I am using a Sirio .12 ABC 3 port turbo with NR no7 plug and NR .12 inline pipe ... I found that it do not carry enough acceleration on my RR.
With TC body, the engine is around 115C ...
Centrax / 2speed setting is standard at the moment, what can I do to improve its power ?
PS : I do have an extra NR .15 inline pipe, with this help ?
First let me tell you that Sirio engines have their power band at a higher point than the traditional Nova based engines, so in my track experience I found that to get this engines "singing" you have to use shorter gear ratios. For example in my Yokomo I use lets say 48-45 spurs with Nova engines, with my Sirio I have to use 49-46 spurs (1 tooth shorter), and then the engine really rocks and has an incredible low and top end.
With respect to the pipe, it depends what model of NR inline you have. I personally found that the engine works best with Sirio's own in line pipe S12 200006, or the Yokomo M Mielke in line pipe.
Hope this helps
