I thought that car was literally going to blow my doors off.He made it to about the back of my door until he shifted and then I started to pull again. Then again rocket time for him but to my back bumper. Every time he shifted I would pull but that car sounded like a monster catching up.

Not sure if that was turbo lag or too big of a turbo ,and yes he got the hit on one because I wanted to make sure.

That's when I knew supercharger was the way to go because I was enhancing what I already had.

I've always thought the driver with the best start or launch will have the advantage.As it then becomes a catch up game depending on power levels. power curve has alot to do with it as well.

This supercharger is INSTANT power as soon as you get on the throttle. No regrets with this kit.

Sounds like if you come across him now he will look like he is standing still. He might have an eBay turbo and it's all show, no go. There's some companies selling kits now with $300 turbos on them. They might look "ok" on the dyno but real world is where it shows. Just like this kit on the dyno. Keep the hood closed and it will make the same power pull after pull. Close the hood on a turboguard and watch it ingest heat and numbers drop. Nobody does that though. And let me tell ya .. Those Facebook guys hate hearing the truth!

Looks like it. Hopefully the owner reports back with numbers.

Looks like he ended up making around 640whp and 440 torque. Not sure if it's the same one but ran into a kit tuned by admin on social media.

Has anyone done any comprehensive reviews/videos on the new Rotrex kit on its own and compared to other supercharger kits on the market for the 370z?

i don't think so but "thecarizon" on youtube has plans to upgrade his ace to rotrex last i checked. his videos are the most in depth (as far as DIY home garage style videos go) on the Z on youtube. So should be a good video series.

Just take a look at the dyno graphs vs the competition. These Rotrex kits are making way more power throughout the entire low and mid rpm range. Pretty easy comparison on what car will be faster.

Even at 10psi these Rotrex kits make more mid range power than other kits at 15psi and comparative peak numbers at the same psi. The Rotrex also obviously has much higher peak potential up to whatever power you're comfortable running.

That is true, I've noticed after comparing multiple dynos of different kits your new kit has a powerband that is strikingly similar to that of your typical VQ turbo setup with the exception that one is obviously lag free. I would just like to hear feedback on how the new vs. older setups feel in comparison. Would be interesting to see how this kit responds to pulley mods.

When looking at those turbo graphs do you notice how the tq drops off hard up top? I found it interesting to see how the Rotrex holds the TQ.

And in my previous post I was talking about Superchargers when I said "other kits". But comparing it to turbos is fun too.

Definitely, considering the turbos are appropriately sized the supercharger holds its ground better up top :driving:. Honestly that was the main selling point for me, prior to your kit I was leaning towards a turbo oriented setup but seeing how your kit was the best of both worlds it was clear to me which one was better :tup:.
