Yes its my car .... unfortunately the engine blew recently (due to a bad tune), but it will be back again sometime in 2014 after it is rebuilt and tuned by someone else.

Power will still be around 500BHP at the wheels.....

What exactly was wrong with the tune? Too lean?

The engine suffered Detonation while on track on a warm day, so I think the issue was a lack of ignition correction in relation to the temperature... I cant be 100% sure as I wasnt logging data at the time. Fuel is fine - the  AFR is around 11.5 on boost & was so at the time of the problem....
below is the most recent dyno plot.. dotted line is Boost. Blue AFR, Green Torque(lb/ft) & orange/red power (BHP)

I have had the map looked at by a couple of other tuners (one of which will be doing the next tune) & both have commented that  there is a few things that they would consider to be wrong or that should be done differently  :rolleyes:

Not much progress, been saving some money so I could order the new pistons., which I have just ordered.

CP Pistons with a 3cc bigger dish than the last pistons to lower the compression slightly from 8.6to 8.3.

What's the main advantage of the lower compression? Sligtly lower temperature?
Titel: Re: Geen GTA, wel GTA motor
Bericht door: turbonutter op 8 februari 2014, 17:16:06
Given that the first Build of this engine blew a head gasket due to detonation and the fact that I needed new pistons, I went with lower CR to move further away from the detonation point, yes lower CR will give lower temps all other things equal.
The main point is not to increase the compression ratio. I am using Total seal rings this time & these can give slightly higher compression. As well as the heads being skimmed which will also increase the CR slightly.
I am changing engine tuner this time and he also suggested a slightly lower CR, as having a large turbo the boost builds quickly anyway and this should help smooth the delivery..
Pistons will also have Calico coating on the skirts - no crown coating though, as it isnt really necessary for my engine.

Working away has its advantage sometimes.
I am in the USA next week & collect my new ECU and accessories. Its an american ECU & getting it here saves me EUR1000!

This is the ECU an AEM Infinity 8, which as well as running the engine will run the DBW that I couldnt run previously, has dual Knock Inputs, Traction control & can log 100 channels at upto 1khz.
I also got a 4 Channel EGT thermocouple amp,  and thermocouples, 2 lambda sensors & connector kit, & 3x dash 12 position switches.

its a nice little late christmas present!

Any particular reason you chose that AEM Infinity ECU?
Titel: Re: Geen GTA, wel GTA motor
Bericht door: turbonutter op 27 maart 2014, 18:37:52
I wanted to add more inputs to the Haltech, so I could get aditional logging & also planned to add a race logic traction control. The aditional inputs would have required an add on IO box, and to do the logging properly with the haltech, I would have needed a small tablet PC running windows, so in the end it made sense to change to an ecu that would do everything i needed.
I will be using someone new for this tune and we looked at various ECU's. The new guy is concerned with having very good boost control, to the point where he likes to have an ecu that allows the boost control to be able to react predictively. i.e. to predict and then to make changes rather than to wait until a condition occurs and then react after it has happened. If you get what I mean.
This was one of the ECU's he is happy to work with, that will do this, the other being Pectel, which is a bit expensive! The AEM is also supposed to have very good traction control.

I dont think I have ever had a standard ECU, my first car had webber Alpha, this one had Haltech & now AEM.....

First of all, welcome!

Second: Lovely job! Cost a damn fortune for sure....

Yeah, knock, before you know it,... and pistons fuse like an acetylene torch. Your running on/over design thermal load, great stuff!

Lowering compression ratio is absolutely critical with what you're playing with....

What are you charging? 1.5 - 1.7 bar? Maybe even more??

You use race head gaskets I assume? Cannot be ordered in EU, have to be especially made to order....

In your case an absolute must as well, standard head gaskets won't do at all.

Very impressive!

Pity you blew your engine....
Your crankshaft is still usable?

I read yanko's post on Alfaowner a few days ago, he's also going AEM, but piggy back ECU, you're using the full version, interesting...

Yeah, trimming the head an extra 0,5mm helps raise compression somewhat, but in your case the opposite of what you want? Or am I missing something?

I looked everywhere for GTA pistons manufacturers, Mahler doesn't even have them on catalogue....where/how did you find them?

Looks great!
Titel: Re: Geen GTA, wel GTA motor
Bericht door: turbonutter op 3 april 2014, 03:06:05
Thanks for the welcome.... & yes a small fortune!

The Engine was running around 8.6:1 when the head gasket blew, new pistons will drop the CR to about 8.3 or 8.4.
The head is only being skimmed to remove the damage from the detonation. It will be the lightest skim possible to remove the damage & this has already been taken into account when ordering the new pistons.
The pistons are custom made to order. I use performance unlimited in the UK. They scanned my piston & then designed the new pistons to the compression ratio I wanted. They have designed various pistons for the alfa engine, but not sure about High Compression ones for teh GTA, but they should be able to do whatever is needed. They have the pistons made by either CP or JE pistons in the USA. Takes about 6 weeks & £1000.

I was running 1.2-1.3 bar boost to get 515WHP, so nothing too extreem. The only damage to the engine was the pistons, so not to bad. Everything else is reusable.

I was using Spesso Racing Head gaskets, which are available in europe, the only issue is the price - £400 for a pair & that was a discount. For the rebuild I will be using a stock gasket, but a good quality one (victor reinz). I have talked with a few people and all agree that the stock gasket will be fine so long as the engine is tuned propperly & there is no detonation. But on the advice from a couple of people I will be having the liners "o-ringed" to improve the gasket sealing.

