my sc mod

well im bored and finally got these pics on my computer so i thought id share it with you guys.

i made this mabye 2 winters ago. havent dyno tested it so i dont know what gains are to be had if any.

the purpose of the plate is to help smooth the transition of air going from the sc to the intake.

i have talked with a guy who after i showed him he said they do the same thing on their blown vettes. he said that it diddnt mahe more hp but helped change the torque curve depending on the radious they used on the plate.


machined the outlet so the plate would sit perfect.


the plate by itself(used 1/4" radious)


put them together and this is what u get.

ahh i might epoxy those when i take my charger off to get the style2 hub placed on. How long does it take to harden also. How long it take to make that metal piece looks fairly simple. also if i take the supercharger off as long as i don't unbolt the snout from the charger no oil should drip correct

also if u make more ill buy it off u = )

not sure if they r using epoxy or not so i would check up on that b4 you do it. all machine work was done on a cnc . the charger wont leak unless you take the drain plug out

i hadnt planned on selling this but if theres enough interest i might be able to make it happen

nope it just sits in there. its a pretty tight fit. bolting the sc to the mani holds it there just fine. at first i was going to use small bolts going into the side through the sc outlet but wasnt needed

I want one !!! For real..... That way i don't have to block off the silencer holes with epoxy. I assume that plate made your charger alittle louder ? I want one for sure ! Make me one ! PLEASE !!!

You missed the 'machined the outlet' part. The M62 needs modification to use the plate, as it isn't a drop in solution. Not sure how much benefit it would create on this blower. Plugging the silencer holes increases the efficiency of the blower a small amount, but I'm not sure if this mod would do any good, or potentially hurt it more.

Cool ingenuity however!

ya it made it a lil louder and it is a way safer way to block off the holes.

as far as making them. im not sure if i can make it happen.im moving soon and wont have access to an cnc . if theres a vendor interested in picking this project up they can pm me and i will work something out so we can make it happen.

thanks.
and ya hes right the plate is the easy part. making a jig to hold the supercherger in the cnc was a pain in the ass.
as far as i can tell from the ass dyno it picks up alot faster down low, cant tell a difference up top

Thats a great idea for plugging the holes! I want to plug mine but so far theres no safe way to do so. Until this. I would be curious as for actual HP gains if any. I would definatly be interested in one. How much did it cost you to make?

this should help out drastically, it's going to straighten the air right before the intake manifold disrupts it again!

lol

no im a cryogenic pipefitter actually. a friend of mines dad did the machining i just sat there w him and told him what i wanted. he charged me 300$ i kno thats alot. but he had to write the program,make the jig for the sc and whatnot.

i dont think theres any hp to be made with this. if anything it will help the torque curve

Very nice, I would suggest machining one that fits in the plugs and fits the stock m62 without machining.....even use phenolics or something as an added benefit....sell them things! i would buy one!

making one that fits without having to machine the outlet would be hard . theres a sequence of #and letters on the outlet that need to be taken off so it sits flat and air cant escape around it

But theres still the chance of it coming apart and going through you're charger and intake. Not worth the chance for the gains you get.

well the peices wouldnt go through the charger because they plug them after the rotors, and the laminovas would stop the peices from going into the head so i wouldnt worry tooo much about hurting anything besides a laminova mabye. having said that i would never plug them if i diddnt have this plate.

Some are scared to use it. I wouldn't worry about it if you do it right and let it sit. It literally sounds like steel when u tap it with ur fingernails. There's no benefits from this just louder wine
