Bk2patt2oh I have a 2013 2.0t rspec
I have driven 3.8 and raced them vs mine the 3.8 will win from a dig all day but from a roll with high Roma the 2.0t can put up a fight in short races but the 3.8 will edge it out by a hair but the 2.0t takes off at 1st now this race was done with a 3.8 straight piped , intake and coils my 2.0t had exact same mods I find the 2.0t to be funer driving it it feels to pull harder and sooner

Bk2 3.8 fully bolted manual w no tune was even, sometimes id win, sometimes not but it was very close every time. Now I have meth and I think I'd take a bk2 3.8 but that hasn't happened yet.
Nice! Thanks for the input.

I still have my factory O2 so I'm not sure if your definition of downpipe includes primary cat delete or not but other than that our mods are comparable. With that said since you asked for 1/4 times I went couple months ago with those mods, factory 19" wheels on Hankook V12's still at 35+ psi:

60' : 2.152
1/4 mile: 13.687
trap MPH: 101.69

Could have cut a better 60' time letting air out of the tires and brake boosting higher which would have drop the 1/4 time a couple tenths I'm guessing. I honestly think you have a better shot from a dig than a roll.
SFR 1.5 lets you brake boost from dig and roll. Brake boost + 8AT allows you to run 4.9-5.1s 0-60mph all night long consistently and faster than any mildly modded BK2 3.8 6MT can (lets be honest, how much *extra* hp does a tune really give a 3.8 to really affect times anyway). Anyone with a tuned BK2 2.0 8AT can chime in and confirm this thing launches decent for an overweight rwd coupe with a 'Hyundai-made' 8AT if brake boosted from a dig. From a roll, like some have said, the aggressive gearing from the 8AT loses the advantage and you get a lot of power sapped through the transmission.

So IMHO, if you want a guaranteed win, run him from a dig. Your 8AT will consistently out-accelerate him. If you run him from a roll, I say with my butt dyno it will be close but you should be able to take him. If you want an advantage from a roll, I suggest you brake boost. Let us know how it turns out!
Ding ding ding! Very interesting perspective...this is what I was kinda looking for.....

Do you say from a dig bc he can't shift through the gears fast enough while we just have to brake boost and mash the gas? - never thought of this.....

Now I need to figure out if I can brake boost + LC with the tune. I was told we had LC with the tune but the one time I tried it, I just spun the rear tires like doing a burn out.

This was the best launch I had that night and I dropped rear tire pressure to 25 pounds. 275 tire

Also let me note that I was BANGING gears as fast as I could. I'm planning to pull the backseat out and the trunk to lose some extra weight and run a 50 shot to see if I can break into the 12's.
Interesting... so that's very close.... BK2 2.0T with a few bolt ons and tune Approx. 1/4 mile: 13.687
trap MPH: 101.69 vs. 3.8 bolt ons and tune 1/4 - 13.2
trap speed - 105mph give or take that looks like a drivers race to me in the 3.8..... one mis shift in the 3.8 M/T and it's a loss lol... hmm.......

shorttrack Ran 11.87 with drag radials finally in the 1/4 at the same mph (117.9).I'm done boys ,time for me to do something else .It has been a lot of gained info on this forum ,if you guys want to go fast against anyone ,NOS is the ticket .Stay in the 75 hp jetting range and work on the suspension .Low 12's and high 11's are doable .Shorttrack.............signing off .
04-16-2016 06:25 PM
shorttrack Gentlemen with BK2 3.8 (torsion rear diff ) install a 75 shot Nitrous system (under $400.00) a 2 dial controller ($250.00) Purge kit ($120.00) MSD shift light with MSD GMR pick up ($150.00 ),under $1,000.00 and be in the 12's with a few more supporting mods .I run 12.07 ET @ 117.7 mph in the 1/4 .(NITTO NT05's are keeping out of 11's .Once my Nitto's wear out ,Drag radials will be my ticket for 11's .Check my post's on GDI nitrous ,If you want to run FAST without going broke and breaking down then Nitrous is the key .

I was told by Hyundai the 2013+ 8AT is Hyundai's. now the BK1's were ZF but the BK2s are Hyundai's transmission. Was told by an engineer they got away from ZF due to too many issues. IICRC ...when I asked the tech at the dlr how the tranny's are he said they haven't really had any problems just the previous ZF's in the BK1's. the BK2's so far they're holding up and I think he mentioned something about MOBIS.

Hyundais 8AT isnt anywhere close to a true ZF and like I said, is in all likelyhood a very cheaply made version.

If it was a true ZF thats used in the likes of Hellcats, I wouldnt have argued with you.

Gencpe Thanks for everyone's input....i'm sure we'll be racing soon....but when we do it'll probably be on film so i'll post up if that happens. If anyone else has anything to chime in about pertaining to the OP please post

Only issues I recall with the ZF 6 speed was with the shifting cable.

On a side note. apparently hyundai now has carbon syncros in the 6 speed
Yes, that's what the engineer told me IICRC the latest trans. are ZF copies made by Hyundai and branded as such instead of using a straight German made ZF.

The thing is even the 2013 Manual's seem to be having some problems when put in gear...something about grinding not sure but I already know two people who have complained about it and one that has replaced their transmission twice now. but then again idk too much about the M/T's in the gen coupe as I have the A/T.

This is correct sir. the 3.8 is a 6 speed M/T and just a canned tune not sure if it's stage 1 or 1.5 SFR. He has an injen intake and magnaflow CBE if that matters.

My mods are listed on the first page.

From a roll stock, he would beat me. Very even on the low end, but he would pull me on the top.

After I began modding my car, most of the races were nearly dead even. I did some more modding, so has he.

He decided to go 6266 turbo and from a 20, and a 40 I would pull him about 1-2 cars in the beginning and he would eventually catch up and make it even towards the end.

Before he went big turbo he had the stock turbo and I had all my mods done. Tune, full exhaust (header, mp, cbe) Races were nearly the same, maybe me winning by a fender or half a car.

Both cars are 2015's In Ibiza Blue Track Models. 6MT.

tl:dr - The 3.8 has instant torque so it will jump on the 2.0 from the beginning. If you brake boost the 2.0 from a roll they're dead even cars. In your case, the A/T car might fall behind due to the fact of the gearing, etc.

I'm basing all this evidence above from **** that has happened with me.
Thanks for your real world input. this is what i'm looking for is either dyno #'s vs. Dyno #'s but preferably 1/4 mile times.

Interesting....the only thing is that I have an A/T...I know from a dig the 3.8 has more torque most likely.....but from a roll.....all the way up to 130+ who knows right?

this scenario is a bit unusual since we're talking both BK2 in 2.0T 8-speed A/T vs. 3.8 M/T 6-speed. both with a tune.

I was told the opposite due to the 8 speed vs. 6 speed gearing once you hit high triple digit speeds the 8 speed walks the 6 speed....and the guy's testimonial who claimed this apparently has seen this IRL. but the only issue was the 2.0T was tuned and the 3.8 was stock so not much of an apples to apples race there.
