Forced Induction motors that have died

Dont the MAF sensors handle the temp readings or with the stillen kit those go away? My tuner had the temp on each bank and my upgraded MAP sensor readings?

Where are your MAF located though?. Adding the SpecZ 3bar MAP sensor at the manifold gives much more accurate readings.

I'm making a custom charge pipe so I can move the MAF right before each TB, and they won't be measuring the same air then either. I'm also ditching the coolant lines to the TB's, no use heat soaking them more than they already are.

I too started out with the Aeromotive 340 running a e70 blend and at 12psi the pump just could not provide enough fuel giving the z AFR cut while in boost. Had her upgraded to a Walbro 450 and she now runs Nice & Rich under wide open throttle at 12psi. I can now even run a higher blend of "e" since upgrading to the larger fuel pump.

With you running 14psi you definitely need to find a way to add more fuel to you're new build. You should hit up Charles from CJ Motorsports as he is working on a twin Walbro 450 pump setup.

Those twin Walbros are going to move some serious amount of fuel!

Seb has been recommending the Walbro 485 for me even though I won't be running e85. Just doing my install right now, but have the si upgrade from Vortech and also 9psi pulley - I'm going to start with the stock 8 pulley first and see where I end up. Hopefully the frozen boost IC, BOV and MAF/MAP changes will let me get into the higher boost numbers that the setup is capable of, but want to ease into it and make sure no boo boos along the way lol

I can't imagine I will need more pump than that, but good to know Charles is doing a twins setup if need be.

EDIT: What regulator are you using?

Did you upgrade the stock fuel pump wiring to accommodate the added voltage draw with the aem 340l pump. Just curious because this was the pump I was going to go with when i switch over to e85.

It's recommended to do the fuel pump relay above 500whp regardless of fuel pump used.

What is the fuel pump relay?

Is that something like the CJM S1.SE fuel system?

Do your research. Every question you've asked is covered on this forum already. Use the search function.

A fuel pump relay kit is a modification to upgrade the wiring to the fuel pump. Larger fuel pumps pull more current and the factory fuel pump wiring circuit will become a "restriction".

The relay/wiring upgrade is a standalone modification from the rest of the fuel system. Although the CJM Billet Top Hat really finishes off the relay/wiring upgrade because it uses larger terminals through the fuel tank flange. Using the stock top hat means that your wiring upgrade still has to bottle neck down to fit through the stock fuel pump wiring connector.
