Best way to lower Temperatures?

[Balzac]

I have a 95 auto, #5 TST, gov. spring kit and boost @ 35psi.

While pulling my 12000# 5th Wheel, my temps, both egt and engine temps rise fast and high. I am just changing to 4" turbo back. What will give me the next best lower temps?

Thanks for the help, this forum is great.

Turbo

16cm turbo housing or HX40 turbo. I need to do something with my turbo at some point. I'm leaning towards a PDR HX35 16cm but that may be too small for future bombing, I don't know. I'm sure someone with a lot more knowledge will chime in here.

Well ... soapbox dragging out ... HX40 would be my vote. Not taking away from SOTN's HX35, but I'd get his HX40-16. I totally agree CumminsPower98, the HX40 has more bandwidth. I tow with the stock configuration HX40-16 & am happy with it's spool up & reduction in EGT over the HX35. I don't remember exactly how much it reduced EGT, but it was a bunch.



A plate that got me 1500 degrees in the center position with the HX35, got me 1300 degrees 3/4 of the way forward with the HX40.



By the way, lag & EGT can be reduced further with a good air filter. I'm using the BHAF, which reduced lag noticeably and EGT by another 50 degrees. The lag reduction just told me that the stock airbox can't hack the mission with BOMB'ed air flow levels.



Hope this helps. Oo.
