Runs cooler
Posted: Sat Sep 23, 2006 7:46 am
Ok, so Ive had the extractors and 2.5 inch mandrel bent system on the swb GQ for two weeks now.
I remember reading from here that extractors tends to send the under bonnet heat higher.
Well I can say for a fact that mine has done the complete oppossite. It runs much cooler!
And cools down (after switch off) much sooner as well. I found this out yesterday when I did my valve clearances. Far less residual heat from the extractors as oppossed to the OE cast exhaust manifold.
