How about OS? I have purchased a bunch of P7s recently, for my nova based engines...

I was told the P7 acts like a R6 and the P8 can be compared with a R7.

And yes, the do work very well.

Have you bought any recently Roelof? I know they used to be great but I have heard rumors that they have gone the way of Nova with the cheaper element.

No, we just have a small batch from last year.

os plugs
 

Im not sure with os plugs,myself and a couple of mates had some issues with them recently dropping there elements so we changed to rb plugs had problem since.:nod:

Hi guys, i have a N12t1 and the recommended plug is the c5tf which is the short plug, can anyone tell me whats the RB equivalent or maybe another brand equivalent plug?

thanks.

OS plugs have become my favorite, but I have also heard good things about the O'Donnell plugs (by the way if they are made by Merlin, that is the same company that makes plugs on a regular basis for Traxxas.)

On a side note, has anyone used OS plugs with Picco based engines?

OS turbo plugs have a different taper than Nova Rossi/RB turbo plugs. Installing OS turbo plugs in a cylinder head designed for NR/RB pulgs will create sealing problems. Merlin has a plug that is designed to both applications.

This is true but oddly enough, it mainly seems to be a problem the other way around. I have found that most any plug will seal fine in a Nova motor but Nova plugs WILL leak in an OS. It's strange but true.

Also, I have had really good luck with Picco plugs in the past but haven't tried them in many years.

Can you tell me which turbo plugs will fit into which engines? (lost my confidence with Novarossi plugs and trying to find something new..)

Can i put GRP plugs to Novarossi
Can i put Novarossi plugs to GRP
Can i put Sirio plugs to Novarossi
Can i put Sirio plugs to GRP

Thanks,

EFRA 2503 exhaust
 

Hello all,
What is the story behind the newly introduced 2503? How is it compared with the other nova exahusts?
Thanks in advance

I will do you one better, does anyone have a link to a chart, or information about where the pipes for on-road, 2015, 2018, etc, make power? Its been quite awhile since I have raced, the only pipe I am familiar with is an 086 series. :eek:

NOVAROSSI PLUS 123CT
 

JUST WONDERING IF ANYONE HAS RUNTIME ISSUES WITH THIS MOTOR ?IM RUNNING THIS MOTOR WITH THE 2652 NOVA PIPE ANY INFO ON HOW I CAN GET THAT EXTRA MILAGE WOULD HELP.............BY THE WAY I MUST SAY THAT I LOVE THIS MOTOR ,IT SCREAMED BY A COUPLE OF MODIFIED HIGH END POWER PLANTS WITH NO PROBLEM :sneaky:AND THIS ONE IS STOCK !!!!!!!!!!

If it's still legal where you race, stick with the 086 or 9886. If not, 2015 for mileage, 2052 for a bit more top but a bit less mileage. Also, Sirio 2013 is a good all around pipe with good mileage.
