2008 SOS Upgrade Thread
Oh man looks like I'm back to the drawing board hey u guys have lost me lol! I will ask my tuner about all the technical stuff I know I'm running a haltech platinum sport 1000. He said theres a fair but of room injector wise, umm as far as the fittings go I have no idea I will have to work it out. I got myechanoc to fit all the fuel side of things so I can't really say.

What injectors are you running? My car made an easy 389whp by 6500rpm and the pump started to loose constant flow. I'm putting an order in for the fb dual hanger with 2 fb340 pumps will my 1000cc injectors keep up?
9.5:1 comp built engine
3.2" SOS pulley (made 20.5 psi on e85)
1200blower.
Fpr is set at 40psi which I think is too low anyway.
Let me know what u guys think.

- You are running lower compression & higher boost than most of us do on stock compression & pump gas. So you need more fuel, and yeah I'd start to wonder if ID1000's might become a limiting factor. (At normal fuel pressure levels. When people say you need bigger injectors, that means they are assuming you are keeping stock fuel pressure levels.)
- 40psi sounds lower than stock, so that's the first thing I'd fix before swapping injectors. (Isn't 47psi the stock fuel pressure?)
- You can increase the fuel pressure and get more fuel into the motor regardless of the injectors you're using. Essentially, you can either increase the size of the hole the fuel flows through (injector size) or increase the pressure forcing the fuel through the hole (fuel pressure). Either (or both) will get more fuel into the engine. Many of us choose to just swap injectors, but with a low compression / high boost build you might be in a position where running higher fuel pressure makes sense.
- There are good calculators you can use to determine what size injectors you need for a given HP level, fuel type, and fuel pressure. Take a look at the RC Engineering website, and the Injector Dynamics website. You can play around to see what's needed to achieve your HP target.
