What happened here?

Post  460bronco on August 29th 2015, 10:05 pm






This was a 1" quickfuel tapered 4-hole spacer.  When I pulled the carb I found this.  Would having a nitrous plate under this spacer have anything to do with it?  Had them on in the sequence: carb- spacer- single stage plate- intake.....

First impression is that the part was just machined a little thin in the connecting areas and the heat just got to it.

The plastic ones should be marked as being for "drag only" use because they can't take heat for extended periods.

Sure it's plastic and it got hot and melted but I am intrigued by the "twist". Why would that happen?

It looks to me like it got twisted because it was catching on a throttle blade on the primary and the secondary side.

I have a feeling the thin area saw temperature fluctuations that were greater than the area in the center that had more bulk. This led to increased expansion and contraction compared to that part and thus the twisting. It did also definitely contact the throttle blades because there were nice beveled places where the blades had worn the twisted portion. Lesson learned.... No plastic spacer of this design with any street use...

It now just has an open spacer on...

Will the Phenolic tapered spacer hold up to street use?

Phenolic will be fine.

Yeah, my I-Phone 6 is great for photos and slo-mo-vids, etc....but it'll be my last Apple product. After owning I-Phone 3, 4, 5 and 6, I've learned that customer support is non-existant.

It's a repackaged HVH SuperSucker spacer.

Like has been said, the Jomar Power Cone phenolic unit would be a better bet.
