My Alpina Roadster S (supercharger conversion @ ESS)

Hi Brad,

I'm just doing their stage 2 which is supercharger + intercooler with no changes to the engine's internals. According to Asbjorn the TS2+ level with forced induction camshafts wouldn't make much sense on the Alpina engine. Stage 3 with camshafts and custom made lowered compression pistons runs about twice the price of a TS2. The only problem is that they have no idea how strong the Alpina components are, but since it's Alpina they should be very good.

My engine has run 26,000 miles and should be in good condition.

If you are serious about supercharging your car I think this is the time to contact ESS :) .
 
I will, I just didn't want to be the first to do it and have to pay all those development and fabrication charges! :wink: I gave Hans a copy of my MAP a few months ago when he was over here so I knew he was planning something. I think I'll contact him when your done and get him to send me a duplicate kit, could be a fun winter project. Can't wait to hear the results, what kind of power are you expecting?
 
Asbjorn believes he can get it over 400HP with a conservative 6-7PSI boost. I just have to wait and see. I would be satisfied with 911 GT3 power (415-420HP).
 
That sounds about right, I'd be happy with 400 but anything more is a bonus and you can always increase the boost in the future if you get bored! It would be nice to outdrag the old farts in their GT3's at the track too!
 
I think this thread is one of the most interesting and that Z4 is one of the nicest on this forum (it would look better if it was a coupe mind! :P ). :thumbsup:

If I keep my Z4 then I am thinking of the ESS route. There is a dealer not far from me that fits the kits. :D

ROTFLMFAO-PWNED!!!

:rofl: I can just imagine you guys waiting to come back with that one for ages now!! :thumbsup:

True, but it will be cheaper to do than the deal I was offered on an M, it will sound awesome (I miss the supercharger sound of my JCW MINI), and, given the right straight dual track, I can wave as I go past the M guys!
Oh, and the road tax stays the same and the insurance and servicing costs are cheaper tan an M!! :fuelfire: :poke: :thumbsup:

Mind you, I have my eyes on something else at the moment so it may all change yet! :wink:
 
By the way, if anyone is thinking of this the company is http://www.simpsonmotorsport.com
This is the Email I got back from them:

"Thanks for the enquiry.

Yes we are the UK agents for ESS supercharger products.

The costs for the TS kits are as follows -

The TS1 kit costs £3250 plus vat and fitting takes approx 8 hours.

The TS2 kit costs £4250 plus vat and fitting typically takes 12-14 hours.

We simply charge our normal workshop rate for fitting the conversions and we charge £50 per hour plus vat so this should give you an idea of total cost.

I hope this is of help, please feel free to call if you require further info.

Thanks

Anthony"

Works out around £4,300 all in for the TS1 kit.
Now on their website it say "No superchargers for the Z4 at the moment" but phone them as they do do it.
This was an older SE Z4: http://www.simpsonmotorsport.com/default.asp?id=77&pid=70&name=BMW%20Z4%203.0%20Supercharged

Interestingly they have worked on an Alpina Roadster also: http://www.simpsonmotorsport.com/default.asp?id=144&pid=70&name=Alpina%20Roadster%20S&page=Projects

:D Yeh that's mine!

The info hasn't been updated for 18 months though so a lot has changed since then. I might rewrite it next week when I'm over there. For those of you who don't already know I'm over at Simpsons every week pretending to work!
 
Breaker, did you see the problems Graeme had trying to sell his ESS'd 3.0 he ended up having to split it to sell it, I would suspect that you would be the same. Don't think it is a recommended action at the current time.

What else have you seen?
 
its deffo something we all fancy...but as above a lot of potential buyers dont want a ready done one.

also graemes was in scotland.....

prehaps untill the z's drop in price and maybe appeal to a newer market such modified cars will be more acceptable.

splitting is probably the best way of recouping money
 
Have to agree with Mike and pablo on this. It's an awesome idea to think of and have it, but when you look at what it does to residuals, reduced target sale market insurance, etc. then it's a tough call to actually go with it.

Doesn't mean I don't still want one on mine... :rofl:
 
If someone told you there was a version of your car that had another 100 odd horse power and only cost another few grand you would save up and buy the more powerfull model. Yet doing it 'aftermarket' hits the residuals so hard you just don't want to do it. Shame really as its the biggest bargain going if you think about it. :(

Anyway this thread is salivating stuff, can't wait to hear about it finished :thumbsup:

I like to go for what I like!! No thought processes go on when I want something!! Ask my girlfriend!! :rofl: The sound of a supercharged engine just floats my boat!! :)

I'm keeping an eye on the new Nissan 370Z. :wink: I test drove the 350Z and really liked it, but the Z4 Coupe won me over that time for a number of reasons.
 
Femme didn't post the preview yet from the movie of our trip to ESS Tuning in Norway?
Then I'll do it ;)
