Well lets see here, its coming up on three years since I bought my VDub trike. I did a trade with a fella down in Denver Colorado and I knew there were some odd quirks that needed to be fixed, but I figured I got a good deal doing the trade.
The guy I got the trike from had purchased it about a year before I got it and he had bought it from the original guy that built the trike. He got paper work for the engine that stated it was built by a well known Denver VW shop called Painters Grinding. I looked the paper work over and it showed that it was a 1915cc with tons of machining, hi performance 40mm x 35.5 heads, stainless valves, Engle W120 cam, full flow oil pump, etc...
It was mid August when I got the trike that year, so I really didn't get a good chance to ride it much until last summer. After some short rides I really really felt that the engine wasn't at all a 1915cc and it sure as hell didn't have an Engle W120 cam as it had a smooth idle. I came to the conclusion that if it was a 1915 there was something seriously wrong with it.
So, a couple of months ago I pull the motor and tear it down...........LOL, yea okay, I was right. It ended up being a frigging 1641 with an Engle W100 and bone stock 043 heads.
I knew it didn't have the power a real 1915 would have.
It did have an excellent EMPI "bubble top" all aluminum case and an 8 dowel counter weighted 69mm forged crank though. So I decided to build me a decent 1835 out of that combo. Added an Engle W110 cam, the 92mm AA pistons and cylinders, straight cut timing gears, hi performance big valve heads ported with 12mm long reach plug bosses, and thanks to our own Deathbysnusnu, a great set of 1.25: to 1 set of Scat rockers. I ordered Chromoly cut to length pushrods as well.
Well, I finally got it fired up Saturday to run the cam in for 20 minutes at a mild 2000 rpm, drained the oil and filter and put new filter and oil in her and took it out yesterday.
Holy cow what a huggggggggggggggggggggggge difference!!!!! It is 10 fold the engine it was originally! First to second and second to third it pulls the front wheel right off the ground and will do 0 to about 60 in a city block.
Went up the highway a little and came up on a pickup truck doing about 50. Got the chance to go around and hammered it down, pulled out around the truck and once I got past, which was a couple of seconds, I looked down to see that I was up to 100mph.
Yep, that'll work.
Sorry for the long a$$ read but wanted to share this tale with ya all.
