Chad I just wanted to tell you thanks for what you did for me at the Psycho. It was very unexpected and very much appreciated, it shows me that you beleive in customer support 100% and I'm now 100% loyal to Trinity. In case you are not sure who this is, I was the guy with Martin and Travis Phillips by there RV. Thanks again for you help.

looking at the non modded,pre run trinity 2 .21 for spare and eventually primary truggy engine. my question is does it only need track tuned? im looking to grab 1 and throw in in my bag for when its needed and wondered if i should prerun/break-in myself or need to tune much for conditions...thanks for help


ok i see...looks nice and cheap too...

Pipe Question
 
I just install a .21 in my RC8. WOW! What a nice motor. Can’t wait to get to the track! I have been running a RB WS7III and happen to have a 2045 pipe and a 192 header lying around. Will that work with my engine? I am running a JP-3 now which seems to be OK. I paid a good bit of money for the RB pipe and hate to not use it. I plan on getting a "fat boy" pipe in the near future. :confused:

Rick

tom slick 50 02-14-2009 06:31 PM

i run that set up on my rc8t aswell with the jp3 pipe just ordering a big boy pipe but the jp3 runs ok for me also

While they do put about 3 tanks through it before it get's shipped out it's still a good idea to put a couple of easy tanks through it preheating it before starting before you run her to hard. I'd rather over break it in than run into problems later on if you rush it. Enjoy it when you get it, I just broke in another the other day and I really am impressed by the quality and performance of these motors.

head shims

If anyone decides to send him a engine since his departure from Trinity. I will not be able to replace or fix if something were to happen to it.


2) Shims

.21 Pre Run Head Shims = .038"
.21 fully Modified Head Shims = .028"
.24 Pre Run and .24 Fully Modified Head Shims = .020"

this is for 30% fuel


3) Bottomline - There are no more EB modified engines at the factory. We have not had them for a long time. I know Amain has purchased a lot of the 2.0 Extech's..

Why the difference in head shims from pre run and the mod?
If I remove shims from the pre run what wiil it do?

Chad Phillips 02-16-2009 10:02 AM

pre run .21 - raised top piston

fully .21 - flat top pistion

if u run .028" on pre run, you will ruin engine because it will be to little of head clearance.

itsjusme 02-16-2009 10:30 AM

Did not mean to remove .10, more like .03
What is the performance diff between the
mod and pre run.
Thanks for the quick response Chad.

NitroOB4You 02-16-2009 10:36 AM

I havn't run the FM, but from what I have heard, basically, the Pre will have a more snappy bottom. The FM smooths this out and gives a little more RPM range on top. The FM ( I'm guessing? ) will probably also have slightly better fuel mileage. :)

calibra3 02-16-2009 03:23 PM

Hello.

Please, can any tell me how much minutes can do in a buggy with the trinity .21 full modded please?? I want to buy this engine for my Hyper 9.

thanks and sorry for my bad english.

Itcan very on how you have the engine tuned as well as the size of the track you run on but the normal it from 9:30-11 min. of run time the pipe you run can make a big difference as well we recmond the Trinity Ex-Tech Big Boy 2056 pipe.

What he said :nod: the FM turns about another 5000 RPM on top compared to the pre run but it does this by taking a small amount of the bottom end. So full mod in the buggy for the big tracks and a pre run for the smaller stuff. I run the FM regardless of track size and I still think it has plenty of get up and go.

I always tune the engine about 240F.
My two tracks are little with much slow corners.
And the pipes that I have are: dynamite 053, 086 and OS TS2060.what do you recomend me of this three pipes?( thinking in my slow tracks..)

Thank you very much.


ops ops...another little question.... this engine what glow plug use?
Can I use, o'donell , racers edge glow plugs?? I am tired to buy the expensive OS P3 P4 for my problematic Vspec.

