RJ MFG Supercharger kit Feeler...

Option 2 as I'm only looking for something in the 500 whp range, but I got not problem cutting my hood for a sweet blower at an affordable price.

looks like Roots Supercharger is making a come back.

I'm not against the twin screw option and its benefits, but cutting into the hood for clearance cuts out a lot of potential customers. So now you have to buy a new hood or be a redneck and run around with a hole in your hood to fit your supercharger.

I liked the stillen hood for the the 350z when i had their top mount sc. I even left the hood on after I took the sc off and went turbo. Got lots of compliments on it too and stood out from the rest of the Z's, Both visually and audibly. Oh how I miss that sweet sweet formula 1 whine!

New hood or hole in hood are not the best options.

if you go roots go big and make it a power tumor/70's challenger Shaker hood air inlet blower cover thing. <--I was once a "redneck" duct tape and all.

HAHAHA 'MERICA!

We are taking one of our mustang Kenne Bell 2.3L and seeing what it will take and what design options we have given our space constraints. I hope you guys are excited cause we sure are!

OMG, i'm a T/A guy, if i could get a functional shaker hood for a Z with roots blower under it, i'd be all over that

RJ MFG · 12-01-2016, 02:25 PM

Given the interest we may do both. The twin screw and the rotrex have their advantages.

avery370z · 12-01-2016, 03:22 PM

Whipple is the way to go!!!!

batboyvaj · 12-01-2016, 03:46 PM

I believe that the GTM/Gamma Stage 2 came with a c38-91 Rotrex. Whatever you decide to build, make sure it works with the CSC delete kits.

Zauskycop · 12-01-2016, 06:08 PM

I want reliability. I don't want to cut my hood... A2A is a definite. I want reliability. I am seriously in the market for a SC, and plan on running one in the 2017 One Lap of America. 3500 miles, track days, long commutes, and long days is the norm. I NEED RELIABILITY.

I am sick of losing to 600 HP Supercharged Mustangs. I can beat them on handling tracks, and make it a close race on longer tracks, so I don't need 600 HP, but if I can get 400-450 WHP and RELIABLE, Im in.

Jinxx · 12-03-2016, 03:52 PM

The gamma stage 2 will put over 500 whp with stock clutch and cats/exhaust and its selling for 8800 easy install and very reliable

Yep, i have one for daily driver, love it, except for summer when heat soak is an issue, but i'll be getting a fuel return kit put on. As it has been said already location of intake is next to the headers wtf.

JJ's370z · 12-05-2016, 02:29 AM

Will this kit be RHD compatible?

Once you decide what platform your using - when would be a realistic time frame from R&D, development etc to ready for sale? Just want to factor in how long i might be waiting for this kit.

I voted Rotrex c38-92 but thinking about a whipple and the beefier low to mid range for daily driving sounds really tempting, but I would prefer the pull of the c38 at a track day and when I'm getting on it...hmmm decisions.

Out of curiosity are you referring to Pro Chargers i-1 Programmable SC or an earlier model?

On 2nd thought the Lotus exiges come stock with a twin screw on the 2zz and although ppl do upgrade to the larger eaton style units when you want to make big power the fastest cars tend to use the Rotrex units.
Here's a c38/90 making 604bhp to the wheels on a stroked 2.2l k20a type R motor @20psi
https://www.youtube.com/watch?v=58g0ubJzs5w

They usually track it around 520whp
https://www.youtube.com/watch?v=31yZHSYwF3g

So if they can make 604whp on a 2.2l with a c38/90, surely 600whp on a vq37vhr with the larger c38-91 should be viable.

And are we talking 600whp on pump or e85?

Yeah Rotrex for me at this stage.
