Exhaust!! On S10 drag truck!!
 

Ok I was at the drag strip Saturday and there was an S10 drag truck has a Lavender race engine in it (local engine builders) and when it went by me I felt the exhaust hit my leg and noticed it wasn't hot like most exhaust it had ran for a couple hours by then and when it came back to the pits I went up to it and felt it again while they were doing some tuning on it never asked them why the exhaust was like that but wish I had!! Anybody knows what causes this? It wasn't hot nor cold more of a coldish warm but after running as much and fast as this engine does it should be hot as hell shouldn't it?

He probably was running on alcohol would be my guess.

Yea I didn't know never seen any other drag cars/trucks do that!!!
