Just got back from a dyno session at Texas Speed & Performance, I've been nervous all morning hoping everything would work out okay. I think I was more nervous than the day I got married!
As many of you know, I've been doing part throttle and cruise tuning on this car for quite awhile with help from a friend of mine [John Ginter]. The tuner at TSP commented on the overall idle of the car and how it did on the cruise and that it was doing pretty well. He did 4 or 5 pulls with cooldown in between. He was just trying to get the AFR just right, finished it up around 12.9:1 and it was pretty happy at that point. Open longtubes were creating a little noise issue with the knock sensors, he said it might have made a little more without it causing havok on that.
Going to look at getting a new harmonic balancer to help with spinning this thing up above 6K at the track since this thing without a balance shaft vibrates like crazy.
Just getting there:
3.8 Liter capacity strap-on:
Hot under the collar:
Anyway, numbers.
3rd gear pull, unlocked 3800 stall:
196.02 hp @ 5600 rpm
196.33 tq @ 4600 rpm
2nd gear was a little cleaner line:
195.12 hp @ 5750 rpm
206.14 tq @ 4600 rpm
These weren't really power pulls more just to get a good tune. He didn't want to lug it too bad in 3rd with it locked out.
Compare to stock 'verter/trans and 140K mile motor:
184 TQ @ 4700 rpms
169 HP @ 5300 rpms
I am honestly pleased to see these numbers through a big stall. There's so many things that have changed on the car that just looking at the numbers it is hard to really compare the two as this car is very different from when I first started.
Going to the track tonight, running the 1/8th and hopefully get some times for tonight.
