The rolling ive ran
41005/9901
41021/9901
41021/2096
41033/9901
41033/2096
Hipex medium header and 2108 pipe.
41033/9901 was the fastest but came on really hard at the lower end of midrange and caused some wheeelspin.
Imo the hipex pipe "runs" the best for me but it loses that novarossi sound.Id like to try the 2135 but its winter here.

how was the 41021-2096 combo?? thinking that is what he will try in truggy first.. jeremy

it felt too corked up on the top end in truggy for me, it runs pretty damn good in buggy with the 41021/2096

Gotcha.. ya we have a few long straightaways that engines need their legs

Try the 41001 or 41005 manifolds. They give the engines more sanp and a better top end. The long curved 41021 smooth moast engies out.

Has anyone tried the 2135? I like the sound of the pipe, but to me it does not like the engine wind out. Its good for fuel mileage but the power seems down some to me. Tried with 41031 and 41021 header

I like 41001 and 9886 pipe for .21 truggy.

You have sales on Novarossi Engines?
PM me details plz wichitafc98l

i'm running a keep off 4 in my hb buggy with a 9901 and 41001 and I feel it could use more power. is this the right combo for this motor. I have some other pipes I could try. werks 2013 and 2058, dyn 053 and 086, also a 9886. any suggestions?

Not an expert on this Nova, but something we did this past weekend with our bonitos was went up to a larger opening venturi/restrictor and that really woke up the motor.

On my Rolling I am running a 9853/41032. This combination is very drivable and also very fast. I have also previously run 41021/9853 and 41021/9901 but neither of these combinations produced the power and top end that I was looking for.

as nova fans,,
why not many Top IFMAR drivers using novarossi,?
just wondering

They've lowerd the price of their engines, so there is probably not as much money floating around.
maybe Novarossi have turned to proven history to try and continue selling engines, alot of p5's around.

Only Mcbride using Novarossi?
