FBO 5.0

2015 Mustang GTPP (3.73)
Lund 93 Tune
PMAS CAI
GT350 IM (Stock TB w/ adapter)
Corsa 1 7/8" Catless Longtubes
Corsa Extreme Catback
Polyurethane Motor Mounts

Anyone have similar mods who can share or speculate on what I'm making to the wheels?
I won't have time to schedule a dyno run for a while and I'm just curious.

Also, while I'm N/A is there a large benefit to add in some 47lb injectors to support an E85 tune?

Thanks in advance. :cheers:

Should have got a Lund ff tune, 47 pound injectors if you really want to take advantage of that manifold and using E85 with high RPMs the stock ones are near static. Upgraded fuel injectors and just being FBO you're going to get much better throttle response can it seems to pull a little harder up top. On 93 octane with your mods you should be around the 440 450 range with E85 you could add another 10 maybe 15 hp

Thanks for the prompt and polite reply Kahboom. I'm still within my initial testing I'm sure I can ask Dakota with Lund to send me over a FF tune to do some testing on. I'm in South Florida where this is E85 but its not on every corner.

I'll go ahead with the 47's because they're pretty inexpensive anyways. My only question is when you say the stock ones are static, I don't understand what you mean.

I believe it's about 7,000 RPM or close to it that the stock injectors are near maxed out that's 100% duty cycle on E85 versus the 47 s which is something like 80 or less duty cycle. Plus the 47 the throttle response is much better and it seems to pull harder up tough to even on regular fuel

Okay I understand now. Thanks man.

47# injectors are nice to have in a sense that they have a 6 hole design vs. the stock 4 hole design. Better overall atomization, especially for the additional flow rate of e85 that is required.

Agreed with the 440-450 range.

My car put down 430 without the GT350 IM.

Seeing as you're a manual I agree with the 440-450 predictions, probably closer to the 440 end of that range. Seen a few builds that are just like yours but they were running a Lund FF tune with E85 and they were around the 460 mark.

We have similar set ups. Your estimation for HP numbers would be based on a Dyno Jet. One thing I learned going FBO is that my suspension needs to be close to FBO as well, or your spinning tires with 3.73 gears. You gotta be okay with going close to 7300-7500 RPMs to get the full power of that IM.

Agreed 440whp ish with this setup. My sig shows what my 2015 made on similar.
