MrLizard Posted October 27, 2010 Share Posted October 27, 2010 TLM 350z Since the Nippon Challenge Race at Lydden Hill TLM and Abbey Motorsport have gone back to the drawing board. Due to treaded tyres being in short supply and prices rising the only logical step was to advance the car... that makes sense right? The decision was made to move onto Dunlop Racing Slicks. With any car, changing from road tyres to slicks will give a significant performance boost, however it does come at a cost. In order to effectively use the slick tyres we also needed: New larger Oil Sump Modified Oil Filter New Wheels New Wheel Bearings New Suspension Dual Fuel Pumps Camber Arms And finally get the Dash Working! This is basically to cope with the increased forces applied to the car when on slicks and make the most out of the available grip with the added benifit to see where i **** up whilst going around. Abbey Motorsport completed all the necessary modifications and we went to Brandshatch for the first shake down. The first thing we noticed was the greater need for heat in the tyres but once the heat was in the tyres (55-65 Deg of it) the grip was phenominal. Due to an unfortunate problem with part of the suspension we had to call it an early day but the testing gave us some good figures and resulted in a positive step forward. Huge Thanks to Abbey Motorsport for going the extra mile and our other sponsors: Total Nissan Zenzero IT Support Opie Oils UpRev Motordyne **REMOVED** Some cold carbon And so much grip now it can handle 90deg increase in gradient and without moving still be ok!

Darren-B Posted October 27, 2010 Share Posted October 27, 2010 Nice work Steve, (and Abbey M/S) I will take a look around your car on Saturday when I visit Abbey with Wasso if thats ok? Promise I won`t touch anything Quote Link to comment Share on other sites More sharing options...
MrLizard Posted October 27, 2010 Author Share Posted October 27, 2010 haha thats fine m8 New LSD in the process of going in but im not sure it will have arrived by saturday, looking to do another test day at brands imminently, just waiting for Abbey to decide when suits them. Also a new rear subframe floating around but we are not going to fit that until we get past the next test session. Quote Link to comment Share on other sites More sharing options...
introspect Posted October 27, 2010 Share Posted October 27, 2010 Looking very Out of interest what suspension are you using now? Quote Link to comment Share on other sites More sharing options...
MrLizard Posted October 27, 2010 Author Share Posted October 27, 2010 3way adjustable AST, really nice peice of kit that Abbey with AST have altered to suit the 350z, I believe we are on our 2nd or 3rd set of springs and the ride height overall has been lowered so there is more adjustability lower down... felt nice (though a little soft) around brands last time, we are going for a stiffer setup next time to see how it performs, car felt like it was skipping into grip, like it would load up one side or the other and then skip slightly and then dig in, you really have to leave your brain out of your head when the slicks get up to temp, surtees flat out was interesting Quote Link to comment Share on other sites More sharing options...
introspect Posted October 27, 2010 Share Posted October 27, 2010 I've never driven on slicks but I'm not sure my brain would let me trust that much grip is available I think I'd have a trouser accident way before the slicks let go! Are you using a square setup with the wheels? Quote Link to comment Share on other sites More sharing options...
MrLizard Posted October 27, 2010 Author Share Posted October 27, 2010 not sure what you mean by square? 9.5" fronts and 10.5" rears with lots of negative camber everywhere as the last picture sort of shows... The setup is something im not willing to reproduce on a forum as it isnt mine to divuldge in full anymore (lots of alterations this year) but given my experience with Abbey I know they will be able to give you a good setup taking into consideration what you actually want to do with the car, ie normal fast road road/track track etc...

introspect Posted October 27, 2010 Share Posted October 27, 2010 Sorry, from looking at the pics I thought you had the same width wheels all round rather than a staggered setup as normal. Wasn't really looking for a full spec on your setup, just interested that's all I know your car is purely functional rather than being made to look nice, but it looks cool. Even the big wing (which I'm not usually into!) Hope the rest of the testing goes well. Quote Link to comment Share on other sites More sharing options...
MrLizard Posted October 27, 2010 Author Share Posted October 27, 2010 thanks introspect, im not really interested in the show aspect, but do appreciate it on others cars, the car has 100% been built for function but as its turned out i quite like the way it looks... Be nice when i get the other front bumper on and sort out a splitter in saying that if the sponsorship takes off next year it could end up any colour!

andlid Posted October 27, 2010 Share Posted October 27, 2010 looking nice, where's the vids?! a few Qs: New larger Oil Sump > Is this due to the more G's in the corners so the oil keeps going to one side or what? Modified Oil Filter > same here? New Wheels > Understand New Wheel Bearings > Is this due to the forces on the OEM bearings? New Suspension > Understand Dual Fuel Pumps > Don't understand Camber Arms > Understand ... I was going to throw my slicks onto my rays that I got and use them for a trackday, in the hope they'd be ok! (car) Quote Link to comment Share on other sites More sharing options...

