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

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.

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?

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.

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

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.

Following this thread.

Also from QLD, Australia.

Slight Update:

Those of you who follow us on facebook know we took delivery of our first Stage 2 car this week. In addition to being a stage 2 car its also getting a plethora of quality upgrades including the entire SPL catalog, DSS Axles, a stroker RJ MFG closed deck motor and a fully Built 7AT transmission as well.

We want to thank and welcome Nomodsjk for joining the RJ MFG Family!

In addition to that news we are also in talks with an alternative Intercooler company in efforts to reduce the complexity and overall costs of the kit. This is by no means a reduction in quality or performance. Depending on the news we receive this week we will have some more renders for you guys next week. We want to make sure the kit we deliver is 100%.

Our Goals are:
1.To deliver the best quality product on the market.
2.To beat the competition in $/whp
3.To deliver the most reliable kit

I can say this we will not be the cheapest kit on the market but when it comes to $/whp you wont be able to beat the value.

As of right now we will be doing a back to back comparison to the Stillen kit with a 10PSI upgrade (it made ~420whp and ~360ftlbs) on a 7AT. Our current Bench mark is set at 450whp with a stretch goal of 500whp.

Stay tuned for new updates and renders next week.

This makes me very very happy

So excited i cant sleep...haha...its like waiting for Christmas morning as a kid, zdays as a grown kid and your first awkward sexual experience all wrapped up into one octane fueled Z driven extravaganza! I can't wait to see what kind of numbers this thing makes but more than that i want to see that power band catapult me into the low 10's and maybe just maybe take the quarter mile blue ribbon!

This is going to be one sicko ride and journey. Stoked for ya! You chose a good username to follow suite. :happydance:

Cant wait to see how this turns out.

Somebody has some deep pockets! :yum:
Major monies spent in that project! :eek:

I don't want to know the final cost on this one

Haha me either...im trying not to think about it honestly. In this thread there's been mention of hp per $ but im thinking in terms of fun per $

Is there anyway I can do all that...without any money! LOL

You figure that one out and u let me know!

There was this...I wonder what happened to it.

http://i14.photobucket.com/albums/a3...a350Z/1608.jpg

That was a japanese company if I recall and a similar size to the old stillen kit which we all know didnt make much for power.

No. No it didnt. Thats why i force fed it with a turbo..lol. But ok, just never seen that picture before.

Not that I have deep pockets; but as this is my 4wheel (Harley-Davidson),,,when it's time to pull the trigger; Quality & Durability will take precedence over price...that being said, weather it be SC'd or TT'd .... decision will be made at that time.
I like this kit because of the use of pre-existed bolt on's....but it's gotta Perform!!!

I think the company name was ORC

Yes that was e85. The car picked up roughly 100rwhp switching to E85.

One thing to keep in mind about the "boost profile" of a supercharger, which I am sure you are well aware, is that its nothing like a turbo system. While the turbocharger is boost regulated, superchargers are speed controlled and speed is determined by the pulley ratio and engine RPM.

A *flawed* but easier way to look at it, is that superchargers operate at a set airflow vs RPM rather than "target boost". Again, as you already know, the boost generated between the supercharger and intake valves is merely a byproduct of the engines restriction. No matter what the engine thinks of it, that airflow is coming in. When the engine cannot digest it quickly enough, the airflow begins to back up and pressurize. When you reach the point where the increased pressure differential across the intake ports and cylinders becomes high enough to force the engine to digest the air as quickly as the supercharger feeds it into the manifold, this is your boost level. The boost level is how much pressure it took for the engine to reach an airflow equilibrium with the supercharger.

I know that nobody asked for an introduction to boost course, but I am just revisiting this stuff to setup for my point. Where I am going with this, is that the boost curve of a supercharger can be more difficult to predict, particularly on an engine with dynamic valve control systems, until you have a running example to extrapolate from.

There is plenty of room for the boost curve to end up being different on the VQ. It is difficult to know how much of the gradually increasing boost profile in my Coyote is a result of the blowers natural output profile versus a product of the variable valve control system dynamically changing the engines volumetric efficiency. Looking up dyno graphs displaying the boost curve from engines using the same blower, but without variable valve control, will give better insight to the natural output of the blower itself by removing a variable. The supercharger might actually be generating the airflow you desire at those low RPMs, it just might not be measurable as boost... which is often a largely superficial number.

I guess I could have just said that to begin with and spared everyone the essay.

Correct that is what I meant. For however accurate this estimate is, torque would follow it just the same since torque and horsepower are directly linked. Horsepower is a product of torque and RPM is its magnitude. A change in HP and Torque, at a specific RPM, will correlate as a percentage.

Rotating Horsepower Calculators - Horsepower, Torque, Speed

Check out this link for an easy place to determine what the torque would be at various HP vs RPM points.

Just so you guys don't forget about us here on the Left coast...
Any timeline on CARB?

As far as I know they are focused on getting the kit launched then following up with the CARB approval. I know this is one of their BIGGEST Priorities with the base level kit. There is a big market in Cali and I know they have their eyes on it.

+1!

Gentlemen,

We are still focused on CARB approval. Right now we are working on finalizing the design. We have made the switch to Bell Intercoolers for the air to water intercooler. We will be fitting a rather large intercooler in the kit capable of over 1000whp. The lower plenum is turning out to be a work of art with the integrated fuel rails and will be a very easy installation (Drop in and bolt down).

I seriously wish I could fast forward a couple months. I can't stop drooling over this..its worse than counting down the days until Christmas when i was 10yrs old

Quick update:

We are finalizing the lower plenum. We have made some design changes and will now be incorporating runners built into the lower plenum. We are also planning on running a 3" thick plenum. There are a lot of space constraints but the design is coming along nicely!

Any more CAD images for us to drool over?

We are working on them as we speak. We hope to have some renderings by this weekend. If we do I will post them up Saturday or Sunday.

As promised here is another lil teaser on the lower plenum. As you can see unlike other whipple kits on the market we are actually building in runners into the lower manifold adapter to improve efficiency and performance. Check it out:

Cant wait! This is getting exciting!

Also cant wait! Its killing me smalls!
