Is RMW selling it since we tested it?

So a yes haha Looking forward to updates with what you have in the pipeline also

 

[dreammaker]

it would be better if i had not spent 20 pages to read so many irrelevant stuff.. anyway.. the only real data as far as i have searched come from mynes testing on the sprintex..
i post the data as i saw them..(these data are from sprintex stage II kit and they are really interesting and tempting! also the kit is really professional.. looks like stock! not to say better! lol)
Paul have done any further testing on sprintex kit?

as Mike said:
"Ok, finally ran some more testing on the Stage II kit and here are the results... the mods on the Green test mini is as follows:

2006 MCS Manual, stock ECU, stock 1.6L (stock pistons and rods, stock compression), stock clutch, stock tranny, stock intake, stock coils-pack and wires.

Modifications:
- Sprintex S5-210 unit.
- TPR1 Ported head with matched Intake Manifold.
- Mynes V2 header with factory CAT.
- MegaMINI Cam shaft.
- GP Intercooler.
- Bosch 550cc OE Injectors.
- Nvidia exhaust.
- Bytetronik FA53 Tuning Kit.
- NGK BKR8EIX Spark plugs.

Baseline:
On the M45 stock supercharge with the 15% reduction pulley, it put down 219whp / 177wtqe.

Sprintex Stage II kit:
On the 91 octane pump gas, car put down 243whp / 197wtqe.

Remarks: Being in California, the '91 octane' we get at the pump doesn't really provide the actual potential of this super charger. For guys in areas where you have access to higher octane fuel, you should hit 250whp without any issue.

On E85 fuel, we were able to get the power level up considerably: 266whp / 220wtqe.

Here is how the dyno graphs look on the S5-210 kit (91 Octane vs E85 fuel):

Here is a comparison from the M45 baseline to the S5-210 with E85 (max potential of the Stage II kit as tested):

Here is the comparison between the M45 and Sprintex (both on E85 fuel):
Note: the M45 on E85 was done prior to addition of the Thumper head. We didn't have time to test on E85 with the M45 after the THumper head install. So the Sprintex HP and Torque is aided by the addition of the Thumper Stg I head and Ported Intake Manifold..
=> M45 : 228WHP / 187Wtqe
=> Sprintex 60mm: 266WHP / 220Wtqe (aided by TPR1 + Ported IM)

Triple Overlay:
Top one: Sprintex on E85
Middle graph: Sprintex on 91 Octane
Bottom graph: M45 on 91 Octane.

Power Progression from M45 (area in blue) to Sprintex (area in yellow):

Ok, finally got all the data logs organized and sorted. They have been added to the original post as well:

4th Gear dyno with the 16 PSI Pulley:

4th Gear dyno with the 19 PSI Pulley:

About two weeks ago (March 2011), we had a heat spell here in Southern California and the outside temperature was 95-F; so while cruising on the Freeway, did the following two logs (5th Gear and 6th Gear)...

Note: Even when the outside temp was 95F, the IAT was under 51C cruising at 80 MPH. No over-heating whatsoever Wink

Test Recap:
On almost 270whp and 220wtqe, it's shocking for me to say this, but the car is a little scary to drive in its current form without upgraded clutch, better tires/suspension and definitely needs a good LSD. So before we move onto Stage III testing, the before-mentioned parts will have to be upgraded before we make any more HP.

In 1st and 2nd gear, if you give it more than 30% throttle, the front tires will just spin continuously. By the time you get to the top of 2nd and going into 3rd, that's when the wheel spin stops. The power is awesome and the 220 torque is definitely noticeable. Even while passing in 6th gear on the freeway, instead of having the need to down shift to 5th, one can simply give it a little more gas and the car will scoot and go...

We know from testing the S5-210 on the Jeep that this Sprintex unit is definitely capable of producing 300whp (b/c we actually got 300whp from a Jeep Wink... so the factors that are limiting the full potential of this SC are other parts.

So for Stage III testing (which will be "on-going basis"), we will try the following mods (utilizing the Stock ECU):
- TPR2 or TPR3 Head (Thumper, we need to talk when you get back from vacation bounce )
- W/M system
- bigger fuel injectors
- upgraded Suspension and brakes
- OS Clutch and OS LSD

Thus far, we have run into no over-heating issues. Even on back to back to back dyno runs, the car produces very consistent HP and wtqe (if the power go down by 3HP, the Torque comes up a couple; and if HP goes up a couple, the Torque goes down by a couple). The Max HP produced in Stage II test config was 270HP, max torque was 220.

