How much the block can stand.

[kert0307]

Forged crank with some cobalt and nickel alloys mixed in there...


edit: This might be a great opportunity to perfect the DEI (Direct Exhaust Injection) technique.

No way you're gettin there without boost and a lot of it, this then requires new high flow heads, headers, bigger injectors . . . you could run the math but i dont think its possible

Could always get a Supra, ever see the videos of the 1000hp Supra?

IZwack - Ive got a set of those Formula 1 OHV heads on mine...TOTALLY worth it

While we're on the topic of an 800 HP OHV...I bet I could build a badass A4LD thats good for 1,000 HP if you're interested.

 

[4x4xbrian.com]

better wrap that a4ld with a flak jacket, or you might put an eye out. LOL

 

[Willard]

C'mon guys, stop shooting him down so bad. 800hp probably isn't possible but with enough cash I'm sure you could get some ponies out of a 4.0

For starters check this thread out, these heads will make a huge difference:

There is info here on the "C" transmissions. You may want to a search. One of them will bolt up, but requires a bellhousing from a different trans. Is your truck a 4x4 currently?

 

[John_Rock]

Dump the V6 4.0L and get the Aussie straight 6 4.0L turboed...
You might be able to fry some eggs on the exhaust.

Holy header.......

 

[storlied]

Yeah.... jesus....

That thing scares me... haha..

I think you could squeeze 500 out of the 4.0L. You would need to have the BEST parts to do it though. And by best I don't mean expensive, I mean close to perfect in craftsmanship. Low drag internals, high flow polished ports, headers, exhaust and forced induction. I would Supercharge it rather than Turbo but that's just my preference. Bore work is really not an option. 4.0L is just a heavily bored 2.6L/2.8L/2.9L. When you are done with it, it'll be killer though.


And I believe the C3 or C4 (Can't remember which is in it.) out of a '86-ish bronco can be bolted up rather easily.

 

[FROADER]

Holy header.......

That's what she said.



Just went and did another pull after work. Didn't even bother with a tire block/straps or a fan in the front to keep it cool. I think that effected it, because I only got 722 @ 1920rpm this pull.

BTW I didn't know my hood light still worked!

C5 was stock 3 speed tranny found in a few 83-86 Bronco IIs and Rangers. It is similar to the C4 with a few internal changes like a lock up clutch in the torq converter.

I stand corrected. Thanks for clarifying.

LOL. I'm reminded of pictures that went around recently of a certain black Grand Cherokee at the drag strip...

 

[4x4xbrian.com]

lbarr, I guess I missed those pics lead me.... I need a good laugh

If we're going F1 style, and retaining the stock OHV BLOCK (if I read the 'rules' correct)

Start with the following:

Brand new billet aluminum heads based on the 2.9L 24v Cosworth Heads (yes, it's a DOHC head that bolts to the OHV)
Billet Crank
Titanium Rods
Billet Pistons
Carbon fiber intake
Billet 4 bolt Caps

Fill the block to the bottom of the water pump holes with HardBlok Block Filler,

Then spray it with 250 shot of nitrous, and I think it is POSSIBLE to hit 800 HP at the crank, spinning 7-8k.

Dont forget to throw in a set of standoff injectors for good measure and high RPM and CFM goodness!!

 

[Masterd]

The heads, and the rods/caps would probably out value the entire truck

 

[Spdrcer34]

Are you kidding me...the INTAKE ALONE would cost more than the heads....

Have you seen the Intake on an F1 engine? I'm not SUPER impressed with the F1 cars...300hp @ 16,000 rpms..seems like alot of wear and tear for only 300 hp.
