Yeah twin scroll housings used to come in a 0.78 A/R housing option only but over the last year now they've added the 0.63, 0.82, and the 1.06 A/R options for both T3 and T4 flanged Garrett GT family turbos.
I ordered my whole turbo kit from Full Race so I'm not sure who makes those housings for these, I'm guessing it's from ATP!!!
My friend's 2.2L SR20 on a 3076R twin scroll single waste gate setup on pump gas 21 psi made over 500rwhp on dynapack! I'm sure my 2.4L full built stroker block will hit the 500 mark on pump.
I trust my tuner Koji to do a reliable tune while achieving the most hp and torque at the same time, sure you can mess with timing and fuel to achieve higher hp on the dyno but it's not good in the long run. As long as the power band curve is good I'm happy!
We'll have to wait till dyno day! I'll have videos and detailed charts to post![/QUOTE]
huh,cool man..wow,thats sick that your buddy made that kinda power,and on a dynopak WTF!!!it makes ma more optomistic for my pumpgas goals.im 2.2 fully built ve head with ve pistons with full race t4 t/s 6262.im hoping i can get close to 550 on pump.i really admire the attention to detail in getting it right the first time around.ive been messing with this setup for about a year and a half,anf hoping to have it on the road by december.ill be watching this thread closely.goodluck with all aspects of it!!and try not to get depressed about the money your spending on it like myself..lol..
