Back from local dyno day....

[DMAN302]

Well last time the dyno numbers were decent 291/317..but so close to 300 I wanted to try a few changes and see if I could make it..
Well with the addtion of a Taurus fan replacing my spankin new clutch style fan, and goin to a 94 octane program that added some timing and leaning me out from the 12.4 A/F I had with the lower octane program on my chip...I had some decent luck.
First run after changes corrected:
305.1 and 341.8 torque ...I was VERY pleased...then the next run...
316.5 and 344.5
No changes were made between the runs 5 minutes apart!
I notice the numbers and the power curve as a little different, didn't do A.F monitoring this time and I think the pump may have been an issue on the first run..don't really know.
Now the bad news is on the way home my fuel pump started squalking strangely..and every time she squaked..the car would stumble..lose power or stall. I also noticed my fuel pump relay was gettting HOT...so first I replace the relay...stay close to home, and if it continues then my 600 mile walbro 190 pump goes right in the trash

Very impressive, is there much of a difference between the regular edelbrock performers and the RPM's? Are yours a out of the box pair or were they worked. Nice numbers either way.

Thanks..the heads are small valve RPM's with some port work on the exhaust side only.

Were two different types of dyno's used from the 291/317 run to the 316/344 and 305/341 runs?

Nice numbers!!

Same dyno different days. I found the torque increase was pretty high but I assume that it comes with the A/F leaning up a bit, and getting rid of the clutch fan...that unit was very tight and hurting quite a bit IMO.
