If anybody is interested in getting a group buy together on the larger Renntech intercooler let me know. I've been talking with Bob Brady of Renntech and he has e-mailed me to let me know that the real deal is now being offered for $995. He did say it could be sold cheaper if they can get enough orders. HP increase is 10. If anybody is in the Houston area it can be installed at Memorial One for alot less than MB North.

What kind of gains could be expected when coupled with pullies, chip, intake, and exhaust?

VW owner strongly considering going for used 2002 coupe in spring 2003.

Also how much work is it to install that intercooler?

Welcome to the board. The intercooler is good for about 10 to 15 hp. The stock intercooler isn't very big and get heat soaked very quickly. The pulley is good for about 30 hp and about 48 ft-lbs of torque. The is no CAI made at this time you'll have to make your own. Those who hve say 6 hp. Exhaust changes such a muffler or catback system are about 4 hp. A much larger gain can be made with a header, but no one on the boards has done that.

To install the intercooler, the front bumper must be removed, and the fog lights and temperature sensor disconnected. The old intercooler is removed. Test fit the new intercooler and drill four holes for the now mounts. Felt is applied to the air con lines and to whatever might rub on the new intercooler. Mount the intercooler, connect the hoses. Reconnect fogs and temp sensor and replace bumper.

Kleeman is working on replacing the Eaton rootes type supercharger with a larger Lysholm twin screw supercharger. It is suppsed to cost $3000 and increase the rwhp by 100 hp, with no other mods.

Yeah but if you throw a huge twin screw on there and creat killer PSI won't you have detonation issues and car just retard timming unless you run race gas?

So the header is proven to be a bit of a weak spot? I would have to wait and see results of replacement header before I would think that route.

I assume the eaton used on coupe is the little eaton one.

I have already heard from some more reading (man there is allot) that Cold air setups aren't really creating much benifit. I wonder how well car does with combination of improvements..

Thanks for info I will be lurking these forums for quite some time.. My first goal this winter is to buy house. Then next year new car thoughts will come into play.

Even though the boost from the lysholm is much greater the temperature of the air coming out of it is much lower than that of the Eaton M45. Also, Kleemann will use a rising rate fuel regulator to richen the air, fuel mixture.

Cool so the right pulley, chip, header, intercooler, regulator on a eaton setup will prolly gain pretty good too then?

The ASP and Kleemann pulleys are already as big as they can be. It is difficult to change in pulley on the supercharger. No "tuners" offer that, but one person had one custom made. It wasn't cheap. The only fuel system mod that I am aware of is made by Vaeth and must be shipped for Germany. There are two ECU mods available. The Upsolute mod is $500 plus $75 installation. Dyno results that have been posted have been very disappointing, although a couple of people swear by them. The Renntech mod has not been purchased by anyone on any of the boards. It costs $1600 plus installation.

I cannot imagine a chip will work well for setup if it has diff pully, intake, exhaust, and intercooler.. Allot changes there.

I think so too... :?

What are the HP gains from a Renntech ECU chip install? Does Renntech have a website?

I really want the intercooler too???
how mcuh would it be If we get enough ppl to buy it???
and do U have the pic that the intercooler is installed in the car???

I don't know if it fits an SLK. The group but was done right when they first started to make them. Renntech probably won't do another one.

:lol: Just let me know the details. I am in!!!! Been waiting on some info like this. Always wanted to upgrade my intercooler... I have a question. What about a K&N filter along with intercooler, upsolute chip, eisenman exhaust, pulley upgrade? Good for about 280-300 total hp out of c230k sedan? Thanks, Britt
