Just wondering what people are seeing for EGTs when doing a 1/4 mile pass, with any of the various S475 basic twin kits. I am going tonight and would like some EGT numbers to compare to from people with similar setups.
You wont be looking at them anyway, and even if you were its not like youre going to let out of it

Oh trust me I know! Went Sunday and barely looked, and certainly I am not going to let out of it. I am just concerned that I may have a small boost leak, and I figured EGT would be a good thing to monitor to determine that. I hold about 51 psi boost, but my EGTs have been in the 1500s. I have pressurized the system to 20psi or so and no leaks, any more than that and the PVC cap blows off, so can't really test to a higher PSI. My times were 12.7 @ 107mph with a 1.9 60'. 60' could have been better, but is that about what MPH you guys are seeing?
how much boost is the big turbo making?
51 psi
thats your combined. i want to know what the atmopheric turbo (the 475) is making before your stock turbo pressurizes that air as well
Ok, I am not sure on that, I do not have a boost gauge monitoring prior to the stock turbo.
Who is tuning it?
I'm doing 112-113 mph on street tires.
I have a steady 47-48 psi till 3rd gear than shifting to 4th is about 52-53 and shifting to 5th is 56-57.
Those are spike during shifting.
Mine stay under 1500* no matter what. 60+#'s(gauge stops at 60). High rpm's will cause high egt's too.
