aircooled WBX 2546ccm

[aircooledWBX]

Well, I decided to keep my T4 Pistons and Cylinders
Anyway the engine has to be solid.
My goal is about 160hp and a lot of torque.
I want to use a low compression ratio,and low valve lift to keep the pressure in the cylinders low.
I think I'll use 9,5:1. Any cam suggestions ? I thought about a CB/Eagle 2244:

On this german Site, i found other Facts than on the CB site:http://www.eckstein-kuebel.de/NWT1.htm
It sais 9,73mm Lobelift = 0,383"

CB sais:
Eagle Racing Cam - Adv. Duration 300° / Dur. @ .050" 250° / Lift @ cam .370" / Lift w/1.1:1 Rocker Arms .407"

Where is my mistake ? Does it have .383" or .370" lift @ cam ?
Any better cams, or advice ?

Regards,
Nick

New 100mm Pistons:


and some work on the Case:
before:

after:

So now you need some 100mm barrels.

[aircooledWBX]

Damn right Deutz 912 i think !

[Unkl Ian]

Yes, you'll need new ones.

Some guys like used cyl, because they can
bore them to 101.6 and use 4" V8 pistons.

[aircooledWBX]

New ones aren't too expensive. I think about 50-60€ each.
4" bore with V8 Pistons sounds interesing too
Mine are from the 911 Gt3. Fortunately a snip

Hi there,

after a long time of nothing happening, here are some News. I'll try to use Porsche 964 cylinders instead of Deutz.
Head Stud pattern has to be slightly redrilled.

A first idea of a clamping fixture:


The heads were tig welded, cause i don't wanna use the pre-owners idea of hemi chambers. The Edge on the Top is for a second sparkplug:


To get a bigger gasket face with bigger inlet ports, there was some more welding:


Thanks for any tipps or comments !

Off Topic question:
My brother builds an 78,4x90,0mm 2,0 Type 1 with Oettinger Nickies. Problem is, he needs a set of good but payable 90mm Pistons, cause his set has different compression heights. Anyone has an Idea or an offer ? used Porsche 911 Carrera 2,7 Pistons ?

if its just the pin height off, it maybe easier to alter the rod length/offset bore the pin bush?.......

Sorry, but i don't understand what you mean

Hey Nick!

Is that the "Bernardo Proficenter 550" machine you recently got hold of?
Looks bigger than I thought it was. Is it any good?

Like I told you before, I totally dig your project, and am looking foreward to race you next summer

Keep us posted!

[aircooledWBX]

Hey Arild
nice to hear from you ! You're right, thats the Bernardo. Sadly the mill is not stiff enough to work on real high precision things. But I'm satisfied with it !

Next Summer racing each other on a racetrack would be great !!!!!
I changed my suspension to KW Coilovers, so handling is much better now

Some work on the cylinders done today:

Seems to fit:

Sadly found a little crack Don't think its caused by the machining. Seems it has been there before. I suppose unsafe keeping/disassembling of the pre owner is the reason:

[aircooledWBX]

Today i began to lathe the cylinders. I did not have any technical schooling,
so everything is learning by doing Concentricity was about 5/100 to 1/10mm.
Hope you are pleased with my work

[aircooledWBX]

Do NA Engines not interest anymore ?
First Cylinder fits:

[Wally]

Your cylinder is upside down

Nice work man!
