cowl rubber in or out.
over the last few days another turbo owner and I have made some temp. test,first we will use his 03 turbo 100% STOCK.
1.run the car 60 mph for 5 miles, pull over and test the temp.
the exhaust side of the turbo on top behind the intake manifold.
2.on the intake manifold.
1. 298*
2. 237*
second test was on my car, mbc set at 18 with the amxdown pipe. and with the cowl rubber removed.
1.277
2. 220
now with the rubber installed.
1. 253*
2. 185*
so what i think i found is that the air goes over the engine then the over the turbo to help cool it.
