what 14 minutes a tank wasnt enough runtime?

What's your secret dude? I'm impressed. What fuel, pipe, and temps were you running?

Only saw 9 min out of a stock engine and 30%. 10-12 on my modded motor with 30%. One time, a freind got 15+ on a modded engine w/20% White Lightning. Only happened that one time and he was only running 1/4-1/2 throttle the whole race to make it happen.

this pipe

nitro juice 30% fuel

endpoints set to open the carb fully. no radio trim down

so how to the dynamite .12spd hold up?? i think i might buy ona dn send it to ab mods for stage 2 mods?? how do you think it will run?

I wouldn't worry about rushing out and getting the motor modded. It will run great out of the box. The main beifit of modding this engine is to improve runtime. You'd pay more for the mod than the engine actually costs. I mod many of my own engines which keeps the cost down for me. If you treat it good(keep the dirt out of it and keep the temps around 230)most of them will last for 6-10 gallons without any problems. Once in a while you run into a lemon but, most hold up very good.

Again, Just run it as is until you get a dozen or so races under your belt. You'll learn a lot in that time. Your better off spending the extra cash on racing tires. Hint, Hint......

very true, gt is the least expensive class to run in for someone who can drive with some restraint but of the smaller amount spent on it the majority will be spent on tires.. when there is a 44krpm engine spinning the 2 rear wheels on a 4 lb rc car tire selection becomes very important..

To start out i would suggest getting some bowties and holeshots for the rear and the edge and holeshot for the front. that will get you set up for most race tracks.


dont let the class get you down, the old saying is true that running the gas truck class will make ANYONE a better driver with ANY car.

Good advice there.

It's still my favorite class to run.

ya ok. but one thing. does modding help in speed? cause i run a lot of touring cars and im kinda new to the whole motor thing. so will it help top speed very much?

John Schafer

Depends who's doing the work. Most of the time you only get a slight increase in top end rpm if any. To substantialy change the engines opperating rpm range you need to alter the sleeve port timing. Not many engine modifiers alter sleeve port timing. Do some research and ask some questions from the modders your looking into. If they dance around answering the question, look elsewhere.

This is just my oppinion.

ok in the xxx nt... about what top speed will the .12platinum hit?? and what about the .12psd whats the top speed? ok and my last question they are both cheap so whats a good pipe to run with them?

rcdude236

iTrader: (12)

anyone?

Both engines will run about 35 mph. Niether is faster under most racing conditions. The thing is, you gotta get the power to the ground, so traction, tires, and set-up are much more important than which engine has more power.

For what it's worth. The platinum produces more power. It doesn't seem to rev as high as the spd. So with a 20 tooth on the platinum and, an 18 tooth on the spd, the platinum may be only slightly faster than the spd. On the track, you my find yourself fighting the power of the platinum as you struggle to keep from spinning out while accelerating out of the turns. The spd has a much smoother powerband and many times you can actually get through the corners faster just because of the way it puts the power down. Sound hard to belive?? If your a good enough driver you can harness the extra torque of the platinum. The spd is just much easier for most of us to control. Smooth is fast right?


The stock losi or ae pipes both work well. I have not ran the AE pipe but most guys running them are happy.

I love the AE Smoothy pipe on my TZ, and I think it would probably work well on the Dynamite platinum. The Drake pipe is also good, works great with the Dynamite SPD. If you're just getting into gas truck the SPD will be all you need, hell it's all anyone ever needs. My all-time favorite gas truck engine is still the OS CV, but hard to find now. SPD is probably the closest thing to it.

Looper, I assume I'll see you and your gas truck at RCP TX next month?

+1 on the dynamite .12 RE. Great little motor. Won me many races and tuning was consistant. I played around with pipes and believe it or not the best result was using the GT2 RTR pipe. Good on the bottom good on the top and good runtime. If you are thinking of modding, I would go for runtime mod vs. power mod.

ya but i think i want more top speed than 35. my local track here in washington is really wide open. its not tight at all. i mean under 20mph on this track is slow.
