Default 1600 wot can I do?

Hi I have a trike with a 1600tp type 1 engine. I'm intending to do a few RWYB's next year.
No what I'm wondering is, if I get into it, what can I do to the engine to get the maximum performance out of it . I don't want to go above 1641, and I want to keep a single carburetor. So apart from that what do you recommend for performance?

A single carb with the long inlet manifold will restrict it. If you swap to a twin choke single carb, you can get icing problems in the winter. So you might have to go with a pair of Weber 34ict's. The exhaust is the next thing to restrict it, if you put a tuned 4 into 1 exhaust on it, you will get more power. The beach buggy twin cannons look good but strangle top end, don't know what you are running now. Until you change these, any other mod's are a waist of time

I agree with a pair of weber 34 ict carbs. From experience fit the thicker gaskets between the carb and manifold-these help with heat soak/hot starting. Balance/set up the carbs with the balance pipe blanked off then refit for driving-makes it smoother.
And yes a nice 4 into 1 exhaust will do wonders, but not too large in diameter.
And fit a electronic ignition distributor, I used a 009 and played around with the advance springs until I was happy with it all.

Happy trike-ing.

There’s some good books on on modifying aircooled engines:

How to Hot Rod Volkswagen Engines https://www.amazon.co.uk/dp/09126560..._51wwDbJJ4V85N

Vw Beetle Performance Handbook (Motorbooks Workshop) https://www.amazon.co.uk/dp/07603046..._12wwDbGXNMAA6

Everybody seems to say this but I had a 32/36 Weber on my 1.6 tp Bay and NEVER had any icing issues, even when I was spraying de icer on the inside of my windscreen going to work on a 6-2 shift. The heater tube under the bus was as airtight as a Brandy Snap!

I just thought I'd mention it.

Well, manage to write of the 1600 trike, so now got a 1300 twin port type one engined trike.

What are my options for this, quite fancy keeping the capacity the same, but what can I do to the 40 horses to make them better?

All the same stuff

Best money would be spent on pepping the heads, nice valve job and a little port clean up.
87mm pistons
Twin carbs (I liked Kadrons)
1 3/8" header.

H40/44eis or Kadrons are fine, simple to tune. As are the Weber 34ict.

36idfs would be a better, a little more difficult to tune though...
28mm vents with a SVDA distributor is a brilliant setup for street manners.

If you want to stick with a single carb and 1641cc

This is what we raced on in the Beetle Cup

1600 engine cases
Standard Crank
Standard con rods
Lightened flywheel (machined down standard)
1641 B&P's
Standard twin port heads (with 3 angled valve seats)
Single up-rated valve springs
1.25.1 ratio rockers
Engle 120 cam
Melling oil pump with external oil cooler
Bosh 009 dizzy
Single quiet pack with J pipes
Single Dellorto twin 40

That gave around 90bhp. It was easy to liberate a few more bhp out of it with a balanced bottom end a better exhaust.
