A couple of weekends back I took the car to Blyton for the Brightgreendetailing mlr sprint.
Its taken me a while to get around to writing up what happened with it overall being a pretty annoying day I havent really been enfused to find the time to do so lol.
The format works that you are assigned a number (I was number 29) and you queue up in order and do a run around the circuit..
First practice run came a bit quicker than I expected after the briefing and jumped in to find the battery flat.. doh..
So I went out for a passenger ride in Damiens car and CJ's car and was sat there thinking I am not going to be able to abuse my car enough to be competitive, I have made a mistake bringing it.. then my run came and in the queue for the start line realised that I hadnt even launched the car yet as the uprated shafts only went in two days before and I didnt bother trying to brake the originals...
make it to the line..
light changed to green.. and I am away, launch feeling pretty good
wheel spin, next gear, more wheel spin, next gear and grip and it feels good.. brake and turn into first fast bend, feels good.. get to next slower bend (damn I havent turned powersteering on lol, flick it on, thats easier), rest of the lap felt good.. plenty more time to come but main exercise to check the car handles okay and the baffled sump works well enough for circuit work.. both all good, and I was wrong as I enjoyed abusing it
Next practice comes and I am more relaxed with the car and start pushing it a little more, still on the vpower 1.1bar map, this time CJ is in passenger seat. lots of fun trying to keep car in a straight line and not sideways under power out of bends..
Second practice is some 6seconds quicker than the first one and I still dont really know the circuit.. really starting to enjoy myself.
Third practice run and Damien comes out in passenger seat... I decided to up the boost a little and selected the 1.4bar setting.
Launch isnt too bad, get to first bend doing about 110mph and lift off the throttle and engine doesnt decellerate.. the throttles jammed fully open..
feck.. kill switch and on the brakes and into the area beside the bend (luck it was there).
Towed back to the pits with tail between my legs lol.
stripped throttle over lunch and can find nothing wrong.. not particularly clean but nothing obvious so a good clean and it is working freely with no issues..
after lunch go out for first timed run with Daz Davies in the passenger seat..
Unfortunatly the throttle issue was still there and it was again game over at the first bend
http://www.youtube.com/watch?v=6MpBmp0MWpg&fea...
I then spent a fair bit of time stripping it down and the second spring appeared to be doubling over so as a last ditch attempt the second spring was removed and the throttle cable slackenned right off.. the problem was I couldnt test it as sat there it worked perfectly with engine running or not but only jammed after the launch etc.. even sat in the car with throttle pinned for a few seconds and it wouldnt stick and worked freely..
Many thanks to anyone else that helped out too at this point whilst I was stressing.
Out again and same thing.. lots of head scratching and then Paul Martin to the rescue, he had had the same issue on his evo, the bearing is pressed in on one side and the boost pressure pushes the bearing out slightly and moves the butterflies with it and they jam.. hence we couldnt simulate the issue in the pits and ones moved the throttle was fine.
Temporay fix done but decide it wasnt worth the risk running the car again with only 2 runs left before the end of the day, if it jammed at the end of the back straight it would be game over. Thats motorsport I guess.
Happy the car handled well enough to be thrown about and the sump held off surge (at least for my practice sessions anyway, yet to be seen at higher G).
suspension updates planned as although the car handled okay there is a lot of body roll and Lift under power

With totb coming up thought it time to get some jobs on the car sorted.
Main thing being it needs to be able to dress in drag and still play on the handling circuit and track.
Trailered the car over to tfs racing today for us to work on it
New suspension
New brakes
New wheels and tyres
New handbrake
Clutch switch and flatshift setup
Oil and filter change
Will sort some better pics but you get the idea
Massive thanks to stew, craig and ian.
Also thanks to Alyn at as performance for posting out brakes bits at short notice

took the car drag racing at elvington and was fantastic fun..
fastest time was 10.01seconds with still more to come if I could get a perfect run together.
couple of videos

not actually proper slicks, just devoid of tread...

new exhaust system - hopefully help exhaust fumes go out the extraction when on the dyno, flow better etc.

