The stock 35+21 has more top end, and less bottom end than the Cordoba engine. Modified they perform the same.
The Flash has more midrange, and more peak HP than the 35+21, and Cordoba. The Flash has slightly less torque than the 35+21, but more peak HP.
The best bang for the $ is the Picco P9R, and the 35+21. The Picco is cheaper, but it will not last like the Novarossi. The Novarossi is also easier to tune when near the performance limit.

Region 1 july11-12 in Cahaplin, CT
I would like to thank Murnan Mods for providing the awsome power plant for the Region 1 race. Murnan's RBR3 powered my sedan to a 5th place qualification in the A-main and a 2nd palce finish after a long 45 minute A-main. Very consistant and smooth powerband with a temp of 245 degrees at the end of the race. Not once did I have any motor issues during the race.

Grinder,
Hey, after rumaging through some older stuff, I found an original P5 p/s. I was wondering if these could be used and/or modified to fit any current Novarossi platforms. I do have a JP Ro3 that I was hoping it might fit. Anyways, any help would be appreciated.

ConRod Question
Grinder,
I have a NR RX21 Kangaroo and a Murnan Modified NR 35+21. Both take the R7 conrod according to the NR spec sheets. My question is, are there any modifications to the MM NR 35+21 R7 conrod or are they still interchangeable?
Thanks in advance for your feedback,
Roger

Murnan Nova Rossi S21WCS09 motor
I received my new S21 from Uriah last week. I carefully broke it in on friday.
went to the track on Sunday ( the newly resurfaced Gulf Coast Raceway, WOW!!!).
This engine is amazing! Gobs of bottom end! even more bottom than my Murnan Flash 21. Does'nt have the top end the Flash does, but at this track
bottom and mid-range are more important. Good motor for $500.00!

Tech Regular
Just wanted to thank Uriah for the crazy HP this weekend at the GLC. This was my first race with the Murnan RB and it worked great all weekend. No problems with runtime on the Toledo track which always needs good mileage. Unfortunately the main didnt go as well as qualifying but we learned a lot this weekend and are looking forward to the nats at the end of the month.
