I think, if I read correctly, he means on the single 35R turbo. That more than 550whp is outside of the turbo's efficiency range and is dangerous.

 

If the turbo can make 650whp then 550whp is not out of the turbo's efficiency

 

I'm guessing this is where race gas comes into play

 

Thank you. It's really not that confusing.

 

i give up... i'm just going to shoot for the moon and report back.

 

^ +1

LOL
SO WAIT... all this fixation/.insinuaton/egging the thread is because some people are insinuating the kit is not proved, inneficient and it should not be advertised to 650whp, when those numbers were indeed achieved with a dyno sheets, videos, and the car was track tested with 1/4 mile times??? lololol in what world is this community living in?? its just like the reason why injected doesnt ned to prove their 1000whp+ power levels: because of this:9.34@ 145 mph...the semantics game here to try to egg are ridiculus.

Seriously, the dynamics(VE) of pump/race gas on a single turbo are completely different from twins....
the Op feels mislead because he coudlnt reach 500hp when hal already did reach 453whp DD = ~500+whp DJ? ...so "dont see why +500whp isn't possible on pump."....well, me either ....

the insinuations to Tn kit have also been laughable, considering that on the same dyno as the op as you can see the efficiency numbers and raising of boost were a true disaster
"3 psi gain in boost resulted in more power earlier, but a significant drop off in top-end power"

PharmD u need to realize this fact as its not an apples comparison, otherwise it becomes a semantics game only which should be reserved for strawmans...do you seriously expect turbos to have the same efficiency range and bheaviour on any fuel grade?
As storm said, its pretty simple really... and the piping is flowing well.... considering that the same one was used on the run with the 76S...
if you compare hals gt42r , with powerlabs 76S u see exactly what you would expect from this turbos on well designed/flowing piping...
So i mean its not like you need to "give up", just understand the flip side of the deal that doesnt inolve semantics game....
obviously i guess it was pretty clear to me with the thread that the 650whp numbers were on race gas as i think it was for many others... some i guess felt that it was misleading not to say it... sounds like a streach... but anyways, its now noted...

 

Oh no dude, I'm not insinuating anything about the kit

I like the kit

Ironically, I was going to mention the TN kit. I've seen first hand one being tuned where it was just blowing hot air.

And 500whp is tough a DD, that's damn near 600whp on a DJ.

 

^^ lol...i jsut realized i had a post from you quoted there.. my post wast directed to you... greg haha....i didnt & woudnt think anything like that coming from you anywyas...

Edit. actully i think i originally got it there cause i wanted to say +1 ...

 

Good points. I was worry about the possibility of the the turbo a not being a genuine Garrett so the turbo was checked serveral months ago to confirm it's origins. It is a true Garrett product but I will check the stamp on the turbine housing to confirm if it is the .82AR housing. I am very aware of the business ethics of JT but I will state that my dealings with Jeremy were truthful and professional I had no issues of the advise, products, install or tuning. I had Hal retune the Haltech because of idle and gas mileage issues. If you have an Haltech, Hal is the guy too see in my opinion.

 

I understand to points that you are trying to make about the same piping of the kit but you are right about comparing apples to oranges so posting dynos on the G37r and 76 only add more confusion. I am discussing the power potential of the gt35r kit so please limit the dynos to that particular kit. The questions at hand is the actual power potental the the gt35r kit. Thank you.

 

The 453 whp dyno shows that it can make power on high compression stock engine but these are unsafe levels of power due to detonation issues which will occur. I have already stated on several occasions that the kit is excellent on the stock block setup. I also will agree that the kit on a stock build is a superior design over the Turbonetic's kit. You guys keep speaking of semantics but this exactly what you are using in your advertising and it is the complete basis of your whole defense. 1. Race pump to make the power, 2. Power levels on the stock blocks, 3. Unsafe boost levels on the built block.

Since you like to make bold statements to sell this product I will make one for myself. I will have the car dyno'd with race gas and it will not make anymore effective power.

 

I dunno.

90% of the dynos you see of gt3582s on other platforms are around 400-450hp.
Thats why I wasnt surprised when he said thats what they got on pump gas.

The issue still remains on why the AITs are so high. Thats why i asked where his sensor was, but never got a response. If he brought his AITs down to 'normal' levels, more power could be made safely.

But obviously with high AITs, that brings about knock much sooner. And no tuner in their right mind would keep pushing a car into knock, esp since I am not sure if Hal tunes the active knock control.

Running a max power curve vs running something stable on the street are 2 different animals. You will never get PL to disclose what the engine vitals were doing during that pull. With race gas you can often 'ignore' high AITs, etc, but you can bet that it was up there.

Although... S2000s are freaks lol

I'll still say that reaching 500whp on a DD on pump is no easy task...

 

OP in your first post you said more power isn't posible without changing the turbo and building custom piping.
The only reason why i mention my gt37r and maybe the reason why Gorge posted those 76 dynos.

I'd leave the piping as is

 

so how does an evo put out 600+ awhp.. on a 35r pump.... and a 350z with a bigger motor, cant?. I still think that something is wrong with the install or something small HOPEFULLY..

 

you can't base the gt35r on a small displacement platform dyno like that.

At those power levels with that turbo you are going to run into exhaust restriction on a larger displacement engine. The turbo exhaust housing will be the restriction in exhaust gas flow, like stated many times in this thread a restriction in flow limits numbers and causes high IAT's.

Put a gt35r on a 6.0L engine and watch how that thing won't make near the power it will on a small displacement because it will choke the exhaust like crazy.

You need to compare it to a similar displacement engine, so maybe a 2jz. Like rich said, those are going to be sub 500hp when you start looking.

ALSO, you have to account for variances in dynos. 536 isn't destroying the ~500hp dynojet for this car's dyno.

 

it's about exhaust flow vas. just like i posted. You can't put a turbo that restricts exhaust on a big enigne and expect to put up huge numbers.

That's just the same as putting a huge 88mm turbo on a 2.0L engine. Gonna take forever to spool since that small engine isn't putting out near the exhaust that a 6.0L would.

Just as a reference. My buddies 6.3L has a 76mm turbo. he's mid-teens on psi and i think maxed the turbo out but stuck at low 600's. You put a t76 on our 3.5L and it will do well over 600's. His is being choked by the turbo exhaust housing. He's swapping a pt88 (88mm) next week.

 

Gotcha.

 

Every dyno reads differently. 465 at 13 psi may be great for that dyno, who knows. Are you saying that you cannot make any more than 13-14 psi?? What WG spring is in the gate?

 

gotcha!
