Howdy, I figured I'd post a couple vids of my Firehawk in action. I'm relatively new to track driving as this is only my second year doing road course stuff. I'm not a total newbie though as I've done some drag racing and autox in the past. Does Gran Turismo count as seat time? just kidding...

Pocono North/South course (typical TNiA layout) - 1:45.56 best so far

NJMP Thunderbolt - 1:36.75 best so far, although I feel I could definitely shave more time off at an event with less traffic

NJMP Lightning - 1:16.56 best so far, hanging with a SS 1LE and a C7

and 1:18.44 from last month https://www.youtube.com/watch?v=RQhoC0jkFtE

I'm working on getting a tow rig so I can make it to farther tracks next year. Summit Point, Glen, Pitt, etc.

Specs:
95 Firehawk
Stock SLP Bilsteins
UMI/BMR springs f/r
Hellwig 35mm front sway
Founders LCAs, Founders panhard, UMI torque arm
GW front upper A-arms
Kenny Brown subframe connectors
CTSV1 brakes and no ABS
Headers, a glasspack, and 1.7 roller rockers are the only power mods
18x10.5 C5z wheels with 315 Falken RT615k+ tires

I used a similar setup on my "72 Corvette race car (ex-GT1). I too blocked off the by-pass on my oil filter adapter to ensure all the oil went through the filter before going to the rest of the engine. My oil pump was the stock Chevy Z-28 performance model. The only real difference between our setups is I used an external oil temp sensor. The Setrab remote oil thermostat remained closed forcing the oil to by-pass the oil cooler until the oil had reach a temperature of 180F. Then the oil was routed through the oil cooler.

I'll have to look up the Derale setup because I'm not familiar with it's operation. I'm partial to Mobil 1 oil filters, but your Duramax should work fine with your setup.

What oil weights are you using , and how much oil does your setup hold? I used six quarts of Red Line 10W-30 for a while then switched to 15W-50 after I installed an oil temperature gauge. With the 15W50 oil, I would peg the oil pressure gauge immediately after start up. When the oil pressure got down to 45 psi at idle, I knew it was okay to drive/race the Vette.

Is there some way that you can determine is your thermostatic switch is working properly?
