based loosly on gtt 230+ spec but with milly catback on 05 facelift mcs

Mine and Alski's specs are very similar...

17% Alta V2 Pulley
Alta CAI (with stock pipe)
GRS intercooler
JCW 380cc Injectors
NGK iridium Spark Plugs
Optimised Bypass Valve
Play MINI Cat Back.

...but I'd sure as hell like some more torque:

Peak power = 238.3 bhp @ 7127rpm
Peak torque = 178.1 lbft @ 6646rpm

2154rpm: 134lbft
2500rpm: 142lbft
3000rpm: 150lbft
3500rpm: 158lbft
4000rpm: 165lbft
4500rpm: 168lbft
5000rpm: 169lbft
5500rpm: 173lbft
6000rpm: 175bft
6500rpm: 178lbft
7000rpm: 177lbft

Said this before but my cars peak torque makes it almost a VTEC

It amazes me how much difference there is between our cars with similar mods; I can't believe the manifold makes so much difference - I appreciate all cars are different

2076 rpm = 150
3500 rpm = 180
4000 rpm = 188
4500 rpm = 190
5000 rpm = 188
5500 rpm = 185
6000 rpm = 185
6500 rpm = 175
7000 rpm = 170

Peak: 191.2 @ 4638 rpm

Defo need a manifold if it improves torque lower down...

...coilovers first though

actually the exhaust manifolds can be made to alter the peak wherever you want them


ours is made for track conditions, you have roughly the same torque curve as a well designed header down low but mid to up top our header is much better. Overlay some of our graphs on other cars and you will see the difference. Remember all our numbers are WHP numbers so if you want to compare yours with ours add 12-15% to our numbers to get your bhp

I think I read your post right, by header I assume you mean manifold as opposed to a cylinder head. I think Cylinder head is way out of my price range for engine mods.

If your talking manifold have to admit I love the look of your full system posted in your forum, as really like the idea of the cat being moved further down. Concerned about the noise though, don't want my ears to bleed LOL.

Not getting any one soon though and I'm sure when 1320 get one will be able to compare it against graham's full miltek system which I woudl of been happy with

Ideally I want torque in the 200lbft figures, not to fussed about the power so long as its no lower than 230 (what i'd aimed to get it to before realising I aleady had it LOL )

[Razorlite]

Thanks to everyone who has participated so far, very interesting to see the comparison between Damo & Rigsey too with difference in torque.

RMW - just out of interest are there are any preferred tuners in the UK who actively import and use your parts that form their performance packages?

Cheers,

Mark

ps Keep sending the stats - its very interesting seeing whats on offer out there!

Hi guys

Please can I add the following that may clarify the power/torque debate:


Power [kW] = (2 * pi * (engine speed [rpm]/60) * Torque [Nm])/1000

As you can see, engine power increases in proportion with engine speed and torque. So, it is very desirable to tune the fattest torque curve you can across the whole engine speed range in order to satisfy mid-range driveability and peak power requirements. It can be said that Power is, in effect, the rate of change of work done [i.e. torque] from the above equation.

A tuners aim is to maximise the engine torque at peak engine speed by maximising the airflow through the engine and achieving the largest (safe) cylinder pressure the combustion system can withstand.

So, in answer to your question "is torque more important than bhp?", torque is power therefore is equally important and relevant.

Cheers

1320 autos are the people you need to speak to

In the USA we call an exhaust manifold a header and the cylinder head a "head"
We have spent considerable time and money making an exhaust which works unfortunately it isn't quiet like stock

[Damo]

Well I currently have a Play MINI that is a lot louder than stock, and I've got used to it at speed on the motorway, but if I was to get anything to loud on the motorway my Mrs would kill me

The full miltek system is louder than mine under power but sounds quieter than mine when cruising. But then Graham's car is geared higher as mine is a facelift his isn't.

to fool the Mrs... slightly crack both windows... it's amazing how much quieter it is
