IT'S ALIVE!! biggrin.gif

Today we finaly got everything done what's needed to let the engine run. After 10 minutes wondering why my E-manage and the starter don't work, my friend simply asked me "immobilizer??"... unbelievable how fast you can forget something like that laugh.gif
The engine runs a bit rich at idle and closed loop didn't worked, maybe a problem with the stock lambda probe. Tomorrow we put the car on the dyno and i try to set up the E-manage so that the car will run not too bad with boost, fine tuning will follow the next weeks.

Short video

and some pics

Dyno video smile.gif
First run with some engine knock because of too advanced ignition timing making the engine stutter above 5000rpm, i retarded the timing about 2-3 in the next runs.

im watching the video but i also notice some knocking sound behind. Is that the engine knock sound you're refering to? Coz i can hear it even on low rpm and gradually increasing as ur rev up

The loud knocking sounds are from the dyno. The actual engine knocking isn't audible but you can hear that the engine doesn't rev freely in high rpm. Too bad i don't have a video from the other runs.

I finally got the car back and it runs great, the exhaust is relatively quiet but sounds wonderful. The E-manage works great but i have to do some settings till ignition and injection are perfect.. still get some engine knock but not as bad as with the old spark plugs. I just did a short test drive on the Autobahn smile.gif i never was that fast on >110mph and the car still pulls very hard, but my clutch decided to die and started to slip real bad.... i'll order a Exedy Stage 2..
short video of 2. - 3. gear, the clutch gripped but the wheels are spinning in 2. gear Link

man that is a GREAT install, i love how clean you installed everything. Especially with the small space your working with.

I would however try and maybe wrap the manifold and the first 2ft of the charge pipe with some heat wrap. that should help a little in keeping the heat from spreading in the engine bay, and more imporatantly the radiator. Ive never seen an exhaust pipe so close to the radiator, Id be a bit a concerned about the radiator breaking at a track day.

Either way, great job biggrin.gif

I went to the track yesterday and the engine seems to like the boost wink.gif, no bigger problems at all, the oil temp was always below 120C (~250F) and exhaust gas temp peaked at 930C (1700F) @ 6200rpm. The water got a little bit hotter than usual but not too much.
The stock clutch is still in an holds the boost without problems... i'm a little bit astonished about this.

I got a video of the fastest lap.. cam position sucks but i love the engine sound wink.gif Link
I was able to drop the lap times from 2:30 to 2:21 and this with bad tires...

Most of the time the egt is between 1300-1600F but it can rise to 1650-1700 on the long straight..
It usualy peaks at 1630F ... 1690F was the highest i've seen so far.

After about 7k miles the engine still runs great, i did a compression test some weeks ago with ~190psi on all cylinders. The 7A really can take some abuse.. over 200 miles or 15 turns at the circuit without any problems, even at over 90F ambient temperature.
The engine gets 10psi boost at all day driving and 7-9psi at the track, depending on the weather thanks to boost creep at low temps....
Oil consumption is a little bit high with almost 1L/1000km... but it could be worse wink.gif
The fuel consumption is not bad with ~27 mpg overall and 20 mpg at the circuit.

I got a short video from the Autobahn, testing 100-200 km/h acceleration at 10psi Youtube
