4.0 SOHC Performance Motor Build

[Jakee]

2000 - It's not a problem on all the builds I've seen on the 4.0 SOHC. I've got a lot of miles on mine pushing it pretty hard...no problems except for the dumb scavenge pump problem I faced earlier in the thread. (which is now fixed)

I actually learned a lot about the terlingua mustang. I admit, I had no clue about this mustang version until you posted in this thread. 2000 - basically, on customer request, they send a v6 mustang down to a town in Texas. When it's done it comes out looking like the mustang you see above. It uses the 4.0 SOHC and the guys doing the work are......I'll Let SVO tell you.

I hope the data in this thread, that I started years back, helped you. I just wish I could have done it when I said; However, I want to stay married. LOL

You did good, it's not going to be easy and there will be the "debug" stage. I just hope you tell us what DOESN'T work, if you find that. Most will not. I on the other hand have no problem telling, or typing..documenting, what I've tried and what the results were. That's what the forums are about...but the money seems to get folks. That's okay, nothing is free. And if someone really wants to do something like this, then they should do the research. So I know what you're saying.

What's the compression ratio again?

 

[Jakee]

One more thing. I always thought is was "not allowed" to mig weld on safety cages, or is that in certain classes? I know my bud just tig'd his entire dragster (100 plus hrs) because that is the rules in his class.

I agree with what you said in your original post regarding Morana, even if you did end up editing it all out. That guy makes some shoddy stuff. I haven't seen many results from Supersix so I cannot speak much about them but there have been a few things I have seen that left me questioning their knowledge and ability.

good news....

"Hey guys just got off the phone with MMR and the prices include: $700 pistons, $500 rods w/ bolts."

http://www.mustangcollective.com/showthread.php?t=35836

"Due to the large demand for forged internals we have worked closely with Manley Performance to produce a custom forged V-6 Piston and rod combination, they are made of 2618 alloy for the pistons and 4340 forged steel for the rods, this combination can handle up to 700 RWHP!! and is a direct replacement for the factory parts. The rods include ARP 2000 bolts and the pistons include chromoly steel pins, they are available in all compression ratios too!!

How about a crank? For that kind of money I would be shooting for more cubes. The 302 stroker kits run about $750 for a balanced assembly, crank/pistons/rods/rings etc.

The stock parts dimensions typically are not ideal for high performance. Meaning the pistons are very tall, they have a lot of meat in them, which makes them very heavy. A nice competitive 302 kit makes more power just from the weight savings.

I know I've asked this before, but has anyone checked on the differences in dimensions between the 4.0 and 5.0 engines? There are so many various 302 combinations of pistons deck heights, you might find one that can be fit into the 4.0, if you can come up with a good crank. I think the crank might be the tough part. The best available crank besides the custom pieces like SVO etc use, may be to turn down the Ford crank.

Let's see some pics of your build. Watcha running?

 

[Jakee]

up to 12 LBS of boost now. Let's see how long it'll survive. So far so good...

Impossible!!! According to the guru's at Rangerpowersports your engine will have detonated worse than a volcano 6 psi boost ago! :

 

[Jakee]

I guess I'm lucky. So was James and so was all the mustang crowd that has done this..LOL

Guess what? I'm in Texas where it's been 100 plus outside for a month straight! And I'm upping the boost! hehe

I am re-tuning as I add boost. It's pulling hard as heck.

Yeah those RPS guys are a hoot! Some of the ignorant tech talk that comes out of the mouths of people over there makes for great entertainment. Like the guy who is trying to fit an Eaton M112 onto a 3.0 V6 Ranger....because bigger always equates to better.....Uuuuuum, yeah......

Jakee / Still waiting to see that thing run especially now that we are getting back to cooler weather!! I googled it and you are two and half hours from Little River Academy dragstrip,
http://www.littleriverdragway.net/
I am about one and half hours away, Ill even pay your entrance fee just to see it in person!

Looks like our local track just shut down last week so I may take that offer. This local track has been closing, reopening, closing, reopening for awhile now.

I'm currently adding an exhaust cut-out and meth which should get me in the 12's. (crossing fingers)

 

[Jakee]

I don't know how far you are from this but I'm going to try to make this. I have a bud that is running his dragster for the first time here.

 

[Limited02]

Does your Sport have adjustable headrest???

 

[htrdlncn]

SAR is a bit farther for me as I am NW of Austin and I usually go to run at the track,
so I try to avoid big events as you usually get very few runs in

 

[Jakee]

I would also like to report that 12lbs is going fine here. The ONLY mishap I've had was blowing the intake pipe off the TB which damaged the powder coat finish and gave me a bit of a scare. That is it. I need to make it a habit to check the tightness of the turbo clamps when the temp changes. Maybe once a month would be a better.

 

[Limited02]

The reason I asked if you have adjustable headrest is because you can easily stick a digital camera between the headrest and it makes a perfect mounting point for the camera. I'd really like to see an interior shot of the track when you run. Only problem is you can't press down too hard because you'll "stop" recording

A few members are talking about a small meet up here in KS and possibly running at the strip. I haven't done anything new so I'm not sure if I'll run. Was hoping for 14's this year, but it's not looking like it'll happen. Goodluck on hitting 12's!!!

What are the main changes since you last ran mid-13's???
