Acki, I could not translate your comment so I don't have a response. Pauer, yes I have the port CFD. Actually my friend Brad Garska did the analysis and I think it was in ANSYS. No transient analysis with dynamic movement, nothing that involved. It is all at steady state and simple. I am traveling ...

This was recorded yesterday. Some balancing needed but better than expected. Working on a CAE solution for ultimate power. I will post my progress in the future.

Interesting comment on the head. What are your basing your comments on? Actually it is not my first but the head is primarily PBS machined so I am interested on your response. I have to ask too, what is your current hp rating and are you running a 1.5ltr? I only look at data so please let me know ...

Here is information that may answer your question

The pictures really tell the story on the head:

Hello Ulix,

Are you the same Ulix with 95whp on the US web sites? Thanks for the propt reply. We have a holiday today so I am spending time doing research. I agree on your points but spec wise I see the main differeces between my engine and a full race engine is compression, lightening, and ...

This has been discussed but the link went in the direction of piston speed etc. I have 97peak whp (approx 115hp (sae) crank)
Here are the specs:

***I rev this car to 8500-9000rpm nearly every shift*** I wanted to get that off the table
1500cc
10.3/1 cr (domed pistons)

Here are some random photos. The CAE stuff is from work that my friend and I have done. The blue 74 is owned by a very close friend and is probably the best US car. We are all automotive engineers. Thanks for the interest.

My German is quite weak but I think you asked how long have I had the car, I started building it 16 or 17 years ago. It is a club car (street/race). It has been "finished" for 5-6 years now but is now showing wear and tear on the body. I appreciate the contact help. Thank you.

Does anyone have the contact info for the owner of this car? As strange as it is I have a very similar looking car in the US. I would like to compare notes if possible.
