i would also go for the nova 2630 pipe. as for the manifold, it depends on the type of track you are running. nova has 3 different manifold length to suit your needs. the nova conical manifold comes in 5 fins, 6 fins, 7 fins. hope this helps

The Novarossi 2630 The 5 fin header is good, but I prefer the 6 fin with the short stroke engines, like the LS3, and NSR. I feel the medium (6fin) gives more punch out of the corner for the short stroke engine. I also like the 6 fin with the +12 long stroke. It also depends on the track.

Hi. I do have pictures. No I will not post them. I know that there are some others out there that are deliberately trying to copy my +12 design, and sell it as their own.
I will not mention any names until I have to.

Grinder: Which manifold length do you recommend as a starting point for the nova 12+3 sct? Any comments on this new engine? Thanks

I start with the medium most of the time. Maybe the short. I rarely use the long, especially with the +12/2630. I have not seen the engine in person yet. Please post some feedback when you test. The engine has a larger diameter crankshaft. 11.9mm instead of 11.5mm.

Will follow your advice. Placed an order for the nova 6 fin conical manifold with 2630 pipe Would you happen to know what benefits does one get using a larger diameter crankshaft of 11.9mm as compared to the 11.5mm? Thanks

Default Which One

I've decided I'm going to treat myself to a Murnan engine with full ceramic bearings in the New Year but can't decide out of the following and wonder if anyone can advise?

OS TZ 12 3 Port - I fancy this because it's a little different to the norm here in the UK, but wonder how it stacks up against the modified Nova's and Sirio's in terms of performance and reliability.

Novarossi Plus 12-3 CT - I've always liked Nova's for their performance and reliability but they're not always the easiest to tune.

Sirio Evo III STi - I know some guys have had issues with the crankshaft on the standard engines, can only assume this would be worse on a modified engine, I believe also that the AAC construction yields more power than ABC but it not as long lasting.

Any news yet on a modified RB Matrix R?

Howdy Bro ... did you realise that your signature below takes one to the Oral-B website?

By the way, Murnan engine rocks ... no matter the model.

Hi Sow,

Yeah, I'm not sure what has happened to the link it all looks ok and if you type the address in it goes straight to my site. Unfortunately I haven't done anything to it for a long time, too bloody busy digging the garden and building walls which has kept me off the track as well. Still got loads to do but must make time for some more racing next season, hence the interest in the Murnan engines and hopefully a new chassis, possibly MTX4.

All the best mate and hopefully meet up at Brooklands and Aldershot,

Diesel
