Quickest 4 door?

The BMW M5 showed its worth in the Territory last month, but for sheer grunt, how about a delimited S65? It's my new favourite 4 door - for this week at least.

Whys that mhh? Have you just driven one have you?

 

Nah, I just like the look of the 1000Nm of torque.

 

I almost fell off my chair!! WOW!

 

house moving torque............

 

When I first saw the topic I thought of the Audi A8 W12 or S8 but then just went to the merc site and saw all the figures. Holy ****!! That would fly.

 

UGLY HEAP OF SEVEN CLONE.

 

yep. i'd move out of my house to live in it.

 

typical benz.......................S class with bling bling.


and what depreciates more rapidly.............a volvo, a jaguar

as stated once before......A benz is only popular in the subdivisions or for visiting someone in a trailer park

 

i take it this isn't the E55 replacement ?

sorry , don't know much about MB

 

Correct.

 

I had a ride in a S65(prev shape)....only one word....grunt! Pity the new one is ugly.

 

Jon, you were right about the sparkplugs, changed them today and the car runs sweeter than I can remember, even seems to have more grunt down low

the car used 4 litres in 6k kms over the last 10 days and returned about 28mpg

another thing I do is put in injector cleaner every 4th tankful and it runs smooth as silk

oh yeah, this car is much easier to change the plugs than the gt4

 

What plugs did you use JM and what injector cleaner do you use mate? Im just curious.

 

ngk bp6es

wynns spitfire

 

Strictly speaking, the correct plug for 308QV is (platinum tipped) BP7EV... but you can't get then anymore and the superceded model has a resisitor in it... BPR7EIX... and is also Iridium and about $20 each...

BUT.... The resistor weakens the spark too much, and the (some) modern fuels are so bad they tend to foul plugs... so BP6ES is a good hotter non resisted option, but for exactly the same price ($3 each), BP6EY is better... as it has a v grooved electrode which keeps a better spark for longer.

 

they were out of 6ey and I change my plugs at the 5k mark the same as the oil and filter

 

yeah i've used some of those, BP6ES or whatever is in my *ahem* f-car now

do you subscribe to any of the voodoo plugs getting around? eg these http://www.brisksparkplugs.com.au/ or any others getting around lately?

 

NGK plugs are the best.
Have you ever heard of Chemtech? That is a really really good injector cleaner. I have used since it was recommended by Tafe teacher in 2000. Give it a try next time. Its in a little blue bottle, costs around $13.

 

Nope. I subscribe to the KISS technique...

Keep
It
Simple...
Stupid.

I have a locally developed spark plug tester... really cool gadget... just drop the plug in, push a button and it sparks up in front of you... Really useful tool which saves heaps of time and messing about. Also proven to be invaluable for racing...especially karts/bikes and low power stuff where plug type/gap/condition/operation can make large % difference to BHP.....

Worthwhile chasing optimum plug set up in powerful engines too... if you take things seriously enough to worry about 2-3 BHP.

 

For $500k u want it to be quick I like it but its no commodore beater hahaha.

 

of course! 2-3bhp in my POS (900kg) is sphincteromically like 10bhp in a 'normal' car (1500kg)

 

Hey who do you think you are, trying to get this thread back on topic

 

Fastest four door sedan?

Bentley Flying Spur

195MPH
0-60MPH 4.9sec

The 0-60 time suffers a bit form the 2475kg kerb weight!!

 

Sams tester is a neat little trick but it doesn't take cylinder pressure into account so it doesn't quite give you the whole picture. The test rig they've got at EFI Tech for benching CDI and other ignition setups includs a chamber that can be pressurised to 160BAR with a camera built in for viewing. Even 160BAR isn't enough but it's amazing the difference a bit of huffin' and puffin' makes.
