Power then no power??

Hi,

 

I've noticed a few times with my jap import supra tt auto that I keep losing power??

 

Sometimes when I floor it I get a big kick, other times not a lot seems to happen, but I can still hear the first turbo kick in and feel the second kick in at 4k revs.

 

Whats going on?

 

I noticed today that there was lots of power when I booted it from an almost standstill - infact the car shimmied and the back end slipped out for about 3 seconds when I was accelerating, until I bought her back in line again :-)

 

After this I parked for about a minute to pick something up (left the engine running). I went down the same stretch of road and floored it, no wheel spin and a noticable amount of power loss..wierd.

 

Also it doesnt always seem to kick down - what could cause this?

 

Is all of this releated to heat build up? the engine is totally un-modified as yet - could the cats be causing the problem?

 

Cheers,

 

Paul.

Well, if it's unmodified it shouldn't be drawing in heat from the engine bay due to a pod filter, and that effect should only be apparent in the initial launch.

 

It's not fuel vapourisation as you didn't stop the engine.

 

It could be a slightly dodgy hose leak, dumping a bit of boost?

Mine does this on the very odd occasion. I have a boost gauge and hit 1.1-1.2 usually, a few times I've gone to boot it and the boost has been about 0.2-0.4, if I take my foot off and back on its fine :confused: So sorry, no help, but hopefully someone might know what to look for - I'd like to know too!
