Car bogs in the corners, road race.

I forgot to add, I run a HEI with 90 degrees plug wires and 5-6 of them is touching the headers. I am wondering if I might be getting a bad spark at some of the plugs as the heat rises and the rubber get's softer and might be bringing the wires close enough to create a spark between wires and manifold ?

My guess? Non-sumped tank and losing fuel pressure when you add lateral force. What were your fuel levels when this happened? Stock pickup and sending unit?

The one constant you have every time this starts is that the car is in a relatively heavy G turn. So what changes in that situation? Fuel displaced to the outside on a flat tank with stock pickups. Pump starts getting air as the fuel moves away from the pickup. Initially there's enough in the bowls to run the motor, but under heavy throttle that will burn quick. Keep on the throttle and even after the pump stops cavitating, it can't catch up initially. Slow down in the straight, backing off the throttle allows the pump to get some fuel back in those bowls.

Somebody else could have a completely different opinion.

I agree, always race with as much fuel as possible. You dropped your floats so that shouldn't be the problem. I would reccomend a road race rear float and jet extensions, but I highly doubt that is your problem, especially the first time out.

I may be way off base but I think your pump needs to be in the rear of the car by the fuel tank as its designed to push fuel. You may be usng more fuel than the pump can replace with it it the engine compartment and only a short run to the carb.

Thanks for the ideas guys !
Fuel level was about 1/4, so I went and filled it up. Same symptons.
Yes, stock pickup and fuel lines, probably the smallest type.

Vegas69, any links to those floats and jet extensions ? Maybe not the problem now, but might be next time.. One funny thing, my cousin who is a far more experienced driver had way more problems with it than me... Who would have thought... lol

So, first thing I chould do is move the red holley pump to the rear. If that doesn´t cure it then how much pump will I need in gph to feed a 502 pushing 600 hp.

An upgrade in fuel department seems to be the way to go.
Pump, regulator, filter, fuel line, fuel sending unit etc. Will a stock 3/8 be enough from the tank, and then fuel lines of 1/2". Or where can I get 1/2" fuel sending unit ?

Although the red Holley is rated at 97 ghp, it is down to 20 ghp a 7 psi

Even the blue holley would be a major upgrade pushing over 90 ghp at 7 psi.

Looking at either the black pump or the hp125..
black is 125 gph at 7 and needs a regulator.
hp125 is 110 and internally regulated, which I like, especially if I`m not going to run a return line, which I haven´t decided on yet.
