A question for those with MI pulley - Toyota Yaris Forums

Captain Slow · 08-21-2012, 01:03 PM

Can you describe the difference? I'd imagine the motor revs a little faster (which must be nice when trying to take off from a stop). Anything else you noticed?

malibuguy · 08-21-2012, 01:13 PM

overall just better response. almost makes the throttle feel non electric

i'm not sure if i an really tell you the difference seeing as how i installed a lot of other parts at the same time. in general improved response and seems to rev easier and quicker.

That's a very good description there.

Definitely gives you better responsiveness / a better throttle feel.
I've also picked up a few MPGs once I slowed back down after I installed it.

Hey, that's a good review.

I'll be adding some fuel economy info to that review within the next week!

One way to notice the difference is to drive up a hill that you could previously barely hold in a particular gear, or one that you slowly lost speed on in that gear.

The ninja pulley will make itself known at that time. B)

Captain Slow · 08-21-2012, 03:54 PM

no hills here, lol

cali yaris · 08-21-2012, 04:03 PM

you're right, that looks REALLY FLAT.

Black_griffin6 · 08-21-2012, 04:30 PM

I haven't noticed a big different to be honest, I think it pulls a bit more stronger now.
I've got the MI crank pulley and the NST Alternator and WP pulley too.
It does rev a little bit faster, but like I said, I don't notice a huge difference. Maybe i'll have to try the hill trick like Garm mentioned.

I have noticed however, whenever the engine gets hot my drive belt squeaks now. I've already spent 150 bucks on a new drive belt and the noise went away for a little bit, now it's back again.
I dunno if the pulley's are ruining my belt or what's going on, but if I have to spend another 150 on another belt i'm taking them off and probably selling them.

Captain Slow · 08-21-2012, 04:35 PM

that sucks. anyone else have this problem?

Who charged you $130 to install a $20 belt?

I have the NST 10%UD pulley. I have always had a squeal on cold startup with this pulley. Can't get rid of it with belt replacement or adjusting tension. Can't say as the pulley is destroying the belt tho. Wife did once gun it out of the driveway cold with the A/C on. Belt squealed so bad I could smell the rubber wafting up the driveway. That wasn't good.

As far as improving F/E, haven't noticed a lick of difference. Engine does spin up quicker, and this is with A/T.

Mine started squealing about a week after I installed it. Replaced the belt after realizing that there'd be no way for me to get rid of it without replacing the belt. $18 and 10 minutes later and I've been squeak-free!

Who else would charge you a lot of money for something really cheap?
The stealership.

I took it in to the dealership because I was really concerned about the squeaking. I was worried I ruined something on the belt because it never made this sound before, and not matter what tension I put on the belt it would squeak.

I took it in and told them I had a squeak in my drive belt whenever the engine gets hot, they said they would look at it.
I wait a bit, and they come back and say "So you need a new drive belt. That's going to cost 150 bucks." I said yes because if I did mess it up I figured they could do it right.
I feel kinda cheated out of 150 bucks because my drive belt was probably fine.

If the squeak is normal with a light pulley then that's okay. I was just concerned about it since my car has never squeaked or rattled or anything.
It's not really noticeable anyway.

I hope to combo the pulley kit with a lightweight flywheel to really make it rev more freely.

Golddeenoh · 08-22-2012, 12:23 AM

I had a little bit of squeal, but again I did a lot of mods at once, replaced the belt and readjusted it after a few days and no more squeal. I ironically i didn't have any squeal problems until dad helped me attempt to put on my alt pulley (still not on, lol).

SAV912 · 08-22-2012, 12:50 PM

I've noticed with mine that it is a lot smoother in gear at low revs. Like I've freed up a lot of low end torque. Taking corners in the subdivision that previously required dropping down to second, can now be taken in third with no grumbling from the engine like it's about to stall. It's also a lot smoother up the gears in normal city driving.

I've revved it out to the limiter a few times and it gets there a little quicker but I'm not feeling like it's hugely faster, or that this was the biggest benefit to this modification. Keep in mind though, that the OEM pulley weighs about three pounds and the MI weighs less than one, so you're wasting a third of the power you were with the new pulley.

This squeaky thing concerns me... I don't want to worry about my Yaris sounding any other way than what it does now... =/

Just make sure you have the correct amount of tension on the belt.

If you don't get it right, well you can buy a new belt and then make sure you have the correct amount of tension on the belt!
