I just went with 8 SVO injectors. But you're running a blower too.

How much boost?

Just a thought.... a 3.5% variation on injector flow can alter A/F ratio on that cylinder by 0.5 A/F units. On an NA setup, you would lose some power, but probably do no damage. On a major power adder, leaning out by 0.5 A/F units could cost you a piston. Or, you will see signs of detonation on that plug when you are tuning, and have to richen up the mixture to protect the engine, losing power on the other 7 cylinders..... unless you have a setup that can tune fuel and/or timing on an individual cylinder basis.

3.5%? Is that the variation??? DIdn't know it was that much.. I thought it was ± 0.1 #...

I see the point... so its an extra insurance...

I'm just throwing out numbers..... I had a set of stock RP injectors cleaned and flow matched by TPIS, and at least one of them had a serious problem, and had to be replaced. It flowed way low.

What kind of injectors are you buying? I thought when I dropped $200 on a set of SVO's from IRS a few years ago, that they were advertised as "flow matched"??????
