    Ok I cant find the article and Web motor sports page is not what it use to be:Nailbiting: But I don't think it addressed Meth anyway. Sorry. I know once I let someone talk me into not building an engine the way I wanted and regretted it. I would just make sure 19% isn't going to over spin anything.
    But hay look at the up side. If it goes south on you just remove the whole thing and send it to Jan and tell him make the baddest R53 motor he can. Its just money.:D

    Yes I reached out to Jan, Detroit Tuned and Way over on the BBB forum. I am only to do some searching here, the MA search function is much better than over there.

    From different web posts it appears the MINI is designed to rotate the supercharger at 2.06 times the engine speed, 6800 x 2.06 = 14,008. The 14,000 value is what all of the Eaton data I can find reflects, anything more than 14.000 is not there. I have read posts where somebody did some testing at 15,100.

    First if Dave.0's ( I like to prod a Tiger) engine is redlined at 8k and if he has his foot hard on the peddle his supercharger with a stock pulley is turning 8000 x 2.06 = 16,480. So now the question come for most of us that were school prior to computers and in Vetsvette time prior to TV, does a 15% smaller pulley equate to 15% to be added to the 2.06 factor quoted earlier???? If it does than you could also apply the same reason to the JCW pulley that is around 11.8% smaller. This would mean the JCW supercharger is spinning at 6800 x 2.3 = 15,649,

    I am so glad I am doing this here as over on the BBB forum you get you ass slapped very hard for going of topic and this is a brake thread.

    I heard the Admin and one Mod over there are real buttheads . . . . . . .

    Yes they are BIG BUTTHEADS!!!!! but this begs the question can you hijack your own thread? Do you know its your thread? or are you just old and forgetful like @vetsvette? these are deep questions.:D

    Yes the 15% smaller than stock. I will let you do the math. I have been told its better to be quiet then remove all doubt. So I will be quiet

    OK, found some different data. Appears the stock crank is 140 mm and the stock sc pulley is 65.5 mm. The JCW pulley is 58 mm (about 11.5%), the 15% pulley is 55,7 mm, and the 17% pulley is 54,4 mm. Last the ATI 2% overdrive crank pulley would be 142,8 mm. On redlines, it appears the start is 6750 with fuel cut out at 7000. The problem is that if you use standard pulley ratios the stock and the JCW is reflected below but everything that Eaton has says 10 PSI at 14,000 RPM: 1.) Stock = 140/65,5 = 2.14 x 7000 = 14,980, 2.) JCW = 140/58 = 2.42 x 7000 = 16,940.

    There may be some factors involved so using the 2.06 I have in a post above we have:

    1.) Stock = 2.06 x 7000 RPM = 14,420 SC RPM
    2.) JCW = 2.06 x 1.115 x 7000 = 16,078 SC RPM
    3.) 15% = 2.06 x 1.15 x 7000 = 16,583 SC RPM
    4.) 17% = 2.06 x 1.17 x 7000 = 16,871 SC RPM
    5.) 19% = 2.06 x 1.19 x 7000 = 17,159 SC RPM

    If these values are somewhat correct than the JCW SC RPM value is well above the 14,000 value that Eaton publishes for the M45. I have seen posts on other types of forums that talk about porting the SC in an effort to aid in lifespan when pushing higher RPM's. The question is where is the magic redline for the supercharger and does anybody have pump curves for the water pump so it can be determined where cavitation commences.

    Truly you have a dizzying intellect!:D

    You could go with an electric water pump and solve the water pump problem. As for the rest I do not know. Maybe the question is 288RPM worth the risk?

    There was this other guy that got out of a great looking red Gen1. Had a Pennsylvania vanity plate, something to do with a woman. You know him around these parts?

    Now back to the jacked brake thread, I just read something from years back that the M45 max is 16,000. It also appears that my 2.14 pulley ratio is correct. That means the JCW is pushing well over the 16,000 value.

    So how many 17% pulley folks we have here and many miles on the car after changing to it?

    I am one. Over a 100k I believe. No problems with the 17%. That being said, the delta on the heat is big during the summer months. Definitely Meth would help or a better intercooler. I hear window wishing fluid is the best to use.:D

    Gee you guys here are sooooooo helpful. I am going to run down to Walmart and buy me a bunch of that blue stuff. The more expensive winter stuff is not on the shelves yet.

    The money I am going to save . . . . . .

    I think I had around 100 deg F heat rise. Its been a long time ago when I logged it so I cant really remember. I believe @Dave.0 said the Meth brings him back to ambient. He has a 17% now maybe he can tell you what it is with meth.
    That picture cant be Dave, I know because his middle finger would be a little higher then the rest.

    17% with Meth is fine on my car because I do not track it and only drive it maybe once a week if I am lucky.

    My Aquamist Meth kits is controlled by my ViPEC ECU and I run the 2nd largest jet they make which is a 1.00. I also do not run any type of 50/50 boost juice, I only run VP M-1 methanol that I buy in 5 gallon VP sealed drums.

    The last time JAN and I logged my car the Metth kit it brought the ambient temps 10-20 degrees lower than ambient temp and I am also tuned for Meth. We did very hard pulls and did data logging on hellbender on a very hot day 2 years ago.

    Do you have an electric waterpump?

    Back to pulleys, running just numbers if the Redline Cutout was lowered to 6500, then a 19% pulley, that would provide more low end torque, would be spinning the supercharger at around 16,500 that is actually lower than the JCW pulley does. I could be way off base but what I am thinking is the heat is caused by the boost/pressure hitting the valves, backing up and causing the sc to work harder. So how does a cam and a high flow exhaust help mitigate the issue as they both let the air flow better through the system?

    No I do not have an electric WP yet but I will when I go to a TVS and get rid of the M45 heat pump.

    The heat come from the M45 EATON a.k.a ‘Heat-On” spinning way out of its running range. It is a old design and is not very efficient at all. That’s why JAN and other have been trying for years to come up with a bolt on replacement for the old tech “HEAT-ON” M45.

    HARROP is Australia has a complete kit available now to replace the old school OEM M45 SC and upgrade to the new Eaton TVS 900 SC.

    http://www.tvsmini.com/

    JAN sell the kit in the USA
    HARROP TVS900 DIRECT BOLT ON KIT $3,325.00
