Hardluck33 Posted March 7, 2009 Report Share Posted March 7, 2009 I have driven the car about 100 miles since the S/C mod and I noticed today there is a ton of carbon in the exhaust pipes already...any ideas or is this normal? Link to comment Share on other sites More sharing options...
Red Diver Posted March 7, 2009 Report Share Posted March 7, 2009 Wish I knew, I have about 1000 miles on my KBSC, no carbon in the tail pipes. GOOD LUCK!!! Link to comment Share on other sites More sharing options...
Hardluck33 Posted March 7, 2009 Author Report Share Posted March 7, 2009 Well never mind, I should have written Dennis right away, but did not want to bug him. As usual an immediate email response. Less than 30 seconds after my question---"absolutely normal, not too rich" Link to comment Share on other sites More sharing options...

Dig-It Posted March 8, 2009 Report Share Posted March 8, 2009 Jason, I'm sure the tune from Whipple is on the conservative side of the air/fuel ratio and therefor a bit rich to keep the combustion relatively cool, but I don't think you should have "a ton of of carbon" in the exhaust. Watch the A/F ratio like a hawk at the Carolina dyno day you're going to at the end of the month - especially at 4800 rpm where it slipped on the dyno at Tasca. You're in the Army, you know, "Trust, but verify" We need some Whipple owners to chime in here and help Jason out! So far only three KB owners have replied.

I will drive the car to work tomorrow again and check the tail pipes at the end of the day. Jason Link to comment Share on other sites More sharing options...
Dunedindon#5481 Posted March 8, 2009 Report Share Posted March 8, 2009 Guys, I have residue in my exhaust tips every time I drive it. I had it dyoed the other day and they told me that is was running a bit rich with the FRPP tune but that was OK because it help compensate for the 10% Ethanol that we have in our gas around here. I pretty much just wipe it off after any spirited drive. I guess I'd rather have it running a bit rich than lean. Don Link to comment Share on other sites More sharing options...
shel-b001 Posted March 8, 2009 Report Share Posted March 8, 2009 A little rich is good for sure. I wonder if Wipple & Kenny Bell both do this in the tunes because of the ethanol. Link to comment Share on other sites More sharing options...
Radical08 Posted March 8, 2009 Report Share Posted March 8, 2009 I have a Whipple on my 08 and have no carbon build up. I see the slighest amount of carbon when warming up that is there with the gas condensate, but no build up and nothing after warm. No black smoke coming out if I get in it. I watch the fuel gage go from 40psi to 75psi when you get in it but all normal. The tune from FRPP via Whipple is a bit rich to be on the safe side. Mine dips down rich when first gotten in to but comes back up a bit (still rich). I asked FRPP about it and Whipple and they said that is normal. I would think a build up of carbon is not normal. I would check my plugs also to see what's on them. Now my kit is also basically a 2007 type with open filter, so not sure what if any that has to do with it and doubtful anything from all the testing they did. FRPP and Whipple stated they had no failures of engines with the kits and tune as supplied. The intercooled kit is either 10 or 11psi boost. Go above that or modify the tune to lean it out for more power and you're own your own. Only true way to see what the deal is, would be to install a wide band F/A monitor to see or take it in for analysis at a tune shop. Sniffing the tail pipe will not be true F/A readings like most dyno's use and have to use unless you had a bung in the pipes for tapping in to get real readings.
