Is there a difference between the "hard anodized" and the "polished" Dynamite 086 pipes besides pure looks?

Anyone know where to find a good deal on the Go Tech 3 Port .21 engine or the Dynamite 086 pipe?

I have a O.S. .21 VG (P) Off-Road Engine and a jp-3 pipe in my hellfire and it runs strong and it's faster than my sirio .30 and hpi 4.6. I also got it new in the box off ebay for 140.00 Hope that helps.

the Go Tech 3 port engine is out of this world performance for around $100, mated up with a dynamite 086 and its unreal for $150...if you are willing to spend a lil more the .21 5port with dynamite 086 pipe is ready to win races at the highest levels...

soon to be available is the Novarossi short stroke 3 port with nylon carby, interchangeable inserts

this engine will be better than the os v spec but not the os price much less and also more reliable and a longer life span that any other low end engine on the market .

Well, when you say "bang for the buck" you have to consider engine life. The OS engines don't last as long as some of the others... 3-4 gallons under race conditions is what we've seen. So... for 2x the cost of the 3 port OS, I bought a Werks B7 Pro. Local guys are getting 8-9 gallons out of them, pushing them HARD... we're talking about sponsored pros like Hunter Kinsey and Mike Battaile.

In my experience, 7 port engines get better gas mileage... so that's something to consider too. My motor, with a JP1 pipe, and a 6mm restrictor, gave me 9:15 on a tank driving gently. Now, realize it wouldn't do that until I put about 2 gallons through it. They break in pretty slow. That engine is "softer" on the bottom than a 3-port, not as violent right off idle, VERY smooth power curve. When they spool up, look out! The RB engine makes as much power or maybe more (WS7 II/III) but it isn't as smooth throughout the power curve- the Werks has more USEABLE power.

Granted, those are higher-end engines... but they also last twice as long. My bud got 12 gallons out of a WS7 II.

Another of our local "Expert" racers is running the 7-port Go engines... he says 7 gallons or so, and they're only $199. That might be better "bang for the buck" than the Werks... and they're also VERY fast.

I'd stay away from the cheap 3 ports like the OS VG. Yes, you can buy them cheap, but they don't last as long. Novarossi engines last longer... but con rods can be an issue. Note that the RB engines are essentially modified, rebranded Novarossis. For CHEAP engines the Go engines look to be the current king, they seem to last a little longer.

my vote goes for the GO TECH 5 PORT, it has both plenty of bottom and top end and a smooth power band. i would use a JP-3 or dynamite 086 pipe on it.it keeps up to the pro's.

OS .21VG is a pretty good engine.

I also tried Thunder Tiger .21 Pro engine, this is a good engine for the price.
