what is the best Cam Gear setting for 264/264 on a Vishnu Stage 1+ Car, how much HP/toqure will I get out of it with a set of Cams? on my Stage 1 I got 255whp with 91Oct, so what would I expect with a set of 264/264? oh and will it idle like stock?

 

Cam gears should set at -2,-2, which is recommened by Vishnu. With Camshafts and Gears you could pick up like 30 to 40 whp

 

how's the idling going to be like on 264/264?

 

Should be like stock, especially with Vishnu tuning, lol.

 

It will be slightly lumpy with those cam gear settings..I quite like the lumpy idle

 

This subject has been discussed pretty well, a search will find much more information. In summary though, -2 -2 or -3 -3 will give you more midrange and a slightly lopey idle with one degree difference helping bring power in earlier or later in the powerband, whatever your flavor. -4 -1 will sacrifice midrange and push the powerband back several hundred rpm but will give you higher peak horsepower with near stock idle due to the greater lobe separation. I guess you could call it driveable vs drag racing, respectively. I would choose the former for the better power in the midrange and the lumpy idle. Call me crazy but I just like the sound of a cammy exhaust burbling at idle.

Do a search and you'll find graphs showing the differences, I believe a member on here named TedB posted the results after dynoing on Andrews dyno. On your 91 pisstane I'd expect you'd make max power gains of close to 15hp and maybe a little bit more tq. Your idle will not be the same as stock, but the stock idle already sucks, so who cares?
