Just ordered my Sprintex, my w/p gears on my M45 are finally gone, in my case it worked out to be about an extra $1600.00 or so simply because I would have replaced eveeything that comes with the kit anyway had I rebuilt my M45. (because if the cars milage)

And yes I want more HP, and with my mod's there aren't really that many, if any, more mod's for that amount of money, esp. with those potential gains. Only time will tell if it will be worth it or not, but I'm hopefully optomistic.

Oh and I bought the 64mm pulley kit up front too.

 

Oh YEAH!

I'm sure that Rick and Gary will have it shiping out to you soon. I cant wait to see what it's going to do with a BVH and NS2 combo. Are you doing the install yourself?

 

Yup, gonna give it a shot, honestly the only one who's been under the hood besides me is Chad and I'll still leave all the serious engine work to him, but with the distance (600 miles one way / 10 mpg in my van round trip + trailer rental) I figure it's worth a shot, esp. since it's essentially a bolt on item and I've heard good things about the kit being very complete and still retaining a very " it's just a straight swap" type feel. + I've gotten a tip or two from people who have done it.

Besides, worse case I just can't do it, throw it on the trailer and take it to D/T anyway.

(I have my Bentley, my Torque Wrench and my Play School Tool Belt ready and waiting!).

Regarding the BVH &NS2 thing my car works REALLY WELL from 5000 and up and ultimately HP is the goal, but one of the biggest things for me is what I've been hearing in regards to mid-range power and torque, to me and my style of driving that is what will really make it fun and worth it.

 

Sounds like a wining combo! Install is verry straight foreward, just remember to read the instructions. And when you collapse the tensioner make sure you do it slower than a sloth would. It colapses easy, but the innards are held togeather with one little snap ring that likes to pop off if you go too fast.
You are still going to gain quite a bit up top but, a big bump around 3K, are you going to do a before and after dyno? If you are I would wait about 500 miles after the install, just so the blower can go through its break in an get a good seal. It took mine about 300 to get to its peak boost.

Break in shouldn't be an issue, 75 mile a day round trip to work.

As far as a before & after I wish, but the W/P gears are so loud I'd be lucky to even get it to the dyno let alone run it. The only thing I have to go by is from spring of 2010 right after the NS2 and RMW header install, got 235whp with an O2 sensor that was bad and making the tuning difficult, just from the butt dyno I can say the car was running better or at least the same right before I stopped driving it last week. (Oh and the 235 was with only 13.5lbs of boost, I had never changed from the JCW pulley.)

I will however get it on the Dyno once I'm done with the tuning.

 

Since we're neighbors and I'm handy with a wrench. Let me know and I'll come up and help

 

You remind me of someone on this board. Can't put my finger on it just now. Oh well, I'm sure it will come to me.

Companies that claim many and produce inferior products will go under. Sprintex has been around and has made/designed products for other makes with good success. Mini application is just one of their latest offering. Reputation builds success. This is a multi-million dollar company and not a backyard company that sub-contracts its manufacturing and engineering or rebrands other companies' products. Guilty?

 

I'll shoot you a PM when the parts come in.

 

There are NO issues with heat and the final production Sprintex kits. Yes durring testing way back in the day when BoosTec was working with RMW on prototypes, well before Sprintex took over the project, there where some issues. Most of theese where caused by excessively overstraining the S/C (Trying to push 22psi of boost out of a rough designed prototype that was cobbled togeather with spare parts.) and a "tuner" that thinks he knows all about everything. Those initial failures is where the line of broken parts stops. So far there are more Sprintex kits on the streets/tracks around the world in less than 6 months of production than there are total for the Rotrex, or any other replacement S/C kit. So far out of the 100 or so kits that Sprintex has sold WORLD WIDE, only ONE car has failed! And it sure as hell wasn't because of the S/C, I would know because the broken car is in my garage.

I actually think that its funny that you need to bring up different types of aluminum to try and give this product a bad rap. Well I can see the usual croud bringing it up since its really all the can do, with the lack of hand grenedes they thought they would have. So manny where on both sides of the fence durring pre production, and the misinformed scared some away but, guess what threre are more and more people starting to lean back tward the sprintex. My only suggestion is, Learn, do more research than just the failures, get the right info on the parts, and once you are done with that, do some research on the people (ALL of whom are involved) that are making the claims good or bad. You might be surprised what you find out.

