Needles was set at spec. and have richin the lowend to 1.5hrs do i go more then that? temps are 180 to 190. what was puzzled me was with the diff carb did same thing

Did you check the fuel lines??? Anything wet???? Sounds like you may have an air leak.......:confused:

Yep, New tank, fuel line and even removed fuel filter thinking that may cause air at the top of it still same prob.

Try heavier clutch springs or lighter shoes. Clutch problems can cause all kinds of low end tuning problems.

what pipe? if you have a jp take it off..

Why? is it that bad? how about something from EB as to why?

im waiting on the rev order for a RP .21 and have a JP4 waiting for it... C.Poh said 4th best which should be just fine for me...lol

thx

I had a bad gasket between the header and pipe once that made my engine run like that.I ran a JP-2 pipe on my extech this past weekend and it ran great.Lee

sixpac - ok let me rephrase.. boogeyman had a jp pipe (not jp4) and had bogging issues. sorry should have been more specific :)

right on, im new to this so the tech terms fly over my head! lol

im ready to pull mine out of the wood box and, RUN IT!

THX

We have tested the jp1-2 and 4 and none were to our liking at all the one just was not there at all the 2 had grate top end but that was it and did not get good milage none of them did actly the 4 had a dead spot just as the engine comes off idle and starts to try to run after the dead spot is has good power but that makes it hard to drive and as i sayed they all dont get that good of milage now the nova 9853 is our favorite but hard to get now and not race able as of 09 for big races the sirio 2013 it s very good pipe that you can run in 09 it makes good power and is smooth and gets ok milage as well.. that makes me very happy to hear you will be very happy with it and if you need ay help at all let us know we would be happy to help out

How is the Trinity 2013 pipe for truggy?If not whats a good pipe

That is a good pipe for the ExTech in a truggy.

Colin

dynamite the one they suggest.;)

hmmmmm... If you check everything & theres nothing on the car binding/hanging up, it just may be an air leak. It don't have to be wet to be leaking! Seal it up if you haven't already...

Or like wingracer said below depending what kind of car it's in...

will do! Other then that this engine is a screamer!

oh also it is a RC8

The best 09 legal pipe for any Sirio based motor is probably going to be a 2013. 2018 might be worth trying as well.

at this time yes the 2013 is looking to be the best

my car did the same thing and ed tuned my idle gap!!!said it was to big!!!make sure you set it like the papers tell you!!!

I too have the RC8. Are you using the stock flywheel/clutch set up?!

I tried the mugen flywheel/clutch on it & it felt real good but when I was racing under flex it would just touch the rear brake disk &/or chassis & stop the engine. So needless to say I went back to the stock set-up...;)

the jp4 is a good pipe and is legal the only issue is it is more for a big track where you dont need much bottom i ran this pipe on a track that has a straight away just about 170 ft ,revelation raceway and the pipe was nice just had that dead spot on bottom so running this pipe on a small track your going to be wondering where your bottom is and your going to start leaning wich will make your tune all crazy and idle strange... for a small track 2013 is great and legal ..also the new grp pipe is great for a big track if any of you guys are running at the nitro pit in arizona and have tried either of these pipes out their let me know how it is thanks .....this saturday we are running at Thunder alley and will be doing more pipe testing on the fresh layout :nod:

WORD!

The JP-4, is a (mid to top end) pipe. If anything I'd try the JP-3, it's a (Low to top end) pipe... :nod:

Chad

Why did you say that if it was a JP pipe take it off?? Does that apply to all of them JP1-2-3-4 ?? or just one??

C. Poh-----------Whats the scoop on the GRP pipe in the X-tech? What's it do for top? Whats it do for the bottome end? Run times?

;)

You have no bottom! :weird: lol jk!

i will check this out

Running the frioni, 2 alumn 1 carb

the GRP pipe is very simular to the jp4 wonderful for a big track but also pretty dead at bottom ,i went out a couple thursdays ago and ran it at Rev and it was nice you just had to go wide to hit the jumps coming out of a sharp turn like a 180 but pulled very smooth all the way through and kept pulling down that long straight away lol rev is i believe like 190 by 165.make sure your running the new grp pipe its chrome they switched materials since their release...that saturday i went to arc and ran the same everything pipe,restrictor everything ,this track is smaller probably about 165 to 165 pretty nice set up actually ,the front straight is like 150 max and the GRP just wasnt doing it for me i reset my linkage everything my first 1/4 throttle was missing basicaly it sucked i couldnt drive it was killing me lol..we put a 7 restrictor in it and it still did it ,i put that novarossi 9853 with the 7 restrictor and my problem was solved no more missing 1/4 throttle i hit that triggle and it lights up from top to bottom nice and smooth....

so grp is very nice for a big flowing track but not so lovely on a medium to small track if your track is very high speed and flows very well try it ,if you can keep your rpm's up coming in and out of corners you might like it....if you plan on coming to the Nitro challenge or any race at the Nitro pit bring a grp i believe that pipe is going to be great their.....

