Forged Performance: 370Z Greddy TT Complete Package Results
 

We recently completed one of our local customer's beautiful Nismo 370Z. It came to use bone stock, and left with a very clean and powerful TT package. These are the basic, yet safe elements of a good TT setup. For the time-being, we are running just wastegate pressure of 5psi but down the road I'm sure he'll be installing a boost controller, clutch/flywheel and shooting for more power. The car starts, idles, and runs just like OEM, but with the addition of 150whp at just 5psi boost pressure. We've made well over 500whp with this kit on the stock block on our low reading Dyno Dynamics dyno. In and out in 7 days start to finish.

The acceleration and spool up is fast and seamless....so much in fact that I got a ticket doing some road testing with it...ops. :)

Video of Dyno Tuning:

Wow nice - that tq looks pretty awesome! Very drivable i bet :)

throw some Volks on that bad boy!...congrats on the build btw..

Very Nice! PM sent.

Gorgeous! Great job! :tiphat:

WOW nice build sharif looks like a A++ job. Not to bring up old stuff but with some of the previous build issues this particular one shows how professional your techs are. I mean that as a comment so please don't flame me.

Sweet! I'm not all THAT far from Forged Performance, so they are probably who i'll use whichever route I choose for FI.

Looking good!
Looks like it makes great power for DDing.

Great numbers on your heartbreak dyno! Very impressed

Didnt this car only make 394RWHP @ Znationals? Sounds like a DynoJet is the real "Low Reading Dyno"

Many factors can affect dyno numbers. That's why I don't make specific claims about how a dyno will read. From our experience, our Dyno reads lower than most. The other 3 Forged cars we dynoed (350Z HR TT, 350Z TT, 350Z TT) all put down higher numbers than our Dyno Dynamics. So your guess is as good as mine.

Couldnt that be the race gas in those cars? it was obvious that alexs car had a thrown together tune for the RG and rumor was that on race the night prior it made 700+. I dont blame you though nothings better than showing up at a competitors shop and taking there trophies

nice work buddy. hurry up and sponsor me now. :p

I have to agree whith forged on this one. Dyno's vary way to much, from the weather, how they are strapped down, and how they are calibrated. Two companys can have the same dyno and both will read different. The first thing everyone told me when I bought my kit was to not get wrapped up in the number game, but to use the dyno more as a tool of how the car is running and a estimation of hp gained by running a base line before any modifications then after when modifications are complete

Alex's car was tuned to perfection the night before with race fuel and made sub 600whp on our dyno dynamics. Unfortunately, the spark plugs gave us all they had and misfired during the first dyno pull at Z1. We quickly pulled the plugs and they were worn out. Fresh set of plugs, and back and business. I made no changes to his tune from the night before and Alex did 600whp+

The second 600whp+ we had was running e85 and I tuned it 3 weeks prior. I was actually a little more concerned about that car, as the customer had driven in from Missiouri to pick up his car. Little did I know he'd end up winning the dyno contest. :) The third car I spoke of was a stock block HR with GTM TT kit. It made 430whp (might be off by a few horses as I cant recall the exact number...390whp on our Dyno Dynamics about 6 months prior).

Z1 has brought their car to the Forged Dyno Day as well, and won....good friendly competition makes us all better. Good clean fun. We support many of their events such as ZNationals and send 300zx customers their way...so I consider them just as much partners and competitors.

At the end of the day the dyno is a tuning tool, and not a highly repeatable measuring device from session to session. I'll refrain from making anymore comments about our dyno numbers in comparison to other dynos. :)

Looks good!

This car is a blast to ride in! Great build!

Do you Dyno in 4th gear?

yes, we always dyno in 4th :)

I wanted to thank all of the Forged Performance team on doing this great build. The team did a great job and the quality of the TT kit is awesome. When I stepped through the doors of Forged Performance, I did not intend on going the TT route but Sharif talked me in to it.
Z Nationals was coming near and Sharif told me they would get the build done before Z Nationals and they did. It didn't take the team long to do the install. They got my car in and out in 7 days. Now thats a quick install :)
This build came out great, the TT kit fit like oem, and they had no problems at all. I have no problems at all runs like oem and the start-up is great. I am amazed at how much power it is pushing with only 5psi. In the future, i plan on getting boost controller and new clutch and flywheel for some more power.

Why? Aren't you supposed to dyno in the gear that is closest to a 1:1 ratio but not into overdrive. The 5th gear in the 6 speed is 1.00.

Numbers look good for 5psi. Blue couplers, not my style, but congrats on the build!

congrats and nice set up.

The 1:1 ratio needs to used on intertia dynos such as the DynoJet. On Load Based Dynos like the Dyno Dynamics and Mustang, the gear choice does not affect peak power so most of us 4th gear to keep the roller speeds down. We've done many 4th and 5th gear tests and the peak numbers are the same. Hope that helps.

Oh ok, I didn't know there was a difference in that respect.

Do you have to input that information into the dyno for it to make the right calculations?

I've always dyno'd my 5AT in 3rd gear on DJ's :/

That's definitely a nice gain for 5 PSI. Do you guys have the base dyno?

Bone stock the car made 282whp this past summer at the Forged Performance dyno day.

Yup..thanks! Rogue's Nismo made about 270whp as well. The Nismos have all dynoed about 10-20whp higher than the regular 370Z which suprised me.

So...how did you get a nice looking curve? I thought everyone had trouble tuning these and it resulted in some wavy lines past the 6K mark or so? Is this a problem of the past?

Correct. Lots of 5.0 GT owners were dynoing in 4th and making near 400whp. They then got a bunch of them to properly dyno in 5th and the average was more like 360whp. It matters.

Tuning out the top just takes time and each Z will all be different based on the mods done.

Yes and no, it matters on what type of dyno you are running the car on.

Why was Z1 turning out such choppy tunes previously? Just didn't take the time, or has there been more advancement in understanding the PCM as of late?

Z1 has been doing automatics from what I saw and Uprev recently found some more automatic tuning abilities, not saying it will help with the power curve being smoother.
Also, companies can 'smooth' the curve when viewed on the screen especially when done.

Not thread jacking. But we try to show people what we see. The last car had boost fluctuation. I spend a lot of time on the dyno.

Not saying anything bad about you guys.
I have been to almost all import shops where I live and used their dyno for one reason or another, it is interesting what some do to 'adjust' the results.

Very nice numbers guys!

Awesome build:tiphat:

Wish I'd known the turn around time was 7 days instead of the 2-3 weeks that I was quoted. I was only in the US for a month, and wanted to actually have some fun with the car before I headed back overseas. Anyways the bolt-on's attracted enough unwanted attention so I guess it was for the best. Congrats on a clean build, but Im sure it will look even cleaner in black. :happydance:
