BiggFooT's Procharger F-1X Build - 1047 HP on SBE - Page 51 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

FooT, any ideas on what caused the belt to snap?

I may have experienced slippage this week for the first time. I was spooled up to about 6.8k in 3rd, then when I shifted to 4th, the power band went flat, but the rpms stayed around 6k.

Bump off Rev limiter? That's when they can break.

BiggFoot · 03-09-2018, 07:21 PM

I think the belt was already weak, but since I broke the line lock switch I tried to start the wheels spinning then hit the break with my left foot. Problem is working with two 13EEEEEE feet there isn't a lot of room down there to get it right. When I lifted the clutch I didn't give enough gas to keep the wheels spinning and those big 15's bit and the car just died in the burnout box. That might have done it but I don't know. I just know that after the tire shake quit the car wasn't pulling like it was before so I know the belt was already somewhat compromised.

I sent Rdunn a private message about this and fortunately for me he also has an F-1X cog drive set up. He said that he never had any belt issues until he went up to 30 psi. He suggests that we take a close look at the supercharger at WOT to see if it is flexing/moving. If so, then that could throw the belt and he said that the supercharger would need some additional bracing to keep it steady.

Items I am looking at for the next shop date:

1. New belt
2. Custom belt guard/cage
3. Check for supercharger movement under WOT
4. Discuss 2 step launch controller
5. Engine check over to make sure nothing else was damaged
6. Giving serious consideration to pulling the suction restrictor and just rolling the dice, cause when I go for the record I plan to be all in.

Thanks for the update, good luck with your future outing

2 steps etc can be very hard on things like that...more so with the cogs.

IMO, move to a 12 rib with a very good strong spring tensioner. Or if you need to persist with cogs...avoid 2 steps and hitting rev limiters in general

Or maybe try adding high sidewall idlers to keep better control of belt movement/walk, without the need for tension on the belt as it seems the cogs dont like too much tension at all.
Or maybe a spring tensioner on the slack side of the belt might help ?

BiggFoot · 03-14-2018, 03:52 PM

I don't plan to give up on the cog drive just yet. I really like the whine it gives and the shredded belt may have been a fluke. After we take a few more precautions and then it happens again . . . I will reconsider switching it out.

Hope the belt never comes off again but at least if it does it wont be tearing up my hood:

Looks great! I am happy for you, keep up the great work

Looking good brutha!

SSBUSDRVR · 03-27-2018, 10:37 PM

Great to see you got a fix!

BiggFoot · 03-28-2018, 05:52 AM

Was beginning to hear some whine and other disturbing noises from the stock transmission which has served me well over the years. It has been my experience that once a part gets weak then it is only a matter of time before it goes so I bit the bullet and will be replacing the stock tranny with RPM's Level VII TR6060 which includes cryogenic treating. I had to swallow hard on this one cause it is expensive, but my shop assures me it is worth the $$$.

Now if ATI would just make that Super Pulley/Sprag in something that wont rust and look like crap then I would be happy. Did you guys see the pics? Lovely to pop the hood to show someone your engine and that rusty sprag is there to greet you!

Moreair1 · 03-28-2018, 10:05 AM

Sorry to hear about the tranny, but at least now you shouldn't have to worry about that, very nice pics looks killer

Moreair1 · 03-28-2018, 10:07 AM

Just paint the front the belt will hide the rest

Silver14 · 03-28-2018, 10:08 AM

Would powdercoating the pulley work?
