Cool Intercooler Outlet

Hi Sharksters,

I wanted to give a little update to the SC project by posting a pic or two here and there. Anyway, the attached pic is of the Intercooler outlet manifold that connects to 4 injector blocks which mount to a plate, which in turn mounts to the heads.. One IC Outlet manifold per cylinder bank in a 928 32V....

I have not done lengthy CFD studies on the shape, but it maximizes all the available space in the engine bay, and has some other things things incorporated for good flow based on the space available..

I did not want to cut the bonnet open to advertise anything under it....

I have more parts in final review, and expect to sign off on all the final drawings in a week or so..

Cheers,

Nice work. From yur description I kind of understanding how the part functions. I'm having a hard time translating that to the CAD drawing. Where do the injectors go? Is that a seperate plate?

Rich, when the IC is set in there, how much clearance is there between its lowest extremity and the openings that lead to the injector blocks?

My guess is the injectors would go in bungs on the other side of the plate..abeam the intake ports, but out of view on that picture.

Nice man!

Default Injector block

Hi Guys,

The injectors go in this block.. The block bolts to the bottom of the IC outlet. The top is the "tray" portion, and there is 1 block per cylinder, 2 injectors per block.. The fuel rail and injectors will be on the sloped side, and the rails attach to the IC outlet.. Incidentally, the edge of the top of the IC outlet is close to the height of the valve covers..

The depth of the IC outlet is 1.5 inch from tray face to the inside floor...

Again, not much space to do much, but enough to get it going..

The IC bolts to the top of the IC Outlet actually, the entire upper assembley of the cover, the SC mount plate, and the IC bolt to the IC outlet...

Picture a spider, with the body of the spider being the SC, the the upper legs the IC, and lower legs being the Injector blocks....

Thanks, HTH

Why 3 holes Richard? Why not one large oblong one?

H,

The IC outlet has 4 holes, one per cylinder.. The 4th is a bit hidden in that pic...

Hope it all fits!
Its going to look great when done, very "one of"
Nothing like bolting it up to be 100% sure..i will say that much!

The stock box was carefully designed with vortices in mind. I suppose if the existing twinscrew ic housing works this one can only be an improvment and it really will look nice.

Thanks for the supportive comments guys..!

It will be a very tight fit.. I have even considered not using washers on the motor mounts for extra clearance...!

There will be some interesting machining to get good flow.. however, the distance from the inlet valve to the IC floor is the same all around.. Similar to louie's ITB setup... The Injector blocks are in essence an extension of the intake port runner. In addition, there are no turns after charge cooling except for the short turn casted into the head...

makes sense....? or clear as mud...?

Good thinking Rich. How about a redesigned crossbrace? there is a BIT of room wasted down there. The mounts are actually very tall even compressed, so it may be enough to replace mounts with a far smaller item? Essentially it's just a long bolt ....

Talking SC System Cover

Ok,

To muddify some more, I decided to post a pic of the syatem cover..

The SC will mount upside down, and blow up into this cover. The cover then directs the charge sideways,and down to the IC, which is sandwiched between this cover , and the IC outlet posted above...

The holes in back of the cover are for the bypass valve/s.. the odd ends on the right (protrusions) are mounts for the throttle cable that bolts to the current 32V manifold..

Now is it as clear as mud...?

Looks great. As I recall there is a good two inches if properly done when trying to lower the engine.
