***Topgunz ROTREX C38R Supercharger Kit***

I use a 16-row cooler with 180F Thermostat, and 170F thermostat switch wired to 4 - IP68/75CFM fans - 670-OD8032-12HBIP68. Temps will slowly drop down below 200F while idling or stop go. Highest Temp I've seen is 218F while hooning.

I'm sure this setup is lacking for track use but works perfectly on the street, oil warms up very quickly and then stays around 190-200F, only creeps up on pulls but doesn't take too long to drop back down.

Getting close... really happy with the red, gives a bit of contrast. The FI oil cooler fit but a PITA to run and hook up the lines. Anyone else have to remove the driver side horn for the air filter to fit? Not a big deal just curious.

Yes. I think I had to bend the mounting bracket or something..

My car is not my daily and will never see the track, so this may be a pretty good set up for me or just go with a 24 row oil cooler. Thanks

Been a long time coming finding time to do some dyno pulls with Eugene. A couple weeks ago we scheduled a remote dyno tuning session at a local shop I have been using for last several years. The owner recently purchased a Dyno Com AWD dyno for the shop. The day I scheduled turned out to be about the worst weather day for dyno tuning, especially inside a metal building. The ambient air temps were over 100 degrees. IAT's were pretty dang high. We did put a swamp cooler type device in front of car and got the IAT's manageable. The owner of the shop had some learning curve issues getting the dyno setup and the graph to be what Eugene was needing. After several pulls it became apparent to Eugene that something was off with the graph. On the attached "IPS Dyno" you can see that it appears the end of the pull occurs around 7400 RPM and the power starts falling off significantly before 7K RPM. Eugene was watching the data live and said this didn't make sense with what the data showed. He recommended I find another dyno since he didn't trust the graph and didn't want to be adjusting blindly. Not sure what the issue was with the IPS dyno but apparently some setup issues exist in the software.

Yesterday I took the Z to another dyno near my house(Kwik Kar) and made some pulls just to see if the data from IPS Dyno could be duplicated and what the graph looked like. This is the same tune from the IPS graph just a little cooler weather, 96 versus 101. As you can see on the Kwik Kar graph attached, the pull extends to approximately 7800 RPM and the power doesn't fall off until 7500ish RPM. This graph makes sense with the logged data and Eugene and I will be scheduling another remote session using this dyno.

Both Dyno's are manufactured by DynoCom. IPS dyno is an above ground all wheel drive dyno with 2 rollers on front and rear wheels, it was operated in 2wd mode. The Kwik Kar dyno is an in ground single roller that the owner reported was calibrated by Dyno Com in the last 2 months. IPS dyno used STD correction and Kwik Kar corrected with SAE.

With all that said, the Log was showing 14 PSI for max boost and the car put down 534 RWHP and 450 Torque on an incomplete tune with E-80. I am looking to land at 600 RWHP and have a reliable street car.

Hoping to get the next dyno session scheduled and completed in the next few weeks.

RT Tuning just received my kit and my car will be going into the shop on Monday. Other upgrades will include 1300cc injectors and a Z1 24 row oil cooler. Power goals will be 625whp-650whp and keeping the torque on the lower side.

Nice! You're making the same numbers I was making on a fully tuned ACE Kit. Can't wait to see what you do with a fully tuned Rotrex Kit!
