TD05 on Ebay

Actually Matt I just did it in my head, estimating most of it. If you could get a more concrete number Id be very grateful.

edit: Darnit. I didnt win

Guy comes in with a bidding frenzy right at the end and kills me.

Ok,
I did the math and 16.5 is really pushing the limits of efficiency for the TD05 (small 16g). 16psi is still on the map, but at 7000 rpm you are out at around 60% efficiency. Even if you run your redline at 6500rpm, you are between 65 and 68% efficiency. Personally, I wouldn't run this turbo on a 2.2l past 15.5 psi with my desired redline on a built motor of 7000 rpm...

Something else to remember, this turbo is bigger than our stock turbo and will push much more air at 15.5psi than a VF-11 will push at 15.5psi. Many times I see discussions about upgraded turbos and a huge emphasis on how many psi of pressure, but so often how many lbs/min of air flow are going through the thing is totally ignored. PSI is not the end all measurement of how well a turbo will function in your desired build...

What type of Volumetric efficency should we use when calulcating?

I guessed 80%
How do these 18 psi calcs look?
rpm cfm
3000 190
4000 250
5000 315
6000 380
7000 440
2.22 pressure ratio

I know I've seen somewhere a compressor map that shows the max CFM of a small 16G to be greater than 500. Also, on the same map, 20psi was still on the map, just a little out of the efficiency range.

520cfm according to my comp map. PR of 2.0

Ciper,
You pressure ratio fails to take into account loss of pressure across your intercooler. I generally use 1.5 psi loss and for 18psi would get pr 2.24. Also, I have read that anything above 70% efficiency is acceptable.

Furthermore, I probably should have run more numbers. Specifically, if you run 20psi at 4000rpm it is still well within the efficiency range of the TD05, you just need to be sure to have good enough engine management and tune that you taper it off to less than 16 psi by redline...

I won a TD05 for 150 usd shipped 2 weeks ago

Can't wait to get it in the car.

Mark,

Off Ebay? Do you have it yet? You're sure it's not a TD05 off an Eclipse? Just wondering, if it is one off a Subaru then you got the deal off the century Mark.

Hmm, how much do you guys normally pay for TD05's?

FrmRgz2Rchz · Post by **FrmRgz2Rchz** » Sun Feb 15, 2004 11:21 pm

I talked with a guy from the UK for over a year trying to get him to sell me my TD05. He said he wanted to sell it, but he still had to pull it off the engine. Then he'd forget about me for a couple months and I'd e-mail him back and tell him I still wanted it. This happened several times. The price started out at $150, but then he said some bull about selling it for a friend or something and they wanted more, but I ended up getting it for $300 shipped.

Yup off ebay, its a TD05H 16G off a UK spec 1994 wrx. 50 000 miles on it.

Cool, you're super stoked! I wish I could find a deal like that.

i got mine for 300$ USD too. 10 000km on it (but.. looks brand new).

i dont get u guys. u dont have to change the turbo. its all in the down pipe and intake of the turbo, free it up and the power will come. but make sure u have a intercooler.

No offense, but your car probably tops out at 260hp or less. Some of us want more than that. That is why I picked up a VF-28 in my quest to break 300chp...

morgie · Post by **morgie** » Mon Feb 16, 2004 5:54 pm

yup, the 340-like Cfm of the Vf11 is just not enought

I want 18psi to the redline a 7500rpm

The VF28 will give you really good mid range, but drops off a bit at the top end, around 6000rpm from memory?

It will make 17 psi at 7000rpm on the EJ20. I haven't looked at the numbers for a while, but obviously is would be little less on the bigger engine. The beauty is you've got full boost by 2900 rpms and will hold that all the way to redline. How sweet is a 4000rpm powerband!!!
I have this feeling that it won't be enough once I have an engine built that can handle 400+ hp, but it is a good starting point...

MY92 · Post by **MY92** » Mon Feb 16, 2004 8:37 pm

Most definately.

I had a VF24 until the exh wheel decided to let go and ended up in my resonator.

I got a TD05 cheap to replace it and the TD05 is definately much nicer up top, but mid range sux compared to the VF24.

I'm seriously considering getting a VF34 but for that money, I can probably get something like APS SR40 for a bit more.

Matt Monson i can get 21 psi at red line, if i set it to 21 psi and thats the factory turbo. the factory turbo spools up at 2000rpm and it gives me 18psi right to red line in all gears. i have never dyno my car but i have raced sti,911turbo,zo5,m5,and 12sec civics with juice and a hand full of street bikes, they cant keep up 0 to 5th gear red line i beat them all. i am going to say i have 350hp to 380hp

LegacyT · Post by **LegacyT** » Tue Feb 17, 2004 12:05 pm

21 psi on the stock turbo??? Maybe thats why you keep blowing your motor? You can make that king of power much more reliably with a bigger turbo. I don't even want to think how hot the intake temps are at that kind of boost with a stock turbo

What fuel pump and injectors are you running? Aside from that it is ludicrous to run 18-21 psi on the stock turbo because that is so far outside the efficiency range of that turbo. As mentioned get a bigger turbo. As for your kills, sounds like a bunch of juvenile spray to me. Noone meant to insult your manhood, but your kill list prooves that you really are a man!

the fule system is all stock i did nothing to it only a valve on the reuturn line thats it.
everyone on this bord has told me my turbo is out of its range but u no what, the turbo does not even break a sweet. i can race my car all day long and the turbo will never get red hot. mitsu mazda all the turbo cars out there get there turbos red hot, not my subaru.

legacyT my motor was rebuilt at 170thousand ks now i got 553thousand Ks on it and it only needs piston rings everthing in the motor is perfect, new gaskets and away i go agian. 2 more weeks and its back on the road.
