Safely Filling Silencer Holes on ported Eaton M90 Gen III Supercharger with (PICS)





it's not louder at WOT at all. it's louder during part throttle where you're boosting maybe 3-5 pounds of boost.

for the effort, and i've had them sealed on my car, i think it's a complete waste of time.
 
sorry for the delay, here is a before and after from inside the car


Before: 3.4 w/ supporting mods before Port and Polish - YouTube
After: 3.4 w/supporting mods after Port and Polish with silencer plate - YouTube

car ran good for 2 days then seems like a loss of power, realized it didnt like the tune i had from the intense 1.0 pcm, so i purchased hp tuners and been playing/learning with the tune, my maf sensor was way out of calibration from the new mods. I will say out of all the things i did to my car the hp tuners is by far the funnest. its amazing what changing some numbers in a few tables can do as for performance. i will post more vids after i get it tuned right.
 


Also had the low oil pressure idiot light in my dash on and hp tuners was reading my oil psi at -15. I just replaced the sensor 3 months ago so i figured it was still good. i have a light ticking that you can only hear at 2500 to 3500 rpm under load, figured it was a collapsed lifter that was not priming or a small exhaust leak at the cross over pipe to the rear headers. i pulled the idiot sensor out and taped a mechanical oil gauge in the port and mounted it in engine bay with new oil and filter 10w 30 syn. I was scared to start it and look at the pressure..... Cold start, idle in park it was at 60psi. THANK GOD!!!!!!!!! I still dont understand why hp tuners is reading my oil psi at -15. I purchased the mvpi standard new directly from hptuners.com for $540 shipped. does anyone on here have the standard mvpi on a 98 gtp with an oil pressure reading at -15?
 
Like Matt says there is no sender it's just a switch. You're seeing the default reading in HPT.
 


Yea 15 psi and you're done. You can just plug the hole or get a oil pressure gauge and put the sending unit in that location.
 
I just had my ports welded shut by a shop they knows what they are doing. They are the best in the Cincinnati area, so if anyone in Cincy area wants this done they only charged 50 bucks. I thought this was reasonable since it is done with a nice pretty bead...lol. As soon as my damn motor is finished, I will post up a vid. The motor is done, just not in the booick yet..
