Oh the joy of modifying cars. You never know what issue will pop up. Looks like you had a good fix, which is nice.

:iagree:

Not to be rude or anything but that's a lot of money spent for 415WHP at 8 psi. You sure there's nothing wrong? My GT-R turbos made 460 whp at just under 9 PSI (wastegate pressure so its 7 PSI at redline) on 93 octane. Seems like your tune might be off?

There may be a number of reasons. I haven’t seen the dyno plot yet, only been told 500 bhp which I then naively converted to 415 whp under assumption of 17% tranny loss. I have NOT been given the actual whp yet. Also, our dynos may differ, as well as, correction factors. I have yet to see which standard was applied
I also run cat’ed downpipes.

The build is complete! I am probably going to collect my Z tomorrow or Thursday.:driving:
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) :tup:

Great numbers!

Great Work!

Can't wait now, Mine is going in January 6th!

To be honest man there is something wrong with your tuner or build....I just completed mine in Korea and got 542 whp with my AAM kit...You should easily be in the 500whp at the very least high 480+ depending on exhaust downpipe and what not....I would honestly get another opinion on you tune....you sure they are not holding some information out from you? Did you go with the small boost actuators for your turbos? honestly there is really no reason why you should be running that low on boost...just my opinion

All the best for ur build shadow!

Lol. I wouldn't be too worried about numbers man. As long as you enjoy it, that's all that matters

is he really enjoying it when that is what most superchargers are pushing? i honestly would not be happy with those numbers coming from a TT setup

Please show me a S/C pushing 400+ ftlb from 2800 rpm up. Else I’m just gonna ignore your comment and enjoy my collection drive today

of course no SC is going to pull 400+ at 2800...there are SC pulling over 400+ on this forum...not trying to piss you off on the build...but I just wouldnt be happy with those numbers is all...but than again you are running pretty low boost.....

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?
