Drivetrain Sprintex
Spent this afternoon data logging and am now waiting to get final or should I say, the next tune from Mynes. Once I get that back from them and load it, it'll be time to go and give her a proper flogging... er - I mean brake-in.
"****'s" has a video clip link you can hear on his build thread.
For me the wait is bad enough, the real problem is going to be the restraint to be clear headed and not get into too big of a hurry during the install.

I'll try to get some audio/video in the process and post up here. Stay tuned.

I'm secretly working behind the scenes on a new airbox (pannel filter type) that shuld out flow the ALTA system thats on the car now, and make some more noise.
I'm still measuring all of the littie pices so I can make it as big as possible and still be able to seal to the box top that I made. Its going to be a lot of welding, but hey If the prototype works somebody might be able to pick up production.

The GoPro was mounted on top of the windshield with the open back on. It really didnt pick up much exhaust noise, but some wind. Crank it up!

Dont forget to update the SPRINTEX OWNERS LIST.
I forgot to ask if you did anything with the inlet pipe? Ive been doing some thinking and If extra money permits while my car is down, I might try a new design. The water pump would need moved, and I would be relocating the Throttlebody closer to the airbox. Also would need to reroute the bypass valve a bit. I need to stop thinking, no wonder I'm always broke.

I keep playing it over and over!! Love the sound! Sounds really tight! Not hollow and loose. I also like being able to hear it at all RPM, and when you get your foot in it, it like a jet turbine spooling at start up..
Thanks for the clip

What could I expect results wise, realistically? My car currently has the following engine wise:
1. RMW/Newman street cam
2. RMW Shorty Street header
3. Milltek catback
4. 3% OD crank pulley
5. Alta-n-ator
6. JCW airbox/Alta JCW filter/Alta silicon inlet tube
7. JCW injectors
8. Haltech Interceptor + tune
9 15% U/D SC pulley (would come off)
10. Alta DFIC
11. Brisk racing plugs
Car makes 151kw at the wheels on a dyno-dynamics dyno in Australia...(read into that what you will...I know there's a lot of discussion about figures from different types of dynos...)(conversion to HP is 205 whp)
So, if I were to buy the sprintex, with 64mm pulley, realistically what could I expect?
Would I need to get a headjob to climb above my current figures?
Also, does Sprintex have an Australian vendor? doesn't make sense having to ship a Aussie product back from the US...

Honestly that would be just a guess, here are the test results on a vehicle similar to yours. (don't know what the whp conversion is.)
Sprintex S5-210 unit.
TPR1 Ported head with matched Intake Manifold. (very mildly ported)
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.
I don't rember which pulley this was 64mm or 60mm (maybe someone else would know)
Also if I rember correctly you would probably go back to the stock diameter crank pulley and I would suggest larger injectors if you don't have them.
As far as a vendor, just contact Sprintex through their web site and ask them.
Oh, just got an update on mine, sched. delivery to me 09/22.

Pretty sure the data you put up was Mynes green car with the 70mm when it was first done.
Yes you would want to go back to the OEM size crank pulley, stock, ATI, or fluidamper. The ATI seems to hold up the best.
As for what you would get HP wise, I couldnt even begin to guess right now. Thats the reason for the Sprintex owners list. Right now the kits are out there, but we need more individual results, to make more educated guesses.

I'd love to have a gilmer belt/pulley setup to go with the sprintex!! Even if it were the same width belt as stock!

I brought up a cog-drive belt system before the Sprintex kits where even released.
It is really un needed acording to everyone, and really not worth the expense of producing the setup. You would need to make the crank, A/C, and alternator pullies along with the S/C pulley, that eaquals lots of $$$. The only real bennefit from it would be that you would never under any circumstance get any belt slip! It would be great for the track, but not verry cost effective.

For example when I lived in Melbourne some of the folks in the pubs would find it hysterical that announcers for some American sports would say "there are all the fans in the bleachers - rooting for the home team"!

After reading all the pages, all I can say is wow. I'm all for Bytetronik and Sprintex. I think the $3195 price is not bad when considering it comes with a electric Davies Craig water pump($$$), but I think $2999 would be a better price for the MINI community and me.
Also anything that allows an open market, that allows you to use any tuner you so fit to tune your MINI, and with a supercharger that's not somewhat proprietary to a shop like Rotrex(to RMW) is good for everyone.
Say no to MINI tax.

Hi Guys,
Update from Holland here
Another one on the list!
I am about to receive my Sprintex charger and will be building my engine from that moment on
ATM the list of building is:
Sprintex kit
Thumper TPR2-R head
Thumper Intake Mani
Newman 248/396 cam Ph1/2
NGK BCR8ES
Bosch 550 cc Injectors
Dave.F Hybrid Airfilter (slightly better than JCW's)
Samco inlet Hose
GRS Motorsport Version IC
ATI 1% Crankpulley
Janspeed Mani with 200 cell cat
Milltek CatBack system without center resonator
1320England Mynes tune
I am in the middle of thinking which pulley to stick onto the Sprintex.
The 70 mm one is not an option as I am looking at the best power achievable. The stock lower engine will be kept as the stock Mahle Pistons and rods are capable enough of handling big numbers of HP
Will a 60 overblow it with my 1% ATI pulley? Or could it be done if I put a different alternator-pulley on? Or would one say, the 64 is the best (say safest) option? I check my oil every week, cause I already had to switch engines once because of bearing failure due to low-oil-levels. That aint gonna happen again. Tuning will be done by 1320 who already have experience with the Sprintex and scaling the 550's. Gas here is always octane 98 so the running-lean should be taken care of. The breaking in period for a couple of hundred miles will be done easy on the gas as I have to drive to England on my 380's so no revs over 3500 and no WOT. Those couple of hundred should be enough I guess to break in the head and SC unit..?
Temps are not a problem here, I am at sealevel and most of the year it doenst even go over 65 degrees
What WHP-number would I be looking at with the suggested mods and possibly a 60 mm pulley?
Thanks heaps guys! Already been a lot of information for me here!

Welcome, I see you've already found the owners thread, if you look on the "other" board you can see some peojected #'s but no-one has done one with a BVH yet, so we really don't know.
I took my car to "service mode" after work this morning after work and should get everything else off when I get home today (hard to get things done with 13 hr work days) my kit should aririve either today or Thur. but still have to get parts out & back so final assy. won't happen till late next week or that w/e.
Hopefull I can get everything broke in and get some #'s soon after.
