Flames
Hello my fellow Porsche friends,
Just a quick question. I realised that my car throws flames much more usually on a warmer day. It was raining all day here and I was taking a nice cool drive back home when I decided to floor it(the adrenalin bug). Usually my car would shoot flames bright enough for me to see the reflection bounce of the wall or from my side mirrors. However as it was raining today, I hardly saw any flames when I let of the throttle like before.
Isit because of the cooler weather and the rain and the engine temp is not as warm as the other days? Off course my engine was properly warmed up. Pardon my ignorance but I just need to know. Thanks.

Two shots in the dark:
-denser air mean that you could run a little leaner with less built up gas then in the exhaust
-could you have cooled the exhaust just prior due to water spray off the road
I only see it at the race track on mine, so no personal experience

LukeSportsman,
I would think your correct. I guess I would have cooled the exhaust just prior due to water spray of from the rain/road. Otherwise on normal weather it's a fire breathing dragon.

Sameer,
My oil temps are barely driveable on the cold days up here. It barely gets to the first white line (170F) but wont go over no matter how hard I try.
It definitely has more power than a warm day though, feels like 30 horse - can't wait to get this thing intercooled.

All's under control guys. Went out today for a short burst on the freeway and floored it again. No rain whatsoever just like the other days. Car threw big flames as per normal. I guess it was the rain that killed the flames the other day.

Speaking of flames, I've been wondering if they are unique to the CIS engines? Will a motronic engine (ala C2Turbo) also spit flames if set up with a free-flow exhaust, headers, and no cat?

930 wannabee, my 951 shoots flames. There's also a great video out on the internet somewhere of a Supra MKIV Turbo that shoots giant fireball flames as well. Anytime you run that rich with a very hot exhaust and/or turbo and have nothing to stop the flames from easily getting out (like a cat), you will get flames.
I've seen kits that put a spark plug in your tailpipe to ignite your spent gasses as well for the ricer crowd....hehe
