RJ MFG Supercharger kit Feeler...

Whipple is the way to go!!!!

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.

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.

this is just too much. 500whp is going to require $k's in support mods, including at least $1200 in ecu and fuel tuning stuff especially if you are going to pass carb which with 500whp you won't you just can't make that power cleanly on this size motor, hell it barely passes smog as it is and you certainly arent getting to 500whp with factory cats. 400+whp and a kit that costs 7k are doable but you are still going to need a clutch unless you want to get your car painted in authentic jesus blood, sancitfied by at least an arch bishop, and pray that your stock clutch, stock fuel pump, stock cats, and stock ecu are going to hold up to double the manufactures rated horsepower. next tell him you want a 30,000mile b2b warranty while you're at it.

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!

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

JJ's370z · 12-05-2016, 03:29 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.

shadow85 · 12-05-2016, 04:56 AM

Yeah like Jj asked, what sort of time frame will we be looking at until it is released for purachse and will it be made to fit RHD aswell?

Me and a friend of mine were actually on the market for a SC kit and were very close to pulling the trigger on a Gamma Stage 2 kit in the coming weeks, and now I see this thread!?

Very interested in this one but don't really want to hold out forever when I can get the Gamma stage 2 rite now.

Thanks.

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.

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

bullitt5897 · 12-05-2016, 08:01 AM

Hey guys I spoke with the owner of RJ MFG over the weekend. They have already posted up some pictures of a kenne bell 2.3L twin screw they had in stock on a VQ. As of right now I think the direction is headed into the realm of the positive displacement superchargers. They are looking into superchargers in the capacity of 2.3-2.9L. They are also focusing heavily on cooling for Both the motor and the supercharger. With these sizes we will see power levels well into the 600+ rwhp range. From my conversations and their initial measurements the fitment of this inside the hood might be doable but they are still doing measurements to ensure proper fitment. It's definitely exciting that's for sure!

TopgunZ · 12-05-2016, 08:43 AM

Where are these pictures they posted up?

Zat_Zuma · 12-05-2016, 11:35 AM

They posted the pictures on facebook.

I like the simplistic approach to top mounted superchargers like Kenne Bell but their is major heat issues to deal with. They are popular with the Hemi engines for a quick, but expensive, additional horsepower solution. What the advertising doesn't tell you is that detonation from the heat is paramount and damaging. The tuning is set back so much that the horsepower gains are low for the money and the risks are high. Unless the engine is forged and heat issues are controlled, it may be a disappointment and some major damage. I don't think the VQ family of engines are up to the task.
This is why I favor air to air intercoolers when boosting VQ's to help control some of the heat issues.

bcfromfl · 12-05-2016, 11:48 AM

I'm in favor of a well-designed unit that doesn't change the look of the stock engine compartment so much like the Stillen does. Plus...there must be some losses by y-ing together the intake? Prefer how GTM designed their kit.

Also, I know there are guys who love the whine of superchargers and the BOVs, but I'm in the camp for quiet operation. At least offer an option for owners who don't want to announce their car to others from a mile away?
