Twin turbo impreza type r
Discussion
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

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

I need a mad car like this in my life.
buy one then http://www.lancerregister.com/showthread.php?t=421...
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.

Fair enough, I did a fair amount of track time in my old Civic Type R and watching a bad accident put me off a bit.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..

I'm working on restoring an RB5 (number 125) at the moment so love to see your immaculate green machine in action!
