its cool. i'm not trying to sell it to ya...

just sharing my experiences

 

LOL. I dont think there is much of a spool difference on the .48 and .63 ar. But I think using a .48 housing on a GSR would become restrictive in the top end.

 

so why is my buddies both with sc61's with .63 a/r spool up much later than me.. see you guys keep saying you THINK it would be restrictive , but I know it wasn't on mine.. dyno sheets to prove it and tony1 agree after he tuned it!

do you see restriction from the dyno, its pulling up all the way to redline.. over stock redline actually!

you guys think everyone on here is shooting for high hp numbers... not everyone wants 500whp. some people are happy with 250-300whp... i'm not but lots of people are.

 

yea thats fine and dandy, but u try doing that **** on a BUILT motor and more psi, then shows us a dyno sheet, show us where its starts falling just my .02, i rather have a **** load of top end instead of quick spool then getting passed up, and i can understand why u dont have that much back pressure since your running open down pipe, were not saying its not gonna work for a person that just wants like 3xxhp, if thats all u plan on going and never gonna up the boost, **** stick with it then, if it works for you, more power to you,keep using it, but were just telling the OP that if he EVER wants to upgrade that its better to get something a bit bigger

we are talking about a STOCK GSR .... that is all

this dude doesn't sound like he's planning on upgrading anytime soon, and exhaust housings aren't expensive

yes a smaller .48 might choke up, but for the STOCK gsr , a medium good sized .48 turbo would do just fine...
