I was driving my 300 auto over the weekend,and noticed when the tubs kicked in there was too long a delay before the second turbo kicked in,

Im ashamed to say its been like it a while.

So last night whilst in bed i thought about the car instead of sheep (as you do) and it suddenly came to me f***ing transmission fluid :smash: anyway topped it up today.

Made a huge difference,am i lucky or could i have caused damage? the car drives and changes gear much faster and the delay i was having is no longer there it has always changed smoothly and still does.

Lack of oil is always dodgey, especially as the autobox on these cars is a bit of a weak point, keep an eye on the oil level and see what colour it is, should be reddish, if it goes brown and smells burnt could be a bad sign I am afraid.

long a delay before the second turbo kicked in,

 

Errol,

 

Just to clarify, the turbos in our cars work simultaneously and therefore spool up at the same time. There are only a few twin-turbo cars ever produced where one turbo spools up before the next. In the case of the Bugatti EB110 there were four turbos (!) - two small ones which spool up first and then two bigger ones which produce the bulk of the boost. Your turbos should therefore never spool up independently of each other.

 

What you've been experiencing is probably a slipping clutch due to either low fluid (which reduces the oil line pressure) or burnt fluid (in which case you should have a slipping clutch all of the time). As has been said above, check the colour and smell of the fluid. Although this isn't a fool proof way of diagnosing burnt oil (some oils will only change colour if/when things get really bad so don't go on colour alone).

 

HTH.

Very true, Mine was still red and did not smell when mine died. was not untill i striped it down that i found the black oil. Usualy from what i can tellfrom striping down mine and rebuilding it. low oil will burn out the high clutch plates and/or the front planatay gear. but as you say its changing ok now it should be ok.

Thanks for your reply guys i think i may just be lucky, silly me always thought one turbo spooled up before the other,learning all the time ill keep an eye on it thank you.

Heh heh, you have a 300zx mate not a Supra TT. They have sequential turbos.....
