thanks one_and_only2004, really appreciate it. klampy, i might just take you up on that offer, but for now, in your oppinion what are the best mods to make power form the ECOTEC v6?
anyone elso with any information you think might help me, please feel free to reply
well in my particular application (puts on fire suit in preparation to get flamed)its a VS V6. iv put a tiny little turbo on my stock, but freshly rebuilt motor. its being built as a tow car for my drift car. all im doing is putting a T25 turbo on one bank of the engine (its not the "proper" way hence the fire suit) to run boost low in the rev range purely to help make torque for pulling power. in this application im not aiming for top high rev power but more drivability and hopefully to a degree, better fuel economy.
so my setup will run approx 10psi of boost from about 2200rpm up to about 3500-4000rpm and start running out of puff after that. i dont really want any more than that for need to go with bigger parts to reliably achieve more
so the car already has a 2.5 cat back exhaust, iv got a MACE 12mm manifold spacer to lengthen the runners to help with lower rev torque and response, and i plan on a custom plenum lid to *1 increase plenum volume and *2 shift the throttle body to the other side of the engine for shorter intake piping.
but in a stock application, first mods are usually i cold air intake (CAI) to improve the temp of the air = more oxygen =more bang = more power
a higher flow filter to decrease intake restriction
then the exhaust normally a 2.5 cat back, or full system with tuned length extractor pipes to help draw the exhaust out of the heads and also create a scavanging effect during cam overlap to help draw more air on the intake stroke also.
beyond that, theres cams to change the attitude of the power delivery, port work to speed up/or slow down and to increase/decrease air volume available to the cylinders.
bigger (stroked) crankshafts to create a larger capacity engine by increasing the swept arc of the crank therfore putting more torque into the turning force of the up and down motion of the pistons.(which is also increased)
im sure theres tons more but mechanically there the most common mods that people do.
