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

[Sal Collaziano]

I just sent this member of bkmania an invite to join here. I hope he signs up soon.. It has an aftermarket intake/exhaust system and a bigger snail Garret GT30R. I'm not sure how much boost we're talking about... Dyno video:

It's probably got a new manifold and down-pipe.. Right?

edit: It looks like the image above has been removed.

357 horsepower to the wheels?

If there's a 15% loss from the transmission and other parts between the engine and the wheels, that's 420 horsepower at the engine.

For a modern sporty car, that's respectable.

For a modern sporty car that costs maybe $22,000 with maybe $4,000 in mods, that's fabulous. (I'm taking a wild guess at the cost of the Genesis coupe turbo and the upgrade kit.)

 

[Sal Collaziano]

I agree! Except I think 420 horsepower for a modern sporty car is more than respectable!

The exhaust system is a work of art!! The tips are staggered in length and diameter just like the custom system installed on a 4.6 for the SEMA show. I wonder if they will become available after market for us?

If there are enough takers, somebody will make them.. Find more people, send them here and get them to say so.

personally don't like that exhaust...while it looks pretty good, there is no reason for there to be actually 2 pipes runing the majority of the way back. actually kind of silly for a i4 turbo...if you really want dual exhausts, a y pipe split is more than enough.

got confirmation that we will be working on a dual and single. *cough cough* will have something special with those exhausts *cough cough*

I agree, actually. It's beautiful to look at, but seems hardly functional...or at least, like it'd hurt performance. I LOVE the dual exhaust look, but I'd prefer it be like a 90/10 split. IE. 90% out the left pipe with a little to the right.

Well that turbo still has the Hyundai logo cast on to the front of it, and given it's location and unusual castings (that looks like the factory BOV is cast into the compressor cover?), I am pretty sure that it is the stock turbo, and that is def. the stock manifold. It looks like the only thing done in those pictures is an FMIC kit, and filter added in place of the factory airbox.

The HKS manifold allows a top mounted turbo, which is much cleaner, and provides a lot more room for larger turbos.

357 to the wheels is a nice start... but hardly enough.... Most modified Evo's and WRX's push well over 400rwhp, and anything domestic will run well over 450rwhp with just simple bolt-ons. In order to hang on the streets you will need to push at least 500rwhp out of the Gensis Coupe (Should be about 450 ft/lbs). I hope the stock internals are up for it.. I guess I will find out soon enough...

Also.. when it comes to exhausts, Turbo charged cars are not nearly as sensitive as N/A cars. All that really matters is the pressure drop behind the turbine wheel... So there is no point in anything fancy, or expensive. Just a piece of pipe the same size or larger than the turbine housing outlet is all that is required. It will not make any performance diffrence if it is dual exit, single exit, y'd, or dual pipe the length of the car.. As long at the diameter is there and the pressure drop is maintained.

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.

don't get too upset, if the car in the pictures is the same as the car on the dyno, then that is not a GT30R, it is the stock turbo. (Given the clearance from the compressor cover to the rail, I would say that you can not fit a GT30R on the stock manifold anyway.)

From the pictures it looks like in order to put a much larger turbo on there you will have to convert to the HKS style top mount manifold.

well, here's the video.

NOT impressed at all by the weak numbers. and i HIGHLY DOUBT that the stocker is gonna produce anything over 260hp - it's a TD04, very very small.

If the car has the same setup in the video as in the pictures than the numbers make a ton of sense. That turbo is going to lose a ton up top... especially torque. I think everyone gets their jollies off on dyno queens with high numbers. My buddies KA-T 240 has the flattest torque curve and makes peak power lower than most, I think his last run was 395ish/410ish and my friend with a big turbo 405/460 Sti can't keep up because guess what, he makes his power 10% of the time. If you guys are buying a genesis coupe to make a straight line car, please go buy a Camaro, this is going to be the new SRT-4 I guess

 

[Gadfly]

He certainly claims it is a GT30R, but that turbo in the pictures is the stock turbo.. so either he reworked the car after those pictures were taken, or those are just stock turbo numbers.

Who knows.. but something doesn't add up.

Maybe he put a GT30R wheel in a stock housing? You are right, something doesn't seem to add up. If he was maxing out the stock TD04, those numbers would likely be flipped, with more torque than hp since the little snail would hit hard then run out of flow at the top end.

Sickkkkkkk

I was somewhat wondering what kind of power it would make with a GT35R and some more modifications 450ish? And, what kind of top speed is possible with gearing upgrades.

 

[Gadfly]

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.

 

[kortERHorse_281]

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".

Again, that could be at 6psi. No one knows, they could just be breaking in the motor still. But I guess we'll just assume that because we saw the video that this was the final tune and it was tuned to its fullest potential. Ignorance is bliss I suppose but that would also explain the weak torque numbers if they put a nice wide downpipe and exhaust on it and its being cut off early. Whatever though, I guess not everyone sees this happen everytime a new turbo car comes out