Thanks friend!!

slaytanic 02-17-2009 01:08 AM

Of the 3 pipes you have the first version extech made the most power on the 086 of any pipe tested, Never tried the 053. But i can say that I never lacked for low end grunt on the 086.

boogeyman 02-17-2009 04:51 AM

haveing run the 053 and the 086, it seems that the engine was missing something! and about 2 weeks ago i found out what it was missing. it was missing the big boy pipe.the big boy just seems to add more to the engine all the way around, but keeps everything smoother than the other pipes

You do not want to run these engines at 240 they run in the range of 180-215 with plenty of power you need to tune it to run wright and then use the temp to keep track of it but we have not ever had to run them any over 200 and had more power then needed;) Now those temps i gave you are with the Extech head on it if you change it witch i do not recmond at all it will have to run hoter to get the same power.

For plugs we have come to like the os p4 and when i got cold we tryed the p3 to see what it would do and there was no need we just stick with the p4.

NitroOB4You 02-17-2009 09:20 AM

So, I just ran about 1/2 tank through the "Bat" pipe. I am running it on a Jammin JPX .21, which is the mill I will have for Truggy @ MotoRama (will be running ET's in my buggy for the summer :D) Anyway, all I can say is...WOW! Now, granted, I havn't had it on a track yet, so I can't say right now what it will be like in racing form...but just beating around in my back yard, there's a huge difference compared to the JP3 I had on it. Nice low burbling idle, bottom is solid, SICK mid range to top. All in all, I think Im gonna really like this exhaust and can not wait 'til Friday to practice on track! :sneaky:

sounds good. not sure whether to get the modded(not that i need the extra) or just stay non mod. I have some nice mills sitting around but i need 1 more thats fresh&reliable. il be running either jp or dyn pipe(no fat boy, i have too many pipes already) and just want the extech to be universal for truggy or bug. thx for input, just waiting for refund to purchase

I see the big boys a 2056 so il run an 053...

NitroOB4You 02-17-2009 03:30 PM

IMHO, if you're going to be running on tracks with long straights, try the FM. If you're on smaller tracks or tracks with lots of short run ups to jumps, stick with the Pre. If you're still undecided, consider your trigger traits. By that I mean, do you have a light or heavy finger? If you have a heavy finger, it might be worth while to try the FM as it has a more smooth pull. If you have a more ( don't shoot me for this choice of words, please :P ) delicate finger more of a finesse it around the track, you would probably be fine with the Pre. :)

I am running the Ex-tech full mod motor in my Xray 808, I only just got the car from a mate, it runs for about 7 mins, I have just ordered a big boy pipe, how much more run time does the big boy pipe give you.

SPEEDSKI 02-17-2009 05:21 PM

If I ever descided to switch mills, it would be a Extech. Chad really helped my buddy out a PNB with a new piston and sleeve. His motor went on day one. Chad hooked him up, we broke it in on the bench, and it ran like a scalded dog the rest of the weekend. No money, no questions, no B.S. just here are the parts and good luck racing. You just can't beat the Service Chad is giving. I ran one of the Old EB Extechs:o:o and thats why I switched to RB. I will look at the Extechs again since Chad has taken over.

all makes sense to me. im learning so light throttles me. usually by the time my main rolls around im moderate to heavy throttle. figure the pre is right...thx

romax 02-22-2009 08:33 AM

Raced my full mod .21 yesterday & am very impressed. Still tuned a little rich as i tune for longevity more than absolute top speed. Had a rough day so had to go to 10 min. b main & what a hackfest. Was running second on first lap landed a double into a turn & the guy behind me just plowed me & turned me around then the next 3 or 4 guys turned me over & piled on top & stalled the engine. My pit guy restarted engine i went into panic mode & ran truggy pretty hard & still didn't pit the whole 10 mins. I was the only one that didn't pit. Still had just a splash of fuel left. Very impressed w/ this engine. Will buy .24 for my cen matrix tr as it is a little heavy. Thanks Chad & trinity for a good product.

pballer2777 02-23-2009 07:40 AM

i was lookin for alittle feedback on this motor. i was thinkin of gettin one for my 8t 2.0. so what i was wondering is does this motor have enough power for the truck and is there any issues i should know about. i was at motorama this past weekend and saw alot of guys running them. thanks for the info.

