View Full Version : Reversing the Inlet

I know there has been some discussion about this before and most people think it is pointless but has anyone actually had the car running with normal inlet and reversed it and therefore has info on effects on lag, throttle response, power, torque etc..

I assume it will just improve spool and less lag etc.. but wondering if it is enough to go to the trouble.

Well it does look a lot neater and in the ideal world it should be done..

but just wondering if I would actually notice any different on a road car??

I am hoping to do anyway but not sure if I am wasting my time.

I know that Pat, Mark and I have all run with a reversed manifolds. Personally, I believe it is worth the effort and the loss of aircon.

What happened there???

You posted second.. I replied and my reply slotted infront of your post???

Also I have two notifies but only one post from you.. confused..

You been hitting the delete button rather than reply.. http://bbs.22b.com/ubb/smile.gif

LOL

You do.. so one vote for reversal..

I think aircon is going anyway..

used it twice this year.. once because I hadn't used it and wanted to check it still worked and another time when travelling between wedding and reception in an ushurs outfit.. next time I'll just have to sweat it out..

All that extra weight must cost me in petrol consumption..

I was thinking about this today for the new car... Custom Rad and IC so that the ports on the IC can come over the rad, Turbo outlet under the inlet manifold into the left port and then out of the IC into the Inlet.

Rob.

Wallis also has Reversed Manifold..

Tweenierob,

"Wallis also has Reversed Manifold.."

Technically, that isn't the case. The manifold isn't reversed, it's been modified to mount the a throttle body on the front. http://bbs.22b.com/ubb/tongue.gif http://bbs.22b.com/ubb/wink.gif http://bbs.22b.com/ubb/smile.gif I had remembered his front mounted throttle body arrangement though... but I wasn't sure exactly how long the car has actually been running on the road that way. http://bbs.22b.com/ubb/smile.gif

Indeed but I think you will find that cutting
the throttle body off the back and remounting
on the front is the only way you can reverse
the inlet manifold as unfortunatly unbolting
it and turning it around will show that it
doesn't actually fit..

As to Davids car running like it..
it was running like this in it's previous
incarnation with Davids FMIC with a standard
throttle body repositioned.
In that set up it ran on the road and was
dyno'd etc IIRC of course and was running
perfectly.
The new incarnation has a different inlet but
again throttle body on the front but with a
massive throttle body as shown in Davids
latest thread on SN.

I was just interested to know if anyone had
done a before and after comparison on the
road.. which it would appear not..

Looking like I might have to then

Hum...

Didn't you see my first post? I was only under the impression that you can reverse the manifold because mine was reversed... but now you mention it, I don't really have anything other than that to base my wild flights of fancy on! http://bbs.22b.com/ubb/rolleyes.gif http://bbs.22b.com/ubb/wink.gif http://bbs.22b.com/ubb/smile.gif

I am sorry Moray, after I typed thaty I then thought.. "Hold on a Minute Moray said he has ihs reversed" and it was you
refering to Davids as a throttle body move..

So does it just unbolt and turn around then?

Confused now..

The '97 version manifold will reverse. You need a silicon hose with a bend in it to clear the bonnet. I don't think the earlier manifold is much different in this respect, but I can't say 100%. I have looked at the two manifolds alongside each other, and I can't see there being a major issue.

If you are running thermal spacers between the manifold and the engine you may get more problems with bonnet fouling.

PS: If you run an inlet duct under the manifold you _may_ need to look at removing some of the under manifold castings, if there are any in the way. I mean there may be some bolt points on the underside of the manifold (fuel rail mounts etc) that need to be removed. It would be a good time to go parallel fuel feed to. http://bbs.22b.com/ubb/smile.gif

It might be the phase 1 that won't then.. or the addition of the spacers..
Interesting though..

So did you drive with it the normal way and then turn it
around? can you give a comparsion of before and after?

'cos from a power point of view, there seems no need..
I just thinking drivability wise on the road..

Sounds like it is best I run it the normal way for ease
to start with and switch it later...

Soubnds like it would be difficult to compare benefits too
as likely to change lots of other stuff when reversing it..
like parrellal feed etc..

phase 1 will not reverse.. see diy fmic thread..

Thought there was a reason and was sure it was you that had found it David...

Come on David reply to my email, how much do you want for your old inlet already sorted?
