The 2047 has been the pipe of choice for alot of european drivers with the 7port. It hasn't been mentioned very much because the U.S. is not required to use 3 chamber pipes. Plus with the low cost and high performance of the dynamite pipes they seem to offer a good value.

Makes sense. Thanks for the clarification.

gud am guys can i please ask what maximum temp can go .28 redhead can go before overheating?and what maximum safe temp it can reach when racing?tnks guys hope somebody can help me peace

Like most motors, a safe maximum temperature is around 220-240 f.

thanks a lot sir satoch

the GO motors seem to run very cool, not to cool though but a safe lower temp range for sure, the 5 ports stock seem to be very good at 220 to 225 modded a little less, the 25 and 28 should be the same. If the motor starts to get to hot, it will let you know, or the plug will. and if it is new just give it time it will drop in temps, a new motor tends to run hot intill the pinch is almost gone as Russell stated. I have a 5 and 7 port that i have done for a customer with a gallon and a half ran between the two, and i havn't turned the LSN yet, and temps are about 220 on both, still fat and a little tight, but when they get free the carb get's leaned and temps come down.

Thanks

Probably moving to Go engines!!
Go 5 port or 7 port on a buggy?
I do prefer runtime over power so i don't care which one is fastest, just which one will give me more time in the track than in the pits.
Note that i come with v-spec experience so i want to expect similar runtimes and good power.

The 5port gets slightly better mileage, It will have much more bottom end power then your vspec and pull more linear.

Ordering two 5-ports from my LHS tomorrow. One for myself and one for my brother's Christmas present

w00t!

I wish I had a brother

LOL!

What runtimes do you get with the 5 port and what should i expect with the 7 port, on race conditions of course and going FAST?

With the stock restrictor you should be able to pit at 7.5 min. comfortabley with both engines, run time for the 7port is around 8-8.5 min. and around 8.5-9 min. with the 5port. Some guys have gone 10 with the stock restrictor in the 5port but thats not common. To give you an example of how much a difference there is betweem drivers here is a quote from sgrid about a 7port that was run in an endurance race.

We ran a Go 7P Turbo yesterday at the 2nd Annual GMK Supply/Wolcott
Raceway 3 hour Buggy Burndown. The engine ran flawlessly with great
power for the entire 3 hours - not a single flameout or hiccup.

Perfect example of how much the driver is the variable. The most
trigger happy of the four struggled to get 7 minutes. As the oldest
and slowest of the team, they pitted me at 8:30 but said I always had
enough that I probably could go 10. The other 2 were in the 745 - 815
range. Same car, motor, fuel track on the same day, under real race
conditions. YMMV.

They ended up 3rd place.

Please remember that your engine will not get good mileage till after the engine is fully broken in at the 1-1.5 gallon mark.
