My best run turned out to be 169.384 MPH - I missed out on the best weather on day 2 - but I still had a great time.
The SRT6 held up fine and surprised a lot of people (but we know that).
Next year I'll go with some drag radials, remove all four cats and muffler, get a 100 Octane tune (I didn't have time this year due to the fender-bender) and I think I could run in the 180's (Vette territory)
Some notes:
The biggest factor mechanically was when the transmission was shifting from 4th to 5th at redline. (this happens around the 3/4 mile mark) The RPM drop off was far more then the other shifts and at these speeds - the last 1/4 mile just zips by - just not enough time recover.
Engine RPM was approx 5,400 in 5th gear at the mile mark.
Speedometer was indicating over 170MPH on my fastest runs (165+ MPH) - not sure if thats just error or where they place the speed gun.
Hottest IAT reading I saw was 163*F on first day when it was 90* outside
On day two and three I never registered above 145* F and always cooled down to under 100* F between runs (45 min to 90 mins)

I think my tires are only rated to 168mph though.

Do you log your IATs with the stock sensor and OBD2? Thanks.

I think my tires are only rated to 168mph though.I would just pop the hood in the staging lanes and let the wind cool the SC down; was cool to the touch before launcing - seemed to work good enough.

Thanks.

The heat wrap I installed around my intercooler really paid off. It keeps the surrounding heat from the SC and engine block from "soaking" it allowing for quick recovery along with having the Johnson pump wired to the ignition switch. I can open the flow tank and dip my finger into the coolant at anytime.
I also separated the HE cooling system from the engine and built a custom "flow" tank for the intercooler when I installed the larger LET Heat Exchanger.
I think I'm going to work on a few more "cooling mods" over the next few months.

Some people told me maybe this would work better than cover the whole IC with aluminum foil? What's your opinion about this?
Thanks.
Thanks.
If you want, I can send you some - I have a ton left over.
