KlotzBanshee Posted October 16, 2006 Report Posted October 16, 2006 (edited) OK...I know this question will get a rise out of some of you, and that's fine. But I don't want to hear any bias one sided shit from people who have not researched both products. I want objective opinions with educated explainations PLEASE. Strickly perfrormance speaking, not price, or PR or ease of dome switching, or whatever.... Which Head? NOSS or Trinity? And WHY. I will be buying one of these very soon, and Jeff can get either one.

Dont know if thats the best way to get a response but here goes. Personally I only have experiance with the noss head. It performed well and did a good job with cooling. With that being said I really dont think there is a difference of performance in any aftermarket head. Compression is compression and they all use pretty much the same style domes. I think the only difference may be better cooling. However I doubt that your going to find any rock hard evidence either way. To be honest I think the only difference is the look of the head. Neither are going to be that much better perfromance wise then the other. Quote
majicmike Posted October 17, 2006 Report Posted October 17, 2006 There is a big differance in dome design, the squish angle the step and chamber design all play a huge part in the domes. I have not seen a trinity head and I dont know any one who makes domes for them other than trinity. But the noss uses the same dome as the pro-design and (imo) there is a better chance to find a better dome design with more people making them. The dome plays a huge part in the 2 stroke, not to knock trinity its just my observation. Quote

I just know that there are a lot of Trinity haters in here. And while some people speak from experience many just like to jump on a band wagon and say "yeah they suck" because they heard someone else say it. You both have valid points about the domes. Trinity's domes are quite diff from the rest, and do not work with other heads but I really don't see that posing a problem as I won't be changing them frequently. The reason they're different is b/c they have coolant diffusers near the domes that supposedly channel the coolant down the cylinders to keep them cool rather than just flowing in one side of the head and out the other cooling only the head. The stock head does this by way of the stock gasket but most o-ring sealing style heads do not. But like stated above, there is no rock hard evidence to prove one claim over another, other than gathering as much info as possible on the subject. The NOSS head is very nice as well, they have a tested and true design with versatile components and general ease of use. It Quote
Big Blue Posted October 18, 2006 Report Posted October 18, 2006 Customer service!!!!!!!!!!!!!!!!!! David will help out right away. Avialabilty of domes, say you are out at the dunes and strip a dome out? you will find a pro design/noss style dome just about anywhere. Quote
KlotzBanshee Posted October 18, 2006 Author Report Posted October 18, 2006 I'll be going to Jeff @ FAST. He can get either one and He has very good customer service. :wink: TTT Quote
dajogejr Posted October 18, 2006 Report Posted October 18, 2006 I"m pretty sure the NOSS head has deflectors for the coolant flow as well...check with Dave Noss, just PM dlnoss, or wait for him to pipe in here.... Quote
KlotzBanshee Posted October 19, 2006 Author Report Posted October 19, 2006 If Dave or any one else can confirm this, I'd love to hear about it. I have money in hand and will go with one of these soon. so please help me make a decision. BUMP Quote
csrmel Posted October 19, 2006 Report Posted October 19, 2006 strictly from a performance standpoint, they all the same. each one of these companys has done their homework on dome design and each one of them run very similar shape domes. pick the cheapest one and go with it. or get the stock head rechambered and save a bunch of cash for other things.

dajogejr Posted October 19, 2006 Report Posted October 19, 2006 If money was tight, I'd get the stocker shaved and rechambered... But, the Oring head will seal better and cool better, period. Dave can confirm this very easily, PM dlnoss or call him @ 918-358-3804 Or, follow here....it plainly states coolant deflectors are machined into the head: http://www.nossmachine.com/banshee_heads.htm He gives a discount for HQ members...or, as said, go with Jeff.

dlnoss Posted October 20, 2006 Report Posted October 20, 2006 The Noss heads do have coolant deflectors which ensure that the coolant goes where it should. The domes are interchangeable with Pro Design and probably some other heads but the chamber is not the same unless it is pure coincidence (very unlikely). My off-the-shelf domes were designed with the assistance of TSR racing software, input from a few premier builders, and plain old experience. I also make custom domes if preferred. I chose to make the top half of the dome compatible with the Pro Design so customers wouldn't be stuck with a proprietary design which could be a disadvantage for them if they broke down on a trip or if I got hit by a train or something. The same goes for the orings. Even though my oring sets are usually less expensive than PD oring sets, the sizes are the same if you're in a jam and the PD's are available. I don't know much about the Trinity heads so I can't say anything positive or negative about them. They do look pretty good. ( I wouldn't say anything negative even if I knew something negative ) -David Quote
