I got a Trinity Platinum A. Drake in a deal for a Truggy. The engine maybe has 12 tanks on it. I have no idea how to tune this engine. I'm not even sure what the base settings are. I took it out and ran it today it ran fine. I tuned it to be rich so not to mess it up. I didn't get more than to tanks through her before I discovered the front diff needs rebuilding. Brought it home took the head off and the piston is clean and shiny still. It gets stuck at TDC so I know it's a fresh engne. Just need some help and some suggestions. It sure sounds mean as hell.

Well i really like what im hearing from this engine. But, im looking between the .24 or .21 (stock, not modded versions) for my kyosho st-rr truggy, which would be better? Oh and what dynamite pipe?
*Bout to put this engine on layaway at my hobbyshop! Is this the best engine for the price?

i think so for 229 base model it just plain rips and low temps and good run times. i think i heard the dynamite 086 but the trinity big boy pipe is the one to run!! i ran a jp3 last year and ed from eb mods told me it was robbing my engine of hpa nd runtime i was getting like 8.5 - 9 minutes a tank and i thought it was fast. this year i am running the trinity pipe and i hear i will get +10 runtime and more power, cant wait. I have the .24 for truggy and the .21 for buggy.

If you run on a large open tack go for the .21 with either the 086 or the Bigboy. For tight technical track slap in a .24 for the low end grunt. Spend the extra and get the prerun version. Trust me, it is worth it's weight in gold.

thanks slaytanic i did mean 086:)

I would go with 24 for truggy and 2056bb, you can still gear it up if you need extra speed, and you wont loose too much low end grunt vs21 with lower gearing.

+1 on the 24.

Is the trinity extech .24 better then the go tech .21 5 port?? Can i run any kind of fuel i want and an 086 pipe on th prerun version? Im goign to order today at the hobbyshop so please help!!!

Definitely better than the Go 5 port, higher quality motor that get's better fuel mileage and has more power. I have a go 5 port as a backup backup and while the motor is good for the price the extech motors are in a different league.

Wouldn't a better comarison be the Trinity .24 vs. the Go .25 (or The Trinity .21 vs. the Go .21)? In either case, I suggest you go with the Trinity if you can spare the $$$.

the .21 race prep is on back order... Should i just order the .24 race prep(both 249)? Now these have been broke in so you can drop them in right??? And do you have to run 30%?
Or should i just wait for the race prep .21?

that is a Picco motor.... run only Picco plugs.... they love the 086 tuned pipe, and they tend to go lean once they warm up.. so set intital settings rich and you will find once the motor fully warms up it will come into tune....never attempt to tune the motor before its fully heat soaked....Picco's are more sensitive to this then any other motor I have found......

Took advantage of some decent weather here in CT. Fired up my Ex Tech. I do have to work on my cold weather tuning skills, but all in all she ran well. Looking forward to the first indoor event next week @ RCX in MA :sneaky:
Thx again Chad :)

Maximo thanks just the answers I was looking for. Was beginning to think no one would reply that would have been a turn off. Actually your description is pretty much accurate I noticed it when I ran it the other day it leaned after it got warm. You wouldn't happen to know the factory settings or where I can find them would you? I'm no rook to tuning I'm just used to Nova based engines. This seems to nice of a mill to mess up going at it blindly. Not to mention it was practically free.

quick question ...got the .24 race prepped today ..cant wait to run a few more tanks through it ....im thinking that my .24 race prepped still had eb mods on it so im thinking it was done by ed and just that amain had it left over from the change over from ed to factory ...which is no biggie .....also does the extech come with a glow plug in the motor ? if so mine didnt have a glow plug anywhere in there ...no biggie on that as i will be running odonells plugs ....be a couple of weekends before i strap it in ...gotta get a few more tanks on the grp .....good problem to have ...but i really wanna strap that extech in there .....:tire:

does trinity have the pipes in stock the bat pipe lol thanks

No they don't include a plug, I've had the best success with the Extech #5 or the OS P4...

im gonna be tryin the o.d. plugs so i will let yall know how they work .....:nod:

I belive pipes will be available Jan 9th? I will have two Extech FM 21's with Bigboy pipes coming tomorrow to do some testing. I'll let ya'll know what's up. I am interested to see the feel of the FM's versus the two EB Extechs I had.

