931 vented badge panel/nose on a 951..!

This airflow interruption discussion had been proved nothing more than hear say. You can see from this pic below, the 951 panel beside a 931 panel. Note the extra structure on the 951 panel that will block/seal off the vents added from the 931 panel. The vents will serve no function other than looks.
(that is speaking for a 951, not a 944S.. though I suspect they will be similar)

I have had the same idea, I have a 944S that I have dropped a turbo Engine into and a big intercooler and decide to fit a vented nose panel. I still have a bit of work to do but here is a picture of it mocked up on car
Looks great.. You could just block them off like the above.. then there will be no chance of any impact on performance.
For an intercooler to work well, don't you need cold air pushed at high volume and under pressure?
I own a 1986 NA car which was turbo charged with a standard intercooler. When I bought it, there was only a vented badge panel feeding the intercooler. On track, the car lost power lap after lap. This was cured with a turbo front end.
This May or may not have relevance to your build but thought I'd pass on the experience all the same.
For interest I have just had the ends of the intercooler altered as many do and, for appearances sakes, had the vented badge panel re-fitted. I don't think it will affect anything negatively (I guess I will find out) but I do wonder if it might increase under bonnet pressure at high speed which is making me consider bonnet pins. Yet to get the car back so cannot yet comment on the changes.
Cheers

Maybe.. But you cannot argue with the above pics. If there were vents in the 951 panel with the rear structure still in place, I cannot see how airflow would be interupted. Also, I don't care either, cause I'm arrogant and I'm doing this job whether an anorak likes it or not, it's my car and I like the look of the vented panel.[

If Jon Mitchell would like to offer his insite to this argument I would be happy to listen, but I don't see him in this thread over the last three pages, nor would anything he said have any impact on my descision to continue with this modification.

Jon tends to post on Tipec more than here.
He did do some work on airflow and 944 turbo badge panels if they were there for anything other than show (ie not blocked off) and iirc he did find that the 924 turbo vents produced worse airflow than no vents. There was a preferred design he came up with that he felt helped which I believe were 2 horizontal slots about 6" in length.
I rather like the 924 vents and have toyed with it for a while but its not exactly vital. I have a bonnet scoop from a long dead 924 turbo so that may go on too.
If they are blocked behind then as ornament they are entirely personal choice. If someone made a bolt on panel with vents I'd probably buy one but with no intention of improving anything.

Please your good self (or Jon) explain to me in great detail, exactly how 931 vents fitted in my 951 panel pictured below (albeit with some (crudely applied) filler seal in blue I did in paintshop on the pc) as an example of
the finished article,) is going to have any impact WHATSOEVER in the turbulence or otherwise hindrance of the performance of my car????????
Aside the minimal effect of aerodynamics in tiny fractions beyond giving a damn about outside of Formula 1 Racing, I think you will struggle.

So it's hear say then. I said that many posts ago, it's all hear say. Missinformed information passed from forum to forum, more ignorance and miss understanding added along the way. [8|]
I bet none of these naysayers had even seen the two panels side by side like in my picture above. ... But wait- John Smith on forum X thought its not right, Jim Jones read that and posted on forum Y that Someone said it was no good. Next thing, add a few years and forums and more ignorance and pretty soon, it's Gospel.
I would advise things like this read online taken with of pinch of salt.
Arrogant? It's this sort of "rubbish" that may make me appear to be. If you have no facts experience or knowledge of the given subject to back up your statements, then just keep out of it. And another thing, if you have nothing positive or constructive to contribute to a topic, then no one wants to hear it. [X(]
EDIT: my post is not aimed at you GPF.. Or any other constructive posters within my threads.

Hi All,
Well to me it seems that those of us that are putting vents in are not doing it as a "performance enhancement" but more as a "visual enhancement" [
Gavin
Exactly.
QUOTE THE 2ND SENTENCE FROM MY OPENING POST..
Sure, I appreciate it's not for everybody and it is arguable that it improves or hinders performance.. I am not bothered about that, I m doing this purely for aesthetics. If I find there is any negative impact on performance then I can blank the vents off from the rear if need be.
If only some would only get upto speed on the thread as a whole, maybe some disagreements could be avoided.

Can I throw something into the equation ?
Lindsey Racing doing a modified badge panel http://www.lindseyracing.com/LR/Parts/944S5HEADER.html now I know this is for their Stage V intercooler set up but surely they wouldnt provide this if it didn't significantly improve the airflow ?
