I thought it was already discussed that plugging the holes in the m62 is a no no?

 

it is.

 

I agree very little

Maybe plugging it with quicksteel it is. But if it was plugged properly is there actually a downfall performance wise? I started a thread a while ago about plugging the holes and affects on performance. It was just a debate for the most part and then zoomer from ZZP chimed in and said they tested it and the car lost hp and it raised IATs. But I don't see how. I asked for actual proof but never got a response.

 

Plugging the holes is a "cosmetic" mod... It only produces more noise. I had done this to my old M62

 

eaton says you can plug them... but I also heard from zzp that it creates higher iat2's but there was no proof but also no proof to say it doesnt. Looking at euthanasias videos im probably going to get mine ported

 

eaton states the holes were put in to reduce noise. being an oem appication they need to meet strict NHV requirements. they also state that plugging them does not change the outlet temps or change the superchargers performance at all. this was all in the modding the m62 guide thats stickied here, and must of that info came from eaton themselves.

if eaton says it doesnt change the blowers performance, ill trust that over anyone else. they have spent more money than we could think building and developing the m62 supercharger. the engineers are far smarter and have far better lab equipment than anyone in the cobalt aftermarket.

 

Ya I know eaton says it's just a nosie thing. And I want to plug mine lol. But then zoomer came in saying they tested it and the car lost hp and had higher IATs. I told him to show me proof and he vanished

 

That's what Zooomer does

You can't believe everything on the internet and really, dyno-ing the same car at a different time the same day results in changes. So does the length of time on the dyno, and the settings.... Just do it

 

Lol that's what I said back to him. Just need to do something better than quicksteel

 

That's what I used. 20k miles later, and a new owner, it's still there

 

the ideal thing would be to have some aluminum plugs machined with flanges on them, and you drill and tap the blower case and screw them in using green loctite. however quick steel seems to have proven itself to work quite well. the nice thing about the design of the lsj intake is if the quicksteel was ever to fall out it cant actually get up into the motor.

 

Well I read a thread a short while ago of a guys quicksteel letting go. I'm gonna get some plugs machined if I'm going to do it.

 

if you plug your ports your a moron. even if you did get any gain it would be like +1tq or something ridiculously low, not worth even talking about.

 

Taken from the Eaton thread.

Basically, for the best flow and most efficiency, these ports can be blocked off, making the outlet port (triangle slot) the only port on the outlet plate of the housing

 

I plugged mine, 2 years ago, with quicksteel, just got a little louder *shrugs*

 

isnt there something else thats better then quicksteel?

 

weld

 

you cant weld it, tollerences between the rotors and case are too tight and welding it will cause distortion, causing the rotors to hit the case.

 

i remember someone using something similar to quicksteel but they said it was better I cant remember what it was though

 

lol welding it is better than liquid steel , he didnt ask any specifics

 

Good job ecot3c inside; Yet [b]ANOTHER[\b] example of someone talking out of their ass without researching the info themselves. The ports are there for noise reduction but a tiny bit of efficiency can be regained by blocking them off.

 

JB Weld is similar to Quicksteel. DO NOT USE IT THO. It has been known to fail frequently

 

Agree
