WOW

(jaw is dropped)

Thanks man!

In our experience with final drives, we actually go the opposite direction. A lot of Manual Trans TT 350Z guys will install automatic 350Z rears in their cars to lower the final drive from a 3.5 to a 3.2. With the lower ratio, the cars actually stay in boost longer, for a higher top end. The N/A road race/auto x 350Z customers usually step up to a 3.9 from Nismo, or Central 20 or whatever. Road race and auto x competition cars benefit from shorter gears, to get from apex to apex quicker. Street turbo Z owners generally like the longer gears better, because the added power from the turbochargers helps the car to REALLY get moving when you are on an open road.

We had great success working with the COBB AP (and COBB directly) with this 370ZTT. With the MAFS, the car drives flawlessly. The cobb software can drop the timing curve, but the ECU is very smart. So timing changes must be well matched - if the curve that you've put in is too aggressive, at points the ECU may adjust to be what is optimal for the vehicle. We tested extensively and experienced no knock, no limp modes, no codes (HFCs work wonders) and the car simply runs perfect (and moves out!)

I am not sure about the G37 however as it is different and we have not yet (but soon) tuned a twin turbo g37 with the COBB. We hard wired f-cons in the past.

The COBB AP really is a marvelous tool.

well that is just marvelous to hear, I knew cobb would finally get their together one day. now what version of the tuner software do you have? because unfortunately the version I have (1.7.3.2-11265 Build Date Sep 3 2009) isnt doing jack! I have tried everything you can think of to manipulate all ignition tables and the car shows no responce what so ever.

I have some experience with AEM, PowerFC, haltech, big stuff3, Hondata, Motec and find The cobb the trickiest to use because it does nothing.

so you must be working some magic! that i dont know about.

Good job. I'm really digging that exhaust btw.

what a beautifully designed kit, im impressed.

wow, now that is a beast!

wow....very nice!!

does a TT kit like this pass state and emissions?

This may just be in my very near future.
Very nice job AAM team!
:tup:

What’s the projected ¼ mile time……….0 to 60?

Ill take a guess.... :eek: 11.5 ??!! on quarter depending on hook up, 0-60 no idea, I would imagine on the street this thing tears up rear tires:icon17:

0-60 mph Calculator - 060calculator.com

0-60 about 3.4 sec.....if you can get a hook-up :D

Lets take some constants here:
hp: 500whp w/ 18% drivetrain loss gives us 610fhp
weight: 3300lbs
Transmission: Manual

0-60: *0-60 mph Calculator - 060calculator.com*
2.9653502733333146 seconds @ 610fhp

3.4422774631379625 seconds @ 500fhp


1/4 Mile:
-Your ET / MPH computed from your vehicle weight of 3300 pounds and HP of 500 is 10.93 seconds and MPH of 122.62 MPH.

-Your ET / MPH computed from your vehicle weight of 3300 pounds and HP of 610 is 10.23 seconds and MPH of 131.03 MPH.

i think it will run high 11s. traction...launch its all going to make a huge difference

Bullitt, when is your car going under the knife?

well everything starts shipping out this week and I get my car back with a motor today soo if everything goes as planned I should start at the first of the year (1st week of Jan) :D or sooner :excited:

Very nice.............I am in love!!!!!!

AAM can you please PM me on details on costs to design a kit like this for my z? im very impressed!

i love the hp. but im very dissapointed at the lack of torque it has.

my 300zx will be putting down more torque on the stock turbos with my mods.

Prolly due to the WG only boost, with a BCS of some sort they would pull in gobs of TRQ

hahahahaha... no

In most N/A to Turbo cases, you're right. But the newer Nissans respond a bit differently to TT installs.

As far as emissions goes, our basic Twin Turbo Kit installs don't prompt any check engine lights from the ECU. For emissions testing, if you car doesn't have any ECU error codes, generally speaking, you're A OK. So emissions shouldn't be much of a problem. :tup:

State inspection, however, varies from state to state. Depending on the state, if they check underneath your car to see if you have cats on the car, they'll still see the turbo catted downpipes that look like cats, so you should still be good. But we can't guarantee that.

in GA as long as there are zero codes u are good to go :tup:

It seems odd to me to spend that kinda money on a turbo kit and go with spring-regulated boost. Would love to see what an EBC would do.

Or go to a friendly mod dealer. :tiphat:

Lou, if you were here in GA I sooo would be having you guys do my work and maintenance!!!

subscribing to this goodness!

Need TT that will pass inspection in CA! LOL

any video yet?

Manual boost controllers - E85 and let the algorythms of the 'advanced' Nissan ECU punch the timing, optimise the VE etc to get some serious neck braking sensations;)

I posted one on the second page, but for some reason it was having some trouble embedding in the forum. I re-up'ed the video, and added it to page 1!

Shipping a turbo kit without any type of cabin mounted boost control is actually a smart way to go about it. There are dozens of selections for electronic boost controllers and every person will have their preference.

Did you guys check the coolant pressure? Im intrested however im curious how the head studs, input/out put shafts, motor internals (push rods, pistons, fuel spray pattern) holding up?

:crying:Where's my Z :crying:

I wasn't talking about the kit, I was talking about the finished car.

Hopefully I can cover everything for you with my answer here; the coolant pressure is unaffected by Twin Turbo install, we maintained healthy operating temps for the engine, and at this point, saw no need to upgrade the radiator or any other coolant accessories on the motor. We did however, install an external AAM Comp Oil Cooler on the car, to keep the engine oil temps down on hot days or during track use.

The factory VQ37VVEL engine is a very stout, adept motor from the factory, capable of easily supporting over 500rwhp. At these conservative boost levels, there really isn't much concern about lifting heads, so factory head bolts, head gasket, etc. were left untouched. We didn't even go internal much at all really; just a basic Twin Turbo Install. The customer wanted a car that would perform well on the track, but more importantly, he wanted the car to look and feel like factory on the street. :tup:

In addition, the 370Z engine is actually not a push-rod type engine, it is a traditional Dual Overhead Cam. The factory pistons and connecting rods will be strong enough to support the cars power output at the current boost level settings, thus internal engine upgrades will not be necessary until the customer requests higher power output and higher boost levels.

Thank you i appreciate the answer.

wh00pass !

Lou,

Are you saying you still haven't seen your car? You dropped it off mid-August! That 4-6 week turn-around is now 20 and growing... :confused:
