I have the Sirio 2056, which I suspect is basically the same. I plan to try it soon, depending on when I get my E.T back. Hurry up Chad...not much of the season left n Im jonsin to get what time I can in :P...Thx :)
I will post up my impressions on the pipe once I have the chance.

Another new pipe might be in order, would you say the 2056 has a smooth bottom and midrange Chad?

Chad i bought 2 of the fully modded Ex-Tech 21's .. the one in my buggy runs great. however i put the second one in a truggy and it broke a con-rod on its 2nd race day... if never over-reved or went WOT out of control.. it just broke in warm up at the Reedy race.. Is there anything that can be done?? i bought them about a 2 or so months ago and never really got to run teh one that broke...

nitro - i am lol :)

kthatcher - send it back :nod:

Well fook. I had the LHS order Trinity #5 turbo plugs for me last week, they told me today they're back ordered. Same at A-main. Looks like Trinity may have them in stock, but the 2 weeks they want me to allow for delivery puts me right on the race I need them for. Anybody know where else I can get them? Barring that, which O'd plug is comparable to the #5? Trinity website says the OD97T is comparable to the #6. LHS has a bunch of O'd plugs, just don't know which would be closest.

were calling it the "HOMER' lol the pipe is dialed been running it for couple weeks now ,went from GRP pipe n header to the HOMER and extech header and didnt tune much just had to richen up top,, the homer pulls n pulls but the bottom i didnt have to touch it was perfect,you guys will like it and it gives ya something to joke about when some one sees it and is like WTF with a stund look on their face lol does it work and my awnser is yes it works very well i am running the sidewinder race here at thunder alley raceway and had 10 minute practice sessions and didnt need to pit during the practice went 10 everytime out but i will let you guys know how it is come race time :nod:....have fun guys

If you can't find any #5 ExTech plugs, I would go with the OS P4 turbo plug.

I ran the ExTech .21 pre-run with 2056 pipe for the first time. Runs great, broad powerband from top to bottom. Couldn't get the temp above 180's with a P4 plug, the outside temp was around 48 degrees. It had so much power and a good idle I didn't want to lean it any more. Also, it seemed a little oily around the base of the carb which attracted dirt. Does anyone do something to seal the carb up, I've read of some using a small amount of silicone sealer at the carb base. I figured if it really needed that EB would have done it.

Thanks.

Ran the North Carolina state championships on Saturday at W.C.R.C. Qualified 3rd and finished 5th with the X-tech. You couldn't pass us on their monster straight. I also had the fastest lap of the day in qual's. Still loving the X-tech!!!!

Anyone using an O.S. P3 plug. Temps are getting in the 40's in my area, I'm thinking of trying a P3 if it's not too hot. The P4 runs good but it's hard to get the temp up.

Congrats, cdbias.

I use but a p3 for allround purpose
engine is very stable with it

this engine doesn't get hot at all

So is it O.K. to run in the 170's? I just can't get any more heat out of it. I was thinking about wrapping the head with something to lessen the cooling effect, hopefully getting the temp up to 200. Other than that it runs great, has tons of power and a good idle.
