IPDs - do they work on N/A - let's find out

I bought a lot of stuff from the USA to prove them wrong 4 years ago, as I thought claims were silly big.
I infact managed a 45BHp gain on my Cayman and it was great.
I don't get why UK tuning is so far behind, and people just want to resell stuff and not invest in tuning/testing.
The Cayman and Boxster can release loads of extra power and Torque. Not so sure about the 911's as I have never owned one.
Why no one resold the stuff I used seems crazy as the increase was amazing.
The issue is get more air in you need to get the air out and most new Porsche have 4 cats in the way.
You might get a 5 BHP gain from a IPD on it's own, you might get a 10BHp gain from removing the two rear cats on their own.
but do both and you might get a 25BHp gain over all as they work together to release the power.
AS for dyno you can put them where the sun don't shine imo, nice to get a base result and look at a curve to see where it changes over stock.
But what you want to know is , is it faster and the only way to test that is vbox it doing 3rd gear pulls.
you must have seem my results but all I fitted was a decat rear section, a bigger plenum and the GT3 throttle body, than a remap to tie it all in. but doing just 1 thing would have been not worth it, (bar the rear decat which is always worth it on a Porsche imo)
I could have got even more gains changing the headers/manafolds.
I look forward to your findings, better late than never :-), I am now thinking what I can do to my Porsche Spyder to get 350BHp :-)
which should give it a great BHP/ton figure.
We will be doing vbox as well. The point in this case (and I don't like dynos) is that the difference in vbox times may be small e.g. 0.25 sec, which in our experience can also be put down to better gear shifting etc. We can eliminate the gear shifting to compare the curves but there will need to be a noticeable difference in time. Of course it should support the dyno gains.I infact managed a 45BHp gain on my Cayman and it was great.

The owner of the car already agreed for vbox times.

As I say I look forward to the results
VBox is best done in 1 gear from rolling, hence why i said 3rd gear runs, some thing you can do time after time and get the same results.

This 3rd and 4th gear pulls.
So say 60-100mph in 3rd (if gearing allows) and 80-120mph in 4th.
If a mod has given more power/torque those times will definetely improve.

Hi Gibbo, read your post with real enthusiasm, then read the bit about being for a 997
my C'S was refering to a Cayman s.
It is even better for you! my C'S was refering to a Cayman s. The best modification for the Cayman is the GT3 throttlebody, combine it with the plenum and some high-flow Cats or DE-CAT and on a Gen1 Cayman your looking at a good circa 40BHP improvement and this is proven several times over by actual owners of cars and not manufacturers claims or dyno shops doing dodgy testing.
The 3.4l responds very very well to breathing modifications.
I can tell you its cheap too:-
GT3 Throttlebody from OPC is sub £200
Also if the Cayman can take like a GT3 or X51 plenum you could get that from OPC too and again they are cheap.
As to De-Cat pipes, a decent exhaust fabricator can put you one together for about £200.

delete the rear cats, why do you want 200 cel cats ?
I would be looking at maybe a Fabspeed exhausts. or have a talk to Sharkwerks leading the way in Porsche tuning imo.
I would not go with a UK company unless they had tie ins with these guys for 911 stuff or Softronic for Cayman/Boxster stuff.
ALso some of the USA based race teams resell engine mounts and race ARB's far better than what you can buy in the UK.
I cannot offer any 911 advice as I have never own one, so just talk to some of the USA guys who have tried and tested stuff.

I have to agree, so many UK tuners seem to diss the yanks, but having owned an American car and an EVO X I found I could get better information and pricing from across the pond even after factoring in shipping and taxes.delete the rear cats, why do you want 200 cel cats ?

The UK tuners and shops need to become a lot more mod friendly, infact their is probably a good market in the UK for it, just needs an equivalent to say Fabspeed or AWE here in the UK, as Softronic are happy to work with UK tuners and actually already do, because to put it simply Softronic is the best tuner for Porsches, he is the ECU wizard.

