Trinity engines are made by Sirio.
Grp also produce engines for several other companies

Falcon, Boss etc

they are a stand alone engine manufacturer and the company was co founded by Mario Rossi as in Novarossi

1) as long as i don't lean it out...much...set my end points to 75%...set my throttle exp to say 65%...run on pavement (so no load).....take one complete year on break in (and i use my break in method not anyones elses)....i shouldn't toast it right ?

2) I've heard bad things about those brands too...

3) i'm sure their warranty is as good as any other warranty....

assembly of my innovative/king headz/speed .21 crt is complete but i still have to put it on the setup board....i probably wont run it till april or may...in the mean time i am practising with my so-so stocker...i'm currently trying to decide if i want a .12 or .18 in my crt .5.....i found an eb mod .18tz..but i'm afraid it might twist the dog bones or be so wickedly torquey that it would be pretty much uncontrollable on dirt....i still need to (for the umteenth time) finish re-assembling my shelf queen savage...i might have found my pit man - the jobs still available if anyones interested....i'm still looking for pieces of my original crt that was run over by an 18'er...which is kind of ironic as i drive 18ers....i'm taking back a cr and hyper that i gave to a friend...he's not interested...and my new pit man is...i might be a newbie but i learn quick...this hobby is a money pit....ahggg,...

The OS Vspec is a good engine, but OS has bad QA, there is too much I've seen go wrong with the engine, the conrod bushing was loose or a bad bearing here or a issue here, same with the speed but with more quality parts you don't see it as often.

I was burned by buying a nova rossi on line, the engine felt ok when I got it, so I put it away and when I needed a back up the main bearing was bad....falling apart, it had already scratched the pistion and sleeve. If you are going to buy a used motor, buy it at the track or locally so you can look at it before you buy
