Raceseng | Billet Aluminum Engine Pulleys
 

In the process of developing and testing our very own engine pulleys.

I like the design nice machining.

Are you testing them with a higher rev limit?

Looking good what's the weight?

Just an FYI

I had a pulley with a spoked design on my car for a few months. After a while I realized it was collecting dirt in the apex of the spokes, which seemed to unbalance the engine. I could feel it running rougher and was getting a burnt oil smell after high rpm use. I went back to stock and everything is back to normal. The installation was done correctly, there was no wobble, the key and o-ring were seated properly.

I don't know if my experience was a singular event, I haven't heard of anyone else having this issue.

Yes, I will be testing them to 8,100

Thanks Markitect! We have a couple sets prototyped and our cars for testing. Simmons is using them on his AutoX car.

Calum - That is really odd because you would think that the dirt would collect equally in between the spokes. I have never heard of this happening. The only thing I can think of is that the pulley might have been out of balance from the get go.

Kartboy's is $95 USD and closed face.

I checked and re-checked but it was running true. :iono: It seemed odd to me to which is why I didn't think about the pulley right off. I'm still not 100% convinced because of how odd it is, but the dirt was there and the problem is gone.

I haven't heard of anyone else, on any model of car, having this issue so I'm 99.99% sure yours will be fine aswell. I only mentioned it because you seem to still be in an R&D phase and this might be something you'd like to test before going to market. I certainly wont be criticizing if you find it's not a worry.

While i do love having our parts plugged, I do not condone posting on other companies Threads unless we are asked a direct question.

As a CNC machinist i have to say that pulley looks pretty kickass. I've always wondered if a design like that would whistle. Only one way to find out.
Keep up the good work.

Any idea on the weight of these pulleys?

Looks sick, in for weight as well
