Turbo Intake Temps

[thetyrant]

Ok now ive sorted my coolant issues ive finally been able to get out and have some fun in the car to see what needs tweaking next, first thing is to see how the Air to Air intercooler copes with my kind of driving on the road initially, not got plans for track use until next month so that will be a harder test for it.

My kit i think is a SP240 kit and the intercooler that came with it i dont think is original TTE IC and possibly slightly larger version of it made by a company called Docking Engineering,  anyone with TTE IC be interested in pictures ans sizes to compare, i was expecting it to really struggle but so far in these cooler temp its coping ok for what it is but will see how it goes with more sustained abuse on track.

Below are some graphs pulled from the datalogs after a fast blast up and down my favorite local road the A686 Melmerby to Harside summit with ambient air temp around 9c today, as you can see on first graph which is the ascent that under normal road use before the climb started i was sat around 17c Intake temp, once abuse starts it climbs upto a peak of 35-36c over the next 6 minutes of abuse but doesnt go any higher at least on this run, not bad really considering IC size and location underneath car on front of gearbox. 

Boost level is actuator pressure at 5psi on this run, it starts to creep up to 6psi from about 5500 rpm, i think if i was running more boost the temps would be a lot different!.  Im staying at this boost for now to save the clutch and also help with temps, plan is 8-10psi once i get clutch in and then i think IC will struggle big time.

Recovery isnt bad either and temps soon drops once you ease off the throttle as you can see as i back off approaching the summit, i stopped and saved the log and started another for the descent which is 2nd graph and while not as brisk on way down and i caught up slow traffic half way down you can see temp drops accordingly.

Normal road driving with burst of boost has be mid to high 20's generally, once weather starts to warm up im sure the limitations of this setup will show more but for now on road at least its doing ok.

Would be good to see what others are getting Intake temps wise on Air to Air and Air to Water Chargecoolers etc

Looks about right. 
I can pull some logs out later
At 10-11psi it does start to peak. But at 5-6psi you can blast that all day long. 
Turbo blanket works.

@thetyrant

With a bit of luck, searching me as a member and a combo of TTE - intercooler or such like should drag up some pics and sizes.
As a random also search BMR radiators as they made me a new one, using the original schwizer (spelling?) as a template.

Edit
How did you sort the coolant issue?

THanks be good to see how it compares with your old setup running more boost.

Im thinking of a turbo blanket to help with underbonnet temps so good to hear they work

Thanks for pictures is that a exact replica of the TTE ?   mine is differnt to that i will see what pics i have.

Coolant issue was just sensor error after all that!...car was running fine just temp sensor reading high.

[thetyrant]

I cant find a good pic of my IC on its own but snipped this out of bigger picture of whole kit, as you can see its very different to your pics Ardent and the TTE design, mine looks to have more core area with smaller tanks as well as different outlet positions, it looks like they made it as big as possible to fit in same location as TTE kit, hopefully @MattPerformance will spot this and be able to confrim more.



This is label on top of it..

Should coolant be an issue - you can always go with the one that MWR use - @Oddshoes has it fitted. It's very very big but seems to enable the PSI levels they run..

I presume thats the rear mounted Air to Air they do on MWR turbo kits ?  if i change mine i think will be going for a water to air chargecooler setup as far more effective but it is more work.

Yup that's the one.
Yes I'm sure Charge coolant is the best way to go, but obviously it is a lot more work and complexity.

I don't know if Dan has pic of the size and placement of the radiator he's running so you can get a feel for the the additional work to fit that vs going charge cooler. But anyway - it's your time and money :-)

[thetyrant]

Indeed its going to be a bit more work/money with a chargecooler but a much better solution for controlling the intake temps, also im hopeful when i go down that route i can make it work in the same location as the current IC as this would save a lot or work with air piping at least also nice and neat tucked away down there, obviously still the water pipework/pump etc to sort out and a bit fiddly working from underneath but once completed should be tidy job i hope.

  Im a bit off that yet though and until i up the boost/sort clutch current setup is ok on road at least, need to get a trackday booked next to see how that pans out, probably start chargecooler shopping after that lol

The SP turbo kit you have was designed to sit in the same location as tte turbo and looked similar in shape but was designed with bigger core. From memory it was 30% more efficient.
Once you factor in High boost and hot day I'm sure it will struggle to cool. But for most fast road use it should be fine for 230/240bhp

Get the updated clutch sorted wind the boost up to 9/10 psi and I'm sure you will be happy

Thats good info thanks, certainly at this boost level its coping ok at least on a cooler ambient temps and once weather warms up we will see what that does.

 I am impressed with how pokey the car is now even at 5psi compared to stock, going up hartside pass on sunday it was so different to last time in stock car as this time i was able to use much less revs and make much faster progress, uphill as we all know is where the stock car really feels it and you need to make it scream and work the gearbox a lot if wanting to make rapid progress, not so much now its effortless

[s12vea]

When you up the boost to 9/10 psi it will be like a different animal again.
The car is soo much more driveable with boost.
They should of all had forced induction from the factory I'm sure it would of made the car more successful worldwide

Yes. Exact replica.
Coolant. Not sure if I'd be annoyed or relieved.

[thetyrant]

Thanks for that and yes i was kind of annoyed it was sensor, but also glad it was mainly just time ive spent on it and im happy rest of system is all good!

Ive just booked on for Croft trackday on 9th march so will see how intercooler copes with that!

[MattPerformance]

The Docking made intercooler was the one I had made for the SP forced induction packages (Lotus and MR2). It is c30% bigger in capacity and c50% more efficient in terms of cooling.

[thetyrant]

Thanks Matt good to know    it will be put through its paces properly on monday at Croft weather permitting

Thanks Matt good to know    it will be put through its paces properly on monday at Croft weather permitting

Where is the location of this IC? Same like TTE?

[s12vea]

Yes same location

Yes as above mounts down in front of gearbox like the TTE
