Hey I know its nice to have the hottest motor on the planet, but if you cant handle a std MT12 you are making a mistake. I know it took half a season get use to my upgrade from that to the RB 5port turbo. The difference in power made suspension and drivetrain changes necessary. I think foams would make that a little easier to handle.

the engine was fresh (the car was only 1 race meeting old too)

so i think it has potential, probably a better question is can you drive as well as the bloke with the JP? that will probably make more difference than the 0.0?hp difference.

one thing we noted was the engine had heaps of bottom end at the start of the final, but after the 2nd pit stop it lost a little - not sure why - still quick though and i think you will find they are a bit cheaper than a JP

bottom end power is everything - as long as you can put it to the ground.

Mad Max I agree. But there are alot of uses for a dyno. For example you can find where your peak power range is and you can use that to adjust your gearing. You can even tell if the plug you are using is good for the Nitro that you are using. If you are a rookie yes the only reason most would have a dyno is to see how as the most hp, but for a serious racer it can be a very useful tool for tuning your car. I can wait to see if Fantom comes out with one because I will own it.

I have had dynos in the past (for electric) and in all honesty the were best at matching motors more than any thing else. Each time you run them you got different information. Now don't get me wrong you could plan some gear ratios with them but the primary benefit (in stock class) was finding out which of the motors may be the strongest or if you mis-setup a motor.

As for dynoing a gas motor It takes more time to yank the motor out than electric. Most sportsman or even experts come to the track with one motor and a spare(if your primary blows up), if you have the money for a spare.

If I need to dyno a nitro motor, I would rather go out and pick up a new one, modified or unmodifed, first. The numbers relationship on tune, plug etc. has to be done at the time of the race given the atmospheric conditions. A dyno will run as much as two of those hot JP jobs.

I'd put my money on a tire truer and a ton of foam.

Opinions vary. I have found more uses than that. But for nitro I think that it would be a beny for the guys who mod there own engines.

I don't admit to modifying my motors, but I'm not saying I don't. If anything, I find more out at the track with extra plugs and gears than I would at home with a dyno.

Besides if you are moding your own motors you need to be really sure about what you can or should modify. plus the need for extra parts if you screw up. I can take a box stock mt 12 re and be one of the leaders all day without having to mess with the motor. fresh plugs good tune and clutch tweak and gears, I think that is all you need.

I am not disagreeing with you. Time at the track can be the best tuning devise out there, but I still think in would be cool to at least use one just to see if what the manufacturer is saying is true.

Not really. That would be like trusting a car salesman.

Computers are a whole different ballpark. I used to be a car salesman. It was the crappiest job I ever had.
