I'm about to order one from WMW (great customer service by the way).
I was wondering if anyone has one or knows if it produces any performance gains. I'll also be ordering a 15% pulley from them!

thanks for the help guys

 

l'd like to know too, maybe more whistle

 

Honestly I doubt it does much if anything at all, but i've heard of mustang guys doing it. I guess if your heads aren't ported it should negate it. Just checking though.

 

I am also curious what kind of gains porting/polishing the supercharger would show. I know endyn has some pictures of ones they have worked over but no advertised empirical gains.

 

Im still new but seems like if you havent gotten the pulley yet should definitly do that, and a 995$ mod w/ not much info seems like to big a step for me
but thats me i looked into rmw street cam and injectors with alta pulley and cai, thats the route i think im taking, but then again im still new
would love to hear more about the ported supercharger also
Good Luck with the build

 

well my supercharger broke so I ordered one from WMW. otherwise I think i'd spend the money elsewhere too!

 

ahhh i see, well then yea that makes since
GoodLuck

 

I read somewhere that people have seen 15 hp increases but i find this veryyyy hard to believe. Its strange nobody seems to know though, I even asked the guy at WMW and he said hes never seen a dyno for it..

 

If there were measurable gains rest assured that the vendor would be advertising the crap out of it.

Call the vendor and ask point blank, nothing to lose.

 

Did that, he said no one has dyno'd it individually that he knows of. the only reason im curious is because I know it does actually provide significant increases on big v8's. (not that our little engines are even close)

 

So, if the vendor/supplier does not think that it will deliver gains, as is evidenced by them not willing to take the data, then it likely will not deliver anything measurable.

 

There is power to gain. Increasing the efficiency of even the output on the supercharger would lead to at least a few hp. I don't know the full extent companies like endyn have gone to on the inside or inlet of the supercharger. IIRC I read M7 did some work on this a while back (old thread). Maybe Randy has some info.

The question is rather is it worth the effort.

 

I do believe there to be gains in the ported supercharger. But no one has dyno'd their car, then same day swapped the supercharger ONLY, then redyno to see the gains. That is the only honest way to test the gain of a ported supercharger only. So I won't lie and give people a hp number just to sell it. But when I've installed it I can say it makes a little more noise, and feels a little smoother. It's not a 15hp gain, but there is gain there. We are really selling this as a do it while your replacing the supercharger, not do this to gain power. Cause we all know the supercharger is going to die, but why not upgrade when we replace it.

 

Do the rebuilt SC's have the rotors recoated?

 

And that is why I love WMW! no BS.

 

+1...no BS I'll go this route when my supercharger fails. Thomas let us know your thoughts when you get yours installed. I would like more info. on this.

 

When the front end of my supercharger needed to be rebuilt last year, I thought I'd spend a little extra money while it was disassembled and have it ported. Based on the results, like WMW said, I wouldn't spend the money just to have it ported. I really want to believe that it gave me more power especially after spending the money to have it done, but if it did, it wasn't that noticable.

 

1st time on the internet for awhile. I have ported ENDYN SC (since mentioned earlier post). I have quite a bit other odds and ends, but I ended up with 270hp at the wheels (and not on Jan's dyno by the way). Don't have any idea how much is from that, and how much is from other things, but I'm sure it didn't hurt...
