great job code 3. i'm also wondering wat if someone has the 181 or the 185 pullies will they work? or do they have to go back to the stock pullies??

DarkXerox

Good idea, this is something that might be useful on long trips etc. Brandon, maybe you could design two different shrouds for the filter (at a price option of course)? One with the full opening like there already is and a 2nd snap on that restricts the inlet?

A few posts above yours the C3P guy mensions using a 179mm with his SC pulley on an SRT-6 crossfire and he was getting 19.5 psi

Keep the reviews coming forward!

WHAT you guys got free M&M's .. sweeetttttttttttt..My order is in..lolol

As for the intake how long of a job is that?? Is it quick enough to exhange for stock on long drives or if you get irrated by the noise..

Stock boost is 14.7. With a 178 pulley you'll see around 17 psi. Not sure on the 181 but I thought it was around 18 ish psi but not sure on that. I know Erik has the amswer to that

kindafast

Nub question
But what exactly does psi do to performance? And where is it measured?

bud4ya

It is the boost the the S/C runs at. Higher the boost the more HP/TQ

Basically it's the air pressure coming out of the supercharger. The more air you force into the engine, the more oxygen, so the more power. Evidently the ECU on these cars is pretty smart so it will automatically adapt to the increase in oxygen by automagically supplying more fuel too. You can get boost gauges that tie in to give you the PSI which is being put out. As to where it's measured...you know, I'm not sure. On a turbo you just measure off the engine intake after the turbo. I guess it's the same on a supercharger (?).

Okay thanks!

brief report: ASP pulley+SC pulley

Just got mine installed and tested, here is the review:

Installation: I had a VERY hard time pulling the old pulley out, it took me and my mechanic 45mins to do so, and for some reason, my mechanic broke the screw, then we had to use a solid screw instead. (MB doesn't sell this hollow screw along, damn..I am not sure whether it would break one day) other parts are quite easy though.

After the installation, I had a few hard runs from dead stop till the end of the 2 gear, car was definitely pulled harder once the SC kicked in, I would say SC along adds up around 10-15hp throughout the range from 2500rpm-6200rpm. As for the belt slippage, yes it occured after 2-3 hard runs, but it was totally acceptable. No major problem YET, and I'm satified so far.

Sounds nice...please dyno and also can I ask if you had a Tune already with the ASP pullies?

+1 taking the stock pulley off for the first time was a *******.

*** Update *** read this to save yourself $60.00 and some time

After installation of the Code III pulley, I shredded the serpentine belt. Literally and figuratively. The car ran very hard (and well) for a few miles and then the belt went. I sent Brandon the photos. Best we can figure out is that the "pulley" shredded the belt. His theory is that I had ran it on the side of a pulley, BUT when we took it apart, it was properly on all the pulleys and guides. I installed another and "let it wear in" yesterday with a 100 mile run staying out of the supercharger. The belt is slightly frayed on the inside (closer to engine than front). I will watch for wear the next week or so.

One thing we noticed after the install. When the supercharger engages, it tries to pull the serpentine belt "in" closer to the clutch. This is exactly where I had the wear and fraying. In other words, it was pulling toward the supercharger hub assembly under load. This will probably not be a problem with a crank pulley. Anyone frayed a belt yet??

Best thing I can recommend is to let the pulley and belt become familiar before getting on it.

Newzchspy,

Thanks for sharing!

IMHO, this is EXACTLY the reason why big tuners charge more... they do a TON of R&D prior to selling to the public. I'm not bashing Brandon (or Code3, since they're one and the same), because it really sounds like he tested this quite a bit on his car and a couple others (i.e. Top Gun), however the fact that he's already come out and stated "the cuts in the pulley are pretty aggressive. The cuts will start to wear in very quickly. Its actually the only thing we are changing in the next run. The cuts will be less aggressive, v-shaped, and not bottomed out in the groove" confirms that, in the end, it's the early adopters who wind up providing the extensive "R" so the manufacturer/vendor can continue the "D" through subsequent product versions.

You pays your money and you takes your chances...

That said, I'm anxious to see what people's results are with the Code3 S/C pulley Version 2, once they're installed and used for awhile

Great info guys. Thanks to all of you for the valuable data.

