Absolutely.

I guess you haven't had a poor experience with a relatively big purchase yet. One thing that is huge for me is service after point of sale... mainly, if something isn't right, how good is a said business at resolving an issue.

1) Would I agree that from everything I have read, the Maggie 2650 is the best blower at the moment - yes.
2) Is the pricing fair - I would say yes.
3) However if they can't even take the time to answer a few, very very basic questions prior to purchase.... it makes me believe that if I was one of the few people that had an issue down the road, it would be like pulling teeth working through a resolution.

I've blown too much money in mods over the years(other platforms), including having some sour experiences... which is all too common in the performance shop world.

Read through the thread. You seeem to be a fine example of a customer that might get "fired".

I would suggest you take your questions to the tuner, not the vendor.

Magnuson doesn't seen to want to discuss anything other than their base kits. For example, I called them to ask what belt part number I needed for a particular pulley size when a serpentine belt failed and took out my blower belt. They told me they didn't know, which is difficult to believe. I ended up getting the info from Greg (Laynlo).

As stated though, any of the top shops or tuners would be able to answer these questions for you. You don't have to get the answer direct from Magnuson. Lots of manufacturers are pretty poor at customer service when it comes to answering questions but it doesn't mean their products are bad or that you won't get support when needed. Many shops are authorized sellers for Magnuson so they will take care of you if you have questions or issues.

I think Jason is really close on the estimates he listed. You won't be unhappy with the 2650r as its a stellar blower and holds the quickest and highest mph 1/4 and 1/8 mile at the drag strip. Each may very some depending on the altitude and if your going to run 91 or 93 octane. All Magnuson's tunes are done at sea level and 91 octane. Typically you'll see more hp out of a custom tune as that tune is meant for the masses and is generally a little on the rich side. Buy it with the fit kit also and you get all the connecting hoses, reservoir, etc. Let me know if you need anything else.

After 6 months, I finally get my Maggie for my 2018 Camaro SS.
My question is, How do you pick the right combination of upper and lower pulley's? Mine shipped with a 70mm and 80 mm for the upper pulley. I have the stock LT4 lower.
I've been told to use an ATI Damper w/9.06 DSX or the 9.45 DSX pulley for the lower. This is my build in a nutshell. What do you think?

Impressive build, but I think you should be using 2" Long tubes with that kind of setup

[KingLT1]

The headers are the least of his worries. His issue is fuel system. If he is stock compression then it's not going to like the kind of boost it will make with a 9" lower(15%) and 80mm upper on pump gas. And LT4 fueling won't be enough to run much Ethanol at all. It might squeak by with a 90mm upper on E40.

[JasonGofast]

My setup on the LT4 is similar. I run a 90mm and 9.06 lower.

Stock LT4 fuel components with cam + low side will see you running out of fuel quickly if you try something tighter. I have meth in my setup and that's just for running 93. You probably won't be able to run e85 unless you get stronger aftermarket fuel pump and injectors.

Get a 90mm pulley and start there first. A 70mm is going to make 18-19psi you’ll be out of fuel, and that’s too much boost for decent power on pump. You’ll be dropping timing quite a bit to compensate. Shoot for 14-15psi.

I can run 40% E on my build with my Holley low side. (400 lph)

[EDFHOBBIES]

I think you try your stock lower of almost 8 inches and your3.15(70mm)

I'm at 8.3 lower and 3 inch upper making 1000 on all E it was 930 on 93.

We have roughly the same build I don't know your compression and if your cam is efficient as mine. But the ported Heads, 112mm tb, and everything else is identical. If maggi is half as good as it claims you should be right there with me.

Agreed. These cars are literally all about fueling…the rest is cake. A serious build needs a built low side fuel system like Fore Innovations and either:
1. Port Injection
2. LPE BB HPFP w/+52% injectors
3. XDI pump w/+60% injectors

[Jwynn]

Wow, so many options. Thank you all for the help. I only thought that I did my homework before I opened this cans of worms. Lol!
I want to stay on 93 pump gas. If needed I can do without the E85. Like anyone else I want as much HP as I can afford. I'm pretty much at my limit. I still want it street friendly.
I won't have unlimited access to tuning and dyno. Sounds like I should start with 80 to 90mm upper and 9" lower.

LOL @ 930 on 93.

If you’re staying 93, you definitely need to drop the compression at least one full point on an LT1 like King suggested. Otherwise you’ll be so octane limited it won’t be funny. Can expect low to mid 800’s on 93 if you drop the compression as mentioned.
