This is long overdue for a few that followed my build thread long ago, but I finally got some proper dyno tuning on my 3v swap. I've hardly driven it for over a year and a half since I bought an '11 Mustang GT, but I'm getting it ready to sell so I'm tying up any little issues. I had originally done mail order tuning from a big name but it never worked well, was worlds better to be there on hand with the tuner as we had to sort out an issue with the cam position sensor. Anyway, my old 2v combo with (home) ported heads and longtubes, similar overall, made 264/343 after a cool-down. I was hoping the 3v would make similar torque and more hp, well, after getting it sorted out and cooled down how about 297/381???

The old results were without locking the converter, the new results were with converter locked which would bring hp up a bit, but makes the torque even more impressive.

 

Without a charger right? I recall Neil (the hp freak) made 360 hp with a 99 2v without a charger. He was running Fox Lake heads tho.

That's great for NA power on the 3V. Congrats!

 

Now it needs to be blown...

 

a set of ported 2v fox lake heads probalby flow similar to a stock 3v head.

great site for heads

neal would never post his dyno results, so the 350 - 360 figure is a number quoted over the internet......take that for what it is. he was also running low compression and a cams in the 230's duration , big for a 5.4

297 rwhp seems very respectable

 

Right, I can't recall seeing Neils Dyno sheets. The Dyno sheets are the tell all.

 

Dang! I guess so, thanks for the link BD.

 

i love that site.

head flow is where it is at.

i have an 09 z07 vette with the ls7 motor.

ls7 heads stock flow 374/219 @ .600 lift. i went from the stock cam 210/230 duration and like .58- .59 lift to a 230/252 duration .620 lift, went from 445 rwhp to 530 rwhp (tune also) little over 600 crank with just a cam swap. this is why the gm ls motor are so loverd by the hot rodders.

 

I didn't believe those numbers then, don't believe them now.... There simply aren't any (especially at that time) 5.4 2v intakes that would support the airflow and rpm necessary to make that number. Even if he had an electric water pump and every other trick not gonna happen, especially spinning an auto trans (~20rwhp less than a stick...)...


Combination is where its at.....as shown by your own example...

The best heads in the world do nothing if the other parts don't match. Likewise awesome cams and/or intake can only do so much to crutch so-so heads...

My own combo has a lot left, but I have no plans to pursue if further. A set of cams would make a huge difference....

 

Lets not get too far fetched, I believe it can be done.. -

NA numbers I trust, -

Roush Stage II
Engine: Modular Performance cast iron Big Bore..
Intake: P51
Heads: MP Stage 1 PI
Cams:MP street cams
Exhaust: BBK long tubes with catted X and Roush side pipes
Power Adder: none
Boost/Pulley: none
RWHP: 349 rwhp / 349 rwtq

Truck: N/A
Engine: Stock? Built/Forged etc.
Compression: 9.0:1
Heads: Stage Three Livernois heads
Cams: Livernois custom grind
Exhaust: Headers?/Catback?/Offroad/X Pipe w/cats?BBK without cats
Power Adder: none
Boost/Pulley: none
Fuel: Example.. 03 Cobra Tank/Pumps w/KB BAP,Modded FPDM
Injector size: 60 pound
Transmission/Clutch/Converter: TR3650 Spec Stage two
Rear Gears: 4:10
RWHP: 341 hp/309 tq

 

i beleve it to. however it needs 3 things.

1. 10 to 10.5 compression

2. an intake using a larger ports and shorter runners.

3. an engine buildier who has built several modular engines and knows all the ins and outs


the ford modulars are built like a brick xxxx house. boost is the way to go with them.

 

I agree, - man, seems like I've seen more than a few engine builder fails with the Modular.

 

jbrew, even your example with a big-bore (which isn't comparable at all) and a P51 intake that wasn't out when Neal was posting that didn't get to 360.....and it doesn't even say if that was a stick or not.

That being said I think it could be done on a 5.4 with ported TFS heads and a better intake than a P51, even ported, as it still doesn't support the rpm...very hard to make a 2v 5.4 make power up top...

 

I thought I fixed the Neal comment. - Okay, I see what your saying..

So what's the best you can~ Forget that , -I'll ask what I really wanna know lol. What do think it would cost to reach 500 HP w/great pulling torque (geared appropriately) for trailers. Like say, heavy double horse trailers on the side.

Don't get me wrong 300 Horse (around 300 rwhp blown) is a blast and very respectable (as said) for NA. I've been in those trucks, it's like night and day compared to my factory original, - specially in the dunes lol.

To reach 500 from stock I always figured between 7,500- 10,000 for a good build. - Blown of course and a 2V 5.4L. Actually, a 3V 10 might be a better start, possible cheaper, - IF, someone has a crank for it now?? The 3V V10 is an animal to begin with. Numbers close, - ballpark?

 

boy, I thought we were off track before....

3k for a shortblock, 2.5k for heads/cams, 6k+ for blower and fuel upgrades, another 2k or so for everything else that comes up not counting a built trans....no thanks....

Find a low miles wrecked Lightning and grab the drivetrain for 6k, then still need more for fuel system, tuning, pulleys, cai, etc... Kinda really depends if you are talking 500hp (~425rwhp) or 500rwhp too....

 

I know, I wasn't going to ask lol, - what can I say, had an itch.

But I included a good comment about 300 HP, an honest one, which is good for feeling guilty IMO.

Where the 500 comes in, is in 4WD. You can stay afloat much longer in that sugar sand and in the mud. That stuff can really knock down the power. Not really into the quarter mile, just would like the build to last a little longer than that.
