Hi Guys, just lettting you know I still come on here on a daily basis to check whats happening in the real t4 world

The reason for not posting much is lack of reason, any more than I've posted would be spam ,I dont like getting into the "my things bigger than yours" situation which often happens

I suppose an update is in order tho' Russ finished the season runner up in the VWDRC championship Pro class, his motor is still together still doesn't blow the heads off.
I suppose there's only so much you can say about using big cylinders before it gets tedious. when I say you can use 104mm on the street,turboed and they wont blow, noone has to believe it.
But when someone says you cant then I feel i have to correct them as I have real life experience of it.
BTW cylinder sealing on Russ' is the same as Martin's (great minds I think)
Same with cooling Porsche fan setups have been used for decades now and like all things they are popular for good reason.

BTW have you seen the sealing surface of 96's or T1 94's? they are like a cookie cutter the walls are so thin.
Using Porsche heads has allowed better airflow, better combustion shape,better exhaust design and better clamping capacity on the cylinders.

Wally you need to do it man!! its not too hard you're half way there already

Great to have you still around. Glad I could trigger you to participate again

Funny thing is, a friend of mine (and also a member here) showed me a set of an old, but still never used mahle 103mm set. Wall thickness at the head was a stunning 5,0 mm! I think that a great deal of the experienced troubles therefore probably ly into the poor quality steel and thinner linings of the cheaper US made 103mm sets, without wanting to discuss to merits and pitfalls of the steel 103 sets all over again, caus I do also see the potential problems with them.

Haha, yeah, you make it sound so easy. I guess you mean s/th like this:

For the 'big' motor, I save my efforts for the apfelbeck heads. Otherwise it would lead to too many projects and nothing gets finished...
