Default Ninja .28's

Anyone here have much experience with ninja .28 engines.

I’m thinking of getting one for my Truggy to replace the .21 it’s got.

But am just wanting to know what sorta run time these engines get compared to the .21 and also how the speed and torque they have compares to the .21.

Getting 8 minutes run time in a Mugen, but with a lot more bottm end than the .21. Top end close to the same. If track is large, then you can gear up to tame it down plus get better fuel economy.

I highly doubt that maybe 5-6mins maybe!!!

I don't understand why ppl think they need a .28 in their truggies... the .21 engines are fine and have way better fuel consumption. The .28 just add to the costs of fuel and wheel spin which makes you SLOWER not faster... I have never use a .28, (on the track) they are over rated in my opinion, unless you are a busher and don't care for handling (drifting) or wheel spin. with the right tunning/gearing and pipe/header selection the .21 will always out power the .28 on any track...

well I can personaly vouch for the Ninja 28...... there is nobody lying when they say it will get 8 minutes run time, its got excelent mileage for a .28 . As well the powerband of the Ninja 28 is buttery smooth...with the Ninja 2053 FLS pipe the motor works extremely well on the track.. It feels like a very strong .21 , the powerband is smooth and linear, with an exceptional top RPM...... The Ninja 28 is a new breed of .28 and shouldnt be judged based off older 28 from the past.....

yeh alright thanks for all the info.

still not sure what to do tho, the .21 i got is fast but im just not sure how the .28 will go.

from what you guys say it should be awsome. but my only experience with a .28 has been the nosram one. which all it wanted to do was wheel spin.

i think i might just go for it and get the ninja .28. if i dont like it, well to bad for me

I have a Ninja .28 in my MBX5T and with the stock gearing it is INSANE. It'll get easily over 8 minutes. With the stock gearing it'll wheelie like mad and spin all 4 tires down the straight away. I was 2 seconds a lap slower than with my .21 Ninja. I run the MSR1005 pipe and header on both motors. This weekend I am going to try the 6.5mm carb restrictor in it as well as a 14T clutch bell. I also have a 15T clutch bell if I need it. I think if I can tame it down the lap times would improve. I'll also time it to see exactly how much run time I get out of it. I run the NInja #5 plug, stock deck height and 30% Maxy's fuel.

Best regards,
