Good luck mike at the coming worlds! still waiting the info for dealership!

What's the difference when I use a fuel with less oil %?
I´ve used Byron Race 1600 12% oil, but my dealer doesnt have it anymore, so I want to use Byron Pro Drive 1600 that have 9% or 10% oil

One more question, I bought a OS TZ 3 port can I use a fuel with 20% nitro without change the shims?

Go check the O.S. tz thread in the Nitro motors forum for more info, but my TZ works fine with 30% on stock shimming, most other people are using the stock shimming with up to 30%, I would shim it up with higher than 30 % or if your atmosphere or altitude conditions warrant it...

The 9% oil will gain fuel mileage and will give you a little more bottom end.

You should not have to change any shims for 20% fuel.

Ffejdat, what atmoshpere or altitude conditions are you refering to, could you or someone elaborate please, thanks in advance

whats up, sandra. i see you guys were at the GLC and whit was in D main. pretty good stuff. you coming to the 1/8th nats?

Hey Joe we were at the GLC and we had a great time,and yes we will be at the Nats but I won't be running though,look forward to seeing you again on your on turf. I'm sure Chris will be hitting you up for a setup :nod:

Mugen Fuel = Byrons.

Byrons make excellent fuel, my favorite actually.

how come you are not running??? it will be a fun race.

Well I will have just had the baby, soooo I will be tending to him :nod:

Even Superman think twice to use 40% nitro for .12 engine :D
I think it's too hot ( unless you want to throw the engine after the race ).

ahhhhhh, makes sense. to tell you the truth, i dont think i am going to be running as well. my local track closed down, so i have no where to even run my mrx4 now. it is still brand new never driven. so i probably am going to sell it on ebay for $500 or so. we will see.

Hey Joe this Chris, heard about the track, sorry to hear that, but come on out and run with your boy.
