EFI Bighorn

[Uniflow]

 There is a video of the Bighorn on the dyno coming up soon, it's somewhat more " uncivilized "

The new engine is going to have to put out 65 or more (Crank HP), I want more than any 450F can muster!

This Bighorn has very old cylinder Tec on it I haven't done anything to the ports apart from cleaning the burs around the transfers and raising the barrel a bit. And widening the exhaust a bit.

40+ HP on that bighorn? That is pretty darn impressive. I would be surprised if my RT3 made more than 25.

These injector projects of yours are just so impressive, Thanks for doing this and posting your work and results!

An update, this was posted elsewhere on TSM but I thought it might be better here.
