hereby the new dyno results.

Explanation

green line:
Tritity 2in1 header with customised linkpipe/collector - Micron silencer - +2mm Throttle Body (+2TB) 62.96HP 72.09NM - 53.16lb-ft Torque

blue line:
2in2 +4mm OTR headers - BSM silencer and linkpipe. 63.31HP 75.68NM - 55.81lb/ft Torque

red line:
2in2 +4mm OTR headers - BSM silencer and linkpipe - +2TB 66.71HP 77.52NM - 57.17lb/ft Torque


The facts:

+2TB
The +2TB I can really recommend! It gave me an +3 HP improvement and a bit more torque.

Trinity 2in1 ( http://www.xt660.com/showthread.php?...hlight=trinity)
The customized 2in1 system will give you gain improvements, weight savings and buttom clearance. But for the best results the 2in2 I can recommend.
The 'Rally Raid' XT by OTR, which has a 104mm bigbore+OTR 2in1+PP head+OTR cam, has got about 63HP according to an article I've read. Mine XT has also almost 63HP with a 103mm bigbore, but with a +2TB. Therefore the 2in1 customized Trinity is much better then the OTR 2in1.

Very nice result. 66.71HP, you got to be happy with that As I told you Marcel, the +2mm throttle body does work, 3.4HP gain.

You have proven the fact again a 2in2 makes more HP then a 2in1. Seen it so many times.

Next mod one of Kenny's new Cams, produces more HP & for longer then a stage 3 HOT Cam. Then a stroker kit. Gee I love spending other peoples money.

WoW marjani, 66, nearly 67hp from an engine that had not much more than 40 stock. Nice work.

some pics of the customised Trinity 2in1 with Micron silencer. This silencer is a very nice one. It has a removable dbkiller and you can take it apart by simply removing one bolt. In the collecter we even made a plug for dyno readings.

For those who are interested in enduro tyres, I'm currently testing Mefo mfc15 enduromaster front and mfc12 stonemaster rear. Got rid of the tkc80's after several crashes in terrain, no grip at all with tkc80's.
