So what is the consensus of FI on top of 12:1 DI?

The 12:1 is not a problem. They have supercharged and turbo gt350's that run 12:1 compression ratio.So what is the consensus of FI on top of 12:1 DI?
TRUE THAT.once the tuners figure it out.
This is pure speculation but I don't think it's going to take an intake manifold. I bet this one already has one on it that flows just fine for the 7500rpm that this thing will turn from the factory. I'm thinking a CAI and tune to hit 500 to 520 at the crank.NA route for me!
CAI, Intake manifold, headers and a good custom tune should see this around 570-590HP crank with 12:1 and the DI/PI on the engine. Mated to the 10-speed thats gonna be one damn quick Pony, well into 10s NA easy on slicks and maybe even street tyres.
Cool part is Lund Racing has so much data with the Ecoboost DI engines and the PI Coyotes already. He tunes my DI Ecoboost which has auxillery port injection tuning on top of the DI, and he has made it work great, he hates how antiquated the aftermarket split second system is, but he has it mastered. I bet they are excited for something new to play with. I wish the Ecoboost would have PI and DI like the 18' Coyote will, id be excited.once the tuners figure it out.
Thanks, good to know. Haven't paid much attention to the S550'sThe 12:1 is not a problem. They have supercharged and turbo gt350's that run 12:1 compression ratio.
The DI should help. I believe it helps cool things down, has more controlled fueling, and should help prevent running lean. I could be wrong though.
I think this thing is going to put down crazy FI numbers.
Any other engines besides the truck 2.7/3.5's have the dual injectors yet?Cool part is Lund Racing has so much data with the Ecoboost DI engines and the PI Coyotes already.

This will be the key.Wonder what the hpfp will handle. Will it be the usual weak spot or will it be stout.
Its a ford, it will break. Honestly Im not a fan of direct injection from a performance stand point when it comes to modifying cars. But tuning BRZs are easy enough. Should be similar.This will be the key.
Neither am I. A lot will depend on how much headroom exists in the stock HPFP and how reliable it is. I have had two DI vehicles so far, both modded. The Focus ST was extremely limited by the HPFP and the Subaru I currently have appears to be OK on fuel requirements as long as you stay with pump. Throw in the issue that E85 typically cuts the lifespan of the HPFP significantly and it can throw a wrench in the equation. The added port injection should surely help with fueling requirements, but there will definitely be a learning curve.Its a ford, it will break.
