I suspect there is a bit more to gain. Getting one of these cars below 10 seconds would require an interooler though. They are running pretty much at the limit stock. I wonder if I adjusted my IP timing to 14ATDC if I would or could gain anything?
Probably not worth it, one could go nuts warming over a 603 and what is their to gain a 1/4 of a second maybe?
Bet with an intercooler I could knock 2 seconds off that time...
