Probably not the clutch then. I am interested if that shield is holding it back though, how much clearance is there around it and the filter element?
Dyno doesn't mean everything. I bet this one will run quite a few mph faster and be able to repeat the power it puts down better over a 2.3L. I too dynoed my car hot and put up 3 pulls within 10hp of each other with only a 5 min cool down between 1 pull. The other one was back to back. This was after a 2.5 hour drive to the dyno so the big blowers don't seem to heat soak as bad at the more moderate boost levels vs a 2.3 sized blower.
Look into the magnafuel pump though, it will save you quite a bit of money over a Weldon and they perform well.
ProTuner In-Line Pump MP-4301 you want the 4301 at min I would opt for the 4303 pump due to the E85. Ask them what they think for a pump on your setup.
not a lot of clearance at all around that side of the filter where JLT cover wraps around. I only put the black cover on to hide the blue Amsoil EA filter....next time will do a dyno pull with it on and off....to see the difference.
thx for pump info, will investigate further!
