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?

Great news dude
Hope you have a safe run home take it easy snow forecast

I drove my car home on Thursday and OMG.. I cannot begin to describe the transformation. I do not recognize my Z! It's utter savage, especially considering I have been driving an Astra 1.4L for the past 4.5 months.
I drove off still in the wet, on a straight road in 4th as 60mph I tiped the gas pedal a bit and the rear broke momentarily loose only for the T/C to safe my ***. Later down the journey, while all roads fully dried up, on the motorway I pulled out of a 50mph zone in 3rd and again spun the rear wheels. A BMW M6 right behind me could barely keep up! :icon17:

I still am digesting what animal H-Dev bred in their shed, I totally love my ride, any more power would currently be not healthy for myself.

I severely need better rear tyres (305/30R20 Michelin Pilot Sport 4S), barring current lack of funds :p

Can't thank enough AAM, Torqen, H-Dev for the realization of my dreams, despite nearly 3 yrs in the making :tup:

Best wishes
René

Awesome go carefully dude
Well all meet up soon and you can show us how our superchargers need to be turbos :)
Merry Christmas glad your happy with it

Hey guys,

Just dropped off my car to the shop on Saturday for my AAM TT build, potentially the first RHD AAM kit in Australia to be fitted?

This will be some fun for the shop and the very first boosted 370Z in South Australia.

Made my purchase from AAM, Luis and Patrick have been awesome. the Kit is being installed as we speak and Dyno next week.

follow me on instagram for the build

Damm wish the shops down here could install the kit that quick.

Very short drive to grocery. Hardly an opportunity to stretch her legs but made a quick video anyways.

In case a streaming issue occurs for you, here the direct link.

made it into car magazine
 

Hi all, little highlight to share, my AAM 370Z-TT is now featuring in a current car magazine! I posted some evidence in my build thread :happydance:
https://www.350z-uk.com/topic/100623...omment-1785822

Very rare in europe: AAM Competition Stage II kit. We just finished the mapping and made a video for all Z fans: https://www.youtube.com/watch?v=8nC7IFhLdE4

700hp and 540ft-lbs on pump gas.

Cheers

Droooool
I need money so I can forge my block and also crack open my AAM kit

Nice powercurve..surprised by the quick spool of the aam stage2. Did you encounter any problems with the internal wastegates?

Just sent my car to AAM to get turbos installed can’t wait to see how it turns out.
