I'm sure you could clear coat it, or get it anodized to protect it. I could get a quote on anodizing if people want that option.

So any documented mileage gains by anyone with this pulley? Or is any potential mileage benefit offset by everyone revving their engine more? :)

The automatic trans discourages me from revving the engine. No heel and toe shifting here. :-(
I track mileage but don't drive much so I can't report anything significant. I think I have put 2 tanks through now with the pulley. I switched to Mobil 1 I think one tank before that so my numbers will be skewed. I would guess that the pulley would have an unmeasurable effect on MPG based on how I normally drive but I am trying to do everything possible (The one exception being I added 100# of sound deadening.) Really I think the pulley improved "drivability" without adversely affecting mpg. Shifts seem a bit smoother. Last tank was 41+ mpg. Went 412 miles on the tank. Screwed up my records forever by not filling up all the way because I had to fill up near an airport $$$. Some day I will have to find a bone stock 2010 Yaris to compare how it feels. I have made so many small changes and don't know what a normal Yaris is like any more. I drove a rental Versa last week. Whooo, glad I have the Yaris. |

So, I've had the light weight crank pulley on for just about 3 months and I'd say the verdict's in for fuel economy...
Long story short, since I'm now back in school and money's a little tighter, I've been trying to find ways to cut back on expenses. Starting around April of last year, I've been paying attention to how fast I drive, when I shift, how much I coast, etc. Very mild hypermiling. This netted me about an extra 3.5 mpg. Installed the MI LW crank pulley on the 30th of July. Wasted the left over tank of gas enjoying the little power boost from freeing the engine from it's parasitic stock pulley... Ended up pulling an extra 2 mpg without really changing my driving style at all. Pretty sweet, if I do say so myself! dotted2.png

I have noticed that even with my aggressive driving habits I can get high 30's and if I drive on roads that are less than 60 mph and drive cautiously I can get around 43 mpg, granted I have some parts added to it other than the pulley, but yes I agree, free power with out increasing fuel consumption seems to add up to better fuel millage. but that is a pretty fancy graph there, and i assume that the dotted lines are the average for that section.

Thanks! I just eyeballed it with the graph, but that's about the average for each bit that I was talking about: (a) pre-paying attention, (b) paying attention, and (c) after the pulley, but still paying attention.

How long have you guys had those pulley installed? I really want to get one but I'm afraid that it will do damage. All the suppliers keep saying its fine but they just want to make money i wonder if u guys have had any problems with the lightweight crank pulley. I have intake header and exhaust, this will complete the package. I need positive feedback and conformation that it will not damage my engine!

I installed mine 4-27-13, put about 50miles on it and no damage yet. On a serious note though, I read a lot of threads and websites before I bought the pulley. It came across to me the only problems people had were those not installing it correctly.
Examples: 1. The pulley wobbles? It was not aligned properly. 2. The pulley came off? It was not put on at 95 ft/lb. 3. The belt now makes noise? The belt was not adjusted properly, either too tight or too lose. There were no reports of stress failures or at least nothing I found. Granted everyone wants to make money, but no one is going to suggest something that will damage the car or they would not be in business long. When I talked to Geoff at MicroImage he said the header, exhaust, air intake and pulley will net you around 15 to 20 horsepower total for the 1.5L Yaris. Which for around 1000 dollars you get almost 20 percent increase in power. |

The only reported damage to a yaris was a race model, that went above the 8k RPM mark. The stock rev limiter won't let you get that high. I've had my pulley for close to 90k miles with ZERO issues, except a more fun to drive car.

Let's make a distinction between the Micro Image pulley and the now discontinued NST pulley. I prefer to address concerns about ours, since it's the one that is available now.
Our first production run had thinner edges on the ribs, which on Jason's race car caused a problem over 8000 rpm. This caused belt wear issues on that car. Stock limiter is 6250. Our second run included a pass with a special machining tool to square off the edges, closer to factory shape. This is the red/black version we sell now. I would trust either pulley on a street or mild race car. We do have a commitment to providing quality parts and improving the parts we make when we see a need for that. Happy to answer any questions or concerns, always.

+1 with Garms above statement! I totally trust the products that he makes. I've had my pulley installed for about a month now and i'm 100% happy with the results and performance of the microimage pulley! BTW i have the black pulley
