Default 06 S281E Twincharged

Hello,

I have an 06 S281E with an exile twin turbo kit. I still have the Saleen supercharger. I have done a ton of mods to the car but most of everything was done in 2010. Looking to reboot the car. Could someone please remind me the stock compression ratio (9:8:1?) and stock blower pulley size and boost (12 lbs?) Did the 06 extreme cars come with ported cylinder heads and custom cams? It’s been so long I just forgot most of the details.

Extreme cars did come with ported cylinder heads and cams. Did you buy the tungsten silver extreme that was in the Chicago area?

I actually bought the car new in 06....did all the bolt ons in 08....then did the twin turbos in 2010.

Are you sure about the heads and cams? From what I have read so far it appears the 08 Extremes had heads/cams. Hence the 620 power rating with the 5.0 block.

Spec sheet only shows ported aluminum heads. No mention of camshafts being changed. 08 extreme spec sheet shows 5 axis porting and custom camshaft.

I would love to pick your brain. I have a similar setup that I am getting ready to drop in a car. Aluminum 5.4l with Saleen S331 supercharger and an ON3 twin turbo setup designed for the GT500.