There will always be a new product, from some new (to MINI) company, it's just the way it goes in the aftermarket world. Nobody can stay at the top of everybody's wish list forever.

 

I avg. about 26,000 miles a year, shouldn't take too long to see if it'll last or not.

Like anything, all I can do is give it a shot.

 

I have enjoyed reading your past threads because they were refreshing unbiased accounts on modding the MINI your way, taking all available opinions and making your own decisions.

Your most recent threads and posts, however, clearly show that you have fallen into the trap of choosing sides in a tuner battle that no one wins. It is too bad, unbiased opinions are now the exception and we have sadly lost yours.

For example, in my opinion, it is very weird that you keep on recommending both the Bytetronik (sp?) and the Sprintex kits when that exact same combination caused a catastrophic engine failure on your car. I for one would never recommend something that caused my engine to blow up. Just me.

Instead of just dismissing criticism as trolling or "fanboism", some people should take a step back and think about all differing opinions and recommendations for a second. Who knows, maybe people might take away something positive. Imagine that.

 

Remember that this isn't sprintex's first supercharger and i would guess they aren't making their own alloy for this specific application. With that not only silicone content would determine the the phases present but also the heat treat (heating and cooling) based on TTT curves for the specific alloy. In addition to that most aluminum alloys get their strength form precipitation hardening adding another complicated piece to the puzzle.

If they haven't had supercharger falling apart regularly due to material selection i don't see it ever being an issue.

end science lesson for the day.

Your source for this info is both out of touch and out of date with recent goings on with regards to Sprintex . We have been doing exactly the testing you are claiming has not been done for some time now as we are in the process of having the Sprintex system CARB approved. To fulfill that requirement the car has to remain bone stock including tune , injectors and even intake with the ONLY change being the SC kit itself. The car has performed perfectly so far and as we are in So Cal there is no shortage of traffic , 91 oct and 100+ days . As you seem to be in the loop with regards to other aftermarket systems you might want to inquire as to how their CARB program is going or are they just going to let their buyers take their chances ?

Not that is is directly relevant to the system designed for the mini but could you provide the links to " other car forum's lots of failures " ? I would be interested to see where the differences on those systems are and ours .

Thanks

Tell him that he needs to come up with something better than that . The car is working very well with the stock tune which is mandated by the CARB process. I think something else that helps with the hot weather concerns you mentioned was that the supplied electric water pump with its after shut down cool off period is really an improvment over the stock configuration. I wish I had something like that on my r-53 as it was 105 here yesterday BTW

This forum exists at least in part so that we MINI enthusiasts can separate fact from speculation.

I'm optimistic that the Sprintex is as good as advertised, but indeed time will tell in the end. Most MINI owners I know aren't shy about complaining if Product X doesn't pass muster, so if the Sprintex SC can't hack it I'm sure we'll hear from BlwnAway, DGR53, and other "early adopters". If Sprintex is indeed as good as advertised then so much the better -- but let's let the facts speak for themselves.

 

I would also like to see theese failures. I talk with Gary at BoosTec (The NORTH AMERICAN DISTRIBUTER) regularly, and have only heard of a tensioner failing, due to an install error. For $100.00 and a trip to the BMW dealer that car has been fixed.

 

Sprintex = good, 80,000 mile of abuse + 7500 RPM, lack of oil, and a factory bottom end with Sprintex power = BAD. You shouldnt need to ask how I know. Live learn (FIX the leaking oil pan gasket while the car still runs) you know how it goes.

 

Link to failures please . You said yesterday you had just learned of Sprintex so it should not be hard to come up with ,thanks in advance

It's still a newer design than the ROOTS (EATON M45, M62, M90 etc, etc) which have been in use since the creation of asphalt.

 

Absolutly, if it fails I'll be screaming bloody murder about it. I've had failure of a well known performance product that many people here use, but kept quiet about simply because it was what I thought was an isolated incident with that piece, but believe me I start having S/C related problems, it'll be up in this forum!
And yes I think my case could be a real testiment to it if it does work, considering the extent of my mods, the milage I drive and the milage on my car, which tends to really scare alot of people away from doing performance mods.
But there again only time will tell.

 

Hey Randy,

I sent a message at your website asking about the warranty. Didn't get anything back yet.

My car spends two days a month at the track. Be happy to document ongoing results. Just want to make sure I'm covered.
