I'm looking to get a fuel system for my 92. I'm looking in to a airdog , anyone know a good company to deal with on that and what size you all believe would be best for what im wanting to run. Injector wise, this spring im dropping bigger injectors in, I was thinking 5x14s but wasn't for sure and looking for more advice. My setup right now is Denny fuel pin, 3200 gov spring , full cut delivery valves, advanced timing, hx35 turbo, 4 in. Straight turbo back exhaust, gauges and pump tuning. This spring/summer i plan to p pump it then later on put a bigger turbo, possibly twins, and cam. Any help would be appreciated or advice on injectors and fuel system.

 

I'd get some 7x.014's

 

How much of a difference would there be? Opinion on 5x16s?

 

a stock injector has a cross section of about .00354
5x14's are .000769
5x16's are .001005
7x14's are .001077

the later 2 cross section are right at 3 times larger than a stock injector

if you are planning on running the hx35 or anything close to its size in an s300 chassis i would stick with the 5x14's or 5x12's for that matter. if you are after lots-o-power and a set of compounds or a big single then its up to you and how much smoke you like to see.

a 435hp marine injector is a 5x14

 

fuel systems arent really necessary on 12 valves.

 

Where did you find those and how much?

 

What you did there, I see it

 

Scheid has some...ish....they'll flow more (supposedly) but I think they're keeping them for the 14mm pumps they build.

 

Yes they are, the diaphragm pumps cant hold up. You need a good electric pump Keep it regulated to around 15psi or so.

 

And the fuel system will drain your fuel. Just letting you know
