Pro 7 Questions

I am in the process of building a Pro 7 car and had several questions.

1. What wheels are you guys running for Pro7? I know they must be stock size and offset, and also the total weight limit. Is there a wheel choice combined with the spec tire which weighs around the limit.

2. What timing advance are you running?

3. Without the double pulley available, are you noticing any belt slippage?

I would love to see tons of Pro 7 pictures. Really interested in interior, routing of air source for brake ducts etc.

How many guys on the forum are running Pro 7?

Hey, although I don't race Pro7 (I'm building a budged GT-3 type race car for Touring Car Club), I do hang out with a lot of the Pro7 guys.

1. Just use the stock rims. They're cheap and pleantiful. I've never seen anyone else use a non-stock wheel in Pro7. They can be polished and painted if you want a custom look.

2. 22 leading 14 trailing total timing. Measured at 4000rpm. Always have a 8 degree split between the two.

3. You will notice belt slippage above 8000rpms or so. But your peak hp and shift point is around 7500rpm.

Good luck!

Pro7 reply

1. Stock aluminum 13" wheel, cheap and easy to get.

2. Running the pulley marks on the Mazda Comp. pulley at @4000RPM.

3. Belt slipage, n/a because not running a clutch fan, small electric fan if needed. Change belt ever few months, $4.50 cheap insurance.
