Is the TD05/06 a direct bolt on a my99,or is the plates to lift the inlet nessesery???

John are you saying that it´s not possible to get more 350hp on the flywheel even if You raise the boost more than the 1,25bar??


Skassa

Mr J

Skassa you can bolt it on the MY99 right away
Just adjust/mapp the link

John ~how much timing can you get away with before it's start to be noisy @ 1.3Bar ...just for a referanse sice I run a link and you EcuTek.

Would be nice to know/ compare it in ex 3000rpm >redline

I did notice that running ~1.5Bar It did retard on track

Whether it is 350 or a little bit more depends on rollers etc, however, raising the boost LOSES you power on T-uk's setup on pump fuel, have seen similar on most other cars. To get a TD05 with headers to run big top end boost with a 3 port you end up cranking up the wastegate duty, this has to be a bad thing even with a weak actuator IMHO, as exhaust manifold pressure is trying to blow it open. So you gain pressure but lose flow, you retard the ignition and add fuel to control the det, and end up with a less safe, slower car. With octane booster you can run a little more boost to hit the sweet spot, but the main gains seem to come from more ignition advance. It is very easy to run too much boost and not enough timing and kill it flat on its face.

Think it was about 16 to 27 degrees from 4000 to 7000 RPM. This was logged off Delta Dash. Would need to check the laptop as this is from memory, but ballpark, take about 3 degrees off without booster.

Thanks John

loocks pretty close to the timing I run with the link(but link starts @10deg..i think..) I I do run more timing down low..
ButI run 14(24) with out any x-tra in the tank, so that's the same.


Hmm I geuss the retard is because I run ~13-14(23-24)@the spool up... theres were I have had problem @ the track.

And I do use the Dawes for boost control peak ~1.55Bar and falls down 1.25-1.45Bar depending on gear @+6000rpm.

On my TD05,with manifold,MRTinlet,I have run 1,45bar tappering to 1,3bar/7000rpm,
And my link log is showing 13/14 degrees between 4200/5500 and then up to 16/17degrees at/7000rpm,
But i also destroyed a piston with knock at around 4800rpm....

Mr J

Looks like it's best to take some timing of @ the lower rpm's then....if not having some thing x-tra in the tanks that is

Would be interesting to hear your experience John or any body else that have tuned a lot of high powered Imprezas

Most UK/Euro maps need a timing retard at 4400-4800 RPM and more fuel to get rid a lean spot there. You can advance the timing quite aggressively at 5200 RPM usually. Dependson the engine.
6000-6400 is another plateau on several cars, especially if you are too heavy on the boost, this affects the peak power a lot, hence you can often gain here with a little timing in exchange for boost.

Except my car which has 'sparkley' moment at 5600RPM, knock count in the Link can jump 10 points and the first amber light on the knocklink, have to pull about 3 degrees to make it go away.

Otherwise I can run from 13 upto 16 degrees with very little noise.

Just for info - TD06 vs TD05 both running so much octane booster I may as well have just pi***d in the tank But at least you can compare. Both standard headers, same car, similar boost etc.

Thanks for the website link to the Aquamist water injection system...I seem to recall the World War II Republic Thunderbolt fighter had a water injection system to supplant the Turbo buried in the rear fuselage (about the size of a dustbin). Added about 400BHP to around 2,800 BHP in all

Seems like a black art to me.....I think I'll stick to things I can just about understand.

Thanks again
