If the picture is correct these are the Bosch/Delphi injectors used in the Buick V6 3800SC motor.

43.5PSI and they quote +/- 1% which is a 2% spread.

Thanks this has been an informative thread especially considering the fact that I was running lean on 2 cylinders. Flow matched it is.

whats the ammount of HP a 30 # injector would support? I read someplace on about nitrous a 36 # injector would be more the injector to use, say to support 5-700hp, or does a 30 # injector do about the same?

They aren't all created equal like injectors lol.

This is sort of closure to this thread. As mentioned above, TSP offers 30# SVO injectors both flow matched and not for $300 and $220 respectively. I went for the flow matched as I do intend to tune near the edge. They arrived in a Ford Racing box with a card that reads:

Ford Racing
Part # M9593-B302F
Group # 199
Flow Rate
31.12
31.13
31.13
31.14
31.14
31.15
31.16
31.16

That is 31.14 +/- 0.02, which is pretty damn good, less than +/- 0.1% difference.

Racetronix-
Thanks for bringing this back from the dead. Very interesting. I see a Racetronix fuel pump and 8 matched injectors in my future.

After scrolling through a very informative thread I am in question about my new set-up and what INJECTOR to use (2003 Z06, FAST 90, Electric WP, Full-boltons, and the TSP MS3 cam). Don't plan on using any power adders

Would 30lb SVO injectors work ($199 from a vendor) or just get the flowed ones for $300.

Does it matter with my application?

It seems like I went over-kill on everything for this new set-up.

Thanks,

Bill

Just get the cheaper ones.

No reason for over-kill on injectors. The only reason to get the flow matched ones is if you are a hard core racer looking for every last horse. Or if you have money to burn.

An injector at the opposite end of the tolerance scale can create chronic knock problems and prevent anybody from reaching the max HP level no matter what go fast goodies one has added to their motor. Most disc injectors and EV6 Bosch injectors have much better than average tolerances as a percentage when compared to older types of injectors.

Racetronics, What do I need.

Just read this long thread. I have a stock cube LS1, stage II 5.3 heads (10.6 compression), custom longtube step header 1 3/4 to 1 7/8. Fast 90 intake and tb. Cam is 230-230 .596 .598 lift on a 110 lsa. Motor is in a 69 camaro with a T56. No numbers yet as car is not finished, but thinking 430 to 450 rwhp with a redline in the 6700 rpm range. Running an Areomotive A1000 pump and regulator with high flow billet fuel rails. What injector would you rec for this set-up and where to purchase.

I also have a T-N-T wet shot kit but it should not have any bearing on the injector selection should it?

Thanks for your help

Payton
