I only have 3 things to say:
- I wasn't talking about a straight line, so on road events, same suspension/tires setup, stroked engines N/A vs FI, you might still be looking at their plates... now, onto the cost...
- 3K? Really?!?! a 9000rpm rotating assembly, pistons, heads, and just about everything that was mentioned in this thread, for 3k? well, I'll stay tuned to the thread where you can show the rest of us how it can be done. This will definitely bring to light that the companies out there are charging us an arm and a leg, armed robbery! if someone like you can get it done for 3K vs the 50K that Bullitt995 guessed.
- It's still freedom of speech, you are free to say whatever you want, but with that freedom comes responsibility, so the owners of the forum have to excercise that responsibility if we don't know how to do it ourselves.

The problem isn't necessarily the rotating assembly. Although there will be decent money in that. For a 9000 rpm effective range you need a lightweight, yet strong rotating assembly. This means billet pieces pretty much throughout which gets pretty expensive.

The biggest issue is the valvetrain. The mod heads were never designed to even need to spin that high, and there's some design issues you'll run into there. It's not just about the springs either. The roller followers are a problem at this range. I'm not a valvetrain expert by any means and I don't know the specifics about the roller followers on these engines, but from what I know they are hydraulic followers much like you'd find in a hydrollic roller cam setup for a pushrod engine. These tend to "pump up" with rpm and as the speed increases they don't have time to adjust their lash and start bouncing over the cam lobes. This causes valve flutter and well...you get the picture. Higher pressure springs help somewhat but they also tend to exacerbate the problem when it does occur.

Realistically you'd need to modify the heads to take solid roller followers. Plus all the fun you have with continuous adjustments to those solid followers. I'm sorry but I do not want to take the valve covers off these engines any more than I have to. It's not like a big chevy in a boat of a car with oodles of room.

You'll have to likely go with a custom one-off intake manifold as well. I'm not certain of any aftermarket pieces that will flow enough at the rpm's you're wanting to even be worth trying it. So there's more $$ in fabrication and testing. Either way you're going to kill the power band below probably 4000rpm. The short runners will see to that.

I mean, it's a cool idea, I just don't know if it's really practical. Even for a road race car. You're going to have to have so much gear in the back that it almost defeats the purpose.

If I was building a project like this, I'd be looking at a 4 valve motor first off. I'd go with a teksid block with billet rods, possibly a high quality cast piston to save weight. ARP2000 hardware and a solid bearing set. I'd then have a set of Ford B heads (found on the 96-98 Cobra) massaged thoroughly. These heads work the best in high rpm applications over the C heads in the 99/01 Cobra's and the 03 updates.

I'd run a sullivan short runner intake on top of those heads with a cam profile to give you peak power arouns 7200rpm. Then spin it to about 7800. You'll likely need to go with a set of beehive style springs, and of course you'll need hardened valvetrain items as well. billet oil pump gears with a high capacity pickup and pump.

Make sure the rotating assembly is balanced within a couple grams (you should shoot for within 1 gram) and you've got a quality harmonic balancer attached to the crank. Add a lightweight flywheel, pressure plate and driveshaft and finish it off with a set of 4.56 gears.

That would be my suggestion anyway, but I'm not you.

I don't necessarily think it would take 50,000 to get what you want, but it's certainly going to take many thousands over simply building a motor for stock rpm limits but to add power on top of.

Oiling is what I was mearly asking about. Then again a dry sump system for mod motors can be had for about 2500bux with pumps. As for any oiling issues after that, gotta pay to play.

9,000 rpm is well within the specs of a good forged set of pistons & rods.

ITB's are arund 3k.

Now as for fuel system, a full return style fuel system can be had for less than 2k with triple pumps in the basket.

It's been awhile since I've seen a post that made so much sense on the Mustang Source. Thank you for a breath of fresh air. If you really want to make a cool high rev mod motor you go de-stroke a 5.4 and spend your life savings on some heads and the valve train.

By the way, a billet rotating assembly (which I have personally spec'd out) costs A LOT. The crank alone costs about 5k if I remember correctly.

It's fairly clear I've gotten to you. Most of the technical/informative posts about my car are made by svopaul. Anytime he has referred to a stroker S197 in his shop or "the turbo car", that's my car. And you're right, I do only post for my personal entertainment. I keep most of the details about my car and my build to myself because it is used for grudge racing but I guess you don't understand that.

