Just for fun: TVS blower idea...

Jordo! · 07-12-2015, 06:54 PM

Yes, it looks like a child (a slow child...) drew it.

But, just an idea for someone to play with if they were so inclined. Obviously some major tinkering with CAD software would be needed to make sure it all fit, custom endtanks for the barrel IC idea (possibly rotated to lay with in and out on same plane?), dual inlet and outlet (probably with an internal separator plate on each to equalize air pressure and flow).

Anyway, just for grins...

Anyone want to try and build it?

You can probably source a MP90 on the cheap instead of the newer TVS blower... the rest is just chopping up an OEM upper and lower IM, making bracketry, etc. Big HE in front, nicely set in front of radiator with careful planning to keep air from ducking around it; big water pump, a reservoir somewhere...

Oh, and obviously a hole in the hood... and some reworking of the front strut bar... hmm. Maybe this is why no one has done this...

This set up would be good for 450+ roots blown, super torquey fun.

Easy, right?

Thoughts?

Johnny6.1 · 07-12-2015, 07:09 PM

I actually have a powder coated, ported and polished mp90 I would b willing to sell from my old car. Both the TVS and mp90 were kinda popular with the cobalt community I was in. TVS is a much more efficient blower though to be honest

Jordo! · 07-12-2015, 08:27 PM

^^^ Definitely -- just throwing that out there if anyone wanted to actually try and do this.

The key innovation is dual inlet/outlet plus internal airflow straightener idea (taken from A.G. Bell's excellent text on supercharging). That should mean equalized pressure to both banks.

It would need a nice Johnson water pump too. And a bigger fuel pump and injectors.

The rest could be cut out of aluminum (bracketry, etc.) or built by modifying a OEM upper and lower mani. Then you just need some mandrel bent 2.25" (for TB to back of SC) and 2.5" piping in.out of IC core). If someone actually anted to do this, I'd help with sourcing parts and checking sizes of things like core, piping, pump flow requirements, etc.

And it needs a hole in the hood. Anyone know how much clearance there is from the head up? The IM/IC core design is probably about as tall... then the SC would have to stick up mad max style...

And it would probably need a different front strut bar...

If I had the cash and a buddy on hand who is both a madman and a good fabricator, I'd be doing this. But... right now I don't, so just throwing this out there to see if it inspires anyone.

Johnny6.1 · 07-12-2015, 08:40 PM

Lol I know the feeling. It's didn't get put on my old car cuz I didn't have time and money to get ir running right with that blower on it. Which size TVS were u wanting to run, 1900? There's also the lysholm blowers too. Would b interesting to c. If anyone wanted to try with mp90 I would b willing to sell mine for cheapish. Lol

Jordo! · 07-12-2015, 10:11 PM

A lyscholm/twin screw would be ideal -- but its also the most pricey. I'm thinking of this as a "bang for the buck" project for somebody who can weld and has time on their hands (sadly, not me).

I'd have to check sizing recommendations, but I think either old MP90 or TVS 1900 would do the job. As its intended to be A2W, you could get away with a smallish core (too big isn't good for flow anyway), then add in a big Johnson water pump and a HE up front -- the one off the Ford Lightening would probably work (I've used it before).

Short piping in and out of the IC core means no lost boost and great responsiveness. 2.5" inelt/outlet piping will be plenty big for up to 450 hp.

Pre-SC piping could be kept OEM so OEM MAF's (so long as they didn't peg at 5 v) would work great.

It wouldn't have quite as much top end as the centrifugal blower or turbo kits, but the off-idle torque would be seat pinning.

Oh, yeah... I forgot. There's need to be a big bracket in the front for an idler pulley and some experimenting with belts. And probably dual catch cans, but a lot of the components could be "parts bin" and then modified as needed to fit (brackets would need to be cut out of aluminum of course).

Keeping OEM lower mani means you can use OEM gaskets and FPIG for the rest.

