Ahh the joys of Pistonheads
I didnt want active suspension. Having raced many cars for many years and tries every kind of suspenion I do have a understanding of what works.
Most of applications dont need active and as we can get bespoke builds from Moton and Ohlins to our damper curves there is no need.
I am sure tractive are good but on a road car in the UK a good passive set up with the correct springs will be fine for me

Tractive's active is particularly good for a road 997, one can have extremely soft springing for low speed crappy roads with the damping giving extra assistance and control when needed and multiple damper curves which are selected on the fly, it is revolutionary for road cars hence why they all have some form of it from the factory now.I didnt want active suspension.

Think that's a subjective call.The sort of solution you talk about is certainly in vogue at the moment. But personally, really, really dislike setups with soft springs and increased damping to compensate. For the road, I much prefer firmer springs and just enough damping to control the them. The opposite, in other words. Hence, don't much like PASM and similar active setups. Current have a 9x7 gen 2 car with PASM, and tbh I think it's pretty crap. 9x1 cars are a bit better, but still don't like them.
Personally don't think you need soft springs for a reasonable ride on UK roads. It's damping that causes most of the ride issues, in my view and experience. Not springs.
Which isn't to say that's the 'right' way to go, just that there are alternatives.

Well said sir, a good set of passives will transform it I didnt want active suspension. Having raced many cars for many years and tries every kind of suspenion I do have a understanding of what works.

Hopefully not teaching you to suck eggs :

Ohlins or Nitrons would be my choices.
And please accept my apologies for having briefly derailed your thread earlier on
Hi Jeweller70
Just wanted to chime in and say how stunning your 997 build is… colour choice is perfect. Obviously I’m massively biased, as I’m extremely local to you, running a 996 Turbo (I think 1 in 4 ever made in UK in that exact green colour). Yours looks flawless in the metal though… makes me want to re-spray mine (added to project list!)
By chance did you ever settle on your seat choice? I saw you mentioned Pole Positions as a consideration. I’m sure with your racing exploits you’ve done some seat time in Recaros finest, but if you ever wanted to wiggle into a set of Pole’s, I’ve got a set in one of my 996’s and I’m literally 50ft round the corner mate (how’s that for online stalking taking to new levels!) lol Seriously just message me anytime if it helps you.
Anyhow my friend, genuinely lovely project… keeps my Porsche Project passion alive whilst I’m committed to house refurb and banned from any Stuttgart based thoughts!
Best wishes, Nath

Nath went for Corbeau as I know the MD and don’t want to much bucket for the road.
Pop round you can have a drive....
Hi Marcus, Pop round you can have a drive....
You’re too kind.
I would definitely love to pop round soon for a chin wag and admire the project. Really interested in a few points as they’ve been on my ‘project list’ and it’d be great to get your thoughts on what you’ve achieved.
Speak soon (in person!)
Best wishes, Nath
Initial Dyno reports in after run in.
Fully aware all dynos are different. They key is the difference not the absolute number
We are comparing to a base run an standard low mileage C2S 3.8 (standard 27k miles)
The 3.8 gave 330 hp
Our 3.9 gave 351
Torque is the biggest gain with 30hp more from 3k and 35hp more from 5k.
There is more to come as pre cat lambdas need to be renewed as not reading well.
We feel 370 will be possible and 40hp up in the mid range
Will post the charts when we do final runs.
Fixed ride as well with raising ride height by 15mm

Sorry for the thread hijack....Peter,
What was the power like pre mapping? I am unsure if I am getting the best out of my 3.9 hartech. I have designtek manifolds and switchable exhausts with standard cats I believe. I heard that it might be worth putting 3.8 injectors in. Would like to take it to chipwizards but I am in Surrey and they are in Manchester....
