The intake valves on direct injection engines can get dirty over time. The reason is that oil vapors from the engine crankcase pass through the intake. Some of that oil can condense on the valves and get cooked onto them. In the direct injection engine there is no fuel washing the intake valves, so there is nothing to wash those oil deposits away. Over time the deposits build up and cause driveability issues.Haven't had a single issue with my LT1 on track. Also haven't heard of any issues with the DI system.
Aren't the port injectors on the Coyote / Voodoo only used at idle/low rpm? Thought I heard that somewhere. The primary fuel for the Coyote / Voodoo is still the DI side. And if reliability is a concern.. many more parts on a dual fuel / DOHC engine to wear or break. ¯\_(ツ)_/¯
I also like how Chevy 'cheaped out' yet at the same time Ford had to do a V3 coyote to match the HP numbers ;)
If you have the new car itch, go for the C7. Otherwise, you already have the Mustang, and looks like you have it pretty well sorted with the upgrades. Save the money for track time and tires.
The long term C7 Grand Sport trapped a higher speed @ 40k miles than after break-in in the quarter mile, doesn't appear the LT1 is as susceptible to DI issues as the older generation engines like Audi.The intake valves on direct injection engines can get dirty over time.

Yes, having dual injection means there are more potential failure points. In my opinion it's worth it to prevent the valves from getting coked up.
I wish the government would cool it a little because having emissions so stringent that DI is required is really terrible in my opinion.
I didn't realize Camaros had this same issue as the C7 Corvettes. I have never looked at a Camaro seriously enough for purchase to get to that level of detail on how they are built. My advice to you is to get an oil/air separator to minimize your future problems if you are going to keep your Camaro for quite a while
Rent a C7 Vette for a couple days and see if it's for you.As I am at the track more and more and have another car for a DD , I am wondering if I should get a C7 , or buy a new set of tires and a diff cooler for the Mustang and send it .....
What to do ?
I'd still buy an oil/air separator if I owned one. I don't trust it.The long term C7 Grand Sport trapped a higher speed @ 40k miles than after break-in in the quarter mile, doesn't appear the LT1 is as susceptible to DI issues as the older generation engines like Audi.

117k miles in the truck variant of the LT1, looks pretty good. Maybe add walnut blasting to 100k miles maintenance, and you're done.
You do know the the C7 vette and C6 Camaro both use the LT1 and LT4, right? Figured that was fairly common knowledge.The intake valves on direct injection engines can get dirty over time.

LOL. Drive a Vette or a Camaro SS or 1LE.....you'll soon realize that the Mustang is a "sporty car" but far from a sports car.Because it is.
So a Camaro is a "sports car" and a Mustang is just a "Sporty Car"?LOL. Drive a Vette or a Camaro SS or 1LE.....you'll soon realize that the Mustang is a "sporty car" but far from a sports car.
Everything you type just seams........well.............stupid!LOL. Drive a Vette or a Camaro SS or 1LE.....you'll soon realize that the Mustang is a "sporty car" but far from a sports car.
Sorry, but the GM alphabet soup engine naming doesn't stick in my head very well. No, I didn't realize the engines were the same. I probably should have, but I just didn't pay that close of attention. I only realized that the C7 'vette had direct injection only just a few months ago when I was shopping for a C7. It was one of the reasons I didn't buy one and decided to go C5 for now.You do know the the C7 vette and C6 Camaro both use the LT1 and LT4, right? Figured that was fairly common knowledge.
Could you point me to someone who has actually had an issue with this in a vette or camaro? I'm well aware of the potential issue with DI and have done my own research on the matter, but you seem to know more about how this relates to the LT1 than me.
The Voodoo is far from a bulletproof engine, yet you have no issue recommending a GT350..
