Aurora 3000/4000

[noseamum]

Wondered if anyone has experience with these.
I am considering using an Aurora 4000 on my 89, using eighter stg4 ddps or 5x14 or something like that.Hope is to make 350-420RWHP on #2.
Have 2nd gen IC fitted.
And I can`t find the size on the 4000, think its 63/76/? or something.Will it be too slow/big?
Or should I rather go for a 62 phat shaft instead?

Nobody who has experience with auroras??
What about a s300 or a phatshaft?
Have a hx35 now from a 98 2500 and think it has good spool up, fast enough for me.I was thinking of a Aurora 4000 but haven`t found much about them on the net.So I am considering others.
Any advice would be appreciated

I got a 62/71/14 super phat shaft with 6x16 sticks and have a good spool up of bout 200rpm then its lite like a rocket that weighs in at 6tons! And I love that turbo !!

i have a A3k on my truck. its stock maybe a lil bigger injectors gov spring and fuel screw maxed it lights it pretty quick. really good for what i do but wish it was bigger. i tow and street drive and just full throttle on streets alot. tows great i havent seen anything above 1350 degrees builds 40-45lbs of boost. me personally i could stand a lil more lag. i kinda got it in mind of doing twins later on in the trucks future.
