Nope and I could care less what a car mag shootout says frankly. That's only good for the mass sheep who read them in some vacuum and also think a sporty Camry is a sports car and "grounded to the ground."So your basically saying, if Car and driver or any other mag did a shootout between the GTPP and 1SS, the the GTPP would win.
If it's motortrend, be ready to see some ridiculous numbers for Chevy.So your basically saying, if Car and driver or any other mag did a shootout between the GTPP and 1SS, the the GTPP would win.
Youve clearly never paid for a valve cleaning. It ranges from 700-1200 every 20k. in 20k an rs4 reported a loss of 40whp from build up. Its flawwed and makes the fuel system upgrades drastically more expensive. Everyone that buys di until its perfected is a guinea pig.If it's motortrend, be ready to see some ridiculous numbers for Chevy.
But no it will not. The camaro will have a slight advantage on the GT PP stock for stock.
Which isn't so impressive considering EVERYTHING they have changed on it.
Also to those against DI... Are you just worried about build up in the valves or what else is so bad about it?
This. Carbon build up is a major major issue and very expensive to deal with. It happens on every DI car. I work on VW/Audis on a pretty regular basis and the 2.0Ts always have carbon buildup. There are ways to prevent it somewhat with seafoam treatments and such but you will still end up with some carbon build up. Also it makes upgrading your fuel system problematic. Forget about running E85 for big power with DI.Youve clearly never paid for a valve cleaning. It ranges from 700-1200 every 20k. in 20k an rs4 reported a loss of 40whp from build up.

yea I totally agree. I think the solution would be to have both port and direct injection. This way you can have the port injection keep the valves clean by injection fuel into the intake stream and have the benefit of not having issues when you want to upgrade your fuel system.The little better mpg you get from di is completely spent on the valve cleaning, and then some. It actually will cost you a lot more in the long run. I wouldnt buy anything with di.
The intervals is totally dependent on the owner. It may not be necessary but you will probably start to lose power after that point from carbon build up but your car will probably drive fine. You most likely here more about VAG cars having issues simply because they have been doing DI longer than most and have more high mileage cars out there that are DI compared to other brands. the 2.0t is used in like every VAG car now in some fashion and has been for a while now I think since like 2005.20k intervals? Wtf? I know plenty of engines with DI but it's always the VAG stories that concern me. My E92's N54 needed one walnut blasting.
Already being done (in the Subaru BRZ and Scion FR-S). Sooner or later others will catch on.yea I totally agree. I think the solution would be to have both port and direct injection.

Well in a master tech at a bmw dealer and we do them very often. My personal dealership pushes it about every 25k. I can say though the harder the bmw is driven the less build up there is. My dealer charges 1200 for the walnut blasting process. I do a couple a week on my own.20k intervals? Wtf? I know plenty of engines with DI but it's always the VAG stories that concern me.

I highly doubt most people have enough miles on those vettes, or haven't noticed. Some people dont even notice the drop. I notice it on customers cars that didnt even complain about the lack of ooomph or hesitation.Have not heard any LT1 issues. Have there been any?
