VAC 1.05

[dwilfong]

After over a year of planing and lot of measuring to see if it would work its all most ready.

Got my VAC 91 case bored by Steve Wood and the small end of the rod honed out .008 after the bushing was removed and it all fit together. installed the RS1.01 P/L and wrist pin and it all worked nice. the transfer ports lined up perfect and the exhaust. Just need to raise the boost port in the case a little.

Just ran the numbers and it is perfect.130 trans and 190 ex.

Now just have to port the case, make a brass button and cooling head.

Steve thanks for the great work. it was all worth it I knew it would work.

Baby steps 190 is good to start.

It very well might go BOOM but you don't know if you don't try.

All tho it will have a 30% billet piston in it. the deck hight on the piston is .020 taller than stock piston so the numbers can be made lower than 130 -190 with this piston.

Just have to scratch my a$$ and come up with a good starting point.

Just pokin' fun Dave. My biggest concerns would be the crankpin and bearings.

Thy got one just need to see if it holds up to Gas first before we slap the nitro to it. :lol:

Harry's got one I will see how it runs at the pond. when he gets frustrated with it I will bend his ear till he says uncle.

Those guys get real humble when I test run Brutus. 95MPH top end diving in full rudder turns at 76MPH hook up tight last weekend stock 2818 at 24000RPM.
