I have the tc76, Very close specs to your magnum. I made 793rwhp, but it fell down by 5krpm. This turbo works awesome on a 5.3, but you need a 75mm+ turbine for a 6.0 or larger to make good power and rev out. I've been harassing Kyle for that tnetics 76/76 or the magnum 80 with the bigger turbine, but they haven't released them yet!

 

Dang thats great power. I'm pretty sure that even though the wheel sizes are the same sizes the tc 76 will flow a lot more from better design over the magnum. Is this correct.?

 

Eh, I'm not very familiar with the magnums or master powers, but a standard turbonetics t76 or t78 with a 1.15 housing would be a little better than mine, but still has the 68mm wheel. I really think the 7675 or tnetics 76/76 would be a ripper on a 6.0 with 12+psi!

 

haha i was just jk anyways i do wanna sell the damn thing though so i dont have two turbo's i'd like to sell it and get a lsxrt intake.

 

Soooooooo. Got a new billet wheel pt7675 coming my way!

 

can I try it first? Just to make sure it works correctly.

 

Only if you promise to share some of the speed voo-doo from your truck with me lol

 

Haha, that voo-doo just broke a u-joint last weekend!

Well at least take some pictures. I'd like to see the compressor cover off and a look at that billet wheel.

 

Will do

 

I have a 76/75 now and it feels good all the way to 6k. The 76/68 I had before really fell off around 5,500. I haven't turned it up yet but it feels stronger at 12-13psi.
