OK so heres the deal. Got on the dyno.
260ish whp and 240ish wtq
What the hell is wrong with my car. It sure as hell feels faster than that. The a/f ratios were in the 10.5's. But I dont think that changing that will affect it 100whp. What should I start checking. The guy at the dyno thought for sure it has something to do with timing. I have the timing set at 20 at idle like im supposed to but I can see anything from there. Any suggestions/theorys

Efeezi or Elks cannot remember which one had a similiar setup to you (subtract Enthalpy and add custom dsm engine managment) and had the same issue as you, he ran 25psi (I think) and made 275rwhp, If I'm not mistaken his cams were not correctly lined up, don't hold me too that, but find his dyno results page for further info.

275 at 4000rpms maybe My H1C made 411whp at 15psi and 411whp at 20psi meaning the turbo is past its efficiency range at that psi.1wheelwonder wrote:Efeezi or Elks cannot remember which one had a similiar setup to you (subtract Enthalpy and add custom dsm engine managment) and had the same issue as you, he ran 25psi (I think) and made 275rwhp, If I'm not mistaken his cams were not correctly lined up, don't hold me too that, but find his dyno results page for further info.

I had my cams messed up once and I didnt even know it. I couldnt pass emissions and then I found out my cams were off a tooth. I forgot to use a monkey wrench to turn the cam before I installed the sprocket so the intake was off a tooth or two IIRC..This is a fairly common mistake
You dont really NEED cam gears for JWT cams but you must at least get the cams on the right tooth.

Yea that was me with crower cams. I had issues with them they were off a 1/2 tooth and I lost 100whp from it. I put stock cams back in and gained the 100 horses back. When I installed them, I didn't have the intake lined up correctly and it smashed the dowel pin in. The cam must have turned a little bit when I was tightening up the bolt on the cam. So I would recomend at least double checking the cams and making sure the same thing didn't happen to you. And if it did I would order another cam cause it may have cracked it and you don't want it to come apart in the engine. My cam actually snapped in half when I took it to the machine shop to have a new dowel pin put in.
Or as efeezi says it may have something to do with the turbo, ( he knows his holset's )
Cause even with a/f's in the 10's that shouldn't cause a 100 horse loss. Maybe 40 at the most.
Just some thoughts.

I dont know if its the cams. When I first started myt motor and drove it after rebuild, It would take forever to start and it was hella slow. I found out the cams were off. I moved each a tooth over and now it starts up right away and its got power. Is it possible they are still off. Will the car run " well " even if the cams are still off. I mean, it drives fine around town, seem to have some power. I got 28mpg last tank too on the freeway. I will check my cams again today if I have a chance. But like I said, my main question with this is. Even if they are still off, would the car run well?????
