470 hp 370z greddy tt finished!!!
 

Jotech making final tuning adjustments today I and will have it tomorrow!! I will post pics and video if anyone interested. I was there last night when it was on dyno and it was amazing! Anyone in DFW area interested in seeing it stop by jotech and I will be around tomorrow after 5 to pick it up.

What PSI you running?
What type of dyno?
What are the torque numbers?

TT's are making more HP for sure.. seems torque is close from what im seeing.

450 hp @ 6.4 and 470 hp at 8.1
Dynojet I believe and will check on torque tomorrow I think it was close

nice! can't wait to see pics, dyno sheet and more!!!

:confused:
More than what? I am just curios about his numbers, only a few have done the greddy kit so far.

Good numbers, cannot wait to see some graphs. :tup:

Im sorry i meant they are making more than SC setups. I realize this is the norm for turbo vs SC, and expected from a higher cost kit. I was curious how close the SC kits were going to come, after advertised numbers were so close to those of the TT kits. You tube 370z TT dyno. A few have made 500+ on a dynojet.

In for the graph!

True, I will be on a dynojet hopefully this week with a SC kit and we will see how it goes, first runs were on a mustang dyno and it was all off. :(

working on new post now with video and pics

What engine management are you using?

I don't think it's really accurate to say that the TT's are currently making more than the SC's. Frankly from what I've seen both are making near identical numbers. A slight edge goes to the TT's but you're talking about maybe an addition 15whp. Considering that TT's cost much more and SC's are just coming out without any aggressive tunes or pulleys yet its to early to call it.

I believe that when the dust settles stage 1 TT's and SC's will come down to the driver, SC's might benefit from the flatter torque delivery. The limiting factor won't be the FI setup it will be the block. The stock block is said to safely be able to withstand 500whp, with is obtainable either way. The one clear advantage TT guys have is longetivity. When we start seeing built motors the TT's will really take off, until then it'll probably be dead even.

Seems about right on the numbers.

I've been pretty surprised at how low the numbers have been from TT setups...

Dyno Sheets!

:worthless:

:iagree:

I want to see a spec sheet that shows the stock block being able to handle 500 hp.

Well there's handling it, and then there's the question of motor life. I would imagine you are dramatically reducing the expected mileage to a rebuild.

As you increase the stress on mechanical components, you reduce their fatigue life dramatically. So highly stressed parts are going to fail alot sooner. If you keep the stress level low enough, those same components may last for an infinite amount of time. So when Nissan engineers design these components, they are shooting for x number of cycles to failure (maybe 300,000 miles at an average rpm of 3000 as a guess) at about 270hp max to the wheels. So if you double the max HP, you probably decrease cycles to failure at least 5-10 fold maybe more is my guess. But you'd have to know the actual increase in stress and the material types of each component to know for sure.

I'm pretty sure Forged said from their block inspection that they thought the engine could safely handle 500 whp.

No one's going to know how much power the engine can produce without breaking something until someone breaks something...

But completely tearing a block down and looking at the components can definitely give you a good idea of what you've got. These guys build engines. They should know what these things look like.

what does it look like? it's just a lump of metal. how can anyone tell by "looking" how durable an engine is?

Just in case you aren't being facetious. Those with many years of experience with building high horsepower applications can just look at that lump of metal and give you a good idea of the durability of said lump of metal.
I would imagine (because I am not one of those people) that you could tell by checking the thickness of the higher stress areas and where the block is braced or ribbed.
Take for instance the small block chevy, there are some blocks that have only two bolts on each main journal that holds the crankshaft in place. There are others that use four bolts on each main to hold the crank.
Which do you think would handle more power?

for our applications, Turbos will always outpower surperchargers.

and with the correct setup they will have near identical response.

Ay my Man, u got to post some vids. You reppin the DFW. Represent!

That is not a totally true statement, and which applications are you talking about so I know what your applying that statement too?

:iagree: who has that written on paper from Nissan?

Still no dyno sheet posted?

Contrary to popular belief there is a lot of stuff inside that "lump of metal."

This is absolutely true, but ultimately a limit isn't known until it's breached at least once.

I'd just be happy to know how meaty the OEM piston ringlands are... that's usually the first thing to break even with an otherwise good tune.

Yep. And it will take a few people breaking stuff to identify the true weakpoints of the motor.
