SL55/63/65/R230 AMG: WEISTEC Super Charger on a SL 63
Do you see any dynocharts with a C63 making above 600 RWHP from a weistec supercharger?
let me help you......NO, HELL NO
I was expecting alot more power from the Weistec supercharger, atleast high 600-low 700rwhp.
Maybe running high boost can accomplish this accompanied with race gas?

Modding these cars is not easy, their is plenty of low hanging fruit to be picked in getting a C63 in particular to over 500hp at the crank and even 550hp. However from my experience once you go past that figure the dollars needed for every extra hp goes up almost exponentially. This is particualrly true of the higher hp stock models like the SL63 and CLK BS which are already at over 500hp crank in stock form. It might take several times the dollars to add the last 50hp as it did to add the first 50hp via modding a stock car.

I think Graham knows about performance. 1st at Daytona and 3rd at Indy. and he likes his.
This is what he had to say about it after he drove back from his 2nd place finish in his Indy car in Milwaukee.

Just thought I'd give everyone my impressions. I got my car back this weekend in Milwaukee, and drove it around there for a while, then the 270 mile trek home. The car ran flawlessly. So much fun. The combination of the Evosport and Wesitec parts, the car sounds absolutely mean as hell, and is fast as can be. For a daily driver, I dont know what else you could do to have something better rounded and more fun.
On the journey home cruising about 80 I got 20.5 MPG average. Not terrible for 560 rwhp!!!!!!
Absolutely love the car and couldnt thank Steve enough. I think this is something all BS owners should do without any worries or regrets. They will love it!

1- Headers, tune, intakes, ECU, Ported Heads, X pipe, filters---around $14000 and get you to about 630-640 HP, 725 NM tq
2- Weistec supercharger...626 HP, 745 NM $15000
3- Both of the above: around 670 HP 870 NM for around $30000
The weistec comes really in use if you start from stock form. Other than that, its not really worth it.
(just like what you did Mavrick)I still like #1

Like everything you want something for a while and then you gradually forget
it.Don't get me wrong I wouldn't say no to 600 bhp, especially about a year ago, it just takes a few races where you win to make you realize your already
driving a very quick car. Mine has been re mapped and I have K & N filters.
I don't care what others say my cars has 550 bhp rather than stock 525. I
can't remember the last time somebody left me behind, and if they have more
power lets see if he has the guts to use it. I love my car, it drives beautifully
long distance, it's fun, it makes lovely noises and gear changes, and is a convertible, what more could you want. I suppose when your sitting at home
you brain can be pleased by knowing it has 600 rather than 550, but in the light of day you forget it. Even with a supercharger there will always be something faster, you have a great car that 90% of men would give their
right arm for, enjoy it, my car gets looks all the time as well. Save your money
or maybe re map with some filters. What ever you do, you'll still have the best
SL MB has ever made.

But I don't like artificial ones, nowif I could swap the SL for a gorgeous girl with ***** like coat hangers
an natural
, no contest.I suppose the 63 is like the natural ones but maybe a tad small.

Still post the results if you have it done, how much is the cost?

I can definitely feel the power increase. In 50-80km/h driving, dry road during kick down the traction control lights on all the time, much more often than before SC install. I would say at least 30% more power than stock.
