another custom H series intake manifold
good for n/a setups between 95mm to 100mm stroke. also good for F/I applications as well.
this one has a 90mm mustang tb flange. getting ready to do one w/ 76mm honda tb flange.

Jay West is gonna do some testing for me in the meantime on his stock block engine but i think he will find the reworked stock upper/lower manifold to work the best on the stock displacement. Dave will be testing the manifold above but w/ a 76mm honda flange very soon as well on his 95 stroke engine so that should be a good test for it. both guys are doing back to back comparisons to the euro r manifold and Jay is also comparing to the skunk2 manifold as well i believe.
btw i have decided to make a tb adapter plate instead of a regular honda tb flange. this will allow you to bolt any honda tb up to 76mm onto the exsisting 90mm mustang flange.
the honda bolt pattern is directional, meaning whichever way the flange is welded onto the manifold thats it, its done and you wont be able to rotate the tb if needed. also if you get a manifold w/ a honda flange and later decide to go up to a 80+mm mustang tb you will need another manifold or at the very least need to cut the flange off and weld another one on.
the adapter plate solves both of these issues and makes the manifold more versatile.

thanks man
im gonna be shipping out some stuff next week for Jay to test, been pretty busy trying to keep up around here working on several manifolds at the same time lol
sending him 3 different plenum setups.
~ ram air style 90mm
~ under hood style 90mm
~ stock plenum 67mm (i think this will work the best on the stock block setup)
~ 1" plenum spacer to test w/ the stock plenum
~ 67mm honda tb adapter
just about finished everything and i will take some pics to post up next week. just working on the cnc program for the honda tb adapter now.

sorry guys, i didnt get much accomplished this week. the family was sick all last weekend into this week, then we lost power for a couple days thanks to the snow.
i will be back at it on monday. not sure if the tb plate program was written or not, most likely not w/ all the weather messing up everything.
i will update next week.
