Topgunz full supercharger kits!!

Piping is aluminum. If going post blower it will pressurize it. Won't have that problem if going pre blower. Just not sure how you will be able to with the filter. Would need the stillen boot.

I don’t think they’d sell the boot but the design of it would sure help. Seb suggested around the filter so I was thinking of cutting some of the core support and using an aftermarket intake pipe that has a fitting for the PCV and then maybe I could fit a bigger filter

I have the Stillen boot if anyone wants to buy it.

So does this make more power, or just add unnecessary parts for aesthetics?

Not sure which parts you are referring to. I’m just interested in the air filter relocation. Here is a link to someone who did something similar with a 3-D printer but hacked away a lot more at the radiator support. The one above just uses the existing hole although it too may have been enlarged. Topz mentioned the 3D printed version would pick up some horsepower for sure. How much is not known, and probably becomes more useful as you approach the 550 to 600 power levels. SOHO seems to only publish dyno sheets of air to air supercharger kits that use a turbo guard. Why? There is some benefit but even they are saying they don’t know how much. Personally I find it strange, that a reputable shop would remove an air filter with no idea of the benefits of doing so.

Here are pictures of the turbo guard and ngr screens that I supplied Specialty Z for dyno testing. You can see the results on the second page. It was a drastic drop just with screen size.

Sorry Senna, haven't been on for a few days. Anyway, I was referring to whether or not the VHR manifold and added piping made a noticeable increase in power over the Stillen manifold, or if it was just for looks.

In regards to bullitts numbers, I'm wondering if it was actually the manifold or relocated filter that made the difference in power. I remember when redondoaveb (sp? sorry bro lol) posted dynos with the sandwich filter and with the turboguard and he made similar jumps in power so who knows what the actual difference maker is, the filter or the manifold?

Senna-F1

WHAT? OK, these numbers are mathematically impossible. Just look at the 0 TQ increase that resulted in a 15 HP increase. Anyone that knows anything about TQ and HP knows that's not how things work. A 0 increase in TQ = a 0 increase in HP. So, let's look at these other suspect numbers. Here is a chart of what the supposed increase in TQ would give you in extra HP.

I remember a few years ago reading through hundreds of posts when this conversion kit came out waiting for the page that would show the dyno chart. I wasted 1-2 days reading posts and never saw a chart. And again, no chart with some wildly inaccurate claims about this conversion.

Your graphs are not overlaid correctly. TQ and HP should always cross at 5252 RPM. Maybe you should line them up better.

And yes, your posted numbers that we were expected to accept at face value before I called you on it are absoloutely BS. Mathematically proven BS.

Again a customer sent me this. I will get his original graphs and compare side by side

For those asking I was asked not to share the dyno due to the belt slip at upper rpms on the non-gtr plenum car... both cars have an identical build minus the gtr plenum. GTR > Stock VHR > Stillen plenum

Also I am not RJM... this didn’t come from RJM... this came from a customer. My comments are based on the overlay you see above.

just got both graphs… let me do a comparison.

GTR Plenum Vs OEM Plenum:

3.5k: +10whp (190 OEM vs 200 GTR), +10ftlbs (290 OEM vs 300 GTR)
4k: +10whp (230 OEM vs. 240 GTR), +5ftlbs (310 OEM vs 315 GTR)
4.5k: +5whp (275 OEM vs 280 GTR), +10ftlbs (325 OEM vs 335 GTR)
5k: +10whp (335 OEM vs 345 GTR), +5ftlbs (355 OEM vs 360 GTR)
5.5k: +10whp (375 OEM vs 385 GTR), +10ftlbs (370 OEM vs 380 GTR)
6k: +5whp (420 OEM vs 425 GTR), +0ftlbs (370 OEM vs 370 GTR)
6.5k: +0whp (460 OEM vs 460 GTR), +0ftlbs (360 OEM vs 360 GTR)
7k:+10whp (490 OEM vs 500 GTR), +0ftlbs (360 OEM vs 360 GTR)
7.5k: OEM Slipped...

My Apologies for the misrepresented information. I was able to get the individual dynos and run through their respective numbers. OEM Max was: 492whp/378tq the GTR plenum 515whp/377tq.

I will clean up my posts prior and we can use this as a reference for the gtr plenum. Both cars were on pump gas and at 10PSI.

How are you coming up with these numbers? I mean just looking at the 7000 RPM Number, 360 TQ @ 7000 = 480 HP, not 490, and definitely not the 500 you are showing. And if the graph you are using clearly showed the 2 curves were shifted incorrectly horizontally, how do we know they weren't also shifted vertically? That'd be a really easy way to show an increase in power! Sorry but your numbers and methods are suspect. Different car, different day, different dyno? Im not sure. And then instead of using actual data, you overlaying photos to compare. It's just not working.
