Thank you for the info on dynoing and thanks for posting your numbers.

 

Which EC SC pulley? 61 or 64.7 ?

 

From the boost number it's a 65 mm pulley.

Cool! Thanks for posting.

 

It only gave me 3 PSI if that tells you, although I'm betting the gains are less at altitude. I asked them for the smaller pulley and was told they only had one pulley. I gained just as much with the Needswings DCAI.

 

With my Code 3 at sea level I saw a maximum of 17.9 PSI. With a 178 ASP crank pulley I see a maximum of 19 PSI at sea level. Just so people know, more or less what to expect.

Always different on different cars, location, measuring. But I guess a 61mm could give 20 psi boost. Maybe somewhat less than a 185 crank pulley.

 

Actually it should be slightly more than the 185 pulley. The pulley ratio is slightly higher.

These new 62/61 mm pulleys should make some GREAT HP. Exciting times!!

Awesome numbers! Great news! Just got myself the 61mm. The 64.7 I have today will be put on the shelf together with stock. Unless someone will buy it

 

It sucks that the guys at higher altitudes are getting such low uncorrected numbers. I'm very glad to be at sea level.
