Bill good job. Does the excess metal on the bracket serve any purpose under the snout?

You only added a pulley to try and keep up with us S2'*

Only there to offer alternate idler locations for now (in case I go smaller on the idler so I can move it farther to the left for more wrap) and to protect the 3 plug wires and main battery/alternator feed and ICM harness directly under the SC nosedrive in case the testing goes nuts and I start flinging rubber belts all over in there.

Cool..I figured it could be used if you went smaller...or possibly to move the pulley further under. Maybe an adjustable position/belt length situation.

I thought of a slot, but considering I only used 1/8" steel, I was afraid the slot would rob too much stiffness from the bracket.

BTW, there'* an opportunity to stiffen this sucker up if it ever needs it. The top bolt to the engine block for the Torque-Axis mount is directly below this pulley.

I wouldn't consider a slider. There'* too much opporutinty for the tension on the belt to cause you issues.

I'd think maybe and A B C hole system. On A with 2.2 pulley you need a X length belt. On B with 2.0 pulley the same X length belt ...

See what I'm getting at..that way a betl size could be more standardized. Easier to sell and market with only one belt and adjustable pulley sizes.

This really comes to mind if you had to pull a bolt and spacer to change a belt.. Makes pulley swapping much less work. (However..being S1.. you don't need to pull the bolt or spacer)

That'* a good point, and there is room on the bracket to drill at least 3 holes as long as you space them down and to the left. A diagonal line up and to the front (on axis going down towards the WP pulley).

Here'* a pic of the prototype spare bracket:



And a comparison of the 93 SSEi beltwrap with the new idler compared to a bone-stock (the SLEeper) with all stock belt sizes. Note the improved wrap even when compared to the stock SC pulley setup:

The SSEi is taking two round trips to Northern California the next two weekends for some long trip testing. This includes crossing a major mountain pass (Siskiyou summit) and many smaller climbs. It'll be put to the test for sure. Guess where the spare belt is coming from for those trips?

Donor car !

I've got two Gates Micro-V belts on the SSEi (did that for testing) and two Gatorbacks on the 95. I think I'll swap them for the CA trips, and take the Gates along just in case.

I'll be machining two new nuts down by .1 inches (.050 each face to maintain parallelism) after work tonight, and should end up with more than twice as much belt clearance to the idler bracket as there is now.

This was determined by measuring how far off-center the belt is riding on the idler face (0.2"). The belt will be centered by this evening.

My server is temporarily down it seems. I can't FTP to it either.

EDIT: Server is back, pics work again.

I machined my nuts today. Ok, HEX nuts. It didn't hurt. These are the two nuts that capture the ICM and battery grounds to the ICM bracket studs, and are BEHIND my new idler bracket. This allows me to move the idler a tenth of an inch farther away from the belt. I removed 50 thousands off each face on the mill:



This is the belt/brackt offset before (.050" or so):


And this is the offset now. Somewhere between .100 and .125". Very comfortable now:


Belt is tracking straight and true, very happy with the results. Accelleration is MUCH stronger because of this. I obviously had belt slip on accelleration before and didn't even know it. Now I'm going to switch belts between the cars so I can get the noise POS Gates Micro-V belts off the Zilla and put the Gatorbacks (with only 2k miles on them) back on the car that'* fun to drive.
