What turbo's you guys running with Stage 2

Post by RJ93SS »

What turbo's you guys running with Stage 2. I know the td04 is what is meant for stage and that's what im running right now.
However, i have a TD05 staring at me in my garage and it's flipping the bird at me as it sees me leave the driveway without it.

so, what turbos are some of you running and what results are you seeing. Obviously 17psi out of a td04 is alot different than 17 out of the 16g.

My main concern is knock. Hopefully someone is running one with a wideband or is datalogging to let me know what they think.

Thanks in advance for your input. :lol:

TD05 will push 440cc injectors too close to ~80% IDC during peak boost. If the ECU detects too much knocking, it'll enrich the fuel too much and the injectors then get maxed out (90-100% IDC) -- even only at wastegate / 9 PSI. Better go with the 480 or 550cc ones instead.

If I ever get this car functional, I'll surely be doing more data logging of things.

I got 550's, im good there. Im wondering about maf voltage on 17psi. i must be close to maxing out the maf. If i put the td05 on maybe i should stay out of power mode and just run 13psi.

since Ill be getting your turbo :D, how would you compare it to the VF-11 without changing anything else, or is that something you have experienced? I currently have my TMIC on, and my vf-11 is set at ~13 psi. do you think I will notice any changed just from switching to the TD04? I plan on doing 550's JECs, revtronix stage 2 chip, but not till I have enough money for all 3 since they can't be added 1 by 1.

wow man, gl with your car. Your link led to other links which led to my wife getting mad at me for being on the cpu so long. But i learnt a few things.

Cheers.

When my car was running properly the car hauled ass stock with just a td04, intercooled stock injectors.

Sounds good haha. My car is pretty quick right now, so stoked to get the RT stg 2 set up for sure. I'll let u know when my check is here

With stage 2 when running properly it is like a wrx, if anything faster IMO. Considering I was running automatic the car really hauled ass, I think the 0-60 was timed at 6 sec (NO auto launching) with my friends phone. If it was 5spd would be much faster. I was very satisfied, I was dissatisfied with my self control of 17psi .....

my bad, my response was for BSOD. I had not refreshed that page since i started reading his link so your post was never there.

As far as vf11 over td04, i would say the car felt smoother through boost, i seen better gas mileage and less hesitations. Power wise it felt pretty good maybe 10-20 horse at 8.7 psi. The downpipe really opened it up a few weeks later too.

The chip is where youll really see the car wake up.

Will it run with your STI?

its ok, I was just slightly confused haha. Well that all sounds pretty good to me, Im stoked. Im pushing about 13psi so I should see pretty damn noticable gains. I am soo excited to get the whole stage 2 set-up. All I need is the 550's, the adapter kit, the N/A rails, and the chip itself. Money, money, money, MONEY!!!

Bare with me as I have alot of info and it may scattered around as I'm writing this.

I've been running the 90* Subaru TD-05 on the stage 2 TD-04 chip and has been running awesome, the BCS works but it fluctuates between 13-15psi on Normal mode and 16-18psi on Power mode, I don't like this and it never stabilized so I just use my MBC set anywhere between 12-16psi. AFRs seem fine and I had ZERO knock w/TMIC(all I run is 93 octane) , but with the revscan cable you can manipulate WOT fuel trims if you feel like it needs a lil more fuel. Acoording to Mike at Revtronix the JECS MAF maxes around 16.5 psi on the TD-05, I feel this will vary depending on how free flowing your intake design is, IDK. Mike also told me 90% IDC is fine but no more, I was always under the impression 85% IDC was the highest you should run them for prolonged life.

I took my car to the track 3 times with 3 different setups but can only find 2 of the setups time slips.

First setup: Stock EM, stock injectors, 04 TMIC, intake, exhaust, FCD, TD-04 @16psi(yes i'm sure the MAF was maxed).
Best 1/4 mile time was 15.296sec @ 86.81mph with a 2.088sec 60', best trap speed was 88.33mph with a 1/4 time of 15.382sec and 2.299sec 60', IDK how this happened.

