    So-Called "Performance Chips"

    Has anyone purchased and installed a performance chip that really works for the Northstar in the '93?

    They won't give you much or if any extra performance. If you're looking for a few extra horses, the most bang for the buck will come from an aftermarket exhaust system such as Corsa. The other thing I also know is that installing a higher stall torque converter for your transmission will also help. You want something around the 3000 rpm stall range. You can go higher like 3600 rpm stall for even more performance but it would ruin your car street driveability. Then of course there are other things that'll give you 1 or 2 horsepower here and there such as porting the throttle body, porting the heads and installing gapless cylinder rings. However, you can also loose horsepower with modifications such as aftermarket intakes which our Cadillacs seem to always hate.

    as Ed stated, allowing the engine to BREATH (exhaust / intake) better is the simplest form to get hp. not after market parts.

    all that Ed stated and also trow in a K&N filter. the difference from a paper filter is significant, more than you will ever see from some chip that changes timing.

    we have a '93 that had most of that done and is said to be kicking around 350hp.

    Did all this inquiry when I had my Fiero GT V/6. Horsepower is wide open throttle, where most of us never go. Torque is what you can try to improve. Most times improving torque is not at the expense of lesser mileage whereas HP increases can affect MPG. I would investigate what changes were made by GM 2 or 3 years down the road on the Northstar to raise performance.

    Horsepower on the Northstar went from 295 hp in 93-94 to 300 hp for the newer years. The extra 5 hp is attributed to a different intake manifold design.
