All tidied up now The controller is behind the passenger seat The FAV will be behind the drivers seat behind the speaker panel and Which just leaves me to tap the manifold and install. 2 injectors either side of the manifold

[CHILL Gone DUTCH]

Just to keep the thread up to date Wi is coming to the end Well the putting in bit anyway and have a oulton TD on the 4th next month to give it a good testing and fine tune While inlet and charger is off Going to do oil and filter change and give the clutch a bleed And few little bits before it goes all back together

Few pics of recent activity

The inlet and laminovas are very clean since they last came out more than two years ago so Pcv is doing well

Inside inlet to manifold

Good progress. Looking forward to seeing the results as I'm sure you are! The PCV seems to be working great. Looks like you've got the best solution to this issue.

the water is now being injected in to the manifold, the early signs  are looking 

 

i think the water injection will be ongoing and trying different ratios 

 

the question is, is it better to inject asleast water as possible to have the desired effect or better to inject more and keep the exhaust temps low also, 

 

 

 

[CHILL Gone DUTCH]

results 

water switched on at around 150 on time stamp 

and gave it the beans just after to get the water injection active as it dosent kick in at the moment at around 31% duty cycle of the injector 

 

 

so early signs are good 

[CHILL Gone DUTCH]

will be going oulton Park on the 4th october and will do a few laps and get the intake temps up and the switch the water on and see how quickly it can recover the temps

When i first put the water injection on over the original map the car was not keen and dropped power in the software to around 330 HP
After speaking to others recently on the water injection thread about the burn rate being significantly slower afternoon increasing the ignition by 1.5 % the power is roughly where it was without the water injection



So target today will be to work on the ignition more to try and smooth things out and see what happens and achievable with the 100% water

I will also look further in playing with the ADR

[CHILL Gone DUTCH]

lol just read back above 

i meant 1.5 degrees of ignition not 1.5 % and AFR not ADR

[CHILL Gone DUTCH]

well im still at it and finding quite hard to find consistency around the water injection

i still have more knock with the water than my old map without water also my old map feels so much better and is producing more power (& heat )

 

 

 

i may be really underestimating how much of  a slow burn the water is producing and may need even more ignition in there, has anyone else had any expirience with how much ignition they have added to get the water injection to burn correctly ??

I suspect you are discovering why engineers have been using mixes of around 50/50 water/methanol. The methanol has a fairly high calorific value (about 90% of petrol roughly) which still also helps cools the charge and it's higher octane allows for some ignition advance without worrying so much about detonation.

Chill have you gone through the process of reducing the amount of water injected until you see temps starting to raise? Or is this a constant that is set by the injector size? Just thinking you may be injecting too much water and no amount of ignition advance will get your power back.

[siztenboots]

would this change the dynamic compression , is there a risk of hydrolock

Yes ive always thought i was on the brink of the water being effected i did reduce it and the cooling effect was quite poor so imo im already using the least amount, peter is injecting a lot more than me as is acidpopstar (acids car does worry me from what ive found out over the last few weeks ) 

[CHILL Gone DUTCH]

Ive reduced the knock at wot considerably today  but still have a little which i would like to get rid off

gone from this 

 

 

to this with some 3-6 degrees of extra igniton

 

 

and the car feels a lot better now and a lot stronger but adding more ignition or lowering ignition is not helping

Chill I would try changing the AFR just a few points to see how it affects things