Bericht door: Masso op 3 april 2014, 10:36:09
You mean on top? Or special o-rings instead of the original ones which seal the cylinders in their seats?

Read your post, interesting stuff Neill. Really nice.

Seems to me that the Stratos has a very short wheel base and has tremendous under steer? With this power you must aim & pray in a corner?

I would love to take a few corners with a fun factory like this one!

Good call on the 164 gearbox, the 24v Busso gearboxes apparently cannot handle more than approx 430 - 450Nm, which is a damned shame, a six speed would do nicely in your Stratos.

I was admiring your custom flywheel, beautiful work of art...

Stainless Steel Wire O-rings on top of the Liner to bite into the head gasket. My first Car with a twin turbo 12V Alfa, I just had grooves in the top of the liner for the gasket to deform into, which is a similar principle, only the o-rings are more positive.

Yes its a short & wide car, which changes direction very quickly, I have never really had an issue with Under steer, more of an oversteer problem & trying to prevent the car going backwards. There are a couple of videos on my site that demonstrate this...

Its for sure a lot of fun...

The busso gearbox can be modified with a lot of machining and steel spectacle pieces inserted to hold the bearings together, but its expensive, hence I opted for the Toyota box.

The flywheel is really nice and only 3.2kg - not expensive either. I have a second one that was made with the crankshaft bolt pattern wrong. The offset hole was offset in the wrong direction!

Those are now away again to be matched to the weight of the last pistons - that way I can avoid having to rebalance the whole engine as an assembly.

No Progress on the engine.... Well I have now had the liners machined and the Stainless o-rings installed & the pistons are back from balancing, they now all weigh the same as the first set of pistons, so there will be no need to rebalance the whole engine assembly :)
I havent started the rebuild, as I want to finish the other jobs on the car first. I have had a mock loom for the engine made from string & my new Tuner is making up the loom for the new ECU.

I havent been idle, & have finished the wiring changes that I need to do & I have mounted sensors for traction control, as well as remaking various water pipes for the engine and charge cooler.

The Gear Lever I have fabricated is finaly finished and back from the Anodisers & Powder Coaters......................

Its all installed now as far as I can, engine is in the car and I have just fitted an elbow in place of the turbo so that we can get a decent N/A map first, without having to worry about the turbo control etc.

Today I will be checking out the sensors on the engine, then I am away for a week on a course, after that my tuner will be doing a final check & terminating the last of the sensors & we will be starting it up....

OK So finally got the Car on the Rolling road this week.. apart from the fuel pump fuse blowing when we first started the car, the session went pretty well...

Everything worked fine  and we ended up with 197 WHP , so probably 220BHP, which isnt too bad for an 8.3:1 CR engine with a far from ideal exhaust & one that is sucking through the intercooler.

The Flames in that Video were wuite mild, compared to one of the runs made giving it everything up and down the gears :)

Unfortunately I am away at work again until April, but the turbo will be going back on then :)

Ok so I was home in May & June, but for various reasons didnt manage to get the turbo on the car until the beginning of June & finally on the Rolling road on the 15th 2 days before  I was due on track.
The new ECU worked well, there was hardly any changes needed to teh fuel/ignition maps after adding the turbo, the ECU internal corrections for boost sorted it all out.
I had changed the Waste Gate spring to a 0.4 bar spring (it was 1bar before) so that I could get a bigger range of boost control. Th etarget for the session was a max of 1 bar & minimu 0.5 bar, but we struggled to get over 0.9 bar and also with consistency, So I need to look at a different boost control set up before the next session. Anyway on the rollers it  made 475BHP with 0.9bar, which was near enough & would have been fine for the track session I had planned.

So happy with the Tune, once back home, I took the car out on the road, It drove well & the first acceleration run it felt like the 500BHP I was used to :)

But after that it started cutting on boost, not every time, but there was the occasional cut :(

Anyway did a few runs out, collecting data, with various engine protection functions disabled to try & find the fault - the last run when I got home & tried to park the car in the Garage, there was no clutch.....!!!! and a track session in 2 days !!!
A quick check when things had cooled down the next morning & I found one of the clutch plates was no longer attached to the gearbox input shaft :(:(:( So that was the track session cancelled as there was no time to get a new clutch & pull th eengine to change it... So that is how the car was left when I came back to work.

bad news, hope you get the clutch installed soon.
Good to see the engine is running again. Keep the news coming, nice reading!

Found the problem with the Clutch - I had fitted the plate closest to the engine the wrong way round, which meant that the spline was only engaged on the tapered part at the end of the shaft & that couldnt take the forces....(https://www.clubalfaromeo.nl/proxy.php?request=http%3A%2F%2Fi1086.photobucket.com%2Falbums%2Fj446%2Fturbonutter_neil%2Fplate.jpg&hash=8bb9a7de15a863f6e455cf4ae1153b0be1d9ace4) (http://s1086.photobucket.com/user/turbonutter_neil/media/plate.jpg.html)

Flywheel is fine as is the gearbox shaft. New clutch is now fitted - the correct way around!

Had a day testing at my local circuit, to set up the traction control & boost control, both are working very well now. Just running 1bar of boost for now, as I want to get some driving done, without having to worry about breaking anything!



Here is the car on track:

When we got to the track, the overrun fuel was causing a huge fireball from the exhaust, but that is now reduced to a reasonable size....

After setting up on the track, I went back to the Rolling Road for a quick power run, with the below results 473BHP & 460lbft
