Ohhh and for our Australian brethren I believe they are already in talks with an Australian distributor. I can't say the name of the company since nothing has been finalized but I suspect the RJ mfg prices are about to get a lot cheaper for you guys!

If this is true, I am 100% waiting for this kit, no doubt about that!!!

Good call waiting on this rather than the Gamma kit!

Could you elaborate or explain to us laymen what you mean mean by "crank pulley" ?

This isn't going to fall in line with the serpentine system?
I have no intention of getting rid of my ATI damper

I wouldn't expect any stages and pricing for several weeks. RJ MFG is working with laminova directly about the intercooler core. the design there isn't finalized and that will affect some of the other parts. I can say they are looking into mezeire (sp?) 55gpm pump that has a 3000+ hour pump life! That's a huge leap up from the bosch pumps stillen uses. Also after reviewing the cooling capacity I believe they have decided to stay twin pass on the heat exchanger.

The current idea is to run a 4" crank pulley and a blower pulley ranging from 4"-2.5" for stage one. Now the stage 2 guys I think they are bumping the crank pulley up to a 5"-6" crank pulley. So far I believe they are trying to limit the drive ratio to 2.0. At least for those looking to rev to 8.5k-9k. If you stick to lower revs you can get more of a drive ratio (2.4 if your stock rev limit).

It's definitely going to be interesting to see what they come up with. But if I had to guess I would guess that the price per hp will be competitive. The stillen kit is about $19/whp averaging 420whp on 8psi. The GTM/gamma kit is more expensive at $22/whp averaging 410whp on 8psi. This is based on their retail pricing. So if RJ MFG are able to make 450-500whp on 8psi they would be competitive pricing wise with what they have stated thus far.

I am stoked!


500 wheel @8psi would be mega - Dont think thats out of the question with a 2.9L unit, hopefully torque will also be close to 500ft/lbs.

Stage 2's 600whp @12-13psi anyone?

oh wow that would make life easier - they would probably know how to deal with all the legal issues as well especially regarding the bonnet. (Hope its Harrop or someone at least well known to the local community)

For all you other Aussies did a bit of digging around CF hoods and FRP hoods are illegal due to some sh!te about they don't crumple in an accident and can shear off in sharp pieces, also hood vents need to be meshed so a kid cant put their hand down a vent and get it caught on pulleys etc.

On the bright side there is 1 company in Straya that does aftermarket hoods and bodykits in FRP that are ADR legal. Apparently they even provide the paperwork to show the cops and they have just started transport approval to work with carbon fibre and all their kits are street legal in all states and territories NFI how they pulled that one off.

They've also been working on cars with PD SC kits so as to allow for more height and space for air around the SC and CF functional vents directly above it - looks alright

BLITS BODYKITS NEWS PAGE

But in terms of styling the world's our oyster fellas if this bloke can churn out items that are fully street / ADR legal then someone needs to check the so called paperwork, but on other forums everyone says their legit:happydance:

If that really is the case lets go to town and rice the poo outta it fellas, Varis Kamikazi R style hood or Top Secret style hood with a v8 m3 style powerdome...hmmm

I think most are looking for flat or at least linear, increasing, torque. To make 500 hp and 500 hp, you will have peak torque before 5252 rpm with a sharp drop in torque after that. You only need 350 ft/lbs at 7500 rpm to make 500 hp.

nice correlation of torque and horsepower.. rare to see an understanding of that. while this blower makes instant boost, it doesnt make instant full boost.. at least it doesnt tend to in the applications i am used to watching it work. on my coyote the boost somewhat ramps in, so the peak torque can occur some higher and stay flatter.

but i still dont think we will see this blower make both 500 HP and 500 torque from the same pulley, probably going to have to pick one or the other. 500 torque is too much for the stock engine for 90% of users IMHO anyway... reserve that much for the risk takers.

heres the whipple 2.9 in action on my coyote, which as a 11:1 v8 DOHC. not all that mechanically dissimilar to a VQ + 2 cylinders. Notice the boost curve. I bet if you take the numbers and multiply x 0.75, that is probably rather close to what you could expect to see in VQ performance with it.

jchammond 01-14-2017 08:01 PM

nice line's on the graph mr.phunk!
As to produce that kinda torque low and @7500rpm shift's w/the A7,,,mine only falls back to 5500 between shift's. That would be sweet; as we all would need 325's or 345's out back!

Nice numbers Charles must be a hoot was that on e85? interesting to see how the boost comes in 7psi@2400 - 10psi@4200 - 12psi@5800 - 13.8@7500

Not what i was expecting thought it would be fully lit from down low.

So going by 0.75 multiplication that would work out to roughly 611whp @13.8psi is that what you meant?

And would torque roughly follow this rule?

If not what would you assume torque would be @500 and 600 wheel respectively?

jchammond 01-15-2017 06:42 AM

I'm not running any corn yet; still e-free93,,,so 525/425 H/T would suit me for now (stock bottom end).
I just like that steady hp climb & how the tq stays flat across on the Coyote...to fall back in peak tq after a shift would be awesome!

Gentlemen we will have more details on what to expect for power levels once we start testing. We get our first stage 2 car on Monday. We have our in house car already being prepped for the stage 1 kit. Once the kit is finished in the design process we will begin testing. As for the lad who was wondering about the ATI dampener I haven't forgotten about you. Your dilemma was something we had already talked about for the stage 2 kits. Since a built motor would be needed for those kits we were looking to include one in the upgrade along with an ATI specific Crank Pulley. We can definitely make it an option for those wanting to go stage 1.

Also, before we go throwing number around we will be performing a drive ratio test of 1.0 (4" crank pulley and 4" blower pulley) to confirm our calculations on psi levels to pulley sizes. Once that is done we will let you know what to expect from real world results.

Expect thorough documentation and testing in the coming month or two.

JJ's370z 01-15-2017 10:24 AM

Cant wait for the results, man I'm so impatient really interested to see what this will put out #'s wise with a Stg 2 & built motor.

Def convinced i'll be going this route and this is the best FI method for VQ's - turbo torque but a much more linear instant delivery - Well done RJM for the insight and not swaying to the crowd at the time who wanted the Rotrex (inc me).

Seems a good "lil" unit. Whipple W175ax on a 48hr durability test:

Can someone tell me is that black rod a carbon driveshaft to spin the front of the rotors?


And since were modifying the bonnet it would be remiss to not include this as an option

ACGz34 01-15-2017 11:10 AM

Sub'd can't boost till I'm back in the states till the end of July. If this becomes a thing I will definitely go this route if numbers are right for the price.
