How does the FM.21 run with 20%.. Do you have to do anything with the head shims? Glow plugs?

I just bought the FM ex tech2.. I have the eb modded first gen engine.. is there gonna be a noticible diff??? or are most of you happy with the Gen2 motors???

I had the EB FM gen.1, then got the pre-run gen.2 and the there is a slight difference but the power seems much more linear, i really like it!

Thanks...

actually on my .24 eb mod your right ed there were shims. just too many of them thats why i had no top end. there are supposed to be 2 shims not four, thus causing no top end. but of course ed would deny it had four shims or he had anything to do with it.

Hello.
I am Henry from Spain.
Please, first, sorry for my bad english if I not write perfect..

well...

I want to buy another engine as backup.
I race with a truggy jammin X2-CRT and a new OS V-spec and I am very happy with his power.

But I have a dude.
I have read about the trinity full modded , and I think that I like it.
But this new engine has the same power of OS V-spec or have more power on bottom and top end?

I don't want disturb anybody with this question, Only ask in this thread for answer my dudes, because I like this engine.

Thanks for all.

Has anyone tried the O.S. 2060 pipe with the .21 FM???

hows it work???

how can you work on an engine if you dont reply to emails?

Yes when Colby as me did pipe testing when the engines ware frist avable to us that is one of the frist pipes and it has a bad dead spot on the bottom end and just ok everyware alse we both recmond the extech 2056 baseball bat looking pipe it is buy far the best for the .21

hey chad or anyone that knows for sure what is the stock for 30 percent fuel shimming on the extech .24 seems to be some conflicts ...zixxer just wanting to make surebut seriously what is it 1------2--------4------im pretty sure mine has one silver shim ...which is what eb said he put in them ....

chad told me today on the phone 2 silver shims on race prep model

well I've made up my mind i'm getting the FM 24. Hopefully its' the factory mod and not the EB mod. Is there a way to tell the difference in the two. If I receive the EB version I'm sending it back. I don't want to go down that road... lol.

Please don't forgive me... I want to know if this engine it is more powerful than the Vspec, for change it..

Hi All,

1) IF anyone has a problem with a Trinity engine whether it is a EB or new one. It has to come to us for warranty. Dont know why Ed posted that. He does not work for us anymore. 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..

the .24 would be an excellent choice in your truggy. Our .24 is more powerful than a O.S.
