i tried that with my 3 port race spec. i tried to use a headbutton from a RB CONCEPTS 5port l2g with stander plug, i found that the standerd head button was too thick, it measured (i think ) .030 thicker than the turbo plug head button. so i wouldnt use it that head button unless it was ground down to the same size,(or thickness) as the turbo head. but i bet the head button from the 3 port sport motor with the blue head from go-tech would work? I AM NOT A RC CAR MOTOR BUILDER. SO PLEASE SEEK THE WORD FROM A PRO, OR ASK THE BRAIN FROM PRO TWISTER MOD FORUMS FOR A better ANSWER. :tire::tire::tire: hey man where do u race at? i race at Redline Raceway.

The 5PT is similar, you just need to have the right gearing and clutch setup, you will like it better....

I was looking at my Novarossi standard button and it is too thick as well. Before I bought one, I figured I would ask here and see if anyone else had tried it.

I race at the RC Outlaws track in Collinsville, IL. Although, with the way things have been going with the weather, I may start going to Dirtburners in St. Louis, MO. We race every other Sunday whereas the Dirtburners folks race every Saturday...double the chances to get some track time in! We have lost a third of our race days to rain this year.:cry:

I use the Go No. 5 plug. I know people who use an OS A3 with good results.
I am in South Eastern Australia and we are in early spring right now.
Temp is around 55f - 64f at the moment. But will get into the 90's over summer, I use the same Go No 5 plug year round.

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.

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!

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

Thanks guys for those response's I'll start the breakin this weekend !

E-Dog make sure you heat up your engine with a heat gun to loosen things up when your doing the breaking... it's going to be tight as hell....

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:

The Go 5 port Pro does

I have a .21 3 port standard head in my kyosho very nice engine i love it. I have a Dynamite 007 Ht exhaust on it now, but soon im putting a JP-3 on it. I have a few questions though.

When this engine goes im thinking about getting a .21 7 port turbo head, i mean what exactly does the ports do and the turbo head. I understand that the turbo plug is tapered and the motor has more ports but what does it do to make it run so much better. The cost of the .21 3 port is $125 and the .21 7 turbo head is like $210 so i wanna understand all this before i go spend the money. One more thing is a motor with more ports and a turbo plug harder to tune then a standard head and less ports?

A close buddy of mine just got the RC8T and to me your truck looked pretty dialed besides that mild push...in fact a lil push would be good for him i think...he doesnt know where to look for setups and I remember your Vid from watching it! Nice Vid by the way!

A 7 port has more top end than the 3 or 5 ports, the 7 port has 3 exhaust ports which is what give it more top end. As a general rule of thumb more ports means more top end but not always the case. The 5 port has the most bottom end of the Go motors.Do tou have the 3 port sport? If so I have experimented with some mods on the sport and I like it better than the 3 port race spec with the mods.
The turbo plug is just a better design and seals at the combustion chamber instead of at the washer, you could probably feel the difference between the two plug styles but not a big overall difference. The 5 and 7 ports probably will tune a little harder than a sport motor but they tune pretty easily.

What head shims do you use in the 5 port? and can someone tell me if you can send these back to get re-built? or just cheeper to buy a new one
