Frank/TTFS is spot on here guys. It was my car, at the shop, with me, Frank, Stash1 and Austin (can't remember his forum user name), working with Frank most of the afternoon, and night until 2am...
On HIS dyno, not dynojet calibrated, my car did a base run at about 260ish whp (I was WAY wrong on the butt dyno!) and some GOD awful torque number like 230ish... Left with 340whp, and 278wtq. We found the cams were off by 8 degrees....

Every set of these 288/280 cams i've worked with so far has required a negative DME offset to bring the camshaft around the zero adaptation range, rather than the retarded stock CSL value. It all sounds related to the same issue.

Hey Paul,
It was 5 on the intake 3 on the exhaust. I set the adaptation to 2 degrees and worked back from there. In a perfect world I would have liked to set adaptation to 0 and park the cams but at that point you would need to get them closer mechanically, the play in the splines, chain ect and delay time between the cam sensor and the crank sensor won't let you get that close or at least I was not able to accomplish it. When I tried it went over the cliff so to speak so I settled for this approach.

Wow a lot of new information here I've been digging for for months. Looks like I'm up against a lot more than I had imagined. Regarding the IAT's, I'm picking up a stock box from a friend today to hopefully try to get those down. With the head gasket, how much is .02 really going to knock down my compression? Half a point maybe? And this is before taking into account what was machined off the head right? Again what i gave for compression numbers was really just a guess from memory I'm not sure to be honest. But I did do the head gasket with intentions of future forced induction so I guess that's just something I'm going to have to live with until then. Will definitely get this thing on a dyno with Frank as soon as possible to get this sorted.

So now that the issue with cam timing is known is it possible for the TTFS guys to tune correctly remotely without tons of dyno time?
All this talk of hours on the dyno worries me. I'm out in California so would that mean strapping it to a dyno, datalogging a pull, sending that datalog over to TTFS, waiting a week, then getting on the dyno again for every trial and error change to cam timing? I hope these 288/280s are worth the hassle... |
