Why do you recommend not using Picco plugs with the Evo3?

They failed on me a few time's now, that's why.
If your engine reaches a temperature above 120C/250F, a Picco plug gets damaged, with engine flame outs being the anoying result. With some racers the wire even broke and sometime partly fell in the engine, and that is exactly something you don't want to happen!....

Then I decided to switch to GRP plugs, which in my country are also way cheaper then Picco plugs, and all problems were solved....
I jet have to try IDM/Sirio plugs, because they seem to be even better then GRP (I've been told)

Picco makes great engines, but plugs...

depending in which car you will put the engine, you have 90 degrees or even 180 degrees manifolds.
But these 180 degrees manifold are not standard for racing type of engines....

you say that grp plugs fit on picco engines, and some people say that is also fits on nova based engines, so why nova and picco plugs dont fit on each other?

Picco plugs will also fit Nova engines, but Nova plugs only fit Nova (based) engines.

I will try to explain.

The thread on a Nova engine goes deeper into the headbutton then on Sirio/Picco/GRP engines.
Therefor also the thread on a Nova plug goes further into the direction of the conical part.

Which means that you can't use a Nova plug in a Sirio/Picco/GRP, because the thread in the head button isn't deep enough, but using a Sirio/Picco/GRP plug in a Nova (based) engine is possible, because there is still some thread left....

And as I expected, very similar if not exactly the same as the Mega engines.... maybe a bit more top end....

Break in is easy, after pre-heating just 2 tanks very rich WOT on the starter box, cool down (10-15 Minutes), another 2 tank WOT on the starter box, cool down again, lean the engine until the car will move, and each 2 minutes go for refueling and lean the engine 1-2 hours on the HSN. within 1 Liter i was at racing speed.
105 Km/h, http://www.mylaps.com/practice/showL...ponder=6839132

calculated rpm then was 41.500....

In the beginning I drove the engine with Picco 3031 exhaust and conical manifold, at the end I swapped to 2033 exhaust pipe....

And how did you find both pipes? I've only tried the 3031 so I can't compare..

The 3031 Picco pipe was made due to new EFRA rules on the 3-chamber pipes in 2008, in which pipes where changed, and conical manifold where prohibited.
You probable know that there where some problems with the introduction of these new exhausts (Sirio even didn't make one for there engines...) which "forced" EFRA to change to rules and allow some older pipes again for the racing season 2009 we are about to start with.
(Just some background information, because this is a ROAR forum... )

But to answer your question.
I drove both pipes with the conical manifold which came with the 2033 exhaust, the 3031 pipe normally comes with a non conical manifold.

With the 2033 you have noticable more mid power, and slightly more top end.
I still need to try the engine with the 2052 exhaust, but because the Mega DSII engines really loved this pipe, I think this Picco will also like it...
Coming weekend, if the weather allows me, I will try this...
