You have completely missed the point.....
445ps (=438.90 hp), MRC .........The car was Dyno'd again with DMS, and confirmed 440hp (=446ps) with MRC map.
After which point I had the spacers fitted and the Kit and then a remap. Nothing else changed, not tyre pressures not wheels nothing just those three things

OK Sorry - I thought just a map made the difference so you are saying spacers, induction kit & a remap added 30 bhp which is a great result

Re:heavier wheels - makes a huge difference. The only reason f1 cars are fitted with carbon brakes is that the unsprung mass is much lighter which adds acceleration and braking performance.

I don't doubt the make a huge difference (I used to have a production racer & you couldn't change the wheels) & my current bike has forged Marchesinis - if you thought unsprung mass was important on a car, try a bike when you have to tip the spinning wheels over ! Yes the acceleration, certainly the handling & stopping are all helped by a lighter tyre/wheel combination but surely they can't affect the bhp the motor produces ?

It won't affect the engine output but it will affect what the dyno sees.

The dyno is calculating the bhp from how fast the car accelerates a known mass.
So if the wheels take more energy to spin up then it will affect this reading.
Likewise the coastdown calculation will be a little off - hard to say if they would exactly cancel it out.

Do you think upgrading to Carbon brakes disks would help handling and acceleration? ... On track days I switch back to my 19" wheels, as I use Michelin Cups

[adsgreen]

Yes.
Brake fade issues aside the main reason f1 use it is purely down to performance of being lighter.

But the question is would you notice it... Hard to say but Every kg saved in unsprung mass (ESP rotating unsprung mass) is the same as removing (rule of thumb here) 10kgs from the vehicle.
Don't have the weight figures between the ceramic and steel brakes though.

Is it worth the 6k+ to fit? If you track very regularly then The increased lifespan and durability will be beneficial but in terms of outright performance... Difficult.

Any more pictures and details of this kit you have installed yet?

If the kits good kiwi,i dont mind taking that old gruppe M thing off you cheap if its helps

You are first on my list if I sell it Jules!

Pretty sure I woudl modify the 'Renich' kit to run with the GruppeM as the sound is addictive

The ratio I was told was 350:1 so unsprung mass is very important, although that doesn't nexessarily mean ceramics as some light 18s with track tyres on would probably save more weight in the right place as well as provide more grip. I have never used ceramic brakes so can't consider the braking performance benefits but in terms of unsprung mass I would have thought your money could be better spent elsewhere. Infact when production racing bikes you had to keep the std wheels & brakes so by stripping as much weight as possible off the sprung mass the handling actually got a bit worse...

I have the GruppeM version on my car, in other words, they make two types of Kit one for the OE box and one for after market. it points straight at the Cone filter of the gruppeM. This means that you keep the sound as well as feeding the GruppeM with accelerated cold air...I wonder if this also has a scavanging effect on the air around it. And the effects on the temperature of the inlet manifold are profound and oil temps are still reading at 95-96 at 80mph on the motor way. I'm going to try and go to another dyno, this week to calm the sceptics... It seems to be the only way to get others to eat their words and accept that the power can be achieved using a different method.

Where do we find details of this kit???

I think there are loads of people here who want to know. As a GruppeM owner I know I do, I am under no illusions as to how much power we lose with heat soak

Any details yet?

EDIT: I am not phased about the cooler just the carbon CAF

[P_G]

I'm still interested in pics and details on the race spec. aux. rad. single for double replacement if you could oblige RTS BRAT?

[thedoluk]

I emailed Renich askng about info on the kit but not had a reply.
