Does any 2nd Gen owner besides me have this setup?



I am having problems with power output and would like to converse with someone who also has this kit.



Thanx

keep in mind a N/A engine isnt the most powerfull thing

to begin with, let alone a carbed one

I am running 6 PSI with a Holley Blue fuel pump. It is like brand new. Only about 8000 miles on it.



It is the RB setup with the modified 600 CFM Holley.



I have no idea what size jets are in it.

Make sure the secondaries are working. I read (I think on the evil forum) that someont had a problem with this.

You can unhook the secondary linkage and see if it loses power, or put a screw in the linkage to force the secondaries to open.

on stock ports, even carb'd its hard to get much power from NA... on a heavy port, carb would probably be very good power if tuned right

I'm talking about 13b six port... I've never seen any dynos where a carb'd six port with stock ports put out much but I haven't seen many to begin with.
