Ok guys I need some advice, more like mentoring. I recently just bought a LS1Camaro with a procharger. Its got autometer gauges already set up. Its also got a scanmaster. What should the gauges read as I am driving. What advice could you give to keep the charger working propelry like maintaince. Thanks in advance.

Check on prochargers website. You need to change the oil in the head unit every 6K miles or so. What's the rest of the combo?

Not really much of a combo left to talk about I guess. It's got a F1A with about 6 to 7 PSI. Twin intercooled. I picked it up and drove 150+ miles with none of the gauges changing. Temp was 210. 40 on oil pressure. 20 on vacuum. 60 on the fuel. The voltage did go down all the way to 032. No clue what that means. Dyno sheet I got said it had 509 at the wheels on 10 PSI.

6 to 7 psi with an F-1A is exceptionally low. Check for belt dust on the blower, which would indicate excessive belt slippage. Make sure the air filter is clean, a dirty air filter causes a lot of restriction on forced induction cars and will lower the boost produced. Bob

Thanks alot Bob that's the stuff I wanted to hear. I will definetly monitor for that. Silly question but how would I turn up the boost on it. It's got a five inch pulley I believe which i was told is the biggest one to put on it.

You need a smaller pulley to make more boost, silly.

Lmao that's how new I am. I ll get to you're guys level someday....

Forged motor? Are the gauges hooked up?

4kiro

Stock motor. Yes they are all hooked up. it's got a scanmastet hooked up too but not really know what it does other than read the volts and the timing retard.

Other then pulling that procharger off and installing a turbo...sarcasm!!! Make sure you pay attention to the wideband when racing or making some pulls. This helps to make sure everything is up to par.

4kiro

Lol. Sux cause no one close to me runs prochargers so there no one I could talk to about this stuff. Wideband? Is that the scanmaster, what is bad are the danger areas. Was thinking about getting a air fuel ratio gauge. Should I. Also the car is tuned for the smaller pulley but I have been using the bigger one. Should I change that?

You aren't going to want to run too much boost with a stock motor so I'd keep the pulley the same. I'd personally keep it around 5-7psi on a stock bottom end motor.

4kiro

You think I need to retune it for the lower psi? Just noticed the is alot of belt dust on the head unit. Belt feels really loose. How do I know when the belt is tight enough. Think I am going to replace the belt.

What bracket is it? The belt needs to be pretty darn tight. The regular procharger J brackets have a hard time keeping the belts from slipping.

Sweet_SS

Wideband is NOT a scan master. As far as the A/F gauge goes....that's just a light show. Do you like blinking lights? A/F gauges are narrow band and are not as accurate as a wideband. I would if I were you, get a wideband asap. If that car leans out at all....could spell disaster. Do a search on Tech and get the right one that suites you. I went with the AEM UEGO wideband.

4kiro

Thank you will do. Last thing I want is to be cheap on something small and blow the thing up.

AEM UEGO here as well. You should run a wideband and a fuel pressure gauge at least. Those two gauges can save your ***...they've sure as hell saved mine a couple of times lol

4kiro

Well it's got a boost and vacuum on one gauge and the fuel pressure on the other.

I'd put a new blower belt on it, and take it easy on the belt for around an hour of driving time to break it in, then tighten it back down again. The belt needs to be about as tight as a guitar string to keep it from slipping. On engines with stock bottom ends, I like to keep the boost around 8 psi. As long as the engine got a good tune for the ProCharger, you should not have any problems with it. For a 5.00 pulley and the 8 rib 7.65 crank pulley, you would need an 8 rib belt that is 41.50" long. You should be able to pick one up at your local Napa.

As for air/fuel ratio gauges go, the standard air/fuel gauges that are around $50.00 or so are nothing more than a light show. The wide band that has been mentioned is an air/fuel gauge too, but it is the type that is needed to really tell where the air/fuel ratio is at. A wide band requires putting a bung into the header collector and installing the supplied wideband 02 sensor into the collector. Bob

Thank you Bob really appreciate the information.
