What is a miniram i am new to F-bodies and never heard of a miniram? Sorry that i am so stupid but my IQ may go up knowing this!

 

now ive never seen one but i think it looks like an LT1 intake but flows better.

It is an aftermarket replacement for the TPI. You can see it at www.tpis.com. It does look like a LT1 and flows similarly, but has a place for the thermostat and distributor. I am guess you are not yet prepared for a discussion of short vs long runner length and peak torque yadda yadda yadda. When you are do a search on the Miniram (in the forum) and you will find more info than you can handle.

 

in short..
long runner length (stock TPI) allows (forces) the peak torque at a lower rpm and so a shorter length (LT1 Miniram) allows (forces) the peak torque at a higher rpm.
it has to do with when the valve closes it makes a compression wave that travels up to the plenum (place before the runners) and then the wave travels back down. the longer the tube the longer the wave has to travel, and since the wave travels at approximately the same speed no matter what intake you use, the long runners take more time for the wave to travel thus needing more time between valve openings (low rpm) to let the wave help "push" more air into the intake. short runner does not need much time so it needs a less time (more rpm) between valve openings.
if i miss typed or said something wrong please correct me anyone but i think i at least got the jist of it all

Allmost, but the "short LT1 runners" are made to not tune the Rane for anyt rpm, but tune for ocverall performance. The ls1 is tuned for upper rpm use, but the miniram is made for over all flat torque. If you use a cam that picks up at 3000rpm and runs to 6000 Rpm then the Miniram is the choice.