I kept your quote about small man syndrome. It was the most humorous part of your post. If I had small man syndrome, wouldn't I constantly post about my car and everything it does, and how much money gets poured into it? It's nauseating to see people post every time they do some mundane thing on this board. Oh you changed the oil? Good for you. You figured out how to read the directions and install something? Wow, I'm amazed.

Thank you, I appreciate the info greatly. Love the fact that your giving REASONING behind your thoughts. Also appreciate the fact that you talk about the tech behind the scenes. Much appreciated.

FYI a mediocre set of forged pistons, will have a typical max velocity of 25 meters per second, to be considered reliable. @9000rpm keeping the 90mm stroke of the engine the piston speed is 27 meters per second, a good quality set should survive this type of thrashing. There are engines out there hitting 27 meters per second or so in piston speed FACTORY. Not to mention if you destroke a modular to 88mm from factory 90mm you can reach a hair over 9k rpm while still being within spec of pistons @ 24.93 meters per second. Mening the modular goes from being a 4.6L engine to a 4.5L engine. A bit of boring out should gain back the lost displacement.

JUST an FYI, as far as what you speked out. Don't really care, there was a time that you were going on and on on how you cant have a nicely built short block for less than 10k, seems the market has changed with quality forged short blocks going for less than 4 now with 5k or so installed. I agree with 70MACH1OWNER on this, you must have a small pecker

So now you're just trying to hold that the pistons will work? You've argued nothing I've said. You're talking to no one. There's a big difference between billet and built as far as how much a shortblock costs. If you get one in your car for 5k, which you can do, it won't do any kind of high RPM or even be able to handle big boost.

Tell me jaguar, how many built shortblocks have you paid for? Ever had one in your car? Seems to me like you're talking out of your ***. Just because you can go over to MMR's website and look a price doesn't mean you know how much stuff costs.

Have to say this has turned interesting. I am not a engine building expert, but I would think what you want would cost a nice piece of quip. Just saying.

So you personally spec'd out a crankshaft that costs (To the best of your memory 5K). First off I would think if I did that I would remember the cost. Did you also personally spec these out?



Why not just move on to the "Big Boy's Website" and attempt to convince them of your superiority? You are boring us Peons. I also suspect since your claim SVO Paul has posted everything about your car it should be easy for you to come up with some links to those posts? But I am sure that will be a problem for you also. What a TROLL! Oh BTW I am going out to change my oil.


I also want to personally apologize to the original poster of this thread and everyone else (but butthead) that has posted in this thread for my posts toward Jackass or I mean Jake. He is right he must have gotten to me. His arogance and total disrepect for everyone's opinion on this site has been well documented for a long time. I just chose to call a ***** and *****. After this post I am done with him. I only hope he keeps my quote in his signature for a long time so even the newbies that come on board next week or next month wonder WTF is up with this *******. Again I am sorry that I misdirected this thread. Please get back to topic.

You remember the turbo car that C&L tested their intake on? The post that Paul made and everyone went off the deep end and the thread was deleted? That's my car. Here's some other examples that still exist:

https://themustangsource.com/showthread.php?t=475801
https://themustangsource.com/showthread.php?t=472957
https://themustangsource.com/showthread.php?t=460888
https://themustangsource.com/showthread.php?t=461069 (you even posted in this one)

This is all really old stuff on the old build. And a really old picture:



But I guess none of that counts. It's not really fair for me to post "how-to" stuff or any kind of technical info seeing as I'm not the one building the car. Get the good stuff from the horse's mouth.

I don't know much about the techy stuff...not involved in any of the work on my car...but I know quite a bit about spending money to modify the thing. It's on its 3rd build and I have two budgets. One for modding and another for replacing all the krap that's going to break sooner or later. It always costs more than you think, particularly if the build is on the cutting edge...as in doing something that is somewhat untested or untried. To be safe with extreme builds, project what it will cost and then double that figure.

So you are saying that I can have that 9Krpm redline engine for $6K? I'm still staying tuned, I want to see that wonder machine being built...

Are you still using the C&L Manifold in your car? if you are, what are your thoughts? I have one of the original runs in my storage that I have to send to C&L to get remachined...

I don't think the FRPP is going to make any more power than the C&L, where I think the FRPP will surpass the C&L is weight.

Nope. The projection is about the build...not a part of the build like the motor.

The build would likely include major upgrades in fuel, transmission, rearend, intake manifold, and all the other upgrades needed to support the increase in boost/power. From my own experience and listening to others that have done extreme builds... you go 3 steps forward and often 2 steps backward...and all the time, the meter is running.
