Jake, usually the manifolds are the same, if your using the same manufacture of each pipe, as so in the Dynamite pipes. This is your old buddy, Veno.

I am in the process of break-in on my 3 port race. I have ran 4 tanks through it while heat cycling the engine. I am getting 3 cycles per tank. What I have started to notice is that on tank 5 it dont want to stay running. Im getting plenty of smoke and temps are at 215. When I go about half throttle then let off and then give it gas it dies. It does not have this problem when I leave the igniter on. Im thinking I may be a little rich but im not sure. The motor was modded by Rick Brake. Any advice would be appreciated. Thanks in advance.

Your plug may be needing replaced.

You sure you didn't mean .02 inch because .2 inch sounds like way too much.

Has anyone tried running an 086 with a longer header on a 7 port? If got an extra JP-3 and I'm thinking about using it's header with a 086 on my 7 port. Maybe even use an exhaust extender to get more bottom.

What is the deal with the engine bearings for the 5 port? Amain says the front bearing is 7x18.6x6mm. Will a normal 7x19x6mm bearing fit no problem?

The 053 pipe really works well with the 7 port, as far as exhaust extender, we used to use the Waller adapter, 6 or 7 years ago, which was pretty much an extender, on the RB engines, that were 7 port motor, S7, WS7, with the 086 pipe, it worked quite well, gave it better bottom and was very linear.

The new GO FEMCA 0801 pipe is basically just that - an 086 pipe with a long header, and they are wicked on all the Go engines.
I run one on my 7 port and it out performs the 053 I had on there hands down. Lot more punch on the bottom and still has the wicked top end you have come to expect from the Go 7 port

Which of the Go pipes work well with the .25 6 port? 0801? 2047? and the differences between an 053, that I have been using on the 6 port.

From what I have read on these forums the Dynamite 086 goes really well on the .25 6 Port. I am guessing the 0801 would work the same or a little better, with more pull down low than the 086.

The Dynamite pipes are great value for money. The 007 is their low end pipe for max torque but not to flash on the top end. The 053 is their mid range pipe with ok bottom end, great mid through to a reasonable top end. The 086 is their high end pipe with ok bottom, reasonable mid and great top end.
The Go 0801 combines better bottom end (due to a longer header) with strong mid and top end, so it pretty much pulls hard from start to finish (on the 7 port it does anyway). The Go 2047 is a good pipe too. Strong bottom and mid, but flags a little on the top end.
Sort of depends what motor and track your running and how you like to drive.
Everyone has their favourites. I find the 0801 on my 7 port is a really good combination for me.

I am not a pro by any means, and some of the others here may be better to answer this question. I was, however, having a similar issue just this weekend. I used to keep my engines around 200-220 when I heat cycled them. The GO engine, however, like to be broken in around 240-260 according to others on this forum. Put some foil on the head, make sure the HSN is flush and lean the bottom ever so slightly and see if this helps. Make sure you are still getting raw fuel out of the pipe (without the igniter on) and plenty of smoke. With the raw fuel, you know the engine is getting plenty of lube and those temps will help with that TIGHT pinch. This is what worked for ME in a combination with the break in procedure on page 78......it is by no means to be used as a guide for anyone. I am now on tank 9 and the engine is beginning to show some life ........I can tell this thing is going to be a beast!

Thanks for you response, I have tried, 007,053,086,JP1,JP2,JP3,JP4, and the only pipe that was giving me the most power, it least it seemed to me, was the 053, this is in a truggy of course, with running on a large track, if you are familiar with The Nitro Pit in Phx.Az. I think the size is about 200X125, so I need a fairly good bottom with mid and top end for any longer straights.

What is the deal with the engine bearings for the 5 port? Amain says the front bearing is 7x18.6x6mm. Will a normal 7x19x6mm bearing fit no problem?

Well I thought something was wrong as it was leaning out at idle today. I took the engine out and looked it over and saw that the carb boot had a tear in it. It didn't halp that my RC8 tank had a crack near the fuel outlet nipple.The latter can be temp. fixed.....not the boot.

Give the 0801 a try, I'm sure you will like it. You may also want to try a 2047 with a shorter header. Have seen video's of the Nitro Pit only. I am in New Zealand some 14,000 miles away from the USA, in the South Pacific

Well I ordered the older needle that supposed to take care of the lsn problems..but now I can't tell if the tear in my carb boot had alot to do with it. The car sounded like it had a air leak. I took a pic of the long needle that came with my 08' 3 port race next to the old shorter blunt needle that I'm going to try. What a difference.
