IMO every SC mini should have it installed especially if your going to keep the stock IC. The benefits of injecting w/m are loads:

- keep IAT below amb. temp.
- Running meth is like running race fuel (but cheaper)
- Safety factor by stopping pre-det on the engine. SO you can floor your car and have the peace of mind that its safe.
- POWER!!! Untuned for meth approx 8-12whp..tuned for meth 20-30whp...

One of the best mods that ive done.

 

Who makes an 11.45% reduction pulley? All I've seen for aftermarket is 15, 17, & 19%.

 

i know the jcw has a reduction pulley on it.. could that be the 11.45? i thought it was more like a 13% though...

 

Ya, I believe the JCW is 13%. I would imagine that an 11.45% pulley would have to be custom made.

 

I believe that the "11.45% reduction pulley" referred to by "k-huevo" is the factory JCW pulley.

Hope this helps...

 

That's what i thought, but how does one upgrade to this as suggested by k-huevo with out getting the JCW package?

 

Perhaps you can PM "k-huevo" or "partsman" as they should know.

Hope this helps...

 

While it's kind of on topic, when installing any of the aftermarket reduction pulley's is it possible to remove them WITHOUT the pulley tool?

I know BMW's always have special tools for almost every job thats done, but theres usually tricks/tips to going about without it.

 

Forge use to do an 11.45% pulley don't know if they still do.
Kavs motorsports can supply a JCW 58mm pulley http://www.kavsmotorsport.com/conten...15/29/lang,en/

 

For the OP, keep in mind that if you tune your car so that it NEEDS meth, if you run out you are going to be in a bit of a tight situation. Meth (unless it is tuned for) isnt going to be making a lot of extra power. Rather it does a good job of maintaining power by keeping your IAT's down when running harder. In other words, on a hot day your 15th pull should feel like your first. One member, Blimey Cabrio, has a very extensive thread on the benifits of runnig meth without tuning for it. Search "Devil's Own" (name of the meth system) and the should take you to the thread.


If you want to remove a pulley without a puller an angle grinder can do the job. In all serousness, I am pretty sure Alta can loan you a puller if you buy a pulley from them. The reason you basically need the puller is because the stock pulley is a friction fit, no way to get it off without a puller or heating it a bunch which risks damaging the SC.

 

Well thats true if your car was tuned aggressively for meth...If the car was tuned moderately for it, then it'll be ok.

Plus, my mini isnt tuned for meth and im seeing 15bhp (not whp) more with meth...but mind you, where im from the amb. temp is an avg 33 deg C.

 

Umm no...If you are tuned for meth you don't want to run out, end of story.

 

Really? I tot if it were lightly tuned for meth it'll be ok...

Ok, please explain me this...if your tuned for meth and your driving it lightly meaning (change up at 4-5k rpm) will it hurt the motor?

 

Gonna do a bit of knowledge dump and see what comes out. This is MY understanding of it, as in, it might not be totally correct.

Meth serves two purposes basically. Raise the octane and cool the intake charge. By doing that you are lowering the "chances" of pre-detonation. If you take that away, your ecu is going to have to compensate for that by changing timing or fuel mapping (richen the mix). The question then becomes "can my ecu make that change?". That would be a question for the tuner.

On the subject of being alright running under light load. That depends on how aggressively tuned for meth it was (how meth dependent it is). Eventually this boils down to how detonation resistant you engine was at a given load and how much the methanol tune would have changed the if it were running on its own without meth.

Hence it can be anywhere from sort of a problem to a really, really big deal to run out of meth if your car relies on it in some fashion.

 

Naz you should read up on the basics of meth tuning

If you are going to tune for meth why do it half-way, it doesn't make sense? Why go to all the trouble for a half **** tune that is not going to give you much more hp?

Basically when tuning for meth you can lean out the fuel mix and advance the timing to make more hp. If the meth stops....you will be running way too lean with too much timing, not good for the engine.

 

Thats because you are running a stock map on a modified car.

When you get your Mynes remote tune that will decrease....

 

Hmmmm...

thats great info D-Man....always there too help a fellow Mini modder...

Thankfully, Mynes can tune for meth...But it gives me the jitters thinking that if the meth runs out in the middle of the highway....GULP!

 

Yes, you'll just need to drive around with your laptop in your car .

Longboard

 

What makes you want 200+ hp as is?
Have you driven a car with that?
Give us a shoutout im sure theres someone in your area thats willing to take you for a ride/let you drive their car.
And then i feel like your better prepared to get to your goal. and have a realistic version of what you want.
Not that what you want is unrealistic.
It just may be not ideal.
PS the miltek catback is pretty quiet but still sounds very nice.
