i've been toying with the idea of an intake manifold or porting mine. this lead me to looking at the LSXr. it looks nice and the gains are fair enough, but i was not interested in adding the billet fuel rails and the associated plumbing that goes with it. i know, not really difficult, but in my opinion it overpowers the engine bay.
they have the spacers to allow me to run the stock fuel rail, but i'm concerned about the effeciency of the injectors when they are shooting through a tube rather than righ into the airstream. i'm sure it is good, but i could not find anyone who had done a before/after with the spacers to see the effect on overall performance.......
so i was looking at the "crawford" mod for the stock intake.

it's been around for a few years, but new to me. i decided i'll give it a go. Ryan was real helpful and put up with quite a few questions. i ended up getting an UDP at the same time.
i decided i have the time to do some science. so i'll do a couple of pulls on a dyno and then swap the pulley, do a couple of more pulls, swap the manifold do some more pulls and see what i get out of them both. the car shop has been helpful and we'll get to it near the end of April. i hope to post some gains.
