Got my blower ported
To go along with my Ported head I am adding to my collection my now Ported supercharger. I will be using a 2.7" pulley and an LS4 throttle body. I know I'm already going to be told that I don't need the throttle body but I'd like to see how close to 300whp I can get on 91 octane. I didn't say I would get that but just curious to see how close. I am also going to be adding a ported lower intake manifold to the collection soon, along with it being converted to a single pass system.

I'm not going to because it increases IAT2's and decreases hp. At least that is what I read when we were in the stages of porting the blower. We did what Eaton said to do to spec.

Unfortunately a true story. I do have a meth kit but my controller is no good and a controller alone is like $150+ from Devils Own. Also, it's my daily driver so numbers don't mean too much to me. When I track it I will care a little more. I hope to do a low 13, high 12 on a set of MT slicks.
I would of pay your friend if he did my

I did thought about going LS4. After I did some research around this forums. Some guys like them and some don't. All I know if you set area scaler to 4950. But I have no experience with them, I was like Yeah then Naw. I just don't get really good infos about them, Most guys has a mix feelings with LS4. I did asked if it's daily driven and all I get back is Yes n No. MrB, What's your experience with them ? Is it worth it ? I have 50# on 2.8 pulley.

you can run the scaler up past 4950 to help with the touchyness

I know that the guy tuning my car said I don't need it but I do know he can tune for it because he has before. I am confident that he will make it drive nice and get some decent power.

"The two oval slots on the output plate are air leakage ports. Their only purpose is to decrease operational noise from the blower. Arnie, from Eaton Corp., explains their function like this, "When you stomp on the gas, the boost shoots up and the air flow goes supersonic. The air then slams back into the output plate and through the leakage slots, which reduces the hammering of the air into the housing causing less noise. The OEM can not have such loud NVH, that’s why we put them in the housing. The 2 small ports are not there to feed air, only to reduce noise." 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. Closing these ports will not increase IAT's; however, it will make the supercharger much louder when in boost. As an example, aftermarket supercharger companies, such as Harrop, Roush and Magnuson do not use these slots in their blowers. It should be re-stated, that you should consult professionals regarding closing these ports; and do not, for any reason, plug them with JB Weld. Improper closure could eventually lead to pieces coming apart and loose debris destroying the rotors and housing. Opening up these ports will only have a negative effect on efficiency. Do not port them."

Then you didn't read what Eaton says about the silencer holes.

Off topic but I am so disappointing that I can't find a Corsa Touring exhaust system anymore. Too bad they discontinued them 2 years ago. Your car sounds great. You should make some videos of your ZZP stage 1 cams install. I might go with that set as well but for now I am content with what I have and am doing. I'd be happy with 270 whp. Your car is by far one of my favorites on this site.

You're not gonna see any huge change either way even plugging them. Just have a louder whine.
