Message: <blockquote data-quote="-e f i n i-" data-source="post: 812916" data-attributes="member: 7258">Time to revive a dead but informative topic.Actually i was gonna ask you more questions on superchargers. been really curious and theres this urge to know the answer.... but after reading what you said...... i suddenly cringe in fear... but i'll try to quench my curiosity anyway.So OEM Toyota superchargers really can't add more power?Can the SC14 bearing be changed for higher SC speeds?Supercharger pulleys doesn't control boost right? Because if it just spin and spin and spin, how does it regulate boost pressure?? But whats that pressure rating as advertised on supercharger pulleys? Like Pulley A, 15psi. What does that mean?If you wanna squeeze every bit of power out of your supercharged engine, is it wise to use a smaller pulley? This is what I think and synchron, I'll leave you to judge whether what i have in my mind now is true. Okay here it goes, when using a smaller pulley, max boost will come in later, as the supercharger is also spinning slower.And since higher duration cams can be used on supercharged engines, and the higher the duration and lift, the later peak power will come in but usually in a larger number, if we can make the max boost come in later like say 8000 or 10000RPM, we can make more power out of it.is my theory true? This theory is based on the combination of NA tuning but a little of forced fed tuning.But if we make boost come in so late like in the scenario given, wouldnt it be equal to a large sized turbo response or worse?but since u said SC14 cant take any more than 9K sc speed... erh, does 1rpm engine speed translate to 1 or higher rpm SC speed depending on the pulley size?I forgot already but i think u told me this once, roots type doesnt require a step up gearbox as it is pumping air in faster than a centrifugal, right?I kinda dig superchargers, but the price is a bit expensive...like what u said last time, if i dont have RM10K in hand, i better not play SC.Oh yeah, this is also something that is bothering me for quite awhile, say we use W55 gearbox, how bout the other drivetrain bits? rear axle and all those? can we use the whole drivetrain system from the 1G Supra models? I dont think Silvia drivetrain can be fitted... for waht reason, i dunno...Okay enuf stupid questions for the day.^_^</blockquote>

Another advice thread.

Hi guys, I've just got my licence and was thinking of getting a S15.I was thinking of a Miata, but the boot space was too small.

Is 70++k for a almost 80k km S15 a good deal?

Using stock turbo, when does it...
