Its also because Direct inject only is not enough with WOT demands. LT4 engines have fueling issues at a certain power level so they added port to assist with heavy demands. It will also be a benefit of preventing coking of the valves but the main issue is not leaning out.
flat-plane cranks are mostly shit they sacrifice balance and longevity for a minor increase in exhaust flow Ford's 5.2L voodoo isn't even a real 180 crank BTW ferrari was talking mad shit on Ford for the HUGE counterweights on the gt350.
Flat planes are not better at making power. They just make power differently. It's actually more conventional than the crossplane since a flatplane is basically two 4 cylinders mounted together. An engine like this has no need for a flatplane crank it would actually make it slower because they would be forced into lower displacement and DOHC to help the engine breathe like a high revver and the supercharger wouldn't fit. It would be a mess and would disrupt the entire rest of the Corvette's design.
The air flow path you describe is wrong. The air comes out of the blower at the rear not that circular piece you pointed to. That is the blowoff valve. When the motor is not in boost that is open and puts the air back in the intake path so the air doesn't compact in the blower plenum. When under throttle that butterfly is closed so it can build boost.
CarGuy11 huh, that’s a screwed up way of looking at it, 99% of car enthusiasts are gonna assume you mean “faster”. The C7 Z06 is faster than the pussycat.
Dude, the port injection is not there to get more fuel into the motor......its there to stop intake valve carbon buildup caused by the PVC system. The LT1 motor is a huge fail with carbon build up. I have a catch can and at 15k miles the valves look like crap. with any luck the later lt1's will have the port injectors.
Original c4 lt5 was better imo.
I’d like to review one sometime.
I like that they are using port injection, will help in keeping the intake valves clean.
For sure!
why they use lt5, they had lt5 in 1990. confusing.
Yep they love to reuse names lol.
Glorious! :D Can't wait to see one of these, a true work of art!
Sure is a beast!
port injection is just to keep the valves clean
They say it needs it for fueling.

Fantastic power plant
Curious if they will put it in anything else.
Heh, an LT5 yet it doesn't have 32 valves. Way to go GM.
The LT5 has 32 valves
LT5 16 VALVES
The old LT5 version has 32. This engine has 16 fuel injectors and direct port fuel injjection..Eat that.
@@traviswerner4151 dumbass
Very nice, but I dont want that engine, it has parts missing 😎
Haha true true. Thanks for watching!
Is that a flat-plane or cross-plane
Cross-plane crank.
minor setback for almighty engine hmmmm....
(minor setback for my personal liking)

@@jjsmithlago1234 damn bro did you see the 2022 Z06 engine yet. Flat plane 5.5 and all the things you said it wouldn’t be lmao. Hindsight right

Hmm interesting.
425j1 That's the throttle body, the car pulls air in from the front not the rear.
MOST H8D Yes obviously the air comes in the front into the throttle body first. Were talking about after the air is compressed in the supercharger.
425j1 I stand corrected.
You need to change your comment in the display pic...a stock Z06 beats a stock hellcat all day...every day. The new ZR1 is faster than the Z06.
I meant beat the 707hp of the Hellcat.

It does help with this also yes but think its for emissions and power as well.
i heard late model racecraft in houston offers port injection kits for lt small block motors
i really doubt that. it turns on only at higher rpms and almost full throtle
Ya Toyota also does this for the same reason. In the FRS they were boasting about the performance improvements.
Port injection only activated when the ECM calls for PE mode. The DI can't support enough fuel for WOT.
