I couldn't get hp tuners to lock the trans in third on the dyno
Had to roll into it at about 3500 to keep it from downshifting so the graph looks a little soggy down low
This is at 17.8 psi on the highest pull
The first pull spun the tires pretty badly
Despite the difficulties with the dyno run, the results still look solid.
It appears that once you are in boost, the power is really smooth and linear. I would imagine that makes for a predictable and confidence-inspiring vehicle that is fun to drive.
I had a maggie on the car before
Power delivery was instant and violent, but tapered off up top
Now it's very progressive and pulls hard all the way to redline
I'm definitely happy with the choice of two small turbos
Street driving can be done out of boost if you want, but a liiiittle more throttle input and they light off quickly
$579 for a china turbo! An S366 is cheaper and will make more power I'd bet. The 1.25 t4 75-76mm single seem to make more power per pound than the T3 china twins. Wonder what the back pressure is on those... (*hint*hint* hook us up with the data mkvamso!)
I'm using the cast wheel t4 flanged gt35s
I bought their hotside kit, so the bigger turbos were only a few hundred bucks for the pair over the tiny base turbos
It's a tight fit with these even
A pair of s366 would definitely be a nicer set of turbos, but I doubt they spool as fast, and they're physically much larger.
I have a pair of 02 bungs I didn't end up using, I could probably measure back pressure fairly easily, just haven't really gotten around to it
I'm sure it's a little high with the failrly small exhaust wheel, but they carry well to 6900 at over 20psi so I doubt it's excessive on a mild 5.3
