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.....[/quote]

Bdub your insane, your cars insane, And Im jelouse!

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....

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.....

takes me back, i had Bernards old red audi elise a few years ago, very quick and handled well. Built a Rotrex s/c Toyota 20v 1,6 for my track Raw Striker after that, and nothing would get near it. cant beat 520 kilos and 272bhp

[flatout]

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...

i had a R33 skyline GTR hitting 614 bhp..that was very nippy

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...

Yep! I get "What's a supercharger? I'll have to speak with my manager..."
Then a huge wait followed by "Sorry sir, we cannot cover you with one of those"

Let me know how you get on

Have you tried REIS? I'd be very surprised if they don't cover you on this. Bolting a Supercharger to your car is surely less sever than swapping out a 1.8 na K Series for a Turbo Charged 20v motor effectively doubling the bhp? Thats what REIS covered me in my Elise for. Didn't even blink an eye. Great prices too. They also include cover for 4 track days a year as well

The insurance is through Chaucer and having just gone through the claims process with them (a large one!) I've got no complaints there either. In fact I've just insured the M3 with Chaucer (via Sky)

reis will insure this car with all mods for £1000 for 26 year old..... i will be ringing them back to take on this insurance. very good quote imo... and this covers me with 4 tracks a year.....

[M@r]{]

£1000!!! Can't argue with that.
