i know that it will loose a bunch on through a th400, I was asking because you should be able to support 900 or more with twin walbros on gas.

Now, the single power wire could be hurting you alot. But i dont know that. Was just curious bro, thats all.

Youve done a great job thus far, throw another power wire in there and let her eat. what size injectors again??

Dekka 60s. I think i can get in the 700s with them and the right pressure.

Thanks chris

Unless your hot wire consists of 16 ga wire you shouldnt be having a fuel pressure problem. Sounds like a leak or another issue to me. Good numbers at that boost level through the 400 though.

I have the racetronix kit. Its 10 gauge i think. lonnies said that its the wire, so i will give it a try. its a boost ref reg, so as boost rises so does fuel, so the pumps draw more power, which the 1 wire cant keep up with. i dont have another idea right now, so i will give it a try.

There are no leaks anywhere. if the wire doesnt do it, maybe its a pump???

Thanks chris

I highly doubt the wire itself is the only problem. The boost reference doesnt really matter either, you could unhook that boost reference and pressure would still fall from the base, you just dont have enough fuel flow.

U have a leak inside the tank, wiring issue, weak pump(s), etc.

I will check in the tank for leaks, and run the wire, any way to test the pumps?

Thanks, chris

Do they both run all the time or does one come on with boost? I always check my fuel systems in a bucket going through the regulator to see any leaks or to see if one pump isnt working as well as the next.

That looks cool man.

If you're having fueling issues, don't race it until you fix them...if it see's a different load at the track than it did at the dyno and you go lean you might have an expensive boom...

So do you have a Garrett GT 4276 or a Precision turbo? Kind of confusing on exactly what turbo you have. I agree with the others about the fuel issues, sounds like you're running on one pump. Maybe the relay or hobbs switch isn't kicking the other fuel pump on.

Its not having fueling issues @ 9 psi. When we were trying to do 12 it was running out of fuel.. So we turned it back down, and its ok. I have a wideband and hp tuners on the car, so i can log the runs.


Thanks, Chris

Turbo is a PTE4276, or gt4276.. It says precision on it, and 4276 with a 1.12 ar.

There both off the same wire, no hobbs switch. So if its the relay, both wouldn't be on, unless 1 pump took a crap. But lonnies, and the tuner didn't think we could make 590 to the tires through the th400 and the 9 inch with only 1 pump...

It will get fixed, just have to figure out whats going on.

Thanks, Chris

We can leave it at a 76mm Precision turbo. We are going to open up the tank and check up on things friday night. There is no relay,or hobbs switch for the second pump, they are wired together. So unless one pump died they just arent getting enough juice.

Hah! You could leave it at precision 76 mm, but it is not the 4202 which is smaller then what i have. The 4202 is rated to 1000 hp, and the 4276 is rated till 1200.

(on a much smaller motor of coarse)

This is a T6 or T4 turbo? I wish precision's website would actually display all their turbos. Car is going to rip!

Yeah, no doubt those are good numbers for TH400 and a 9 inch car. Congrats man.

Seems similar to my setup, but im on a precision 78mm running twin walbros, and im at 70 psi under 8# of boost( 62 psi base with 8 pounds from the regulator under boost). Good numbers, cant wait to get mine on the dyno, only difference is im running through a 12 bolt....congrats and keep us informed.
