Today, I am going to try to eliminate a failure point on the Mini: the crank pulley. To give the car a more refined experience, BMW added a two piece crank pulley to the Tritec when they adapted it to the Mini; the rubber holding the two pieces together eventually fails making the car undriveable until replaced. To prevent this, I am going to install a one piece aluminum crank pulley from Alta; this pulley is much lighter and slightly larger in diameter to spin the supercharger faster (it won't make a huge difference). Most people are concerned because they think the crank pulley is an engine damper; while it will help with some secondary harmonics, the two piece flywheel will accomplish the same function. Plus, the Tritec is used in other cars with a single piece crank pulley without issue. You could run a fluid damper, but for my purposes, the extra investment isn't worth it.

Do you need to change the crank seal when replacing pulley? I would greatly appreciate your expertise. Aloha & BeSafe from the Bigisland of Hawaii

You just gonna blow all the bearings in you engine instead of spending 150$ more to get can a gel or stock damper that absorbs the knocking ... Bravo

What size are the Alta pulley threads?? They seem much smaller than on other pulleys.

Is the m10 bolt any thread or x1.75?

@350Z247 2 жыл бұрын

The M10 is just to have something to press against. It could be just a 10mm rod. Nothing special as long as it's somewhat strong.

Did you need to tune it because of the 2%

@350Z247 2 жыл бұрын

Nope, it shouldn't make a big enough change that the computer can't handle it.

@nicolaisadowski8787 3 жыл бұрын

hey man, did you use something like locktide to glue the bolt in? did you have any issues with the bolt like its coming out from engine vibration and spinning because of the rubber delete? i heard about that..

@350Z247 3 жыл бұрын

The replacement crank bolt comes with Loctite on it. I haven't had mine come loose, but it wouldn't hurt to check it when you're working near it

@Noah Passey yup, I've done it several times without it, but just buy the $30 tool. It's worth it.

@Noah Passey it won't be a big difference, but in my mind, every little thing adds up. So, my car is very mildly modified, but the entire experience is much better.

@Noah Passey yeah, about 5whp. Maybe a little less. I didn't notice any sound changes. It's a small change, but a cheap and easy one. My main motivation was to remove the possibility of the stock pulley splitting in two.

@Noah Passey It's a roots blower; so, the pickup is everywhere. It's a solid gain for $100. The bigger intercooler is a waste unless you're pushing big power on track. The "One Ball" mod is purely for sound and offers almost no performance benefit aside from the weight savings. Even then, it's a small amount of weight in an area you aren't trying to lose it from.
