Topgunz ROTREX C38R Supercharger Kit

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.

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.

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.

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.

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.

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.

Also what are we looking at in terms of boost figures, and will there be an option for conversion from your old kit?

I second this, as a resident of the "great" state of california

What are the advantages of going with Rotrex over a Procharger unit?

All of that information is on the first 2 posts of the thread.

vortech = procharger. They are similar systems. Some simple research would have told you that.

cgr406 · 06-30-2021, 08:05 AM

Hi Aaron, any word on pricing & availability of kits to convert Ace setups to this one?

Isn't a part of research asking questions? Why not get it from the experts ? Oh alright then

Yes, but when you ask questions that can be answered via Google search and then the first post of the thread, you identify yourself as a lazy person. If you had said, 'I read xxxxx and xxxxx, and I don't understand 'yyyyy' and 'zzzzz', you might get a different response. It's like asking 'what kind of oil should I use in my car', when there are easily half a dozen threads on this forum about that topic.

That's okay, continue to be lazy. We like lazy people here.
