Update
Realised that I've not done a proper update on results and spec of the engine since RS Tuning rebuilt it.
It's now running 340bhp and 360lbft with injectors at 89% and turbo not pushed to the max. There's another LY Megane with same spec engine but upgraded fuel system running 375bhp so it's nice to know there is potential for more power in future if needed.
Here are the graphs after Paul finished mapping it.
BHP and torque at the flywheel
Boost and BHP at the wheels
AFR and BHP at the wheels
I noticed the Odyssey race battery was losing charge if I didn't use the R26 for a few days so I replaced it with a Varley 25. Reason I went with Varley this time is because it has better cranking amps and most importantly it looks better.
Next job was to replace some plastics, this lot and a new dipstick cost over £100!
My car never had these which connect the bumper under tray to the arch liners.
New arch liner as the old one had been eaten by the tyre.
Hopefully it won't happen again now it's got all the correct plastics holding it in place
Then once I had finished that I set about fitting my Ktec stud conversion kit which I bought a couple of years ago.
It didn't come with instructions so I copied the ones on the Pure Motorsport website. Applied loctite to the studs then torqued 20nm, refitted the wheel, nuts hand tightened, then torqued to 110nm after three hours. Good excuse to get spacers now :smile:
Rears definitely need spacers now.
Had trouble doing the rears as the wheels were stuck on. Got them off eventually by loosening the bolts and driving it up the road.
Noticed the pad was low so ordered some replacements, I thought it would last until next weekend but I was wrong 😂
The pad lasted until Tuesday which made for an interesting drive home so good job these arrived from
@George@RTR_Parts the next day. Decided to upgrade from oem Brembo pads to DS2500 because I've never been a fan on the oem pads and the fronts were being upgraded to Carbotech.
Carbotech XP8 pads arrived in time to fit them at the weekend along with the rear pads. Reason I went for the XP8 pad instead of the DS2500 again is the car is so much faster now that the braking felt delayed and lacked initial bite.
Started off by doing the rears. I got my money's worth out of these pads lol
Disc is clearly worn but I chucked the new pads on anyway.
Caliper back on (after a trip to GSF for a caliper wind back tool)
Luckily I just about got away with it on the passenger side.
Spot the difference between the old passenger side pads and new ones 😂
Front pads are usually much easier but the pins were a b*****d to remove. They're not the same pins I fitted last time I replaced the pads so that might have something to do with it
Carbotechs XP8's fitted
This shows how hard one was to remove, ended up butchering it with the hammer and punch:hammer:
Running in was conducted later that night as bedding process isn't suitable for normal hours. Bedding in requires four hard brakes from 70mph to 10mph with 30 seconds between to cool down, then four very hard brakes from 70mph+ to 10mph with 1 minute between to cool down. Then the fun part is 15 minutes driving using regular medium to hard braking with last mile using minimal braking to cool down.
The pads have been fitted for a few weeks now and I'm impressed so far. Braking from cold is good, no annoying noises, and the pads bite well as soon as you apply the brakes. They're definitely have much more power for same pedal travel compared to the DS2500.
Early today I gave it a bit on a clean as it was quite dirty.
Then I decided to remove the heat shield under the bonnet as it hasn't coped very well with the heat from the turbo.
Looks much better now, think I might have to find something to replace it with though.
Finally, I won a set of Toyo R888R after entering a prize draw on the Toyo stand at the Castle Combe Performance Action Day last month
