wtf? did u edit your post? i swear this is not what i read?

i was talking about the runners btw, not ports

we are on the same page, sorry if i misunderstood

 

Thanks for the pics kahren/ito!





I'm probably prying now, but I am also curious about intake manifold setup.. Throttle design.. etc...

 

na... non-edited. LOL

we all good though.



but now that i think about it, i remember the primary ports (port oriface) actually being smaller... i'll double check it as soon as i can tear that motor down. might as well do the comparison pics and post up just so people can have the reference anyway.

 

i forgot to take a pic of the overlay a stock fd port over the 13b-re one to show the exact diffrence of the port timing and shape.





like this

 

I really like the N/A set up I have. music to my ears.. that partial p-port gives it the extra melody I was looking for..

 

i'll try to do that.

 

Yah, I bet you do. Your makin good power. I cant wait to see what you get with both stages of Nos.

 

alrighty..



i didn't get the exact right angle on the pics, but it should be enough to give everyone who hasn't seen an idea of the differences and similarities between the cosmo and rew motors.



secondaries appear to be almost identical.



primaries are not only shaped differently, but the cosmo primaries open later for less overlap--good for low end.[attachment=34690:attachment][attachment=34691:attachment]



the cosmo is getting ported today, so if anyone wants any other pics, you've an hour or so to request them...

 

wow. this is almost scary. i haven't been on this forum in ages and i had this same idea last week. i'm really curious as to how many people run this setup (RE side housings with Renesis rotors) or something similar in a normally aspirated form.



i really don't think low end losses should be THAT bad. midrange and top end should be phenomenal though.
