Can we please get back on track?

My modded Extech is power extreme! But it delivers it smooooooooth. I want to try to see how much run time I can get. Anyone know part #s for the venturies? Chad said Trinity has em but I cannot find it on the site. I want to go to 7.5 or maybe 7.

is the Extech ED mods pré-run-in engine
almost run-in when you receive it ???
can one use OS¨P3 plugs ??

supralative 07-25-2008 11:04 AM

According to Ed, it has been ran in with 5 tanks.
From reading this thread, people have used P3, P4, and a few other plugs.

Speaking with Team Trinity reps, they say run about another quart of fuel through it...but overall its ready to run when you get it.

yes their 2 differant versions you can purchase theirs the pretty much stock motor wich comes pre-broke in or you can get the EB modded wich has some more work done to it and also is pre-broke in.. i recieved mine friday and ran half tank in front of my house to make sure everything was set right and then went to race that next morning at 6am for a saturday series and raced it all day with no problems ..

i am running the eb fully modded with a os p4 plug i live in southern california orange county and the p4 is what we have came to like down here ...

so what are the pipe choices some of you guys have come to like ????

i have tried

novarossi 9853------+1st best
novarossi 9901
jp1
jp2
jp3
jp4------+4th best
sirio 2013------+3rd best
grp 2053------+2nd best
dynamite 086
os pipe

The Nova 9853 is the best buy far besy milade and power everywhere the thing about the grp 2053 pipe when we ran it was it ran wormer then the other witch we do not want to do it was around 225 compaired to the others around 200 or cooler so with that the nova 9853 it best then the sirio 2013 so far we have a little more testing with different headers on the pipes now then when we get what we want Colby or I will post it hear so everyone knows what we recommend to try.I can say with the 086 we ran the C header we are going to try the nova D header on it this weekend as well to the 086 maked grate power but is to more like a on off switch on teh top end if the D header helps take that away like i'm thinking it will it will be a very good set up to run as well and does not cost to much as well very strong we will post that hear sometime sunday.

The jp 4 was very fast as well but had a dead spot just off idle it is just the way that pipe ran other then that it is not a bad choice as well.

Just got a .21 full modd today and will be testing it tom. I noticed no plugs came with it, not even the 1 that was used to "break in".:weird:
I'll be using 25% and not 30% nitro...availability issues. Weather at around mid 90's, humidity 90sh%, 25mtrs above sea level (dunno if that matters):p
Should i adjust head shimming to compensate for the lower nitro content?
What plugs to use in these conditions?
Any suggestions guys?
Thanks in advance!

what header do you run with the Nova 9853? I have been running the Tsais 2053 with 9 to 11 min run times

gtsum 07-26-2008 07:51 PM

Chad or anyone else out here on the East Coast - what pipe to use for the Ex Tech 21 at tracks around here (Tiltyard is the biggest track I run at..the others in VA and MD are smaller). I currently have a 53, 86, and a 1005..Thanks!

mp3ranger 07-26-2008 08:29 PM

At the tilted yard I use the 2053 pipe

C.Poh 07-27-2008 12:21 AM
