Stan] Preparation of the engine before increasing the fueling. 1. It is necessary to unscrew the screws #1 and #2 and to withdraw the limit-switch. (you probably have a cover over), You can use tie-rap and fix the switch elsewhere (but it must remain open) TDI. 03 Golf Match ATD. Nov 15, 2008. #1. Hi All, I'm new to this forum. I'm a member of a UK Golf forum, but as an owner of a PD100 I find that any tuning questions I ask over there either get ignored or answered with "Buy a 130" type answers, I don't want to buy a 130 as I'm really happy with my current car and want to modify it lol. Agreed on saving for a faster car. I have an 06 1.6 Polo. Besides cosmetics - and removing the air filter restricter, that engine will stay as it is. Ask Echo03 on this forum just how much software and a freflow makes a difference. With regards to the decat - I may remove mine, too. It's like R150 or so at some places. Richard Hammond takes to the road in a Volkswagen Polo, assessing its performance, practicality and style. The 1.9 TDi Sport version has a turbo diesel engin 1.6 TDi tuning; 1.9 TDi tuning; 2.0 TDI 140-170 tuning; 2.0 TDI tuning (EA188) 2.5 TDI tuning; 2.7 & 3.0 TDI tuning; Getting a professionally flowed head with larger valves can fully release the engines power. Your clutch can sap a lot of your power if it starts to slip and the standard clutches are only ever good for power gains of up to 40 or There are lots of reasons to tune a PD105 rather than trade in for a faster car: Better economy and reliability than a PD or CR 140/170. Not taking the risk of buying another car with an unknown history. Cost (cost to change versus remap cost) Power delivery of the 1.9 engine (some people love it!) Oil knows better then I but at least on the old (1.6 na cars) the light on the dash is independent of the actual glow plugs working. I have a lighted washer sprayer hooked to the glow plug system in the rabbits to show when it is on and it never matches the dash light even with new glow plug relays (upgraded from slow to fast glow plug systems). From my experience, the idler pulley, and steering pump pulley should be completely smooth, while the idler pulley can make a little noise but should spin freely. The alternator has a clutched pulley that should spin the alt forward and free-wheel backwards. Try spinning it forward then backwards all of a sudden. They didnt make enough meat on the block where the head bolts go. Eventually turbo or not it will crack the block. I replaced my 1.6 early to a 1.9 german engine. What a difference. without the adenoid it is faster than the other engine. Also the same mileage. Pulls hills faster. More drivable. No turbo lag with the TDI turbo. Total amount of air inside assuming filled to half way mark = 0.9 liters. A drop of 2cm equals to 0.4 liters of air expansion. Assume room temperature to be 25 degrees C and car running temperature to be 90 degrees C. Also assume that your hoses is infinitely elastic - thus pressure in the rerservoir stays constant. thus V1/T1 = V2/T2. T1 = 302K. Ictcx.