Were the guy at Motorama running them in trucks? :tire:


This engine seems to have plenty of poop and a broad powerband. I wouldn't fret about running it in a propperly geared, realatively lightweight modern truggy like your 8T 2.0. It ain't a Hellfire or an LST....

pballer2777 02-23-2009 10:06 AM

all the engines i saw were in buggies. i didn't notice any in truggies. i was lookin cuz i would have ask them what they thought of the engine.

i should have a full day of practice on my .24 powerhouse rc performance motor after this week end im quite sure the .24 will tote the mail in truggy ...mark smith at powerhouse has done a few of the .24 's including mine ....some of the guys up north he sponsers have been running them and he said on a good tune i should have no issues running 12-13 minutes range ..i will post back after this coming weekend and have some video as well :nod:

EugeneJohn 02-23-2009 10:21 AM

I ran one (.21) race prepped (not full mod) last season in a variety of buggies- LOVE IT! Had the .24 in my ST-RR and it was too much for all but one track (HUGE with a long straight)- tried it at the Mapston Memorial race and was just too much, I stuck the .21 in and it was money. smooth with lots of top end, My CL7B had a little more grunt on the bottom but a newer lighter truck like the LOSI will like it fine. If I had to complain abiut it my bitch is the Carb, The slide is a little stickier than my Novarossi but that's the case on all my Trinity/ Sirio stuff- works fine you just have to be extra carefull setting up your linkage (watch your bottom idle screw- make sure the slide is open/ extended when you turn it in). Great Motor- I have a fresh one for this season (and the old one still screams with about 5 gallons) Definately a safe purchase,

when you say bottom idle screw do you mean the idle screw or the lsn:tire:

romax 02-23-2009 05:41 PM

I have the .21 full mod in my x1 crt & it is plenty. Lets put it this way at my local track there is a single to table top right out of a turn , most truggies had trouble clearing it consistently, i did every lap. Then after i landed it would pull the front wheels if i went full throttle. i think you will be pleased w/ this engine in your 8ight 2.0.

I ran my .24 race prep this past weekend at the Nitro Challenge and it ran great:) It started up with no problems every time and if I let it, it would idle all day long. It had a ton of power and would run for over 8 min. We temped it every time it came off the track and it stayed between 195 and 200 deg. I had people pitting around me checking out what engine I was running and they were all impressed with what they were seeing.

Thanks Trinity for all your help. I'm looking forward to racing my buggy and truggy at the Silver State race.

I think he means the idle screw will bind on the low speed slide unless it is open. I remember something like that with a sirio I had years back.

I figured I would post a video of this thing running too. this was from our main event race. I mixture of different trucks. I'm getting 10 mins out this thing already. ODO 97T still hanging in there Zixxxer, no issues. :lol:

Sholler 02-27-2009 04:49 AM

A couple quick questions for you guys. Just got a ET .24 base model and fired it up yesterday.After hearing it run for about 4 seconds i knew the needles were severely out of whack.Factory settings call for 2 1/2 on the LSN and 4 1/2 on the HSN. so i readjusted and it still seemed very lean, had to go another 2 full turns on the LSN, now it sits just a hair over flush. Same on the HSN. In doing this I noticed the motor is set just a hair on the rich side, top and bottom. Anyone else come across this yet? And it seems the LSN doesnt have much restriction on it, turns very easily. I am afraid with the motor vibration it will only turn itself and lean out unexpectedly. Any ideas to fix this little bug?

Im running byrons gen 2 25%, LRP #7 md-cold, and ofna 086 pipe.

All in all the motor seems like its gonna be stupid fast!!! I`m just trying to get some input so i can enjoy it for as long as possible.
