I'll be installing my Comptech supercharger this weekend. But I'm from a pretty small town and don't think there are many dyno options in Grand Junction with a wideband. My question is, I go to school in Fort Collins and I'll be on spring break all next week. Would there be any devastating consequences to drive the car back to Ft. Collins (300 miles) without the belt, to get the car tuned up here? Or if anyone has any recommendations on what the fuel pressure should be set on the FMU for the stock 5.5lb pulley, to get me safely over to Fort Collins.

TIA

what engine management system are you using? if you are running stock injectors just keep the revs low and don't load the engine and you'll make it just fine. Keep in mind you're only boosting 5.5psi at redline.

 

I'll be just running the Stock ECU with the comptech ESM. I plan on switching out to an AEM this summer.

Basically just a stock bolt on Comptech kit.

 

You should be fine WITH the belt on. Just dont do any freeway bombing.

 

yeah, just baby it to your tuner...just make sure to drive the car after your install and then check for any leaks before you start your 300 miles trek. but definetely keep the belt on.

 

Thanks for the help guys. I'm pretty sure I can probably get the FMU close enough not to damage anything, but I figured it would be worth asking.

 

as long as you do not enter boost, you should be fine.

 

You can drive the car without the belt no problem, just know that it won't feel quite the same as it has to pull air in past the SC that isn't spinning.

 

iv been running mine without the sc belt on because when i bought the car it had the sc on it already with no ESM so i am waiting to get my emanage blue put in and change my map voltagen. I have no problems except explaining to people when they go ooooo sweet supercharged hows it pull.

 

I must be stupid tonight. I re-read this 3x! If this is a stock Comptech kit with the Comptech supplied FPR, what exactly are you going to have tuned? There's no need unless the kit is used and the FPR has been altered or adjusted in some way.

Since the stock kit relies entirely an ESM to mask boost and a FPR to push more fuel, the only adjustment available is more or less fuel pressure.

If I'm not understanding and you aren't going with a fuel delivery setup that is standard for the kit, I would not run the belt. Why "guess" at what fuel pressure should be for 300 miles? When I was at stock boost, fuel pressure at the rail varied from 35-40psi at idle to easily over 80psi at rpm. Again, if this isn't a standard kit in some way, then install it, drive and hope for the best seems like a bad idea....if it is a standard kit the trip to the tuner is optional. Not a bad idea for a double check of A/F's but not necessary.
