SUPRASUZUKI Posted December 7, 2006 Share Posted December 7, 2006 Going BPU over the winter so need to get a more definitive measure of boost. (The standard gauge contains no figures). Where is it best to 't' off for the gauge pipe, closer to the turbo's or the intake manifold? Is there much of a pressure drop across the standard intercooler, or am I just flattering the technique? Cheers. Link to comment Share on other sites More sharing options...
heckler Posted December 7, 2006 Share Posted December 7, 2006 best place is off the inlet manifold Link to comment Share on other sites More sharing options...

JohnA Posted December 9, 2006 Share Posted December 9, 2006 ...Is there much of a pressure drop across the standard intercooler, It's not so much the pressure drop, as the temp difference. If you are before the IC, then air will be hotter and pressure will be higher. Link to comment Share on other sites More sharing options...
SUPRASUZUKI Posted December 9, 2006 Author Share Posted December 9, 2006 I understand that mate. Regardless of the mechanism by which the pressure drop comes about, it's still there. What I'm getting at is this - Assuming 1.2 bar as the limit of j spec turbo's. If you measure 1.2bar at the manifold, the pressure at the turbo's will be >1.2. So, logic suggests that boost should be measured (and targeted at 1.2bar) close to the turbo's, as that's the critical point to measure for turbo' life. Like I said, the delta between the two may be inconsequential as it's so small. Cheers. Link to comment Share on other sites More sharing options...
JohnA Posted December 9, 2006 Share Posted December 9, 2006 That's why the wastegate signal is traditionally taken right after the compressor. The supra is no exception. Link to comment Share on other sites More sharing options...
SUPRASUZUKI Posted December 9, 2006 Author Share Posted December 9, 2006 Yep, understand that too. Whether to measure and set at the manifold or turbo's, that is the question. When my new boost gauge comes through I'll measure both pre I/C and at the manifold, just out of interest. Link to comment Share on other sites More sharing options...
