what car and what does it weigh? What are your engine specs?

I run a modman with a pair of 600s on a 499 with SRs and a small indy flat tappet cam at 12.5 to 1 comp. My car weighs 3550 and I ran a best of 9.99 with mine in NSS trim. Not enough room to work in bad weather. I backed mine up to B due to that.
