How can i increase the boost on the pes supercharger on a 98 a6??

Bollinger

That gets more revs and more boost. Then you need to adjust the waste gate if it has one.

If you don't have a G2 supercharger, I wouldn't even consider it. You're going to have to go to higher octane gas to stop the knocking.

but on the same hand, you may need different software to accomodate more fuel for the increased boost, and you take a chance in pre-ignition, etc. I would NOT recommend it. I've talked to PES and they are seeing if GIAC will make a chip for the current setup that will allow use of 100 octane fuel but allow a bit more power (ie more timing)

What if you used water injection to control the detonation? you would not have to run as rich a fuel mixture.<ul><li><a href="http://aquamist.co.uk">http://aquamist.co.uk</a</li></ul>

As Rob and I know the first PES G2 kits did make more boost. So if you wanted to get frisky, you could use the smaller pulley from an early G2 and the chip that came with it at that time.

Of course, there was a *reason* PES dropped the boost and sent out new pulleys to all of us early adopters. Too much boost, high compression engine, octane level of fuel a little low for whatever reason, and ping-ping-pop.

I never had any problems in the old configuation, never pinged once. So I was kind of slow in putting the bigger pulley on. However, even though they lowered the boost, the car if anything is running better. Chip tuning improved so even with the lower boost, you make 295.

I'm with Rob. If all you do is put a smaller pulley there you are going to have trouble. If you try to up boost and just put in bigger injectors, with flow rates higher by the ratio of the boost increase, you'll still have trouble with timing. Or the need to alter that rising rate FPR. Can't get away from needing to change the chip, I think. And for that you'd need PES/GAIC to help.

What would you people recommend for more power?? I already have a chip and remus exhaust.

if you want more power use water injection...

Bollinger

What water injection does:
Allow you to run lower octane fuel or more timing advance on the same octane.
What water injection doesn't do:
Give you more power or allow you to run other than stoichastic mixtures efficiently.

If if you were to do this mod you would want to get it working on 100 Octane gas first. Then, if that works, try to add the water injection and see if you can make it work the same on 91 or 94 octane.

Honestly, it isn't going to work as well as you would like.

I have set cars up on 91 octane with water injection and the run 87 octane with out detonation. It does work. As you say though high octane fuel is always a good start.
