Yes, that is indeed a flat torque curve - likely the benefit of the blower.

It's not that I don't want boost down low - I do want it available (and I do have it), but I don't want to have to use it so early as load increases.... and I think that's a function of the power band location..... in turn, a function of the cams. The engine just is not making power on its own down low.

The performance isn't as bad as the numbers appear. The Mustang dynos have a lookup chart for all vehicle models so wind resistance and weight are taken into consideration. The factor for my truck was 22 - the highest number the dyno operator has ever seen.... the old refrigerator on wheels. So, the resulting numbers are downgraded accordingly. I'm no dyno expert, but I'm told that a DynoJet would probably show up to 40HP more. If instead we were looking at 150HP/180TQ + estimated driveline losses raising it to say 180/225, we'd be saying "Wow!" <img src="/forums/images/graemlins/lol.gif" alt="" />

I was concerned that fuel was limiting, so I did watch fuel pressure as the engine spooled up on the dyno.... it started at 43psi, climbed to 60 and held steady.... so that appears to be ok. The next thing I'm going to do is a compression check to make sure the rings are ok.

Meanwhile, I'm calculating LSA and valve overlap on the 24v non-turbo and turbo heads - noticed those cams are tighter than the Diamante or Montero cams... interesting. There's always the option of custom cams, but I'd rather not go down that road.

I'll be in and around Atlanta for the next couple of months...... maybe I can arrange a drag race with one of the locals and see the real world difference. <img src="/forums/images/graemlins/wink.gif" alt="" />
