Yes, front cylinder runs richer and HOTTER than rear.

Thanks that makes perfect sense. I didn't know that about the connecting rod. I would have assumed the front and rear rods were 180 degrees apart on the crank. So what you're saying is the front piston follows just after the rear piston and the rear sucks in all the air and there is not a lot left for the front? So increasing the intake volume allows more air to be left over to fight this problem?

Yes.

That one pin design gives Harleys their unique sound.

Interesting, thanks for the explanation.

I'm installing the same Mini Cooper Eaton M45 on my Buell, but doing a bunch of internal work to help hold it all together.

I've found these links that may help us out on sourcing some inlet/outlet parts, and throttle body positions/number of throttle bodies.

I'm on the same boat with you guys that fabricating a custom intake manifold would help a lot!

Nice!

It would be interesting to see some pictures of your project. And setup of yours.

Are you saying you are overhauling the charger, or going to strengten some engine components?

Are you going going to locate your TB on chargers intake site?

There are some advantages and disadvantages on assembling TB on the intake side.
Assembling TB/TBs on the chargers intake side air would have to take much longer to get to the cylinders. But then you would'nt have to make boost plenum, because then all volume that is between TB and intake valves is count as a plenum. Then also the plenum gets easily too large, and it poorens a throttle respons.

For example:
- m45 supercharger is 0.737 L
- 200mm x 52mm pipe = 0.4248 L

Today I made belt tightener.

Hand made roller.
A bit heavy though. .

Welded some aluminium as a lip and so on.

I'm in the gathering parts process right now. Blower, injectors, twin manifold seals, clutch pack/spring are on their way.

Blower is brand new, going to strengthen the bottom end by rebuilding, truing, balancing, and installing carrillo rods. 1250cc cylinders, custom pistons, head work to drop the CR to 9.5:1, entire valvetrain/cams.

Not sure on where the TB will be located, still doing research on pros/cons, but I'd like to fabricate a better intake manifold.

If someone is looking a threaded IAT sensor for turbo use. I did some research and found out that 88-93 Fords use that same "caliber" IAT that Buells use:

Newer Fords use same IAT as well, like Ford Mustang SVT Lightnings, SVT trucks and Escorts for example.

Those IAT's are with 3/8 NPT threads.

Anyone happen to know where to buy throttle bodys shaft seals?

 

[EricZ]

There are many different designs for butterfly shaft seals. What throttle body do you want to find seals for?

Are these all same parts?:

XB9 rotor/sprocket - 30018-08 seems to be same aswell ?

I got bored and made new plenum..

2.5 L and charger dropped a bit down also:

Where will you put your leg and why did you have to cut up a transparent cover??

 

[buellxb9rs]

Dual intake is difficult. With the xbrr a different head design was used to offset the two intakes so dual throttle bodies could be used.

 

[mrNICEGUY]

Leg is going outside the belt. That belt is less than 2cm wide. Need some belt guard though, otherwise I could get my snorkle to get cut. I've been looking that Lazareths SC Buell, and ended up conclusion that they have modified lots of thinks to get room to that belt between knee and the frame.

Had to cut that cover for that supercharger.... Going to fiberglass it up, when all parts are assembled.


I've been thinking to use BT's dual intakes and some dual throttle body: http://www.ebay.com/itm/1995-94-95-...Parts_Accessories&hash=item4175332437&vxp=mtr

BT's ports are ~2cm closer each other than Buells, so I think it would'nt be so hard to widen it up to fit on Buell.

But that needs lots of thinking.

 

[mrNICEGUY]

Any opinions for this one: http://www.ebay.com/itm/FAST-Wide-B...Parts_Accessories&hash=item58aca97bd5&vxp=mtr

Is there any way to switch between fuelmaps on road, so that I dont have to carry a laptop with me and so on...

It would be great if there is a way to swap between e85 and pumpgas tuned maps on road.
