Christmas tree port ftw!!!

GLWS man

 

Thanks
Thought I would add this as well. This test was done with the car still strapped down, swapped blowers on the rollers.
The low graph is my original blower with a 2.6
Inlet opened for ls4 but not polished.
High graph is a blower with this outlet port only, spacer used for ls4 (less than ideal). Same 2.6 pulley.


----And side note, these graphs are in std. My 309 graph in the dyno thread was a 2.5, ported outlet, done the same day, but I accidentally uploaded the sae graph before seeing most people use std. Std on the 2.5 was 317

 

Really hogged that thing out! wow

 

Good stuff!

 

i was just about to ask about gains .... that dyno sheet says it all lol

wow good work.

 

I am very interested.

 

hey armcclure,

if blackie beats me to this, would you be willing to do the same port job if i sent you another case ?

 

Absolutely. Pm me.


IAT2 dropped about 10* also but I can't find the logs.. May be on my old computer somewhere.

 

How hard is it to swap this on?
Ive never taken apart a supercharger.

 

i was going to ask this same question but didnt wana look like a dip **** lmao

thanks for takin the bullet for me

 

No problem lol.
I would rather ask some one who I know is knowledgable

 

Not hard at all. Only a few bolts and it comes apart in 3 pieces. Housing, rotor pack, snout.

While ur at it, pick up a zzp coupler and a bottle of gm blower oil.

 

Yep. Once it's off the car it takes 10 min. If you're careful you can even do it without draining the oil. But if you haven't done it recently I would recommend a coupler and oil to go along with it.

 

I was always under the assumption that a port job should never touch the outlet. This is interesting.

 

Normally yes, but this port job actually has it's benefits.

 

That has been battled back and forth for years. For a blower operating within the oe compressor map, yes there is little to no gain and possible damage.
Very few people here are still on the map.
This general design has been tested many times by several different people/companies to provide a gain when done properly.
This is not a dremel job. I matched the widest split close to the leading rotor closing point, done by hand. Then put in a cmm to digitize, and corrected the edges to match the rotor twist like stock. Then used a cnc to make a jig so that each one is done perfectly.

Even eaton admitted there are possible gains by porting.
We are forcing these blowers into territory they were never designed for with our small pullies, and this helps bring the effeciency back up. This case is NOT for someone running a stock/stg2 pulley.

 

Good info Alan. Would have tried this out if I kept the m62.

 

It's gone already? You def would have beat my numbers with it.

 

sub'd

 

inbox emptied

 

Oh I was set on doing everything I could to try and beat you originally, but then the TVS fell into my lap and I said **** it I'm fine being #2.

 

What size pulley would be recommended for benefits then?

 

I dont think a pulley size is the only thing too shoot for.

A larger pulley car with a ported cylinder head and cams would benefit from this port.

 

Thats why I am asking.
