SL55 AMG vs. BMW M5 vs......LP640!?!?!?
All three of these twin-turbo engines will be easily tunable with just an ECU/Exhaust/Intake to well over 700 horsepower, and up over 800 with just a little work to the engine also. I guess mid 10's in the quarter will be the norm!!!





I've been considering the cooling upgrade.... but I also want headers to remove the bottleneck

Anyway, w/ cooler weather coming, I should be able to notice a lot easily if I lose power after several hard runs and need to upgrade my cooling first. I know I should get data logger to be completely certain.
BTW, you may have posted in separate thread.... but what kind of numbers are you putting w/ K2?
Well, maybe you can think about doing headers soon, and since the weather is only gonna get colder, you can do the cooling mods in the Spring?
Or do them both at the same time! Lol...
A data logger is key. I can't say for sure what numbers I'm running because I haven't had the chance nor time to put it on the dyno after the mods. Hopefully, I will get to the same dyno machine I used for the baseline sometime next week. I'm expecting a min. increase of 80 rwhp.
I recall from the Evosport ecu/pulley, shorty headers. and phenolic spacers, I gained around 70-80 rwhp on my e55.
Only reason the window was down was to get better footage for everyone here! And my windows are slightly tinted too, so maybe next time for the 15-20 mph rolls and from a dig we will have someone filming in CH's car.
Thanks!
REALLY Nice guy, very down to earth, Light brown hair, about 35. We talked for about 10min. Super nice. I wonder if this was the same guy?
I tell you, that car was absolutely BESERK!

We've gotta get him on the board!
Thanks man... I really apprieciate it.
Now I just gotta get it up to speed. Thinking a Pulley, 80mm TB, and Re-Tune, along with a CM30 Pump. Then it should be ok.
The Flash from Adam REALLY helped BTW.

I should have asked him, but I didn't remember about your Video till I got home and thought about it... I Did get some pictures of his car with my trusty pocket camera. I'll try and get em' up over the Weekend.
I showed him a shot of my car I had with me, and he loved it... Like I said he was super nice. I'd love to bump into him again, and tell him about the Video

Nice meeting you and Sunny btw, take care dudes.

Glad a nice guy owns it.

BTW, how do you like your ride now with 20s and lowered suspension. Is it a lot harsher than the stock 18s? I've only had 19s on all my cars, 20s are tempting though.
Right on the Front tire size... But on the Rear I'm running a 295/25-20" With a 10.5" Rim. with the most negitive offset I could run the get the tire Underneath the Fender AMAP!
I guess from years of Dragracing... Nothing looks more unsightly to me than tires sticking out!

Plus it throws stuff all over the car. if I could have gotten a 305 all the way under the car I would have done it.
As far as the ride... I drive the car very little, so ride as not as important to me... It's the looks, and I love the way the car is right now... It is a ruffer ride, you have to watch the bumps, If I were in the city, I don't think I could do it, still you must be very careful, and I wait for all the potholes to be fixed after the winter when I put the car back on the road.

And I will keep an eye open for that Murcielago...what a badass.
Thinking about doing a run sometime soon. Wanted to get a dyno this weekend, but was out partying too much for halloween. Haha...
Well, I'm thinking about sending my car out to the dyno later tonight or tomorrow. I'll keep you guys posted.
