Nice numbers. Did you mean the 150ft-lbs of torque jump? [Wink] But yea looks like the cam and nitrous are running good together. I thought the nitrous would produce a little more power though with the nitrous cam. Still looks like you only gained roughly 100hp. You still have stock internals and heads don't ya?
Yea, 150 ft-lbs. I'm just a dumb engineer who can't read a graph. I fixed it.
Stock internals and stock heads.
I was just looking at the log of the N/A run and saw something interesting. The MAF reading maxes out at 6000 rpms. If you notice, the HP just disapears at 6000 rpms. This is strange since all the limiters are set at 6400 rpms. I think there is some sort of limiter there that I can not see with HP tuners. I am going to post this info on the HP Tuners forum and see if they can explain. I should be able to gain power up to 6500 rpms with my cam and springs. On the nitrous run, I stopped shooting at 5900 rpms.
This is something I have known about for awhile. My last dyno I was maxing my injectors so I was not sure if that had something to do with it. That is the main reason I went back. Its not the dyno, its the pcm doing something. I hope HP Tuners can figure out what table we are not seeing so I can run up to 6400. This explains the track times a little. In 1st, 2nd, and 3rd I was running up to 6400 rpms. With no power from 6000-6400 I was spending the following times in each gear in those rpms
1st .4 sec
2nd .5 sec
3rd 1.4 sec
for a total of 2.3 seconds. That is 2.3 seconds of the 1/4 mile run where the only power is coming from the nitrous. I am looking forward to getting to the track and seeing if shifting at 6000 rpms will help.