This is the version of the .24 i want right??? And the .24 is best in truggy with 086, not the .21???

Extech Clutch
 

Does anyone run the extech clutch. I have one and need new shoes but can't find them. The clutch appears to be same as the Fioroni Vario but am not 100% if the shoes will fit. Oh yeah, I run the .24 in my trug and it screams.

FYI - the .24 is not like a .28.. has a touch more power than a .21 yet same runtime as .21.. I would only use the big boy pipe with any of our engines in buggy and truggy...

dhopkins - those shoes will work..

just received my .24 pre run today not the extech 2 as advertised by amain but I guess their the same except ed preran this one in and i do like the ebmods stickers lol. nice engine!

So these Extech's are Sirio based? I've just commenced break-in of a Sirio Kanai Evo4 STI, with Sirio 2056 (bat pipe) and am extremely impressed so far, and would like to run a similar set-up in my ST-RR. So if these engines are Sirio based, I'm also guessing the Big Boy pipe is also the same or similar as the Sirio 2056.

Cheers

awe shucks .....mine says eb mods where are my stickers :lol:but yeh mine the same as yours got it yesterday and that was the case ...either way can wait to strap it up:nod:

New to the Forum
 

I just got my .24 pre run today. I want to know which of these pipes I have would be best until I get the BB from A-MAin. JP3 or JP4.
Also Amain did not have the glows. I picked up a P6 "hot" plug I figured a p3 WOULD BE TO HOT. My LHS has order some P4's. whats your thoughts on thes plugs?

Should this pre-run motor get 10 plus min. with the venturi supplied?


Thanks

did u get a dyno sheet? i did its just to light can't read it. I ran one tank today wrapped the head alum. tape and putted back and forth on the street max 3/4 throttle. temped around 195-210. much power even rich like it was. Two more tanks and I will start to lean it out a little. I ran the p4 plug. THe only thing i didnt like is I don't have my Big Bat muffler LOL.

Team Chambers, I ran the .21 in my buggy at the RCP TX Finals at Ncontrol last month. I used the Trinity #5 Turbo plug and it was great. We ran 7 min quals with a hot lap and I still had 1/4 tank or more of fuel left at the end, couldn't get the engine to hit 200 deg. I tried ordering the plugs through the LHS but the distributor said they were back ordered, so I got mine direct from Trinity. Don't know about those pipes. I used a Sirio 2013 on that layout and was very happy with it but it gives you a lot of grunt. 2056 is also supposed to be good, and the Dynamite 086. If you can lay hands on one of those until you get the BB, any of those pipes will probably work better than the JPs.

cjtam....I thought your usernamer loked familiar. Thanks for the input

chad, ygpm

No problem. I have the 2013 and 086. If budget/schedule let me get up there for the Twister you can try them out.

yeh came with the dyno sheet ...they need some printer ink ...mine was light too ...gotta get the grp th erest of the way this weekend ...then im strapping it up .....and will let yall know how the 97t plug does .....later

More like the Xerox needs some ink...:lol:

;)

Ha Ha, I get it now.:rolleyes:

how do you figure on the 97t ......its a medium glow plug .....have you ever run one ....or are ya just thinking its to hot ..... i have had good luck running them in medium plug applications ...on the other hand i have always had bad luck with o.s. plugs .....i think people run them because of there availability and nothing else ...as they are more expensive and dont last near as long .....just my .02 ....not trying to confront ...i just wanna get my hands on your secret glow plug heat decoder ring :lol:and yeh being that the prerun has no modding i could give 2 dumps weather its accurate or not ...im sure the extech will do well :nod:

;)

yeh i mean ive just seen to many o.s. plugs take dumps at the track .and have run od plugs to the point i changed them just for good measure because i felt like they had just been in there to long..now on the determining the od97t plugs were to hot ...how did you determine that ....i mean what were your effects on the engine ...and like what ambient temps was it outside ...chad had told me on pm he didnt know anyone who had run od plugs and to let him know how they worked .....just curious more than anything on how you read they glow plugs were to hot ..just so i will know what to look for ..thanks buddy ...

;)

thanks for the quick reply ...now when you get the patent on the super secret glow plug decoder ring then you mak esure and tell em zixxer came up with the name :sneaky:...thanks again buddy ...and hey what ambient temp and humidity yall run in most of the time :confused:

;)
