Kenne Bell 2.8h

[blwn03sonic]

Just purchased a 2.8h from a member in here. This is my third 03 cobra. First was a sonic blue with a steigy port with 2.76 upper made 488hp. I’m on my third cobra black 03 10th anniversary. I’m going to be running stock pumps with a bap sct maf. Looking to see what pulley I should run for pump gas. I want to get a very conservative tune. I think it will be coming with a pulley good for 17-18 lbs of boost

Stock pulley 3.75" and if your running headers... add a 2lb lower as the boost will drop 1-2 psi.

I recommend no more than a 3.75" pulley unless you have custom ones made for street tune.

 

[blwn03sonic]

Yeah. I was thinking that or the 4 inch one

3.75" is the stock pulley, 18.5 psi. My stock pulley is super close to the stock hood. I really doubt you could fit a 4" pulley without rubbing on the hood.

 

[blwn03sonic]

Damm. Okay. So I’m sticking with the 3.75

The 4" fits under my hood and does not rub. My street set up is the 3.75" with a 2 lb lower. That gives me roughly 20# boost, but there is a little Torco in every tank. I would run the 3.75" with now lower in your case.

Same as me, stock blower pulley with 2lb lower on 93. I swap on the 4lb lower for corn, which is 99% of the time.

What sparks plugs you guys running. I’ll be running the 3.75 upper stock lower and would 80lb injectors be good.

Put you a return fuel system on it with a 3.10/2# lower on E85 and rock out lol.

 

[blwn03sonic]

That will happen later. Need to just get this sucker on and tuned for pump fuel

Tr6 plugs gapped at 0.028-0.032". I make 700 on e85 with 80's and there is still plenty of room left on them.
