Installing the injection pump went without issue and went in a bit faster than it took for me to remove it. I still had the motor staked at TDC, which means that the IP needs to be at TDC for static timing to be accurate. The woodruff key makes it easy, but we can verify that the IP is at TDC by the has mark cast into the body of the IP. 360 degrees of rotation at the IP is one full revolution of the motor, so if the woodruff key is lined up at the has mark, then you know that the pump is at TDC:

Surprisingly enough, this is all that needs to be removed to pull off the IP. I pulled off the accessory drive to make it easier, but I don't think it's necessary:

IP installed, timing verified:

Some engine bay reference shots for David and others. She's pretty far back in there:

What the hay?? Are you just teasing us? Trying to build the suspense? Get that mother started!

Awesome. That video had a strange Frankenstein's monster look to it.

It did, didn't it? I've watched that video a bunch of times already

Congrats! It's a great feeling when a project comes to life. That turbo sure sounds like it spools easily. Will be fun to see how it reacts to a load.

Thanks Mike! You've been a huge help in getting this figured out.

Question for you. It seemed like there was a big delay in throttle response, but I'm not sure if that's expected. How is the throttle response with your motor?

I could certainly hear the rough idle from the injector that tested bad. New injectors are coming up soon.

My buddy Jerry took a video while starting it last night. I can't get enough!!

Throttle response should be immediate. How do you have your fuel pin adjusted? Mild or deep?

I knew the air in the Carolina's was darker than usual, it's just Johnny revving that sweet rig of his!!! LOL Way to go wonderful to hear it running on the video. Congrats and now take a deep breath.......

I can't answer that question because I'm not sure how it is adjusted. I presume that this is an effect of that white washer I found removed from the aneroid. I have not adjusted the star wheel at all and the full power screw was set by the IP shop.

Holy hell I want one.

Nice Johnny! I smiled the whole way through that video. It's amazing how different it sounds from mine. Now get out and drive it and you will grin from here 'till...Well, forever.

Yes sir, skies are gonna be a tad darker now

Holy hell I want one.

Sell that purdy 2f and get one!!

It does sound quite a bit different. I wonder if the injection pump makes that much difference or if its the turbo. What turbo are you running?

Mine is also immediate. Wonder if it's that governor spring? It doesn't make since that it would be that though because that spring is stiffer to allow more rpm before defueling so it would seem like it could potentially help response.

That washer (assuming it's what I think it is) would only limit the end travel of the fuel pin and not the beginning. I'd be curious about your smoke screw on top of the AFC housing. I wonder if it's backed out all the way which means the fuel rod will start on the shallowest part of the fuel pin. Wonder if you could screw the smoke screw down (clockwise) in increments to see if response improves. The balance is how smokey it will be at idle and slight throttle but with your faster spooling turbo you may be able to get away with it. Also as Dave says maybe the fuel pin is turned to the mildest setting. Turning that and adjusting the smoke screw can accomplish similar results at idle and minor throttle input.

The other thing could be the throttle arm itself if there is a decent amount of play in that spring and pin/stopper thing on it. My spring and pin have been warn over the years so I flipped the spring so that it would ride on a different part of the pin/stopper to close down the gap caused from wear.

I'd drive it first before making any adjustments so you can get a baseline for performance and real readings from your gauges; boost and egt. Once you have some gauge results that can help tell us what's going on.

Different settings on the same injection pump can make a difference in sound so there would definitely be a sound difference between different pumps. Yes, the turbo also plays into that.

X2 ^^^^^^^^

but I didn't see the big smile on your face .. !

I'm just running an H1c with a 12cm2 housing.

 

[davegonz]

Also sounds like your idle is set pretty low which may account for the throttle lag. Do you have a tach hooked up? A Tiny Tach is cheap and easy to install.

 

[Jason Andrews]

X2 on turning the smoke screw in first which should pickup idle. Drive and record differences, then try turning the full power screw a little...which will also increase idle speed

 

[Welltech]

That thing sounds BAD ASS! Congrats.
