Jesse888 Forged/stroker turbo ek9


So went to snetterton 300.
10laps in, well 11th lap, outer CV on the passenger side seized up. Basically brand new insane 500hp shaft.... not too pleased if im honest, ive abused stock shafts on track the entire time ive had ek9s and never an issue. "upgraded" shafts and they give out within 6months.
Hoping tegiwa will let me swap these junkers for some Mfactory ones or something, thats if they even take them back.
My first ever time at snetterton though, fun track just abit too flat for me, the best corner is bombhole and thats the only corner with any sort of surface change to it.
Fastest of my 10 laps was a 2:19.2. Low boost again, plan was to turn it up later in the day once i got used to the track, car gave up first lol
New rear tyres have given more grip as i expected and straight away i was more confident, the car will still step out but that limit if further now than it was. Really looking forward to cracking some laps of brands hatch with the rear grip!
Heres the snetterton video...

The odd noise when turning left is the rear tyre catching the wheel arch.
 
Also forgot to mention that when the CV failed i was doing a good 100+MPH, the vibrations it caused has put a massive crack in my exhaust manifold so that needs welding back up aswell.
 
Has it actually broken or just seized from lack of lubrication? Do you have any pictures of the inside? My DSS inner cv started knocking so I changed to insane shafts lol. How bad has manifold cracked?
 
We got it realeased but it does still stick onfull lock. It knocks like **** now aswell.
Id send them back if i was you lol
Ill get pics when i take them off
 
See thats almost acceptable. But 6months old?
 
So heres the cv joint.
Obviously i cleaned it out for the pictures, no grease around the hub area so the boot hasnt been leaking.

 
Good effort.

How long have you been running wheel spacers for with these shafts?

How did you know i run spacers?
The whole time. On the road wheels i need 10mm to clear the brakes, on track i use 5mm.
 
Seen a picture.

Not saying it would cause cv to fail but its something to think about, extra loading plus your relying on studs to centre wheel with 10mm spacer.

Ah right. Thought youd had a mister mayagi moment and saw something in the joint lol
Yeah i may be able to get away with no spacers on the track wheels, from a loading perspective id guess the bearing would take the abuse more so than the CV? Worth looking at like you say, along with ride height etc to check shaft angle is ok.
 
Right update on rebuilding the car from the carnage at snetterton.
After afew emails back and forth with tegiwa(supplier of the insane shaft) they sent a new joint out free of charge on next day delivery. So big thanks to tegiwa for sorting that hassle free.

Then came the joy of trying to get the old CV off. The circlip had slid out infront of the splines on the old cv. Meaning no matter how much hammer it got it wasnt going to just pop off. Litrally had to grind through the joint in 5 different places to release it!
Left me with this damage from the circlip

After a tidy up with a file i got the splines somewhat tidy again.


Then the turbo manifold had cracked, im assuming this was from the vibration of the joint breaking causing this. Would be abit of a coincidence if it was to have failed on its own, at the exact same time...

So some work with the welder(prepare yourself!)


Yeah my welding is pretty bad lol it never looks neat but im confident its going to hold, if not then excuse for a new mani setup! ;)

Next the new CV turns up, filled it with some rather expensive millers moly grease(£20 a tub) much more grease like than the stuff that came out! Whilst i was there i took the inner cv off to inspect and replace the grease in that. The grease in the inner CV was much more grease-like than the stuff that ran out of the outer CV that had failed. Which is interesting.

Next thing i decided to do was pull the coilovers off the car for inspection, they are at minimum 6 years old and are 3rd hand with me. Turns out they all adjust fine bar the height adjustment on the drivers rear. Stainless steel damper bodies rule!



Now ive wanted stiffer suspension for alittle while but now was the perfect time to do it.
Not having the surplus cash to go out and buy a set at £8-£900 ive opted to keep my cusco dampers and put the front springs(9kg) on the back(old 6kg) and buy replacement 12.5kg springs from faulkner race springs. Im hoping this will be stiff enough to keep me happy but soft enough for the dampers to control correctly and be drivable on bumpy tracks like the nurburgring.
Heres the front springs mounted on the rear dampers with the old springs next to them for reference. Note the "new" springs are 1" shorter than the "old" rear springs. Not sure if this is going to effect the performance of the damper any?


Fitted that lot today so its a waiting game for the front springs to turn up.



Hoping to get out to brands sometime next month to test it all out. Felt great at snet before it was stopped short.
 
Looking good mate! Interested in how the suspension changes will change the handling.
Is there any tea in that mug? Or do you have really milky tea? :naughty:
