M7 Tuning

 

I had no idea that there was finally a SC replacement. I remember a lot of talk about one or two over the years, but I don't think anything ever came to mkt.

Do you plan to use that "new" Bytetronik software?

Someone earlier mentioned Kenne Bell and Whipple. I had to go check, but I don't see where they offer anything for us. I know they didn't before...

For the most part, this car hasn't attracted the interest of such companies from day one. It seems that most of our aftermkt offerings are from smaller outfits; so I see no reason to knock this Sprintex blower, at least for that reason.

If the M45 lasts 100 to 125k miles, as someone said earlier, the upgrade cost is essentially the Sprintex cost, minus the price of a replacement M45. Appealing way to look at it, for those with older cars / sc's...

Did some Googling to learn that Sprintex is relatively new with applications for several cars this year and a couple years back. I suppose that is why they are not so well known at this stage... I personally like that they are in Australia, where heat can be brutal. FWIW, they claim to have the most efficient SC in the world at nearly 84% and over 80% across a spectrum of speeds...

Hopefully we'll get more data points on this upgrade option over time. I just think that's it's pretty cool that we finally have an option to scrutinize!

 

I'm already useing the Byteronik F/A, so yes it will help with the tuning, but I understand that it's really not ness. if you stick with the stock 70mm pulley, going to the 64mm is where it is needed. I'm doing this as a Performance / Maintenance mod the kit with the stock 70mm pulley is to be a direct "maintenance" type replacement with some added performance because of the S/C's efficiency, basiclly the same as the M45 as in:
Stock pulley 70mm = warranty and all
64mm pulley = no warranty added performance (same as if you do a 15 or 17% on theM45
60mm pulley = no warranty more performance but pushing the limits (ala 19%)

Approx. boost levels are as follows:

70mm/69mm ~ 15psi (stock w/ kit)
64mm ~ 18.5psi
60mm ~ 19.5psi

Which are actually a little higher than the M45 but also with added efficiency, so yes it's promising, and as I said before only time will tell. Myself and a few others are just willing to give it a try.

And yes I would have loved to be able to wait for the TVS to have something to compare but can't just wait around while the car's broke down, I'm figuring the TVS is at least a year out, and as far as the Rotrex, there was only one person offering it and with all the tweaking and specialy stuff involving the install it seemed to me if you didn't live in the area it would be a Major PITA up front, no matter what, at least the Sprintex offers a chance of being fairly simple, not to mention the higher expense involved with the Rotrex.

I figure it this way.
New M45 + W/P + Tensioner & Idler + 15% pulley & Belt = about $1800 to $2000
(least expensive)
Sprintex with all those parts & stock pulley (basicly the same boost) = $3200
(Mid price)
Rotrex = ?, but more expensive than either and I don't live in CA.
TVS = Who knows when or how much.

So I decided to take a gamble, hell when I had my BVH done there weren't that many out there and that was far more than $1200 (difference in price to M45 replacent) and that turned out OK.
I really don't see the big deal?

Hell, who knows, I might be completely insane and out of touch and just want to try something new. (like I've never done that before....oops thats a whole different website.

 

Hey where did all of Because Ricecar's posts go? Guess sneeking around using an alias dosent pay afterall.

Looks like Sprintex holds its own again... Back to being a slow thread for fast cars until the next knuckle head pops up.

Maby we should make a list of Sprintex owners, and have their impressions and individual results. This way anyone intrested wont need to sort through the BS, and will know who to go to with questions.

 

Richard, with all due respect, you keep pushing the Sprintex, and Byetronic...And your car blew up. We still don't know exactly what happened to your car, but will this be included in the "individual results"?

This has almost become a personal crusade you're on (and now you're creating yet another thread). Initially I admired what you did with your build thread, but at this point, IMHO, you're pushing the line of irresponsibility, pushing people who know even less about tuning than yourself to go the bytetronic route (I am not criticizing bytetronic itself, it definitely has it's place for the RIGHT individual who knows how to use it, but for those who don't, it's less than ideal, and these are the exact people you're recommending it to), and pushing people toward the Sprintex, which, along with your tune, just may very well be responsible for your car's current residence in purgatory, Hell, or Gary, Indiana (the only place I can think of worse than Hell.).

Enough already. I don't understand why you have such a need to vindicate the Sprintex. You dismiss what I think are legitimate concerns concerning everything from reliability, boost with the reduction pulleys, warranties, etc. Let it play out. There are some people who have now put it on, without an agenda. Let them have some air time, once they've had some time with it. When you car is actually running, then maybe you can contribute to it as well.

