My big ZT thread > 15.4.08 25bhp/20lbft extra and track prep
heeman10 :
Pedal feel is still acceptable - the 20mm reduction in length equates to just under 12% more effort required at the pedal, which isn't more than I mind having to use. Tomorrow I will probably give the actuator rod one more turn then take it on the road to check out the gearshift and boost pressure. Outlook is good!
you sure are putting that engineering degree to good use
Out of curiosity, what Uni are/were you at? you were involved with FS too werent you? I only ask as i'm in my 3rd year at Warwick and on the FS project and on the look out for advice/jobs for the future
Well done with the work its a bute'

AndyRS1800 :Just to clear this up, i found that spot 1 nite with neil,
Its on the same road as the science museum, as [ERRR] facing the hilton hotel with the museum on [ERRR] left, turn right about 1/2 way up and you'll find it down there under the arches,
Its called Castle Field, I was there the other night getting a few shot's which you can see here..

We won't ask what you doing under those arches at night with neil
Nice photo spot though, cheers

Hi mate,
Just watched the newarmtest.avi
Just wondered though why you still seem to get so much compressor stall when the throttle is closed even though your running a recirculating dump valve? The standard re-circ valve on the SX isn't too bad but its got a bleed hole (which is easy modified not to leak though) but still only has a valve size of about 20odd mm so is easily maxed out but still dont give anywhere near the amount of compressor stall you still seem to get. Do you think the spring could be too hard?
I'm not bitching about anything, just generally interested so I can apply the best possible methods to my car
Cheers,
Kris

Don't worry about it, I ask a lot of technical questions about people's cars and its often taken as bitchy, semi-concealed negative criticism when all I want is a technical discussion
It could well be that the spring's too stiff, I should really have ordered a weaker one by now to see what different results I get (i.e. less compressor stall, or possibly a boost leak), but...I haven't! Lag is good on my setup anyway, since the turbo is a good match for my engine and power, and it has a fairly small exhaust housing, though you may remember that when I removed the dump valve, lag was pretty bad in comparison. So a more finely-tuned dump valve/spring may improve things even more, but even on un-hurried gearshifts the needle shoots straight back to full boost, and that's all that matters really
I'd love a speed sensor on the compressor wheel so I could plot turbo shaft speed graphs without a dump valve, with my current dump valve setup, current setup with a weaker spring, and then the current spring/weaker spring setups without the recirculation hose. Coming onto full boost then dipping the clutch with all five scenarios and running speed plots would tell all sorts of stories!

Hi James, glad you like it! I was at the University of Central Lancashire (UCLAN). I was involved with FS, and it is important when it comes to careers, though I don't refer to it much as I'm only really interested in a career with engine management and mapping. What area of motor sport are you wanting to move into? Best bet is to start talking to people NOW, I can't stress that heavily enough. It's too easy to believe you're caught up in university work all day every day, but we both know there are always hours and hours you could use usefully instead of "studenting" through them Just take yourself ahead 5/6 months ahead from now. You've graduated but have no job, and that situation doesn't end until you get a job, which can takes months of applying and failing, interviewing and just missing out on jobs etc, so the earlier you start, the better.

Well my current project could lead me down the Engine managment side of things, which i am very interested in, and belive it to be a fairly good part of the Automotive industry, which should see investment over the next few years with all the EU emmissions crap, but i've got that in my mind as a fall back plan. I'd love to see motorsports through and through, got a terribly curious mind, but mainly engine development however I'd like some experience in the rest of the car. Lotus' graduate scheme looks interesting however I'm not sure if its the best route into MS or if its more suited to the Automotive side of the industry. My real problem is getting advice. No motorsport firms offer much information about graduate intake or the best routes into it all, hence I though you might be worth asking Another problem I have is no CV, since 30 weeks away from home and my girlfriend is enough, never mind another 10 at work placements. I'm getting all the hands on stuff and learning I can when I'm at home but its going to be hard to convey that to an aplication form reader :S
I'm trying to get in with people the now but its not easy. The third year projects arent put at the forefront of anyones mind as all the concentration is on the current FS Team for 07. Though I keep pestering a lecturer to let me know when the ProDrive guys will be in again. Currently my project is at a standstill as I'm not wanting to do the proposal without a proper race ECU for fear of lack of control and problems with detonation, also the dyno needs a new exhaust extractor so i've been waiting on that since week 1 (now in week 13). We're trying to negate the effects of that silly 20mm restrictor by supercharging. I cant get anyone to give a yes or no to a better ECU though I belive its been investigated. Also they are now proposing that we sawp to a single cylider engine, which needs to be decided on by the current powertrain guys. Its a pain in the arse to say the least.
I'd like a little time off at the end of the degree, been in education since 5, and as i'm Scottish I'll be a year younger than nearly all, if not two, since a MEng is 5 years back home. So applying for jobs could rope me into something which wouldnt give me the break, though I've not asked the indstry about this yet.
If you strike it lucky please let me know, I need any help I can get
I was going to ask the question about your compressor stall too, but someone beat me to it
All the best with the project, I absolutly love it, you've done a darn fine job.
Cheers
JAmes.

