Re: 180 tstat and intake manifold temp
Gentlemen......we did these tests last year!!! The cooler T-Stat is a PROVEN dyno tested mod performed and posted on the OC site and members on the LX site. Your overthinking this......it works.
Also, just for information....... since then, the dyno tests I did last summer, the average baseline horsepower on a Dyno Jet dyno both at GSM and Harmanmotive, for my truck were 333hp-340 depending on the configuration such as no filter, 180 degree temps, ice the manifold, first run vs 3rd run for heat soak, etc,etc. By the second or third run hp/tq starts to diminish. I had higher numbers at the XS Engineering 4 wheel DTS9000 dyno (during stock exhaust vs Mopar) but wanted to keep it apples to apples for this test so I went back to Harmans DynoJet.
Yesterday late afternoon I returned to Harmanmotives shop and wanted to test it since I had never run it with the headers/catback/ ported manifold/phenolic spacers and stock modifed cold air box as a combination......three back to back runs at 193 degrees....376hp/375tq each and every run!! Previous run at factory temps around 211-215 with stock airbox/stock exhaust was 332hp/339tq. That is a huge improvement for this combo over stock and no tune yet.
I will post those sheets tonight, all previous dyno runs are shown on the OC site under sgtstanko dyno runs. I'll run it at Irwindale Thursday to see if any improvements in times are seen.
Where is my B&G box?????
