Reading the last few responses confirms that my particular combo leaves a little bit to be desired. I often feel like the car should have been faster than 12.0 in the 1/4. It was mainly run in the 1/8 mi. so it may have been running out of breath with the 4.30s. It's a basic, no frills Duster though, couldn't have weighed much over 3,300. Really should have been mid-11s at least. QUOTE]
I was wondering the same thing why your combo wasn't fastener than that. It sounds like a real healthy setup that should be in the mid to low 11's I would think. I will say you'd probably benefit from a 950HP or something over the 750. I run a 950HP that around town and it performs really well.
To the OP, I have worked W2's and they do make some great power. I have no comparisons or dyno sheets to go off of though. But like others have stated, you need to port them to really wake them up and get the full potential. Old design but it's a good one.
