Title: Single port 1679cc type 1 engine... 90Hp. Post by: Crazy Mc.Stairs on August 28, 2012, 21:12:34 pm Hi all,
Today I've dynoed a 1679cc engine I've made for a customer, and it pulled 89.8Hp at 4550Rpm and 155Nm at 3200Rpm with stock size valves and single port heads. This is a daily driven car, it's a vintage engine (Theo Decker) style, not a race engine! ;) Cheers, Christoph Title: Re: Single port 1679cc type 1 engine... 90Hp. Post by: Jim Ratto on August 28, 2012, 21:36:14 pm Impressive. I have a 88 x 74 single port in my cabinet, 236' @ .050", .480" @ valve, someday going in a nice '66 Bug. This is encouraging. 8)

Gentlemen step up to the bat and purchase MY heads from the 70's... 1600 s/p kadrons 15:01 @ 87 mph in Notchback. Freshened by the talented Fred Simpson and now just need a good home with Love.

Will be putting my 1835 single port with Teo decker kit on the dyno at JPM in oktober. To give you a hint it wont start with the six volt battery so I have a 12 volt to get it started then I leave it to the magnet when i change to six volt. Drove it down to germany last spring for Maikäfertreffen with lots of power and great gasmilage. Would like to hit over a hundred but who knows.

Post by: youngnstudly on September 03, 2012, 06:41:55 am I hope my 1915 SP makes some power similar to that! Sounds fun and looks very cool too! I like the car as well.
