    SRi-T cooling light and possible losing boost

    got a cooling light on my new car, wonder if its because the aircon doesnt work? or is it something to do with the engine cooling as the fan comes on at around 92 degrees which i believe it to be ok but it only stays on for 2 mins when idling, is that right?

    also on the car i brought it had some proper sheeeeeeite cone filter (still standard crossover pipe aswell) with a poor cold air feed, and a poor boost pipe and a weird dump valve connection, and i have unbelivable loud chatter (exhagerated through the cone) and it doesnt feel 100% on boost, almost jerky or am i expecting it to be faster than what it is? has a front mount and cat back exhaust.

    just to add i have no fault codes after doing the pedal test.

    My SRi-T electronic cooling light comes on most days at the moment. Need to investigate further!

    Got a standard airbox for sale mate

    But seriously, you're only in Oxford so i could come help you with the dump valve setup if you like? Took me ages to get mine setup in a way I liked it! Jerkiness will more than likely be because of the dump valve, I've just disconnected mine and it's soo much smoother!

    yea will i live in didcot mate so 25-30 mins from you, may have to have the airbox if i keep the car, although i was thinking of getting the 2.2 box lol, and the boost pipe set up isnt great its like 3 or 4 pipes joined together i wonder if i'm losing boost somewhere through a connection? as i get hesitation at around 3.5-4k revs, and also it feels very sluggish low down the revs not very torqy i dont get it

    Do you have a picture of the boost pipe setup? It sounds like the OE dump valve may have a one way valve facing the wrong way, causing it to stay open and hence loose boost.

    i have no pics yet lol i'll take some as soon as i can. Although i took the whole top hat to intercooler pipe set up and reattached it alot tighter and the car rund smoother but still dont like the way it boosts lol i went for a quick drive and it still hesitates everynow and again...

    although i got 0-60 in 6.7 secs on the trip computer earlier
