    Well if you were hoping to go pick up your girlfriend, it'd definitely be a good thing!

    The stock air cleaner is in front of the radiator shroud which directs hot air back over the engine.The only time air from the radiator can get to the cleaner is when you are still.Once moving outside air comes up to the air cleaner.The hot air from the radiator does not do a 180 turn and go out the front of the engine bay.

    LT1 exh is better than L98
    Do the LT's and Y pipe at least , you can always change the cat back later.

    Default Dyno

    I have to call back Friday to see if I can make three pulls on Saturday and then see what the next modification will be. I am going to Welcome to Anderson Performance Automotive! , check out their web site, they have a buick grand national going 7.25. WOW! If they can get me in Saturday, I will post my RWHP for all the world (CAC) to see. I just hope I am not too disappointed with the numbers. If I have 300 RWHP I will be happy. What do you think. I know I have a lot of front end mods and nothing aft but something is better then nothing. The front end stuff is easier for me to do because I don't have a lift. What do you think I should spend on an exhaust system?

    Default DYNO RESULTS

    OK people, I ran my car on the dyno today (4/4/09) with the following results from the two pulls:
    Dyno Run 1 - Max Power = 233.12 rwhp, Max Torque = 300.76
    Dyno Run 2 - Max Power = 236.09 rwhp, Max Torque = 297.84
    It just goes to show you that the numbers posted by manufacturers for bolt on parts can not be believed. From all my bolt ons, if I use the low side number, I should have gained 170 horsepower. Using the GM base 245 fwhp for my car and a calculated 283 fwhp (dyno 236+20%), I only gained 38 horsepower, which is 22% of what the wonderful bolt on manufacturers claimed. I knew the claimed horsepower gains from the bolt ons were too good to be true but I thought I would have gained more then 38 horsepower. Unless my starting horsepower was less then 245, then I gained more but I didn't dyno before doing all my mods. At least going forward I will know my gains. Don't assume or guess your HP, find an affordable shop to run it on a dyno. I paid $75 for 2 runs.
    I would like to thank everybody for their feedback on my thread.

    Another name for a dyno is ego buster.

    I was at a dyno day and they ask everyone what their power would be before they run it on the dyno and nearly everyone guessed way too high.

I do plan on doing the exhaust but I am not sure what to do, the Cat Back or go for Long Tube Headers, eliminate the cats and go dual out the back. I do like the torque but I also what some top end. I am so confused and I just want to do the right thing when I drop another 2-3k into the car. What is your opinion on the exhaust???
    Thanks for the feedback.
    Lee
    50 horsepower is quite a hopeful thought. The only way you could have a chance for such horsepower gains is if that exhaust system includes full length headers.

    You need to get a copy of Desktop Dyno. It gives the most accurate calculations this side of an engine dyno.
