Since I decided last May not to run my IPD 3"DP and the BSR program together I have been running with stock programming and the 3" DP. I've been too lazy to take the 3" DP off. My poll is, should I get off my butt and take the 3"DP off and run the BSR PPC or leave the 3"DP on. The 3"DP gives a nicer turbo sound along with a faster spool up and a little more HP , the BSR PPC gives me more HP.

Re: 3"Downpipe or BSR PPC (RhaRdeR)

I voted to leave the DP on mainly because I figure it will help with the low end grunt more. I love the BSR upgrade however, it really does increase the acceleration once you get the R in the right RPM zone.<p>But I thought you figured out that here wasn't really a detonation issue with the combo? The ideal would be both!

Re: 3"Downpipe or BSR PPC (RhaRdeR)

leave it on is my vote. I've found better gas mileage with the 3" DP + stock programming (+30 to 40 miles per tank)

who gives a S---T! about gas mileage!?? He wants to know which will help him rape a M3 and that answer is lose the dp and load the Bsr PPc. I promise you won't regret it.

I voted for both ... there are several people running the combo. I just received the BSR PPC last night and I haven't run it hard yet, but I've talked to people who have done both and haven't had a problem. Go for both!!<p>

Re: 3"Downpipe or BSR PPC (RhaRdeR)

I'd recommend some patience on your part. There are some very nice tuning solutions on the horizon (aside from BSR) that will work with your downpipe. Just be patient <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/wink.gif" BORDER="0">

I've dyno'ed my R with every combination possible and always have had detonation with the BSR and 3"DP combo except once on race gas. The A/F mixture indicate the pinging is caused by the BSR PPC program mixture really leaning out, 13.5:1 and more. How does the Aquamist system affect the air fuel mixture? <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/confused.gif" BORDER="0">

Re: 3"Downpipe or BSR PPC (RhaRdeR)

As I understand it the Aquamist system will cool the air and therefore allow more oxygen into the cylinder reducing the detonation caused by the high heat.

Re: 3"Downpipe or BSR PPC (Reno R)

I'd like to hear one of the experts give their two cents on this. Johann??? It would seem to me, more air, same fuel and it will be even leaner, hence hotter. The problem with the BSR PPC is the fact they run too lean to start with. I might be wrong on the Aquamist but it seems logical that if I put more air into the system but don't add more fuel the air/fuel ratio will get even worse. <p> Any one here know for sure?? <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/confused.gif" BORDER="0">

Maybe there are some guys on here who fly turbo-charged airplanes, it has been way too long for me to remember all of the details. If I remember correctly you lean(reduce fuel) the engine the higher you climb(thinner air). I beleive this would be the same basic concept but don't remember all of the details as it has been too long since I have flown these types of aircraft, but I do remember the same problems if the engine wasn't properly leaned.

BUT whatever, aquamist fixes that by automatically dumping water above a preset boost limit. <p>When I spoke with Scott months ago, we talked about the best ways to address this problem (if I were to run BSR) when I came florida since I couldn't get access to the 94-100 octane gas I was getting in Germany. He is the one who suggested the aquamist idea to me.
