CROSSFLOW extractors

[slydog 7,873]

OK all this info is really good,so it seems to build the worlds most powerfull crossflow,a big turbo efi set up or 4/71 blower drive system,im really only interested in a drag racing engine as this type of motor is not a daily ,what is the most hp anyone has achieved from a wild crossy ? 500-600 hp ?

 

LOL I hope you have deeeeeeep pockets then.

 

Oldie but fitting TBH. 200 cube T4 turboed xflow...

 

 

 

1min40sec's is where it's at.

[CHESTNUTXE 7,312]

nice ,so how much power did the corty have ? 

[Mixalis 266]

Round the 900hp mark the general consensus was from memory

[CHESTNUTXE 7,312]

awsome figure,and it was a 3.3 wasnt it ?

[CHESTNUTXE 7,312]

Hey guy's does the EFI alloy rocker cover fit on any crossflow or is there some mods needed ?

[slydog 7,873]

If it is for a drag engine you will need a spacer when you fit roller rockers so instead buy a Aussiespeed unit that fits straight up.

im just talking in std form,the wreckers up the road has one and its in good cond i want to grab it  this week.

[wagoon 2,429]

I found that the efi one hit the standard weber carby on a standard manifold, didn't bother to find out what I would have to do to make it fit although it should be to hard to make it fit with you favorite hammer. It's a worthwhile upgrade though as the tin covers can leak a fair bit.

[Ando81 2,949]

I've fitted an alloy cover on an old xe I had years ago. I just used 2 base gaskets between the carby and standard manifold. It lifted the weber up just high enough to clear the rocker cover.

[CHESTNUTXE 7,312]

ok cool good info,because i see a lot of people putting those covers on ,they look space age !

[CHESTNUTXE 7,312]

I spent hours digging in the wrecking yard today and found a heap of goodies to pick up on thursday,3 x efi crossy covers in good nik,1 set xf extractor's,1 x e1 alloy head,1x e2 alloy head,1 x xe ghia bonnet stashed away but needs a bit of work,plus heaps of other stuff like badges ,i was hoping to find some esp stuff but no luck,i see so many ea to au stuff there,but xd to xf has really dried up.

[gerg 10,871]

Yeah tell me about it... The only x-series around metro area are XG and XH. Need to go to the country to find the good stuff now.

[slydog 7,873]

And no we are keeping it all cos it's getting thin on the ground out here too.

Question on this, if someone was keen on using the factory tin rocker cover for appearance purposes, how much would this need to be spaced up to clear roller rockers? Im guessing this would obviously depend on the cam lift and whether or not the rollers are adjustable? 

[slydog 7,873]

Ummmmmm Id suggest the tin unit fits OK as there used in speedway alot.

[ando76 4,354]

Yeah they fit.  ballpein hammer fixes where they contact.  Dodgy - but hey it works

[Mixalis 266]

Oh ok there you go. If you wanted to sort of avoid any chance of clearancing issues tho, would a 1/4" or 1/2" spacer with a rocker cover gasket on either end be a good place to start or overkill/problematic in the future? 

 

PS not a problem of mine atm, was just curious now that it has come up

 

Cheers

I think Aussie speed does a 6mm and a 10mm alloy spacer

[ando76 4,354]

In my experience no matter how gentle you are with the tin covers (genuine factory even - chrome ones are worse) they nearly always leak.  A spacer would more than likely make this work.

 

The EFI rocker cover with 2 rocker covers gaskets and a few seconds with the die grinder works well and will fit under roller rockers and up to .600 lift (I've never gone past that because I am soft).  This will also fit with two barrel carbs that are spaced as mentioned above.

 

If you want great looks and a cover that never leaks, clears rockers without issue then the Aussiespeed units are bloody hard to beat in my opinion.

[Mixalis 266]

Cheers Ando, you're right mate I've had numerous leaks with the tin one, even now with the rubber gasket. I have redone it with a bit of Polymar as I've heard good things but not going to hold my breath if its a design flaw. I just love the original look thats all. Anyway when it comes time to cross that bridge ill have some info handy. 

[CHESTNUTXE 7,312]

Where abouts does the efi cover need to be ground a bit  to fit on the carby set up.or if your using a aftermarket manifold and say a 2 barrel holley maybe this mod isnt needed ?

[Mr Polson 10,214]

I have a EFI cover on my carby XF, factory setup, only needs a little taken out of it where the front of the carby doesn't clear it.

[CHESTNUTXE 7,312]

Cool

[SLO247 1,713]

I pulled one off a carby XE and it had a thick rubber spacer under the carby. Who makes that?

[slydog 7,873]

As said before and as above there is none better TBH.
