JBA Shorty Header Dyno Results

^Well thats like an accepted theory. Basically LTs have shown a VERY low gain on blown 2Vs...and shorty gains have been about the same it seems.
4V have MUCH more flow, and will benifit much more from a nice set of headers. But in the end, LTs> shortys in any application IF BOTH types of headers are designed correctly for that application.

Yup. Most '03 Cobra's come with them stock.

As for those terrific gains keep in mind the graph represents the installed headers PLUS a tweeked tune to take advantage of them.

U.M.

why would it be most and not all 03's

he was just kidding around. all 03's came with a blower stock.

hotmustang, are you saying that if a guy has a blower on his 2 valve then adds l/t he wont gain much?

i didnt think that i just thought both the l/t and the jba shortys gained the same with blowers. however i thought the gain was ok.

btw guys i only heard this about the jba shortys, that they were almost as good as l/t on blown app. i did not hear this about all shortys

Thanks for the information everyone. Looks like it may do some good, especially for forced induction applications.
