Heh. That SC61 will not get even halfway efficient until about 4700rpms, and will not get efficient well at all until you work on the LS head a bit. Remember, you only have 7000 rpms to work with. And a bit more stroke. What are you trying to accomplish in this setup?

how are you getting spool at 2700?? im running the same turbo and even in 5th gear i dont start to spool until over 3k, and its closer to 3500 in like 3 and 4th gear.

that turbo is good for a decent chunk over 400hp, how much power are you making now?

Im running the same size turbo on my B20 and I dont reach full boost until about 4k eathier. How in the world are you getting full boost @ 2700? Are you sure that your tach isnt off or something? How many lbs of boost are you running? Something doesnt sound right.

he said hes running EL mani + 3"dp so it spools up sooner than the cast mani w/ 2.5" dp ..less restriction = quicker spool

I'm running a 14b

It will start spooling the second I floor it. And even under normal driving conditions.

I'm running an open 2.5" dp. And surprisingly it will hold a solid 8psi from the time it hits till redline.
