So far I added the Black Wing, ported TB, long tube headers, Corsa X pipe on to pace car version of Corsa mufflers, and of course our local tuner has it set up. On a Mustang dyno rwhp is 325. My tuner says he sees signs of detention, so the timing is set back a bit. Here's the guestion: I want to add a supercharger, probably an A&A Vortech. Given the stock compression of 10:1 and the need for lower compression with super charging and already a need to set timing back, will adding the Vortech require the timing to be retarded so much I end up with no real benefit? There's a really good chance that I am confused about how these thing work, to most any guidance will be appreciated.
Thanks

You will see significant power increases from a properly installed and tuned forced induction system. There is a forum section dedicated to discussions on supercharging (C5 FI/Nitrous). Check it out - much good info there !

go to the Procharger website and order one of their thick, free, beautiful catalogs...you can learn a ton from it and drool over the products and the Corvettes....

Hi there! Like CHJ stated... Go to the FI/Nitrous section and repost this... You will no doubt get great responses if folks like Arun or Bret pop in... ECS guys too.. Just a ton of folks over there in that section that have had every scenario possible arise with F/I... Good luck and I hope they tell you pull the trigger!

Investment in a S/C will bring significant HP increases - just be sure you get the parts and service from a very reputable installer. There are a number here on the forum, including ECS.
When I bought my '02 the previous owner ( a CF member) had a Vortec V-2 installed. The work was done by Motor Sports Image in Roseville CA.
From what I read in the install manual, it takes a good 30 hours worth of labor for the entire project. The Vortec V-2 came with a SuperChips tune that required some coordination with SuperChips to build the tune, install it in their reader and then have it installed in the car's ECM. I would think that just about any S/C package will require a tune and be done thru the ECM.
This particular install used 42 lb injectors, a water intercooler, and it required that the alternator be moved to the passenger side of the car. The air intake is a Breathless Performance unit. The exhaust is a cat-back Corsa Indy system with an X-pipe and retained the stock exhaust manifolds. Boost is limited to 7psi which is fine for the stock compression ratio.
Once installed, the car dyno'd at 443 RWHP and 402 ft-lbs at the wheels. It idles like a stocker and I have seen real-world 32MPG on a 500 mile trip at between 75 and 80 in 6th gear (figured by hand and not from the DIC).
This is an old pic, but it gives you an idea what a Vortec install looks like.
The detonation your guy thinks he heard could be nothing more than carbon build up which is common and easily corrected with Sea Foam. Another cause could be oil getting in to intake - also an easy fix with a catch can. Neither of these is any reason not to take care of those minor issues and go FI.
