ATI Damper compatable with FFS coldside?

[pat conlon]

I recall seeing somewhere where the minimum size 6 rib s/c pulley used with the ATI damper would be 150mm... if so, then no go with a pulley that big.....(yea right, someone's gonna do it)

Is the 6 rib s/c belt offset on the ATI ok with the coldside nose pulley?

TIA

Pat Conlon, Palm Desert, Ca. 118* today (but it's a dry heat)

yea, so is my oven...

Hot there today Pat. ONLY 112 here so far.

I guess I am not following the question. Does the ATI come with a 150mm 6 rib pulley in front of the stock 4 rib pulley locations? Is it just a replacement for the stock pulley? Can you aim me at some data/info?

Hey Tom, The ATI Damper comes with a 6 rib supercharger pulley as a option:

IIRC the pulley (located in front of the belts) was sized for folks who had the Uber Whipple ~ 150mm.
I guess I could check with FM to see if a smaller 110-120 pulley would fit the damper.
If 150mm is the smallest pulley that would fit, then to keep coldside in the safe zone a custom 80/85mm nose pulley would be needed. Not sure that big of a nose pulley would work/clear your auto-tensioner That is, even if the ATI s/c pulley lined up with the MP62 nose pulley.

Keep cool amigo...

If it is 150mm, then I have some 75mm 6 rib SC pulleys. 150/75 is the same as 130/65 so it would work the same as my car. :) Without any dimensions, I can't tell if it would work or not? Sorry. All I see is three holes in that pulley so I'm curious how it bolts to the crank hub that has 4 holes? Do they replace that piece as well?

I guess my best answer is that I just don't know. My kit works perfectly well with the stock crank pulley so I also don't know why you would want to spend that $540? If the 6 rib 150mm pulley was properly spaced, I think it would be fun, even with the 65mm pulley on the SC. ;)

Thanks Tom.
Just checking in to see if anyone has used it with your c/s or h/s kits.
As I understand it all pulleys are replaced with the ATI damper, thus the 3 hole.

Here's a sectional blueprint of the damper showing only the 2 stock pulleys:

That looks like it should line up OK. Buy me one and I'll try it for you. I am getting tired of 130/65 anyhow. :)

Don't you have an E-Cool fountain for your pool. :-) We do and it really works.

NOT to be confused with a intercooler, no doubt....;-p

[Tom @ Fast Forward]

Actually, as out pool is in the back yard, we tend to call the fountain mister and outer cooler. Life without E-Cool would be hot. E-Cool is NOT an inter-cooler even though it does cool the air between the supercharger and the engine. Have we covered this ground before? :)

Heh heh....Yes Tom, quite adequately.

[Tom @ Fast Forward]

Well, I can only say that, since we converted the swimming pool to gasoline, it cools a lot faster than when it was water.

...just don't park the BBQ too close! :angel:

I'd be reading about it in the local paper tomorrow! What do they say about 15 minutes of fame ? ? ?

(Is this severe thread drift, or what?)
