Looking at both of these, does anyone have any real world testing or experience with these?

Thanks

I run the Novarossi and my team mate runs the OS and let me tell you that we are equal power wise all over the circuit (acceleration and top end). The only difference that I can tell is that I get a little more fuel milage with the Novarossi than the OS. Probably around 20 seconds and so about a lap at our track and in Qualifying that's made the difference in the past. He's run out of fuel on the last lap before when the track is nice and grippy and the temp is high.

My Opinion the two engines are good.
I think you should choose the one that has the most durability ...
To monetize your money.

Again there is no difference in durability between the engines . Both are arguably the best on the market.

I would bet that the OS engine pipes are significantly more expensive to replace (at least in the USA).

Yes that's true the OS pipes are mightily expensive!! So I guess that's another thing to consider if you crash alot

Its not about crashing, its more about getting hit...

In this case buy the cheapest and the best in the fuel consumption.
Since in terms of durability are equal.

Thanks for the opinions, guys. Looks as if the OS is about 25 grams lighter. That's a plus. As far as fuel consumption, there has to be many factors involved there. Drag on chassis and gears will make a big difference there.

Then there's the color, the OS appearance wins all day long in my book.

So which engine did you choose?
Then put videos and photos of the engine to see.

We dont see T1202 on our track yet, but the T1201 still keeps up with the MitoWC. PS. our track is a 11~12sec track.

Guys , i dont know why all are saying about the fuel mileage , here in mexico i Have some OS T1201 MAG tuned with OS 1070SC Pipe and i can get 6+ Minutes , and the Novarossi with 2660 médium header i ant get 6 minutes , we run at 2300 over sea level , and i use 40% nitro and #7 PLUG , maybe im not running that strong like you and it is for i can get that time , my temps are OS 140 C and Novarossi 145 C

Regards

Good idea.

GOOD info.

Good info. I have both belt and driveshaft cars, mileage will vary from my Tm G4 to NTC3.
