The Guess the Numbers Game (getting tuned today)

Yes the ones in it are rated at 73lbs on my car. When i tried to tune it last time (before the new shortblock) they were at 95% duty cycle.
From what i got out of Rick, there are 2 different size LS2 style injectors, and they are about 10mm different in height. My rails are set up for the longer style, but the new injectors are the shorter style.
It is my understanding that i can just get a different set of brackets for my rails, but the problem is i don't know what rails they are. There is no markings on them at all.
I hit up Arun already to see if he can swap injectors for a longer style. Just waiting on his reply now.

An 850cc injector will flow 95lbs in a 4 bar system and that should be plenty. Your current injectors are Siemens 60 lb if they only flow 72-73 lb in your system.
Ls3 is 1/2" shorter then LS2 which is a 1/2" shorter then LS1

i think that is my current issue. I think my rails are setup for ls1, but i ordered ls2 injectors.
And yes, i think mine are 60# ls1 injectors, they have a blue ring on them.

Well finally got back on the dyno today. Car was just over 850 when the Supercharger popped.
Already talked to Doug, going to order the Paxton 2200R in the morning (damn East Coast hours) Figure i will step my game up a couple PSI while i am there.
This car has been nothing but issues since i have owned it. I have replaced every single reason i bought the car in the first place. Until today, every single thing under the hood has been replaced, except the blower, and the power steering. Any guesses on what goes next?
Going to send my 2200SL to Paxton for a rebuild, then it will be for sale as well.

i pullied the blower myself to be a few hundred RPM below max rotation. So the blower should have been fine, but i guess it was not.
When he got to the WOT runs on the dyno, i heard it all of a sudden make some F'd up noise, sounded like power steering whining. Now there is fluid coming out as well. So I am guessing blown seal and or bearings? I have no clue.
That little 2200SL was up to 17.5 psi though. I don't even know what they are rated for, but i am guessing that was about it.

Yes not sure what broke. Hit it from 60 and it free revved. It didn't make any noise, Going to find out what it is and replace it or find a c6z diff to hold me over.

Sounds like exactly what happened to me. stock 27-spline main shaft broke off inside the diff. Didn't make any noise or do anything else out of the ordinary. Just felt like it was in neutral. a C6Z diff and a 30-spline main shaft later and all was well.

Yup that sounds like it but now I'm in the market for a z06 diff.

I sincerely hope that nothing will go, of course.
