5.9 magnum with M122 blower/intercooler
Thank you for your response. Looks like the correct M90 generation is 5, 04-07 Grand Prix. I accidentally ordered Gen 3, but luckily was able to cancel it at the last moment :D
Did you tig weld the 2 wrong holes? I am thinking of just filling them with JB Weld temporarily so I don't invest 1500+ into TIG for now.
I wonder if it is ok add an inch or two of spacer to fit with the pulley I'm getting... Will show a picture once it arrives!
Let's see if I somehow manage to pull a similar build off with no access to machines, going to be an interesting challenge!
04-07 sounds about right.
Haven't tig welded the snout yet, I have thought about JB weld too but haven't looked at it closely. If it has to be tig welded I'll get someone who can tig a lot better than me so it can look pretty and not leak oil everywhere..
As for adding a spacer, I know Cobra Engineering make a press fit extension about that length. I've read from people who have had success with them on their 03-04 cobras.
But for me, knowing how much load goes through a blower pulley I don't consider it great engineering" to move the pulley further away from where the shaft is supported on the front snout bearing.
I don't want to be negative, but make sure you weight up the risk/reward.
It's my opinion that *If* one of those spacers experiences a rapid unscheduled disassembly at 15-18,000rpm with 50-80hp going through it, the consequences are going to be highly destructive to your hood/radiator/fan etc and may end up costing you a lot more than just getting a longer snout would have.
On the other hand, it may never cause a problem at all.
Would love to see a thread on your build, I could always use some inspiration.
Anything with a supercharger is always cool in my book :thumbsup:
