I think I would do the LT4 High pressure pump and injectors for sure no matter what.

Have you had a chance to run it at the 1/4 mile?

I love my 16 with the Maggie it can be pretty violent when you want it

The next time I decide to put it in a shop I'm sure it is going to get the LT4 mechanical pump and injectors. I took it to my local track but they removed the 1/4 mile sensors and it is 1/8 mile only. I was so disappointed I didn't post up results but the car definitely is a little slow out of the hole. Best I could muster was 1.8 60 foot, 7.7 1/8 @ 97 mph. I think it would make up a lot of ground on the back 1/8 mile but doesn't have the jump off idle like you get with a PD supercharger. I have kind of turned into a standing mile guy of late and I keep thinking if I add the LT4 parts to this car it may go over 190 in the mile.

The one under the manifold can be modified by cam lobe or lash cap but is limited by the intank pump on our cars. Just want to make sure I am tracking for our cars. Still amazing numbers and sounds like a perfect driver to me.

I'm just going to sum up what I have been told. The LT direct injection motors have 2 fuel pump systems, first is the electric in the trunk and second is a mechanical that is driven off the cam. I have been told that if you take a stock LT1 and upgrade the mechanical pump and injectors to the LT4 system it will make about 100 more horsepower without changing the electrical pump in the tank. I have also seen first hand on my car that leaving the mechanical pump stock and adding a bigger electrical pump in the tank will give about 100 horsepower. Supposedly if you change both the mechanical and electrical then you finally will get to the power limitations of the turbo/supercharger.... Give or take, I still do not think anyone has over about 1200 with an LT motor because that is all the fuel you can get in there with the current technology.

Is AGP offering a kit sometime soon?

I think AGP will have a kit available for sale within the next year. For now they are willing to hand fabricate everything if customers are interested.... Most of R&D has been done on my car so I assume it would be fairly simple if someone is interested.
