I think it is a 12. Saying that I know a dyno where it will make more than 100 and make yours look down on power ZB

it's a 2008 12, that dyno is pretty conservative, i'm not overly fussed with total output just what gains i can get

Highly technical stuff going on here, especially the house brick stand. Love the headers. Where could I go to learn a trade like that (welding etc)?

Seems a hell of a lot of work for 80hp, nice looking can though

Only for one morning a week to get me out of the office, but don't do stuff over level 3 (although I do have an autographed copy of the AC Davies 'Bible' - my Dad trained with him )
I'm sure someone would learn a lot more watching you carry out your Craft

A lot of FE Colleges teach classes in the evening, whatever you do, don't rush out and buy a cheap Mig set and teach yourself

£550 for an 18 week C&G course at Poole Tech. 3 1/2 hours per week. Should be similar price countrywide.
They teach Mig and /or Tig.

I know different dynos tell different stories. I was surprised to see numbers that low. You need to have a play with it pash and set the fuelling to to zorst.

Yeah man, from my (limited experience), on a Dynojet dyno, a good (pre-08) XB will make 90ish, a good Thunderstorm engine 85ish and a good Lightning (pre-Thunderstorm) engine 80ish.

The 08/09/10 models appear to be a bit over 5 10hp down, I would say due to the smaller headers.

Alan and I plan to hook up to create some maps for all his exhausts. I am confident we can get a few more ponies out. We have got plenty of things to try, including the ukbeg 04/05/05/07 12 headers with slave lambda bosses. We also have the ukbeg 08/09 headers (I could do with another boss on to make them 10 compatible also) to help us.

I am sure someone is going to put me straight on my hp figures.

The most important thing with these tests of one setup against another is ensuring that the baselines for everything else that is not changing to be as close as possible. This is hard enough to achieve when you are using the same dyno. Comparing results between dynos in my opinion is almost meaningless. I would imagine there lots of 100+ bhp bikes that would struggle to live with some that are giving out 90 genuine horses.

Oh and driveability is much more important to me than outright peak BHP. I think that the curve shown is a good improvement as it sits where it is needed in the midrange and that is already strong for a Buell.

Oh and finally if it looks good and sounds good too then double bubble.

On a side note the best looking and sounding exhaust I have ever seen on a Buell was PH's Freespritits Reverso very highly polished and on acceleration it sounded lovely deep but not too loud. Such a shame he was never happy with how it ran.

Yeah, I agree, but you would expect a Dynojet, mass produced, dyno to be *quite* repeatable between units where they were maintained to Dynojet's standards. Comparing to another brand would not be meaningless. I would say quite repeatable means within +/-5% or so.

The dyno charts shown are at wide open throttle. I would say this is not a demonstration of driveability cos how often have you got your throttle pinned to the stop? Even overtaking I don't have my throttle pinned.

Driveability is all about getting fuelling and ignition right at part throttle and this is best carried out on the road prior to any refinement to ignition which can only really be made on the dyno, although some estimates can be made based on an assumption that Erik and the Elves got it right with the stock exhaust and more fuel at a point means more pressure and therefore less advance.

As for the exhaust, I think it is a work of art...

look on the bright side, it may be a lot of work for 80bhp but a reasonably simple bolts on for 5bhp mid range, my wife rides this bike so i don't think she's that worried if it makes 80-100 or more, just need pash to wave his magic wand over it and we'll be away
i don't know how much if any difference its makes but this dyno is a twin roller set up for cars as well, when i had the 1125 on it the other week it only made 104 with a standard can but it was misfiring all over the place, another bloody job to sort out. and i have man flu now just in time for the hols

Wel it seems that the dyno might be making a 15-20 hp difference on the low side. I would have thought those headers will help as fitting the pre 2008 ones seems to really pep up the later models. Hence why they are so rare now everyone is after them.

Pash is correct about the riding on the road and logging data. His was the 90bhp Buell I was talking about his Firebolt has to be ridden it really is a pleasure due to it smoothness and grunt.
