thats been on nova site for a while merdith , there might be a link in the tuning bible thread even , great chart for sure :nod: but i can tell ya right now you will have a hard time making a c7tgc run easily in 77° weather ;)

they work great with lowered head clearance above 110° unless you are running on road then you jump into the H plugs which are much colder c5tgh c6tgh c7tgh c8tgh c9tgh

True
 

I can certainly understand. I remember back in the day when I tried cold plugs just to see what happenes it ran pretty bad. It wouldn't hurt to have a couple in the pit box for those hot Texas days. It does get above 100 degrees here in the summer...

I really just forgot the c7tgc's existed. I tried the Odonnell 99t's with great success recently. the coil stays nice and consistent for 3 race days. Not bad. although it's really a cooler medium plug...the c7 is pretty cold, is that correct?

For all those curious the roma has landed in the us!

;)

How much are they?

clicky :D

Wow its cheaper then the bonito. Wouldn't have thought that.

the description reads its the fastest , its been run and tested already, damm thats fassst:deathstar as far as pricing, yes it is pretty cheap, but it also might be the standard model w/no tuning at all, ceramics etc etc..dont worry we will have a 500plus version to buy real soon...lol... I WANT ONE!!! i just was pulling the trigger on a bonito fully done up, guess i can always make it my spare

I would like to see what kind of fuel mileage it gets on different pipes and what not.

For now I'll stick to a .21 :sneaky:

Drake made pitstops at 12 min. during the Psycho Nitro Blast a few weeks ago with that engine. Stock? Don't know :)

;)

awesome , good to hear

i watched Billy's at the nitro challenge and knew it was not a bonito ;)

Hi guys im probley asking the wrong questern here as you are all nova doods

but im second guessing my choice to run nova engines this year i mean im stoked about fuel economy however geting the tune balanced and both my btta seem to just not have that oomph if you guys get my drift

Post your whole setup

If you are trying to use the plus4 in truggy , you will feel there is not much "oomph" or punch

dont 2nd guess novarossi bro that would be a big mistake..i ran the plus 4 <first version> modded by houston, and i have to say it idled all day, held a perfect tune, power for miles,pitted at 10 min with PLENTY i mean PLENTY in tank, probably one of the most "usable " powered novarossi's i ever ran!!, yes post your pipe selection/plug/fuel/ and did you break it in, buy it 2nd hand...novarossi's are the ferrari of nitro, and they make more models than the plus 4, you can have as much power as your car/truggy can handle, and than some.....

A P5 will cure that ailment.:)
