And here's that weird spring deal I was talking about it is fully self mechanical opens with flow the more the wider it goes. I would imagine this is for some added back pressure and for the exhaust braking aid when slowing down.


These changes have been on there since about two weeks after we got the car.

That's interesting, I've never seen anything like it.

Just enough clearance for belt too. This setup is not slipping and is getting me a solid 8-10 instantly rising to 12 very fast and holding there. Blow off valve is still big enough too lol. Sunday funday will be doing some logs. The AFR is holding 11.5 until 4500 then climbs to 10.8 ish nice and safe for a little warmer air. Will add the meth back once I have my tb and boost pipe shortened up here soon enough all in all good deal. Neil thank you for the pulley it will get a lot of use. May also be doing impellar upgrade soon of funds allow that should put me in the 14-16 range which is all my 7rib setup will be able to handle before slippage. 2015 is gonna be fun "LETS GO RACING BOYS" 11s are mine.
