75-100 over the stock power???.If you want to go bottom then you should get the SPA manifold ,I found it on ebay for 550 shipped,it's good for close to 500 at the wheels on a s52.Or you can try the treadstone replica,it's a lot cheaper but I do not have to much information about how it performs or how long will last.
