Chad ,
I must say after being totally confused on which engine to buy i finally narrowed it down to vspec , extech or jpx 21. I read every post on this thread (took about 2 hours) & after seeing you reply to post & your good support after the sale it made my choice much easier. i ordered the full mod .21 last night & should be getting it soon. I do have a few questions. I was thinking of running byrons gen 2, 20% Since we run it in our grp.21. Would it be o.k.? What should i do as far as break in ? Thanks very much.

Hi Romax,

Thank you for Choosing Ex Tech.. I will help you in any way I can.

You can run 20%. You will need to remove 1 head shim.

The fully modified comes partially broken in.. I would run another 4-6 tanks rich before really laying in to it..

I still think you should run 30%.. for one, more power and two, will run cooler..

thanks again..

just got back from my brothers house I were running his rc8t with his new extech .21. It a great engine a lot of power from bottom to top cant wait to see what its like after a gallon and the right pipe he was running a jp-3 on it I'm still going to try the orion .21 in mine but if i dont like it i'm picking up this engine.

Chad , thanks for the fast reply . I'll switch to 30%. If i'm reading right it's allready set up for 30% correct?

romax - yes it is shimmed for 30%..

Chad, what's the runtime like on the stock .21 in a 1/8 buggy? Need to pick up a backup/short track/club race engine here pretty soon and thinking about the unmodded Extech.

stock / pre run - depending on the track and if you use the 2056 pipe.. 10+ minutes..

chad good luck this weekend you homo see you at motorma

got "MY" Trinity Extech EBmod engine back from you yesterday, now shimmed properly and it runs insane thanks for the great customer support!!

Frank - cool..

I just got a modded .24 for my 8ight-t 2.0 and am using the Trinity 2013 pipe getting 12+ minutes on it. I am looking for the Big Boy, anyone know where they are in stock? I've seen this pipe on a friends ExTech .21 and it's helped the power band and run time.

If they aren't in stock at Amain you may have to give Chad a call and see if he can hook you up.

Sent him a pm yesterday

well by now he is at the Psycho Nitro Blast in Atlanta GA, so he will be busy this weekend. I' heading down this morning early. It will take around 3 1/2 hr for my ride.
