Agreed, different delivery with the same level of peak boost.
the SC will incrementally have more boost in almost direct relation to RPM, so therefore making peak boost at peak RPM. Flow and therefore torque can be controlled to smooth out the delivery for the road kits
the turbo will give...
LAMBDA is critiacal to correct running of the engine
with age the sensors do degrade, but a simple diagnostic check will assertain the functionality of the sensor
your correct in the downstream sensor only checks for correct opperation of the CAT, but will of course leave your toxic...
on track is one thing..... and back in the everyday world you may want more power to improve overtaking, or to accelerate faster down the motorway sliproad...
I have said this time and time again.......
if YOU want to go faster then buy engine mods, if you want to be faster round a track...
Hi Guys
We are always looking of ways to improve our service and range
we would like to know what you feel YOU would like to improve or change on your 197
* Engine
* Drivability
* Power
* Handling
* Ride
* Styling
* Seating
* Brakes
Would you...
its based on power...
BSFC.... Brake Specific Fuel Consumption.
its the same engine.... so with more power it will use or need more fuel to reach target AFR
so if ITB's make 200 bhp and cams and headwork make 200bhp it will be like for like fuel wise...
Andy
You wont get less economy with ITB's
but there is a simple equation.... at peak throttle you need more fuel to make more power.... that applies to ANY tuning mod...
but you will typically get about 280-300 miles from a tank with ITB's
Andy
Headwork is good for increasing torque across the range on a standard ish motor.
I wouldnt expect a great deal more peak power wise, but will infact be a fair bit faster.
Andy
in loose terms when the tires are hot, reduce the pressure to about 28 psi
obviously when cold this will be near 22.
I would still use R888's unless really wet
