JayCee short IDA manidfolds

[jason]

Anyone using these yet? Do they fit a regular doghouse shroud? I have a Thing shroud I want to use them with. I emailed Jack and he doesnt know if they would fit. I have a set of Scat and DDS shorts, they both hit the shroud. I also like that they are not backwards like the DDS and Scat.

[bugguy1967]

Sucks that he wouldn't know. You'd think one would check for that kind of thing when designing a manifold. I saw these at Irwindale at the Pierside booth. Call them tomorrow to see if they know. I'm interested to know too.

Funny. I've seen pics of the Deanos with a stock shroud before and everything cleared.

If they end up not clearing, Berg's short reversible manifolds will clear for sure.

Looks like there is a lot of material on the mounting base, if they hit, maybe they could be machined to "lean" away some.

[jason]

I tried the Scats and the carb rides on the shroud seam. I also noticed that I had to put the carb on the same time as the shroud to fit it in the little pocket of the shroud. That would be a real pain. I could put time serts in the manifolds to cure that instead of the studs. I am going to take my head tin off and try the DDS one. It is too big to fit in my opening. I compared the two and they were almost identical. Shape is different but same angles.

The motor in the picture runs the Scats and a Scat 36er shroud. Checking what fits with the Thing shroud. I don't want to grind or bend the shroud. You would think that someone would make a short IDA manifold that fits a doghouse. There are already 5 companies that make them that don't, maybe 6 now. Not bashing just saying.

[jason]

I called Gene Berg's and they said their shorts will hit and you have to use a 36hp one but you know they won't recommend those. So they basically said they make a manifold that you can't use for street. I also called Pierside. They said they haven't tried it on a stock shroud and thinks they won't fit.

If I recall correctly back in the day it cleared on big motors but guys with smaller motors ran a head to manifold spacer, was either an empi part or a shop in CA was cutting them as needed don't remember but it still kept it lot shorter than tall manifolds. I guess worst case you could run those crappy center mount shrouds....if they still make them.

I think you are right about the big motor little motor thinking. I have a bit of compression on the motor. It is slightly smaller than stock. It's only a few thousandths smaller. I was thinking maybe get the GB-590's and machining the thick a** tops down. Make kind of a medium size manifold.

[mark tucker]

take your intakes and angle mill them so they fit.easyly done some that had to move inward about 3/4" but remember both ends need milling to keep the carbs uprightand not tilted(unless you want them tilted for some reason) or you can have some angle spacers made, many ways to skin a cat and not get scratched.

[jason]

I am trying to do the least amount of changes. I know nothing fits like it's supposed to, for the amount of some of the parts they should. I could probably get away with milling just the bottoms, it doesn't need much.

[mark tucker]

it's easy to figure, just use some masking tape and add some to the other side that needs to be lowered. about 1/8" wide and add more till you have about .060 clearance where you need it then mesure that and that is the amount that it needs angle milled. if it's .060 thick then angle mill it 0.0-.060 , you can then check before milling to see if the carb flange needs milling any to "upright " the carb. sometimes other tings get in the way and you end up milling half as much on the carb flange. you can use the tape thickness method on both ends before milling if it's close everywhere to get it the best it can get. remember when you pull the top of the intake outward the carb top comes out also almost 2x as much as top of intake does, and milling the top leaves the flange&carb bottom in the same place but the top moves back in to be aligined if you desire it so.or a little less or more depending on what you want&do. it's simple but some thinking is required.

Cut the empty space off the shroud. It does nothing anyway.

CUT A THING SHROUD??!! MURDER!

[mark tucker]

what is so special about a thing shroud?it's no different then the intake & exhaust that has already been thrown away........but milling the intakes would be my route

[jason]

Nothing special just costs more. It is almost identical to a fresh air one. It still has the pockets everyone says aren't there. Visually identical inside. Maybe the vanes are flatter, look the same to me.

[mark tucker]

I use the dogystyle 36 on all my stuff so I havent had any of those issues. but the one I did have to move about 3/4" was a 2386 in a 912 porch and the hinges were eating up the filters badly.so... I moved them inward. yup inward.it had a 911 type shroud.

[jason]

Anyone know off the top of their head the height of cb tall ida manifolds?

[vwracerdave]

Look at the orientation of the carb mounting position on the JayCee short manifolds, then compare it to the Scat/DDS short manifolds. Notice one is opposite of the other. Gene Berg manifolds you can mount the IDA's in either direction.
