Just want to let you know what the TD05/06-20G,will do in Denmark on straight 98 octan, at 1,4bar to redline.

372,3hp/6239rpm - 452,6nm/4264rpm,

This is 40hp and 40nm better then the TD05FE on the same boost

there is 425nm from 3500rpm all the way to 6300rpm,so the curve is pretty flat.

I was hoping it had made a bit more hp,but itīs okay.

This was with a AFR of 11,0 from 4500rpm and up and the link advance from 12degrees/4500rpm to 16degrees/7000.

I wonder how i can make 30-50hp more as most of the TD05/06-20G has made in GB???.

I thought that Andy was the only one up at this sort of level

30-50bhp is a number of factors

1. Use of NF and/or Meths/ and/or some other mix type
2. Running more Boost
3. Loose rolling road numbers!!!

I am expecting over 400bhp on this Turbo next weekend at the G Force RR Day... but then I run more than 1.4bar boost and use NF

Plus depends how its mapped.........e.g. more advance

Denmark

iTrader: (2)

I canīt run more advance with out booster,but it is also a good result..

iīm really happy with the way that it drives with this turbo,but i saw that there was another that made over 400hp on plain 98octan.

Maybe that supersprint manifold is a bottleneck in making more power?.

Thanks,
Skassa

Skassa,

I've pretty much the same results in a customer car also equiped with Supersprint manifold! (measured with Delta Dash and using 1.26 correction between wheels and flywheel power)

I had about the same results at 1.35 midrange and 1.25 @ 7000 RPM, more boost only gave me more midrange power but not top-end. (I had to retard the ignition to keep it knock free) I think the 98 RON fuel is holding me (us) back!

I also mapped it to 11.0 AFR (about) and came about the same advance......

P.S. We will try a different uppipe later, as the Supersprint uppipe has a minimum diameter of 41 mm. This seems quite restrictive to me! I will have the Supersprint uppipe modified to 45 mm diameter.

Mark.

I will be doing similar exercises on the 2.5 starting from low boost and working up. I will reconnect the 3 port and try some different top end boost profiles. I suspect also that a big midrange boost hit with less at the top but lots of advance will be the way to go for me.

I havend tried to run it at a lower boostpressure ,as it just fells right,as it is,but maybe i will try to lower the boost and then see if i can up the advance,and then see if it gets better.

But overall iīm happy with the way it delivers the power right now ,so i will see if i change it.


maybe itīs like in Denmark with the hp rating(in GB),when you go to the east of Denmark ,you can add VAT on top of your HP rating
So maybe i could go east a get a good hp measurement

Thanks for the inputs

I got the dyno sheed if someone can upload it ,for all to see ,then i can mail it as a jpg.

well Done Skassa, glad you got the results you were looking for

AlanG

To get more power like some in the UK have got depends on what components are used and how the car is set up. Same rolling road on the same day will probably get rid of any discrepancies.

Mine for example has a different intake and exhaust manifold and system to yours. My peak power is also made higher up, so i wouldn't look too deep into the actual figures.

You will probably find our cars are very similar out in the real world, on the road.

Nice and flat

Alan,

From the text,is your engine gone???

Maybe 372hp is okay,and then it will hold


I have mailed it to you.

Hi Skassa

Got your mail and have replied.
Can someone post Skassa's graph? Very very nice torque curve!

Comments ?

Indeed, very early torque for this turbo in my experience

What sort of acceleration rate was this run at ? ie how long was it at WOT from 2000-7000 rpm ? What make was the rolling road ?

This was actully a roaddyno called Dynomat,

There is a plate put on the wheel,and the car weight is put in a cumputer,you can see that it weight is 1470kg with full gas tank and to people in the car.

Between 6-7k rpm there is a drivetrain loss at 102hp,but this include windresistence
This is the actuel hp that the car got on the road,
It is measeured in 5th gear of the 6speed,so this the time is what is take to go throug the gear on the road..

Skassa

Andy.F

I would have thought the total drag and drivetrain losses at 6-7k in 5th would exceed 102 bhp on a Subaru ? What speed are you doing at that rpm ?

Andy

Pavlo

Hang on a second?

From what Skassa just said "This is the actuel hp that the car got on the road" are we to assume this is wheel hp?

Paul

Jolly Green Monster

iTrader: (4)

wheel hp?!?!?! **** me!!

LOL

Simon

Andy.F

Can't be PAW otherwise it would be 474 at flywheel and the tdo5 made only 40 less

6-7k in 5th must be around 120mph and the aero drag alone must be around 100bhp, then add the trans losses of say 22% of total ?

Denmark

iTrader: (2)

Itīs flywheel HP ,and it run on the road.

The guys who measured it said it was 102hp loss to the wheels,between 6-7k rpm.

I have tried this dynomat before, against another real 4wheel Dyno"Optima 2000" and there was only 2hp difference!.

Sorry, i will get it on the same Optinma 2000 ,as i have run on before

Skassa

Andy.F

No problem Skassa, I have also found the AP22 matches well with our local rolling road, I can usually estimate to within +or-5 bhp what my result will be on the rollers.

What your graph does show is how early the turbo starts to pull on the road, this is not always captured by a rolling road print out.

Andy

Denmark

iTrader: (2)

Yes,but this is a bit more advanced then the AP22

This is indeed the best turbo match for the car and i really love it.
I donīt think it can be matched any better

Maybe i will sell the car now and then get myself a newer Scooby,and then start over,but aleast now i know what parts to buy

Thanks,
Skassa

td05/06 - Cant wait to see what the power of this gives at G Force this Saturday

Must say since my latest mapping session with Bob we added water injection and the power kick is now stunning

Whilst there are other Turbos out there that give a realistic 500bhp (or a little more with a little help from High Octane sources!)on the road I think I'd rather have this Turbo for sheer driveability. What I guess I need to do is drive someones car that has the large turbo on and see what I think - I dont think I could now go back to a laggy car!!

If I can get 430-440bhp on a really responsive car what more do I want!!!

Andy - have you sorted out the shroud thing yet - so I can have the boost in quicker? - that would make things very nice.......

Andy.F

Still dabbling with that Steve, not much more to come to be honest.

Andy

Skassa - a bug-eye? For track work? Are you nuts? While the handling can be made very, very good they just don't change direction quick enough in comparison....IMHO

Skassa,

How much work was the installation of the TD05/06-20G ?

I own a STi My03 and I am a bit interested how much work it would be to replace my stock turbo and I still have a ECUTEK-custom tuning with my tuner...
