Earlier I was running a 21-4C which after while was so low on compression that it kept going rich and dying all the time. So I swapped it out for a newer one which has very good compression.
However, the old spent one seemed to produce a lot more power. Low down and high speed as well, what could this be down to?
Would it be that the one which had spent all it's compression would be able to rev more? It seems strange to me that the newer engine is so much more of a slouch.

did it seem to produce more power even at the end of its life??? maybe try to clean the pipe or try a new pipe and header on it.. when i say clean i meant the inside not the outside.. both pipe and header...

and how much fuel do you have through it

they are always fastest before they go bad

A true comparison between 2 engines that are exactly the same would be most accurate when compression is the same as well.

Also don't forget that the p4c, p4c team, and p4 btt are different engines.

I have a question, I was thinking about getting a Bonito in the spring to put in my RC8T. The last engine I had in it was a OS 21 XZB stock. It ran real well with the OS, but I was looking for a little more power. How does the Bonito match up stock for stock with the OS? Will It have more bottom torque? How does the top end compare? There is a big price difference between the two engines. I guess the main question is will I see a big difference in performance between the 2 engines?

Thanks.

What is a Beat Nova Rossi?? http://www.neobuggy.net/modules/news/

Lee running a Beat Nova Rossi I like what he said about not having that on off feel. Anyone have any info on this motor? Is it a 3 port 4 port 5 port?

ok looking for a matchup between these two engines bonito/roma in a mbx6tr
probably be using a 9856/4001 or 21 pipeset
cheers

9886/41001...even 9853/41001 is OK..............The 41021 tones the power and RPM down over the 41001

I was trying to figure out the same thing. 4 port for sure. Modded by someone called BEAT? Look at the sticker on the wing.

Sorry Neil I should of worded that a bit better
I was after a matchup between the Roma and bonito
Running on a mbx6tr how do they compare with power through the range and run time I am trying to make a division, I already have the Roma but looking at a bonito for 2013 or maybe stick with another Roma
Cheers

Maybe he was chasing grip changing from the Bonito to the BTT maybe...

It appears to Say B4 Plus on the head

kinda funny how EVERY novarossi engine at worlds is using a 41021 or 41029 header isnt it?
