Never seen that trick with the thermostat, let us know how it goes

Will do bud. Although ive changed so much i couldnt point to it actually doing anything lol
Apparently its common on the rover Kseries engines as thermal shock is what kills the headgaskets(apprently)
 
Nice build man. How you finding the chassis having that power ATM?

Do you struggle for traction at all around the circuit?
Car looks seriously quick!
 
On the road it just lights the wheels up in 3rd, absolutely no chance of any grip until 4th but on the track amazingly it pulls absolutely fine in 3rd unless theres a dip or bump in the track then that will set abit of wheelspin off. Tbh it could do with more power for trackwork imo lol
 
So update.
Went back to brands, although the cooling was much better it was far from ideal, i can now get 3 hot laps in a row and then the coolant would hit 100c so i would then back off for 2 laps and go again.
This led to far more seat time and as a result another new PB! same boost level of 1.2bar but i shaved 0.8 secs of the last PB so thats good.
New PB stands at 54.3, although that would be good enough to put me 9th in UK Time Attack (for the FWD class) the cars got more in it as it stands, id say closer to a 53.5 without changing anything.
Heres the video, 1st lap a 54.3 then the 2nd lap is 54.4

I know where i need to be quicker/more committed so the aim is to nail those areas next time out and hopefully take another PB.
We didnt leave brands unscathed though, ive had a sticky rear brake caliper for awhile now, this finally caught up with me as i boiled the fluid in thay corner late in the day, the cooling is still an issue also.
So this week ive replaced both rear calipers with refurbished ones, replaced all the brake fluid, new spark plugs and engine oil as they where well over due.


Now onto my cooling issue, thinking logically(well trying to atleast) i can only think of 3 things that could cause this issue
Poor airflow
Poor coolant flow
Poorly engine

After the last round of tests im not willing to throw the towel in on the engine, it pulls well(as you can see) compression is good, doesnt use water or over pressurise the system, so park that for now.
This leaves me airflow or coolant flow. now my radiator, although large isnt the best quality, is a twin pass radiator but its only a single core. This means that it cant flow as much coolant through it and its got to squeeze all the coolant through the rad one way, then back the other way. Youd think that the coolant having to travel the length of the rad twice would be a good thing right? Well not if the coolant flow slows down too much....
So ive gone baller style(more accurately desperate style) and bought a rywire tuck radiator, these radiators are the same size as my current rad, still twin pass but they are dual core vs my rads single core. Im hoping this will allow somewhere near twice the coolant flow through the rad and thus fix my problem.
As ever, time will tell!
 
Looking very quick Jesse.

My friend had similar issues on track, it's not quite an ek9 turbo but it's a serious built fiesta running full FRP running gear on a stock 1.7 FRP engine.

Fresh engine, never burns oil or uses water, but after a couple hot laps water and oil temp would rise and oil pressure would drop.

So he customised a Dam effect in front of the radiator so the air flow could only travel one way, its
Much like the Mk2 Focus RS intercoolers where the radiator has panels either side to force air through the radiator.

It made a massive improvement for him.

This is something else i can look into, in hiensight i should have tried to better the airflow first rather than spending out on the rad but its done now and the car can only benifit from it, my wallet not so much.
Ill make some air guides to stop the air travelling around the rad pack once the rad arrives. I dont really want to keep pushing on with these issues so may aswell carpet bomb the problem lol
 
^so as we can see ive hit some kind of image hosting limit with photobucket and theyve locked all my photos on this thread, the crooks want 400USD to reopen all the pictures(like ****) so does anyone know how to share photos on here through a different host?

Yeh man it's really easy I'll walk you through it....
Press upload a file, select a Photo, it will then appear below the message box. Then where ever you want the picture to be, place the cursor in the message box. And then click full image next too the picture

That's it! If uploading multiple photos you can upload them all at the same time.

No need for photo bucket! This is far quicker and easier!
Ek9.org FTW
 
400USD!!!!!! WTF
Sounds like some scam hack thing you ear on the news.

I just use the upload section as stated above, only issue it has a size limit so you may need to go into paint to reduce the size of the file like I do. Think the limit is 3MB but my phone and GOPRO average 4MB
 
So found some bad news yesterday, whilst checking the intake system for boost leaks(there where lots) i found a leak from the compressor housing. Thinking "ah its just a seals gone on it" i take the compressor housing off.
Turns out the squealy/whiney noise in the last video was due to this and not a boost leak

I know exactly how this happened and its all my own fault.
Basically whilst diagnosing another issue i left my filter off for a quick run down the motorway, hit boost and the turbo has pulled a vacuum line through itself and thats completely destroyed the compressor wheel!
Now i obviously need to fix this, options i can see are rebuild as is, upgrade the compressor to the next size up(71mm instead of 67mm) which should see the car hit that 500 barrier.
Upgrade the whole unit to a gtx30 or similar.
 
Raided piggy bank and am going for a larger turbine wheel aswell now.
So my turbo will essentially be a gtx2971r now instead of gtx2867r.
 
Right so ive made a start on a list of jobs to get the car back on the track. Im at a stag do/trackday at snetterton on the 24th of july and its going to be tight, esp for the turbo to be back in time for me to fit it and put a trackable map on the car.

First up is making up a 3" downpipe to replace the 2.5" one and to fit my new turbine housing. Ive been meaning to do this for ages so now is the time for it to be done.
Ive always struggled with welding and no matter how much i practice i cant seem to make a "nice" looking weld. My welds never fail or leak they just look ****, not to worry, my sins will be masked with heat wrap!

Next up the radiator, rywire tuck rad in the larger 24x12 size.
As you can see its far better built than my old radiator, a good bit heavier aswell!

70mm thick! Combined with my intercooler at 90mm thick im not left with much room to mount the oil cooler.
I cant use the back of the rad like i had before because this radiator has a built in fan shroud(not sure i approve of this yet)
Infront of the intercooler would surely cause some intake temp issues, no room in the front of either arch due to boost piping.
So ive had to think outside the box, ive not finished mounting it yet so no pictures but it will involve chopping out more of the front bumper and the crash bar.
So what started as a simple rad swap and turbo rebuild has taken abit of a turn lol
 
Alittle more progress today, its pretty slow going though.
"Welded" a lambda sensor bung into the new downpipe, also put some left over exhaust wrap on it. Ordered some more to finish it off as it will sit fairly close to my splitter.
Also finally got the radiator in! Its mounting via the sides. I didnt like the idea of welding the supplied mounts straight to the car or even solid bolting them so i made up a rubber mount setup for them, the radiator would then rock alittle on these mounts so i welded some radiator stays into the slam panel, ill get some sticky pads for them so they dont knock against the rad.

I left the oil cooler for today, i spent a fair bit of time mocking up some radiator ducts to stop the air travelling around the radiator, abit tricky because the rad sits so far forward and its all super tight in the front of this car
 
Looks a bit tight in there dude lol!

Yeah the rad defo fills the space! If im being picky it could be like 3" longer but its as tall as it can be really.
Im confident this along with the ducting will fix the coolant forever!
