i always chase more torque .. low to midrange is the best as were you use it the most... but gaining BHP also helps... mild reprofiling cams wont make drastic changes just help a little.
ported heads, manifolds etc again aid airflow and increase torque and bhp
raised compression again more power albeit very small amount considering only raising to 10.8/11.1 depending on what i feel like
none of mods will drastically loose low end power yes will obvioulsly move slightly by product of tuning unless cc increase or using forced indcution but be ok
as said if can get another 40bhp (peak) that means through out rev range should increase power leading up to peak outputs.
for troque n/a cc is king. hence a tuned 2.5 as stated can put out 200bhp but still wont feel as torquey as a 3.0 becuase it isnt.. the torque peak be higher and more peaky.
would be great if could get oversized pistons for 3.2 and get to 3.3/3.4... who knows maybe further down road something to look at hahaha
apologies on later vecs running 4xA Cams cheers for correcting
you want to start with the best cams you can for regrinding as the profiles are all slightly different. so sending j instead of a cams may yeild a slightly different re profile shape due to the original shape.
Just a thought. Any benefit in changing the pistons?
The 3.2 ones have indentations in the crowns to reduce compression .... (part of the green save the trees brigade etc)
ive not mentioned pistons not sure what your actually asking.. i already have 3.2
