***Topgunz ROTREX C38R Supercharger Kit***

Duke370z

I have a FI oil cooler, installing it right now actually. Don't know how well it's going to fit with the sc kit yet. Just figured out I didn't receive any instructions with my kit and I think Aaron is on vacation. Making progress tho, dw fuel pump and cjm top hat are in, all wiring is done. Working on the cjm RFS still.

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.

Well I just ordered a Top Gun Speedworks Kit. ETA is 6-12 weeks out. I'll be running this on my '14 Nismo 6MT. Joining the Boosted Brotherhood of Z owners. CJM Fuel return and twin pump kit is also on order, ETA for them is September-ish. Will be switching from an Osiris tune to ECUTek tune in the process. Pistons and rods to be swapped too.

Will be running the ID1300 injectors. Planning to tune for E85. Track days are going to be more exciting I think. I'll post updates when stuff starts arriving and the install progresses.

Does anyone know if the Fast Intentions bar will fit this kit? I saw it did with the old A2A kit.

I got my car back a couple of weeks ago but I've been away on vacation, so haven't had time to post an update...

In summary, the car runs really great (and sounds amazing) but we had to limit ourselves to 480 whp due to me being on stock tyres. Even with just 480 whp the traction control light flashes now and then on full throttle even i fourth gear (dry surface; highway).

Once I find time (well, money) to upgrade wheels and rubber, we'll bump the power up. Possibly next summer.

However, I have one major issue. Start issues. The engine REALLY struggles to fire. Especially when cold.

My tuner (one local to me here in Sweden) is having a hard time improving it. I have a feeling it could be related to injectors/fueling, but I'm no expert whatsoever. The car had zero issues before the kit got installed alongside Injector Dynamics 1050cc and other supporting mods.

It really, really pains me to start it up. Here's a clip of it. Just before I shot this clip, I attempted another start which I cancelled after 8 seconds by pressing the start button again. It just wouldn't fire up. The second attempt is usually successful but only if I help a little by blipping the throttle. If I don't to this, it'll die right after it fires.



Any ideas? Is this a common issue with large injectors?

Did you upgrade your fuel pump?
