Slant 6 Turbo 68Dart Project
I like you thinking :)
I figured that was what I would be in for. I guess I'll get to ordering.
On the Weisco spec sheet it says I would get about 10.5:1 did you do anything else to lower compression, like a spacer?
I have no spacer, and only a .040"-thick head gasket. Measured that with a burette and colored water, it came out exactly 9:1, and I was careful. My cylinder head has never been milled, nor has the block had any material removed from its sealing surface.
I don't know where Wiseco gets their figures (you'd THINK they'd be accurate with this,) but, I re-checked mine several times and it
is an actual 9:1.
Works well.... at 15 pounds of boost.... soon to be 20, then 25 if I don't blow it up...
Goes 12-flat on racing gas, with a Snowperformance BoostCooler using pure methanol... no water. A/F ratio is 11.4 under boost conditions. Fat, but safe...
It weighs 2,680 with no driver and has a 2.76:1 final drive with a spool. Research has proven that deeper gears always go slower, hence, the strange ring and pinion gear ratio. The slicks are some 9"-wide Hoosiers that are 26"-tall.
I rented an ISKY O-Ring cutter and installed the (supplied) copper O-Rings... I don't know what that might have done to my compression ratio...:oops: It was done after the compression ratio was calculated (measured.)
