Well, here is a screenshot of a video from the dyno today. It's the best I got. Lol. We are taking professional photos once it's tuned.

The filter is placed where you can remove it for cleaning by simply pulling back the fender liner.

You could also swap on a turboguard easily but I don't think anyone will want to unless they have a fully built motor.

Is this going to have the turn key option like the ace did? Injectors, fuel pump, tune...etc etc.

Also, if someone (me af) didn't want to go into the built motor arena and really just wanted 400whp daily (or rigorous track abuse) and < 550whp when doing power pulls (just to stay safe and be happy with the car for a longer time).....How would they go about that? Just control the boost with the interior mod you talked about?

Everything you need for a complete kit is on my site. I'll place what to buy for what power levels in the description of the supercharger.

Yes, there will be a way to control boost. Trust me it's going to have to happen or I am going to start selling my own line of pistons and rods.

See that's the thing I admire most about the work you do. You think ahead of not just that the product be good, but what the not so logically enhanced people may do with that great product and then blame you for it...lmao. As sad as it is, it's the reality. You minimize all obstacles that someone can run into due to negligence or ignorance, which is why your stuff lasts. I've seen many great products and ideas (not just with cars) go to sh*t because of how they were used or what people did with it...good stuff brotha

What’s the maintenance like on the c38R? Is it gonna need a dedicated oil cooler?

It comes with its own dedicated setrab oil cooler and reservoir. It doesn't require a pump so there isn't any wiring involved. What does this do? Aids in longevity and 50,000 mile oil changes!

When you say zero BOV flutter, are you combining the noise that also includes the compressor surge/chatter? If so, is this solved by the intake tubing and the pleated filter? Is the positioning of the Vortech s/c on the ACE system compatible with the new intake?

Thanks.

Always disliked the design with the Stillen plenum so I went with the BP kit. Found out that PTE turbos no matter how you tuned them had too much of a spike on track so I was gonna switch to a Garrett G series hoping for some improvement but this might be the way to go!

This thing moves power way left on the graph. But it is also perfectly linear so it is extremely predictable. Just bleed off whatever boost you don't want at the top end. It really makes for a great track car. We will have a few heavy track use builds this year.

Flutter=chatter. Its not surge on the ace kits it's 100% the bov oscillating. I've said this a bunch of times. It's just audible from the supercharger inlet. I have my custom bov filter on the QRJ plus a filter on the supercharger so it eliminates the audible fluctuations of the bov under a zero vacuum situation.

The intake and filter cannot work on the vortech units. They get positioned too far up and over to get a pipe to them.

I'm sorry, I must have missed you explaining it this way. The installer explained the noise differently to me. Is your custom BOV filter similar to the Vibrant crankcase filter? Would that addition (along with the QRJ) to the system be enough to eliminate the flutter, or is the intake tube and pleated filter contributing to the noise suppression? Are you mounting the BOV filter in a remote location? Are the mounting brackets and the intercooler identical to the ones supplied with the ACE kit (therefore the space between the intercooler and the radiator the same)?

Gonna have room for 3 coolers for a 7AT? I see it’s up for preorder on the site now...

Depends how big the coolers are. Any pics? And why 3? 2 oil and 1 trans?

No pics yet, but would be 19 Row for Engine, 19 or 30 Row for AT (I assume I’d need this if installing SC) and whatever size for the ACE. That said, I’m sure a custom bracket wouldn’t be a big deal if I’d be going SC’d. I’ve come to grips that I wouldn’t need my Dewla Air Guide anymore :)

TopgunZ 04-05-2021 08:56 PM

Ran out of time on dyno. We were just making some power.
19psi at 7400rpm with a full filter setup at 1000ft elevation.

Without a filter at sea level revving to 7800, I bet we see 23psi.

Back to the dyno Wednesday.

It's a good thing you're installing a boost controller :rofl2:

TopgunZ 04-07-2021 07:44 PM

Topgun Speedworks ROTREX kit release!!! With a FULL FILTER!!

708whp!
556wtq!
21.5psi!

All at only 7000rpm rev limit!

Stock block!

We ran out of injector. We were at 107% injector duty cycle at 7000rpm. Conservative tune.

This kit will hit 23+psi and make 750whp pretty easily with more fuel. With a full filter! We need a built motor to see what happens with a turboguard.

