RaceHorse CL65 1M @ 189 MPH & 1.5M @ 200 MPH!!!
See link for full rules: http://www.loringtiming.com
I registered for the event and read up on Exotic Metal's Texas Mile CL55 build from a few years ago. Same body, with a totally different motor, but both platforms battle heat, generating high IATs. My mods have always been pretty basic, not to take away from what the car is. I had a 6 gallon round trunk tank made to fit with or without the spare to maintain trunk space. I added a Meziere W136 up front and a Rule 2000 in tank. I wasn't looking to re-invent the wheel since it has worked for so many 55 guys. I did add valves to remove the trunk tank and run coolant for winter months thru the Mez. up front. Other Mods include a Supplemental heat exchange, Speedriven catless downpipes and Eurocharged ECU/TCU. I have also made my own intake setup off the turbos with 4" silicone fittings and rigid flex with cone filters. the stock filter setup became a choke point once the down pipes went on. A limited slip in the rear helps to get the power down.
Now the fun part. The Super Car class is limited to 1 mile and 175 MPH. They place a huge emphasis on safety. Rookies are to complete 125,150 before attempting the 175 limit.
I ended up gradually going faster, and over stepped the limits. Nothing was said as I continued to shut down after the mile. Then it was time for my last run and I was ready to leave, the last of the ice went in to top off the tank and the filters were off from a few previous runs. I went all out, just barely missing 190 MPH in the mile at 189.59 MPH. I continued to the 1.5 mark without letting up. I saw 203 MPH on the speedo!!! Then the tack dropped. I felt like the old 155 speed limiter, but everything was okay. The slip came back as 200.94 MPH! The organizers weren't all happy, but many others came up to congratulate me and take a closer look at the car. Could it have been the rev limiter at the top of 5th?

All said and done, this was one of the coolest things I have done with the car. I highly recommend it at least once. I know, a few pics or it didn't happen. I have some GO Pro footage, but its not the greatest. I'll try to add later this week.
BAD:Not the easiest to launch with no prep
GOOD: No broken parts
Looking out into no where.
Swapping stock size tires&wheels on the rear and bumping pressure up to 60PSI too much float with the 305's.. My crew just turning their back on me.
Quickest passes.
My rig on departure, I lettered up the trailer to look like a rental.

Love your crew even though they turned their back on you!!

Thank You, I'm glad you liked it, I know I certainly did.
Thank you, it surprised many. It was what I hoped for but nothing is ever a guarantee. LOL
Thanks, Now you know what you are capable of.
It was a short period of time and I was only holding it straight avoid too much movement. All in all, the weight is needed for the speed to keep it planted, the stock suspension did its job.
Thank you, maybe this is reason to hang on to yours.....They do a mile in Miami don't they??? LOL
Not knowing when I was approaching, my wife got wonderful video of the clouds, If I can figure out how to edit the GOPRO, I'll try to post something worth watching. I have footage of the last 1 mile only then the 1.5 mile, but the camera fell out of being wedged in the sunroof shade at 193 MPH I looked down when it happened. Sadly camera placement was not well thought out and should have been placed on my chest for the speedo. Maybe next time.
Hey thanks, I was very happy with the car's performance. Yes, your description of the two guys mentioned is spot on. However, I do understand tech needs to do there jobs. A mishap at these speeds is unforgiving.
Now you have also experienced the "whole capability" of these cars.
At 200,94 MPH you are still away from the rev-limiter. But maybe your speed limiter is not completely removed and was only set higher (because of tires etc)
Do you have datalogs from your run? I assume your timing was pulled because of high IATs and at these speeds when power goes down significantly it is like you step on the brakes. I have also experienced this on my car at full speed.
My current record in the SL65 is 209,40 MPH , 337 KM/H - measured with GPS on the German Autobahn.
Was your High-Speed Run done with the Grill removed like the picture on the trailer? This would cost a lot of MPH IMHO.
Always be safe at these speeds!

Hey thanks, and you are totally right, I gotta slow down, I'm gonna have to start adding more to the bucket before nothing is left.

Thanks, as long as it wasn't a moose or anything bigger than an insect, otherwise it wouldn't get spit out of the exhaust.
Hey thanks, I was told with the tuning, the limiter was totally removed. Maybe the ECU didn't like something, no CEL but the gas pedal went dead with 203 mph indicated on the center digital display, just after crossing the 1.5 mile mark. Even though, I don't do any data logging, (although I should), I know my intake temps were well maintained, based on the temp of the water in my 6 gallon trunk tank. Ice would melt after a pass but the volume of water remained cool. The best run was hot lapped, no shut down or additional ice and the car performed just fine. I ran with a very thin black mesh grill to allow the air filters better flow for the earlier runs before removing. It may have had a slight impact, but when running WOT I want a lot of air cooling the heat exchanges, radiators and tranny coolers.
There are a lot of factors which can make the ECU pull back timing or lower the boost or not let the throttle open fully - e.g. engine oil temperature, tranny oil temperature, detected knocking, exhaust temperature etc.
Nevertheless, your car runs healthy!
Let me know.. I dont think I would be willing to go much further than the NorthWest..
Thanks and great run (sorry if this is kind of a thread jack)..
