i own both and i would say yes, the new one is even slightly better.
throttle response is super clear like it a ton!

In my experience long needle carbs will get better mileage and deliver a more balanced throttle response.

Running original FX in truggy and the K5 in buggy. I got nothing but compliments on how strong both sounded all weekend. Running P3 plug currently, going to try P4 next weekend.
Absolute beast with the Werks 2058.

Comparing to the Protek Samurai and Novarossi 4 Port. Found my new favorite!
Cheers

first race done, finished 7th in the a-main, was 3rd after quals.
k5 was superrich whole weekend, now 24 tanks done and still mechanical pinch there.
switched to p4 after tank 14.
this engine is money, no questions, tunes like a dream, too much power for this rutted blown track lol

What insert/head shim/manifold+pipe is everybody using to get +10min of runtime?

I run mine with a 6mm insert, 0.4mm shims and 2100 pipe + small medium radius header, but I can't make 10 minutes.
I also have the 2108 pipe with medium radios header.

Its all about throttle control. A Danish team driver bearly gets 7:30, other +/- 9, I get 9:30 - 10.45 and RobinCH +11 at Bittydesign Contest.
Something that will help mileage a little: You don't need 0.4 mm headshims. Use the stock 0.5. X4 or OS P5 plug. For me, I get identical runtimes wether I run 6mm Mizer venturi or stock 7 mm FX venturi.

I haven't run my new engine, but the old one had 0.3mm shims by default.
I'm running OS P4 plugs. Do you also run a P5 when it's colder than 20C?

I'm not super smooth, but not aggressive either.

I tried both pipes and while I like the 2100 the most, I think I'm getting more runtime with the 2108.

Add the head shim to .50mm that will help some with the mileage. You won't notice it anywhere else. Also I would be willing to bet your LSN is 3/4 of a turn too rich.

Oh, the old. As Frank wrote 0.5 is fine with 30% nitro? I run 0.3 in my +20 liter old pre production engine (25% nitro). Started with 0.7, then 0.4 and now 0.3
Did run P5 last year at one race. Temp 10-17C. We have had a very cold spring this year (5-15C) so no P5 yet :-)

So 0.5mm is fine with 25% on the new one? I bought one a month ago, but I still need to fine some time to break it in.

My V2 from last year is about 35l old. Just pinched it around 20-22l and it's still going strong :-)
