2.0T GT30R Dyno with over 357 horsepower and 298 ft lb of torque to the rear wheels

[Gadfly]

again, 357hp on a GT30R is emberassing.

and no, that IS NOT the stock turbo. it spooled waaay too slow and it screamed like burning babies in hell. the stock turbo WOULD NOT sound like that.

i can't believe someone would ACTUALLY say "i think it's the stock turbo".


carlos nice

Well the only pictures of the car show a stock turbo, and the stock exhaust manifold with all the IC pipes all fabbed up and installed.. Also any turbo can and will sound like that though an open intake, or and intake pipe with a cone filter stuck on the end of it.

The intake pipe in the pictures is very short, and just has an airfilter on it.. Hence the sound...

Spooled too slow? you kidding? you see that dyno sheet?? It hit damn near peak torque at 2000rpm..... GT30R on a 2.0L motor is not going to spool at 2000 rpm...


Again.. I think that is the stock turbo with the intake, exhaust, and FMIC just like in the pictures, on some race gas with the boost turned up and a mild tune.


Here.. take a look at this old vid of my supra... short intakes, cone filters.. = turbo noise...

again, you're not going to get that sound from a STOCK TURBO, but thanks for proving my point.

hold a stock turbo in your hand and then hold a GT30R in your hand. there is a SIGNIFICANT difference in the two. and at WOT the little tiny baby stock turbo, even with "filters" or "running open faced" will NOT sound like that car, dude c'mon, be serious.

Spooled too slow? you kidding? you see that dyno sheet?? It hit damn near peak torque at 2000rpm..... GT30R on a 2.0L motor is not going to spool at 2000 rpm...

dude, WHAT IN THE HELL are you talking about !?!? show me on that freakin dyno where the damn car made full tq at 2000RPMS

they started wide open throttling somewhere around 2500-2800RPMS and it didn't even hit full tq till about 4000RPMS. LOOK AT THE GRAPH !!!!! what freakin dyno are you looking at !?!?!?

nice car, but even yours spooled waaaay too slow. doesn't matter in Supras though cuz they are JDM HIGHWAY MACHINES.

First off... My supra is a road race car, not a highway machine. It sees road coarses on a regular basis.

I was refering to the dyno sheet on the screen in the video...

Honestly it did not sound impressive to me, and if that is a GT30, which again, the pictures clearly show a stock turbo, then he must be running like 8psi or something retarded.. 357 with a GT30 is pathetic.

 

[Redline]

357 really isn't that bad for a 2.0 liter 4 cylinder with the GT30R. If I put one on my Saturn, I would be running about that much power at 15 or so psi.

 

[bkprodigy]

i DEFINATELY am NOT impressed with the numbers. jeeezuz people, it has a freakin GT30R in it and it ONLY makes 357hp !?!?!?

that is terrible. my weak 20G turbo makes 356AWHP and i got an 2005 STi. either that thing is tuned terrible or the engine just can't handle any more power. not sure what it is, but my eyes are opened to whatever anyone suggests.


carlos nice

Without knowing the state of the tune, it's too early to state your impression.
For all we know, it could have an extremely conservative tune with no timing/boost at all.

FYI, 356awhp on 20G turbo is not that impressive either.
People are making 420awhp/450awtq on 16G on evos left and right.

 

[bkprodigy]

Do you have the gear ratios and final drive ratios? Rear end gearing? if so you can calculate top speed.

If a GT35R only makes 450hp then something is very wrong.

I will stick to my Bullseye Performance Turbos based off Borg Warner turbos.. Make more power and spool fast than the Garrets / Percision units. I am guessing with a BEP360 (60mm) i will be able to put down 500-550.

Keep in mind this is a 2.0L motor. 450whp sounds about right on 2.0L if the fuel of choice is 93octane.

If it's making that number with race gas however, something def. is wrong.

Well Carlos, it's nice to see you haven't gotten any smarter from your days with the Neon.
Obviously if this car uses a GT30r, it is in the stock housings, which is completely feasible in today's turner market. I can't say if it is for sure either way, becuase I don't have the compressor in front of me to mic it.
Secondly, if this power is so weak, then so is your car since a gt30r and a 20g have similar choke flow ratings Perosnally, I don't think you can call it weak becasue no one knows how much boost he is running. Since it appears to be using the stock housings, I doubt there have been any other efforts to boost VE, so it's not going to make a ton more power at the same boost levels without some decent boost in it. However, since no method of tuning is mentioned, I am willing to be it has stockish fuel and air metering, which means it will likely be running 20 ish psi. It's only a 2.0l motor folks.
Given these observations, I think this power is pretty good.

 

[GraysonHyundai]

Here is a dumb question..I am from the Subaru land of engines.

With the GT30 being said to be used on this 2.0, how will internals (not to mention the transmission) hold up to this type of power.

In Subaru land, a stock WRX engine will hold ok power, but the transmission on 2007 and older WRX's wont take much more than 300awhp before deciding to grenade.

I know with most Subaru's going to a rotated 35r, most will do it right and do internal building.

The STI tranny will hold LOTS of power so that isnt really a weak point on the STI's to worry about but, how heavy duty is the coupe's 6 speed to hold a lot more of power once big kits (and more details) come on how to mod the coupe? I have not seen much said about how the car can handle a lot more power...only threads on how people think they can make a lot more power.