I have a brandshatch gremlin to remove, I smashed a car up there years ago..
Blyton really helped give me confidence in how this car handles and I am itching to get it on track but due to wanting to see my kids grow up my weekend time is limited so the odd sprint, 30-130, drag run and totb are going to be this cars main haunt for a while..
Hoping to get a trip to the pod in this year.. but seaons coming close to an end.. oh and I forgot to mention I managed to strip first gear at elvington lol so car currently doesnt have a gearbox, although repair is in progress.

Busy week for the car and me, tfs, teg sport, ian (bod).
Realised there was a test and tune day at santapod coming up on 21st sept that worked with my mapping schedule perfectly so rather than the relaxed fix the box when I get around to it, it became a rush and last minute dot com.
Thanks to teg sport for building the box nice and quick.
I didnt want to risk it being delayed by a courier so dropped it up there and then on wednesday headed off to collect it (2x650mile round trips). Had a busy mapping day at tfs on the thursday so whilst I mapped the cars stew and ian fitted the box. Clutch was being a pain in the ass and box came out and back in several times late into the night to get it sorted and I cancelled the dyno time booked for my car at surrey rolling road to tweak for the new exhaust and I headed north with a working car strapped on the trailer at 10ish and started the task of searching for a hotel that had a room spare and space for car and trailer and that I could be happy leaving it.
Friday morning came way to quick and rolled up at pod at 8am.
First run on r888s straight off the trailer and all good but car felt slow, it didnt scare me.
Think is was a 10.7, which wasnt bad on the r888s but car was noticably less powerful.
Checked logs and rich and so made some adjustments but my mind wasnt happy as it shouldnt be rich.
Another run on r888s and it was better but still down on power.
Then notice in the logs the battery voltage is 11.7volts - doh.
Tried few checks and wiring all good, thanks to stew and ian for help. Conclusion was alternator dead, which was always a question mark over whether it would be okay and it had been fine until now. Logs from elvington show 13.9v.
To an extent I was pleased to find that and pleased I was correct it was less powerful.
As everything else on the car was 100% and I was there and had paid for the day thought whatsit to it and put drag wheels and tyres on and used jump pack to start it as battery got lower still and ran with electric powersteering off and enjoyed running it anyway, more quarter miles under my belt, all good fun.
Quickest was 10.14 if I recall correct.
So no 9s for 2012, that can wait until 2013.
would have been quicker had I not tried to hold 4th across the line and t
tted the limiter

I think this was the 10.14.. blast limiter again lol
Jolly green monster run at pod
last run of the day I think (you can see the weather coming in) I was sat watching the water temp climb going "come on ffs"..
whose got the biggers crack (on gearchange lol)

Waterways are ported and no thermostat and an evo6 rad, modified to add bleed pipe to headed tank which is 2litres.
Not had any issues with temps since, I am intending replacing ecu from a syvecs s6 to an s8 so I can add more sensors to monitor but sometimes you can monitor and worry about to much.
Not fully done the car justice yet. Run a 9.82 but plenty more to come.

will monitor
also looking to start building a stroker 3.6litre but not rushing into that so may look in more detail, was hoping to get the odd track day in this coming year and sprint.. have another cheap 205 track car that I can use instead so if it won't take about a 15minute session on track then it is likely to remain drag orientated this year. I had a headgasket issue on the previous engine but this current engine touch wood has never got warm.. the other one used to get hot after a run on the return road, but clearly was the gasket issue rather than a cooling system issue.

Simon, the headgasket on the left side of the engine would blow because of cooling restrictions. A fellow SVX'er in Australia was doing some R&D on the cooling system of the EG33 using a bench setup and clear pipings while revving the engine as high as 10,000rpms. A lot of cavitation appeared and he had to do tweaks as he goes. The R&D is still not over, but he hit a homerun on it till 8200rpms.
