Yep see pics below. The picture of the elbow shows where it snapped off. The picture of the blower you can see the black where hose was rubbing on side of case. The lip circled in red i'm going to chop off and still hold hope this might work. Chopping that off wont fix all the issues, as it was side to side clearance that was the problem. So, I am also going to switch to an aluminum fabricated coolant tee and route my heater hose differently to see if i can make the clearance. I bought the heater tee today and had it priority mailed and going to buy a variety of 45* and 90* coolant elbows to try.

My swap parts are all from Andy @ Adm Performace. He said he hasn't had this issue before, however I also used his HE mounts and had to chop/modify/drill them to fit as they werent even close on my Yukon. Not sure if my car was built on a Friday or what

Interesting. If you had some pictures of it when you get it re-mounted that would be awesome. I’ve been casually researching whipple and LT4 options for when the warranty runs out!

Whipple told me this morning their gen 5 will be out for us in the next 3-6 months so you might be looking at a good time!

I went and threw the SC back in. Here’s the HUGE amount of clearance you get with the heater core inlet at the firewall.

are you certain he has installed in an SUV previously ?? the truck patform offers way more room than the suv.

That sucks. On my 02 it’s tight but not that bad. It’s a different design on my Whipple but it still isn’t the best. I want to replace those T’s since I didn’t think about it before installing the blower but they’re just in a bad place now. I figure if one breaks I’ll have no choice.

I actually think the LSA on the gen 3's had more room than this. I bought a crap load of quick connect 90s an other heater hoses. going to see if i can come up with a solution that doesn't look like dog shit.

If you don't have a huge budget to support the 6K plus price tag of other mainstream blowers, it's a good option. I got my blower as a good deal from Callaway and have about half the cost of the other blowers installed. Good DD blower when you're just after more street/towing power. It's definitely not the end all be all blower, but for a DD its a good option.

That’s what I was hoping for minus the fat that it doesn’t appear to fit! ADM states it won’t fit on the 17+.... hmmmm

They fit the 2014-2018. You just cant use a 2017-2019 LT4 supercharger as the lid and intercooler bricks changed and its too tall. You need the 2015-2016 units with the shorter profile.
