Ducati S2R 1100 EVO (minus the ABS and all that fancy shit)

[He Man]

ah why the hell not, a little preview from the rear.

[koko64]

The evo has hotter cams (you won't have to buy DP cams), higher compression and more capacity (you won't have to buy hi comp, big bore pistons or rebore/replate your cylinders) and better ports (no need for porting really). So one way of looking at it is you got a bargain. Imagine what all those mods would cost on your DS motor?

Use the DS airbox with open lid, fancy filter and fueling mods and you might get 100 hp.

[He Man]

are we talking about RWHP or crank hp?

100hp isnt much of a difference from the 95hp fo the DS1000 if its crank. I was getting 83rwhp on my DS1000 motor. Im hoping i can break 87hp with the 1100 EVO.

I'm going to keep the airbox and take off the top of the lid, then slot the sides so i can mount an aluminum plate ontop with some sound deafening foam. Hopefully it will be like an open airbox, but the plate and foam will help deaden the sound (like that filter) and give me space to mount stuff.

I was talking rwhp. I know Ducati have been quoting crank hp like other manufacturers. The 83 hp was SAE hp and with pods I bet.

On paper, the evo motor has been tuned to increase peak hp, but looks to be particularly well strangled in the US. The motor, on paper looks to have all the ingredients involed in getting the newer big valve desmodues towards 100 hp at the wheel. The fueling and intake appear to be a significant bottleneck.

Its well documented that they run lean as hell, but it seems that the airbox design has been affected by packaging constraints. I would let the airbox be open with a K&N or similar  filter and get a Shorai battery to solve the ignition packaging.

Maybe a PCV and reflash to start with, or ever considered an Ignijet system? I know you are wanting to keep costs within sight. Brad might know if the DS spark map will suffice for the evo with its compression/capacity increase if you used premium fuel to at least get it running to test and tune.
How confident is your local dyno guy of being able to remap for the evo motor with the devices available? There is the premium Ungeheuer option, but maybe a PCV/reflash with premium fuel could get the ball rolling. What mapping did your bike previously have?

I havent touched an evo motor, only been amazed how crammed it is under the tank.
I would email Brad Black and Speeddog, etc.

Travman's 1123 DS makes 95 rwhp and 82 ft/lbs with stock cams. Iim pretty sure hes running an open airbox with mapped injection. His bike has a PCIII, but the general ignition timing numbers could be useful since his bike has similar displacement and high compression.
I don't know if he's using the stock ignition map, a custom map or just knocked off peak advance. His bike has stock DS cams, it's a grunter.
I would contact him regarding mapping.

does anyone think the exhaust fight might be able to squeeze in that spot on the trellis frame? i think it ight be too tight but it could just be enough to squeeze in there.

Not sure the evo stock would work
try to see if an s2r would work if u got it

[He Man]

mine works. its mounted up if u look at the pic above. the only difference is that i need to a steel tab to hook the udder up to engine to reduce the stress on the other mounts since they are so far away.

i just like the routing of the EVO exhaust.

[Raux]

Hell try it

more pics of this please?

GO HEMAN GO.....there are people watching with intense interest!!!

[He Man]

Im sure there are people who just want oodles of pictures. But i holding out on u guys on purpose. Itll be better when i do a full write up.

anyway... theres only 6 items left to do.

1) relocate teh starter relay and make a longer starter cable to reach.
2) Splice the oil temp sensor wire.
3) Change the valve cover and install the oil cooler
4) install the 848EVO pickup sensor once it arrives
5) Install acoustic foam on airbox cover.
6) reconnect the alternator wire to the rectifyer.
7) rebuild the HID wiring harness
Install these FIAM dual tone horns


Somethings that will need to be done soon
1) replace teh left tach lens since i cracked it somehow.
2) install an auxillary fog light
3) make a proper airbox.
4) get right angle boots for the spark plug wires.


This is teh cut airbox. there slots in it because i used to run the wires under the cover for the ballast. I didnt have a hot knife and my buzz saw blew up, so i had to use a metal cutting disc to do this, hence the dirty cuts. Its only there to get the tune, there is defintely more open urface area than just a cut top, though it doesnt matter since the whole filter is expoed already. There will be acoustic foam on the underside of the metal plate (shown later). Im going to weld up an aluminum bracket later since i hate how ghetto this looks, or maybe even do a fiberglass mold. this thing weighs a ton.



also had to make a rear plate, because the old one was ugly.


Yes the fasteners are rusty and whatever. i dont care. i just want to ride.


its almost done. It took me 3 hours to route those wires so nothing is going to be ziptied to the frame. and most of the wires are hidden.  You can see the ballast sitting on top of its new home. I driled 2 holes and im jsut going to ziptie the ballast.


oh and i have some tapered bearings on that sucker. the install was a pregnant dog for the lower bearing since i didnt have a proper install tool.

[koko64]

Looking forward to seeing how she goes with a tune. I bet that airbox works better than the pods you were running. That plate on top looks like it should help dampen the noise.  The plate looks high enough off the filter to let plenty of air in. It actually looks kinda high performance with the plate!

[thought]

I have to say I'm really impressed by how fast you're getting this project together 

get that write up up, this is awesome.

I have the HTM1100S lightweight drilled starter gear for sale if you are interested
