Topgunz full supercharger kits!!

turtle64b · 11-04-2019, 07:22 AM

I'm seeing 10.5 psi @ 5600 RPM now.

I was seeing about 5-6 psi with the small filter setup.

Still working out some kinks though (no pun intended haha).

The kit comes with the 9# pulley. It also will hit around 10.5lbs of boost after install.

There is a guy on here that did a study on the filter vs turbo guard vs turbo guard with pre-filter with just an Air to Air conversion kit and not my full kit so he has the low boost impeller.

Turbo Guard only - 9psi
Turbo Guard with pre filter - 6psi
K&N filter - 8psi

So he was only seeing a 1psi drop to filter air vs. ingest sand (silica) which will win over your aluminum block.

I am in the middle of developing a new intake among many other upgrades. Stay tuned folks!

Yay!!!! Good to see this kit still being refined and supported. And not deceiving customers and compromising engines by publishing dynos where no filter was used and not mentioning it. But instead, showing what even a pre-filter collects when using a turbo guard. Great work Topz.

For real, I work for a DOT, there's so much crap on the road surface, I can't believe people actually drive around without proper air filtration.

Can't wait to see the new intake design!

Not being comfortable running w/ just a stainless screen, I bought some unifilter 3/8" fine foam & fabricated a custom filter to fit over the stainless screen. It's a bit crude, but fits well. Glued together w/ RTV. I've not run it yet, so don't know what the flow will be. Maybe if the weather cooperates tomorrow I can test it out. It's small, but on the plus side, it's easy to remove to clean & re-oil. Again, not sure if I will stay w/ this approach long term, but I think it's an interesting experiment.

One issue I see with this is that if the foam gets old it could start breaking down and get sucked into the sc. You would have to monitor it to make sure it doesn't happen. It could be pretty restrictive also.

So I lost about 3 psi by adding the filter. W screen alone I get about 9.5 psi and about 6.5 w the filter installed over the screen.

Here is a pic of the pre-filter after just a couple of days. If you can see, there is sand stuck on the pre-filter.

I guess it depends on where you live. I ran a pre-filter on my turbo guard for a few days and saw nothing. But I live in the city. Also, pulled mafs and throttle bodies after about 1500 miles with turbo guard screen and they were spotless.

Aaron, I sent you a text last Saturday.

TopgunZ · 11-04-2019, 05:27 PM

But do you see the picture of that k&n filter posted above? All that would have gone into the engine. Not to mention everything that bounced off.

I fortunately don't have that problem in my area. Even when I took the stock k&n off when I switched to the turbo guard, the k&n was clean.

I'd love to see the dyno sheet comparisons of the k&n, turbo guard and turbo guard w/prefilter. When I had Seb do a comparison between the NGR screen and the turbo guard screen, it lost 1 psi and that just with a smaller screen size.

Senna-F1 · 11-08-2019, 11:38 PM

Something that small will be one of two things. Restrictive, or ineffective at filtering dust. No way around it.

Maybe it would be possible to remove enough black silicone from the top of the filter and shorten the silicone flange so there is just enough to attach it to the supercharger. This might provide enough room to shift the stock filter on and off the supercharger. That’s my plan as soon as I get my car back so that I can start working on my 3D printed plans for this.

Thanks for the confirmation. Wow, your car really makes a lot of boost w the stock pulleys and especially since u hv LTH which generally reduce boost due to their better flow characteristics.

Senna-F1 · 11-10-2019, 08:50 PM

Yeah, I don’t know why, and not convinced it’s all good. Tuner says might be due to his cam tuning. I would agree, but can’t tell and haven’t dynod yet.

Honestly I still have the same problem as you too. I can tell Sebastian almost seems a little frustrated, we've had to go down in timing from the base map to prevent ignition correction (usually it's the other way around, lol). He's brought up e85 a couple times now but unfortunately it's just not possible in my area, I would have to get barrels delivered, and I daily drive the car for the most part so it's just out of the question. The car goes on a dyno on Friday however I honestly don't expect it to make much power with the amount of timing it is running, I'd guess 450whp max. Sucks because this kit has so much potential just to be handicapped by bad availability of fuel.
