Isn't the sc14 from the 4AGZE and a sc21 from the 1GGZE!

yup, although i thought it was an sc20

the thing i dont think people realise about the sc14 vs the eaton blower on the supercharged 6's is how close they are in size, SC14 is 5% smaller than the M90. m90 is 1.475 litre, sc14 is 1.4. not that big a difference


there is quite a few puttin about 150rwkw running 8psi, with just rising rate fuel reg on street commodres

There is a lot more to PD blowers than just physical size and volume of air displaced

For starters I'm pretty sure the SC14 is a 2 lobe plastic rotor setup, whereas the Eaton m90 has 3 lobe teflon coated rotors. The reason the SC14 are clutch driven is they are not meant to be used all the time - you will find a lot of seals tend to fuck out if being constantly used meaning it is a *meow* to source parts. The SC14's were never meant to spin at higher than ~12000rpm, which is why very very few people run higher boost. I was spinning my old m90 at ~14000rpm all day everyday, while others that were cooled and running over 20psi were spinning the blowers at well over 20000rpm with no problems at all. Started to get heat issues and power loss but no damage to the blower itself. The m90 is a far more efficient blower and much tougher than the SC14.

Yeah they are both roots blowers and are retty inefficient, a twin screw would be nice but then we are talking some serious dosh for a Whipple or similar setup.

Pretty sure the 4A-GZE came with a SC12 charger while the 1G-GZE came with the SC14.

i wasnt tryin to say its as good as a m90, the m90 has a 30 degree helix which aids in effieceny, i think some of the new wipples have 120 degrees, whilst the old sc14 has next to nothing. , if ur going to buy a m90, heads inlet etc etc, u may as well get a l67 for the tougher bottom end, but most of them are still going around 2 grand from when i last looked.

bang for buck, i dont think the sc14's are as bad as everyone says

[ANYTIME]

thats what i was thinking if i can pick up a SC14 for around $400 and make the bracket myself.. qld ignition leads are 3 doors up the road so they will be able to hook me up with some longer leads.. so it will be a cheap upgrade...