 

[grant]

you gotta keep a few things in mind with the subies (coming from a 400WHP 06 Sti) that this car isn't gonna hook-up like a AWD car so there will be less shock on the drive train at launch. . and the stock WRX tranny is a bit like "glass". . not to often do you hear about many cars shearing pretty much any gear like WRX's do with 350WHP while cruising ! lol

I think only time will tell about the tranny. . and hope that I'm not the first to find out!

 

[bluetwo]

This thread rocks anyway.... the pictures on the first page were entertaining enough for now...... for me anyway. Ha ha......

And who really wants to be the first person to find out what the engine or tranny will tolerate? It's just a matter of time before people figure it out on their own cars or units, whatever they wanna call it. I hope it's tuning companies who get to use other peoples money experimenting.

I see it IS a TD04 turbo though.... great for instant spool up torque and reliability.... not so great for the big power hungry guys out there. How would it be if the Lambda turned out to be a much better option than the Theta?

i'm only on 20psi with a stock sized MAF. that turbo is not even at it's full capacity. should be running 24-26psi. i'm too lazy to go get a big MAF and then go out and get retuned because i'm trying to get rid of the damn thing.

i'll tell you this, from one STi owner to another, if you're comparing your current STi tranny to anything out there right now, you're gonna get let down.

you can throw an Sti tranny into the sun, get it back and bolt it back up and it will run perfect.

i have a feeling the GC tranny will be as weak as an EVO's tranny.

carlos nice

 

[bluetwo]

Yeah.... you always hear about how even the 9 second STi drag guys love their 6 speed transmissions so much they swear by them. I mean these guys break axles all the time but the tranny stays strong.

 

[kortERHorse_281]

not only the tranny, but the engine as well.

i heard the "3-second delay in power" feature is going to ultimately make or break this car.

how retarded is Hyuandai for doing this !?!? if you don't know what i'm talking about just read below

Where the BS Stops
At the test track the 2010 Hyundai Genesis proves itself a worthy entry into the sport coupe segment by giving the pricier Infiniti a run in several categories. First, the Genesis tips the scales at just 3,488 pounds — 221 pounds lighter than the G37. Porkiness has long been a valid gripe about any car built on Nissan's FM platform and the G is no exception.

But being lightweight didn't help the Genesis coupe accelerate as quickly as we had hoped. The Genesis hit 60 mph from a standstill in 6.4 seconds (6.1 seconds with 1 foot of rollout like on a drag strip) and went through the traps at the quarter-mile mark in 14.5 seconds at 97.9 mph. That's considerably slower than the G37's 5.7-second run to 60 mph (5.4 seconds with 1 foot of rollout like on a drag strip) and its quarter-mile performance of 13.9 seconds at 101.4 mph.

Accelerating the Genesis quickly can be tricky because of a drivetrain protection feature built into its engine calibration. Shift the Genesis coupe aggressively at redline and you'll occasionally experience a power cut in your target gear which lasts 3 seconds.

The problem is exacerbated by the car's tachometer, which doesn't keep up with the engine speed in the first few gears, so it's too easy to run the engine to its 6,800-rpm maximum speed (redline is 6,500 rpm). Hyundai says the drivetrain protection is triggered at 6,800 rpm, but once it intervened, we experienced a power reduction in the next gear at much lower engine speeds. Run this V6 to the rev limiter in any given gear and it will hang there comfortably. But if you shift hard and quickly at the indicated redline, you'll occasionally be punished with that cut in power.

Hyundai is considering a new calibration, but there are cars going on sale that incorporate this 3-second power intervention, a feature that can punish drivers at engine speeds well below redline. Some people won't notice it, but to others it could be a deal breaker in the purchase of a Genesis 3.8 coupe.

[Cruiserdude]

I had read that about the V6 models, but I haven't seen anything yet to suggest that the 2.0T will suffer from the same problem. I would think that Hyundai would realize how big of a deal that could be, and have done their best to address it. The simplest way would be to recalibrate the rev limiter to say, 7000rpm, assuming the stock valvetrain can handle that. But the real issue here is the tach lag, if the rev limiter can tell when the engine hits 6800rpm, why can't the tachometer? They really need to find a way to make the tach keep up with the engine, that's quite a big deal, actually...

 

[John]

Most cars are the same way, why do you think ricers install 7" tachs on their dash? The thing I don't get is why make a car that has 300hp if you're scared the transmission can't handle the power? It's like a boxer eating donuts for a month to move up a weight class and forgetting to work out. Strangely the 2.0 and the 3.8 have different transmissions so this may not be the same case for both but that also leads me to believe that the 2.0 will have a weaker tranny to save money

 

[kortERHorse_281]

in the long run, i think the 2.0T will not be worth the time and money to keep it running if you decide to mod it.

ams and buschur dont seem to think the cars are a waste of time. but hey what do they know. you say its weak numbers for the turbo before you know how the tune is or how mild the stock cams are and plus its more or less the same power your making (differnt dyno's same dyno it might be more then you ). maybe they just bolted it up to see what they could easily run.
maybe the car will great maybe it will be a pos no one really knows. i know new things are scary but it will be ok. im sure bushur and ams will push the motor to its limits then find a way to push it further.

but hey in the end of the day if i had to between an sti and 2.0t GC .

new sti know for running lean in full boost and popping motors since 07 and worse in the 09's or the unknown GC i would have to take the gc at least i dont know im scewed off the bat but maybe the subi will give little red wagons to pull around your smooth shifting tranny when the motor pops.
