Great progress mate. Looks great. thank you, i'll be happier once i got the lilttle bits, wiring finally tidied and done; oh and an MOT too then to get it rr'd also considering getting a 10psi spring rather than the 1bar one i am running at the mo as my comp is about 9:1 which will mean my engine wont last long. i do have a new old head that i will send off to get worked by the magical ppl on this forum but all in good time :) |

Wastegate chatter myth
There is confusion in the automotive world about so called "wastegate chatter" or "turbo flutter". A noise created on lifting off the throttle in a turbocharged car, commonly described as a chipmunk or a rattlesnake, is often stated incorrectly as being a result of the turbo's wastegate closing. The noise is in fact the air compressed by the turbo passing back through the compressor wheel of the turbo after the airflow is abruptly halted by the throttle plate closing, called compressor surge. However, in some cases, i.e. where the throttle plate doesn't open fast enough or is set up to only react to high boost, some chatter will remain. Surge can occur on diesels when the turbo is attempting to pressurize the air at a higher pressure ratio than the compressor wheel can flow at a given speed. Diesel engines have no use for a blow off valve as they do not have a throttle plate. The chatter noise is very noticeable on World Rally Cars, where anti-lag is used. A compressor stall like this can cause excess stress and wear on the turbo's shaft or bearings under higher load applications of the turbo (around 15 psi (1.00 bar) and greater depending on the trim and flow rate of the compressor side). Actual wastegate flutter occurs instead under partial boost conditions such as partial throttle near the boost threshold. It sounds like FftFftFft not ShuShuShu and is caused by the rapid opening and closing of the wastegate at boost levels near the spring pressure. It is commonly heard more clearly and may be more prominent on cars with modified intake silencers, up-pipes, and or downpipes, and is not harmful. |

so how would you set a car up to make that flutter sound then? On 10th Mar, 2012 theoneeyedlizard said:

As stated in t@z's post, its due to the wastegate opening and closing on partial throttle near the boost threshold. Sounds really good my the way. :) Edited by george91 on 23rd Dec, 2011. |

More testing needed I reckon. it did have a slight missfire on pick up near the begining! the point at which you see the camera go to the screamer is when it started to grown at me and kinda shocked me (hence the rush camera change and the coming off the throttle) as i was just trying to get it warm. needs setting up as only has the std needle in it at the mo. but wasnt run for long and the std is ok for idle. |

Don't get bolts from B&Q. They have metric and imperial bolts classed as the same thing (e.g. M8 as 5/16 unf). They are close, but they are not the same... On 11th Feb, 2015 robert said:
