I installed a boost/vac gauge when it was N/A and now when i installed the s/c it seems like the gauge never gets out of the vac. I only reach about 3-4K RPM so far w/ it (b/c its not tunned). Also i only drove it a few miles, basiclly b/c it runs like **** (Untunnned).

when does u guys boost gauge read boost?

Im starting to get scared i hope my s/c works

Thanks again.

 

Is the gauge hooked up right?

 

yeah i think so which vac line should it be hooked too?

I hooked it to one of the vac lines coming out of the firewall.

 

Get your car to a dyno and get it tuned before you end up looking for a new engine. Worry about your gauge later. I think you're playing with fire.

 

If you hear the supercharger spool up and you still see no boost. Your gauge is probally not hooked up right. Unfortunally I do now know where it needs to be hooked up.

 

I know im getting a custom chip made for it and hopefully i will get it in a couple of days.

when do you read boost on your gauge? no seriously.

 

Even with a custom chip, you need to get it on a dyno to check a/f (or get a Dynojet Wide Band Commander A/F gauge). If you go lean while in boost, it's game over.

I don't have a boost gauge. I wanted to spend my money on a useful gauge, so I bought the aforementioned Dynojet guage. The only thing that concerns me is seeing that needle dip below 12 when I floor it. But I believe people that have a vortech and a boost guage start to see boost at 3k. But again, you don't want to see boost right now without a tune, so test the gauge when you get one. Curiosity killed the engine, not the cat.

 

ill go out 2 test it right now. J/K

if i get a dyno tune then wuts the point of a custom chip?

 

Which vacuum source did you use to hook it up?? You should be using a vacuum source that is immediately after the Throttlebody... Just T- off one of the lines with a Vacuum T.. If you're still not getting boost, then something else is messed up...

How are you getting a "custom Chip" I assume they are gonna send it to you, after you sent them all of your specific parts you have added?

I tried to have this done, and diablo managed to set my A/F to about 15.3:1. If it isn't done with the car on hand, and the car hooked to a A/F meter, its useless.

GET to a dyno shop!
