55k cooling upgrade

The instrument cluster display would be interesting, you could also look at a away to use the aux input of the Comand unit (if you have a TV unit installed) to display your data from your data logging app.

I can check what the map does for the fixed SC pulley to see if it uses the smaller TB to release boost as a safety measure as that's the only way I could think you could instantly reduce boost but it would be good to get some data on a car without a pulley first.

The 103C is a bit of a red herring as you obviously had a problem either with your pump, heat exchanger or air in the system on your stock system.

10C I presume is the temp the water in the tank has been reduced to when not under load, that's like driving round with the box just filled with ice ALL the time ready for a blast

The interesting part will be how quick the temps rise, peak temps and recovery. Can you also log the Boost at the same time it should then be possible to calculate the effects of increasing the boost through a pulley change.

You probably won't notice it now that summer is over but interested to see how your AC in the cabin copes, I don't think you will have an issue as our summers don't work the AC that hard. Only ones that seem to have an issue are those that live in hotter climates, some of then are looking at adding a higher capacity AC compressor to compensate.

Its not really a red herring as its the starting point of the project, the first graph does exactly what it says on the tin i.e. shows forum members what happens when you have as you describe above.

Stage one showed a massive drop given that the HE along with a pump was exchanged.

I expect stage 2 to show much improved gains.

Regarding the FSP there is no other safeguard to your engine other than monitoring IAT's and turning the engine off should you get elevated levels, I believe Eurocharged used a bone stock E55 with over 160k on the clock for testing.

Ice melts as well

That's the plan.

I understand in relation to how your car was but stage 1 is probably a better starting point as its difficult to compare the performance improvement with something that was broken.

As for the FSP rather than shutting it down probably best to get a data logger that is wired with an output to some kind of blow off valve, that way you could set the parameters and if exceeded it can send voltage to release the boost while you can back off the throttle.

I agree with your comments, at least forum members can see the difference, I would have liked and the plan was to replace just the pump data log and start at that point, but the HE was shot and it was decided to change out which in itself is an upgrade i.e. size.

The FSP does interest me reading on the site across the pond only a few have fitted it with very positive reviews so far, agree with the blow off valve idea just pushes up the costs though, with boost always on from what has been written this mod changes the car completely.

The FSP that replaces the stock pulley size for size interests me, there is an increase in IAT's as its on all the time, increasing temps the more aggressive FSP sizes you go.

I doubt the IAT's will climb that much, sure they will be slightly higher at cruise speed but once under load it will even out anyway.

Plus your going to have KC with an insane starting point!

Going you know you want to

We have just finished the final touches. It just needs some data logging to see if it works well. Its taken its time to get it right.

 

[simon1966]

Looking forward to seeing the results Olly.

 

[Ginger55k]

So am I

Will have to wait till Friday, you will all appreciate Olly is the best, perfection takes time.

Thanks to the PCS crew.

hi |Simon did you get the kiwi 2 device..... I have tried Bluetooth module but hit and miss... but saw you recommendation and seeing if it connects up fine

Hi Kalvin

Yes I got the kiwi 2, but mine is the wifi version for iphone.

It's easy to connect and works fine. It seems a neat bit of kit, but to be honest I haven't really managed to do much logging as yet. I did have a couple of goes but its hard to find decent stretches of road to do repeated long hard pulls and then when I did I didn't have all the correct bloody things selected to log!? I have to say I'm a real technophobe on anything like this or computer based so it's just me being thick, not the fault of the kiwi 2.

I actually went to see Paul (Savman) and Andy today and they did some logging for me. Paul is going to send me the graphs but all looked pretty good with IAT's. Timing could be improved a bit so Paul is going to look into that for me.

BTW - saw your car, very nice!!

GREAT... I will probably ordering the version you have... Bluetooth OBD2 works on Skoda etc. but not registering on the E55.. thanks for compliment! cars in garage with Andy at PCD... trying to get the supercharger pulley mod done with remap in collaboration with the modded crank already fitted... but initial observations seem to convey fuelling and cooling shortfalls..so will have better idea tomorrow on which way to go

Andy showed me the crank pulley you have fitted, it makes my stock one look a bit inadequate! I have to say I wouldn't mind a slightly bigger crank pulley to work with my s/c pulley but not to that extent.

Both Andy and Paul said your car pulls really hard

Hi Simon... when did you see the car? in last few days?

 

[simon1966]

Hi Simon... when did you see the car? in last few days?

Yes - I went there today. Andy was busy getting data off it.

I'm sure both Andy and Paul will be able to advise best way forward for you. They know their stuff.

Hi simon saw Andy and gather you going to get some mods done.... I think i may now have to get larger injectors, cooling system sorted now to accommodate the supercharger mod an remap.... Good thing is the wife and kids wont be around when 'hopefully' i get this done... This side of Xmas... But makes sense to get everything done in one go i suppose rather than repeated trips etc

Update: Picked up car from Olly today and data logged on way home.

Olly and the boys had already tested the car with star connected and could see the IAT's rapidly falling between each WOT burst, Olly's description "it feels like it already has a pulley and remap".

Now thats what i wanted to hear

Its taken a little while to dial in the system and we decided to remove the second pump.

The tank came out again to have further mods carried out within, we felt that the internal tank spray bar was restricting flows too much and a baffle plate was fitted while the tank was open, further work was carried out to the plumbing to aid improved flows.

The IC pump is configured as stock so operates as normal from the ECU.

So after all this work Olly tells me he has other ideas to improve the system even more Olly stop it please, I need to enjoy it for a while.

So the results are on average 10 degrees lower than previous and that's against the new pump and upgrade to a Eurocharged HE, so very impressive, but the best bit is those numbers the temps drop very rapid between pulls, wonder what its like with the pump on all the time?

Olly you've got me at it now.

Sorry I'm probably just being a bit thick but I'm not sure I really understand the graph and it's also quite difficult to read! I can see it looks better than your previous graph, but what is being recorded on the horizontal axis? I assume its time in seconds but....?

From your peak IAT what is your recovery time and temp fall?
