I taken some pics and some rough measurements for Brad on the Hartge H27sp. In the Hartge catalog Hartge claimed with itbs to do 220hp. With out itbs on a H27 it produced 205hp. I did a little research H27sp. I read Hartge offered a street and a race cam. With the Hartge race came it produced 245hp.

Here are some Hartge m20 itbs measurements. I will later take some more measurements.

The horn intake side and other end. Front out side 67mm. End of horn 46mm. The U section intake F. 45mm R 41mm.
The throttle bodies F. 42mm R. 38mm. It looks like it was designed for a 731 head.

Crazy cool piece, too bad you don't have an M20 to put it on!!

So didn't quite follow the F & R reference( could be the beer... ) the throttle plates are 42mm? That looks like a 885 port to me ;) and that looks like it could be a boost friendly setup 8^)

Raul, beautiful piece, congrats, btw, there's a set of m20 Hartge headers in japan auctions.

Great pics Raul. If I had seen that auction I would definitely have bid on it :-)
Can't wait to see it setup on a stroked m20