I've done this before, but smaller motor, and had a lot of assistance with the tough parts...

If anyone checking this thread out is feeling inspired, but dubious on fitting the IC core in such a tight area (understandable), another option would be direct port W/I. So long as its after the blower, but before lower mani, it would work great.

More compact design, but then you need something like this https://www.coolingmist.com/pagedisp...Key=DirectPort (I've done this with great sucess before too

)

Actually, if you do it that way you'd only need to fab a bracket for the SC to upper mani, one for the back of the SC with the intake piping from TB welded to the bracket, and then add in your port water/methanol injectors.

You could run the pump and tank from the rear (or relocate the battery I suppose).

Except for top end power, this set up would absolutely blow away anything else currently available -- you'd have tons of grunt right off of idle, and a flat torque curve like a table top.

The Z would feel like it had a V8, and perform like it too...

(wistful sigh)

Johnny6.1 · 07-12-2015, 11:45 PM

Lol wishful sigh indeed. That would b a nice setup. Yea it would lack top end but there is much more usable power when driving around town.

So I may perhaps know a guy who would b willing to try if someone was willing to put up the coin for it. Sadly I'm in the middle of buidling a house and don't have any spare coin.

But with enougo interest he could maybe fab something up. He did the custom kits on the cobalts

Rusty · 07-13-2015, 12:10 AM

phunk took a hard look at his. It's doable only if you cut the hood and had the blower sticking out.

Yep, I pretty much figured there was no avoiding that.

It'd be worth it, tho'

James10694 · 07-13-2015, 08:18 AM

Like this? Just make it a little bit taller

Z eliminator · 07-13-2015, 08:31 AM

I would take the intake from the stillen 350z set up and make a new plate that fit the 370z lower intake.
the next step would be to mount the blower on top of the stillen intake.
Stillen did put a m90on the 350z ( 2003) but it did not work it was too big>
I spoke to engineer's at stillen who did the project .
the TVS makes a lot less heat than a M90,

Z

TopgunZ · 07-13-2015, 09:00 AM

What? The M90 didn't work? That is what is on their kits, like the one I owned and ended up twin charging because it was worthless. There is no way you would get 450whp out of this blower. It was way undersized for the 350 and even more undersized for the 370. The most anyone got out of it was 360whp so you could MAYBE get 375 out of it with the slightly larger displacement.

But I foresee a ton of issues. First of all I couldn't even go stage 4 with the 06 rev up because it would have overspun the blower. A guy I know had a custom pulley made to go stage 5 and it blew his motor due to nothing but heat. The problem here is that the m90 hits a certain rpm and becomes a blow dryer and falls on its face. I seen this with mine at around 5500rpm. Take this thing up to 7500 with a small pulley and its going to blow fire. The system heat soaks instantly just like the 370z stillen.

If someone actually decides to take this on then give it a chance and don't waste a ton of time developing something you can achieve going NA with bolt ons.

bullitt5897 · 07-13-2015, 09:22 AM

Take a HR hood... Cut the bulge off and install it on a 370z hood... Good clearance issues solved.

TopgunZ · 07-13-2015, 10:36 AM

Will that fit? The 350 hood conforms to the lights. 370 is flush.

Z eliminator · 07-13-2015, 11:12 AM

the stillen kit was a M-62. blower.
I have one on my 350 z , I had it ported and ran 11 lbs of boost. I had custom pulleys made for it.
it made 309 RWHP. base line was 217. (it was a 5 AT ).
I also had headers on it with after market cats. Lost about 15 rwhp.

TopgunZ · 07-13-2015, 12:22 PM

Your right. My bad. I forgot how tiny it was. I haven't seen that setup for about 5 years now. In that case you would get about .28 liters more per rotation with the m90.

Damn dood. You hit 11lbs? That's pretty good. I would have thought you would get more than 309 to the wheels but it was probably because it was running ungodly hot.