This kit will be able to bleed off boost for whatever power you want to make.

Still the most affordable supercharger kit on the market!

Tuned by the best... Eugene Turkov

Great numbers, especially with a filter. Are you going to do a 17 psi dyno run?

Birdiev 04-08-2021 04:53 AM

How do I order this on website? All I see is the ace kit.

Damn... looks at that torque line, so much low to mid range power! Lots of fun factor right there without having to go TT's.

Jayhovah 04-08-2021 09:16 AM

Smells like alotta folks are about to go boosted.

Yeeees sir. I’m contemplating this or an FI TT setup only because the wife drives the car and she has never driven a single turbo car, only TT and SC. The more linear power curve will make it a lot easier for her to adapt. Decisions decisions....

Need video clips of this kit! Siiiick.

TopgunZ 04-08-2021 10:08 AM

The best part....we are barely scratching the surface of this kits capability.

I have a video clip on FB.

JARblue 04-08-2021 10:31 AM

Got any videos to share with people who aren't on FB or IG?

cgr406 04-08-2021 11:08 AM

This is awesome! So what's the upgrade path / cost for those of us w/ the ACE kit? Or haven't you gotten there yet?

There will be a buy back program. I have not worked out the numbers.

NorthStyle 04-08-2021 06:33 PM

Amazing results!!

2 questions:
1) Is there any particular reason you only ran up to 7k rpm on the dyno?
2) Is the boost control function included in the price of the kit currently listed on your website?

EDIT: Ran out of injector... nevermind lol :o

TopgunZ 04-08-2021 07:07 PM

1) Seen you got it
2) yes!

redondoaveb 04-08-2021 07:11 PM

Is it going back on the dyno with the boost controller? If so, can you give 17 psi results.

Geeoo 04-08-2021 09:36 PM

How much boost/power can we safely run on the stock motor with this kit?

My guess is many factors contribute to it. I always was under the impression 12-14psi was max. But, that was because some guys were going SI trim on the Vortech, upgrading the turbine, upgraded bearings to overspin. That was bringing on the torque hard early in the power band. Torque is the breaking factor for rods/spun bearings.

I don't think i actually ever heard of anyone actually going through a headgasket with the v1/v2 kits even at 16psi.

So, how much boost can we safely go before headgasket problems.

NissanTracker 04-08-2021 10:03 PM

I also want to know... how much of the Knock sensitivity is being turned down for these numbers 16-20psi?

We will be going back to the dyno with 1450cc injectors and boost control in place. We have the Innovate SCG-1 so we can dial it right in.

Yes torque is more of a factor on motor longevity. However, it also hugely depends on how that torque is delivered. Do you see how perfectly linearly the torque gets ramped in on these kits? That is friendly to the motor as it does not experience an impact of it. Also the higher in the rpm band you can push the torque the easier peak torque is on the engine.

Turbos take all that torque and slam it in very early in the rpm band which is that "rush" feeling...and then they taper off. This is also a fun experience as it hits like a freight train, but is harder on rods. Go look at a dyno graph of a single or twin turbos and see how the torque looks.

This kit brings torque in and it just keeps climbing which is a totally different experience than turbo setups. The car just keeps pulling and pulling like its trying to exit the damn atmosphere! Much more predictable. Especially for a track setup.

I have no idea as I didnt tune it. But knowing Eugene and the fact, that to my knowledge, he has never blown a motor...Id say he left them untouched. I know 100% for sure he keeps on all safety features. Some tuners out there turn these off completely to make "numbers".

Honestly, there is still a ton of power to be made with this kit. But the car owner doesnt really want to see what its full potential is right now since its the beginning of car season.

However, DYNOSTY is getting one of the first kits and is going to full send it!!

I speak conservatively when I say 800whp will be broken.

NorthStyle 04-09-2021 07:45 AM

IIRC you mentioned previously that these numbers were on E85, when should we expect to see the 93 numbers? I'd love to go E85, but it's just not readily available in my area (without a 45min one-way trip)

Another Q: what was the fuel system/components for this vehicle?

Holy mother of god.... Need to stay tuned for this.

NissanTracker 04-09-2021 08:11 AM

That torque line is pretty insane. Decisions, decisions, decisions. I'm working on a built bottom end this year in my spare time, so when that is done... I start deciding which FI solution I'll go with.
