• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

how do i fill silencers

the way to go for louder whine is to get more mods. i know a 2.6 will whine like a banshee, but to get there you need a metric **** ton of engine work.
 


Why does everyone here think it will help with performance gains? It does nothing for performance AT ALL except make the blower sound more audible at idle. This is the stupidest idea ever. And you can't weld the case either...it might warp it...so goes "explore" your ideas to make it work...and we'll run a non-ported GTP vs. a GTP with the slots filled and it won't make a ****s lick of difference. Now if you care to dyno your car before and after on the same dyno, same mods minus the slits filled, AND same air temp...and you make more power...then I'll laugh...and say something was wrong with the dyno. /This Thread.

God you're entertaining. The simple fact is that they do reduce efficiency, period. Think about it, you're feeding air back into the blower, how can it not? This is an OEM blower, so a small efficiency loss is worth it to keep it quieter.

I did think about it. And I am just tired of hearing all the ridiculous claims in how it helps you out. Show me some hard evidence...not much to ask I don't think. I know you know your sh*t that is why I am saying this. Provide me something and I'll make sure not to knock the idea anymore except it is still a dangerous deal with the epoxy IMO.
 


You know, this has gone back and forth on every site for blown cars that I've come across, all with no hard numbers either way. What I have seen more than once are statement from people inside eaton that the holes are there to reduce sound by allowing some backflow. Feeding already compressed, heated air back into the rotors to be compressed and heated again can't be a good thing for efficiency, can it? It sure as hell isn't going to be a seat of the pants difference, I'm not arguing that.

Then again, we're screwing up the efficiency by putting on a smaller pulley anyway, so who knows.

Good point. So here is what i will do. I am taking ym car to the dyno this week to get a base line. After I do that, I am gonna close off my ports and run it again at my buddys shop.... If there are any gains at all, The dyno will show it. Sound good to everyone????

No...the thing to do when porting a blower is hogging out the stock "V"...not filling the holes :th_shakinghead1:

do i need a machine shop to do that or can i do it with my dremel as im pretty good at polishing with it already. how far can i go with it if i do?
 
you can do it with a dremel, but youre going to need some serious bits. there is a lot of material to remove.
