I'm about to send my cylinders off to Trinity for the pro mx/tt porting, but I'm having second thoughts and considering going with Passion racings 12 port. Does anybody have any comments, good or bad, about either of these companies? Any suggestions would be greatly appreciated before I dish out the money. Thanks.

My suggestion is this.... Do a search on this site for porting, you'll get alot of names, websites, email, phone etc. Call around and narrow the list down to the people you really like or thin kyou would feel comfortable working with your engine. Then come back here with your list and everybody will give you the info you need to know about the builders you're interested in. I understand that it's alot of work but IMO it's worth it. As meat always says it's better to do things right the first time.

Go with Trinity. All them years in R&D wasn't for nothing.

They're motor work is tried and true many times over. The only bad you'll hear about Trinity is the customer service. If you run into delays or problems with getting a hold of someone rocketpig on here works for Trinity and would be glad to assist you.

My sleeved 420 with the pro mx porting hauled insane ass. Period.

I chose Trinity on my last build for several reasons and will continue to use them in the future. Though do like Chemical said, do your homework and know what type and style of riding you do most and what type of porting would best complement that. It's not all out horsepower or numbers that you should look at when deciding or you may be very dissapointed. A good area to start is with dyno charts from engine builders. This is the end result of their work, although variables are involved, it will give you a good idea of the performance differences between them. Most companies should be happy to send you dyno test results of their work. If not, choose someone else. This will help you to analyze where you want your power to start and how long it will last. If you trail ride or MX you need the power to come on early, if your a dune rider or a dragger you need it to come on a little later etc. It's a give and take with porting and yes we would like to have it all but it's not possible. Also you will find some dyno's on this site with some searching and luck. Remember also that your exhaust system should compliment your porting style, meaning match your porting. This has a significant affect on your performance. Ok you've been armed, now go do the hunting. Good luck!!
