OP....any updates?

Just an update.

Build has been delayed due to fabrication of some of the mounts needed for the rads on the car. Tunnel is off this week but it's booked in for mapping next week.

There are 2 sensors in the plenum, one for a gauge in the cockpit and the other for the ecu.

Tuner has done this one a upreved SC and saw Temps of 50C through the sensor. I'm not sure what ambient air was.

He's not entirely sure how far he can go with ecutek, but he plans to wire straight to ecu and use the temp value provided to change advance. He does have another idea if this fails or is unworkable.

So I have some basic info as the car is still being tuned.

Looks positive that ecutek will and is using g the temp gauge from the plenum to advance timings.

As for Temps, I have only a little info. Ambient temp at the moment is around 10°C and the charge temp after the cooler is seeing 50°C under load during tuning. I also have a gauge in the reservoir which seemed to stay around ambient during the tune (testament to how little heat it must remove). SC belt is slipping a little but hopefully end if play tomorrow I'll have some more info.

Fingers crossed ;)

+1 :iagree:

I never thought of doing that. Good idea to see how your heat soak it taking hold. It should rise when the hood is down. Crazy that it isn't getting warm after that air is going past it. That little manifold cooler just cant pull out the heat.

I looked at a video the tuner did during the tune and it does actually raise.

(Rough temps from memory)

Tick over
ambient 12.8C - water reservoir WR)
plenum 22C

Load
Plenum temps raise gradually to 35C@ full chat (gauge temp), ECU temp reads 45C (faster sensor)
During this the WR stays @12.8C until around 6000rpm and then I saw it raise steadily (12.9C, 13C, 13.1C) over the rest of the rpm range (say 3-4 seconds).

I found this quite encouraging. Real test will be the road test with the hood down and the final test the tuner does on the rollers with the hood down.

So with the ECU reading temps from the plenum and with the knock sensor detection enabled (throws a EML if detected) I'm hooping it wont self implode :smile:.

Figures, hit 470bhp but turned back a little to 452bhp.

I have the car back now and this morning attempted to video the temps on a run to work.

It seemed that every car was on the road and I was unable to really get any deceit footage (7.5 mins of nothing much lol and I sound really bad on video). I will of course attempt again.

I may attach just to share the pain though.........

Crap video but here you go. Terrible I know!

Thnx for the vid and sharing Rep points given. ...good to see the results....temps rise quick at WOT but ur recovery is pretty quick too....Curious to see how the temps will hold when being driven hard for an extended period.

Its working well !

That's the plan for the next video.

Well. I guess your motor is safe on a cold day when not in boost with the w2a..lol.. Cool gauge setup though.

Need those wot pulls to make sense of this monitoring.

You going to a track for that?

Can't get to track in the near future. I will find an alternative and post some results on Monday evening.

I had a little play this morning on the way to work as we have some fairly quiet country roads.

Excuse some of the expletives as I thought I was going a rally cross at one point.


You can see that the temps rise very quick. Its know wonder these motors blow using the MAFs pre charge.

I really need to get to a track now and see how it holds up after 20 mins.

I also took a picture of the temps after 1 hour of the car sitting in the carpark (ignition off), they do drop fairly quick though, but then I've added a fan to the back of the Frozenboost to pull air whilst stationary.

Great Vid...Rep points given once again ....Those back roads are rough man.....In the beginning of the vid ur car ate it hard on a bump..... I also said "F*** Me" when u hit it....:rofl2:

On ur run it looks like 44*C was as high as it got in the Plenum....ur temp after sitting one hour in traffic is crazy too.....but ur recovery time is quick as well....are these the highest you've seen the temps under full load and when in traffic?

Haha, I'm on standard suspension and I think that there is a lot more weight upfront with the A2W, so I need to get some stiffer springs at least.

That's the highest I've seen it, which was about the same during tunning. I need to do some extended testing (20 mins) to really get a feel for it.

The pic was after 1hr in the car park ignition off, so full engine soak. In traffic ive not see it reach above 30*C. Ive edited the post to make this clear.

I'm really glad I put the gauge in and even more so that the ECU uses that temp for advancement.

Thanks for Your Video

This brings more light and information into the dark:tiphat:

It's going to be interesting to compare this data to Swiss's when his car is done.

blobbish, I know you upgraded to the Frozenboost, but are you on the stock Stillen pump or did you upgrade like Swiss?

I'm on the stock pump. I'm interested in seeing what benefits Swiss can get from it, but looking at the video you can see the water temps climbing as the intake temps rise and once you step off of WOT they drop quickly. So the current pump seems to be working well.

My only concern would be the worry that flow would be so high that the efficiency of the rad would be compromised. I'm not sure if Swiss is monitoring water temps.

I don't know why the water temp isn't heating up like the intake but we checked my water many time after coming of the track and it was very hot, sorry I don't remember the temp. I guess it must be the length of time at WOT and hotter weather so I'm curios to see if this changes in the summer.

I think that's the point. The water does take some of the heat away but in reality the cooler inside the plenum just isn't big or efficient enough.

As for plenum temps this has to be due to compression surely?

I'm figuring your right JWILLIS. ...length of WOT and weather conditions will have an effect......look at Sebs vid with the one tune in which AIT'S came I at 200*F at WOT on a dyno pull....that was with a Frozenboost Heat exchanger

So today was a big day for the car. First track day since fitting the SC. No video though as no suction fixings allowed. :(

Temps outside were 13c, water tank reading 18c and plenum temps 23c at beginning. The track has lots of twisters with three straight so I knew the car would get a good thrashing.

So first session I was a little apprehensive having read all of the issues, but truth be told everything was solid, water tank temps rose upto 24c with the plenum temps rising to 47c when on WOT. These fell quickly on a cool down lap.

I did find that starting the car after a period of cool down 30mins would see empty of heat soak but withing a few mins of the car starting allowing the water to flow and fans on the w2a radiator the temps dropped to below 30c in the plenum.

By the afternoon I watched the temps where I could and they were steady around 47-51c plenum and around 28-30c in the water tank whilst on track. The car has been set to go into limp mode should the plenum temps raised to 60c and they were now are close to that and they dropped quickly once I backed off.

All in all a positive and with the outside temp raising to 16c the temps were manageable as I've seen air temps on a standard turbo run upto 50c, which leads me to believe that a good chunk of the heat is from compression.

At no point did the car feel like it was loosing power, so not sure what all you guys are complaining about :)

It appears based on ur research and experiment that if ur not going for any more upgrades (Pulley/Impeller) than the A2W with the upgraded Frozenboost Heat exchanger is suffice with atmospheric temps between 55*F-61*F (13-16 *C). I wonder how this would hold up in warmer weather?

I have a pulley upgrade on my SC. To be fair in 30c air temps I'm not so sure that a2a will hold up any better.

I have other track days booked and will see how it holds up then.

So your stating that the intercooler in your manifold is just as efficient as the massive one that you could mount in the front of a car?
