Are they both the same size and the where did you obtain the manifold? Thanks! The idea sounds cool, fast spool up, reliability and lots of power!

 

the were both the same size...but in a fit of craziness i sent them to the builder and had him put in a larger secondary than i had. the idea was that with the bb and the primary that is about 25 percent larger than stock that i would increase both spooltime and output way down low. i wanted a larger secondary to get the gains up top and take advantage of the streetport.

the manifold is stock. i checked into other manifold ideas...including boring this one out...but it was not worth the time...it would have to be a complete custom job to make it worth the effort with the manifold.

i sent them my manifold full of cracks and got a new manifold in return...perfect.

the car is at xs right now...spent all day on the dyno...i dont know if im going to get the numbers i want or not at this point..i thought it was fuel issues...but it turns out that Im having some heat issues...intake temps are too high. they are going to do the final runs tonight and i should have the sheets first thing tomorrow afternoon.

So the smaller one is your primary and the larger your secondary?

 

yes...but the smaller one is stil larger than stock

 

oh, nice!
On the stock, is the primary larger than the secondary?

 

A stock FD was 2 Hitachi twins that are the same size - on the Cosmo, the secondary is a little larger than the primary

 

Are you running them in sequential?

oh, thanks a lot!

 

yes

 

Any pics... I wanna see!
