  1. The mishimoto ones closed under full load on mine, I spotted it on the dyno, hence why I went for the HPS ones because they are thicker with reinforced silicone:) I'll bring them in and weigh them and pm you
  2. No i will do £40 plus post though or collect from H-Dev Did you buy mishimoto pipes ?
  3. 30 mins labour for an experienced mechanic
  4. Any left hand drive car on UK roads is a pain in the A** , might be fun in Europe though and for the summer might be an option
  5. Similar wheels to my Octavia VRS , also as much car as you really need for the road and a great daily, but just not special enough
  6. Your location might help if you are looking for recommendations
  7. There are an incredible amount of variables that influence how much power a car can put on the rollers yes, and most of the things you mention there would influence the amount of power to the wheels and therefore the calculated flywheel figure would vary also, even the way the car is strapped down can impact figures. To all intents and purposes a calculation of 18-20% is pretty accurate, but the bottom line is that if you want an accurate flywheel figure you need an engine dyno As I said before customers want the big number sheet, how many people post their whp dyno sheets ? Not many, nobody wants to say that their 370z with bolts on and a map makes 250hp but that fact is they do You would have to ask Jez what the Dyno Dynamics uses as a calculation I would guess its close to 20% These big rolling road meets should be treated as what they are , a bit of fun for like minded people who have an interest in cars to meet up and have a crack not as a means to get accurate data from your car , chances are the car wont be strapped correctly or be set up properly before the run is done , this all takes too much time if you did it all correctly you would get 4 cars done in the day and you would only provide the measured wheel or hub data
  8. That's what most chassis dyno's do for two reasons 1) The market is customer driven, there is no need for a flywheel figure at all but people want the biggest number 2) They have to use something and a percentage works well as an average across a variety of makes and models No idea , the only company I know with both an engine and chassis dyno is Norris Designs they might be able to tell you There is literally tons to read on this subject some good stuff written in the US but take their figures with a grain of salt as their dynos typically read much higher than ours http://www.hotrod.com/how-to/transmission-drivetrain/ccrp-0311-drivetrain-power-loss/
  9. Never have, wouldn't even know how to. They just rape me while I bend over taking it screaming "YES MORE PLEASE", because I'm far to lazy to do anything about it and would prefer to spend my time sitting on the bog shitposting on Reddit. Hmm, I should get an accountant. Never bought fags back for someone on holiday, always made sure you declared ALL your holiday purchases, never paid a price "for cash" or done a "cash in hand" job, never had an overseas purchase slip though the customs charge most people have at some point.
  10. Because drivetrains are not 100% efficient . For example if your gearbox is 95% efficient then its loses 5% of the power going through it , thats 5% of 100hp or 1000hp
  11. Its varies, is the short answer . The easy way is to use the measured wheels or hubs figure rather than the calculated flywheel power because different dynos do the calculations differently
  12. You said transmission losses stay the same irrespective of how much horsepower the engine makes, its not a true percentage but more a sliding scale but they are certainly not fixed
  13. No not really , transmission losses are a percentage , the resistance goes up with the horsepower you are moving the same mass yes but quicker and so take more effort
  14. I bought one of those £15 ones from Maplins today , on idle 1 m from the tailpipe my car was 110db Yep bit fruity
  15. Most people have done some kind of tax evasion or avoidance in their life and seem totally fine with it but when someone else does it suddenly its another matter altogether
  16. Uprev makes a nice difference on the auto's especially , no huge power increase but car will drive much much better and no CEL's
  17. Bit like Smelly Beaver air fresheners , neither grab me , cant see me buying them I think the market is totally flooded with products many of which all yield similar results if used correctly
  18. If only you had a specialist locally that could fit bushes and sort the alignment Hard to tell on the pic exactly what I am looking at but we stock most SuperPro bushes http://h-dev.co.uk/?...pension&paged=3
  19. Just looks like its not closed properly into the catch on the nearside
  20. You have a big wedge to put towards a gtr for sure The A45 doesnt really float my boat at all
  21. If its illegal then they shouldnt do it , if its immoral then the law should be changed to make it illegal imo
  22. TTRS or BMW M4 would be on my list , although you have to add a chunk of change for the latter
  23. and then chrome them or powercoat them a colour like blue to match the car
