Topgunz ROTREX C38R Supercharger Kit

edub370 · 05-26-2021, 07:30 AM

So before these go on sale will there be any results that don't end in a failed motor? (That sounded way snottier than intended). But I'd like to see some 93 results on a stock motor.

I'm really interested in this kit, but lack of longevity on any cars is making me a touch nervous

I'm kinda nervous as well. But I would be nervous (in the beginning at least) with ANY FI setup.

It's a lot of money and if something goes wrong, even more money. Big money.

However, I've been wanting a solid supercharger setup for many, many months now, and for me, this is the one. Even if it means I'm amongst the very, very first to try it.

My engine failed on me last year (rod knock) so I had it rebuilt completely (using upgraded parts here and there). Lots of money there already. Fingers crossed I don't run into more trouble down the road. Aiming for a somewhat conservative tune, I suppose you could say. Around 525 whp (600ish at the crank). Plan on keeping the car for many, many years to come (third car, not a daily driver, summer only).

And this is the other approach we decided to not try. At 525whp then you do not require a built block since there are years of data to support that. The car owner now wants 800whp, which will obviously require a built block.

Yeah, I didn't have my engine rebuilt with upgraded parts in the name of my initial 525whp goal, but a few years down the road, I might see myself with a desire to move towards 700whp - depending on how it behaves on the road with 525. Plus, I've never owned a car with more than 350whp. I'll prob get myself in trouble jumping instantly to twice that power.

My car will only be for normal road use and will never see the strip or track, so if it turns out it struggles with grip at 525 on the road, I'll probably just leave it at that power level. I don't want to be spinning the wheels all day long in 3rd gear and up.

700whp is not a problem with the correct mods and tire. 1st and 2nd are the only useless gears. Go above 700whp and that is where it starts getting interesting. You have to learn to drive with your right foot. Starting off at a lower level is the right approach to not get in over your head. What's nothing to me may scare the crap out of someone else.

Yeah, I wish that the focus was on a general, turn-key install.

"Here is what the average Z-owner can expect if going for a simple purchase and install."

TopgunZ · 05-26-2021, 11:14 AM

We have results. 708whp/556wtq and then ran out of fuel. All of this is in the thread.
We then went back with larger injectors to see the full potential and noticed the coolant spraying out of the overflow, then pulled her off.

We did not have a failed motor, we seen signs of head lift due to pushing the limit and trying to find the top end potential of the kit. That was our goal. Which turns out is enough to lift heads. If you dont want to lift heads then do not set the boost so high through ecutek and make boost/power levels that will not result in head lift.

The kit can be set to whatever power level you want so it has ZERO bearing on the kit blowing the motor. What does have a bearing is the PSI you feel comfortable making.

This is just like any turbo kit. Most kits have the potential to create dangerously high power that can take a motor out if you try. This just so happens to be the ONLY supercharger kit that can recreate that since it makes incredible power. Just dont full send it. We only did to see the upper potential.

Plus there are a few dozen kits that will be on the road soon.

Not just a few, but a few dozen, you say?

I look forward to the reviews. Keep it up.

I'll make sure to post a review once mine is done. My install will probably be delayed compared to others, though, as I need my kit shipped to Europe. Not sure how long that takes. 2 weeks of total shipping time would be my guess.

TopgunZ · 06-30-2021, 06:06 PM

It's a fair question. All that needs to be said is that they are so similar it is comparing apples to apples.

SpoolyD@SZR · 07-02-2021, 04:50 PM

Got a customer that's excited to get his soon. Looking forward to tuning it on the dyno.

Birdiev · 07-08-2021, 10:03 PM

I'm excited as well. Please let us know when they get shipped out. Will be sitting outside waiting for the kit to arrive.

TopgunZ · 07-12-2021, 07:31 AM

Multiple kits will be shipping this week. I will be shipping as "Hold at Fedex location" closest to the provided address. This protects both parties from porch pirates and over handling. I have seen how FedEx and UPS deliver heavy boxes. They usually slam them down on the cement approach and then if nobody is home they slam them back into the truck and repeat the cycle.

You should see how they throw them on the truck!
