Curious about the harrop, he did t offer that as an option when I talked to him. Is it the same price as the Maggie, or is there other benefits over the Maggie? Haven’t heard much about them on a lt4 yet.

Joe liked the 2650, Erik liked the Harrop which is what I was going to do. Im not sure if there are any benefits going one or the other, I was open to either. I am curios to hear from anyone with the Harrop.

Not that I know much other than the LT4 Chevy blowers. But, Maggie seems to be popular and in wide use on a lot of the ZL1 LT4 builds! So, maybe it's a decision to be made based on popularity knowing that most that have a 2650 has had zero issues? I personally love the whine of my Kong X-Port'ed LT4 blower. I have a friend that has a Stage 5 package build with a NW112mm and a 2650 etc... on his ZL1 1LE and he dies for the sound that my blower makes! He's also shocked that I hang with him on the 60 to 130 rolls we do. I may have even inched by him a few times!!!. I paid about 1/2 the cost for my build to date as he did for his build!

Since I used the secondary cats as my only cats after my LTHers (I want the stock Cat look for the inspectors here in Thailand), you all are making me want to pull them and see what they look like inside. Since I welded in flanges, it won't take long. But it sure would be interesting to know. I monitor the temps of them with the i-Dash. It's still a slight bitch to tighten them in correctly because of the 3 holed flanges. But when I get back from the states in April, I'm gonna do it and inspect and clean them. I guess it will also give me a chance to port the flanges if there's a slight misalignment.

Maggies can whine like crazy if you spin them faster. Also, very much recommend the Too High PSI lid for it!!! They run slower than the stock blower. The big reason i went maggie was the cooling is probably the best out there, and they are still rwtq monsters like the factory blower. I have the 4.5" cats on my car, I'll be interested to see if they last also as i am jumping up to somewhere in the 1200rwhp+ range.

They do for sure! But, you wanna hear some serious whine!!! X-Port a stock 1740 LT4 blower, add a 9.45" lower and a 2.3" upper! The whine will literally be the only thing you can when at WOT !!!!

That's because it's screaming from the heat
