Hi Brent,

we have raised the sleeve on a Torque by 0.1 and 0.2 mm in order to gain top end.
We did, but it hurt the fuel consumption.
I rather gear the Piccos a bit longer than Novas to get the same top speed.
What also helped to gain some revs w/o hurting fuel consumption is using the Nova medium conical header with the Picco 2033 pipe.

My son is still running with a pretty smooth gas finger (will probably be spoiled soon) and he makes 5 minutes with the Torque, doing the same lap times as other people who run NR Flash and only make 3:30.

This has given us the edge in several races this year and I will try to conserv that advantage as long as possible.

Once he is going completely "point & shoot" and won't make the 5 min anymore, I will start modding the Torque towards top end...

What are your thoughts of this Picco TQ .21 compared to the 35Plus21 engines? I am a drag racer and fuel consumption is not a concern of mine rather just having an engine with TONS of bottom end grunt and mid range. My current Kangaroo has been 90.2 MPH from a dead stop up to 132' pass which is ballistic for that short of a distance.

Thanks to all for your input.

It would be interesting to see which answer Novarossi has if that change will happen. If they are not on time a huge shift will happen....

For the guys outside Europe wanting to know where we going to talk about:

Also in the main agenda there are some proposals about the exhaust homologation:

Whenever you change timing either sleeve or crank there is a give and get. When you raise the sleeve timing you will hurt some of the bottom end. My opinion the picco based engines all have alot of torque to them by there nature so loosing some may not effect it quite the same way another engine would be effected. Of course depending on how high we lift the sleeve.

Wow, 90+MPH in 132'!!! That Kangaroo is a great engine. Congrats!

We still run 5 minute qualifiers here in the USA and Novarossi engines dominated the ROAR Nationals last month. The current Nova engines are actually very efficient and can be set up to run 5 minutes quite easily.

Understood. Was just wondering if anyone had actually gotten results from raising the sleeve for the higher timing, IF it hurt some bottom end at all.

Hey cool! You wanna share how it's done?

I am sure the NR racers over here would really appreciate it.

Robert Pietsch's mechanic is always re-fuelling at 3:30 minutes when he runs 8th scale. :-)

Probably it has to do with the type/size of the Europian circuits.

Hi Brent, I know about the timing. Roelof has posted engine timing a bit further down. where the Torque is listed with 30 -70 = 220° crank timing, which looked strange, especially in light of the awesome fuel consumption of these engines.
So I measured mine, and the are different.

I love the Torques, aside from some bearing problems we had early in the year.
It seems that it was only one of the very early batches (January -February) because later engines didn't have that problem.

The thing you need to get used to is the very low compression these engines seem to have when they are cold.
Some guys wanted to trash them, despite they were running awesome.
Just old Nova habits :nod:

The Torque has a different piston material that seems to expand when the engine gets to operating temps and then works great.
Very easy to break in and easy on the rods.
