Studd, nothing will happen. Just dont take it past 5k. I stomped on mine a few times but like I said keep it under 5k and get the tune.

studd143

Ok thanks a lot.

studd143

Just curious.. What happens after 5k?

AKnight55

Your going to be running more boost than before and your ecu isnt tuned for that.. Why dont you go ahead and find out

kustom2k1

As you wind up the motor the supercharger will spin faster forcing more air into your motor. The cars ECU will see the added volume of air and compensate with more fuel but you should get the car tuned to be on the safe side.

studd143

Ok thanks everyone I appreciate the knowledge!

There is some dangerous information in this thread. All I will say is be very careful running more boost with no tune, sure the ecu can compensate to a certain point. No way I would chance it with a $70k motor.

studd143

True! I'll be getting the eurocharged re-tune 1-2 days after the pulley install, depending on their availability. Currently, I have just the normal Eurocharged tune.

I think people need to do more research on parts before they just slap them on their car..What are you even doing installing a s/c pulley on your car if you dont know what it does

I got mind installed and waiting for the tune now, I do worried about the AFR so I haven't been running more than 5K rpm too. just wonder if people with the new s/c pulley still get the chrip? I already put the 2 shims that came together, should I add some more? Thanks for the inputs.

kustom2k1

I forgot about the chirp, going to listen it for it.

Hulk

Your is fine kustom, you are getting paranoid lol

Btw chawkins this engine is not $70k anymore

kustom2k1

Hulk, When your suing for damages it is, ask any lawyer.

Hulk

Shat ap

kustom2k1

eh you shat ap...hey wait a minute...how are your hands free to type when your day job is the two hander? Get back to work!

Hulk

Don't worry I'm not going to steal your job, 2 handing is an art that I leave to you lol

studd143

The pulley has been installed and my buddy told me he didn't see the need for the shims...hmm. I'll keep it and perhaps after break-in I'll need it. I think mines came with 3-4. I'm just waiting on the Eurocharged guy to come and retune now.

Hulk

If the stock sc pulley needed shims this one surely will

Toadster

so there's a break in period for S/C pulleys?

Hulk

No , first time I hear lol

studd143

I got the tune done! Ecu is in learning phase but sc engagement is smooth and you can feel and see the difference! Drivability is great stable and it never feels odd with added power... More to come...

I have this s/c pulley and a 3-piece ASP pulley set going on my car next weekend along with a new Gates HD green belt. Can't wait to get rid of the herky/jerky boost engagement and add more power! Jerry's going to retune it next month when he's out here for EC dyno day in SF. I just can't leave my vehicles stock, it's a sickness lol.

Kickem

Maybe I'll see you there next month weelr... Can't wait to have Jerry dyno tune the Beast!

Since this thread is back to the top I guess I might as well chime in with a progress report on my new s/c pulley. After getting off to a little bit of a rocky start with the initial shim set up, the pulley has performed flawlessly for the last couple thousand miles. Engagement is very solid and there is no belt slippage or signs of wear to the pulley... Just ask the C6 Corvette I smoked the other day. We went from a slow roll up to about about 90 mph and I walked away from him so bad that he wouldn't even pull up next to me afterwards. He turned tail at the first opportunity never to be seen again.

I'm in San Jose, would you mind meeting up I really want to check out this pulley?

mrweelr

Sure, we can meetup after I get everything installed and will post impressions once the new pulleys are on.
