Topgunz ROTREX C38R Supercharger Kit

Birdiev · 09-09-2021, 11:17 PM

I hit 464 whp and 406 torque on pump at 9.5 psi
535 whp/463 torque on e60 and 9.5 psi
692 who/533 torque on e60 and 15 psi
Graph if off a bit because my intake pipe blew off and I was in a rush to pick up my son from school but will be going back in a couple of weeks as my tuner is going on vacation and I want to run on full e85. Slight misfire up too still had the oem spark plugs

Whooop! For the first guy to throw out some numbers, finally guys can see how efficient this Rotrex blower is. These are all SC records, especially with a filter on. Plus you havent even taken it to its potential. Full E85 will get you more power, it made peak power right before the coupler blew off, meaning there was some left on the table, and this was SAE!

What will a built block and 20psi look like?

Can you do me a favor and email me the graph in STD? topgunspeedworks@gmail.com

Nice build!

Awesome kit, how would you say the car feels compared to stock? Does it feel more torquey in the low to mid range RPMs?

Looking at the graphs, any insight as to why the blue and green torque curves start dropping after the HP cross while the red just keeps climbing?

Do you happen to have a plot for boost pressure?

The corresponding red torque curve would have also leveled then dropped off had the run continued. As you can imagine when viewing that graph: that particular run was stopped short at approximately 7K RPM where it the torque started to drop (the previous "blue" and "green" runs continued until ~7.4K RPM (looking at the graph, his intake popped off at ~6.7K RPM).

Well the red torque curve would had eventually dropped as stated by Northstyle. If you have more dyno questions let me know as I want to make a vid at the dyno and can asked the tuner some questions .If it's ok with Aaron I can post the link here to show the hp #s on the S/C as they are coming out.

Hell yeah man. Anyone buying a kit is free to post whatever they want. I've always been the kind of shop that isn't afraid to show whats actually happening. The more truth and data the better.

Wow it's absolutely impressive, awesome G37 right there.
It's a torque monster as well. It blows my mind thinking about all it's potential right here on this kit.

Woah….. has me reevaluating my turbo setup choice…… Any chance you got some vids you could post? You know we gotta hear that spooly boi noises and pshhhhhhhhhhhhhhhhhhhhh

Im working on it. There are some things in play that will highlight the kit with media. I am just waiting.

Think built motor, huge shop, professional photography. Should be ready in a couple of weeks.

I did get feedback that the Rotrex's spool sounds unbelievable. Just a lot of guys are still in the remote tuning process with even more guys in the install process and a lot of guys waiting for kits. I have shipped 8 kits this week alone.

@TopgunZ
Looking at those dyno graphs, running 9.5psi hitting peak 400wtq around 5500rpm but falling off to about 320wtq redline, for those of us on stock AT / stock block wanting to limit peak torque to under 400wtq but flatline / hold onto that torque till redline to still have a good 500+whp top end.

Can the mac solenoid / ecutek do boost by rpm?

Or are there / will there be different pulley options for limiting low/mid range boost but having some top end still?

Yes, we are doing this using the built in ecutek boost control.

So if using EcuTek boost control, does it help or unnecessarily complicate to have an independent boost controller in-cabin? Considering merits of Innovate SCG1 vs PSB1.

For $40 more the scg-1 let's you dial in boost per psi. But, it's not as fast going from say a daily map of 10psi to a kill map of 17psi. Plus, you will be tempted to dial it up "just a little more" lol

What would be your purpose for having an in-cabin boost controller if you already have the ability to change the map/boost pressure via the ECU?
