Graeme,

Thanks for the reply. My 05' speedy is setup as follows.....

Your pipes
uni filter
bottom of airbox and uni opened up
snorkel removed
rejetted to TBS needles shimmed to mimick the length of the stock needles with one shim and 130 mains
AI removed

I'm estimating i've gained probably a minimum of 8 HP and probably 1 or 2 more than that judging by your tests and what snorkel removal felt like and what the rest of the step by step gains i've gradually gotten felt like compared to removing the snorkel which your tests showed gained 2 HP. Now what i'm dying to know is this...

1)-will i be able to simply swap this cam with no other tweaks or adjustments besides rejetting (which is to b expected)
2)-will i have to send my old cam to you (afraid to hear the answer but i think i know after reading the part about the spring loaded noise quietening split gear assembly)
3)-approximatly what will the price be
4)- the BIG one...how much of a gain do you think it will get me with just what i've done so far and no other mods

PLEASE answer all of the questions if possible, tho i realize you won't necassarily know #3, but a ballpark figure would be nice at least. Thanks.
