Lol if that is an 1100+ps cylinderhead then I'm on a winner as I can see 3 things that can be improved upon already.

Every cylinder head is 1100+. Just depends how much boost you cram in there, doesn't it?

Well if its a copy of jens head, than its a copy of the fastest Audi in the world...

Ha Ha, they don't even start by welding up the ports to achieve a proper shape!

[JP]

^^^driftin jo mistake no1 spotted. The other two are to do with the shape which comes more from experience. Saying that it is not a bad head but for that money you can have better.

[campbellWS]

that looks good!!! how important is it for the five ports to all flow the same? i would like to do it myself but fear problems occurring, can someone suggest a person in the uk for a similar job?

[djh]

person above your post is quite good

That does not say much about the head though.

Somewhere down the page, ... if you find another head which flowes better than that one, money back :-)

Get the Run DMC on, I see a challenge brewing...

RWD19T did a fantastic head job on my RS2, can't rave enough about it.

Which part of the intake port you prefer filling by welding? Raising the port floor from port opening to short side turn or filling the roof at the valve guide, long turn and bowl? Long higher arc to the valve or lower straight shot?

Only.that it makes ALOT of power. he had 256km/h end speed @402m as a.record in the URS4.... Around 1500kg...

That still does not say anything about the head. Or do you disagree?

It says it makes alot of power. or is that false?