Will post more data and data-logs from the streets and freeway driving. The past few days got up to the 98F temperature and we have those logs to share as well. Overall, very nice setup and i'm keeping this Sprintex on the Green MINI permanently cheers


and here is the production unit:

it looks a state of the art!

That'll be nice with some nitrous added :thumbup1:

"Even when the outside temp was 95F, the IAT was under 51C cruising at 80 MPH. No over-heating whatsoever Wink"

not much good in the uk if you cannot do "motorway speeds" without temp clipping
and the last table looks to be kissing that number when the foot comes of the gas? time in seconds?

being at 16 psi + for any length of time in 5th gear quickly gets me into tripple digit speeds,
and by 120mph+ then temp clipping?

i am confused as i expected to see cooler temps as the key behind better bhp
the bost figures do not look that much better with the base pully
and if the 19 pully ramps the temps up that quickly you left with a one trick pony?

 

[ADAM]

I think people need to factor a few things;
the charger is smaller than the stock but still outperforms it
To fit as a direct replacement will cause limitations ,mainly space and hook up to the throttle in it current position and intercooler

Its limitation is not the charger system its buyers budget !!
Did you get any vacuum numbers in the S/C inlet? It looks restrictive to me (due having to link to OEM) this will rob power and a fair amount too .
A larger unit would make lots more but higher costs would mean only a handfull sold , however this size unit can still be pushed harder with water /meth .
If injecting water pre charger ,only a small amount can be used as any fine spray will coalesce passing through the charger and form larger droplets as it contacts the rotors and sidewalls at relativly low speeds so lose effect quickly within the charger .
used on the outlet end(in addition) however you could remove the intercooler or gut it completely ,gain some boost and offset det allowing higher boost -much higher boost ,but water dependant .
Looks a well made kit and another option becomes available well done , it also gives a springboard to larger units for the couple of people who would demand much more power and have coin

1) Here is a data log from a M45 with 16% pulley and de-CAT header with STOCK injectors at ~14.5 psi (outside temp 60F) - Street Run log provided by FA53 customer:

2) M45 with 15% pulley on 450cc injectors done on the dyno:

3) Here is the data log from the Sprintex at ~19.5 psi (outside temp 68F) - done on the dyno:

The S5-210 is actually equivalent to the M62 in power output. This same charger is capable of pushing out 300hp (which is already proven on the jeeps).

the S/C inlet is indeed a restriction to the system. This is the trade off that Sprintex made due to the OE Replacement Application. There just isn't much room in there to do anything other than the OE shape w/o going all crazy.

Quite honestly, having 270HP/220tqe is quite scary for a street car... It's a totally different animal :lol:

 

[Lee]

m45 logging starts at 45c inlet temps
sprintex at equivalent m45 speed starts at 30c inlet temps

5700 - 6700 rpm the m45 IAT's rise 11c in 5.1 seconds
5700 - 6700 rpm the sprintex IAT's rise 5c 1.65 seconds

91 - 107mph the m45 IAT's rise 11c in 5.1 seconds
91 - 107mph the sprintex IAT's rise 8c 1.8 seconds

Explain...

You could add a pipe as an aux throttle to the inlet pipe that is vacuum opened with a separate filter - so it is only used at full throttle to reduce vacuum
or move the throttle on to the back of the charger and extend wiring leads and reroute bypass - not much room though and less self fit - you do lose LOTS with inlet restriction!!
With rotors cooled the charge rwill really punch above it weight !!

We are here to present the data as we collect them, you do what you want with it.

This is probably linked with the boost pressure , note the M45 boost rises at the high rpms , the engine is choking and pressure rises , so the back pressure on the end rotors is increasing , heating and turbulence , leads to ever increasing losses - over more time these would go higher -
the 2 screw has its boost dropping at the higher rpms as its internally compressing and its intake vacuum is increasing lossing efficiency

Very helpful thanks. how is there such a big discrepancy in time taken for 1000 revs / 16mph? Sprintex cant be that much faster.

It would be interesting to see how it responds to water meth - considering on an M45 it aint a big power gainer

 

[ADAM]

The m45 is not a compressor

 

[D-MAN]

^care to speculate on the sort of gains hp wise would you see?

 

[ADAM]

Keep punching in water/meth to cool rotors and cool compressed air , (this would need a complex multipoint injection to keep spray as mist) and keep upping boost until either rotors sieze or engine dets ( also dependent on other engine modification)
I dunno I guess circa 30 psi possible , so you can calc from that
be easier to use a bigger charger at some point -

 

[D-MAN]

^ so 300hp should be doable with water meth....

 

[ADAM]

@30 psi a lot more than that !!!:lol:
