I have been using OS P3 ultra hot plugs and have been working great.

Yep - OS P3 seem to to be the way to go for turbo heads. For standard heads use any short plug # 4, 5 seem to work well depending on climate.

re plug for go tech break in.
 

since i found the go tech engines have so much pinch you need to pre heat the engine to help start it during break in i went with a mc coy mc59 which is a hot plug as a hotter plu8g makes it easier to get up to temps during break in.

i found my go tech 5 port engine runs really well using mc coy plugs. after i did my 10 tank break in with my go tech i went with a mc coy 8 (medium) for springs races .

now that the weather is really warm i have switched to a mc coy 9 ( cold plug)

Not sure if these questions have been asked before, so here it goes:

Has anyone noticed any significant difference in performance between the turbo and standard heads?

The '08 models come with turbo heads, so I was wondering if I should invest in a standard head also.

And regarding glowplugs....here in Houston, the outside ambient temperatures have been hovering around mid to upper 90's (Fahrenheit) and will only get hotter. According to our local news weathermen, after factoring the high humidity (90+ percent), the heat index(not sure how they came up with this, but you'll see/hear it during the local news) is approx. 102F-105F. Would you still recommend using a P3 or P6? Keep in mind, I'm running Byron's 2nd Gen 30%.

Thanks.

I was wondering the same thing about the ultra
hot glow plugs. Lately, here in Va., our heat index
has gone up as high as 110*.

If it is a standard button, use the plug that came with the engine (Go Tech #5) or OS #8. If it is a turbo button then OS P3 turbo plugs.

just wanna share my hobao hyper 7 with GO.21 5port engine(standard plug)

i miss my 5 port getting another soon along with a 3porter

told yall i had to have one. just got my GO .21 5port turbo installed on my hyper 8.5 pro buggy. now time for break in. but one ? will trinity moster horsepower 20% be ok to break this motor in. also this is the first turbo motor ive ever owned so is there anything to watch out for or i should know about. :confused:

Run the motor in on the same fuel you intend to run it on after it´s run in.
Turbo head is no different to standard as far as runnning motor goes, they just make a little more power throughout the range and maybe idle a little better too.
If you have not broken in a Go motor motor before, be warned they are really tight when new. You will need to heat crankcase and head with hot air gun or hair dryer before you can turn them over on starter box. They stay really tight for quite a while and are only fully bedded in after 1.5 - 2 gal. Bit of a long break in but worth the wait :nod:
Use the PTM break in method on the bottom of page 78 in this thread. It works really well and your motor will run strong for a long time using this break in method.

I've run P3 turbo in a .21 5port in outside temps from 50F to 112F, always seems good.

What % fuel do you run? What was your engine temperature when the outside temperature was at 112F and using the P3? Would you run this setup in a 30+min amain with that temperature?

Just wondering because I have a race coming up next week and weather is forecasted to be a scorcher.

Thanks.

I just went through my 3 port race and my sons 7 port we've been running since Feb. There is no wear on the crank pin or rod, I pinch motors for myself and other people and I have not needed to pinch a Go yet. Man these things have some nice materials in them!

my pinch was fine i just broke a screw off in the crank and put another crank from an inferior motor and the crank split in half right at the carb. lol

thanx grizz1 ill do just that first thing tomarrow.one thing i wasnt clear about do you start break in at the settings out of the box or what.
