Has anyone who has ported their '03 S/C had any NEW problems?

How many miles sice it was done?

Also, what were your hp/tq gains?

I apologize if there is already a thread out there on this?

 

[SoCalBlk03]

1. No problems
2. approx 20000 miles
3. Dunno, did it at the same time as my TB and a few other things. But my cars last tune put down 498-508 RWHP/ 501-512 RWQ SAE depending on which smoothing you use.

It caused my tires to go bad sooner ...;-) :burnout: :burnout:

 

[maoun]

some reported problems include: a lighter wallet

 

[sambandit]

Dude, porting has only been happening for a couple weeks. It will be awhile before any problems arise, if any. Can't see any in the future myself.

I think a little longer than a couple of weeks, but your point is taken. SoCalBlk03 said he has had his for 20k (first reply), though. Also, it might only take a few days to figure out if you have a stall problem after the porting but not before. Thanks for the feedback.

anybody tried porting their own SC?

I have to add 3 90mm Metco Idlers now because I am over spinning the belt if I get on it over 4000rpms in 1st, 2nd or 3rd

Just to let you know griffin, replacing the other 3 idlers with Metco 90mm wont help because those are the same as stock sizes. Stock ones are 3 1/2 inches which is either 90 or 92mm, cant remember. I think I remember from the other thread you said you were holding your boost or onlt loosing a pound. That is excellent!! Most of us loose 2 to 3 lbs.

 

[Griffin]

Sam,

I can only hold boost if I hit it under 3500rpms in 1-2-3rd. Anything higher and I overspin and loose boost I think I might have to go back to the 2.84 I had on for more tention on the belt. And I am back to 14psi. The rise in boost was caused by the cold weather down here

:beer:

 

[sambandit]

Yeah, I've been fighting boost drop off forever now! Some folks say they hold boost and loose none but it remains to be seen! Can't wait to get my ported blower on!!

 

[trey193]

Every 03 I have rode in with a smaller pulley has lost 1-3lb's of boost , my car makes right at 14 and falls back to high 12's to 13 @ redline, until someone makes a vid of a full throttle pull to redline with a good guage I wont beleive it when they say they hold boost to redline!

 

[plan b]

Get the Billetflow 4 idler setup, looks the best IMO and gets the job done.;-)

Couldn't have said it better myself! I only loose 2 with a upper/lower combo which I think is pretty good.

I agree also guys, that doesn't make sense Griffin.

When i was at the dyno today we checked to see if i picked up any more boost with the ported blower and my car still made 14 pounds of boost then dropped to 12.5 pounds at 6300rpms which i thought was not bad.

What were your before and after porting #'s??

 

[Griffin]

Maybe my boost gauge isn't working:dw:

I know when I dynoed yesterday I had the guy check and it held until redline.:shrug:
