going to make supercharger install similar to that one



but A/C will be kept and the WP will be replaced with electric WP. thus the bigger crankshaft pulley section will force only the supercharger behind the engine. the supercharger pulley is 6 rib pulley, and the original crankshaft pulley is 2x4 rib sections, so need a custom crankshaft pulley similar to original E engine pulley but the bigger section would be 6 rib instead of 4 rib, to force the supercharger with 6pk series belt.





found few feedbacks about CDFRacing, they produce a full set of lightweight pulleys, including adjustable cam, for E engines, as well as many other cars. I decided to contact them instead of trying any similar local service.

they produced exactly what I need







the pulley is machined from a billet aluminum quite neatly, and appears to be a quality part





there will be 6pk belt on bigger section to force the supercharger, and 4pk belt on smaller section to force the accessories





the production of the pulley took a time a bit, but that was a custom work, not from their stock

Is that going to fit in a starlet? Or a large hole in the bulkhead?

thanks Mo3,

I'm from Russia.

the SC on the install photo is a SC12, but I will use SC14.

I found that photo of SC12 install, with a lack of description unfortunately, somewhere on this forum I believe.

got a new one from yahoo



it will go behind the engine similar to that install, SC12 and SC14 external dimensions are almost identical (the SC14 with different pulley below is a previa's one)





in addition the WP will be replaced with electric WP to free more space behind the engine.

it will run with pulleybros 103mm clutched pulley, so I believe 10psi will not be a limit for a 1.5l engine...

You may find that the pulley brothers pulley may slip at that boost level. It was designed for use on Holden Commodores at 6-8PSI boost. Any more and the pulley won't be able to hold. I'm going to be doing a few tests to see how much torque the various pulleys can hold to compare them.

I am in contact with the family who run pulley bros now (as the guy who started it died a while back in a car accident) and have sourced a few electromagnets from them so I can rewind them with thicker wire to produce more clamping force.

I have just installed a 103mm pulley onto an SC14 on a 4AGZE in an AW11 MR2, and make no boost as the pulley slips at 9 PSI (which is reached almost instantly). We should be making around 14-15PSI. Hopefully the rewind will fix this.

Also, with a 1.5L engine, a stock pulley with an SC14 will net you 10PSI (or more) with no worries. I have a 4AGZE in my Levin with an SC12 and stock pulleys, and with cam gears, ABV mod, and a 3SGTE throttle body (from a Gen 2 Celica) I make a consistent 11PSI.



Also, if you do go for the pulley brothers pulley, be sure to give the clutch and pulley face a skim on a lathe to ensure they are *perfectly* flat, otherwise you WILL see slip. You only need a fraction of a mm for there to be a problem.

The stock pully should hold wateva boost you push thru it
I had a 4agze 101 motor & exhaust pod & done the vec lines like HKS do to hold more boost & had 16psi,
but if you put the vec lines like normal they hold 14-15
the stock 101 gze has 9 psi all the non air-flow meter motors runn 9 psi if it don't the you charger belt it slipping but you can't hear it, so titen the belt hard smile.gif

Yea, the stock pulley has been proven to hold more boost than the supercharger can handle.

Also, use a Gates belt, they are the best and are proven to slip the least.




Oh, the chargers are only designed for a long term boost ratio of 1.8 (or 12 PSI), and 2.0 (14.7 PSI) short term.
Here's the manufacturers specs (TX12 = SC12, TX15 = SC14)
