Fuck these things they just crack and fall off then your tune goes to shit

There are so many reasons I don't like to use the o-ring style soft mounts, but nobody seems to listen when I recommend the OEM style vulcanized rubber mounts. Yeah, they aren't super easy to source, but they last forever and do the job well.

I use them whenever I can, like on these setups.

Ran into an issue.. was popping back through the intake.. sprayed some brake parts cleaner around intake and its leaking at the head .. took intake off and it's not exactly flat .. against a piece if glass it has just a hair bit of wobble ... so little bit of a set back

Yeah, I could hear that popping in your video. Sounded like carbs out of balance...

 

Note that you will have to slot the manifold to fit the roadster isolators. You can see in the pics that the studs aren't the same spacing on both sides of the isolator. Nissan used to sell non-offset isolators, but they are no longer available.

 

I cut the isolators in a lathe to soften them up. Like this -

Yah when i put the little tool on to see where they were, they were way out .. but i followed the instructions http://www.redlineweber.com/html/Tech/dcoe_adjustment_layout_typical_i.htm

 

and it was still carrying on .. sprayed the brake parts cleaner and idle went up on a few runners.. so my buddy is taking it to his shop today to True it up and get it flat

Webers tend to like 3.5lbs.... I had 6 to 7 on mine and I caused an over rich condition....... I know some dont like them but Holley does make a nice lower preassure regulator.... I can find the part number if you want....

So shoot for 4 then... its more important that they are all equal.....

I know when I balanced my single I brought the lower up to the higher....

You might find you cant go any lower with 1, just balance accordingly.....

I have a good pressure regulator, its an aeromotive 13301.. super easy to use and adjust .. 

 

Didnt mess with it to much this weekend though because i cant get the damn thing to seal and its leaking air somewhere.. Almost looks like my hardware is in at an angle..

flange and carbs dont seem like they match? i either need to get different hardware or slot the holes a little to make it work

 

Gonna pull it off tonight and tinker with it

Are you talking about the rubber soft mounts? Did you get them already?

 

Yes, the two studs on the back of each isolator have a wider bolt pattern. You will need to slot the manifold. Do you know anyone with a mill? Super easy to do on a mill.

 Its the thackery washers that redline gives you with a cannon intake that are poop. Those rubber insulators are good. When my plastic o ring holders die ill be switching to those.
