I'm gonna help a brother out.




I'm gonna help a brother dig deeper into his pockets......LOL!

i dont think anyone in this hobby needs help doing that!!:hat:

Inferno, when might we make that exchange?

hope'in by sunday if eveything go's good!!!!

I dug deep to the depths of my pockets and all I found was lint.
Tipp, will you take a pocket full of lint for that fuel?

As long as there is green backs folded in the middle of it......sure!

There is some thing green, but I can't tell what it is.

MMP still acting up! called castle today and told them what it was doing and thomas said he would send me a new one! good customer support right there!!!!!!!!!!

Nice to here Inferno :) wanna bring that thing down to PVG for Bragging Rights ?

was planning on it untill scott told me the date, ill be in florida:cry::):drunk::confused:

March 5th, would love to go, but don't know. I really want to go down to the Washtenaw race this weekend but started the tear down on the truggy tonight and starting my parts list, so far new bearing kit,just ordered a new pipe, already have the new os xz25 motor, new fuel tank, need new front diff housing and that's just for starters so maybe I should save the trips for this summers nitro series.

Have I mentioned to anyone that I can't wait till summer gets here, I am so ready for some 8th scale racing and stop playing with the little 10th scale toys.......

Tipp, you going to da u p this weekend or staying around here.

Don't know yet, what you gonna do?

Tipp, let me know if you guys are going to do a group brake in on the new motors, would like to join in if possible?

doesent sound like your ready for this summer....LOL.

Don't know yet, what you gonna do?

Probably. Just try to hook up with people to even up on some past due bills.

Wow man, never realized you had to break in a brushless motor! How many packs do you have to run through it? Lol

sent you pm brad!

No brushless here. Well not in 1/8 scale anyway.

jbod, your definitely invited to the break in party, when it happens.

Well thank you. We are talking about starting nitro motors right? LOL

Well thank you. We are talking about starting nitro motors right? LOL

guess i better order some fuel....LOL, any body that needs some better let me know soon!!!!

yep, nitro baby........

Sorry, did'nt mean to call you baby.....LOL! Just got a little excited.

Does ICE have a new mill this year? I heard that break in lasted about three minutes for him last year, before he was doing donuts in the parking lot. LOL.

Inferno, you ever run a GO MOTOR on 20% before? If so, how does it run?

Where all in trouble, he bought my os .28, so no break in for him this year just go fast.......

Man, you've seen inferno race, he doesn't know what 20% is, its WFO or nothing!

Inferno, you ever run a GO MOTOR on 20% before? If so, how does it run?

they all run on any fuel, just have to adjust head shimming accordingly

LMAO. RIGHT ON!!!!

Well talk to me brother, you know I am running 20%. what do I need to do? is the .25 set for 20% or 30%?

Most motors, 20% no shim, 30% one shim.....

What does head shimming do? Less shim lower nitro content? More shim higher nitro content?

Most motors, 20% no shim, 30% one shim.....

Thanks Tipp that helps. I read some where to add shim on break in,but remove after. To help make break in easier on new motor.

Adding head shims reduces compression, taking them away adds compression, the 30% nitro is more volatile under compression so you may have to add shims to reduce combustion pressure to get a consistante burn without pre-ignition, essentially spark knock where the fuel compresses before top dead center, very hard on the motor and poor performance, glow plugs can do a similar task but not as drastic as the head shims because nitro does'nt burn well but ignites very strongly under pressure.

Sorry a little long winded but I've spend hundreds of hours researching this toppic, litterally.

So basically with 20% I should not need shims?

Very well said.

JJ, how's them hpi products doing for ya? LOL.

Should be good with no shims and 20% nitro, I'd play with glow plugs a little. A hotter plug will give you better idle but rob some top end from the motor. A colder plug will be harder to keep idling, but will give you max performance on the top end. One way to compensate for the idle, is to use a steel flywheel, it works two fold, one-it will smooth out your idle so you can use a colder plug and it still idles good and two it smooths out the power curve, giving you a smoother power.

Then there is the clutch set-up, which can also effect how you tune your motor.......but we'll save that one for another time.......LOL!

Maybe I should just pay you to set my motor up for optimum performance. You have time you just started on your truggy.

Can't do that. You need to learn how to tune for yourself, as does everyone racing nitro. The great thing is, once you get the basics figured out the day to day tuning is minimal adjustment. Atleast with the O.S. motors, I don't know about those finikey GO motors.....LOL!

I can make any combustion motor run! Fine tuning is my default, but I slowly learn more and more form guys like your self everyday. It's nice to be able to pull so much knowledge and information form people in the NMRCC group. This is why I stay with this group! Well that and all the fun BS.

But you still owe me money for the fuel......LOl!

flywheel and glow plug have nothing in commen! cold day....run a hot plug, hot day run a medium plug, as for shimming, 20% requires 1 aluminum shim, 30% requires a aluminum shim and 1 copper shim, depending on atmosphere presure, lets say in colorado you would need a aluminum shim and 2 copper and run 40% nitro to make up for differnt air pressure, here you would need 30%, 1 aluminum shim and 1 copper to get same power as the above, glow plug not really in the mix as far as fuel % goes, just shimming and atmosphere. the GO ENGINES run best on 97t odonnel plugs or on a cold day 77t odonnel plug.

The flywheel and glow plug are not the same but they can both effect idle, that was my point. the heavier steel flywheel carries the piston around and makes for a better idle and because of its weight smooths out the power curve. The glow plug directly effects the idle the hotter plugs idle better than the colder plugs. As for shims, every engine is different, it is used as a tunning tool not a general refference. Accept for the very high end motors that are tweaked to the hilt most other manufacturers send motors out with a 10-20% nitro set-up. Altitude does effect runability the key to remember, is that nitro does not burn well with flame, it reacts to compression, key to remember when your deciding which nitro % fuel to use. Too high nitor % and you could be getting pre-detonation, then you would have to add shims and so on!

Here we go!

Time for the duels at daytona, whos gonna watch, there are going green next time by.

All I know is that JR messed up, even if it was'nt his fault...... or was it? You never know with JR.

BIG TIME!!! should have not even been out there with pole under his belt already. and then trying a 3 car draft was not a good idea!!!! DUH!!!

Yea, but got 14 in the Gatorade Duel and he still can't advance, has to start from the back regardless. DUH!!!!!

Yep! Yep!

two hours of cleaning truggy parts, just gets me more excited about spring. I almost forgot how many parts there are on these things. Just about ready to start tearing into the diffs, new silicone check gears and bearings, re-grease and start putting back together. Chassis is cleaned and then start putting the new set-up on for this year..
