Update:

Finally got it on the dyno and finalized my tune today.
Results 672 rwhp on the same dynojet as before. Net gain of 58 hp over previous dyno of 614 rwhp with same mods, just not the cam.

And before anyone asks, yes these are the SAE numbers.

I thought I saw you made 623 not 614 before?

I lost 3 lbs. of boost after doing my Cam and headers...I also went with the 9.55 Pulley on the bottom..Ended up with 1.5 lbs of boost over stock.

I also lost about 2 lbs boost but the blower doesn't generate as much heat as it did making 15 lb boost. IAT2 only rose to 120 deg on the dyno.

Before cam and after cam dyno results. Only change over previous mods was the cam and valve springs, push rods and retainers.

JamesZL1 · 10-09-2014, 11:27 PM

Chart looks really good..you made power everywhere...Wish I could see the RPM's vs. the MPH, but it looks like the car pick a good amount up in the mid range and allot more up top...

Yeah ,me too. But the graph kept truncating the run and couldn't see past 6100 rpm if graphed by RPM. But the old run went to 6200 rpm and the after cam runs go to 6700 rpm.

623 was STD correction, 614 was SAE

Updated:
Newest dyno numbers after some further tuning. Brings total gain from the cam to about 80 rwhp. Run 541 was before the cam. And this is the same run as the 614 rwhp. Total rwhp comes up different when graphed by rpm instead of speed. But people mentioned they wanted to see rpm. It was only the previous dyno graphs that wouldn't graph correct with rpm.

ZO6 Bryan · 11-25-2014, 01:39 AM

Here is all 3 days graphed together if anyone cares. BTW I downloaded the Dynojet software so can save the runs and view them later to compare runs and graph in any correction factor. SAE, STD, uncorrected, etc. or rpm or speed.

ZO6 Bryan · 11-25-2014, 01:49 AM

Here is graphed with AFR

BTW stock rocker preload is 1 3/4 turn to 1 7/8 turns. Figured I would check with the stock parts so I can verify the new pushrods will be correct length and give similar preload.

Bryan,

Was your rocker preload still 1 3/4 - 1 7/8 after the swap or was it closer to 1 1/2?
