I can 3D model this for you. I also have a $60K 3D printer for items that don't need much force since it uses ABS.

Funny this is being spoke about now. Just last week I was looking at my extra parts from my old motor wondering how I could get a roots on there. Needless to say, I am extremely curious about this project.

I think the biggest challenge will be to fit it all under the oem hood. It will need something like the TVS2300 to get the power we are all looking for.

Roots setups are just so simple and effective. I would rather put one on then take my cats off again..lol.

I would love to see a roots blower, but the hood fitment is going to stop many from jumping on if it requires a new or modifying a stock hood.

i would love to see a roots blower aswell, but im talking with martin on the gtm kit now. the only other thing that i could see being a problem is the motor mount. i talked to shasha before about just buying the charge piping from his kit to do a custom turbo, so with those brackets and his charge piping you just need to buy the rotrex and you got a tuner kit.

on another note tho, if i were to get this kit off of martin i would have the blower to play with, if i were to make a bracket out of wood i could have it reproduced out of aluminum anitvenom, and topgunz i could have you print out a custom intake portion to the blower?

the progress of this thread continues to make me smile. :tup:

I have an extra set of bp intake piping if you need it.

I could totally print an intake for the filter too.

A decent positive displacement blower itself will fit under the hood... I think where you will run into problems is when you remember the intake manifold, intercooler, and pulley.

The timing chain covers and 60 degree block wont fit the blower at the bottom with the manifold on top like the hellcats or ZR1, so you have to put the blower on the top like the typical mustang setups. By the time the SC pulley clears the timing cover its probably already through the hood, and you probably still dont have enough space for a plenum and intercooler underneath it.

Hopefully next week my 2.9L whipple for my mustang will be here. I will take a look and see if it is even REMOTELY a possibility or just completely no-way. I think I know the answer but I will have the required stuff sitting around to look-see.

I think you would have to run the drive unit out the back and down the side of the unit similar to stillen's Titan unit:

Then you build a bracket and tie it into the pulley system. I think the biggest hurdle would be the Fuel rails and lower intake manifold... next would be to ensure you can get the strut bar back on the car...

The unit would most likely be a whipple unit anyway...

My whipple thats coming has that built in

I think it will be a big mess for the VHR... especially with the dual throttle and all. I just dont see how the air piping can fit over the timing covers anywhere.. So the inlet would probably have to be in the rear, I am not sure if we can do a rear inlet that goes both directions while still having a rear drive for the blower. But I will peak around the different configurations they offer and see if I notice anything.

You could cast an Inlet head to house two throttle bodies and run piping to one side. This would mitigate both of those issues. The dual throttle bodies definitely pose an issue and regardless both pipes will have to go in one direction similar to the current stillen supercharger kit.

I think no matter how you slice it, the pulley or jackshaft will be in the way on one side for the throttle

Charles, just duplicate gtm's kit and sell it to us! I'm sure alot of people are interested. :)

I would never duplicate someone elses work... but that doesnt mean I couldnt make something better that is partly inspired by it.

Problem is, I am in the middle of an intake manifold, turbo manifolds, crazy FMIC setup, and an updated road race pump. Maybe this summer I could look into putting together a SC, but I need to finish whats on my plate first!

Anyone have a blown/junk Rotrex charger laying around? If I had that, I could try passing the bracket design off on Brandon.. he would probably be interested in the project.

I'd be first in line for a phunk-improved gtm-esque setup.

Count me in as well

I can imagine the whine with the VQ behind it.

Awhile back I wanted to do this.

I was expecting that to be wayyyyyyyy faster :ughdance:

You are in luck!
I blew mine last month, will PM you some details and getting it to you.

Lol. I did this. Except I used the powerlab kit. Then that guy did too but over in Germany. We were both on stock DE blocks. His grenaded shortly after. I put about 7K on mine then sold both kits and the car to buy the 370.

The whine was toned down a bunch by having the intake muffled through the turbo. But before that with the stage 4 pulley you could hear me coming from 4 blocks away with no exhaust note.

