FYI- For those that don't know, Trinity is moving to FL. From what I can gather, Chad is going along for the ride. Now I gotta pay fuel HAZMAT fees 
...lol. Anyway Good luck 
, hope all goes well for you all
I've got a (approx) 5 Gal E.T that I've been having issues with. Upon removing it from the RC it was in, I found the pipe was badly flattened on the underside. This was at the end of last season. Until today, I havn't really had a good chance to test it out with a new pipe. Basically, on the old system, I would run maybe 1/2 tank and then POP...goes the plug. Went through this with quite a few plugs, figuring it was a tune problem. Well, today I gave it one more chance with a new pipe. I ran ( so far ) only 1 tank through it, and had to richen 'er up a bit on bottom, but other than that it ran the full tank...not even a spec left in the tank when it flamed! I'm 99% sure now that the pipe was the problem and it is all good now. Hopefully soon I'll have a chance to get 'er back on the track for some "real" testing

Went and ran the Silver State race,
Motors ran well with the Big Boy pipes and the 8mm carb insert. Was still getting over 10 minutes of run time and had plenty of power. Was running the '08 tuned versions. I did have one of my heads brake while there in the mains. Didn't notice it until the main was over. The pipe in the buggy had a couple of good sized dents in it, but didn't seem to affect the performance. If anything I may have gained a little topend and lost a little bottom end. Over all, couldn't be happier with the motors. They have never let me down.

Big Boy on my .24
Well I just put on the Big Boy for the first time...Mixed results for me..Overall positive.
It definatley woke up the bottom even more, not that it needed it. Idled better, and I was able to lean it out a bit more bottom and top.
It seems that I lost some top over the JP-3 with a mid-range header combo.
The top never seemed to peak and almost always seemed rich, as it would slightly sputter around the top..not a lean bog sputter. It also ran quite a bit cooler even though it was leaner.
Has anyone else notice the top end sputter. Maybe I need to lean it out some more? It already is about 3/4 turn in from flush on the hsn...
Is the BB pipe known to shave a bit off the top???

My Trinity FM .21 just keeps getting better and it gets some fuel through it. We brought home a win today at Bullet Town R/C. Motor never missed a beat. Running a Dyn 086 pipe and the motor just rips from bottom to top. Pitted at 8:30 minutes. One of the best engine choices I have ever made!!!

Big Boy Update
Well, I leaned the top nearly 6 hours and richened the bottom about 2 hours. It rips hard and I could probably lean the top another hour as my temps were barely hitting 185 - 190.
As far as the O'donnel plug question, I have not used them. I use the OS P4. No problems with them & they easily last me 2 gallons plus. Also I read on this board if you use OS then you need to stick with them as the thread pattern is slightly different and another brand may not seal completely after using the OS brand.

97T vs p4 plugs in FM 24
well I have ran odo 97t plugs in my motor all winter and they seemed to work. as it got warmer i couldn't get the tune right no matter what i did.
the motor would run rich and have a pop on top end or would develop a bog down low if leaned out.
I switched to an OS p4 plug without changing the tune and I could barely get around the track and this was with a race tune on the 97T plugs. after leaning it out the motor ran like the beast it is. spinning wheels down the straight is not a problem.
The ODO 97T is definitely hotter than the P4 and I feel the p4 or p3 are the perfect plugs for the motor.
I've had guys come up and take pictures of my truck and ask what the hell kind of motor I'm running. It's a beast and hard to beat in the power to fuel mileage dept.
I let one guy drive it and he said it just felt like too much power and the rpms climbed too fast for him....not a problem for me haha!! You do have to hold back when racing or you start going slower cause it will spin the tires like crazy if you pull too much trigger...just what I wanted.
Did I say thanks to Chad again. His support made this purchase happen and I don't regret it one bit!!
