TopGun Rotrex 370Z Nismo -

The track was hot and the tires were greasy, but I managed to grind out a 1:13.378. This is with full interior, full weight, 220 treadwear tires, and powered by a Topgun Speedwork Rotrex kit on a stock motor.

Putting in work!!!

Good lap. What microphone are you using, and is it placed inside or outside of the car?

[@jonathanwheeler7301]

It is built into the catalyst. I recently covered them with sound dampening foam thinking that it would help and you see the results. I’m going to step up my efforts and find something else more powerful at muffling the air turbulence within the car

Nice 👌 How is temperature situation after installing supercharger? How long can you go before it overheats?

[@jonathanwheeler7301]

Placement of coolers and ducting is key to keeping a Z cool on track, regardless of supercharger. As for time on track, that just depends on how hard I’m driving and on what tires. A street tire can not take 20 minutes of proper abuse and the tires normally give up before the temp gauge.

@@jonathanwheeler7301 I agree, ducting is super important, but still even with ducting I have troubles keeping my N/A cooled for 20 min. What tires are you using? Are street tires required to race in your league?

In the beginning of the video were you lifting down the straight?

[@jonathanwheeler7301]

Yeah. I wasn’t sure I was going to get another clean lap and was debating running a cool-down if Jake had lifted in front of me. When I saw he was staying at pace, I got back in it.
There was a lot of time left on the table…

@Jonathan Wheeler that makes a lot of sense. The car rips regardless! Sucks that a traffic situation kept you from going even faster
