Stock injectors

PDYoung · September 29, 2012

Does anybody know what lbs. injectors are in these L9H motors? Running 11lbs of boost on E-Force now stock injectors are maxing out,time to go up in size,just don't know what size the stock ones are.

how's that hot rod working out for you PDYoung? Did you swap out the throttle body or stick with the 87mm?

Hey Jonathan how have you and the SC540 been doing. I went with the 90mm throttle body and didn't feel much of anything or notice too much difference.i took my truck to the track with the added E-Force and the 90mm and was really disappointed with an almost stock run of 14.16 @ 96mph.So i added a set ok Kooks 1 7/8 headers and took it and had it tuned. After the tune i started feeling better,like i just didn't spend 8k for hardly nothing.I went back to the track after the tune and made one pass. That one pass got me a 13.20 @ 103. The tuner told me that my injectors were running flat out,so now i've bought a set of Boush EV 14 60lb. I just don't know how i'm going to put the new injectors in and get it tuned.I'm being told the truck will not run with the new injectors and the tune i have in now How do i put injectors in and get it to the tuner,tow it ? I also have a nice cam,springs and titantium retainers ready to go in also,but the guy who tuned my truck is talking me out of it.He said he has done cam swaps for these camaro guys and they hate it,he says they tell him if they had to do it again they would choose not to.He says they complain about losing their driveabilty and their gas milage just went south.Other than that,the truck feels real strong.I had a 1.8 60ft time launching like you told me.Auto on the four wheel selector with traction control off.Launchs like a neck snapper .

Thanks for asking,

Paul

Sounds like it's coming along nicely. Did you do a dyno run yet? Curious what that beast is pushing out. On the injector/tuner bit I would consider an AutoCal from Black Bear Performance. Otherwise take your tools and drive over to your tuner's shop and start swapping them out. Beats paying for a tow. Maybe he's got some room at his shop for you to do the swap.?. Also consider putting it in 4WD HI on your next launch. I felt mine start in 2WD and clunk in to 4WD one time when I wasn't full throttle (thank goodness) when I had it in auto so now I launch already in 4WD so that it doesn't slam it in when I hit it. Did Edelbrock suggest the 60lb injectors? Not sure what mine are but I know that was part of the Callaway upgrade. Glad to hear that your hot rod is doing you right. If you're not sure about the cam, or injectors or anything else LS related pm justin at blackbear, he is an LS motor guru and has done alot of them with superchargers, cams, headers, you name it. He is a sponsor on here and would be glad to help. He may even read this and pm you if he sees it. How about some more pics?

Talk to you soon,

Jonathan
