Thunder "Big Bore" Kit

[Myklops]

Sorry for waking this thread from the dead, but am I reading this dyno sheet on Thunder Mfg's website correct? An additional 25hp and 17ft/lbs of torque? Good. God.

Hopefully someone will offer a bolt on system with all the bugs worked out

I've toyed with the idea of adding a fairly small (K03) turbo on the Vulcan but that requires a lot of custom fab work and a piggyback fuel management system like Megasquirt.

If you're looking at the kit for the 1700's believe it. That's my bike. They used my Vaquero to do the development on the kit. It is amazing! It makes incredible power, but is still completely comfortable on the street. It even gets better mpg at 70-80 mph. If you want to do any of the kit, You really need to do a port and valve job to get the most out of it.

If you want more info, feel free to PM me.

Scott did this to a 99 Nomad and it would keep up with his V2K. But there was as much money and effort in doing the heads as was involved in the big bore kit.

Cams and headwork will deliver more seat of the pants response than adding 100cc.

Scott "Hotsausce" build his Nomad way before there was a V2K. He told me that he was disappointed after trading off that Nomad for the V2K until he put the Euro gears or whatever into the V2K.
