After making a couple mini-rams, I really decided to move my jig and try to gain a tad bit of height. I had a guy come to me that wanted to be different (don't so many of them say that). I had this collector lying around that I cut a while back, and his budget was for a miniram.

So, to make the story quick, I decided to move my jig, then make a mini ram style mani, but use this other collector. I think it worked out pretty well. There's a few changes I'll make to simplify the runners on the next one, but for the prototype it seemed ok.

Whatcha think?

 

Looks interesting. I agree that some changes to the runners are needed.

 

Always goood to move outside the box. I have heard alot of note on that collector design and the turbulence it creates right at the turbine flange as cyl 1=4 are damn near flowing into each other. All the cylinders seem to be crammed into one another at the flange point.

 

I have one of those collectors sitting and collecting dust for about 2 years now. I should put it to use.




BTW Manifold looks good.

were you making a supra collector and get caught up in the moment ?

LOL, I was bored and took the idea from the bike collecotrs used for ground clearance. I was going to make a a/c friendlly short ram manifold. But I ended up just scrathing the idea.

yeah, I agree the collectors are not ideal versus the standard radial style. I just felt that the goals of mani's in this price range are more geared to outflow cast and log style mani's, but still maintain function and reliability. The oil drain height seemed to be a pain to people, so if there is a theoretical (since noone has truly flowed a mini-ram versus this) loss in flow I think it's offset by the improved drain height.

This is going on an Integra LS setup with an SC61 though, so I'll have dyno numbers coming from a local Mustang dyno. I guess the capability of that turbo mani will be revealed.

I am also gonna build a mini-ram using that same jig, so maybe a comparison then can be done.

 

I bet if you made a slightly diff collector you could line up the two outside runners so it's a straight shot to the collector after the first bend thereby eleminating two weld els and two welds from the design. Then it would really be cheaper.

Yeah, that's exactly what I planned on doing. I had less spread on my earlier collector jig location, but it made it tough to get that style collector on a t3 flange. Once I finished this one I saw that if it was just a little less angle it'd point right at each port, so I'm gonna work on that. In addition, if I do a Dseries with this current angle it'll be even more difficult, so yeah, you hit it on the head.

 

Wanna sell me one of those collectors?

Seriously....? We're not talkin mill cut stuff here...I'll have to fire up the HF bandsaw. I got no gaurantees on dead ***** precision here....

 

Shoot me a price without a flange welded

Also what does one of those look like with the flange welded onto it?

If you look in through the flange, is there a lot of blockage?

 

nevermind, reading owns me

Well, I did work to the flange. The opening is wider than the T3 opening by a descent margin. I'll post pics tomorrow...then you can decide.

 

Kewl,

Do you think that causes backpressure.

Or could it be ported out?

 

Well, I have a head porting background, so I port everything just cause I like to...

All turbo setups and mani's have some form of "backpressure" versus the intake pressure. Shorty runner mani's just aren't ideal, they are made more for packaging and cost.

I've worked the flange to assist the exhaust flow in making the turn. I'll post those pics as soon as I can.

 

Great thanx

Im working on a new type of Manifold for the s2000 and this seems like it would be better than a log and not as complicated as the three tubular type out there.

 

The manifold looks good, would like to see how it matches up inside that flange. As for the mini ram, we build ours differently, and this provides great oil line clearance. Just a thought, if you want to go back to the old mini ram design. We have seen others that place the turbo super low, so we did do something different with the collector and runners.

 

Yeah, you have great clearance there, no doubt....that's a good job. I guess the other compromise with the mini rams though is that cut down collector. I know there are theories on how these side by side collectors flow versus a standard radial design, but noone addresses from the armchair how flow is affected by chopping a radial down either.

That's great clearance on that mini ram though...outstanding. That's about the height my jig is set to, and like i said I'm gonna build a mini just to get a feel for it. We'll see.

The idea making this mani was kind of because of the same situation like Onefstek has. I had this collector sitting around for a while, and wanted to use it somehow. This guy wanted something different so ta-da...something different. I can't say I fully intend to produce more of them, I guess I just wanted to get a feel for what people thought of it. If someone really wanted one I suppose I'd make it, but to be honest it's a bit of work as far as inside welding complexity goes.

 

I like it, its a pretty straight forward design. If I had someone that could make me the collectors, I would think about making them and dynoing them up against some of the other designes we make.

 

Yeah, that was my hope. If I make a miniram on the same jig I know this guy will be all for a dyno comparison. He works for a shop locally and the owner made all the cars for 2Fast 2Furious, and is apparently slated to make the cars for the fourth movie (god help us). So he has connections and such.

 

is that the name of the 4th movie

That made me chuckle pretty good.

 

what about welding a little kickout on the pan to extend it out to the turbo to aid in oil draining?

 

It's not really necessary. A simple 45 off the turbo provides enough drain and the height is adequate to accomodate the fitting and line.
