First, I appreciate all the input and the numbers. irregardless of the numbers, the curves are good, and the car runs great. that is the upside. the downside is, like mogs01gt, i know a lot of people who have way more power with similar and sometimes fewer mods. a friend of mine has around 310 rwhp on a 97 cobra, with all the same bolt on mods with the addition of MSD coil packs. just bolt ons. so adding a stroker, ported heads, and cams to that, only got me 10-20 hp?

Im making 310 at the wheels on my old stock short block on a 2v and my heads.
Here is a link to Mr. Bob Cosby's 99 cobra with just bolt ons. You should be WELL over these numbers. Im just using these as an example to what a cobra can put down. Im well aware that the 98 4v and the 99 4v are a little different. But I could have sworn the 98s had the B heads( a better head design). Im not too up to date on my 4v knowledge though. http://members.cox.net/bobcosby/cobra/images/t45sae.jpg |
i fully agree. something is just telling me that somethin is wrong. I am thinking too much port on the heads, or possibly a need for new injectors/fuel rails. what do y'all think?
