So since I am not going to get the super duper deal going on now with the TVS, I am going diff. route. Was thinking of going to 2.8 pulley? Currentlly with my mods and a 3in pulley I am at 7psi. Do you guys think that the pump and injectors that came with the maggie will support the 2.8?

 

Meth would be a good addition. And I went with a boost a pump to make sure my fuel pump is always seeing full voltage, Lingenfelter uses them in their twin turbo corvettes often to avoid dropping the tanks to install an aftermarket fuel pump. I'm only pushing 7-8 psi right now, but good to have anyways.

 

Do you have a 6.0L with MP112 now? What injectors and fuel pump? You need to reveal a few more details before anyone can help you.

 

What I have on my sig. 112, 255 fuel pump, injectors that came with the maggie which are 42#.

 

Your injectors are bound to be on the edge as it is, I'm running 7lbs with the slightly larger injectors that come on the TVS1900 (49lb Bosch injectors as I understand) and I'm seeing 98% IDC. Maybe you can compensate with 100% meth, I've been considering it, but 60lb inj would probably be a good adition.

 

What injectors are a direct swap in 60#.

 

I agree that you are going to be pushing it with your injectors. I have 11lbs on a 2.9" pulley and am running 44lb/hr injectors. I have the stock fuel pump, but I also have a flex fuel.

 

I had basically the same combination as you for a while except for the addition of the GT2-3 cam and I was at 108 IDC, so yes it will do it without going lean but it will be past the ragged edge!

 

When I had the Radix, I ran a 2.85 pulley making a little over 9 psi on my 6.0 and the injectors didn't like it one bit. SRT10KILLR sells plug n play 60#ers.

 

I ran the 2.8 pulley on my 5.3 with the 42# injectors with no issues but if i had it to do over i would have swapped for 60# injectors.
