Pros and Cons of the 2v 4.6

Umm...:rolleyes:

Not sure where your info came from??? 4.6's hardly ever blow head gaskets...even under boost. IF one did pop a gasket, someone most likely had an EFFED up tune, injector, or other issue that contributed to it.

2V's are however known for tossing plugs with the 2VPI heads on occasion...mostly due to the fact that they are barely held in the head with 4-5 threads for the plug.

Here's a pic of mine after it took place UNDER BOOST...at the 1000ft mark at WOT doing a 1/4 mile run. Most of the time the plug just strips the hole for the sparkplug and guys repair it with an insert.

Here's what it did to the coil:

The Plug:

If you really want a 600-800RWHP 2V motor, you can avoid this issue buy buying some of the new TFS heads as they are designed much better, flow great (even better if ported) and the spark plug holes have more threads. And of course some good blower cams.

E85 is awesome for boost and racing cars, just hope you can get it easily and have sources close by. To get 600-800rwhp on E85, you better be prepared to install one hell of a fuel system since E85 requires MUCH more fuel than good old 93 Octane.



Want an idea on costs? Here's mine:

DSS Super Mod Longblock motor with Polished Ported stage II heads, Crower Camshafts, Forged Pistons/Rods, Cobra Crank, 7QT Canton Pan, Spec Flywheel, McLeod Clutch/Pressure Plate and other little crud= 9000$
Kenne Bell Polished Blower Kit = 6000$
03/04 Cobra Fuel Tank and Pumps= 700$
Siemens Deka 60lb Injectors= $360
Modified FPDM= 100$
Dyno Tune = 230$ *reused chip supplied by Kenne Bell*
TKO600 Tranny = 1800$

I installed all this crap myself.. so NO LABOR COSTS. I did pay some lift time to a friend who's shop I kept the car in for a while. My motor is OVERKILL for my application, it is built to handle 700-800 crank HP...and I only have a little Kenne bell 1.7L blower on it..pumping 430rwhp (about 500-510 crank). It gives me room to grow someday..when my kids are out of the house.

Don't forget you will need some decent 31 spline axles, an aftermarket differential, some good upper/lower control arms and other suspension work so it will hook. Some slicks/drag radials help too. How about some brakes to make it stop better?

Be prepared to blow anywhere from 15000 to 20000$ to get what you are seeking. Can it be done more cheaply?? SURE..there's always a bargain out there.

So.. you need to decide how much $$$ you want to put into all this, because you could easily just save your money and go buy an 03 Cobra and keep a lot more money in the bank. Even an 05-06 3V GT with just a blower will pump 450-500RWP with minimal effort on the stock motor...and they come from the factory with 31 spline axles. You could build a couple quick Fox Body cars for all this money as well.

Good Luck with your moneypit. Hope I didn't depress you too much ;)

newer 2v heads have 8 threads in the sparkplug holes. My 04 has 8 thread heads, these don't blow plugs.
ARC.. any idea what year they started that?? It was into the romeo years..but I always thought it was after 2002?? I thought Ford started it on the Lightnings because they were popping plugs like popcorn?


BEGIZZLE... Notice OX's blower is a Novi 2000. It's a great blower kit with the available intercooler that flows a lot of CFM for the money..and it can get you to the HP range you seek. I've installed a few of them as well as many KB and Vortech kits and for centrifugals..I personally feel it's one of the best kits out there. I've even had an S-Trim on my own car at one point. If I had to do it all over again from the start...a Novi 2000 would be in the plan. I'd do a turbo kit if I didn't have to deal with friggin emissions.

Hello,

Here's one below that I found:

One thing you should know about the Novi 2000 kit is see the big honkin blower in the pic above? The intake tube attaches to that to suck air in. Well that tube BARELY fits between the blower and the factory radiator. I've done installs of this blower on a car where the customer wanted a BIG aftermarket radiator and the blower tube WOULD NOT go on the blower without smacking the hood because the aftermarket radiator was too big and in the way. I think it was a fluidyne. The customer chose to run an 03/04 Cobra radiator instead. Of course something could have been fabbed up. This was the simplest solution..and the 03/04 Cobra radiator was cheaper so it saved them a little $$$. So.. just giving you a heads up to watch this area for clearance.

Another pic of one. Notice how the inlet tube is riding UP over the radiator.

Ox..

Looks great. I noticed the feed tube for the blower looks different than the last Novi 2000 I did (a few years ago).. Any clearance problems with that now with an aftermarket radiator? Just curious if they changed the design..
