Gary,

Maybe I missed it previously, but if you want decent efficient power, have you considered forced induction? Not dirty old "roots style" blowers but twin screw, centrifugal or turbo charging?

There's been a few forced induction Fords over the years, so you could continue the Ford theme.

Or do you want just the simplicity of N/A?

 

Again, I'm blind, or crazy.
Or BOTH!
I glanced at the second chart and did not even see that the comparison is with an intermediate length rod.
I will go back and correct that.

5:00 AM here now, and I am catching up w/ the forum.
Constantly checking my CP for thread replies is beyond me.
No solace in knowing that I am not alone.

 

Brad - We haven't talked about forced induction, but I don't think I'm up for that. While I'm impressed by jstits's Ecoboost and my wife's bi-turbo'd oil burner I don't know anything about installing turbos and am not ready to learn on this project. But thanks for the suggestion.

Jim - Not to worry. And I fully agree - using the CP to watch for updates wasn't working. But looking at my in box this morning it appears they may have found the clog and removed it. I dozens of messages that I'm wading through, and many of them take me back to the same place. Quite confusing. But, Dad always said "Misery loves company" so there's some consolation that I'm not alone.

 

I know the compression numbers need to be pretty low to use a boost set up.

 

Depends on the motor. 9.5 is about the highest you want to go for a forced induction path. For our trucks, I prefer a supercharger or a twin small turbo. NA and superchargers deliver the best low end. Turbos tend to be better for top speed. I plan to leave my M NA.

 

You've not driven the MB GLK Blutech. 369 ft-lbs from 1600 up. But, then it's diesel so power would be at low R's.

Anyway, a potential mod on this truck would be EFI, but not forced induction. So I'm building a good solid base from which I can add injection later - if I decide to do so, although I'll probably be happy with what I have and move on to the Bee.

 

And then onto Janey's truck.

If you decide on EFI for Dad's Truck, you could always pull a 'sneaky Pete' and run some juice into the underside of the manifold.

But again, you'd have to build the engine up with that in mind.

 

Now THAT'S a good idea - call it Janey's truck! Why didn't I think of that.

As for juice, I'm not sure Dad's truck is going to need more than what the current plan will give. Everyone I've talked to, as well as the suspect Cam Quest runs, say that 500 ft-lbs is easily gotten from the combo I'm planning. And that seems like a good place to stop.

And, as an update, I sent Tim a note last night saying I'm ready to finalize the details and want to order a complete kit, inc heads. But, that I need a bit of help making that decision although I'm leaning to the Aussies. We will see what he comes back with.

 

I was referring to gas motors only. Diesel is a whole different animal. EFI is a smart upgrade.

 

Most of the Mustang guys I see doing boosted builds are always looking to be around 7.5-8:1.

 

Import motors tend to run at about 9:1 for turbo applications. Especially the Nissan KA24DE. CR max is largely dependent on quality of build and engine life expectancy. Guys have been running 9.5:1 under 7-8 psi boost for years. Others pop the head at 9:1 because they run too much boost. Forged internals and more precise timing and fuel regulation allow higher compression in forced induction. For a carb setup, probably want to keep it lower to account for the less precise fuel delivery.

 

We were going into Tulsa today so I went on over to STK to chat with them about the machine work for the engine. There was Stanley in the back doing something and a young lady, probably his daughter Kayla, boring a block. She really seems to know what she's doing and we worked through many of the details regarding the job.

I did ask about the Keith Black pistons, and Bruno is right - they don't like them. Supposedly they "pull the skirt off", whatever that means. However, since Tim's pistons are essentially the only game in town we agreed that's pretty much all I can do. And, as she pointed out, Tim seems to have had good luck with them, so maybe it isn't all KB pistons and the ones they make for him are good.

So, I need to proceed on two fronts. First, start pulling Dad's engine apart and get everything ready to go to STK, which includes the block, crank, and rods. Meanwhile I will work with Tim to nail down the exact config, including heads, cam, etc. What am I missing?

 

Where were they located Gary. Bobby had his operation way out South in Broken Arrow. He was around 81st and 177th E ave. If he was there when you were he was the guy standing about 6'4" and weighing in around 380lbs. They call him Big Bobby for a reason, I am not sure what it is though.

When I bought all of my parts for the Bronco build it came with a set of KB pistons. Bobby scared me into selling them and getting something different. The funny thing about it was I tried to list them at the Corral in the classifieds, but mistakenly listed them in the Windsor Performance Forum. Just as I posted them I X'd out of the page and realized what I had done. I opened it back up, logged in and went to the post to copy it and a guy already claimed them and bought them LOL! I should have asked for more money!

I ended up with a set of lightly used SRP forged free float pistons that were sitting on shot peened rods with ARP rod bolts in them. I got those for $250. Bobby looked them over an gave them the thumbs up. The pistons new were $500 and just imagine what the guy had in , machining the rods for the slip fit, shot peening and buying as well as having the ARP bolts pressed in. I hate for the Bronco not to be running correct because it has some sweet hot rod parts in it.

Hopefully after the ignition gets overhauled it can be right!

 

They are at 1100 E. Memphis. According to Kayla, Big Bobby has "moved on", and he certainly wasn't there today. Just Stanley Morton, his daughter, and presumably his wife who was in the office.

Yes sir, the Bronco's got some hot rod parts. Gotta love those headers. Seriously though, sure hope you get it going well & soon.

 

Yep, that's the place.They did 2 motors for me there. One of them was a boosted motor running 18:1 compression and around 35-40psi of boost at times.
