It's great to hear from you again Steve, I knew you would be back. So, what's the new ride? Knowing you it will be something exotic. I have been looking into the Serpent 960. I got a chance to see and examine one a while back, and it is awesome. Steve call me. 7703789669.

I think the Lakeland track has close for the time being. At least that's whats on the web site.

Please, let me know if I'm wrong on this as I was planning to make a couple of races there myself.

From what I understand from the Florida crew is that it is closed until further notice.

The OS TZ is a very reliable and easy to tune engine. The TZ is not as fast as the modified Novarossi or Sirio Evo3, but it's close... and almost $100 cheaper. The TZ has a very linear powerband with great punch off the line, and great midrange. The TZ just does not seem as happy to rev as the Novarossi's, and especially the Sirio.

Grinder how is your modded version of the OS TZ compared to your modded novas and evo3?

thanks jason!

Hey Uriah, will you be modding the N12LL3 long stroke Novarossi engine?

p.s. on your website, yo describe the EVO 3 Sirio as "a missile"? Do they also blow up like one or do they hold up OK?

p.s.s Faster than the Awesome Murman X12??

Hi. The modified TZ is almost as fast as the Nova and Sirio, but not quite. Seems to lack the top speed of the Italian engines.
Rody, about the long stroke. I can't seem to get the power that I want out of the long stroke. I have been testing the engine for a few months now, and the short stroke (LS) is faster on the track than the long stroke, I tested stock and modified with the same results (short stroke faster). I tested the Rex LR3 which is the same as the N12LL3. The engine is supposed to have more "bottom end", but I can't seem to find it. The engine is not slow by any means, just not modified LS fast or Evo3 fast. I will say that the long stroke powerband feels more linear than the shorter stroke engine.

Grinder,
When you ran the Mega ZX 12 a while back did it have good bottom end power? Second thing how did you shim it for 30%? I have all three shims in mine right now.

Uriah,

It seems that most of your work is around .12 engines (and they are ballistic). How much experience do you have with .21 onroads?

Thanks,

John

look

LOL looking for more power

The Mega ZX12 has great bottom end power, the most I have seen from a stock engine. The problem I had was it was almost impossible to keep it tuned, and it blew a rod within 2 gallons ( I hear this was longer than ususal). I never checked the head clearance, but I added one .10 mm shim to the engine before I ran it, seemed to work fine. The .21 Mega is slow and fragile.
Jrabbito I also modify .21 engines. I've done a few.

Look, I got the power.