I can't point a finger here. Just stating the fact that I shredded the s belt. Who's at fault, who knows?? I did get on it within about 10 minutes of the install. Although, in fairness to me, I did check the guides and all before starting it and also ran it for about 5 minutes at idle and at speed before taking it on the road. We also noticed that (before the road test) that the belt was pulling in (toward the supercharger) when the supercharger engaged and this is exactly WHERE the belt was shredding. ON the other hand, I drove it with a new belt to the AutoBahn Country Club for the Lexus Ultimate drive event without a problem, so maybe "wear-in" is an issue. This was a round trip of about 130 miles. During that time I did get on the supercharger without a problem, although the inside of the belt is slightly frayed. Issue, I dont know???

As an aside, after the Lexus event, everyone was all pumped and as we left, I watched an M5 dust an older model Vette. At the next light going toward I-88, I pulled up next to the Beemer (probably a 3 year old M 5) and was able to at least "stay" with him or real close. He had me beat, BUT not by much. On the highway, An Audi with the 4.2 / 8 was dispatched easily. Same thing with the old man in the Maserati. The Audi gave me a thumbs up , the old man a menacing grin. I said to myself You paid what for what???

I will watch the belt issue. Just stating what I know. The installation was easy and is really a no brainer. It does what he says it does as far as torque and performance and I am running all stock except for the pulley. Even the intake and filters are stock. No Magnacors or plugs either. The car is stronger for sure. I just had a concern about the belt wear. I called him, he was great and called me back. His customer service has been great too. He even offered to send me a new belt. He also offered to send a next gen pulley, so hes been more than fair to me.

Note: My car's belt has 22 K miles on it, so its not that old. I dont know how long the belts last before needing replacement. Was my belt just old and the cause. Again, I dont know???

I can't wait to see the dyno from the S/C pulley and crank pulley together!!

Code3 Performance

Misalignment is the number one issue for belt shredding. Its very common when belts or pulleys are not installed correctly. Belt wear was a HUGE factor during testing. Honestly Glenn, it sound like you need to space the pulley out a bit more. The pulley doesn't move when it engages, only the backplate does. If you need more spacers, I can send them your way.

Hello, I thought I would post my review of the Code 3 pulley and intake on my SRT6. I have put 200 miles on it so far with no belt problems and no signs of any wear or belt dust. I am using a Goodyear GatorBack belt that I installed a little over a month ago.

The intake makes the S/C sound sick, much more whine over the cold air intake with the filter in the grill like I had before. Throttle response is better and the power is much improved through all the gears. It puts you back in the seat and keeps you there. My car runs 12.40's and it feels like it picked up a couple tenths. I plan on taking it to the track this week to see for sure. Then I will be at US 41 on the 17th for the private track rental, see some of you there.

Newzchspy

Just so you know, I never said the pulley moves, the belt was moving back off the pulley when the electromagnetic clutch engaged. It was as if the belt was being pulled toward the backplate & clutch and then when you let off to go back to idle, the belt would go back to the normal position. Again, I think the issue is resolved now that the belt has worn in with the pulley (together). Cant wait for the intake to test em both together!!! As I took a good look at it from the drivers side toward the supercharger pulley and the top guide pulley about three (3) inches away, its possible that as the supercharger engaged and the belt moved in, the belt started hitting the guide pulley bracket and was shredded by that. Because you decreased the diameter of the pulley, there is more of a "hump" if you will from the guide pulley toward the supercharger pulley. With the stock pulley, the belt rode straight off the guide pulley to the supercharger pulley. Note that those dynamics have changed.

To quote Brandon: Belt wear was a HUGE factor during testing.

Why is that? Were any belts damaged during testing???

That would be badazz if you hit a high 11. Are you going to video your runs? I can't wait to get my intake mod!!

Code3 Performance

Belt wear/life was a top priority, as in, not destroying them. We paid special attention to the belt, so it was inspected constantly off of the car. Not one single belt has ever been broken, shredded, or destroyed. In fact, we never saw any awkward or uneven wear either. We tested belt temperature, both internal and external, to verify we were within proper operating temperatures. We also cut a few belts in half after they accumulated some heavy miles to take measurements for rib wear as well. The only type of wear we ever saw, was some minor glazing between ribs during early prototypes, which was a sign of slipping. Other than that, never any issues.
