Speedriven1

Hey, guys - just letting everyone know about Speedriven's SPRING SALE to celebrate everyone finally getting their cars out of storage and actually driving them (especially up here in Chicago - it's like the Gallardos are falling from the sky!).

You can check out the details here: http://speedriven.com/mailers/apr12_spring-sale.html

Bummer... nothing for W221

All of that works on the W221, but you don't need the TCU upgrade on the W221 so the prices are a bit different.

I have a RennTech ECU and TCU Tune. How much power can I expect from your intake set up with your IC Pump? Any deals for both?

I honestly couldn't tell you - the tune is about the same on a stock car (I can't feel a difference) but the Speedriven TCU tune has a significantly better feel. The intakes should give you a bit better effect than RT's CF airbox, but without the eye-candy, obviously, and I'd predict it would respond the same from the increased airflow as the RT tune does with the airbox, so 10-15 hp? That's a guess, but I'd say it's solid.

As for the intercooler, replacing just the pump is counter-productive (increased flow across the stock system increases pressure, more pressure = more heat - that's not "shop v. shop" banter, it's physics). RT (in the past) added an additional Mercedes heat exchanger - Speedriven is now offering a massive heat ex. that is well over 200% the capacity of the standard system. More capacity, more time spent in cooling air, less pressure drop across the core (because it's a more efficient core than the MB units from the factory) means superior cooling.

Pic below, and a pic installed in a CL600, so you can see how it looks.

I get what you're saying but if this is truly the case then why does Speedriven offer just the pump their stage 1 kit? I do want to upgrade the HE at some point.
