Whats the approximate power limit of the M122 supercharger? Could it get a Gen III LS to 800HP-1000HP. Provided that the camshaft, exhaust, intake, and tuning is correct? I realize that it would be hard for a 4.8LS to reach 1000HP or even 800HP (if even possible). As much as I like immediate response of Roots style superchargers the boost can't simply be turned up like with turbochargers. Thanks for any thoughts.

No way it will make even 800. Maybe 650 is the limit.

I thought my m90 swap was a pain in the ass, yours was worse. I bought an adapter plate to mount the m90 to a Holley lo ram manifold. I cut my m90 with a sawsall and it took more than an hour. I ported the m90 and had 1 90 degree 4 inch tube tig welded to it and had to have another 45 degree 4 inch tube welded with v band clamps so I could attach the throttle body. I had the silencer ports welded shut by the same guy that welded the 4 inch tube on the blower. I had to buy a custom 2.55 inch supercharger pulley from Nathan Herbst of smoothflow pulleys which had the ribs going to the edge because of a belt misalignment. I have a 7.4 inch ATI balancer and I think I'm spinning the blower at like 20,800 rpms. the hottest I've seen it get is 161 F. this is on my 6.0 LQ4.

How much boost do you manage? Even my m122 is too small for my 6.0, id think an m90 is almost nothing for boost?
@lifeishard121127 күн бұрын
@@hackjobhotrodshop5075 I've seen it make about 4.5lbs. I live in Wyoming and the elevation is 7k feet so I've wanted to add boost for a while.

@limabravo6065Ай бұрын
A lot of people dont know that back in the day Ls engines werent cheap and everywhere, because all the junkyard units you can grab for a few hundred bucks were still on the road lol. And i did this similar style build in 2006 when i drove my 98 v6 camaro with no oil in it. It was winter, i slid off the road and a branch went all stab happy on my oil pan😮 So i went to the local yard with a shopping list and i got the L67 heads, intake, m90 mighty weez, and shoved all the sensors / injectors into my pockets because the brole struggle was real back then. So my short block was being rebuilt while i tried to figure out what the hell i was going to do for an intake elbow as i didnt want to cut a hole in my fire wall and have the air filter where my radio was. Then i remembered that Australia exists and their Holden rwd cars used the l67 with an intake elbow perfect for my purposes. Now this was asi said back in the day but ebay was a thing and the internet in general allowed commerce between continents so youd have thought finding a used intake elbow from down under would be relatively easy buuuuuttttt noooooo. It took months to find one and then work out how to get it from the land of all things dangerous and or poisonous and when it finally showed up it was cracked and just a PIA. So i took it to a local welder who was able to zap it and make it not be a giant leak. And just as that was done my short block was also done. So with refreshed heads, a smaller pulley, and an OG megasquirt i set to making my 3.8 dreams come true 😂. All said and done it made 302 hp at its 16in tires, after having demanded its tribute of about 5 months of my life and way more money than most 5 or 600 hp junkyard ls builds do today. Torque was good to at 338lb ft and the T5 transmission never even blinked outside of me smoking the original at the time 98k mile clutch before the swap. Its been so long that im pulling the motor just to freshen her up and seeing what i can do with the supercharger as the eaton huff and puff is about maxed out and ive since started building speeduino ecu's which beat megasquirt out in every measure i care about including how powerful the hardware is. So yeah cool build sorry for the novel butni broke my leg and im a little vored lol

I have just come across you video about the issue I am dealing with now. So I connected Pin No 17 on red connector to my vintage air compressor on my LS swap. I made the changes as well in the hptuners as indicated in this video. So I turned on the AC, the status of “ AC Requested” became Yes but the “Active AC” was showing”NO”, and the idle rpm did not bump up at all. Any idea why the idle rpm remained the same and why the AC mode did not get activated. Thanks.

Are your idle trims in gear or park within the range I said? Is the computer getting 12v from the AC clutches?
@72Z28Ай бұрын
Thanks for the reply. The trims are within limit I believe. LTIT is showing or around -2.7g/s, which is not bad I think. However, I need to make more adjustments once I get done with VE&MAF tuning. Yes I connected pin 17 on red connector to the AC conpressor wire that’s activating the clutch and I am getting “AC requested” signal and indication as “Yes” But AC is still showing inactive.

I was not aware that the fuel tank needs to be changed to an EFI one (apparently the shop wasn’t either). I am confident this will fix my issues.