I was going to throw my slicks onto my rays that I got and use them for a trackday, in the hope they'd be ok! (car) Vids soon m8, sorry!!! Larger sump due to oil surging to one side of the engine yep you got that Oil filter has moved closer to the oil cooler for ease of change and due to the new sump taking space! Wheel bearings, yes you got that too Fuel pumps, in my experience the OEM car has almost enough cornering force to starve the engine of fuel, with slicks its easy when running a low load of fuel, the zed runs a saddle tank and one fuel pump on the right hand side of the tank, if you are cornering hard right, doesnt need to be tight but quick then you can end up with no fuel coming in, the answer is to install a fuel pump on the left hand side and Abbey are setting this up so it pumps to the pump on the right hand side, so no need to run a whole new line saddle tanks great for weight distribution fortunately i have only suffered this in testing, we tend to overfill slightly for races but with 2 pumps and an accurate fuel consumption calculation (assuming im always at full pelt not safety car) then we can save more weight!

andlid Posted October 27, 2010 Share Posted October 27, 2010 lots of weight can be saved with accurate petrol levels In the biking scene its very common for trackdays seeing the lads pumping out fuel measure and then back in again note it and off you go... Q on the petrol issue and starvation: What happens say if you've driven around a track for a while and you take a lets say 45 degree corner following a straight and the car starves... could it be that it bogs down and "dies" for a minute, engine light on and then just recover and continue driving? btw, what sump are you getting? (guess it's not a normal spacer) What LSD are you intending on installing, hoping it's a UK one fuel pumps sounds interesting... so I take it your car doesn't have a fuel return system with constant pressure in it ? I also guess we're not going to see any install pics Quote Link to comment Share on other sites More sharing options...
MrLizard Posted October 27, 2010 Author Share Posted October 27, 2010 Good guess on the install pics some of it would require going back in time. Sump is American, abbey have the details, not just a spacer, LSD is quaiffe, uk You could have exactly the issue you describe, I have experienced it on a corner even less severe than 45deg, car took about 15 seconds to remove the error and carry on Unsure on the technical details of the fuel pump, I tend to eat biscuits and lose interest if it gets too mechanical, I like the geeky computer stuff more Quote Link to comment Share on other sites More sharing options...
Darren-B Posted October 27, 2010 Share Posted October 27, 2010 looking to do another test day at brands imminently, just waiting for Abbey to decide when suits them. Well let me know when this is, if I`m out of my cast I`ll come along in the SBR, need to do a little shake down run Otherwise I`ll just come along just to watch Quote Link to comment Share on other sites More sharing options...

Would be interested to see the oil filter relocation and sump details. So you're more interested in the lights on the dash you want installed then the backend workings ?

MrLizard Posted October 28, 2010 Author Share Posted October 28, 2010 more interested in the data we can gather from all the sensors and gps time sectors etc when out of the car more interested about the backend when in the car Quote Link to comment Share on other sites More sharing options...
djtimo Posted October 28, 2010 Share Posted October 28, 2010 Andy Steve's car may have done away with the syphone system the stock car uses with the sadle tank. One fuel pump+ hanger in each side of the tank with a Y fitting supplying the fuel rail would give constant pressure under high G force while cornering. I would have though a fuel swirl system would have been put in? (it may have??) but that adds weight and for race regs fuel components need to be be hind a fire wall and not in the driver compartment, this is hard in the zed as we dont have a sealed boot space like alot of cars do. Steve when you next at abbey can we get some inside pic's ?? I have asked RJN for info on the roll cage and a set of CF door cards to fit round the roll cage for my car! lol... Oh and come on lets see your splitter!!! Quote Link to comment Share on other sites More sharing options...
MrLizard Posted October 28, 2010 Author Share Posted October 28, 2010 the cf door cards are hurendously expensive but do look lovely, bob fitted them to a m8's 350z not long ago you wont be dissapointed... ideally you want a weld in cage as apposed to a part bolt part weld like mine, but for a proper job you are talking thousands m8 and there would be no going back from that, i should have done that really but at the time cages were thin on the ground so anything FIA approved would do... re fuel regs tim you can run the tank inside the car and you can run the lines through the car as well, you have to use a special material though and that has to be within another hose of a suitable material which in effect acts as a firewall... Most of the time you would run the saddle tank due to its better weight balance and run an additional tank to feed that rather than the other way round...