Second setup: Same as above but with a VF-8 @16psi, again I'm sure the MAF was maxed out. This is the slips I can't find but I remembered the times were almost the same but i gained about 1mph in the trap, I think it was 15.2sec@89.-mph. I attributed the times being so close because the injectors were maxed each time and I needed more fuel to make any difference.

I ran the VF-8 setup for awhile untill the Revtronix stage 2 VF-11 chip came out. Like a dumbass I bought a VF-11 because I thought you had to run it with the chip, so i took off the VF-8 and set it on the shelf. This setup was still the same as above but with the stage 2 VF-11 chip and 480cc injectors. On power mode with the BCS hooked up this felt faster than the two previous setups, I'll guess a 15.1sec @ 88mph.

I ran this setup for awhile untill I stumbled upon my TD-05 which brings me to my third setup I have a time slip for.

Third setup: Revtronix Stage 2 VF-11 chip set on Normal mode, TMIC, 480cc injectors, TD-05 @16psi.
Best 1/4 mile time was 14.725sec @ 92.42mph with a 2.175 60', when i launched my boost/vac gauge was at 0psi. To defend my self this was in the middle of August with outside air in the mid 90's, I could barely keep my hand on the TMIC due to heat soak. Weight of vehicle with me is 3480lbs and I weigh 330lbs of that, From my understanding 100lbs is about .10 sec, so someone that weighs 200lbs less than me should have run closer to a 14.5. Also from what i understand every -10*F equals 1% increase in total power, so if I had 200-220hp and the temp dropped 50-60*F, there would be a 10-12hp increase. From what i understand 5-6hp is about .10 sec, so with the right temperature and the right driver this run could have been a 14.3 or faster, maybe someone might have some beter info on this. I ran this setup for quite awhile and it ran awesome, enrichment comes in sooner on the VF-11 chip between 3-5psi unlike the 6-8psi on the TD-04. I do like the earlier enrichment of the VF-11 chip when running the TD-05 it just feels more powerful at part throttle, but I'm not having any knock or problems with the TD-04 chip.

I got a chance to get an update on my chip and just upgraded to the Stage 2 TD-04 and also upgraded the injectors to the STI 550cc(mine are really 530cc). Never got a chance to get back to the track before it closed for winter. I've since upgraded to a FMIC, MSD DIS2/MSD Coil, and much better intake design. Now that I have the FMIC I run the chip in power mode all the time but use a MBC to control boost, ZERO knock and 95-100% Octane factor all the time. I have run 20 psi for short bursts until fuel cut kicks in, but still no knock, I know this maxes out the MAF but it just runs very rich, I don't do this very often at all. I have a feeling my current setup on a cold day with someone that weighed 200lbs less than me would run a 14.00 or faster. The track opens back up at the end of march so I'll let you guys know.

So to sum it up, if you've been running the Stage 2 TD-04 chip w/ 550cc injectors for a awhile without any problems you should be fine slapping that TD-05 on there. If your just swapping turbos and not chips or upgrading injectors, I would not reset the ECU. I would however just run 10-12psi at first and keep an eye on your AFRs to see what's going on, then slowly turn it up to about 16psi or right before the MAF maxes. If you can get the stock BCS to work I would recommend that to avoid the PTFB issue, in normal mode it will probably be a couple more psi than 13psi, but still not max out the MAF. If all your sensors are in good working condition then the AFRs should be fine, not optimal, but definately shouldn't cause knock, your biggest problem will probably be boost control. I remember Mike saying something about if your running Normal mode with the reduced ignition timing the EGTs will be slightly higher than Power mode, so if your using a MBC in normal mode keep boost down.

Brian
P.S. When you look at these times remember this is a AUTO WAGON and it bounces off the rev limiter on the 1-2 shift, but feel free to poke at my times.

Love the detailed response, it is much appreciated and i really could not have asked for more.

I weigh 310 so no weight savings here, and power heated leather seats dont help either.

I got the td05 on, but im keeping it on normal mode and keeping the boost around 12, im kinda afraid to open it up until it learns a little better. i reset the ecu. When i go to the track in april we will see how things go. im going to take out the stereo and have only the stock drivers seat in. Maybe i should go on a diet too. :roll:

Thanks everyone for the responses.

Cheers
