Well boys, finally had a chance to get her on the dyno. Wanted to make sure the A/F was good, and was curious about the HP with the preliminary Lund tune.
First, want to thank Scott at Massdiesel for all his install help, and use of his Dynojet.
The first hit, the car made 641/599. This run was shut down at 5,800 rpm, as the Wideband shot out of the exhaust and we didn't know it did, we just saw the A/F go LEAN so we shut it down. Made another hit right after that, within about a minute, 618/588. Heat soak was pulling timing like crazy.
Let her cool for about an hour, and made 647/615. We pulled her to 6,200 rpm. HP was still climbing, but not much, not worth hammering it higher. Probably would have only made a few HP more if we revved it higher anyway.
Very happy with the preliminary tune from Lund. A/F was nice and fat and safe, with the leanest being 11.50 across the board up top of the tach. Not sure what the total timing is but I'm anxious to get into it more.
Soon, we will be getting the car tuned for max power. Right now, I am running 4.10 gears which will lower the HP you see on the dyno a little bit.
Toward the end of next week, the car will be receiving a roll bar, then it will have to prove itself on the track, which is, and always has been the real measure of a car's performance with me. I think it should do well though.:coolman:
