How much Boost to run on stock bottomend

Bigb2000GT · April 29th, 2007, 11:41 AM

Well decided im getting a brand new 2004 engine installed at local dealership 3yr 36k warranty and was gonna order a kenne bell 2.1 charger as it looks should have them both by july just what is safe with good tune for daily driven car with stock bottom end is 9-10psi too much? I want this setup to last me a lil while was hoping to run somewhere near 400-420wph on stock engine. My setup would be full exhaust with 75mm TB and KB 2.1 @ 9-10psi would this obtain my goal? and would it be safe for daily driver? My optimum goal is a low 12 sec street car.

9-10 psi is about where everybody says you shouldnt go any higher. But I am almost postive that the warrenty on the engine will be void if you put a KB on it. And yes that is a nice safe street car, but you will need suffeicent fuel for it!

Yeah I understand about the warranty being voided with KB thats why im keeping stock intake TB and plenum and injectors so just in case something happens I make the swap and then take the supercharger myth with me to my grave

Worked before when I ran Nitrous on my camaro had aftermarket lid that I tapped hole for nitrous line blew the intake manifold to pieces, so I removed all lines and put the stock lid back on some how I got away with it and the dealership replaced it but after I got the car back I opened up my glove box and my dumbass left the Nitrous button hooked up and in the glove box plain as day too I know the GM techs had to have seen it they just didnt care.

9# is as high as I would take it with a KB...

9 psi with a kb is what I'm running. You should hit your goal of 400-420 rwhp with it. Everything I read about the KB on their site says it can't void your warranty, but good luck telling that to ford.

Oh yeah. MAKE SURE YOU CHANGE YOUR PLUGS! lol
