    You must have a lot of faith in SLP! That must be the most efficient automatic ever!

    Depends on what kind of dyno and what shape the car is in, 300 would be my guess.

    No disrespect to anyone, but there is about .000000001% chance of that happening.

    Let's do the math..325Hp to start at the crank. A typical loss of 50 HP for a manual trans, a little more for a auto to the rear wheels. So for the sake of argueing, let's say you're starting with 270RWHP. Okay, let's add up the goodies now: SLP Lid (I did the whole cold air system, so I'll assume you did too) add 8 HP, forget what they say. Smooth bellow: add 2HP at best (don't get mad at me, I bought one too) TB by-pass add zero HP. My best RWHP guess:...280RWHP If SLP could get sued for inflationary advertising, they'd be out of business. But, they do make a quality product, and in spite of the fact that I do know they inflate their claims, I purchase their products almost exclusively for my Camaro too. make sure you have quality gas in your car for the pull. It does make a differance!

    In case you thought I forgot about the Flowmaster, I didn't...the average Flowmaster owner LOSES 2HP...Sorry and yes, before I did redid my entire exhaust system, I had one of those too.

    Okay my estimates may be a little on the high side. After thoughtful consideration I will revise my guesses to be 315 at the wheels and 346 at the flywheel.

    If you guessing 315 at the wheels the flywheel would be more like 370ish.
