This looks interesting... Sprintex bolt on SC kit. Looks like the Aussie's are making one for 1st gens. Without seeing dyno results from this setup it would be hard to drop 3k on something unproven. Thoughts?

 

IMO, even if it is proven, it would have to prove some pretty big numbers! Like significantly more than a 17 or 19% pulley to justify $3K + install. I don't see a PTO on the water pump. Electric?

 

At first it seems like a lot of money, but if you need to replace the SC anyway, it is a "only" a couple grand. Now, assuming it is adding a bunch of power, I think it is worth a try.

Ian and Jan ran one in 09 I think, and Paul Webster says he will have one in feb to try. Looking forward to seeing this proceed.

Dyno or it never happened. lol

The question is if the supercharger has an efficiency near what the newer TVS blowers have. If its essentially a regular M62 idk how much better it would really be for 3 grand. Granted at the same psi the blower will make less heat than the M45. I was trying to read the compressor maps for the blowers off of Eaton's site to see how much better the efficiency would be but if I am reading it right @17psi (roughly 1.2bar above ambient so 2.2bar total pressure?) we are off the charts...

 

If you download the pdf file it shows a cad drawing of the S/C with a water pump on the the right side. IF it's electric or pto driven It wouldn't bother me either way.

Looks to be a mockup on a pedestal with a dyno chart underneath.

Hmmm now I need CSI style 'pixel creation uber-zoom' so I can read the dyno chart.

 

mmmmmmmm just need to see the #s on gains...the pluse is that u dont need to do any lower end engin mods

 

We have been working with sprintex and will be testing this. So we'll see if it is for real soon enough.

 

good to hear there might be a US distributor if it turns out to be a useful upgrade.

 

Will you try to keep their $3k price point ? I had some friends take photos of the MINI they had at SEMA, but they didnt take any shots of the s/c itself.

The MINI even had TX plates....

 

I would hope 3k is the max. I would also hope it comes with a tuning solution included.

 

Why on earth would tuning be included ? $3k would be DIRT cheap compared to similiar options on other platforms. Especially when you consider the demand for such a product compared to others.

$3k for the s/c output horn, inlet, and some sort of water pump arrangement is an insane deal.

 

Not really man. You can get a supercharger kit including tuning, injectors, and a new intake manifold for a 06+ Si for $3400 from a couple companies.

or a little more

Or for $2000 you can upgrade a Cobalt SS supercharger to a TVS1320

so I wouldn't really consider $3000 a bargain

 

In all your links, there are two things you are failing to considering: 1) Those are off the shelf units from Eaton (LOTS and lots of production on each of those s/c's) 2) They are on more tune friendly platforms.

A better, more comparable comparison would be that of Kenne Bell and Whipple, where JUST the units will run you $3k+. Granted they are larger pieces in general, but there is a VERY large market for those two in particular.

Other things to consider: Rotrex $3k a unit, a good 2871 turbo will run you $1400, and neither of those are bolt on applications, and no one makes direct bolt-on kits (they do, but damn are they proud of their cut and paste skills).

Understanding supply and demand, and why a SMALL company charges $3k for a S/C would help this. Not to mention....who exactly is their competition for something like this ? No one...

 

I have a marketing degree. I don't need a lesson in pricing. My reasoning of 3k being not a crazy deal is the gains. Would 3k be reasonable if the gains are only 20-25whp plus the cost of a tune/tuner and injectors (on top of a tune/injector S dyno)?
You seem to be getting defensive. I am glad a company is coming out with something. I just wonder if the juice is worth the squeeze

 

Yea but $3K is a head and cam, or some folks spend that much on accessories for looks. It is all relative. Each upgrade adds power and some folks like to spend money on go fast things.

As long as you don't wreck, it has value on the secondary market, and if it is rebuild-able (and serviceable...like oil change) that would make it more desirable too.

Not for everyone, and that's OK with me. Have to see the results and need a SC for me to even consider, I am watching though.

 

SC replace from the dealer/install is around $2500 with no gain over stock of course.. Not sure what the cost is alone for the SC from a dealer, but as mentioned there needs to be some decent gains to be worth while even at $3000 plus install.. There are places that will rebuild the stock SC for between $500-$800 and you could spent the rest on head, cam, header, tune...which usually puts out about 250 HP
So how much gain is worth while is the question.. at any given price range..

 

all i have to say is let us know how it works out..... if all is good then im on the wagon

 

Fast forward at 4min 05sec

210hp in stage 1 form
eliminates the stock water pump and the plastic s/charger inlet

 

S0 figuring the car is otherwise stock, they achieved 210hp on a car that stock would likely put down 165hp. Thats a 45hp jump with just a swap. If these S/Cs are anything like others they become even more potent and efficient as you up the booost.

Typically, you will see more gains out of doing a head/cam then you would with the m45 too.

This is exciting stuff IMO.

 

hmm i wonder what boost level them figures are at and what pulley upgrades they offer. also be interesting to see what kinda torque this produces.

 

It's currently on my car (and has been since march or april). Got some video's on Youtube of it. We've been battling a lot of teething issues (belt slip, lots of heat, lack of repeatability of dyno numbers). My Prototype doesn't look much like the Computer Generated image they have on the PDF. We're yet to get it to work well enough to do anything other then post decent looking Dyno's. Real world performance on the track we're still having some sorting out to do as it's not posting the MPH on the straights we were expecting.
Probably best Video we have was a VIR when we got half a lap in before the weld on the intake tube from the blower to the intercooler failed and blew the intake tube off. It made 291whp/257wtq the day before this, but we had issues were every dyno pull hot it made 20-30hp less. It would make the same tq but then fall off at X rpm and fall off at a lower and lower rpm each pull. We never really got to the bottom of why. The suspect was the oiling system in the front case of the blower. I heard a solution was being worked on but never heard anything else.
I had never had the car on VIR before and this was my 1st lap so please excuse the driving and lifting in places I shouldn't have lifted. The Ferrari F430 I was catching Ran a 2:02 that session. (I doubt we'd have gone that fast but a 2:04-05 was what I was expecting).


Video of it Dynoing and showing the new intercooler and intake we fabbed up after the other failed.

 

Spoke to the guys at sprintex just before christmas... they say a 40hp gain on a stock car with no mods.
With a head/headers/exhaust they said over 280+ hp

 

280 at the flywheel is meh, you can get that with the M45 and head, header, cam, injectors, tune (of course, but you would need a good custom tune after a sprintex swap too).

280whp on the other hand is impressive, much above this and you should be upgrading internals. There is definitely a limit on boost even if it does run much lower IATs than the M45. I am gonna guess somewhere around 20psi. I am sure Way has some info here.

It is great to have options and looking forward to Way's results, it would awesome if this turns out to be 'the one'.

 

280hp(~235whp) without a head would be pretty decent. If you need a head to get to that level...oh boy :(
