Who here is running a T04E/K26 #8 Stage 3?
interested in seeing what some basic setups are.
I am thinking this turbo is to big for what I want.
yes I said to big. I am only looking for 333rwhp.
I looked at the map and it seems to fit nicely unless I did my numbers wrong.
attached is the compressor map.

ps. I DEFINITELY do not plan on running a MAF kit.

But I have a AFM, Throttle and intake that allows me to flow about 28% air more than stock. I also have a sealed set of #55 injectors, 3 Bar FPR and Tail 38 WG.

what boost do you want to make the 333 hp at?
do you have a stock exhaust?

I had a t04e/6 and it can get you to the hp you want,

but then again I also had a 27/6 that made that amount of power (with an MAF and exhaust, but stock: intake, intertcooler, hardpipes, head, headers etc) and it spooled 300-500 rpms earlier
the 27/6 made it at 20 psi

the more info the better...

I dont want to run more than 16 or 17psi.
stock pipes but high flow cat and ansza muffler.
Chips wise, I have about 5 sets from g** only knows who.
One or 2 from known vendors, I will get a A/F meter to make sure all is dandy.
Boost will be set manually with a custom unit. I converted the cluster to recalculate down to turbo bar.

I dont mind doing a custom chip setup and paying for it.

emwporsche

well I had an anza muffler too, and the rest of the stock exhaust got replaced with a ss 3" exhaust (no cat and I still passed emissions)),
it made more peak power, sounded superb, but best of all gave it way better throttle responce, faster spool-up and a better powerband (more power down low)

get a vitesse chip, I've had many but this thing instantly made my idle better, and will give you more/smoother power.

oh and don't bother with an a/f gauge unless your going wideband.
I believe there is a groupbuy here on the list

Please do tell. How did you make that kind of HP with a k27/6? That seems 30-40hp higher than typical. I am not bashing you, I just want to duplicate 333rwhp with a my K27/6.

My turbo has lots of lag and I doubt it makes anywhere near that power. I am running 19psi on mine without a full 2.5 inch exhaust (no cat) and MAF. That just seems like a whole lotta power out of a k27/6.

I have thought of changing to a #8 hot side, but the lag would be horrible methinks. I can't even get full boost in 1st gear as it is.

Now I must add a little to the story. I am at 6000ft so off-boost performance REALLY sucks and spool-up is much slower than when I drove the car at sea level. Also, 19psi here is about like 16psi at sea level (we have about 3psi less atmospheric pressure here (around 800mbar is a typical day here vs 1mbar).

Well 4psi plus a maf kit should be close to the 30-40hp range.
I believe that most of the internal parts of the stock setup can handle 340whp, but i dont think it's a good idea to run them at 100% duty cycle. that said it's possible "on paper" at least to get those numbers.

emwporsche

maybe a 27/6 can't get you there.

I don't have experience from any other 27/6's other than my own
(I sure would like to see what the average person is making with these)
(what's the max boost you guys are getting? spool-up time?)

I wish I knew the specs of mine because aparently it was far superior to what other people are getting.
I don't know if or how it was modded- I bought it used from a racer.

Spend an afternoon in the archives, a 27/8 is waaaay to big for a 2.5l....

hally

hmmm most of the garrett hybrids guys seem to be runing with a #8 hotside & a stage 3 wheel, and if a K27 cold side is considered eqivilant to about a 48 compressor wheel if what i read on the lindsey site is accurate... so how come a 27/8 is considered big relatively speaking?
thks

I have a T04E/50 trim with #8 hotside and you can see the numbers in my sig. Mine are a bit low due to an exhaust leak.

Most of the K27/6 guys seem to have made around 315RWHP, where the T04E seems to be around 335RWHP.

snappy

So Mike, if you ran a 50 trim that gives you about 47lbs/min Flow right?
On my 57 trim it would be up to 49lbs/min, right?

I wonder what that will do to spool-up times.
It looks like I might hit the 333whp @ 16 - 17psi with this turbo if I can dial it in correctly.
I was worried that it was to big.

Mike Murcia

emw, Is the k27 you speak of the one I got from you?

GaryK

I replaced the K27/6 that was on my car when I bought it with a TEC T04E, which has a custom hotside. As you can see from the pics, the hotside housing on the T04E is no larger than the one on the K27/6, but the turbine wheel definitely is. With the T04E, stock (but freshly serviced) injectors, 3 bar fpr, Authority MAF and chips, a 2.5 cat bypass pipe and Borla exhaust, and a simple manual boost controller set for 17psi, the car made 308whp.

The Authority MAF and chips were purchased by the previous owner as a kit with the K27/6 and 3 bar fpr, but work fine with the T04E, other than the A/F mixture is a bit rich up top. Maybe at lower altitude it would be correct.

I never dyno'd the car with the K27/6, but it had more lag than the T04E, and less top end power as well.

And Hi Dana....haven't see you in a long time, nor have I ever had the pleasure of driving your car. Wouldn't it be nice to drive down to sea level sometime and see how these turbos can really spool up?

GaryK

Oh yeah, I forgot... my T04E is a 46 trim.

"emw, Is the k27 you speak of the one I got from you?"

if you bought a 27/6 off me, then yes.
I have lost track of who has bought what!

did you just rebuild it or change it up at all?
what were your results with it?
that turbo was a powerhouse
if the rebuilder provided any specs I would love to hear them
