What a treat to see such a fine build first thing in the morning.  Looks very potent!

I have the Oil cooler, but for the Dyno bench test I prefer take it out. Less stuff around is better  C:-)
I hope is powerful as it Looks! :-)

Looks great :)
What does the dyno say?

Do you mean the Saenz rod are 120 gramms lighter than the original ones, or did you reduce the weight of the Saenz rods? And did you change the displacement?

Ciao Mecky!


We will make the dyno test in September. I'will keep you posted guys!
Regarding the con-rod Saenz I must tell you, they are lighter than the gordini one! Only 460 grams! I use to run with the stock R16, 560 grams. Hope i can feel the difference!

Thanks everyone guys! I am glad you like my job! The next post is going to be a video of dyno test. Whatever is the result, we will finally know how many steam we could squeeze out from one wedge! :-D

That is a beautiful looking engine.  I can't wait to find out what you make for power out of the wedge head.
1969 Europa S2 - 54/1869 I still can't believe I own one.
1978 Austin Mini - 1275, big brakes
1991 Ford Explorer - Lifted on 33s, custom lift and radius arms
2005 Chrysler 300C - chipped, lowered 22s
2003 GMC Yukon - chipped, lowered
You could say the stable is diverse

It is nice to see someone building the wedge.  I have had several Europa race cars.  One I found in pristine condition in a time capsule, preserved as it had come off the track in the 80's- a LEGAL SCCA E Production car that was a major contender in the region back in the day.  This car was scrutinized to the nth degree, and they questioned the carb/manifolds and flares.  The "Hermes" kit was allowed since it was somewhat of a factory/dealer option.  Of course this engine was built to the max on the inside- my limiter in this car was valve float around 8k on the long straights.  Gordini or other engine swaps were out of the question in real SCCA racing- vintage clubs either don't know or don't care about the swaps.  Here's my 67 S1 EP race car as I found it in the previous owner's garage!  I miss this car.  I sold it to an old racer in our club who always wanted it.  he was killed by the ramp on his race car semi trailer and I later saw it for sale at Wire Wheel.  Someone got a nice car.

Hi Valero,
How is the build going?
I look forward to hearing how the dyno run goes.
Cheers
