My setup is a forged 346 with my custom truck manifold 3inch GT-42 76mm turbo kit.I still have my stock 98 heads and a small 220 550 114 cam.I also still have stock fuel lines,reg,and rails.
Question
Would I gain more from some stg 2 CnC 6.0 heads and a bigger cam 228 582 113 cam.Or would I gain more from a Speed Inc fuel system to up the boost.
I am currently running 12-15psi with meth.I plan on doing both but just have money for one of them right now.

How is your fuel system doing now? Would it support the extra power if you buy heads/cam? If your fuel system is even questionable I would upgrade it first.

ya, id upgrade your fuel system first.
then heads and turn up the boost ****.

I know my injectors still have alot left but Im not sure bout the pump.How much more boost could I run with the stg2 Speed Inc system.It has two inline pumps,boost regulator,rails,lines,ect.

Definitely fuel system.

You don't want to have limit making power or lean out under boost because of a weak fuel system.

What kind of power/track times are you making now?

I'd go with a fuel system for sure

SuperZ

I havnt ran it yet.It makes 600 to 650 depending on how much boost it is running on the dyno.

what injectors and pump do you have now?

motron 60s and just a racetronix255 with harness.

Well, you are at least giving me confidence that my racetronix pump/harness will hold 525 rwhp.

I made 530rwhp on 9psi on a real rich A/F 9.9

smokinHawk

iTrader: (48)

if you have a boost reference regualtor you should be able to get 600rwhp out of that pump.
anymore id be looking into a second or bigger pump.

so should I go twin Inline Walbro GSS392s or single A1000

id think about sumping your tank or just running two walbros intank.

Hey man.. I love your setup.. followed the build and watched the video of the first run several times while buildign mine...

my thoughts on the matter after having numerous twin intank issues with my walbros.. I drained and drilled the tank and used a -12an bulkhead fitting cut to length at the top of the retaining nut inside the tank and used some "Seal All" then hooked up an A1000 and a billet fuel pump controller. this was by far the wisest thing I could have done affordably to rid myself of the issues with the walbros. two pumps to me now mentally equates to twice the problems.. I almost lost my motor after having a pump failure, then again when one of the lines came off the top of the pump where the little insert is which remained inside the line that was clamped.. and make note that using a 1:1 regulator almost always assures a problem like that happening when pressures are elevated under boost.. that cured me of the twin intank setups for good.

anyways.. reporting on the A1000.. was affraid it would be obnoxiously loud, but it really isn't too bad at all. with the sumped tanks available for you guys, it would be a no brainer to me to go with a larger pump, rather the A1000 or the new magnafuel pump or a weldon.. eventually you will wish you had to start with.

ps with 8.7 scr aren'tt he 6L heads gonna drop that down a good bit more?

SuperZ

yeah it would prolly drop it down to close to 8:1 comp.I was looking at the speed inc kits and wondering wich one would be good for me

-All necessary braided lines and fittings
stage 2
-(2) Inline Walbro GSS392 Pumps
-(2) Fuel Filters
