  1. I guess I could be you've seen my profile picture it's Friday Guinness all the way day 😂
  2. The one I used was K&N and they have to be oiled 🤗 Big Rat
  3. Russ Does the filter come pre oiled, or do you have to spray it before use. I fitted a panel to my 911 when the exhaust was done messed with the MAF I guess I got the oiling wrong. They do 'assist' with the sound though 😏 Big Rat
  4. Looks - discreet but naughty Reliability Performance Should only have been available in silver 😂 Switchable exhaust That clock 😳 Toyota Evora 😏 GSF RCF Big Rat
  5. Don't forget my cut for the indirect recommendation 😂 Big Rat
  6. Personally Lexus Bristol have been great with my IS-F in the twelve months I've owned it. Spark plugs replaced at a fair bit less than others have mentioned on forum. Immediate action over warranty claim - water pump replaced the same day. Major service a few weeks ago with gold club discounts applied 👍 Big Rat
  7. Hi Stuart Yes you are right to walk, if it the Lexus servicing could have been validated that it was worthy of consideration, what are you looking for year/ colour wise I believe there are one or two on sale or shortly to be so from members on here, will keep an eye out for you. There was though I think it may have gone a low mileage white on at Lexus Exeter it was a car previously local to me. Big Rat
  8. The thing is as always there are so few of them, if you go into this eyes wide open carry out all the checks. If it has a Lexus history not that difficult to resolve, low miles if someone wants a keeper and the price now is more realistic Got to be worth a look, I do accept the insurance resale caution if you are only going to keep it for a year or two. Bought mine with a replacement service book similar mileage ok not had bump, and I'm extremely pleased. Big Rat
  9. Any one seen this before-not the whole article just the gearbox section. Big Rat The IS F 5.0-liter V8 engine is mated to the world’s first eight-Speed Sport Direct-Shift automatic transmission. This new transmission blends the performance characteristics of an automated manual-type transmission with the smoothness and refinement of a planetary-type automatic transmission. As a result, the driver can choose between ultra-quick manual shifts for performance driving, and smooth automatic shifts when convenience is the top priority. The driver can shift manually using either the console shift or steering-wheel-mounted paddle shifters. The eight-speed transmission is approximately the same length and width as the six-speed transmission used in other rear-wheel drive Lexus models. The transmission has a die-cast aluminum case and some aluminum internal parts, which contributes to weight reduction. Using eight speeds allows gear ratios that maximize torque up to the tire-grip limitations in the lower ranges while optimizing efficiency. Driving enthusiasts will appreciate the transmission’s Manual mode (M), which will hold each gear to the 6,800-RPM redline. A pair of unique paddles located within a fingertip’s reach behind the steering wheel enables the driver to make ultra-fast up-shift gear changes. Paddle-shifting operation is allowed in either D or M modes, but shifts are quicker and more direct in M mode. At higher engine speeds, downshifts are accompanied by automated and precise throttle blips to match engine rpm to vehicle speed. In addition, a Sport mode switch on the dashboard allows the driver to select from among Normal, Sport and Snow driving modes. In Sport mode, the VDIM system allows higher dynamic thresholds before intervening, alters steering assist to increase steering weight, and throttle response is sharpened. With the transmission in D mode, gears are held longer in response to throttle input. Versatile Drive Mode When the driver selects Drive mode (D) using the console shifter, the eight-speed transmission provides quick shifts that are smooth and befitting a Lexus. At the same time, D mode offers plenty of versatility with full torque-converter lockup in 6th through 8th gears to optimize fuel efficiency. A flex-lockup clutch operates in 4th and 5th gears, continuously controlling lockup-clutch slippage to enhance fuel efficiency. Until the engine reaches operating temperature, and when the VDIM system detects slippery road conditions, the transmission will automatically select 2nd gear start. Once the engine reaches operating temperature, or VDIM detects better road conditions, the transmission allows 1st gear start. From D mode, the driver can select M mode by moving the console shifter into the M slot, or can gain temporary sequential operation by keeping the console shifter in D and operating the steering wheel paddle shifters. The latter is useful for situations where engine braking is desired, such as driving through a hilly area. Paddle shifting while in D mode, however, is not the same as in M mode. If the vehicle is stopped, or if the vehicle is at a constant speed for a certain period of time, the transmission will change back to normal D operation. In addition, the driver can switch immediately into normal D operation by holding the upshift paddle (+) for one second. The transmission uses flex-lockup control and deceleration control when decelerating while in D mode, using as many gears as possible and extending the fuel cutout for maximum efficiency. AI-SHIFT (Artificial Intelligence-SHIFT) complements the driver’s Sport switch selection by automatically adapting the shifting based on road conditions and driver input. The new transmission is also highly responsive to uphill/downhill driving, always selecting the best gear for power or engine braking. Because the IS F is a Lexus, the intuitive powertrain control optimally smoothes out off-the-line response. Sporty Manual Mode Manual mode (M) goes beyond simply allowing manual gear selection by changing the transmission’s operational behavior to facilitate performance driving. In M mode, the driver will experience the feel of a manual transmission. Specifically, one will feel immediate g-force during acceleration and deceleration. In addition, the transmission uses downshift blipping control to match engine speed for high-rpm downshifts. The