Dear All,

i'm owning a 2005 Speedster 200 with two SC Engines each 185Hp without Intercooler.
Mostly the 185Hp and the 215Hp are the same - the two big differents specs are:
- 185 has 8.1 Compression against 8.4 for the 215Hp
- 215Hp has forged Pistons

But when just adding the intercooler to the engine with the lower compression, the power should get much better and even the reliability off the engine, i think.

I've choosen the Intercoolers and fittings from Silicone Intakes - details about that under

Please let me know if somebody else did such a kind of conversion and your thoughts about that

Pictures will follow up, when i've finished my installation

Cheers,
Wolfgang

I would be very surprised if you get a noticeable gain.
