Yeah, sorry, I assume everyone’s in my head when I explained things sometimes. On the Buick motor it’s slightly bigger, but with my overdriven balancer, it was something like around 8% bigger than the standard balancer pulley that comes on the GT500. I mean that with the smaller pulleys it’s...

It’s just the standard size that comes with the M122, but with the smaller crank pulley, idle and tensioner length, it’s spinning the blower faster. To what degree, who knows, I CBF doing the maths tbh, but it’s on par with what we could max the little M90 to, so I’m happy. I will go smaller...

****, yeah iPhone won’t upload. I’ll have to do it tomorrow night for you guys. I’ll put both before and after videos, very different notes

Also, here’s a video of how hard the M90 was working. You can really hear how much the 52mm (2.04inch) pulley was spinning the rotors

Thanks, mate. I looked at options for throttle bodies, but the postage to Aus was more than the item themselves half the time lol. I just modified the stock one.

Thanks for the help fellas

Update for those interested. So, charger is on and working like a charm. Found a guy here in Aus that imports M122’s. He makes an adaptor kit for the LS1s and sourced a stock electronic throttle. Had to make the throttle body cable driven, that was the only real hard part. Used the standard...

well, the only thing i can possibly help with is that the whipple wont have thread in its location spots, you wont snap the bolts in the whipple, just the LIM lol. Also, with the bolts fitting the whipple, the thread shouldn't change unless the LIM is a different piece, as its only the LIM where...

Yes, i understand about home porting lol. Damn, i love seeing DIY work, giving things a go. On my little M90 at the moment, its had so much porting that a lot of the charger had been metal filled. Ive taken it beyond its casting in a few spots to increase volume. These aftermarket u-bends/elbows...

This was a mates around 10 years ago, with a whipple. the bonnet (hood) was only cut into to fit the bird catcher.

Yeah, it'll fit and ive the snout to suit. This has been done a few times with other chargers like an M112, TVS, a few whipples too; however, this setup is a little different from theirs, so we'll see what things we come across and we'll tackle them as we go.

Thanks dude. Yeah, mostly built the engine and have done most of the fabrication/install myself. Theres a few things like welding and tuning that a mate of mine has done for me, but theres been a bit of a collective effort from a few people to put forward the concepts that made it what it is...

So the charged air gets pushed out the front of the plate, into the big water to air intercooler and then pushed back up to the back of the engine bay and into the lower intake manifold. Adding an interchiller would be great, but intake temps at wide open throttle, with this huge intercooler...

legend! Thanks mate. Ill get onto reading and looking into the two companies that you've listed. Changing up form the M90 will just require making up an adaptor plate to go between the charger and the A2A splitter that sits under the blower. Ill also need to make up an external bypass, as there...

G'day, you good c#$%s! Ive a little bit of a semi unique situation going on in the land from down under at the moment. I've got myself an L67 (supercharged 3800) in my Calais (Commodore/4 door GTO) and Ive really stretched the little M90 to its limits. If i was to maybe interchill the massive...
