So i went to Evosport last night and got the car baseline dyno'd on the house. They are going to start developing performance parts for the M271 motors, To start a Pulley kit for the SC.

Anyway, these are the numbers we got on a stock car.

We got 159.7 whp and 163.5 tq on a cold run

We then did a second run and the car due to heat and/or real world issues lost about 6hp/5tq.

On the third consecutive run without rest we pulled in 150 whp/155wtq

We then did an open air box run and gained about 6whp...

That's a nice gain from an open air box! anyway, i will be going to back in about 3 weeks to get the prototype pulley kit in and run some dyno's.. I'll let you all know how that goes.

oh, and Evosport will also design a new intake system for the car. 6hp gain is impressive!

What would happen if your engine blows or your supercharger freezes???

i doubt that will happen! its not like this is a foriegn concept.

Which pullies are they going to change? If they need another test mule, I am close enough. They did a great job on my C32 front brakes.

I believe the only pullies that can be changed are the alternator ( to turn slower and use less power) made larger, and the crank pulley, made larger to turn the supercharger faster. There are issues with the M271 fitment as some pullies are already very large.

I can easily believe the heat issues, the intercooler is not large enoughand gets heat soaked easily on the M271. A good dyno development of intercooler upgrade would sell a lot of new intercoolers for Evosport!

It will be interesting to see what kind of numbers the pullies will produce. Can't wait to see the results.

Also, Does air/fuel ratio (ECU) or infact any other computer needs to be reprogrammed after pulley has been swapped? Since More boost, usually means more fuel is needed for the extra air going into the engine.

ill be waiting inline for the pulley kit..

That's great that Vadim took the challenge, he's a good tuner.

I will be hosting a group buy on this stuff soon, so keep an eye out for it.

thanks!

He'll have to drive an even slower C240.

I hate BS posts like this.

Sauceboy01

agreed

Jon200

so the protype pulley set is for the 230K engine only?

Buellwinkle

All the other engines have pulley kits already, the C240, C320, C32, E55 what's the issue?

CitronC230K_03

long over due too!

It would be nice to see what kind of performance gain is seen with the addition of a K&N filter before the pulley is installed.

CitronC230K_03

the intake would give you more hp gain though, right?

Sauceboy01

well, what they realized when looking at the stock intake box was the fact that the upper cover is really restrictive. So they are probably going to design something w/ that in mind (maybe a new upper cover, and an intake filter, or even a full intake set up. That's what i was under the impression might happen..

I'll keep you all posted as I learn more about their plans!

CitronC230K_03

cool thanks. im really interested in getting a pully/intake combo so you can count me in for a GB!

Sauceboy01

sounds good, i'll keep you all posted on when the Group Buy will take place.

Count me in too.......I need more power!

I've been waiting for this since I bought my car!!! I cant wait for it to be complete! I am in!!! Keep us all posted. Thanks!!!!!

hey danny, increasing the hp of the engine, i wouldnt think would be over streesing it. what are the current stresses on the engine, if you know.

Saprissa

I wouldn't do it.

CitronC230K_03

why?
