you can even run about 1* of timing more in the higher rpm if you wanted too. If you are running 91, I would just leave it alone.

93 at most filling stations. Although one place has 101 octane

. Occasionally I mix some of that in with 93. Do I need an HP tune to bump the timing?
