I went to Shawn church's yesterday and I was getting my car tuned by Daniel. He got it up to about 340 but then it started having fuel problems. He didn't tell me too much he just told me it's not getting enough fuel. He told me to check the fuel pump, the fuel filter, the fuel pressure regulator, and the injectors.

I'm not too experienced in the fuel department, so I'm not sure of how to diagnose this. The fuel pump primes and it does work, I don't see how it would stop working after 350. The injectors are RC 1000cc with resistor box, I bought them from someone but they were new, they still had the hats on them, the fuel filter is new, and the fuel pressure regulator is oem, but I'm sure it doesn't max out at 350.
Also he said to check if the fuel lines are clogged. How can I go about diagnosing this?

My setup is

Benson sleeved 83mm b18c1
Eagle rods
9:1 CP pistons
Benson micropolished crank
ACL bearings
Garrett gt3076r
Inlinepro log manifold
Supertech Valvetrain
Walbro 255lph fuel pump
Oem fpr
Autozone fuel filter

***Cheap autozone fake stainless braided fuel line from fuel filter to fuel rail ( stock one didn't reach victor x manifold***

the autozone fuel line is the only thing I could think it is, but what would I use as a fuel line (what diameter) from fuel filter to fuel rail?
Also he said "boost is going into the block" what the hell does that mean?? I've never heard of that...

I have pictures of the dyno with AFR if needed

First thing I would do is check fuel pressure. 94

And to do that I just get a fuel pressure gauge and it goes on the fuel pressure regulator correct? What pressure should it be at?

madblkscientist

you can put it on the rail or the fuel filter bung.This will tell you if the fuel pressure is falling off at 350hp


is your pcv system still hook up cause if so then it is feeding boost via the breather hose on the valve cover remove that and put a filter cheap fix, but you might wanna invest into a catchcan setup or route it like a 4g63 system althou most ppl dont like that setup

The pvc is still on but it doesn't have the hose attached. The PVC valve is just there. And then the hose that comes out of the vale cover is routed to a catch can, but the catch can isn't routed back into the engine, it just ends there, is that ok?

As for the fuel problem, I'll get a fuel gauge and check that out, what else do you guys suggest?

madblkscientist

i would goto a full catchcan setup removing the pcv and if that doesn't help then you might have really bad blowby

Destructive-

Just take out the pcv valve and leave the hole there just like that? Or do I also remove the black box that the pcv is in? I think I'm gonna make the catch can setup from the valve cover as well, the one that comes out of the front like all the super-cool setups have it? Hahaha, what do you think?

madblkscientist

leave the blk box and hose going to it but remove the pcv 4 now till you get the catchcan system or better yet wait till you get the catchcan system and all the parts needed to convert over and it will come with the parts neccesary to remove the black box, and modify the valve cover

but it reallys sounds like there is another issue bcuz i've ran cars without having to go all out cacthcan

going through my old threads

issue ended up being bad injectors / bad resistor box. switched to 750cc saturated RC injectors and GTG!
