350 seems an awful small gain compared to what the 2.0 can make with GDI...

 

350 is about where it should be, using basic math puts the 3.8L GDI at ~345-355 crank hp based on the gain the 3.3L GDI V6 got (260ish to 290 something after GDI). Pretty much any turbo engine is gonna get a higher increase from adding GDI because of better efficiency.

 

Forgive the newb-ness, but would this replace the stock injectors? or a totally different engine design?


EDIT: looked it up on wiki, looks like a totally different engine!

 

Just the fuel system setup.

 

I would say 370-380.

This article appears to say 5.0L = 400 hp, when Hyundai stated 430 hp, so going with a 20hp lower and 30hp upper range to add on the 350 range. Then again the 2.4L GDI seems to be right on.

My translator can't translate GIF's...cause it's a pic.

 

yep...380 would be nice as hell..3.8L pushing 380bhp is very good. 100bhp/liter.
If the 3.8 had 380 and was sold for 28k(R-spec) I would honestly sh*t bricks..

 

I think it's time to start saving for a V6 R-spec for myself..28k for a V6 pushing 380bhp makes me all giddy inside.
I/H/E w/ cams probably making 380rwhp..****ing nuts.

 

it's not technically written,(he speculates a lot of numbers and designs) he assumes the 3.8 GDI with a turbo will produce 450HP because the Porsche 3.8 Turbo produces 500HP

At the end, he adds "All engines will be produced within 3 years" He also states that one or two of these engine descriptions may be different from actual designs.

Too lazy to read, back to my paper for now. Will post full translation after my night class...

 

From what I've read, GDI will give at best, ~20% increase in power, when only changing the fuel system, obviously changing other stuff can net better gains. The 3.3L Lambda prototype GDI engine got a ~14% increase in power. The Theta II also got ~14% increase in power when GDI was added (went from 175hp to 198hp after GDI).

306*1.14=348.8

It's pretty much absurd to think it's going to be getting much more than a ~14% increase in power given Hyundai's current history.

 

depends, people have proven 300whp with I/H/E. If Hyundai felt like putting a less restrictive intake it might touch 380 with proper tuning.

 

Show me one dyno of I/H/E V6 making 300whp and I'll buy it. The only V6 to hit or break 300whp so far that I've seen is SFRs and they had cams and a tune as well.

 

If you assume that the GDI 2.0 and the current 2.0 are simular short blocks. Do you think you could buy and replace the Cylinder head and make the non GDI a GDI???

 

Very biased and inconclusive for the most part on final numbers...and the bold/italic stuff is someone ELSE commenting on another person's review and being a fool saying some stupid s#%t....but anyways...yea...it says in the end starting from next year and within 3 years all the GDI's will be out for Hyundai...this is old news...came out last year

 

yeah i'll post up a dyno sheet, someone on HHOP installed I/H/E and dyno'd at a little under 300, like 298rwhp or something very similar.
Give me a bit to find it.

 

Hate to back up Promo, but here is one that was posted in the Community Dyno thread. He claim's to only have intake/exhaust before the tune.

*edit: sorry my graph has a few confusing parts,

1. All my runs were with the listed mods with 91 octane.
2. Run 13 was after Arvin's tuning on the dyno.

 

Well I stand corrected. Hadn't looked at the V6 dyno's in a while. Bout time the V6's are putting down some good numbers. I'm used to seeing the measley 240-250whp with bolt ons that most V6's post. I'm still baffled by the wide range of dyno numbers the V6's are making.

 

Yea, there a few out there pushing close to the 300WHP figure these days.

 

i think there has been a mention of Hyundai putting in newer updated ECUs in the V6's after a certain build date...this could have been a factor in maybe a newer flash to create more power?

 

Still wanna know if there is a chance of swapping heads to gain GDI later on... Never heard of it being done before so it just curiousity dont flame me...

 

should be possible as long as you swap parts of the fuel system and ECU. would it be worth the power..Probably not..

Edit: I take that back, looking at the piston i'm not too sure it would be possible

 

Why not do some forged pistons while the head is off... Im not so much interested in the proformance gain in this as the efficency gain. I was thinking it be possible swap fuel system and cylinder head and then have it tuned. As long as the short block is the same. If ya have to get new cylinder it isnt all lost. Like my only buyers remorse Im gonna have is when it has DI... Im already planning on buying '11 interior parts and swapping them.

 

We can barely get our cars tuned now, how much easier do you think it will be when you try to swap to DI??

 

A lot easier when we give it time for a genius to figure out the ECU.

 

because we have tons of them floating around here lately..:hsugh:

And imagine this, I wasn't even targeting that comment towards you....go figure.

 

I would hope by then there is more tuners... plus im not far from the guys at SFR...

 

Gen's on it's first few years, give it time.

 

i seriously doubt it for the v6....the Delphi unit iirc is still missing data to allow full tuning

the easy to crack 2.0t data isnt fully completed iirc and we still dont have a way to tune ourselves.

GdI is a pita to tune (most tuners aren't familiar with it), and as a result more expensive for the tunes.

GDI is nice for leaving it stock. Ill take a pass if im making big mods (turbo swapping etc)

Hate to back up Promo, but here is one that was posted in the Community Dyno thread. He claim's to only have intake/exhaust before the tune.

What did he dyno stock? thats very important when it comes to things like this

intake and exhaust putting him at ~294 is bizzare, when other members have intake exhaust and headers and aren't making the same with tunes
