Did not know that you grew too old to fool idiot drivers  Grin  Wink
I just agree its a fine line to becoming that idiot driver yourself: street racing has altready killed too many good people...

This is not Oklahoma and there are no TV crews around Wink   And besides this was in rush hour traffic, not a good place to be making boost Shocked Grin

As I am doing a few changes to the engine I thought I would keep it on original thread for reference so will update this as I go along Smiley

One of the compromises I made last time was on the was on the fan speed, with the big pauter pump and the biggest bottom pulley that would clear it even the smallest available top pulley gave us a ratio way off stock and much lower than even power pulley ratio gives, also the bottom pulley was so close to the pump that to change a fan belt would involve either removing crank pulley or the oil pump.
My idea to solve this was a serpentine belt set up but again nothing available would give us anywhere near stock fan speed so only solution was to make something which is what we are now doing Smiley The finished pulley in pic is smallest I can find & what we are using for measurements for everything except diameter Wink


We also have the gearbox apart as when it was fixed last time some wear on 3rd gear was noted and I don,t want to take any chances this time so it is being replaced with everything else being checked while apart, and also we are adding a sensor to measure input shaft speed

cheers Richie

Nice job on the pulleys!
What were the signs of the former pulley ratio being too small?

As old ECU didn't monitor head temp there is no exact science but we are now the Fueltech and it has the potential to scare me Shocked Cheesy Grin, stock ratio is about 1.57, and we were about 1.36 so at 3500rpm cruising fan is spinning nearly 500rpm slower. one other of our considerations is less availability of E85 this time so if we are running on only 91octane pmp fuel it will need all help it can get on street drives I think

Gday Ritchie.
Some of the green and red tractors/headers (John Deere, Case IH, Meeow Cat if you must) had alternators with really small multirib pulleys, under 2" diameter (ex-John Deere Parts  Wink ).
Since you're in that area, hahaha, maybe worth a look?

I understand the concern! Didn't realize you cruised on E85 last year, but on the upside: you probably need a lot less fill-ups when cruising on 91  Cheesy

Will the stock ratio, the very good 'traction' of a multi-rib pulley and the high RPM of dragracing not be a problem for the fan?

We are going to have 2 different top pulleys so the track only one slows fan right down to stop that exact problem Smiley

How did it go Richie

Not wonderful, the tps failed on 1st pass,plastic tang on inside broke off Angry  but I figured a way to get round it enough to run car so we made 2 more passes but could only run on wastegate spring as all the add ons needed to activate 2step/boost control etc need tps signal to know when to start, good news was gearbox worked good and input shaft sensor works so some positives, and its better that tps failed now than in Virginia at start of drag week!!!

It might be good to take some extra sensors to drag week to be sure?

Do you already have a 356 (= smaller size) top pulley?

Even smaller than that, its 88mm outer diameter and I have shimmed it as far apart in middle as I can to get belt in deeper so tricking it to think its even smaller Grin

Hello! I'm looking for a KIDD Pulley. Unfortunately I can not find it on the internet. Where did you get yours from? Thank you.
