Dont be so fucking lazy! Merry Christmas!

 

Very good news to hear

 

Nice updates

 

Christmas is done so on Monday/Tuesday will see if i can pick up the parts from Mark & then get to Vibration Free before the weekend. Need to remove the Loom from the car for the Dyno so that's first thing on the agenda for 2014.

 

I for one can not wait to see this car run again, was looking on YouTube at vids of the old spec, brutal!

 

Even the best laid plans fall apart forgot that i was to visit my brother this week more of a priority than the car. Still next week will be fine .

 

Still not had time to get to Vibration Free cant understand how you guys have time to work .
Did do something today. We are using a new flywheel on the latest build & it turns out to be different threads to attach the clutch so i went to Apex fasteners to get suitable screws.

Tomorrow looks a likely day if the weather is not bad to run over to Marks to pick up the bits & then take to VF. At least the Merc will get a good run out but i dont like getting it wet so will see what tomorrow brings.

 

Dust the audi off if you don't like getting the merc wet rod

 

Been to Marks today but had to help my Son in the morning so no time to get to Vibration Free . They are at Autosport tomorrow so ive arranged to meet Steve on Friday.
Ive a lot of questions to ask about other parts that may require balancing not just the normal Crank, Rods, Pistons & Cams. Also advice on mods to the front pulley & dry sump.
The front chassis cross member was moved forwards to fit my Intercooler & with very thin fans we may have room for a balancer on the front pulley to compliment the balancer also fitted to a 'secret squirrel' location on the engine. If it improves things by 10% I will pay to have it developed.

Lets hope i get all the answers on Friday its another step along the way. This is my last fling lads so no stone being left unturned.

 

That cars like new scared to breath on it . I went in the Rover today but lets hope its dry on Friday I love the Merc its my type of car built for ageing gents with just a hint of performance if you need it.

 

Finally delivered the parts to Vibration Free today .
Steve is aware what we are doing to this engine so I asked if a Balancer on the front pulley would help compliment other mods. His view was the existing mods would probably cure the vibration probs but there were other benefits if the front balancer was done correctly. Could buy one from the States & mod it or design one from scratch to be correct for this application. Its more expensive but i gave the go ahead to design what we require. It will take around 8 weeks so a delay but will be worth the wait.
Forgot to ask his views on other parts but ive time to spare now.

Just thought of the fact I now require a 4 bar boost gauge can get a 52mm one but its too small any ideas. With the 9180 at the boost levels we will be using i need to keep an eye on Turbo speed so im looking at that. Found one reading up to 200k rpm & an interface to get readings from the EFR sensor.
Before you ask im out of suitable analog inputs on the SM4 so unless i lose an existing function im stuck with other means of keeping a check on Turbo Speed.
Think Mark would like me to change ECU's at this point but its a lot of aggro to gain one more input. I could probably lose Launch Control.

 

Will you be posting photos of the engine build? I'd be interested to see the mods you are doing?

 

I would think so at the mo its just a lot of bits. One of the mods will not be shown at this stage. The company agrees we will not make it public until its proved to work. That means holding together at circa 1000bhp & completing a Topspeed run using massive Power. It works in Aero engines is all I will say at the mo.

 

Understandable You engine is pretty much cutting edge YB, so it'd be nice to have a nosey

 

There will be a couple of parts that will not be shown as we hope this fixes the block problem this is very diff from what other have done to try and fix it,
There will be times I am sure I will censur Rod.

Mark

 

Hah...

 

Is mapping around the ECU boost limit going to always be a factor in the back of yours/Marks mind. After all this is the final time and your surely going to always think 'what if' if the current setup ECU doesnt provide the goods on the day. I know its a case of where do you stop but new engine, new goals deserves that new ECU .
Is it really that much aggro to change it? Sounds quite a radical change none the less going by your standards.

 

Does it need to be like ?
Or can it be like this one?

 

We can use a external map sensor and there is a chance we will use it,
I have tried to push Rod to my new Ecu but he is spending enough as it is.

Mark

 

Mark

I can free up HSI 1 if i lose flat shift which has never been used. Can this be used for Turbo Speed.

 

It is the correct input I will get the sensor spec to check it is fine.

Mark

 

I have spent the last few hours drawing up a Circuit Diagram for this new ECU.
Im not even sure Mark is prepared to name the company that makes it yet perhaps Mark can answer that.
It certainly takes all the problems away it has 44 inputs/outputs the SM4 unit had 14.
I going to write a book ' The stupid amount of money it cost to go from 840bhp to 1000bhp' Mark was shocked he was out by about 50%.

If i go for it i have an sm4 for sale thats good for 99.99% of all applications

 

I can't name it but you can.

Mark

 

OK

Mark is suggesting I fit an Emtron KV8.

http://emtronaustralia.com.au

 

Why is it called project queen? lol

 

Finding the vibration stuff very interesting Rod - it's a real black art!

 

The gt4202 will be used on the Dyno only, a EFR 9180 being fitted in the car.
Hence its a 'Dyno Queen' engine the gt4202 cant be compared to a EFR for response for a road engine but it will crank out the Power. Targets are 1000bhp for the 42 & 900bhp for the EFR which is more than enough to set an impressive Topspeed around 212mph. If we want more we have a 200 shot of Nitous to call on.

 

Have you decided to go for it Rod?
Changing ECU for 'one run' is crazy for most but not in this case IMO.
Oh I also keep thinking about the bonnet tips you bent at 200mph.
Any pics?

 

Have I decided well its more likely I will than i wont .

Done a bit of prep work diagrams for Emtron Loom & its interface to existing car Loom & my pin allocation for functions. Autronic & Vipec im well into but never seen this ECU before so I think this is OK.

 

This Ecu is more modern and has closed loop knock and lambda and can scratch Rods arse if needed also.

Mark

 

Looks good only need to move the temp sensors to ANV 7 onwards.

Mark

 

At Rod's age a bit of arse scratching is probably useful.

 

Closed loop knock control is very difficult to setup, but once done would be great to have

 

Agree ive now read the Spec 100% instead of 90% .

Ive moved WTS & ATS to ANV 7&8 & TPS to ANV 1 only concern is Dry Sump sensor it needs to switch engine off will it go to ANV2 or 9.
Cheers Rod

 

Hello Rod, do you have access to your plenum? Could you measure the width and length of the slot between the lower and upper plenum?
Something like 30mm x 300mm ... ?

 

No it was delivered to Mark months ago its 42 miles away so ive no access. Mark scans this thread so he may be able to answer.

 

Subscribing to this interesting thread

 

The decision is made im going to purchase a Emtron KV8. Have an offer on the SM4 before i had chance to put it on sale.
Need the loom out of the car now to make an Emtron copy & to sell with the SM4.

 

I hope it was John as he asked me for it.

Mark

 

Not many sell there ECU twice on the first day before its advertised .
