Marauder down but definitely not out!

Yes I have read about them in the Mustang mags. The price is right John. And it has all the necessary components necessary to produced a high horsepower, solid Marauder engine....hummmm, maybe I may have to get one too:rolleyes:
 
BillyGman said:
John, the only thing I wonder about concerning that engine, is that it has a cast crankshaft.
John, Billy is right. I have not heard of a Ford Racing Cast crankshaft. Although it is rated (so they say) at 600 HP. I will make a couple of phone calls and let you know.

Yes, the cast crank was an issue. I've settled on this one:

An an ArtCarr transmission for 2K and then I get Claude to send me kits for all the mods for the line lock and I'll be all set.

John
That sounds better, and for under $3K, that's a good deal. BTW, is that a distributor I see in that pic that's near the driver's side cylinder head? :confused:
 
I'm sure it's just for show on the pictures. hehehehe. Doesn't look like the turbo goes into the intake either!

I just want the short block which is all they are selling. The crank trigger etc from mine should bolt on with my heads and so on. That is, provided my heads were not damaged as well. No telling till I get it pulled and start the science class dissection.

I still haven't decided on compression ratio yet. I am leaning on leaving it factory but I want to see what those who have lowered theirs say.

The parameters for the final product are to be right at where it was, RWHP wise, when it was dynoed without the NOS. I will want to put a 100 shot on top of it -after- it matches, no more.

If 9.5:1 gets me where I want, fine. I've always thought that 10.1:1 was a bit steep to supercharge safely, but it always comes down to just how much boost we are talking about. That has been proven.

Cheers!

Ford Racing cast crank, P/N M-6303-C46, for Romeo blocks, 6 bolt. $159.00
 
John, I bought my forged motor direct from Modular Mustang Racing and had no problems. My compression ratio was 9 to 1 and I was not happy with the results. IMO I would not go lower than 9.5 to 1 on such a small displacement motor and it is in a heavy car. If you run 9 to 1 in your compression range than you will need 15 PSI to get to around 500RWP and than you have a major problem with the 6 rib belt set up. It will slip. I know first hand.

Good luck in whatever route you decide to take.

That sounds like excellent advice. It does not appear that playing too much, or at all with the compression ratio on the MM has had the intended favorable results.

Regardless, the options you keep looking at John are good. I am hoping along with you your car when it is done meets or exceeds your best expectations. :2thumbs:
 
Update:

After doing a lot of research and conversing with fellow members, I've settled on the following:

* Cast iron Cobra block, new over-the-counter.
* Forged Cobra 8-bolt crank
* Forged Cobra rods
* Forged CP Pistons at 10:1
* Factory heads with custom porting
* Custom Comp Cam cams to match heads from flow bench
* Same ProCharger P1SC at same 13psi boost.
* Final dyno tune to add 100 shot of N2O (because it will now take it)

I'm just starting to get pricing and such together, and ETA on completing is still unknown as the builder is currently working on other 4.6 projects. It may be 30-60 days before I even get in. I'd like to see a January 21st completion date because it's my birthday. As I get more info I'll pass it along.

Cheers!

John
 
Looking forward to updates and can't wait until it is done. I definitely want a ride in it next year!!!!

I finally got some time to scan the dyno chart of the tune...

dyno-100405.jpg


I was and still am totally satisfied with the tune I got. I am really looking forward to getting the motor pulled and disassembled so I can turn the bare block into a polished coffee table under glass!

John

John your dyno chart looks extremely similar to the tune I had with Scott Beer at Diablosport. Just a few HP & Tq differences. Anyway, I will be watching closely your engine build and probably PMing you often once I get started on my engine build this early spring. Although it was tragic on the engine loss, your new found power will be worth the expense.:beer:

John we have a fully built set of Fox Lake heads here these have bronze guides fully massaged heads titanium retainers and they have a good cam set up call me if I can help
 
John, I think you have made a wise decsion in leaving your compression near stock. Like I said before, I was not happy with my choice of lowering my compression for everyday street driving.

Good luck in your rebuild process.:)
 
"Are you suggesting we throw money at the problem?"

Knight: "We must build a large catapult and hurl the largest of projectiles at the sloth."
King: "What sort of projectile do you recommend?"
Knight: "This... (large bag of riches hits the table)"
King: "Are you suggesting we throw money at the problem?!?"
Knight: "Precisely.."

I love that IBM commercial. So I finally put my money where my sloth is.

Update: 11/23/05
I've been doing research for 6 weeks now in exactly what to get to replace the "window" block in my car. Let me tell you, if you talk to 6 different people you will get six different answers. The important thing is that of the knowledgeable people I consulted, none of them are wrong. When building a motor, there are many schools of thought and no one of them is right or wrong. I'm prefacing this update this way so that there will be no hard feelings with everyone that has chimed in. I'm going to build this motor the way I think it should be done and will report on progress and performance numbers when complete.

Because I was able to actually get it on a dyno -before- airing out the crankcase, I know how it worked and felt. I'm not going to build an identical 4.6 so this really won't be an apples to apples comparison. Well, in a way it is but I'm putting a lot of non-stock parts back in too.

OK, enough ego stroking, here's what the bag of riches bought today:

MMR Street Mod 900 short block; New cast iron Romeo Cobra block, Kellogg Forged Cobra crank, Forged Manley rods, Forged Manley 9:1 pistons that will be coated, ARP Main and Head studs, Cometic head gaskets and a set of DR Fox Lake heads. Dennis is putting together a list of ancillary parts such as 60lb injectors, new fuel rails, twin focus fuel pumps and I'll be getting 8-AN line from tank to engine with a BAP. I'm sure I left a few parts out here and there but I'll be making an exact list as the parts arrive and the build proceeds.

I'll be looking to go to a smaller pulley than the 3.6 I now run so I'll be pushing the boost up to around 16psi on the ProCharger. After a lengthy discussion with Dennis on the heads, I am confident that the cams in them in addition with 3 more PSI will more than make up for the drop in compression to 9:1. Again, when finished I'll have another dyno session done so we can see if my plan comes together or not. My goal is to complete this by my birthday in January and then put it back away for the rest of the winter. (Hey, its still a Marauder!)

I'm sure that I will be tapping a few of you on the shoulder as I progress through this for more advise and suggestions. Just don't be offended if I don't use all of them from all of you.

Again, I appreciate all the time and effort everyone has offered while digging for my solution.

Tomorrow is Thanksgiving, so go eat some Turkey!!

John, looks like you have been doing your research;). In my opinion you have selected excellent choices overall with your components. I am working on my new engine research/project which will be somewhat different than yours. One thing I am going to do is upgrade to a D1SC. You have a year and you can trade your P1SC in for an additional $900. for the upgrade. Not to dip into your bag of $$$, but there are considable performance increases with blower design and boost levels available. Have you looked into it or have you decided to keep the P1SC ?

Either way the motor will be a monster. :eek: I will be closely following your project and I am confident that you will be extremely satisfied with the results. Can't wait my friend to see the beast back on the track next year.:banana2:

John,
Any info on why the tranny dropped out of gear and let the engine over-rev?

I agree that you're putting together a great setup, though it's not exactly the way I'm going with my buildup. Ahh, variety... it's great isn't it?
