Years ago we had a fuel pump go bad. Had pressure but no volume. Or a plugged fuel filter. It caused us a major performance loss and didn't affect the running of the car. No engine miss or nothing. Changed pump problem cured.

I lost a class race a few years ago to Bob because of a fuel pump failure in a "U" car. fuel pump just failed to keep up because of lack of volume.

That's the only way I can beat that U car! LOL

You said you ran 8 gauge wire from ign box to power source but ground to the block,I had 2 different boxes in 2 separate cars that gave problems until I grounded box directly to the battery.might be worth a shot......Victor

a few season's ago our car slowed down 4 tenths from one race to the next. After going through all the usual stuff in the engine.trans and so on it turned out to be the rubber hose in the brake line at the rear end had collapsed and wouldn't release the brake pressure all the way. Changed the hose and car picked right back up. Might be something to look at.

That sounds weird that you could lose 4 tenths and only slow down 4 mph. How did the short times compare to the first run??

Like Bill B said check your rubber brake hoses, I've had some that would collapse and hold pressure.

Keep us posted on what you find.

Good Luck

Changed pump problem cured. Also I've seen where someone is using a cheap brand of synthetic oil causing poor ring seal.

Spent about 1200.00 to find it was the pump. Had gauge mounted in front of windshield and always stayed above 6 lbs. So I chased everything else until I changed pump as someone suggested to do and shazam.
