Ok I had my car dynoed in May and it dynoed at 310rwhp, and I'm upgrading a few things and just wanted to see what you guys think the gains will be , roughly ?

I'm changing :

BBK cai to the JLT cai

24lb injectors to 30lb injectors

75mm MAF to 80mm MAF

Edelbrock RPM upper to edelbrock RPM II upper

BBK equal length headers to BBK longtube headers

 

Same dyno? If so, maybe 10-20rwhp.

If its a different dyno then it could be higher or lower than before.

 

Yea same shop same dyno!

 

dyno #'s really differ from dyno to dyno and day to day like stated. the biggest gains would be from the long tubes over the shorties and smaller gain in the intake over the current one, since you have a decent flowing aftermarket intake and going to another one with more flow capabilities. think of it like going from 3.08s to 4.10s vs 3.55s to 3.73s. one you notice alot the other not so much.

you have a modded motor that is pushing about what a really good h/c/i n/a would make rwhp wise, you are getting to it's limits. like Knight stated you will net some small gains but really the next move is boost ( like the low boost set up you want to do or aftermarket block and big boost/turbo) or cubes ie 347 or 351 and stroking that to like a 408 or something along those lines.

 

Well put together , yea I found a Vortech v-3 Si-trim 6psi supercharger or $2,100 , I think that may be my best bet
