Thanks for all that.  I\'ve read some of Howards threads before and found his stuff is always very useful.

I have access to CMMs at out chassis lab, but it either involves me taking the whole car there and doing it on the flat bed, or taking it apart and doing it piece by piece - not such a bad idea as in four weeks I\'m off til September!

Thanks for that.

I\'ve previously bought some stuff from Jon but thought I\'d avoid asking any companies that make their living from those matters. I can understand that they wouldn\'t want to share their hard work, especially if that work gives them an edge

I don\'t need any information on aero, suspension  or brake setup.  The models main job is to look at how the contact patch changes in relation to the other parameters.  At this stage the springs and dampers wont be looked at.  However, it will be added later, and is something I can easily measure.

The limitations of the movement of the system will be dictated (mainly) by the contact points of the system.  There will be an amount of compliance in the system from bushes etc but again this isn\'t something I\'ll be adding to the first model.

The basic model needs to be right, to a good degree of accuracy, before I can begin looking at weight transfer and other more complicated details.  In an ideal world, I\'d be able to match the predicted data against some real data from a data acquisition system, but at the moment I need to be realistic.  I\'ve already asked if I can borrow a £20k PI system but my request was declined (no surprise :p)

With regards to weight, I will be looking at sprung and unsprung mass to carry out a few calculations but I seem to remember finding a thread somewhere with a breakdown of the weight of all stock parts.  That\'ll save a bit of work!

Thanks again
Chris

Hello to all!  Its been quite a long time since I’ve posted here but as I have a few FD related questions I thought it would be a good time to drop back in.

I’m going to be completing an investigation into the dynamic suspension characteristics of my FD which I will be starting in a few weeks.  I’ll also be looking at loads transmitted from the engine to contact patch through acceleration, and loads from the road back through the vehicle under braking.  

My main goal is to make a fully functioning kinematic model which can then be used to analyse how camber and toe change through ride height and roll, and to try and find optimum suspension settings.  The results of this will be down to the accuracy of my measurements and the information I can obtain.

I’m currently studying motorsport engineering & design, and whilst this isn’t an assignment or thesis it is of major interest and something I’d like to work on through my summer and continued spare time.

At the moment I’m trying to get a hold of as much technical data as I can for a bit of a background research and I’m just seeing what information is currently available.  I’ve found a few sites with generic sort of stuff but no real detailed technical data.

The things I’m looking for are at the moment are:

Powertrain & suspension pickup points with XYZ co-ordinates
Component dimensions or CAD models â€" doesn’t have to be to a high level of accuracy as I’ll be looking at individual items in more detail later
Any detailed technical data that may be of use
Any research data or papers that have details on the FD

Ideally I’d like to get my car to Uni to make use of equipment on site. More likely I will need to invest in a flatbed over summer and borrow some measuring equipment and record all the points I need at home.  I’m expecting this to be a bit of an ongoing project that will hopefully prove useful in the end

If anyone knows of any resources or if anyone has their own data that they are willing to share please let me know.

Thanks in advance
Chris

Your ported then Twisted?
 
Im in the same boat now, .79 bar on twins i want .9 so FPR, pump and secondaries. where is this kg parts kit listed? and is it easy to fit?

Yes I am!  

The only thing that holds back the boost on the car is the wastegate - Pip said it needed to be ported and it could run 1 bar happily which would be nice.

The fuelling upgrades he made would be more than sufficient for that.

Chris

Yup, I was thinking of 850\'s all round, but I always promised this car would not be skimped on, so i wanted to keep the primaries and get bucket spec secondaries so i could keep the low end driveability as good as poss

Any suggestions for rails etc?
Injectors? I\'m sure it\'s got to be possible to get it cheape rthan a US sourced KG parts kit
(runs off to his favourite RHDJapan )

Shame all the exchange rates suck right now...

When I had my engine rebuilt by Pip, he suggested getting 1600cc secondary injectors.  The car already had a walbro fuel pump on it.  It was a few hundred ££ though - speak to him and see what he recommends.

Just to let you know, the car is 333 rwhp (395fwhp) on the twins.  Driveablility is great, car is mapped conservativley and the duty never goes above 80%.

Hope this helps.

Regards
Chris

395 fwhp on ported engine - all done by Pip.

Ok, having some issues with my lights.  I\'m in the middle of having the popup lights re-fitted with a HID kit, as opposed to the sleek lights that were previously on it.

Recently, the sleek lights decided to stop working.. which I suspected was down to their poor build quality and bad wiring.  The main beams would only work when I pulled back on the stalk, but not when the stalk was pushed forward for full beam.  One click on the stalk brought the side/tail lights on.

Now they have been removed, my friend who is a mechanic but not an autolec was testing the electrics before we fitted the popups and HIDs.  The problem is he couldn’t get the popups or bulbs to light up at all.  Side lights and tail lights are still fine.

Fuses have been checked, relays have been checked, and lives & earths have been checked and seem to show good figures.. but still no luck.  I also have a spare stalk set which we tried but didn’t seem to make a difference.  Does this mean I have a loom problem with the switches?

Is there anything else that should be checked.. any sneaky hidden relays or fuses.. or am I looking at getting a proper autolec out?

I\'ve searched as many topics as possible but cant seem to find anything to make them work.

Any suggestions or ideas would be much appreciated.

Thanks in advance :cheers

Chris

Depending on the bulb size - you could always get the HID kit from Clive.

but i do like this one

 
as its got a 95mm dish so mayby can get my leg between the wheel and the dash for a change,

That\'s the one I\'ve got.  It\'s got a lovely feel and its very grippy

A mix of V power and Autosmart berry blast!  Mmmmmm

Just remember, mapping a rotary is a lot different to mapping a car with pistons.  

I\'ve got a quite a few friends who have been to Westec and they seem to get a varied response.  Stick to one of the well reputed rotary tuners and you won\'t go far wrong.

I live in Swansea and travel to WGT in Cheshire.  It\'s a 420 mile round trip and worth every penny!

Chris

I meant delete my post not yours :p  

Sorry for the confusion

misspost.... mods delete

They\'re bored out 850\'s. I have the 1200\'s, but they\'re safe as they\'re not bored out as much.

That sounds about right.  I was told that there was a problem with the 1300\'s maxing out and stopping.  As a result I went with 1600\'s to be on the safe side.

Mine went with a spectacular flame and a big cloud of smoke because one of the secondary injectors failed under high duty.  

Moral of the story - don\'t go for 1300 secondary injectors (bored out 1000\'s I think?).
