You missed poor in crash tests , but they are cheap (worth repeating )

nope ,

Sorry mate thats nonsense, you wouldnt notice it. Drag slicks do grow (Top fuel dragsters by about 1m) but not steel banded road tyres and no street car is going to have any appreciable difference with rolling resistance due to dropping a few psi .

First off dont worry about offending anyone My advice would be to have a sensible discussion with their estate agent, mention you have looked at other properties and like this but want to understand why the vendor feels that the value is where they have set it

You dont lose terminal speed by dropping tyre pressures , you do however make it hellishly unstable when braking in the shutdown

Drag racing is much harder than many people think

I tried garage floor paint from Screwfix, then 2 pack resin based paint and also tiles and the latter have worked best for me , they arent perfect as heavier cars can cause them to move about a bit and in hot sun they expand but i've fixed mine down in a few places with gripfill and they seem fine, they are nice to work on They have been down more around 12 years off and on as I took them up for a bit due to them moving with the 370z but they still look pretty good They are the same as Jez has at H-Dev and they are still alright there , i bought mine off him as he had spares left over.

For those that are interested I am helping to arrange a RWYB at Shakespeare county raceway weekend 25-26th March with the Skyline Owners , more the merrier for a fun day out , no pressure no racing just trying to get the best out of our cars

There is a guy in the US that has run into the 12.6's with a 370z with just a few bolt on bits and a map , getting a decent time is all down the first 60ft

I follow this break in proceedure , have done for the last 20 years http://www.mototuneusa.com/break_in_secrets.htm All the cars I have run in this way have made more than the factory quoted figures on the dyno

This was a 12.4@117 in Reggie the supercharged 370z

Only in the world of top gear does horsepower magically leak from an engine over time.

Ive had more powerful cars than my Evo 6 but point to point its still the fastest car I've owned by some margin , awesome things

What bike was that? Homebuilt 1981 Z1000j 1428cc 14/1 cr and nitrous, around 300hp . Raced in the Competition bike class I built about 5 different drag bikes between 1991-2005 started with turbocharged ones and then went to high compression + nos

8.68@168 on my bike My n/a 370z ran a 13.2@105 The Supercharged 370z ran a 12.6@118 but only managed to do two runs , might have got a 12.2 out of it

Go on the dyno sheet thread but some engines are better than others and its not due to mileage

I wouldn't be surprised to see that kind of figure on a US dyno , I'm convinced the horses are smaller over there because they seem to get a lot more in the same engine Well that and their dynos typically over read by around 15% 430hp for the DE and 450 for the HR is realistic for supercharged engines not sure going any higher than that is

Wow , 10 years ago I was driving a Skyline and since then I have owned a further 10 cars !

Ah, fixed orifice, gotcha. So what happens in that system if you don't have a regulator? Pressure is determined by the fuel pump alone, I assume? Well, along with the natural restriction present in the pipework itself. Ah, fixed orifice, gotcha. So what happens in that system if you don't have a regulator? Pressure is determined by the fuel pump alone, I assume? Well, along with the natural restriction present in the pipework itself. You need a regulator to rise fuel pressure with boost on FI engines. You dont need an adjustable one but that's an easy way to get a gauge so you can check pressure and upping the fuel pressure can help you flow more fuel through a smaller injector meaning you dont need to fit bigger ones As you say in many cases the fuel pressure is set by a fixed orofice in the pipework itself Sorry but fuel pressure needs to be set to suit the injectors used, some require different base fuel pressure, so adjustable is needed, Also using higher fuel pressure to increase the flow rate of an injector is bad practice in my book, its OK for maybe a stop gap for a small power increase, but you will loose the headroom of the injector, Injectors should not use more than 85% of there duty cycle, so should be sized to take required power output at 85% of there duty cycle, which leaves some headroom should the ECU need to increase fueling suddenly if det or denser airflow is detected. It also helps prevent failure of the injector coil. I agree that upping base pressure isnt recommended however its a very common route albeit less common nowadays, I've never needed to fit an adjustable reg on any of my modified turbo cars

Indeed crap dealers dont deserve your business , I bought my 370z from Kettering, 80 miles away from me the salesman wasn't even phased when the rear stepped out a little on the test drive, I also test drove a GTR at Westover in Bournemouth and they were also excellent , would certainly buy from them. Not heard anything good about Nissan Aldershot personally but never tried them myself

Its regulating the pressure in the fuel rail , the return goes back to the fuel tank

I guess thats ok if you buy new but who knows what was standard and what was an option on a used car ? I'd never use Admiral to be honest , better companies about for not a lot more http://www.pistonheads.com/gassing/topic.asp?h=0&f=23&t=1646309&i=200

Guy on pistonheads is having issues with his claim due to not mentioning factory options, no intention at all to decieve , it is Admiral mind you but giving the insurance company any kind of "out" nowadays its not the smartest idea
