I have a 98 Camaro with a D1SC, Headers, ORY, 3 inch exhaust, Comp Cam, pushrods, etc etc. Car has a 6 speed with a 9 inch. I recently had the car Tuned but was unable to finish the Tune because of the Fuel Pump running out of steam at the top end. It has a stock pump in the tank and a pump inline. Wondering what everyone is running to support around 600 RWHP. There is so many out there, not sure which one to get. Ready to have it done though.

Also the rear whines on the car pretty loud. It has a 4.11 with a locker. Wondering what would be a good gear to go with or stick to what is in it just get new ones?

Any advice will be appreciated. Can give more details if needed.

Thanks,

I make a dual intank pump setup specifically for your car. It will support power levels well into the 1000rwhp range.

This pump setup can be run as is, with the stock lines, or used as part of a complete fuel system, complete up to the rails & back.

Feel free to give me a call to discuss. I have night & weekend hours as well.

I will give you a call. I don't want to replace the fuel lines yet. That will come when I build a bigger engine. Trying to keep it a simple fix with a bigger pump. I will call you so we can see what you offer.

Thanks,

Anybody else have any suggestions?

Two Walbro pumps together will handle 600 rwhp with the stock fuel lines. I would try a new set of 4.11 gears, it can be a hit and miss on whether the gears will make too much noise, even with a perfect pattern. Bob

I've seen the majority of people have success to around 650RWHP with stock lines before fuel pressure starts to rapidly drop off.

Above this you really need a front mount regulator for stable pressure control. Near this power level, one is generally running enough boost that a front mount regulator, with boost reference capability, is a good idea. This helps to increase the capacity of your injectors under boost.

Personally a front mount regulator is always a good idea for stable fuel pressure.

The most cost effective way to fix your problem is to do twin walbros in tank and put a regulator upfront.