 

Well said cct1, he sounds like a broken record

 

Sorry you guys feel that way. I am still an equal oppritunity modder, and if somebody comes out with a better product for a reasonable price, I would gladly try it out. Sprintex is the only option out there that fits my price range, while keeping all my other mods so it made sence. ByteTronlK is the only DIY tuning tool out there for MINI's. Thats something I have wanted since long before I was on this forum. I might come off to some as pushing theese products to some, but they are viable options for everyone, as is the Rotrex and a custom tune from a tuner of your choice (Jan, Way, GIAC, etc..) I just let people know their options. I do kinda elaborate more on products I have experiance with, but anyone would do the same.

As for my cars engine failure, I seriously doubt that either of theese things played a major role in it. I have had a leaking oil pan gasket for a while that was getting worse right before it broke. When I drained the oil to pull the pan and find my problem it was more than a quart low. The bearing that failed definitely got hot at some point, which is normally lack of lube, and just gave up. Not to mention the way I drove the car when it was running. 80,000 miles of prolonged high RPM canyon runs, 7000 RPM shifts on a daily basis, and just beating the crap out of it for no good reason, are more likely the cause. I was running a bit lean the night it poped, but you get that with E85, its normal for your AFR's to fluctuate using this fuel. So that might of played a part in it too. Still not ByteTroniK's fault, its just a tool. ByteTroniK wont do anything the guy with the laptop doesnt tell it to do, so if theres blame to be had here, you can put that on the opperator (AKA ME!)

Thanks for putting me in check guys.

 

These are combustion engines we are dealing with. That being said there are cars with way less done that have met a similar fate as ****'s. I don't know him personally but I like his ideas and he sence of adventure for boosting a car then tuning it for e85. My car has minor mods but if it blew tomorrow it wouldn't surprise me due to the way I drive it. If anything he is an innovator in mini tuning.

 

Ha it won't let me post ****'s

 

As far as I'm concerned ****'s G posts have been informative and i applaud his enthuiasm. If it weren't for enthusiasts like him posting here we'd all probably be content with a CAI and pulley and never push the performance mods. So, for me, keep on posting Dicks Garage.

 

Don't know if this has been posted or not, while chomping at the bit waiting for the Fed X man I ran across this about the basic differences in the two S/C's, and yes it's from a "vendor" website so take it for what it is.

http://kennebell.net/KBWebsite/Commo...romcatalog.pdf

 

It's all well and good him posting the way he is, but look where his car is at now......Being rebuilt. Lets all go that way and all blow our cars up with him hey If the Full access was so easy to use every man and his dog would be at it and tuners would be out of a job. I personally think it was irresponsible of Mynes to release such products to the general public. Not everyone has the knowledge to do it and personally I wouldn't try. That is why mine was done by a professional and it still runs today.

People will always be sheep and follow others, lets hope people wake up before they all need to rebuild their engines .

 

Ok, let me dummy this down a bit to see if I understand,

You're saying that the tool and tool suplier are at fault for the way the operator of that tool chose to use it?

Nope, stilll don't get it?

Honestly, the F/A software is pretty easy to use, how you use it IS the difficult part, tuning newer cars is a skill and not everybody can do it, all the F/A does is give those of us who want to learn and experiment, the opportunity to do so. Nothing more, and I can't speak for any of the users but I was fully aware of the risks before I bought it.

Also if you read "****'s" posts in his build thread you'll rember that he had a bearing failure, the only thing I can see involving the use of the F/A was giving him the ability to possibly push his machine past it's limits, and even that would be questionable with that type of failure.

I really don't understand the squabbling, as performace modders this is what we do, we push things to the limits and see if we get lucky or not!
Personally I applaude the Mynes's, the RMW's, the ABF's, the M7's and all the others, including the individuals who risk Time, Effort and Money to test and supply us with all of these parts, tools and knowledge, good, bad or otherwise, it just makes my endevors easier and a lot cheaper not to mention just plain possible. Hell I'm a little older and I can't remember all the times things have gone wrong, no matter whose fault, when it comes to car performance.

Besides all we're doing is sharing our expieriences, it really doesn't matter that much when you really think about, this is supposed to be fun, remember.

 

The tool itself isn't at fault. The tool in the right hands, ie someone with more than internet knowledge of tuning, is fine. The way the supplier marketed the tool is an issue. It's not as easy as it was made out to be. Want proof? The original supplier basically sold it as an "easy" way to tune, so easy that they'd help with maps. They now charge for new maps. Why do you think that is? There are people who have bought it who are still struggling figuring out how to tune, after months with it. Just read the thread.

The bearing failure was the cause of the engine failure. What was the cause of the bearing failure? There may be more to it than just AFR's...

I enjoyed Richard's build thread--but it was only HIS car that was at risk. I genuinely felt bad when things went south, would not wish that on anyone. What I do have issue with is the amount of promotion going on for things that aren't as simple as people are being lead to believe. The MINI crowd are suckers for performance mods--any honest vendor will tell you that--and are willing to believe damn near anything because they WANT it to be true. I've fallen into that trap myself at times. We do a disservice to the rest of the community when we push things on people who aren't necessarily ready or able to implement them simply because we love the product.

