Yes and nothing wrong with it,

There are people on here in gen 2 cars pushing 365bhp+
Nice effort at diversion, though ultimately futile.... The only people who care about dyno numbers are people with dynos and people with numbers that are too small.

Sadly its simply the memory of your bright appearance onto the forum and a moment that remains still your finest. A high water mark of D-baggery.

You live and think what ever makes you feel good, I back up every thing inc my own brake tests I did the other week.
I had vbox results from my last car and now I have vbox brake test from 3 set up in my gen 2 cars,
Sadly for you , you have been wrong every time, but as I have said, you live in that thought where you seem to think you are right and even with proof you will say black is white, so I cannot argue a point once the data has been posted.

Have a nice weekend in la la land. :-)

Can we try to keep away from the arguing please lads, I didn't intend to start any arguements.

I'm not really one to hang my hopes on dyno figures, and tbh usually I'm not really interested in the peak power figure they give. I'm more interested in how smooth the power/torque curve.
40bhp difference just seemed a huge difference, hence my original question.

Forget the figure of 40bhp, let me try re-word it.
Is a uprated exhaust likely to give a large increase in power on my current set up?

Has anybody dynoed my set up with a oem exhaust then replaced it for a uprated one and seen the dyno difference?

The rear cats kill the power, end off, the gen 1 base map also has that Awefull dead spot.

Even if you got no Bhp gain, removing the dead spot improves the driving experience by miles.

Just doing the rear exhaust section alone gives great gains on the gen 1 cars and smooths the graph out.

Must be 50 or 60 people with the mods I did all with back up dyno plots, it is all there in black and white.
I set out to prove the USA claims to be bull st, so did all the mods, went to a dyno where no one knew me or my car, went back modded up did another dyno ,
Alass I set out to disprove the USA claims and ended up confirming them :-)

We now have gen 2 cars with the same mods and proper bespoke maps running 365bhp

All possible, but on the gen 2 all 4 cats are in the manafold so.A lot more expensive to buy a manafold and full exhaust system.

Fit the rear section ,enjoys the gains, and don,t post as people here will just not believe you .:-)
I don't post anything I do to my cars here anymore, not worth it.

Still not one drop of remorse huh Nigel. Not for all that happened then, not for the waves still crashing even now. Incredible.

Its amazing how strong my fantasies can be at times. I even imagined getting emails in my inbox.

Heres a play I am working on at the moment. I figured I should channel my imagination into something useful.

Act1.
The main players are introduced for the first time.
1: Hey, thats amazing what you have done with your car. How did you solve the cable throttle onto an e-gas car problem?
2. It was easy!
1.Really? its almost the largest problem going at the moment. What you have done is quite simply huge. Can you not share?
2. Im not telling you how I did it!
1.Ok. If its proprietary or you just don't know thats ok. If a shop did the work can you tell me who it was, I would like to ask them about it if you don't mind.
2. Look. F&^k Off

Act2.
An image is posted. Its a regular street throttle body.
1. Ah, its just a GT3 throttle body. Thats a shame but it makes sense.
2. No, its a Cup throttle body
1. Here is a picture of an actual Cup throttle body, from my Cup engine. See how different it is. It is cable operated and has no plenum. The Cups don't use a plenum.
2. I am ignoring you, but still telling everyone interested that they need Cup TBs. There are many interested since my dyno number is so big. (this part done as a sort of mime montage to music)
1. Here are details on the Cup throttle body. These things are expensive (£2000 +). Have a look on your price list for the mods incase you have been over charged. A street throttle body is around £200. If you need help or more info in getting money back if you have been overcharged let me know. Hopefully its just a miscommunication.
2. I know how much I have been charged and my invoices are always fine. Its all none of your business. F^&k Off.

Act3.
The travelling circus takes to the world in a non stop tour that will continue longer than mousetrap has played in London.
2. Roll up, roll up. Marvel at my amazing HP figures. Yours for only a Cup TB. Its the crucial part of the puzzle. Those motorsport boys know their stuff.
1. Hey, you shouldn't be telling people to buy a Cup TB when you know thats not what you have and also that it will not fit. Its expensive and cannot be returned when ordered. You are going to cost people lots of money! Just tell them what you are actually using. It doesn't diminish your efforts in any way.
2. F&^k Off.

Act 4.
This is act is played out by several silent players running around. I envisage it being structured like a piece of modern dance. Minimal Lighting. Just the sound of feet on floor.
The players spend many many months, even years, running defence on this situation. Emailing people in any thread where the PT Barnum-esque Character 2 suggests that they should get a Cup throttle body in order to prevent them making an expensive mistake. A £2000+ mistake. The circus seems so plausible, after all its been tried, tested and results posted.

Act 5.
As everyone is leaving, they think its finally over....
1. Its back, its back. The dyno is back!!!!

Lights out.

This play is a completely fictional. Any resemblance to characters, living or dead, or to events is purely coincidental.

Ask Mr Demon what his before and after exhaust figures were?
The only difference between your car setup and the one in that second dyno is:
Softronic vs Your own map
OEM plastic plenum vs IPD plenum
Exhaust.

FWIW, I at one time had a 4 litre race spec M96 engine. It made almost 400hp. Running cat-less and with custom made silencers made little change to the peak power figures. Running a custom made intake box (with much larger filter area fitted straight onto the bigger TB) did change output by about 8hp from memory. I sadly didn't have time to investigate the source of this change. I would have measured pressure differential either side of the filters to understand if anything was changing from one to the other.

Over on another planet, a somewhat confusing thread where the conclusion seems to be small peak HP gain but higher torque lower down with plenum and throttle body upgrade + headers.

http://www.planet-9.com/981-cayman-boxster-modific...

Pages 5 & 6 might be more relevant.

He is on some thing lol

I was told it was a cup throttle body, I posed a pic and asked a question it was a standard 996gt3 throttle body.
we got though that one years ago, does not change the Bhp figures. Or the many tried and tested results with the same combo.

So bar that slight mistake thinking it was a cup TB when if fact is was just a 996gt3 TB what's your issue ?

Every thing else still stands.

where is my oem plastic plemum . ?



the gen 1 cars are def restricted with air flow which limits the bhp the gen 2 cars have a larger intake.
nothing more to say on the matter. those are the facts based on 50+ dyno results . the word CUP has been removed if any one else finds my old sheet :-)


great little car my gen 1 back in the day.

Did you ever get the exhaust fitted and see results as the thread turned into a slagging match just for anyone interested here are my results softronic ,gt3 throttle body , porsche genuine plenum upgrade all done as a package in one hit . Maybe an exhaust is a must with this set up or you can't get that much power with these mods , or the dyno is wrong

That's a valid point and I think one of the issues with these caymans is they are so good all round that once you get used to them they do feel a little flat and held back and I thought that these cheap simple mods would release a lot of power but was wrong to believe that as NA cars generally don't gain anything . Midrange is better and that's where these cars are really flat so it's fine . On the road great to drive just wanted more power as the thought of being left for dust by a modern hot hatch like a megane is a little embarrassing . The cayman makes me happy and that's the main thing just a 350 hp cayman would make me happier

You were not wrong, you did not change out the most important thing !!!
change the exhaust ffs, don't post dyno's of 1/2 the mods when the mods NEED the rear cats removed.

If you want more power did you get your name down on the GT4 ? the rumor mill is ni on 375BHp on all the forums and leaks.

I will do the exhaust and see what happens I hope that makes a difference either way it's not the end of the world . I guess the answer I was looking for was that the exhaust could make a fair bit of difference . Not heard of the gt4 but sounds pretty exciting will have a look .
