Sex sugar blood magic .... and cams ...

Dear all,

we where about to implement modern cam structure and strategy into our flat six classics.

What we achieve is a plus in power and torque as well as a more in drivability and performance culture.

Beside the a.m. aspects I'm sure Chris would confirm that these cams are running very quite mechanically and are generating a usable idle also.

The goal was to have a lot of lobe area, this with less possible duration while using latest ramp philosophy; respecting the rocker geometry and spring pre load in relevance to the max possible positive acceleration.

Any cam can be symmetric or asymmetric in:

Lift
TDC Lift
Duration
Lobe area
Or even the open and closing ramp structure

Some of my cams are asymmetric ....

So no dark magic involved just 33 years experience in engine building and cam architecture / construction mainly for boxer engines.

By the way today we have finished the machining of some parts that will go to Chris too after assembly is done:












Best reg.

Dirk

To whom it may concern:

since a couple of years i am a silent member of the forum and i may not hold back my expirence with dirks camshaft.

i got in contact with dirk after i read a couple of posts in the forum and due to the fact, that my car wasnt running quite well (runs well to rich, nearly undrivable after a coldstart) i called him and explaint my problem.

long storry short.

after a couple dyno runs in combination with some adjustmens on my blwur his team figured out the problems and as a result it ended up with 413hp on the flywheel. modification on my car was a Hyward&scott header with 100 cell cat, doughterty 993ss cam, BL wur, 1.0 bar waste gate spring, slightly increased compression close to 8:1, fvd k29/27 turbo and a single mass flywheel.

With this configuration i drove the car 1 year and decided to take the next step.

dirk convinced me to perform a slight head porting in combination with a modification of the cylinder head gasket (nirest-rings or so called “le mans gasket”) and gt-2 head studs (in order to increase safely boost up to 1.2 bar if necessary) to use his camshafts to get the car close to 450hp.

finaly the car produces 469hp (tourque 726 nm) with 1.05-1.15 bar of boost on the dyno.

fantastic!!!!!!!

i honestly have to say that dirk isnt cheap, but if you have played with low priced parts as i did i must say: he isnt expensive and worth it.

also keeping timelines isnt his strength . for instance i was waiting on my car a couple of months but if you have the choice to vist his company and his team you may understand it isnt easy to manage all these crazy projects in combination with different other businesses.

as a result:

modifying these cars and engines ist art and dirk is defintly an artist.

Good to hear you're happy.

Thought for a minute this was going to go bad...

What did you do with those 993SS cams??

Were the 413 and 469 HP numbers both flywheel numbers?

We continue to be impressed with the Edelweiss camshafts. Tried-and-true engine packages are making better torque in low- and midrange, more power in the upper rpms, and overall feel more lively and responsive. Idle is still smooth and civilized at 900-950rpm.

Recently got a shipment of Turbo CIS camshafts in:
930/1 profile -- maximum recommended camshaft for use with factory CIS injection
930/2 profile -- maximum camshaft for use original factory 97mm 7.0:1 pistons

We used these 930/2 cams in a 3.3L with 36mm ported heads, aftermarket headers, K27, and upgraded intercooler. Compared to an identical engine with factory SC cams, we had +15tq at 3,000rpm and +16hp at 5,500rpm.