GRP run time with a 8 restrictor i got just over 9 min running at 200 on big track...
GRP run time with a 8 restrictor i got just over 10 min running at 190 on medium size track...

7 restrictor nova 9853 10:30 at 170 on medium size track....
8 restrictor nova 9853 9:30 at 175 on big track

over 4 gallons and i still cant turn it over by hand... luv it ...

Thanks for the info. I have yet to try the GRP pipe. Not sure that it would match our style of tracks in this area.

Which motor are you using the Full mod or the Race prep?

i run the .21 fully modded version in my losi 8 and will be running the new ex tech .24 in my truggy i will definately let you guys know how the 24 is as soon as i get to run it ....

;)

The same hear!! for the ones that do not know us Colby and i work together with the all the pipe info we are geting you guys.It's not often that we are not at the track together.

Had a issue with the extech today when I took it to the track to get some tanks in it before the pro series this weekend. I put about 3 tanks through it here at the house last week and it ran strong. Got it to the track today and no matter what tuning changes I made it wouldn't make it around the track more than a couple laps or less. It kept dying after wot and as soon as I would let off and it dropped in rpm it just shut off. I've quaddruple checked my idle and it continued to do this whether I was at the rich needle settings or the tuned settings, checked the clutch and it's fine and my servo epa is correct also. The only thing I can think of is I need a hotter plug, I was running the medium hot extech and just ordered some hots, when I was runnning it at the house it was in the upper 80's and 90's and today it's only 75. I'm hoping the hotter plug solves the problem, has anyone else had this issue before as maybe I'm overlooking something. Thanks

i have a ? and dont try to bullchit me :flaming: me and another guy are running the extech engines and yes we know how to tune 1. but there is no way we are getting over 7.30 mins of run time on our engines. we are both running the 086 pipe i have over a gallon on mine and he has over 2 on his. so dont try this check for leaks and check for that because we have been over both our stuff. i would just like to no what i need to do to get the 9-10 mins run time? do i need a restrictor ? or what ? tks to trinity best engine i have ever had.

As for geting better run time that is a hard one i'm close to 10min but i'm runing the grp 2053 and geting around 9-9:30 we both are runing os p4 plugs and then colby got the best time we have yet it was with the nova 9853 with a 7 restrictor in it now i have the 8 in mine i have not tryed the 7 yet but we did not see much if any difference if any in power going to the 7 other then about 30sec. more run time.What plug are you runing i know that can make a big difference and for run time with the 086 pipe i do not rember but is was not like we are geting with the 2053 i can way as well the plug can make a big difference as well as the track we have ran at Rev and this past weekend at thunderalley on sat. testing and got about the same time at both tracks.Our engines were runing about the 180-190 range all day with out making any changes to them all day.

086 is a pretty fuel thirsty pipe. Try a 2013. Are other drivers getting that kind of mileage at your track? Some tracks use more fuel. Be smoother on the trigger. Go to a smaller venturi. Add a head shim. Drop the nitro percentage.

We do not change the hrad shiming on anything like that we run them how we get them from Trinity/Ed the olny thing we are trying is the restrictor to see if we can get even better millage.

Often adding a shim or dropping nitro % can improve mileage without dropping horsepower as much as a smaller venturi will. Sometimes it's the other way around. Or do both for even more mileage. Or do none, run faster and make an extra stop.

Put a zip tie around the base of the carb boot this past weekend to see if it will help with the leaky carb issue. It did help out alot!!!!.
There is just slight residue now from the point where you adjust the low end. I will probably put some sealent around the boot end there to help it out.
I am running a Power Racing 053 pipe. Great power throughout, but run time isnt quite there yet. Motor still has alot of pinch though. It only has about 11-12tanks through it.