Cool I'm in the same position where my turbo will boost striaght back to a bar after gear changes without any pressure relief valve installed but I cant help feeling it could be a little more responsive wih a proper recirc and that little extra bit friendly to the turbo bearings and componants
Oh, thanks for the Roose Motorsport contact, nice fella I spoke to and they're making me up a hose with the same as you used (the nomex crap) on monday so could be back on the road by next weekend, woohoo!

Update
I washed it
It hasn't been properly clean since the beginning of November. So it got a wash today, will be polished/waxed/hoovered/interior cleaned tomorrow, then something at the back of the car will be changing on Tuesday - pics to follow! It's something I haven't been entirely happy with from the start for various reasons, so thankfully it'll be done in time for FITP and will suit the car much better than the current item
Boot included to show the lack of height at the front:
Mk3s on 15s can be deceptively low compared to those on 15s and 16s. I have around 3-4" ground clearance at the crossmember, which really isn't a great deal!
Random shot of the back end, including the article which will soon be gone
Random interior shot:
And alongside the Mk6, the underside of which I am currently treating in my new thread dedicated to the car >here<
And yes, the Mk6 will be washed, polished and waxed when I've finished the underside It was spanking clean before I did the 500 mile weekend that was the FT.com big night out last weekend!

Cheers ladies Not much of an update, I just felt like taking pics because it was shiny again..shame my phone was all misted up! I feel a nice day out on some scenic roads coming up after a polish, and some proper pics/videos. The weather's really looking up! Cold, sunny and clean, just the way we like it

Looking Good Mr. Forsyth! I'm gonna guess at rear wiper or number plate light as per twins on passionford along with smoothing your rear bumper to match the front...

gayrs :missed a bit
no you did, where the fuel lines are
What on earth are you talking about you weirdo?! Fuel lines?!
Jay - No outwardly-rolled rubbish
Scrub - Cheers I parked it outside before, meaning to polish it, but was faffing around with the Mk6, so tonight is its first night outside since Bruntingthorpe, and there's ice all over the roof! Turned the ignition on this afternoon, ACT gauge kindly informed me it was trembling at -2.6 Celsius lol

why dont you fit megasquirt to the car to practice the mapping etc that you want to persue????
just a thought

P.s. cheers for the help with the TD query

Scott - TBH I don't really like the idea of MegaSquirt, I'd rather have something a little more "mainstream", as snobbish and uninventive as that sounds. This engine needs no better management, as it's currently limited by the pistons, rods and turbo. If/when I go to the "next step", it will be a very different car, so it's safe to say it wouldn't have Ford or MegaSquirt management. We'll see how things go over the next year, but if it goes the way I'd like, I'll probably be chasing to duck under the 4 second barrier as opposed to 6

Update
I went down to a Powerflow dealer in Morecambe, Lancashire, yesterday afternoon as I've never reeeally been happy with my 3.5" inwardly rolled Mongoose tailpipe. It's always sat too low, not quite central, and looks so small! I made fun of Mikee_RS for ordering a 4" outwardly rolled bacbox, but it needs to be that size to fill the RS rear bumper moulding properly!
So, removing the backbox:
Chopping the tailpipe off:
4" outwardly rolled tailpipe turned round so the outer lip now sits against the backbox, leaving a straight cut tip:
Job done!
Before:
After:
I'm very happy with it. It's purely cosmetic, but I wanted a more "motorsport" look, for it to fit the bumper moulding better, and fit it to be lifted and centralised. Thank you Westgate Tyres
Also, I left it outside on Sunday night (-7 degrees), got rather chilled!
