Bolt on Weekend power tips
 

What are best bolt on type of HP setups for a GT. Have Mac cold air induction and performance exhaust.

Need recommendation for aluminum und pulleys and throttle body? what the average hp gain for these? Is it worth getting them installed by prof or can I do it myself?

thx...

underdrive pullies and TB will give you about 30 hp so they say. It is very easy to do your self. You should not pay anyone.

30 HP from just pulleys and a TB? Not on a basically stock motor! The pulleys will give like maybe 8 to 10 if your lucky. A TB will maybe give a few HP, but the air flow is still going to be restricted with once the air hits the smaller inlet port on the intake.

change the gears..although it want increase HP ,you will notice a big diff. in acceleration

Get a C&L Mass Air Sensor. Bolts on in less than 30 minutes. Good for 10 - 15 HP. I have one and swear by it.
