Got my heads half done via my friend last night

They are still rough and the final port work isn't done!

Got new JM-7 heads in them with one full radius and one 45 degree cut on them.

We where down at JPM (www.jpmotorsport.se) for their dynoday and I get them flowed.

Please give me your thought on this.

The flowfigures are cfm at 25"

lift -- intake -- exhaust -- i/e-ratio
2mm -- 40.1 -- 39.1 -- 97%
4mm -- 78,7 -- 61,4 -- 78%
6mm -- 110,8 -- 83,5 -- 75%
8mm -- 143,6 -- 103,7 -- 72%
10mm -- 167,9 -- 119,7 -- 71%
12mm -- 180,3 -- 132,7 -- 74%
14mm -- 190,4 -- 140,6 -- 74%
16mm -- 196,4 -- 146,6 -- 75%

Some pictures on the head

Let me know if you want pictures in any other angle

Hey Jonas, here's the link to where I borrowed your flow #'s for comparison:

Jonas, you seem to have the bottom cooling fins welded together from exhaust side. Did you do it also to spark plug side? Or did I just look wrong?

I am also thinking to cool the engine from under the cylinders (like klaus system is), have you thought about that?

Richard >> I guess I should be pretty satisfied with the numbers then?!

func412>> That is correct, welded on both sides

No I haven't thought of cooling from the underside..

Going VEMS?
Doing something in SS?

Buying a one-way ticket to Brazil because the snow made you snap?

Hi Jonas, let me guess, you want to build another turbo header?

Nice 1 to Jonas N for the mag feature.

Race bug looks exciting!

Yes, because of the new turbo being twinentry I need to have equal length header to use it all out! And I want to have the turbon in another place

The race bug is sure fun

Here is a thread about it.. it is in swedish but you can see the pictures

Today I made my self a collector for the new header... in paper

The real thing will look something like this

It was really hard getting the pipes round.. but you get the idéa

Update

A while ago I bought my self a used TIG welder. Today I tried it out

This is the result for today

A little contact with the electrode a couple of times.. but a bit of practice and this should be really nice

Btw, this was the first time I have ever tried TIG welding (no previous attempt at gas either!)
