Bingo--inside radius's for the win. Air has to take way to many turns in this manifold set up--FI or not--doesnt matter.
bse50 has talked about this before and mentioned a different design. It would take some work but a fresh air source could be done for a passenger side intake-- just swap the battery to the drivers side.
the best example i have seen....http://horsepowercalculators.net/wp-...ld-Design3.jpg
of course this one would have to be adapted for us--but the advanced features are there. This design deals with surface air tension and the unequal air availability of the standard log type.

 

Strut bar is not really needed and the battery can be relocated.

 

The strut bar is not really needed in autoX but for track use my p-box tells otherwise
If it's not the strut bar is the alternator in that case, that's why I used a different approach when doing my tests since I already have a smaller battery that doesn't get in the way

 

the alternator can be side swapped also--wouldnt be much of a problem actually

 

Surprised nobody posted this yet. Looks like Mazdatrix is working on one. Can't say I'm a fan of doing it this particular way. It's frustrating to watch other people klutz around when it seems so obvious to me ...

 

Sure, as long as you don't mind losing your A/C compressor to make a new home for it

 

Its cuz they cheated, they just took a petit supercharger kits uim and replaced the supercharger with a hoky throttle body.

 

Interesting. I was just on their site and did not see a picture of it.

 

Doesn't aluminum manifolds heat soak faster ?

 

^yes

 

I doubt you would loose the air con. I run a 6 rib belt between it with no dramas.

 

Most side mounts are usually located where the AC compressor is. Unless you're planning to cut a big hole in the subframe I can't see where else you plan to mount other than the usual side mount location.

 

well if your relocating the alternator to fit a custom intake down that side... your removing the std upper-intake manifold and there is a nice spot left for the alternator where the std throttle once was. just flip it let to right on the same engine mount.

may need to move the coils but not a big problem.

 

Yes, it makes complete sense to make compromises for an already poorly thought out idea

 

lol typical. at least your consistent.

 

If you are referring to my unwavering dedication to function, common sense, and real world results then yes you are correct

 

depends on what your trying to achieve. there is so much room in the rx8 engine bay you are very unrestricted in what you can do.

why don't we all follow the old school method and replace the air-con unit with the alternator. makes sense in a race car without the need for air-con, but not much sense in a road car.

if I flipped the alternator and ran a v-mount I'd loose about 50cm from the inlet tract compared to a v-mount with the throttle (or pipe work going back) on the right hand side. it would be difficult to measure the real world results, but it wins in function and common sense.

 

that's exactly what I would do and you can lose a lot more than that if you put your thinking cap on, but again you missed the point that the present location of the alternator is not an issue.

This started with a side mount comment made by someone else. I didn't suggest moving it, somebody else did. I pointed out the issue with doing so. You jumped in, also not aware that a side mount means moving or removing the AC compressor. After having it explained to you, you then suggest an alternate top mount location. Doing so is completely unnecessary unless you just happen to like making work for yourself with no real benefit towards optimizing the system.

What you don't follow is the old school method of common sense. Keep trying to spin it any way you want. The obvious truth is you didn't understand and you still don't.

 

yeah the gain was only a guesstimate. I agree moving the alternator may be unnecessary but I agree with olddragger that relocating the alternator is easy people want to do it.

sorry team you might not have suggested moving the alternator, but you incorrectly assumed that a side swap would loose the air-con.
you jumped in assuming that there is only one location possible for relocating an alternator.

most not all. your the only limitation

you can't?

 

moving the coils and mounting it on the top of the a/c?

 

If you are referring to the alternate top mount position by flipping the alternator to the other side of it's present mounting point, yes that is nothing new. I never said there weren't other mounting positions, just that the side mount position is occupied by the AC compressor and that an alternate top mount position is work with no benefit. Clearly you don't see that, but by all means feel free to waste your effort pursuing it. Keep on spinning whirlybird.

 

I R CONFUSED. Wheres the Manifold?

 

Bump

 

This thread has been around WAY too long for there to not even be a prototype image or rough-estimate pricing available, yet.

What's the hold-up?

 

I would guess there wasn't enough interest.

I've not gone back to read the first post but IIRC this was more of a feeler thread.
I think...
