..........be careful. The reason your car dynoed so high post flash is probably because your car is running too lean after the Kleemann program was removed. Check your a/f ratios, especially if you plan on adding an even larger crank pulley.

Ted thanks for the feedback. We did in fact check the a/f during the 3 pulls. It seems to very rich. It seemed to be in the high 10's to low 11-1 from like 3k to redline and just got progressively fatter.

This morning we will dyno it again with all the changes and check a/f changes due to the mods. That will determine if we change the tune. I'll post the sheet and would appreciate feed back.

Thanks!

Watch that video..

at 2:41 you can see the S/C pulley. It looks smaller.. First one I have ever seen that looks like it has been changed.. I didn't think it could be done..
Hmm, I see a Vrus smaller upper pulley, along with ASP lower pulley =18psi..
It also says in the video description, "smaller s/c pulley".

You have a good eye!!!

The car on that video is running a Carlsson Pulley upgrade kit. The dead giveaway is the snout on the S/C and the greenish coloured tensioner on the left..

Running anything more than ASP pulley is asking for trouble unless a serious intercooler upgrade is put on to help combat the extra heat the motor will generate.

I am in the process of dismantling my spare S/C and having a shop look over the electro-magnetic clutch assembly.. My CNC shop will be able to make a new pulley without a problem.. I just dont know if it will make matters worse or not..

Also.. whoever owns that car... .. that thing accelerates like mad!!! I cant beleive it only put down 475rwhp because that 4th gear pull looked like 3rd gear to me (unless the video was sped up)...

do you know the Carlsson web address for the US??

............I spoke with Herman Motive today and the s/c pulley in the video is stock. It is not a smaller s/c pulley. They did use a larger crankshaft pulley like everyone else.

Ted

Nope.. It's not stock.. The pulley on the S/C is not a stock one. Go look at pics that I have posted and others have posted of our engine bays.. Then look at the snout of that car.. That S/C pulley is a CARLSSON pulley.. Notice the shield that surrounds the pulley with the holes around it... Stock pulley is solid with no holes and is black in colour. Maybe the owner of the car purchased it used and didnt realize it had the carlssson pulley on and they put a bigger crank pulley on also which would increase boost even further...

Then again, I could just be loosing my marbles here...

Ted Baldwin

......well, I agree with you that it doesn't look stock in the video. I called them today to find out about it. We even talked about the video. They told me point blank that the pulley is not a smaller pulley. I don't know if they driled holes into it to lighten the weight or maybe they just lied to me. Here is their number 310-618-0284. Call them. I am very interested. If you get a different answer let us know.

so vic plannin on fabricating a smaller s/c pulley system? if so im in for a group buy..

ScottCLS55

That pulley in the video is totally different then my pulley.
I'll leave it up to a forensic's team to measure the digital picture and see if the 2 pulleys are the same size. I don't know how to save a screenshot of the other pulley in the video. That would be helpful.

My eyes say its smaller, based on the tensioner pulley, but the tensioner pulley is different on that car also?


Maybe the pulley in the video is the 03 style and my pulley is 06 style?

Ted Baldwin

...........So where do we get this pulley from? Is it manufactured with the s/c clutch still integrated? The guys that shot the video claim it is stock. I called them hoping they will point us to the right direction. I concede that they may not know that is not stock. If so, then where to get this pulley?

I'd love to be proved wrong ... but I'm pretty certain that Carlsson simply supplies a cover over the stock SC pulley. I have no idea why. A way to check this is to eyeball the vertical space from the belt to the "rivets" on the spring-load mechanism. Even if Carlsson supplies a smaller pulley, it's not by much.

Pretty much everything else is changed, however, including the tensioner. Also, the neat tensioner stop bolt is supplied in their kits, from the video I don't know if that has been installed. Heck, the tensioner and the stop bolt probably help quite a bit.

They change the crankshaft pulley like the others ... they change a lot of stuff.

The 03 and 06 style clutches look the same, the contact facing on the clutch is noticeably different. Voice of experience on that one, my 03 clutch failed.
