Going over some logs, we noticed the car was leaning out pretty bad in first gear. Once second gear hits, everything seems to work out fine. I assume the pump can't keep up from the initial hit of the kit.

It is a wet plate kit, the noid is going to the stock rails, with an upgraded pump.


anyone else run into the same prob?


There anything to help with it besides a standalone or upgrading the pump?


Like I said, once the car hits second gear, everything is fine.

I was having fuel pressure problems on 1 Walbro pump and hotwire kit pulling fuel off the rail on a 100 shot. I added a 2nd intank pump and fixed it. Not sure why would have a problem in just first gear though.

what kinda power on motor and how fast does it 60'?
im guessing gas is sloshing or its spiking the rail...but unuseual on a small shot...new fuel filter!

how lean is it going?

Not sure on the power. 400RW?

We'll have it back @ the track in the next week or two and will try it with more gas in the tank.

gets leaner and laener as the RPPM's climb, prob 18:1 IIRC.

I'm pretty sure he is just spiking the rail.


Trying to talk him into this setup so we can log Fuel pressure.
