-which is better?
-what times have you guys run with these blowers

thanks

 

LJ's run 9.9x at 139.x with an S-trim.

 

well i destroyed my built tranny after running the car for maybe 5 min with a p600b. car didnt even hook. so it might be puttin down a little power

 

you guys running ic's

 

Procharger is the only way to go.

 

vortech all the way...

 

I like my p600b..

my friend has the same setup as me...

355ci Lt1 ...same bottom end...but he has CNC heads,mine are hand ported..
he has a .510/.510 lift cam..and I run the hot cam..he runs 10psi from his S-trim..I was running 6psi last time we ran.....and I yoinked him hard..I have a vid of it somewhere..

 

I saw a test about 8 years ago comparing a 6 psi S-trim to a 9 psi intercooled P-600B. The 9 psi blower took more hp to drive it and it heated the air more. By the time you factor in the losses through the intercooler and the added parasitic drag, the S-trim made more power.

 

i haven't seen any quick cars (fast then 11s) with a pb600. There are a few local 5oh guys going 9.90/80s :blah:

 

5.0's are lighter than most fbodz and as engineermike said "LJ is doin 9.9x...with an s-trim" in an fbod.

 

LJ and a S trim? I was pretty sure its a YS or YSi trim..... FWIW I think the P600 is a bigger head unit CFM wise. I have one of each, the P600 tensioner set up sucks, the Vortech has a nice tensioner but seems to make less power.
Just my .02 worth.

 

LJ ran 9.9x with an S before switching to the YS.

 

I didnt know that, cool.
I stand corrected.

 

I have owned a P600b and would highly recommend a Vortech S-trim over it.
