Re: injector flow 96+ s10
If you have the old style poppet injectors ('96-'01) you can get over 300 crank hp out of them with an fmu BUT they will lock up if they are spiked with fuel pressure too quickly (wot 1st gear). The newer style multec II's are true 19lb injectors and wont support anything over 280 crank hp even with over 100psi of fuel pressure.
With the poppet injectors - It took about 85psi of fuel pressure with 10psi of boost intercooled(supercharged), stock timing. With the new style multec II's I couldnt even come close to supplying enough fuel with them even with well over 100psi of fuel pressure and a bunch of timing taken out.
No one makes injectors that will fit which is why im going through the trouble of adapting a stock manifold to accept real injectors and using the multech II injector assembly to supply fuel to each injector. I have a set of shorty 44lb injectors, I'll beable to toss the fmu and use tunercat to adjust the stock ecu.
I would adapt a edelbrock 2114 for injectors but I have emissions to deal with and I dont plan on trying to get over 400hp so the stock manifold should be fine.
