Just what I needed, a liter starter box for away races and I'v been wanting to try some pressure line cooling too.
Nice one GO USA.
Will these be available in Aussie land too ?

guys, which pipe work best (if there is) with the GX5R? Or better, what are the essential pipes? HN 2027, Go 2072, Losi RE-10, TT 2035, Werks 2013 etc etc?

Currently I have a Dynamite 053. I love a little bit of variety...

Machine's RC Hobbies will be selling them shortly. Also ask Maxy Valasco. I'm shipping some to him next week, and also some to his brother George in Venezuela. For brazil, you probably want to talk to Pato Concha.

I'm using the 2072, with a great bit of success. I'll also be testing the 0801 next week. I would also try the VP Pro EFRA pipe.

2072 will wipe the floor with the VP pipe as it's 3xxx series. As long as you can run the 2xxx do it as there is no single 3xxx pipe out there that would be as good. Werks/Sirio 2013 is probably too much bottom for the GR5R and would be better for GX7R and the GX3R.

2072 pipe is killer on all the GX Series (3, 5, 7) as well as the previous Pro Series motors.
The 0801 is good too, but not as good as the 2072.

The Dynamite 053 you have will work well on the GX-7R, not so good on the GX-5R or GX-3R. In the Dynamite range the 086 is the go for the 5 Port and 3 Port - but spend that little extra and get the GO 2072, it will be money well spent.

Thanks Grizz1!

What does that mean? If it's my clutchbell literally EXPLODES during take off then I don't find it as a problem. Yeah, am gonna get the 2072. I'll probably run the car in late January or so :nod:

The 053 suits the 7 Port beacause it is a mid range pipe. The 7 has massive top end already, and this pipe helps to bring out the bottom and mid so the overall response is very smooth. The 3 and 5 Ports have good bottom end, but do run out of legs at the top earlier then the 7 Port. The 086 is a top end pipe which helps to pull more power out of these two motors and increase top end performance, while not detracting from the bottom end performance too much.
Somehow GO have made the 2072 do all of this in one pipe :sneaky: Clever buggers ;)

I've a go tech 3port turbo with red head. The silver part of the carb (that goes inside the crank case) is rotating around the plastic, in the past I've tried to glue it on with some tire glue but it keeps on getting un-done...so my question is..

1. Do I need the complete carb assembly or just the main body?
2. Also i'm thinking about getting a new p/s/rod set...would the one for 5port go tech work in my crank case?

Hi xjqkz, you have a couple of issues to deal with here.

1. Carb. To be honest I would spend the little extra and get a complete new GX Series carb. They are far superior in tuning and performance.

2. This all depends on what Generation your 3 Port is. If it is a Gen 5.5 (with the flames on the cooling head and a black crankcase, then you should be OK.
The new PRS sets contain the 21-0600 con rod, which will only fit the newer cranks with the larger diameter crank pin (Gen 5.5, GX and MG66).
If your motor is the older Gen 5 version with the plain head and a grey coloured crankcase, then the new PRS set will not be OK - unless you get an older 28-0600 con rod and change it over, or fit a new GX Series TiNi coated crank to your motor to accept the newer con rod.

As far as putting the 5 Port PRS into the existing crankcase, all PRS and crankcases from Gen 5 onwards will interchange. You just have to be aware of the different con rods and crank pin sizes from Gen 5.5 onwards.
Hope this isn't too confusing, but I would hate you to buy something that wasn't compatible :cool:

I am confused.

1. Can the GX series use the 28-0600 conrod?

2. What conrod does the older 7 port? 28-0600 as well?

THnaks!

Here's how my engine's cooling head looks like:

No - the GX Series cannot use the older 28-0600 rod. They require the newer 21-0600 rod.
Here is a post I did a few weeks ago on the subject. It might help to clear things up -

"CRANK SHAFTS
Gen 5.5, GX Series TiNi and MG66 TiNi coated cranks can be fitted to all Generations of GO engines - but you must use the right con rod.

CON RODS
The new Pro Con Rod (part # 21-0600) can only be fitted to the Gen 5.5, GX Series TiNi, and MG66 TiNi cranks. This rod is NOT compatible with any Gen 5 or earlier motor.
The Gen 5 and earlier motors require the older Pro Con Rod (part # 28-0600)
Reason being the differing crank pin sizes and internal diameters of the con rod big end bushings given by Massive Mods in his earlier post.

TiNi WRIST PINS
These are compatible with all the GO motors."


FYI -

Gen 5.5, GX, MG66 - Rod ID = 5 mm & crank pin dia = 4.993 mm

Gen 5 and earlier - Rod ID = 4.98 mm & crank pin dia = 4.973

You can see the problem. New rod is too sloppy on the old crank, and the old rod is too tight on the new crank.

That looks like the older Gen 5 model to me. You would need the older 28-0600 rod for that model. You can buy a new GX PRS set for that motor, but you would need to swap the new rod for the older 28-0600 before you fitted it.
To be honest, I would spend the extra and get a new GX motor. They are far superior in many ways. You gotta go with the new technology :)

I think I've missed out on that one...

U da man grizz1!
