3 litre wolf efi crankcase injected 3 litre build

from wat i understand mounted normally it would have to turn from left to right
but if you mount it upside down you could use it the same as the early 2.4 intake horn,s

[mrcrsr]

i could flip it, would be easy enough to do. anyone have the pics of what the stock arm looks like on the etec- i have a friend who is supposed to get me the factory tps and arm. as far as making the plenum larger i could, have to find thicker material as i do have more room w/ this intake.

[PanRonnie]

wat if you create a reed plate like in the foto out f a 10 mm aluminium
plate and weld a box on the outside of
aluminium sheet 10 mm or maybe thinner
http://nl.rs-online.com/web/p/aluminium-sheets/0188321/
weld on frontplate out of 10 mm where you mount on the intake
make it large enough to keep the mounting bolts on the inside

[mrcrsr]

the question is how much plenum is enough, lol! i do have a lil more room w/ this intake but still need to add in velocity stacks, have to get a minute to go on ebay, the tube od is 2.5" . the reed plate i have(was going to cut open the inside) is .675" thick so wondering if this will build enough of a plenum in conjunction w/ the etec intake manifold. any ideas what the plenum volume should be? i think charly said it should equal the displacement of the engine.

Give me a half hour ill post a pic

if you keep the edges of the reed plate square
you can mount the velocity stack inside the plenum
like in the pictures
1 plate with a rounded edge and the spacer-plates with the same dimensions
this way you can add tuner length to where you want to put it
this was basically my idea for the new plenum design
you can increase the plenum volume by making the box wider to the side,s
how much is enough ?
maybe as much as you can get away with
you can always add in more spacer-plates/velocity stacks inside the plenum
which will increase tuner length but also decrease plenum volume

definetely not enough room for that ronnie! my old engine running a factory 300x plenum w/ a 1" spacer would touch the front of the cowl. it looks like i'll just add the .675" spacer to the plenum and call it a day. finally got the parts yesterday for the etec linkage, might as well not of, that whole linkage setup sux. looks like i'll end up machining a throttle arm and relocating the tps somewhere else, perhaps on the bellcrank or main throttle arm, worst case i'll use what the factory '02 and up 3litres/optis use, w/ a linkage off the throttle arm

just wanted to give an update, haven't had much time to play w/ the setup, been busy w/ work, but i pulled 5% fuel out of it above 6k rpm, boat went 103 on the last run, just pulled it apart and getting ready to install a 15" midsection over christmas break. i'll get some pics up soon

[Stitch King]

boat went 103 on the last run

That's with two people in it from what I heard...

So it should be even faster with a lighter load.

[mrcrsr]

2 people and 25 gallons of fuel, so the boat wasn't lite, the best part is the acceleration though. i know i have to change the intake manifold so i didn't want to put a lot more time into tuning the top end. i'm curious to see what i gain in top end(if anything) from going to the 15" mid, its gotta do something getting the big 3 litre cowl out of the wind.

[Stitch King]

Should lose a couple pounds with the shorter mid too.

[mrcrsr]

the 15" mid is much lighter, i carried it in a crate of parts, i could barely lift the 20" mid off the boat, probably also has to do w/ the thickness of the casting

Charlie,

with Ken, loosing a few pounds can only increase the bottom line..................

MORE @ W.O.T. !!!!!!!!!!!!!!

Did you start to machine the pivot tube yet ???

[mrcrsr]

haven't had time gary, in the middle of building a couple of 280's, hopefully i'll be done w/ them and have them installed/running by the end of the weekend, and then i'll get back on the skater project. i need to shim up the swivel bracket over 1.5" on the lathe table so i need to figure out what to use, if i can't get it figured out i'll have to go harass charly, lol!

[Liberator*21]

Charlie,

I use a hex hd bolt with the head shaved flat & square on a lathe and a flanged nut or extension nut when an adjustable shim/spacer/riser is needed hopefully that's all you'll need. Good luck on the 280's.