driver selects M mode using the console shifter, which then allows upshifts by pushing forward (+) and downshifts by pulling rearward (-). With the console shifter in M, the driver can also use the paddle shifters mounted behind the steering wheel. In 1st gear, the torque converter operates to provide torque multiplication for consistent launches from a standing start. The torque converter is locked continuously in 2nd through 8th gears to provide a direct connection between engine and transmission for the fastest shifts and most direct driving experience. In M mode, gears will be held until the driver up- or down-shifts. Two exceptions are if vehicle speed falls too low for the selected gear, then the transmission will downshift automatically; and if the transmission fluid or engine coolants exceed limits, then the transmission will revert to automatic operation to prevent damage. Shifts In 0.1 Second And Downshift Throttle Blipping New hydraulic-control technology allows the IS F 8-Speed Sport Direct Shift transmission to perform on par with manual transmissions without sacrificing the smoothness of a torque-converter automatic. In M mode, upshifts are executed in just one-tenth of a second, six times faster than manual shifts in the V6-powered IS models. The transmission-control system uses high-flow linear control valves for engaging and disengaging the clutches. The resulting simultaneous release and engagement of the shifting clutches provides fast shifts while diminishing gearshift shock. The solenoids allow direct control of the hydraulic pressure applied to the shifting clutches, along with centrifugal fluid pressure canceling mechanisms, enabling finer control than conventional clutch-control systems. In addition to a conventional input-shaft speed sensor, the intermediate members of the gear train use a speed sensor to allow finer control of gear changes. Driving enthusiasts pride themselves on the ability to execute a perfect manual-transmission downshift, which requires "blipping" the throttle while the clutch is disengaged to match the engine speed for the lower gear. The IS F transmission executes perfect downshifts in a similar way but with the consistency most drivers cannot match with a manual transmission. When a downshift instruction is received, the transmission control system quickly opens the electronic throttle, instantaneously increasing engine speed (blipping) to match the engine speed after the gear change. Simultaneously, the system completes the gear change by smoothly and quickly engaging the shift clutch. The downshift, with throttle blipping, occurs in just 0.2-second. To enhance performance and durability, a breather system separates air bubbles from the transmission fluid during performance driving. The transmission is also equipped with an air-to-liquid automatic transmission fluid (ATF) cooler to help ensure optimal transmission performance even during track driving. There is a transmission fluid temperature warning-light in the instrument panel.
  10. When I bought my E46 CSL M3 in 2004 people would say so it's got a plastic roof sounds a bit better but it's got a s... gearbox. Try and get a decent one now for less than 40K. And in recent years people have raved about them, ah well I'm happy 😊 Big Rat
  11. Yes it's always a tough one, I tried to reacquaint EVO Magazine, they amongst others ran one on their long term fleet in 2008. Emailed them 10 days or so before the last little Kemble meet to see if they would be interested, no reply not surprised it was a shot in the dark. My point is if we listed all the mags, and on line mags and made a concerted effort to make contact with inviting them to meets and so on it's a start,anyone on here in these industries who could contribute? Big Rat
  12. I as well believe in time the only way is up so I'm starting to collect bits now ! Pointed the trusty tranny M5 North for a couple of hours last night to buy these from a previous IS F owner who had a number of sets these being the last from a buddy of his who worked on the UK IS F launch in 2008 as part of the demo/press fleet. Also got the touch up pack hope all on here will find the number codes of use, used it just now a perfect match. Big Rat
  13. Pair of silver streaks heading north, gotta be drier by then than the two visits to Kemble ! Big Rat
  14. Ha no estate agent is going to get me in the red, I'm quite happy just being silver and nearly sixty 😂 Big Rat
  15. Never noticed that, I will go and play with mine tomorrow..... cough cough Still quite get my head round this as to why only 60 secs, I have noticed that if I'm in sport auto and start to descend a gradient let's say travelling at about 60mph the box drops down 2 or 3 gears. Quite normal, but if quickly push the lever on box to manual it goes up to 7th and holds by itself for some time, with no hunting. Anyone aware of or ever had any software upgrade for the box as a matter of course or as some sort of service campaign or recall. Big Rat
  16. Well there is a coincidence I'm around the Welsh borders that day, if I spot you I will be the mobile blocker a dark blue transit ! Big Rat
  17. Yeh I suppose I will happen EVORANTUALLY 😂 Sorry had to get the word in somehow ! Big Rat
  18. Ah 'Chatty Ratty 'spotted his name mentioned 🐀 In all seriousness chaps ''tis good to have the banter, some other forums I've been on it very quickly descends into some pretty nasty exchanges usually due to written misinterpretations, but as we all know as well the odd tw... Not met nor talked with a bad un on here yet - well except for Davi who could not quite hold his coffee on Sunday 😂☕️😂 Big Rat
  19. Long long experience, ah the joys of being self employed Now shall it be work - or coffee and biscuits - or start another thread on here 🤗 Big Rat
  20. Matey how did you know that, I made the mistake of leaving the large doors open whilst finishing off some gates, and another neighbour walks by and utters those immortal words. I don't suppose when you've finished you could replace all my internal doors 🤔 No probs I thought all on hear can listen for another week to my meaningless drivel 😂 Beats being on site in this weather !
