Got $10k to spend?
-5.0 stroker high compression forged shortblock
-Max effort NA cams
That basic combo will yield 375-400rwhp on a 2V. Completely and TOTALLY not worth it when you can get better results with a supercharger on the stock motor and retain the stock street manners and gas mileage of a factory 2V.
If you are talking about with just bolt ons and cams, its an achievement to hit 300rwhp in that instance. Cammed 2Vs normally run in the 285-300rwhp range and do mid-low 12s at the 1/4 setup properly. There are some that break into the 11s but they are often NPI bottom end cars with a lot of weight reduction and a really good driver or an auto swap or both.
2000 Mustang GT Steeda build #48. Bolt ons, suspension, Novi 2000.
Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
