***** AAM Competition's 370Z Twin Turbocharger System *****

V1H

The build is complete! I am probably going to collect my Z tomorrow or Thursday.
Feels surreal that the time has finally come..
Here are some numbers:

DYNO
DynoDynamics in shootout mode
correction method fixed to ATMC2

DRIVEBILITY
Stock Torque exceeded at 2000 rpm.
400 ft-lb (542 Nm) and over available @ 2800-6600 rpm

PEAK VALUES
Flywheel
501 bhp (508 PS) @ 6600 rpm @ 5.8 psi (0.40 bar)
435 ft-lb (590 Nm) @ 4200 rpm @ 7.0 psi (0.48 bar)

Rear Wheel
422 whp @ 6600 rpm @ 5.8 psi (0.40 bar)
367 ft-lb @ 4200 rpm @ 7.0 psi (0.48 bar)

More boost caused Jez having to retard timing to prevent knock which is why more boost did very little more power, hence, we stick to this pretty low boost. The TT kit appears exceptionally efficient, IMHO, needing so little psi to get going. In simple terms:
55% horsepower gain over stock at 40% intake pressure over atmosphere.
59% torque gain over stock at 48% intake pressure over atmosphere.
Of course it’s also the exhaust allowing for that better than 1:1 ratio

Given that this is about half the torque of a 1st Gen Veyron (590 vs 1200 Nm) I am going to properly poop myself when I will be driving it home (4h drive)

Awesome results, V1H!

For those wondering about the power this build is making, Horsham Developments has an awesome dyno comparison calculator on their website. The calculator can be found here: https://h-dev.co.uk/dyno-comparison/?v=7516fd43adaa

Using the provided DynoDynamics numbers with Horsham's conversion calculator, V1H's car is making the equivalent of 503whp on a Dynojet! This is right in-line with the power range we generally tune our in-house, stock-block 370Z's using the AAM Competition Twin Turbo System (for sake of reliability and longevity).

Although the twin turbo system is capable of producing MUCH more power, this area is generally considered the "sweet spot" on setups such as his. This 370Z is definitely going to be one heck of a street car! You're going to have a blast with it.

Out of curiosity, are your in-house setups with 503whp also only running 5-6psi?
