ported blower?
 

ok seems how im not driving my balt im thinking of pulling the charger. Porting the blower and pluging the silencer holes. im wondering do i have to get another tune after i port the blower? MORE AIR+SAME FUEL=LEAN=BOOOOOOOOOOOOM

bump help please

you dont have to do anything, but it is recommended since these cars are soooo touchy

no...its fine. It doesnt really increase the amount of air, just removes a restriction in the outlet side so the air doesnt get compressed as much. But the number of air molecules will remain the same

while were on this subject what exactly does porting it do as far as performance?

..didnt i just say what it does? ^^ lol. It doesnt do a lot in the way of performance. An intake will probably post better gains, but porting it makes the SC sound pretty nice.

better tune for it. Trust me on that one. and it moves a bit more air than you think.

if it moves more air then it does have performance gains.....

i didnt say there werent any gains, im just saying porting will not yield a large power gain. its similar to running an intake...not a huge boost in power, but noticeable. And ralliartist, I know how much it improves...mine is ported :)

intakes can add 15hp 15 tq. thats a good performance gain. how much does it cost to port you blower. thats what makes it a good gain or not.

i cant really say porting the blower was noticeable performance wise for me. and i had it done right after stage 1

sounds nice thou

i'm not exactly sure about the tuning, but i'm hear to drop a little info to the OP.

if you want someone to do a really good job of porting your s/c..... then get ahold of OTTP, they only charge like $250. you send them your s/c, they hook it up and send it back. a friend of mine just had his done from them and it looks amazing. he is about to install it

A member Euthanasia on here ported my supercharger and TB for $60. I was part of a group deal thoguh. He normally charges i think $200. Its a great port job that rivals most professional jobs (he's been working on cars his whole life). He can port the blower, port the TB, plug the silencer holes, polish the blower...etc. Everything you could want, and any combination of the above.

My blower is ported and I believe it adds a few whp and wtq and lowers iat's by a few degrees if I'm not mistaken. Not a bad mod. I love mine :)

better cooling.. i put my hand on it after 5 dyno pulls and i could hold my hand on it... i did that with mine (not ported) and burnt the shit out of my hand

polished aswell

look so nice if done right

how big are you guys porting the outlet? ie: how much metal are you shaving off? 1mm? 2mm? more?

I think its 1-1.5mm on each side... ive heard doing it too much can actually cause you to lose efficiency.

i meant to say 2 - 2.5
