ev or csu hat fro blowthrough

[nos81bu]

opinions on which one is better..i like the way the extreme velocity looks..but is it better than the csu or the same?

[SNYPER]

I run the EV hat...from what I have researched the EV hat flows better than the CSU.

I believe Steve Morris did a back to back test with the CSU and EV hats. On a 1600+ HP BBC, the CSU hat was worth 70 HP over the EV hat.
Here is a discussion about it http://www.turbomustangs.com/smf/index.php?topic=33931.0

I run a CSU hat and have never had any problems.

[TheMyth]

Not trying to start anything because I am curious myself, but then why does Steve Morris run a EV on his wagon with that dominator?? Does CSU not make a dominator hat or something??

EV has the only dominator hat I've seen. CSU doesn't have one.

[TheMyth]

I was told that when running the EV hat, that if you are running over 800hp they highly recommend their 1" spacer, and it must be mounted at 90 degrees to the carb to perform properly.
