Cogged or V belt. Which do you use? Plusses and minuses?

Cogged
V belt would screech once in a while when you go wide open and cause a distraction.
I have very limited adjustability on my dragster.

Cogg. Belt only needs to be snug, not overly tight never slipping. This is 2-1, 150 amp alternator with 2 ga wire and always 14v+. Best belt upgrade I made in 2024. I never charge battery at the track…..NEVER!!

I'll be d*mned. When I pictured a cogged belt, I didn't even consider a cogged pulley . I've run a cogged belt with stock pulleys and didn't notice any difference. Guess I know why, now. Take care. Tom Worthington

V belt, same one for 20 years spare is probably dry rotted from sitting.

V belt on both cars.

Cogged, Rounded Tooth Design Belts/Pulleys, and Jones Racing Products alternators, pulleys, and drive mandrels. He's got the nicest stuff out there, you won't be disappointed.
