250? whoa.

A 185whp, 2200lb EG can pull LOW 13's, or 13.0 with a good driver.

So you're saying an extra 65whp gets you three tenths of a second at the drag strip? Doubt it.

Big midrange (i.e., cams, tuning, long tube primary header, etc), sticky slicks, and maybe 200-215 whp will do it, but this is all dependant on good drag strip conditions and a VERY GOOD driver.
