Hi,

.21 engine tuners, who should I be talking to!

I'm aware of the off-the-shelf tuners, JP, MAX, M. Rossi etc.

Has anybody run, say a JP RX21-Roo & then a fully modded RX21-Roo, notice any difference?


Thanks in advance for the help.

I've modified mine own R1WC and found that modified engines probably has more mid-rpms power and some more high-end rpms, very fine for large tracks we have there, but sometimes, fuel mileage is seriously affected making barely 5:20 and gone completely dry on some tracks who abuse from mid to high rpms with the 9mm throat. I go for a 8 or 8.5mm throat and found some precious time.

Making HP on those beasts is 'relatively' easy, but think that sometimes HP isn't the only into the equation. Fuel mileage is another and how the power goes to the ground and at which rpms.

You can always look a little closer to home. Send me an email.

Let me know when the next big race is on at St. Annes. Cant wait to get back down.

Uriah Murnan has done some Sirio 21's that were awesome. He goes by "Grinder" and has his own "Murnan Modified Engines" thread.
