Will do... Going from 3.23 to 3.64 gives 14% more torque at the wheels. Production ratios are designed for a comfortable cruise on the motorway and optimal mpg. With a revised ratio the revs just fly up the range, helps the car get into the power band quicker when exiting slower corners etc.

M@r said:{"]Insurance not a problem. Remember I had an Elise that went from having a K Series 120bhp na engine to a Audi 20v Turbo putting out 250bhp! Insurance was not a problem. I've also got an RX7 that has almost doubled its bhp by heavily modified internals, one large turbo, additional injectors etc etc etc. Again no problem.
Benefits of being 38yrs old, no convictions and living in the lowest risk area possible
Removing and putting back to standard if I want to sell is expected so not worried about that
I've spent quite a bit of time talking with insurance companies about fitting a supercharger. The problem is not the cost of a policy but that no company I've found would offer me cover of any kind with one fitted.
M@r]{, if you can find a company that will offer insurance please pm the details to me as I've been seriously considering going down this road for a while as Beedub knows...
Group buy anyone?

Im thinking 540hp with weightloss. Perfect.... The car probably is at its best a 400 hp however.... Its just doesnt need 500 plus hp.... But i wanted it sooo.....

How does the forced induction change the power delivery? One of the great things about the s54 is the power curve, its so linear, and peak is right on the red, just where it should be - not 1500 rpm earlier like all these newer forced induction lumps that are all midrange and no fizz.
With weight loss the problem is fundamental - it needs to lose weight in the nose to improve turn in and reduce inertia up front.... problem is, all that weght is the engine isnt it? You'd have to shed weight at the back, and then start moving stuff in the front to the back (eg washer fluid reservoir into the boot )..... but i'm not sure its possible to drop 50+kg from the nose
Love your car though, it always makes me feel guilty about using mine as a daily hack!

well the way the centri builds boost is completely linear, no throttle lag, no instant boost, you have to rev it to make power so basically is feels like a 550hp n/A s54, or like a big motor engine swap, no lag, no messing, now heres some figures that we used to calculate the meth gains, LOOK AT the curve!!!!!! LOL its insane!!!
These vortech blowers with some boost through them really start to come alive, capable of 775hp... im just tickling its belly....
this is from a usa car on 93 octane....... this particular car had 85k miles on it at the time!!!! This is a Stage 2 + dyno with METH ON!! thats 485 WHEEL horsepower!!! that well over 550hp crank!!! but just look at the curve..... just like stock just higher up the chart!!! supercharging the s54 takes away NONE of the s54 character, infact it enhances it and leave all the m-power charm in place.
ESS VT2-550 (93 octane)
AEM Meth Kit 52% water/48% Meth
ESS Tuning VT2-550
Specs:
Boost pressure: 9 PSI
Horsepower: 550 SAE/507 DIN (65% increase over stock)
Torque: 350 lb-ft
ESS Rated to the wheels: (15% drivetrain loss)
HP: 550 SAE x .85 = ~467.50
TQ: 350 SAE x .85 = ~297.50
We put down to the wheel on a low reading dynojet (E92M3 put down 306whp)
HP: 463.62
TQ: 307.94
The whp numbers are even better than what the kit is rated at... check out the torque!!! Ignore the the A/F reading on the baseline dyno, the sniffer backed out of the exhaust.
After fine tuning the meth settings on the dyno... (again these numbers are to the wheels with 93 octane + meth) An average of 22-25whp gain across the board!!!
HP: 485.65!!!!
TQ: 323.18!!!!
pilchard..... check out that peak number.... no mid range HIT just smooth building power!!! MUCH better than a turbo curve... the more i rev the more the power comes, no flats, no dips, no bucks, just clean power....
with our better fuel here and my mix of 110 i think i can safely put down 500 WHEEL horsepower...... will be back at simpsons shortly for the big dyno runs and to dial in the meth/water injection.....
but god... everytime i look at that curve i laugh...... awesome

after taking out the stock items you loose a hell of a lot of brackets ect ect the ess kit uses all lightweight materials where possible, ive dropped a good chunk of weight from this car, im certain the weight implications are negliable.... hell ive cant tell its up front.... like i say.... 2 gear @ 40mph.. bone dry foot down..... if i look in the mirror all i can see is 2 long black lines.....
moral of the story. mark..... you will not regret this decision if you go their.....
I would be interested to know the best place to insure a car with a supercharger too so please post any tips.
It's not the cost of doing it or the selling on that puts me off, but for a car I don't do many miles on, I would feel very ripped off paying a yearly huge bill! I'm 51 with max years NCB.

That power curve is spectacular!
I've been thinking of chopping mine in for a 911, but having clayed/polished/waxed it its looking lovely again..... and the sun was out last week..... i dont think i can part with it
Supercharging my daily driver....... whats the impact on mpg!?
The wife would kill me

the MOST ive managed was 25mpg on a run to simpson.... 6th gear with 1psi of boost showing @ 75-80mph...... if you dont use any power i reckon you could manage 20-23.... but the power is soooo addictive....
The car is a mad man machine..... just for reference a 458 italia runs 430rwhp...... so were making around 60rwhp MORE than an italia on this spec kit with the meth on..... thats insane!!!!

When i finally sell this thing..... its going to need to be something very special to fill its shoes.... probably a car i cant afford.....

I don't think insurance is an issue I've spoken to my insurer and from what I can remember the incremental cost was less the 20% of my current premium. My biggest concern with s/c is that im yet to see one that's used heavily both on Road and track. I mean the s54 in stock form does we temps go over 100decs after 7-10 laps of say Bedford, I'm not sure what charging would do to these temps...
I too am very closely watching this development and as soon as the above concerns are addressed then it's game on for me too!!!! Albeit just the 440hp option...

ive ran this thing all day long in 27 deg C heat @ curb/ and the car ran like stock.... cooler with the large front mount oil cooler (adds another litre of oil), remember the supercharge is completely independant of the oil and water systems that lube and cool the motor, it has its own completely independant internal oil supply..... Aits are cooler, oil temps are cooler??? dont worry about temps with this setup, one of the one track used cars in the usa and to add in TEXAS, hot as f**k runs the 440 setup in track days and has done for nearly 2 years, reliability just isnt something thats a worry with this setup...
give me your insurance companies number please..... sounds too good to be true.... id like to switch to them for sure...
