How Gay is this? Not that there's anything wrong with that.

 

Please elaborate. According to EC's numbers on their website, the new SC pulley is approximately equal to the 181. According to them, the same torque claims for both. Doing the math on the new 64.7mm SC pulley, I came up with 18.7 p.s.i.g.

 

It sounds rather gay I have to admit. Don't you worry, I have my gf right here. But my love to my car is quite intense. It is like the frodo and his servant in lotr. Quite gay but not really. Depends on how you see it. not that it's something wrong with that. (Seinfeld)

 

coutesy of brian brave. look at the s/c rpm #


By my calculations: (based on the stock 74mm S/C Pulley)

Stock Crank Pulley : 74mm S/C - - Ratio = 2.0270
Engine RPM @ 6,000 - - S/C RPM = 12,405
Engine RPM @ 6,200 - - S/C RPM = 12,819 - Rev Limiter W/Tune
Engine RPM @ 7,000 - - S/C RPM = 14,473

178mm Crank Pulley : 74mm S/C - - Ratio = 2.4054
Engine RPM @ 6,000 - - S/C RPM = 14,432
Engine RPM @ 6,200 - - S/C RPM = 14,914 - Rev Limiter W/Tune
Engine RPM @ 7,000 - - S/C RPM = 16,838

181mm Crank Pulley : 74mm S/C - - Ratio = 2.4459
Engine RPM @ 6,000 - - S/C RPM = 14,676
Engine RPM @ 6,200 - - S/C RPM = 15,165 - Rev Limiter W/Tune
Engine RPM @ 7,000 - - S/C RPM = 17,122

185 Crank Pulley : 74mm S/C - - Ratio = 2.5000
Engine RPM @ 6,000 - - S/C RPM = 15,000
Engine RPM @ 6,200 - - S/C RPM = 15,500 - Rev Limiter W/Tune
Engine RPM @ 7,000 - - S/C RPM = 17,500

Using a Stock Crank Pulley, the S/C pulley would need to be reduced to:

63.6mm to equal the boost of 178mm Crank Pulley running @ 6,200 Engine RPM
62.5mm to equal the boost of 181mm Crank Pulley running @ 6,200 Engine RPM
61.2mm to equal the boost of 185mm Crank Pulley running @ 6,200 Engine RPM

If 20,700 is the max S/C RPM; and to be safe we decide to stay 10% under max - that's a target of 18,630 S/C RPM - - (when at 6,200 engine RPM)

Stock Crank Pulley would need a 50.9mm S/C Pulley
178mm Crank Pulley would need a 59.2mm S/C Pulley
181mm Crank Pulley would need a 60.2mm S/C Pulley
185mm Crank Pulley would need a 61.6mm S/C Pulley

Check my numbers to see if I missed something.... because I want to replace my 74mm S/C pulley with a 61.6mm S/C pulley (16.78% smaller)

 

Does anyone have instructions on how to pull the stock pulley?

 

It will give boost, be safe and reliable. Enough for me. Will still be the fastest white srt in my country.
Shame that the srt4 neons can turbo up with agp and reach 10 seconds in the 1/4 mile. Also, what I'd this SHO car kicking a srt6 *** on YouTube?
Can we reach 10 sec?

Thanks that was helpful. I ordered the pulley last night. Any ideas of how the car will feel after install of the new pulley? I just have the Needswings standard cai otherwise the car is stock. thanks again

 

buy tires. all i have to say on that subject! do a tune and you may need some new boxers also!

 

Can't wait to get this on my car along with the headers being developed by Rudy at SPEEDDRIVEN this should put some seat of the pants feel in our cars. BTW thanks for the pdf on the install 32krazy!

 

no problem. btw instead of using a prybar on the pulley to hold it get one of those oil filter wrenches that has the rubber strap and hndle. it works better and doesnt stress the pulley shaft

 

Good Idea as I really don't like to put a pry bar against anything important like the s/c front snout.

 

Any pulleys been received yet.

 

Nope and I emailed Jerry and got no response.

 

The Eurocharged Team is at the Texas Mile and will not return until Monday.

 

As the first guy on the new pulley list, I promise that I will post as soon as I hear anything, or when I receive it. It is exciting and tough to be patient, I do know. They did say the end of October, so at this point it's not right to be impatient. Be .

 

I spoke with the Houston guys yesterday and they told me packing and shipping starting next week......but that will be seen when that time comes.

 

Right on schedule, great to hear.

 

I am just excited about what to expect.

The bad news is I will probably have my snow tires on by the time the pulley arrives. Whats worse is the track is closed for the season ,and dosnt reopen until April
