Is this for any hp gains or?

 

[Jokerzl]

10-20 hp and a more broadened power band

 

[Bob Kazamakis]

Looks like a lot of scoring in the housing

 

[Jokerzl]

I dont touch the casing. You loose sealing with rotors doing that.

 

[Bob Kazamakis]

What.

I'm saying the case you're porting looks fucked by the rotors that were in there.

 

[The Broken Regal]

Is that xtants gen3?

Yes it is

What.

Thats typical in super chargers. My case with 30,000 miles had similiar scores. Noted it was an eaton as well

It should not be scored that's your seal against your rotor, a scored case = less boost

 

[Bob Kazamakis]

Yea.....no. Looks like a practice case to me. I wouldn't use that junk

 

[DOC-Z]

The one I home ported didn't have nearly the amount of scoring inside as that one does. You can have the inside coated:

Supercharger Rebuild Services from Embree Machine at the The High Speed Lab, Eaton, MINI Cooper S R53, Powerdyne, Kenne Bell & Whipple Supercharger Rebuild Services & Supercharger Kits.

Does the porting look good?

Tough crowd

looks ight to me, i would sharpen the edge of the v cut

 

[SleeperLS]

bunch of these guys have too many negative opinions and nothing constructive to say...I learned not to take it personal even though it is annoying.

the edges look nice and clean and the intake part of the housing looks nice and smooth and should allow less restricted air flow. Might have to run a smaller pulley, but they exist and there are plenty of size options to optimize boost. It looks like you have great prices, so IMO good shit. I highly doubt porting that case it is going to hurt anything...it is a gen3 and could use some help. I have heard from several people that porting the gen v case is pretty worthless though.

I roll my edges give them a rounded edge. Round edges flow air better then a knifes edge.

I don't believe we've seen any appreciable issues with scoring and reduced boost so long as you continue using the rotors that came out of that case. Now if you're swapping rotor packs then yeah you might make it a bit worse but the M90 is so inefficient as it is that you're not going to notice a loss of power here unless the scoring was done by a foreign object.

 

[Yaj Yak]

Go back to complaining about LA and rental cars mike.

 

[Xtant12]

Ah yeah that is my case. And Thanks to Jokerzl for doing the work. That charger and intake have been sitting in my garage since I did the full size ic and all the other stuff from ron v's install. I dont know what this scoring issue is but never the less, Thanks again for doing the intake and charger for me. I think it looks good!!

 

[Jokerzl]

I hope you like it

 

[PANDA]

I ran a ported Gen III on my GTP, and then a ported Gen V. Both were done by reputable guys who have ported many blowers. I didn't really see a noticeable performance difference between the two.

 

[Turbocharged400sbc]

to be fair your gen3 was heavily worked and i "cleaned up" the gen 5 aside from bar removal for IC

gen5 is sooo easy since the inlet is so nice with just a little cleanup and blending.


case scoring is hit or miss dep on how deep and if the rotors grooves match up...regardless no one gives a shit cause junk
