125 Engines

[Admin]

shamelessly taken from another forum ..for your info !

The Germans did a very thorough TAG engine test, with some of their best karters on many different tracks.

They took two samples of each engine to the dyno.
The grey bar is the manufacturer's claims.
They took the more powerful of the two to the track for the comparison testing.
The test lasted 5 days.
Seven drivers drove one after the other the karts, two times each, in ten minute sessions.
The best time of each driver was added to those of the other and the final number was divided by seven.
In the second session the tires were changed so each driver drove with one set of used and one set of new tires.
They all used the same brand and type of tire, not necessarily the same at every track.
The telemetry used was from AIM (Mychron 4) and each driver wore a Mytach on his wrist.
The results form various tracks where as follows:

The slowest track of all with plenty of slow corners.

Has anyone got the new model PRD Fireball, apparently the parts are just as cheap as a kt. What do you reckon is the fireball a good motor. My mates getting one so I will wait and see how his goes before I look further into it was just wanting to know if anyone has got the new model and is racing with it.

Thanks William
