Duel In The Desert- Kart Racing

There is no better experience than this. If I had Lawrence Stroll Money I would rather forgo formula 1 racing and race shifters instead.

It wasn't the best one, but it was a fun one for sure.I came back from p16 to p10 with a couple hard passes, but there's still room for improvement in the ra...

Weird pic for attention.
We tested the 3 most popular tires for sanctioned shifter racing:
1-MG yellow/Evinco Red (Skusa,Stars,USPKS and several others)
2-Levanto (Rok Cup USA, Sonoma, and racing in the PNW)
3-Vega XH4 (UTAH, Challenge of the Americas, Atlanta, some places in Canada)
The kart was a CompKart 30mm w/ unrestricted Iame 175. All laps were "push laps." 12.5-13 psi hot. Cold pressure started around 7-8psi. Tires were run until the the diagonal fabric overlap shown through on the tread.
Results:
Levanto-37.8 sec 70 laps
Vega-38.0 sec 50 laps
MG yel.-37.5 sec 30 laps
Notes:
I found it quite interesting that restricted vs unrestricted yielded pretty drastic differences in tire wear. Levanto and Vega are option tires. The MG is a prime tire. None of these tires had enough sidewall for the track and application we are testing on. We tested the MG option tire as well but I did not include them in these particular results, as it is not a tire commonly used for shifter. The MG option tire performed just like the vega in this test. ALL the MG tires have a narrower window of operating tire temp... too low of a temp, (like for 60cc or lo206 classes), the tire will not fire off. Get them too hot, and the tread disappears quick. I did not include the Hoosier as it is not very common in shifter racing, and its a known non-performer in the shifter class. It would likely be around ~38.0 sec and get 30 laps total. The biggest thing I'd like to point out is that the tire with the most tread depth (Levanto) was the one that seemed to be able to handle overheating the best. With the right technology, I know tires for shifter can use SIGNIFICANTLY more rubber on them without overheating problems. Even this LeVanto tire could probably handle another 1-2mm of tread depth without issues.

This is just data for "commonly raced on tires in the USA for shifter."

Data on all the prime tires tested together is coming. Stay tuned.

On May 31-June 2 Colorado Karting Tour will be hosting their 2nd round of racing at Grand Junction Motor Speedway ...a destination track for any shifter enthusiast. (see attached videos.) The racing action will always be great and last year we had 16 entries. If anyone is wanting to share transport and lodging we are driving up and staying in a local air bnb for 3 nights. The entry fee is the most affordable in the USA @ $135 total for a two day event. (no membership required.) They run a mixed shifter engine class on Evinco tires (single set) and VP fuel. The weather is always nice. Hope to see your there!

Also, the track and promoter plan to put a barrier in the chicane to stop folks from jumping them. Us master aged drivers will appreciate that!!!

Been chatting with Radford @ Wildhorse about some potential karting layouts that would be more conducive for shifters. In late September we look to have a test day where a handful of drivers will get to test a track layout similar to one of these. Keep it on your radar for the future.
