Go with the Siemens 57 pounders, I've heard they are much easier to tune than the 50's, and thats the highest you can go w/out converting....

well, I already have the 50's in the car, Ive been running them for a while now. They seem to be ok. But I was hoping to keep these till I get my FAST system, then go to some big boys!!

Yea I have a similar plan as well, my 42.5's are doing just fine with a CAS regulator and a hot wire kit....

But in the future it will be a FAST system and 83's most likely....

What about the Speed Inc impedance converter? How good is that? It looks way cheaper than going to a FAST setup.

A guy in my car club (who posts here) made 600 rwhp with 42 lb bosch injectors with an intank walbro pump and a rising rate regulator from the 97 vette. The rising rate makes a big difference.

The Speed Inc. converter is good for bigger injectors, but when you make enough HP you eventually have to step up to a different fuel management system, like FAST...

smokin,

Is he using the intank pump that came with the Incon kit, or is he using a in-line pump as well?

Thanks

How does the fast system work with the existing PCM as far as timing and other aspects?

I'm running 55lb/hr injectors on the stock PCM and a custom fuel system (sumped tank, monster aeromotive pump, regulator, fuel-rails, feed/return lines etc).

I'll be installing the impedance box in the next few months to see what I can do on the stock PCM...

The FAST controls the fuel, and LS1 edit is used to control the timing...

he is using the reglator that came with it, i think he is using a walbor intank but not 100% sure, stock lines and rails too., but he says FP starts to drop off so that seems about the limit.
