Some updates on what has transpired.

First of all, my starting problems are all gone. My Prowler now starts on the first try whether it is cold or hot. My mind will have to get used to my Prowler starting on the first try because it used to take it 3 or 4 times to start.

Was talking with Bob Wyman and he suggested I drop my retard knob 1 or 2 clicks since I have more fuel coming in. My retard knob was sitting at 9 o'clock and I went ahead and dropped it to 8 o'clock. In theory this should give me a few more ponies to the rear tires.

Apparantley with my old fuel pump Paxton could not set it to this setting because my engine would start detonating at the top end (5500 rpms). At this setting they got 332 at the rear wheels.

After setting it to an 8 o'clock setting, I got on the road and did a few WOT runs. The boost seemed like it would not stop climbing. My rpms hit 6500 and I backed off because it seemed like my tranny was not going to shift into 4th. My heart was pumping hard. I did not hear any detonation and my engine did not flat line. It used to before at high rpms flat line and my engine would just sit there and I felt like there was more but no more was given.

I checked with the local dyno guys and they said they would have room for me next week wednesday. Will see what happens.

By the way, I'm running Deans headers without Cats.

I have enjoyed my Prowler even more these last two days.

Thank you again for your R&D...

I filled up the tank and did several hard turns and braking then I opened up my bracket again and there were no leaks. I have officially handed the tool to JD today.

He was pretty excited about having the tool.

Thank you for your support Al..

Here is my new dyno sheet from last weekends run. I'm pretty happy with the run and I don't feel comfortable doing much more with it. I need to tweak the paxton injectors to spray a little more from 3000 rpms to 5000 rpms. I was in the 12's (Air/Fuel)and should be in the low 11's. It hit the ll's once it hit 5000 rpms and this is attributed to the programming Paxton did with my old setup.

Since I added Deans headers and removed the Cats, my engine is breathing alot better thus running a little leaner from the get go. I gained 13 more horsepower from my last dyno run at Paxton.

This was achieved with 11.5 pounds of boost with my retart knob set at an 8 0'clock setting. I almost felt I could have set my retart knob to a 7 o'clock setting which means no retard at all. I was to chicken to try it though.

Once I adjust the fuel delivery from 3000 rpms to 5000 rpms, I think my horsepower might go up a little more.

Thank you AL.... I would not be able to do this with my old fuel pump. Not enough there to carry me thru.

AWESOME!!!

A/F RATIO

9.0:1 BLACK SMOKE (NO POWER)

11.5:1 RICH BEST TORQUE @ WOT

12.2:1 SAFE BEST POWER @ WOT

13.3:1 LEAN BEST TORQUE @ WOT

14.6:1 STOCHIMETRIC AFR ( CHEMICALLY CORRECT )

15.5:1 LEAN CRUISE

16.5:1 BEST FUEL ECONOMY (EXCEPT FOR HONDA MOTOR COMPANY)

18.0:1 CARBURETED LEAN LIMIT (EXCEPT FOR HONDA MOTOR COMPANY)

22.0:1 EFI LEAN LIMIT

GENERALLY ENGINES OF DIFFERENT BASIC DESIGNS HAVE THE SAME A/F RATIO REQUIREMENTS. THESE CALIBRATION NEEDS ARE TYPICALLY A FUNCTION OF OPERATION MODE, ENGINE TEMPERATURE, ENGINE SPEED, AND LOAD. GENERALLY A PRODUCTION BASED HIGH PERFORMANCE ENGINE WILL HAVE A/F RATIO VALUES IN A RANGE FROM 12.0:1 TO 16.0:1.

COLD ENGINE

I'm a serious gas guzzler now. I probably get horrible gas mileage now... I love it though

I had that power with the original paxton setup...

I kept track of my upgrades on this link.

Note: Review it and see how the power went up with every upgrade.

Later...
