cars look good.
saw the video on FB
shame about the cooler hose. get some Hydraulic hose's made up like Vocky said.

So put the oil hose back on today and filled her up with some oil and ran her up and no knocking so happy days. Will be making some better hoses up to prevent it happening again.
Removed all the gravel and gave it a wash
Few pics my friend took on the day, the coupe is just a timeless shape imo

With some front aero it'll look awesome! Making me want a big f**k off wing on mine
. How was the cooling side with the intercooler over the charge cooler? Vast improvement?

A front splitter is on the cards before the next race at Silverstone. I've noticed no side effect of the intercooler conversion, there is no lag between acceleration and gear changes. I want to fit a couple of temp sensors one on each side of the manifold to see what the temp drop is.

Few more pictures from the race
Carrying on the mods/repairs, fitted a new driver mirror to replace the smashed one, added a O ring to the rear view mirror ball and socket joint, has stiffened it a bit so will hopefully stop it tilting down (extra weight from the wide angle mirror), fitted a earth lead up into the bay from rear battery earth point to try and help the lazy starting, I think it's the battery just hasn't quite got the start up current engine needs due to the charger being on, it struggles at times.
Made some front and rear door cards to hide the holes and neaten the look up, used 3mm foamex and stuck on with double sided foam tape

Last few of race day (I promise) and a video (off my laptop screen as my WiFi is still down)
First time at Donington Park GP, just starting to get some heat into the old semi slicks on the cold damp track (dry only on racing line) and chasing down the Army drivers 480bhp AWD R32 Skyline GTR before the high pressure oil feed line to the oil cooler started leaking and eventually span me off into the gravel.

So after a very wet qualifying the Toyo T1R's just weren't up to the job and come as a E rated wet tyre so I wanted something much better
So treated the car to some A rated uniroyal Rainsport 3's, which are imo the best wet tyre on the list of tyres were allowed to race on, whipped them on and balanced them up
Few extras bits I've bought, magnetic sump plug, cheap pit stop timer, gauge holder, aero catches for the boot lid (boot has to be openable) and a air temp sensor gauge so I can keep an eye on my inlet temps
Dropped the oil and change the filter and got some 1/2" bsp hoses made up, had to make a fitting as they didn't sell one that has the thread that fits the block
Made a boss for the sensor and welded it on
And all fitted

^ that ones 3 times the price nearly
I got this one:
Look at this on eBay http://www.ebay.co.uk/itm/222451822756

Finished fitting the gauge for the intake temps
Bought myself a laptimer, went for the Pitking GPS LT1 which has a built in 10HZ GPS and has features like thumbs up and down for fast and slow laps and has a dash mounted beacon so no pit wall beacon needed. Made a bracket and fitted it in line of view

Been doing the last few jobs before the race on Saturday at Silverstone national circuit.
Got picked up at Donington scrutineering due to not being able to open my boot so fitted some aero catches
Made myself a cold air feed for the air filter, bit of 2" tapered alloy tube onto a plate
Riveted in place
Loaded the car up and set off at 2315 and arrived for mapping at Courtenay sport at 0420 few hours sleep and up again to unload
So the car decided it didn't want to talk via the obd port, I knew it previously worked as that's how I found the immobiliser fault, after several hours Matt had tried everything he could and even bench tested the ecu. I then suggested cutting the immobiliser wire feed I'd added as that's the only thing to have changed and it worked first time.
We'd lost a lot of time so only did a handful of runs just to check the map was safe and luckily it was, the smaller pulley had leaned the map out nicely to 11.9 on the lambda. Turns out my oem wideband sensor must be knackered as was reading 10.0 at WOT so I'll order a new one.
Matt and Jon were really impressed with the intercooler setup having never seen one before and we're certain it would improve the intake temps which was good positive feedback. We did notice that some of the silicones suck in on idle due to the charger screws creating a vacuum and sacking against a closed throttle body but once revved the positive pressure blew them out fully again. Doesn't effect how it runs but will make some solid pipes up with just a few short joiners in future.
So results were 267bhp and 226 lbs ft of torque at the crank which is exactly what I wanted as that now gives me 230whp and 198bhp per ton so I have a little to play with on the weight side but right up to the 200whp per ton Class B limit.

nice one
that cooler set up must help no end on track to keep a more constant inlet air temperature.

In qualifying I didn't see higher than 41 degrees and that was after 15 minutes hard driving

So race day at Silverstone national circuit and the Royal Navy and Royal Marines best turn out so far
The Armed forces pit village
Qualifying went alright, was stuck behind faster cars in a straight line but slow on brakes and cornering which was annoying.
Into the race and after a awful start due to lots of wheel spin I dropped 4 places but fought back to re gain them. Struggling to get heat into the rear tyres I cut too much of copse corner curb at about 100mph sending me a bit sideways, I was expecting a bit more and put too much lock on and got a tank slapper on, pinning the throttle didn't pull me straight and next minute I'm heading backwards into the tyre wall.
Cars a bit of a mess at the back but my bodyshop sponsor says it's sortable so it will go again
Didn't let it ruin our weekend and chilled out with some ps4, bbq and beers
Car looked good before the crash at least
You tube video of the race and crash
