Fed up with turbo lag!

Anyone else find driving a Supra through urban areas and/or at times when you need a short spurt are a PITA with turbos. Lag, lag, lag and the moments gone.

 

I've been driving a works car (Golf TDI) and I love the instant response from the throttle. It makes driving in traffic so much easier than wait for it, wait for it, wait for it, BOOOOOOMMMM! and then hard on the brakes!

I kinda (and I say that in a 'I wasn't really trying THAT hard and my girlfriend was in the car too' kinda way) got left behind by a new BMW 3somethingsomething. It shot off up the road and while I reeled it in eventually I can't help but think it would have been easier without Teh Lag!

 

He also overtook a car and tractor on a blind bend so, y'know.....

Would you really want that amount of power from a standing start though? We'd be reading even more incidents of Supra owners spinning and crashing their cars...

Who said anything about standing starts?

 

You know what I mean though, anything up to say 30/40mph.

 

I've been left by some pretty mediocre cars (all overtaken at higher speeds however). I put it down to my crap driving though.

Are you running yours in TTC mode then? I don't have any trouble getting mine to work (sequential) when I want them to. Either put it in manu mode, or just drop it into 2nd. Its surprising how fast you can go in 2nd!

 

Get those revs up! :)

Gearboxes are cheap anyway, all the auto > manual lot can't even give them away.

 

Depends which auto box you have. ;)

 

It catches me out too sometimes Martin if I'm not expecting it and don't have time to switch to Tip mode.

I loved the NA for around town, pulling out of junctions etc. I'm a lot more cautious in the TT.

Is yours decated Martin?

 

IME the responsiveness improves dramatically once it is fully decatted and running higher than 1.1bar. You will still get that 'lag' scenario when you're caught in the wrong gear though, but that’s what you get from having a high geared 4 speed car and a 'tiny' 3 litre.

 

From what you've been saying for a while now it sounds like you want high torque available in almost any gear. There's only one way to get that - big CC's :D

You folks seem to have a different understanding of the word lag to mine.

 

True; was going to mention it but realised I don't know what to call it.

 

Is lag is the time it takes for a turbo to spool to full speed when exhaust gas flow is readily available?

 

What would you call the delay in a compressor creating positive boost pressure due to insufficient exhaust gas flow? (such as RedM is describing)
