1:18.32 at MSR CCW 1.7 with Crap Conditions, Stock Tires
Did some testing at MSR this weekend with the help of Adam (SilveradoSS500) and Louis at GSpeed.
Were testing the DeWitts C7 Kit, (more on that on another post.)
Louis and the guys a GSpeed did an outstanding job, kudos!
Adam has a lot of laps at MSR, and it shows. This guy is one hot shoe, if your on the track with him, just give him some room.
Could not have gotten the results without his help, thanks Adam!
I wanted to post this, in recognition of his talent in-spite of the conditions.
Rained the night before, a bit misty in the morning, and a stream of water crossing the track just before braking zone.
Based on this data, the water handicapped sector one by 1.66 seconds, therefor the car was basically two seconds faster then Adams 1:18.7 lap in his car, Adam tells me he can do a high 1:15 or low 1:16 on stock tires.
Adam may chime in Ill let him answer any questions if you have any.
Here is two videos, one is the PDR, other is off of Adams GoPro of same lap.
That is getting with the program. What were temps and lap times at end of session?
We had some throttle issues at first but squeezed off that 1:18.32. The pace was basically a 1:16.50 based on losing 2 seconds in sector 1 because of the standing water. Watch my little bend entry, I gained 1.66 in that brake zone or not sure if I would call that a brake zone ha.
Based on what I did in Little Bend, I bet my rattle snake entry will be insane, who knows, it could be a high 1:15.XX with the right track conditions.

For those that may be interested we tested the DeWitt's Oil Cooler, it did a nice job bringing the oil temps down.
Sunday Louis and myself pushed car to overheat, go into limp mode, etc. while we did data logging. With water in the 248 range, the oil average high was about 265deg, beats 300 for sure.
Working on a write-up on the DeWitt's C7 Cooling kit, have it up soon.

Just saw this, by the time Adam finished this lap, the temp had creeped up enough the next lap really suffered.
Interesting tidbit, at these temps, this is the timing that is pulled by computer.
195 - 1deg
212 - 3deg
230 - 5deg
248 - 6deg
Notice the low water temp of lap 2, its 228 deg. at beginning of the run, that tells us were already at least 3deg timing down starting out, by the end of lap were 241deg and were down 5+deg.
Don't know how much power loss that equates, but its defiantly noticeable.
On a car this powerful the power loss is not that big a deal, especially on a technical track. Of greater annoyance is coolant temp. At 246 by lap 4 that is really frustrating as sub 1:30 pace is 20+ laps in a session and I hate having to do cool down laps what look like every 5th lap or so. I was out last Sat and bagged it as the river was as you noticed killing lap times and banging rev limiter if you stayed in throttle. Can the car string together say 3 1:18s?
A definite step in the right direction as it was warm and humid that day. I have to think more airflow out of the hood would help and have a downforce benefit.