On the Spyder has any tried the GT3 throttlebody, will it fit?
I'd have thought a performance element filter (BMC), GT3 throttlebody and some high-flow 200/100 cel cats would get you around 345-355BHP from your Spyder with a Softronic tune to take advantage of it all.
Scott does a kit for the dfi engine aswell but less info on it., very tempted, But I might just decat the rear with a Remus ti exhaust.On the Spyder has any tried the GT3 throttlebody, will it fit?

2 less cats and a lot less weight must = more Spyder fun. also more warranty friendly just doing a back box change.
still prob net 15 BHp from that though and should smooth out the power, and lose some good weight.

As your not under extended warranty, you can do as you want with the exhaust. 2 less cats and a lot less weight must = more Spyder fun. also more warranty friendly just doing a back box change.

Porsche can't deny you any warranty work for a different exhaust, you'd win everytime in court.
With extended warranty it is simple, put stock back on, get warranty, put remus exhaust on and whenever it visits local OPC make sure your stock system is on.

A GT3 throttle body for sub £200 from OPC sounds too good to be true. Is this a straight bolt on to the 996 3.4l and can I get away with fitting this with no ECU remap? Also if you have the Part number handy that would be useful as I will give Porsche Trier a ring to see what price the throttle body is over here?The best modification for the Cayman is the GT3 throttlebody, combine it with the plenum and some high-flow Cats or DE-CAT and on a Gen1 Cayman your looking at a good circa 40BHP improvement and this is proven several times over by actual owners of cars and not manufacturers claims or dyno shops doing dodgy testing.

I did get excited about fitting a turbo the other week but the cost is outrageous.
So would doing a de-snork make it any better?
Anyone know if a GT3 or X51 plenum fits the Cayman?
What do the high flow cats cost compared to a de-cat?
If you go for a de-cat do you have problems with the emissions in the mot?
Is there an Indy that would carry out all the above mods at a sensible price or is it a true diy case?
996ttalot, is this something you would get involved with? Sorry to have hijacked your thread

Sport Cat pipe = £900-£1200
So big difference in cost.
In UK if a car was designed to have a CAT then it must have a CAT, you won't pass an MOT. Off course you could put car back to stock for MOT time.

I ordered my Softronic remap from a company called VividUK. Since then i've received an email saying the UK operation had closed down and any UK sales would be taken care of by the US parent company VividRacing. Does anybody know why?
Why do they need a UK operation though?Its an electronic map which comes to you via email, no need for a UK operation.
Just speak the US Vivid/Scott direct and they will sort you.

I was looking into one for my 911, but unfortunately its not so straight forward on 911, would need a lot of work to implement at which point it was just not worth it.Other option for 911 is buying X51 throttlebody, intake manifolds etc. which is all affordable until you realise for it all to work and stay within warranty you also need to buy the £3000 carbon airbox, at which point for 10BHP or so is simply not worth it.
Just ring any Porsche OPC, ask for parts, ask for a price for a 997.1 GT3 throttle body, should be circa £177+VAT if memory serves me right. If they are not forthcoming I shall speak to my mate and get the part number.

So there has been much debate on whether fitting an IPD to an NA car will make a difference. I think it is about time someone put it to the test and therefore have brought four parties to the table to resolve this question.
Car 996C4S with no modifications kindly supplied by one of our customers.
68mm IPD supplied by Greg at IPD in the USA - the license holders of the IPD - the original IPD - not a copy - they are supplying this free of charge.
Charlie at SurreyRollingRoad will provide the dyno - on this occasion we will use a dyno in a controlled manner instead of a 60-130 time
We will do the install.
This will take place over the coming weeks and we will update the thread with the results.
No other changes will be made to the car - we will not change throttle body or anything at this stage.
Keep a check on the thread and we will update it as the changes take place.
Ken
This should be an interesting one Ken, Have you done any similar back to back testing on any turbocharged applications? I never managed to log any data after fitting mine, also, intercoolers were fitted at same time which could potentially skew any results...an IPD only mod on a turbo would make for interesting reading.Car 996C4S with no modifications kindly supplied by one of our customers.
