Z1 Motorsports: AAM TT Kit Installed & Evaluated 609rwhp Stock Block
 

Daaaayum! Nice work. I even turned down BIG's Big Pappa to listen to the video lol.

I wish my kit allowed me to use the Z1 CSC elimination kit. Congrats to the owner. Im jealous!

610whp on 9.5 psi?! that AAM kit is pretty serious :tup:

Looks good, is the owner on the forum will add them to the FI finished builds thread.

Great review and feedback John, thanks for taking the time to provide this community with some additional information.

And I will agree - the Shipping Hiccup was most interesting. I never would of thought that somebody would try to keep items that were shipped to them by accident... FEDex's Security team and the local police surely changed his mind on that.

If anybody has any questions on the TT system I would be more than happy to answer whatever John cannot.

Happy Driving!

That much hp on 9.5 psi is crazy! Congrats on the build :tup:

Nice job!!!

John - What Z1 clutch is used the full face or 6 puck? Also any hard start issues with 1000cc on pump gas?

The hot side of those EFR turbos is performing very well. To spool up so quickly while flowing so well to keep the boost pressure low is impressive technology.

Well done on the tuning... much smoother lines than I was able to do with mine.

Thanks for using our fuel system and mentioning it!

Sweet! Does AAM include instructions? I wonder if this can be a DIY :tup:

You will need to lower the motor for installation so your gonna need access to a lift.

Everytime I read one of these reviews, I regret that I did not wait to the AAM TT kit or the F.I kit :mad:

Great job, hats off to Z1 and AAM :tiphat:

The more I read about this kit the more I want it, I just wish a had a manual AWD sedan. Twins and Auto scare me. I know about the level 10 trans but :/.

That's a lot of power on a stock block. How long do you expect it to last at that power level??

:facepalm:

here we go...

What do you mean (here we go)? Stop being a drama queen and chill dude..:tup:

Nice numbers john and smart to hold back on the tq.. :tup:

^lolol

Suprised it made that much with a single exhaust. I picked up 40whp with a custom dual 3 inch from aam over my ark system.

Great looking kit. What were these hiccups mentioned? I'm thinking of going this route due to the EFR turbos.

Someone was trying to get this kit for free huh, lol. I live local to Z1 and Carroll County PD don't play those games, lol.

Kettle

I need my bank account to blow up asap

I think as long you don't drive like an idiot it will last for a while, and the tune is very important. I member reading something from CJ motorsports ( I think) that their 370z with 600 plus whp (stock block) has 40,000 miles and still running strong.

His car hasn't been making 600+ for that long. I believe he was pushing mid 500s for most of those miles before he turned the boost up

True statement. It was pushing around 580ish for most of those miles. Let's also not forget he was running E85 too which is apples and oranges against what a pump gas tune would do.

Back to the regular scheduled program...Nice build and tuning job John!

Cant wait to see long term like some of these other kits out there... Atleast if something happens down the road Im sure john will be ready to sell you a built motor...

I'm wondering how they were able to extract thatch more power out of 9.5 psi when the other kits on the market are around 12-13 psi at that power level. Does Aam flow that much more air on the intake side? I guess there's a couple different factors when asking about psi including exhaust and tuning. Did I answer my own question?

There are 3 typical ways to make more power per PSI.

-Colder Air
-Improving natural airflow through the entire system as a whole (often referred to as Volumetric Efficiency)
-Tuning

Tuning is sort of obvious. More efficient & optimized tuning will produce greater power output given the same quantity of air and fuel. Being on pump gas, I would take a guess that it is not tuned very aggressive.

Airflow is most likely where most of this is coming from. A turbo that flows better on the exhaust side will cause less restriction of airflow through the engine system as a whole, in the same fashion a better flowing exhaust system will; therefore lowering boost pressure at the same airflow. Airflow is airflow, boost is the measurement of how much the airflow through the engine is being restricted between the turbocharger compressors and the engine cylinders. If you increase airflow through the engine, such as a higher flowing exhaust (or higher flowing turbo hot-side), boost pressure will go lower even though the airflow (thus power) remain just as high. Although if you want to be technical, a wastegate is regulating boost pressure not airflow, so you would have to turn down the boost to keep the power the same after improving airflow through the engine.

Temperature is a small factor here, since lower boost means less heat generated through compression, translating to lower intake temps, denser air, greater power. So this is basically a compounding effect of a turbocharger that flows better on its hot side... I would guess making a rather minor contribution since we are only looking at a few psi difference.

Don't forget too we're talking about different dynos on different sides of the country with different conditions etc etc etc. As I have said before... Wait for a trap speed and then we'll see what this kit is made of...

:wtf2:

That dyno might read high. All the other cars Aam have built including mine are right around 550 depending on exhaust. I made 501whp with a 2.5 inch ark system. With a new custom 3 inch system from Aam I made about 540-550whp. And that was at the same psi

Are you using their Borg Warner EFR turbos?

While I agree that trap speed does speak of power to weight, dont you think track conditions such as air temp, elevation and baro pressure play a factor in the trap speed for that particular day and setup? Hell even powershifting will add 2-3 more mph, so unless its the same driver its not even comparable. That's why even in stock form, there are varying trap speed and 1/4 times across the country. I tend to trust "Dynojet" more than trap speed or any other dyno simply because the operator has no control over the input of variables. I have tested 3 dynojets on previous cars that I tuned and they all read within 2-3% with temps and baro pressures varying from summer to winter.

Well in a perfect world I would like to see turbo kits side by side in a 60 roll.

But a trap speed to me is more important than dyno numbers. I want my Z to trap 130+

As much as many people like to hate on roll racing... it really is the best way to isolate a cars power-to-weight for a race. Starting high enough, you can disregard nearly all of the massive variables contributed by tires, suspension, grip, driver experience, and more. Even the 1/4 mile is a tough judge unless the car gets a really clean pass... and good luck finding anyone with a high power 370z that is willing to say they are satisfied with their best 1/4 pass. Youre either wheel hopping for 200 feet, burning tires for 150, or banging the rev limiter in 4th 100 feet shy, assuming you didnt screw up the 1-2 shift that comes up in what feels like the first 12 feet with the all-motor 300hp style gearing.
