Turbo Lag - Kit
With all of these options out there for kits, Im lost as to which one to buy.
I am a turbo guy so "buy a supercharger" is not for me.
Basically, I want the kit that will have the least amount of lag. Seems like all of them can match my power level requirements.
So, What kit has the quickest spool?

Have a look at this (twin scroll single turbo):
https://my350z.com/forum/forced-indu...from-bp-8.html
Spooled up by 3500rpm to 9psi with a 67mm T4 1.0 a/r turbo:
This is would be about 470whp on the industry standard DJ dyno.

I would like to see how the 6766 T4 1.32 a/r spools on a built engine.

Here's a Greddy TT kit on a 8.5:1 compression at 9psi... I'm not sure if it's a fair comparison or not since I do not know anything about the motor that the above map is based on.
Spools very quick, and you can see the WTQ and WHP are pretty comparable, I prefer the twin setup for more average power band instead of my peak, personal preference.

They are all horrible. at least 45 seconds of lag on any turbo system.
BTW, if you have to ask about "lag" then you probably aren't ready to own a boosted vehicle (or do an install). Most people research and read before they start worrying about the difference between .1 second and .12 second spool times.

on that note a dyno won't show you "lag" it will show you spool time from no gas to WOT at a very low rpm.
Lag is relative to the rpm you are traveling and the size of the turbo. It will take forever for any turbo system to build boost if you are trying to punch the gas at 1500 rpm and race at stop lights like a ricer. Also it depends on how much boost. It takes longer to get to 30psi than it does to 5 psi. If you are at 5k rpms and go WOT there is a lot less spool time than if you are at 3k rpms and go WOT. Any rpm below where a turbo can produce boost is stupid to go WOT with and probably not an rpm any car guy would even try racing at. Transmissions have gears so smart people use them to downshift.