If GTM folds I can have the 4 brackets that mount the supercharger/alternator/power steering pump reproduced. If some one else can cover the intercooler and charge pipes. I also have canned tunes for the 1.0 and 1.5 setups. Last I would go the factory Rotrex pulley system.

I really like Whipple!

Yesss yesss, I would love to see a nice kit using the Rotrex units.

Pokeyl, are they able to produce the same pulleys that GTM used?
Trying to source an 88mm but want to make sure it will bolt up & line up correctly with what GTM designed. I know the standard rotrex pulley is a 4 bolt but GTM & other kits use 6 bolts for the pulleys.

I spoke with Phunk, depending on schedules & when my car goes under the knife for SC repairs I will be sending him my broken SC unit.
This way he can look at what GTM has done with their kit & then make changes as needed if he wishes to produce his own kit in the future.

JTran built me a custom pulley for my Stillen supercharger. I'm sure they could do the same for you. They just took my 3" as a template and made me a 2.5" that was identical.

I am thinking of having the car towed to them once I get some parts ordered & build time lined up.
Going e85 so will need a new tune done also (plus redo the 93), and running new fuel parts which I don't want to deal with.

So is it at 90% done yet?

As an update, i got the whipple in last week. Installed it to the mustang over the weekend.

As for it fitting the VHR... NO WAY NO HOW! The blower itself wont fit, let alone with any sort of intercooler. Before any sort of intake manifold or anything, it already pushes the strut bar up an inch.

Maybe a smaller PD blower would, but not this giant.

So what blower do you think we could fit on w/ a mani and ic that would give us 500-600whp?

How many liters of displacement would a PD blower need to see for it to be a good match on the 37vhr?

I dont know if I think any blower could fit honestly. There is 4.25" between the strut bar and stock lower intake manifold. At that plane, there is about 6.5" of clearance between the valvecover hardware. My whipple is 5" tall bare headunit, before any adapting plate. Its about 7" wide at the bottom flange, and about 8" wide at its widest, not including the gear box. But this is also a 1000hp+ blower. I am sure you can go way smaller.

If you removed the lower intake manifold and went straight to the heads with ultra short runners.. you could maybe work out about 2" to 2.5" worth of vertical plenum space and intercooler space, it would be really narrow and small displacement.

Then you still have to get a pulley attached somehow. You cant go through the timing cover opening on the HR/VHR because the water return pipe is there. So you have no choice but to go over the timing cover. Adding the radius of the pulley over the timing cover and offset of the jackshaft combined and the pulley is going to be through the hood no matter how you slice it... Not sure how much, but I would guess at least an inch.

Theres only 2 realistic ways to work it out... 3D scan the engine and a couple potential blower candidates to see if you can make it work at all... or buy a blower or two or three and plop them in there and measure around... but thats risky as you could find yourself 100 hours in before you realize it wont work. The 3D scan method is the only way I would try and tackle it with a PD blower. I feel its just too tight to wing it... but I would never say never.

*cough*centrifugal-type*cough*

we want it... you can build it... let's make a deal :tup:

Phunk, Why did you go PD over centri on the stang? Have you driven it yet with that monster whipple? Wondering how it compares to your TT370.

When my intake manifold is done, I can start looking at that more seriously.

I havent driven it yet, working out fuel and tuning this week. Should hopefully be on the road this weekend.

Its going to be a handful, the car is still on stock wheels and tires and all my Z stuff is too aggressive offset for the Mustang unfortunately.

I already know its going to hook up a lot better though. I can tell... even screwing around on the stock rubber and stock engine I could feel that this cars IRS is configured to give it more straight line grip. I think that on some drag radials, its going to demolish my Z as far as 60' and quarter mile, simply due to grip. Power to weight will be close, I expecting to make around 720-740rwhp and of course the Mustang is a lot heavier car.

The Mustangs that get the same trap speeds as my Z, get about 1 second quicker ETs.

Yes but it would costly, the rotrex pulley easy to get

I have a deposit on the gtm kit that is in the fs forum. I believe he said it came with 2 pulleys what size do you need?

I need an 88mm pulley.

looks like this company is GTM.

:rofl2: :rofl2: :rofl2:

New here?

No. I think he read the post about their roots setup. Odds of that hitting the market sound bleak however.
