That is the 0801 pipe.
thanks man!

Mhhh as far as i know, until now i just know about 3 people racing GO's on the worlds :

- Chris Pace (5 port) / USA
- Rodrigo Echeverri (5 port) / Colombia
- Pato Concha (me, 5/7 ports) / Colombia

cya,

I need a piston/sleeve for a 7-port. Seems like a hard to get item at the moment. If anyone can help hollar! It seems everything is on back order. If I can't get before the 20th. I am gonna have to buy a different motor.

Brian Hook me up man :)

Thanks,
T.

Todd, call me

Sup guys, I have a question because I just purchased a Go .21 5PT Combo kit and going to start the breakin this weekend.
Anyway, my friend has the same engine and after breakin his engine is running around 260F-285F degrees with good blue smoke coming from the pipe !
I live in Puerto Rico and it never drops below 70F deg even on cloudy winter days.
His setup is this: Go .21 5PT, OS P3 plug, Maxy's 20% race fuel.
If we try to tune for lower temps it bogs and doesn't want to rev, and at the temps mention it screams with good smoke comming from pipe .

does this sound ok ?

those temps are pushing the limit of power and longevity, the motor should have 30% fuel ran through it, and you will get lower temps and more adjustability on the carb settings and make more power. 250 260 is the max we like to run if the track will take it, if not 220 230 and still make tire blowing power. The plug is good, if the air has very low humidity levels run a P6 this will give some tunning options as well as far as leaning it with lower temps, and helps runtime, run the 0801 pipe and your set.

Mizz ?

sounds good to me. tune for performance and smoke.
if you have a trail of smoke and no performance issues like lean bogging then you are good.

keep a clean air filter on and you will get gallons and gallons of enjoyment!

I had full intentions of racing the GO engines and am grateful for Russell's support, however the Reedy engines are available to team drivers and I have an obligation to run them. Chris and I always do/and will pit together at the worlds, and I wish him and you guys the best of luck.

Will, I ran the .25 in my truggy Saturday nite, with 0801 pipe, it works very well at The Nitro Pit, after 15 minute main, came off at 240, with no hestitation, and plenty of power. With all the pipes I have tried on that engine, the 0801 seems to work the best.

Sounds perfectly fine ! Dont worry about your temps , if the engine runs happy then its a good tune .. If you notice the engine dosent like it when its richer ... We run those engines on as low as 10% nitro and get awesome performance on .3 head shimming

Cheers MM

What plug have you guys been running in the Go .25? and where/or what is the climate/weather, your racing in?

Has anyone changed the head button on their 3-port Race to a standard type? If so, how did it run and what plugs did you use?

We stock all of them here, they are lethal and good for the price.

As far as testing since last season, the outcome so far was as follows:

3PT was lethal on tight short track layout, it out maneuvered any other engine on track when it came to corners, simply lethal. 13T on 48 gearing,

Track was no longer then 320ft.

Temps were tagged on 220 to 235 with 30% nitro on Go cold plug.

Straights were good.

5PT was just as lethal , same gearing / fuel and track.

Temps were much lower, larger sweeping corners were real nice, tight turns and short burst jumps were good but not as good as the 3PT, straight was much better then the 3PT. Could be a gearing choice here or clutch setup.

7PT was real fast, power curve felt like it had some exponential in it, but the sweeping turns and straights are lethal. Still need more testing most likely this season on the new track which is 1700FT long.

All engines were tested on same car same fuel same gearing different days, temps varied a little but nothing major.

Just a note, all the go engines liked a combination of carbon and steel on the clutch.

Go pipe and header were used as well, restrictors were mid sized for all the engines.

These are just our observations here, then again, there way to many variables.

At the end of the day, who can beat them in price quality and performance.

Hi All,

Can someone please tell me what 21 size engine out of the GO engines has the same power (Bottom & Top End) as the Novarossi P5T engines?

I'm after an engine that has the same power band as a NR 5PT:blush:.

Thanks for all your help:nod:
