...The worlds largest log manifold.

This is a 4.0L jeep manifold that I've been working on. I'd like to thank Sam for taking so much time getting this flange made for me . Keep in mind, that we were not looking for overall flow here. Durability and a quick spool was the priority in making this. Theres not much room at all in the engine bay, so this is also really the only manifold option available.

Crappy pics:

Never seen one like that before! lol

 

You should post up some after-install pics when you get there

 

Those inline 6's are slow as hell but when in the dirt it doesn't really matter! as long as you got the torque....

what are you guys going to doing with this setup! hill climbing or something?

Definetly. This is actually for a customer's cherokee. He has a built 4.5L stroker motor. He's not sure what turbo he's going with yet, but it will be interesting to see how it spools a small T3. The 4.0L's have a very flat power band, and die right around 5K, so it will be interesting. His setup will basiclly determine whether or not I go with a T3 or T4 hotside.

Actually, they have some pretty damn good power. It's a pretty large engine especially for how small most Jeeps are, but most of the power is off idle. I'm hoping the turbo setup will increase the mid to top range power.

Theres no real goal with the setup. It's just to have more power with large 33+" tires, and have some fun on the street at the same time.

 

Man that is one hell of a log , lol looks good

 

Haha, no topmount?? lol j/k. Looks dang good. The outcome should definately be interesting.

The new jeep cherokees are going to be freakin nuts. They are coming stock with Twin Turbo'd Hemi's. 0-60 in 3.1 sec... (car and driver mag.)

 

Those inline 6's are not slow as hell. Faster then a 280z.

They put out good power and scoot like a muthereffer for being in a suv....

Now they arent like the new 2007 v6's puttin out 270hp, but they are still quick.

 

Holy hell, Bryson! hahaha that manifold is crazy!

 

Hahahha that's baddass.


Now go prep your steel before welding noobert

 

Bryson, why not go the 505 route? It would be so much easier.

 

No holes in the flange for mounting...how come?

My other question is, how come you never just run everything on a wire wheel before welding. I know it doesn't make a difference, but I just like stuff to have a little blingy when it's done....makes me feel warm and fuzzy inside.

Good work though...funny thing is I am buying a Cherokee on Monday. Might end up needing one of those flanges...lol. I personally would probably go with a custom mounted M60 though. Seems to make more sense for a truck that needs some low end grunt.

 

i got an 87 cherokee with the 4.0. i wouldent say its slow as heell, has alot more punch than my 4.3 vortec s10. regardless, it needs a new rear main seal cuz it leakes like a mother.

you can call that manifold logzilla

 

Thanks guys! BTW, thanks Rich for putting the short 2.5" 90's up on the site. These new honda manifolds are going to be great. I'll have some more info posted up in a couple weeks

I always prep the steel. However, I only preped the joints on this manifold because it's getting coated.

I absolutely hate where they put the turbo. Everything of importance is on that side of the engine bay. I'd also rather not half *** the setup (like the 505 kit). Another factor is that the factory exhaust manifold is known for cracking, so it's beneficial to replace it with something a little more durable.

Theres 2 holes at both ends. The 4.0L has the intake manifold on the same side as the exhaust, and both manifolds are clamped down using the same bolts. It uses large cone washers to clamp the tips of the flange.

But like I said...I always prep the manifold, and I always use a wire wheel! lol. I don't know why you guys don't think I do.



But honestly, I'm thinking a decently sized T3/T4 will spool up great on this motor. Put a GT30R on there, and I don't think you'd be able to tell the difference between a SC'd 4.0 and this.

I might end up going with a P trim T4 though to keep a decent gas mileage by staying out of boost in low rpms. It will stay my DD, and even now at modest 20mpg it kills me.

 

looks good to me.............. as long as it works than ur good to go.

 

yeah boi! bryson owns!

I don't skate, but yes thats where I got that from. I've been typing that for the past 5 years.

 

I just mentioned wire wheeling the pipe because of the writing still visible. I see though you said this one is getting coated, so makes sense not to prep them entirely.

I recalled seeing another mani of your with the print still on the pipe....guess I just assumed all your stuff was that way.

Still looks good though You've gotten alot better over the past 8 or 9 months.

 

Niiiice. I saw a 7 second mustang last season (street car) running a log manifold like that. haha

 

Nice work man

Any pics of it on the engine yet?

Not yet. The customer is going to be using an HX35 turbo though, so I'm really excited to see the results of this. I have a 99 cherokee sport, that will eventually receive this same setup.

 

what do jeep guys do for engine management on light boost?

i've seen a few full standalone setups on a couple of wild jeeps at the dunes, thats about all though..

thats gonna be sweet

 

It's hard to say what most guys use right now, considering there are VERY few of these setups out there. However, we've found the splitsecond FTC1 unit works fairly well. It's a piggy back unit, that works kinda like a standalone when your in boost. The stock ECU basicly has no idea anything is different, so it drives pretty much like stock. It also has real time data logging, and table tracing which makes it just as easy to tune as a standalone.

Most Jeep guys right now go with M90 SC setups. They work well, but I really think more of these guys will start to go turbo, when they see the power these things can make, especially for far less $ than most of the SC systems on the market.
