Stage 3 TTE810 daily driver realities....

[EVONILS]

so tempting to go stg3 with TTE810 on the daily with 91oct.

Guys that daily with this set up, what are the realities of it? any weird quirks or set backs? how's the spool compared to OEM peashooter? any unexpected issues?

Any owners that daily at these power levels that have real world insight pls do share.

tia.

The realities likely go from blown engin to no issues.

I'm running the TTE810 for the last 18 months on 93 pump. So far no issues and no surprises (relative to what you might encounter being tuned in general). If at all, surprised how daily isn't impacted by being stage 3. But I do follow with shorter maintenance intervals (sparkplugs etc.).

Turbo spools frailty quickly, based on logging I did, it's fully spooled at around 3100 rpm. Sure, not like OEM, but, that surge for power lasts all the way till 7k rpm and it feels amazing.

[EVONILS]

good to hear that the daily aspect hasn't been affected too much.. 18 months and going strong (fingers crossed), love it

^ Yea, I think when you play with E85 it can become a real issue quickly. I am hoping to go to a TTE 810 in the coming year and I am just gonna play with the 91 octane file.

Though I did see something yesterday about the CTS Boss800? But people quickly chimed in about the source of their turbos? Anyway, good to hear the 810 is treating you and your wallet well!

Why is the APR DTR8868 not getting as much attention?
Is is from a lack of tuner support? Or Something else I am not seeing.

Not to say the TTE products are not worthy of their popularity. It just seems the APR offering also looks very good but just isn't on as many peoples list.

i find this talk of "fully spooled by 3000rpm" pretty funny... I dont see max boost until after 4k I cant imagine the 810 spools a lot faster on pump gas.

[ontunerow]

Well, take it or leave it, not in the business convincing anyone. I'm just sharing from what I saw when logging few pulls. And I saw peak boost reached at ~3100.

[ontunerow]

Btw. Looking at 034 dyno charts, on 93 it shows peak boost before 3k, whereas on E60 quite a bit later, around 3.5k.

[S4James]

fair enough, i think i remember the 710 profile as the 810

[A4 Centaur]

I have been closely watching the APR DTR8868 and for peoples reviews of the turbo. Haven't seen a post yet about a blown engine with this setup. And I hope we don't.

That Christmas sale was really tough not to buy one! $2700 would have been a great deal. I'm probably going to just do the TTE 810 in a few months. But that APR kit is tough to beat cost wise.

As I mentioned previously it would seem that CTS Turbo is going to have a B9 Boss kit released shortly as well.

[S4James]

I can tell you things dont start happening for my APR turbo until around 4k.

The big two tuners don't support it, and the big two tuners are the ones with big marketing reach.

Otherwise, the APR turbo performs extremely well - and without some of the constraints the 750 and TTE810 have.

[Jetta03]

What constraints?

I hear ya but this thread wasn't really meant to discuss different set ups, one turbo vs the other, etc... just more about the car itself and how it handles & acts with the extra load. But since you asked, the post below is fairly correct I think, im sticking with 034 for the build simply cause I used to see them at the track testing all the time back in the day when I use to compete in time attack, I like tested, proven and simple...

makes sense.

where is the [CHEERS BEER] icon in this place??

As to APR stage 3 spool, here's my experience.

I tested from ~1,500 rpm till ~6,000 rpm at WOT except for "standstill" (= red line of 7,200 RPM). I charted RPM, specified pressure and actual pressure. When the latter two are equal, I presume the turbo has spooled and noted the RPM. Here were my results:

Standstill: never (actual pressure only reaches ~70% specified pressure )
1st gear: 6,000 RPM
2nd gear: 4,600 RPM
3rd gear: 3,400 RPM
4th gear: 3,000 RPM

Not sure how tuners are testing for it.

As to the original (original) question, a larger turbo will take longer to spool, push the powerband up the RPM range and in this case, have a higher red line. Without lower/different gear ratios, the vehicle will be less responsive and spend more time in each gear. It's still completely daily drivable for sure but feels like a different vehicle when it comes time to hit the go pedal - much longer 'legged" if you will. When fully on the go pedal for an extended period (such as a 1/4 mile or 60-130 mph run, there is no discernable decrease in responsiveness - she goes like hell!).

[S4James]

I guess we are assuming that APR is not tuning these things for "MAX" boost pressure (the boost guage on the dash) right out of the gate correct? The torque seems to be limited in such a way for safety.

I'd say they are tuning for max boost. Here's 3rd gear. As soon as I WOT (Time = 1000 ms), specified pressure quickly goes to maximum but actual pressure takes 4400 msec to catch up (Time = 5400 ms). Maximum specified pressure is the same for all the pulls I did (3000 HPa = 42 psi). Actual lag time increases for each gear since the car (and engine) will accelerate slower, but the max boost RPM decreases as there is more time for the turbo to catch up. For example, the 2nd gear pull chart looks identical save that instead of 4400 msec to reach max boost it takes only 3000 msec and max boost RPM is 4,600.

FWIW, APR says they did a lot of torque limiting when it comes to launch control and shifting (which isn't reflected in this chart) to protect the drivetrain.

[S4James]

ok.. looks like im a touch laggier from my experience.. but i also start my runs at MUCH higher RPM so thats probably all it is.. ill make a note to try a pass from 1500 and see if i get similar results.. Basically I feel the car start to really move after 4K

[S4James]

Bump, did some testing, my max boost is shifted 500rpm to the right. Its definitely not spooling as fast as you. Mind you i have stock downpipe/exhaust. Dunno what the previous poster has done.

[GoCougs1234]

I also have the stock down pipe and exhaust plus I only ever run 92 octane on the 91 octane tune. I do have an aftermarket intake (IE), which will let the turbo spool faster than the stock intake.

[S4James]

yeah, i guess mine is just a touch slower then.. Might be some differences due to the fact you are in a completely different car too though.. :P

[Gsdg005]

Have either of you gone up against any m3’s or m4’s?? Curious as to how you fared??. I’m currently running the E 85 tune with an intake And I could definitely hang with a x3m and mustang gt and will pull on mustang after 100 or so. I’m very interested in the turbo upgrade.
