All the info ive seen on here about the subject states that the fazer isnt really based on the thundercat but does have some common parts but basically different bikes hence you cant put a thundercat engine in a fazer or vice versa.It is something the press picked up on & kinda an urban legend.
Whilst looking to see if thundercat brake levers would fit on a FZS600 I wondered why it's widely stated that the Fazer (95bhp) is based on a detuned thundercat (89BHP) engine.How is it detuned if it has more power than the thundercat ? (I understand the thundercat probably has more low end and maybe through the rev range due to the ram-air doo dah ?)It looks like the Thundercat has 87.7 bhp @ 11,250RPM whilst the Fazer has 95 bhp @ 11,500RPM. The Thundercat is allegedly 223kg and the Fazer 189kg. Surely the weight makes up for some of the lack of power ?Don't get me wrong, I'm sure that the seating position and front forks and fairing make the Thundercat a quicker bike, I'm just wondering how the engine is 'detuned', it sounds like an insult since at certain times (??) it will be more powerful than it's brethren.I know Punk likes the Thundercat and that is enough for me to safely believe that it is a cracking bike, this is not supposed to be a criticism of either bike, just a question.I wonder if anyone can point me to a dyno from a stock Thundercat and a stock FZS as that may shed some light on it for me.TIAhttps://en.wikipedia.org/wiki/Yamaha_YZF600Rhttps://en.wikipedia.org/wiki/Yamaha_FZS600_Fazerhttp://www.carolenash.com/insidebikes/bike-reviews/yamaha/fzs600-fazer/
Explains how pointless it is all the boy racers putting these scoops on their car grills as it takes a car so long to get to high speed in the uk that its worthless.
Check the "first thing to do" for cats .
Very interesting Joe, & thats even before ive looked at the link.Explains how pointless it is all the boy racers putting these scoops on their car grills as it takes a car so long to get to high speed in the uk that its worthless......a bike however is surprisingly easy to get to these speeds..Got me thinking now of how to incorporate a bit of forced air for the fazer......just for the crack....if im totally honest i would like it allot better if it also sounded the shizny...i had a K&N typhoon on my type-r & the sound that thing made was worth the sound alone even if it didnt make any hp change.
As I have the Thundercat donor bike I'd wondered about the ram air system being transfered to the fazer but my skills lack for that much, as far as I can tell it would require changing the carbs too, and I'm not sure if that would mean also swapping ecu's, as there's a lot of questions and all my work is done out on the road I don't think It's feasible for me, especially as the maximum time I'd have to play would be a weekend as I'd need it running for work!People should stop thinking the bikes share this and share that, they don't, there's probably a handful of things at most.The extra power of the cat is definitely noticeable, the ram air system isn't just a tube straight into the air box, there's 2 extra (smaller) air boxes in either fairing which the front scoops feed first then it goes into the airbox, obviously the size and shape of these side air boxes do some wizardry to the air flow and possibly density!I do prefer the cat, just for the extra bit of power and its just as comfortable to me as the fazer!

It probably makes more sense to street fighter a T/cat, than add t/cat bits to a Fazer.

A lot of us are guilty of that tho Stig. Here's me considering R1 forks and an R6 shock for mine. Just cos it doesn't make sense, doesn't mean you shouldn't do it. I guess... Are we in search of the perfect compromise, and if so, is there any hope of finding it?
