Like the title says.
First thing is after the new bracket was installed the belt is touching from the waterpump to the tension against itself. I am refering to the main belt not the blower belt.

Now the other problem. Thecar ran great beforethe vortech sq trim 6-8 psi kit was installed. I changed the injectors, and maf along witht he kit. I didnt use the fmu, or the msd boost redtard box, or the t-rex inline pump. eNow here is what happens the car starts and idles fine but start to run "rough" at about 2200-2500 r's to full throttle. It als most sounds like plugs arent in correct sequence (firing order) but has been checked a few times. Timing is set at 14 deg.

Also some other notes is that fuel pressure is set at 38 psi and when I take vacum off it doesnt drop at all it is the same. Also when car is shut off the fuel pressure starts to bleed off until there is zero pressure. My old setup would hold pressure for hours.

Thanks in advance for helping me.

I am just shooting in the dark...others with blown experience will chime in I am sure, but did you change your plug gap? I think with a blower you have to go from a .050 gap to more like a .035 gap. That might be why you run rough at highr RPMS...you are blowing out spark.

As far as fuel pressure, mine will bleed down...always had.

As far as the belt issue, a picture would help.

I hate to say this but you did a half *** install....what injectors did you use? the FMu IS NEED WITH A 19 OR 24# injectors for 8 psi..and are you using a stock pump? and the inline t-rex is a must....let that intank fail once you'll learn all too late it was needed.. also you have too much timing 10 degrees is all is needed

didnt change my plug gap i will try that....


i am using y 38lb injectors with a prom 80.... i was told by kennedys dynotune not to use the t-rex to just use a 255 lph intank pump. And I will turn down the timing to 10 deg

I use 2 pumps in all s/c and nitrous apps remember it's your engine take precautions

ok thanks for the heads up... Kwik could it have anything to do with not using the msd btm boost retard box?

I use a timing retard option on my crane...it's needed to wart off denotation to a small point

I had a friend with a vortech supercharger and he had to relocate his alternator to under the supercharger, beside the smog pump
