Are low Compression pistons a must when having a SC?

..............?

[Dark_5.0]

no, the 9 to 1 pistons that come stock in a stang do fine. you really dont wanna go over 9.5 to 1 though.

what sort of combo and boost are you going to run. The biggest problem with a higher compression boosted motor is the tunability. It takes more effort to keep the internals from taking on damage with a higher compression motor.

im not sure yet, i just started looking into all of this. Do you Recommend anything?

[procharge94]

Well, the stock bottom end of a mustang can easily hold over 500rwhp. Just check out Darius's black fox. If I can ever get my injector situation under control, I will be mounting my blower, using stock internals.

As for your motor combo.................HA, thats a loaded question. Is this your daily driver and do you plan on putting the car on the track (drag strip, road course, etc)?

[9TOFIVER]

yeah as of now its a daily driver, and yes i do plan on taking it to the track one of these days.

[procharge94]

Well, the 'one of these days' statement is not really specific enough. If its your daily driver and you don't plan to go balls to the wall race with it; the stock internals will be more than adequate. I would simply suggest a good tune with a chip from your local dyno shop.

The world of motor bolts ons is far too vast for me to make any suggestions without you coming up with some examples of what you may want to run........

right now im running a Cobra upper Lower intake,73 MM throttle bodie, bbk CA intake, Under drive pulleys,Msd Ignition, Gt40 Heads , ford racing performace chip,and 28 lb injectors, now im sure im running high 12s right now, i want to bring it down to a satisfying 10, then as i meant in "one of these days" which i was wrong for not writing a full description on, is once i get another vehicle , i plan on starting all over on the engine and making it something of a daily strip rider, but for right now, just a nice punch to a daily driver will do. Thank for your responses brotha, appericate the patience.

So basically, you are going to use the blower to bring down your track time? That makes sense. I would still recommend having a shop dyno tune the car, especially since you want to start running some competitive times. Having your car dyno-tuned will help find and make the most use of any extra horsepower and torque that a simple "butt dyno" would most certainly miss.

So, to sum everything up, your current compression with your current internals will be just fine. As you said, you plan to pull the motor apart once you have another daily driver; so just wait until then.

P.S. - traction is going to be your ticket to running 10's once you have the boosted power. High amounts of horsepower will do very little if you cannot get that power to the ground. Have you already made provisions for this?