I do agree with your last statement--it should be fun. But it should also be safe, and that requires a certain objectivity that has gotten skewed badly.

I'm off my soapbox now.

 

This post right here tells my you really need to learn how to tune...should have before you started trying to self tune. Then you tell people lets share tunes so we can help each other...worse idea you have had. Im not trying to be a **** but you have a lot to learn...

What is a little bit lean for E85? Was it 13's if so that's lean. Was it 12.0 or 12.3 if so that's not lean. That's the power range of E85. Also I dont know who told you it fluctuates using this fuel. I have tuned lots of cars that have held 11.8-12.3 where ever I set it. Did you scale your injectors 30% back in ECUflash(this is the program you are using, incase you didnt know). Did you set your scaling right in your datalogger? What are your STFT and your LTFT? What were your IDC's?

Also you need a dyno to tune E85 or at least a power program like Virtual Dyno. You have to tune by HP its making. It will make 3-7hp per degree when you get to that point that it makes 1 or 0 per degree you have reached MBT. Back it down a couple degrees and you are good to go. If you are trying to tune by knock you are doing it wrong with E85. Also E85 doesnt like lots of timing at peak TQ. It also doesn't like rich 11.0-11.5. This is rich on E85 with a gas wideband.

I commend you for doing all your own work, instead of relying on everybody else but somethings are better left to people that know what they are doing.

 

I understand wanting to push things to the limit. This was not pushed to the limit this was a case of a self toooner that didnt know what he was doing. I like the idea of the software. I use this type of stuff all the time in my tuning. Just should learn what you are doing before you go to tuning....especially on E85 and a higher power producing supercharger.

 

OK now this thread is getting sidetracked.

Enough about my car and how it failed, we can have that discussion elseware. This thread is about the SPRINTEX, not ByteTroniK, or blown motors. I DO still have a lot to learn when it comes to tuning, but this is not the place to talk about it.

 

No offense but I'm still not sold on the idea that the tuning caused a bearing failure, thats why I made the comment about "pushing the limit", I would think all the tuning possibly only brought out an already weak point in the engine, and yes without pushing that limit it may or may not have surfaced, nobody will ever really know, if it had been a failure in the combustion chamber or even a rod then that would be different.

As far as the extra HP from the Sprintex it's really not, most of the extra HP is BECAUSE of the Sprintex, it's not forceing more HP as much as it's allowing the motor to make it due to the efficiency if the unit, not extra boost. There are hundreds of Mini's running around with 15% pulleys that create the same boost as the 70mm "stock" pulley on the Sprintex, qith no issues at all, and as far as the 64mm pulley it's basiclly not much more than a 17%, probably very close to a 19%. I personally don't see the S/C being an issue, when the debate first started on this the only real question was would the unit "overheat" or not, not wheather it would damage your engine.

I'm installing the unit on a high milage motor that has been making well over 200whp for the last 110,000 miles, so if it's going to cause something to fail I'll probably know about it, and yes I'll post it up, I don't sell the things, I only want to try it out, I absolutely wouldnt say anything good about it if it doesn't work out, why would I want someone else to have problems, like I said, I've got nothing vested in theese.

Oh to make full disclosure,
My Car:
'05 MCSC/JCW
Currently has 178,765 miles.
BVH installed @ 65,000 miles
Rings, Rod Bolts, Rod bearings all replaced @78,000 molrs along with the head neing rebuilt due to compression issues. (the problem was in the head but we had already pulled a piston when we found this out so decided to just do them all)
Cam, 1st Header, and injectors @ 136,000 miles
F/A software @ 168,000 miles
New Header @ 175,000 miles

So hear goes nothing.

 

How many more days until your S/C gets delivered? Do you have the old one off yet?

 

Appears the trolls are coming out of the woods - again.

Kevin

 

Your right this is about the supercharger. Not about the tuning software.

 

Do you know that a bad tune will knock the bearing out of a car right faster then anything else right?? Run to much timing where its making to much pressure in the cyl. because every degree of advance adds pressure into the cyl. and you will knock the bearings out. Run it with to much pre ignition-det-knock what ever you want to call it and you will knock the bearings out. Run it to rich wash down the cyls. There is a ton of way a tune can make you kill the bottom end of a motor other then throwing a rod or melting a piston. Maybe you shouldn't try to tune. I don't think you are getting the concepts yet.

Like I said though. Ill let this thread get back to the supercharger.

 

Yea, I agree, it was just my opinion in this case, with watching his thread and other discussions elsewhere, and yes I'm guilty of the sidetrack too, man I hate it when that happens.

Ok, S/C don't have the def. delivery date yet, supposed to be late next week, car comes apart and intake gets shipped off Mon.
