Paul R Posted August 19, 2003 Share Posted August 19, 2003 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. Link to comment Share on other sites More sharing options...

Ian C Posted August 20, 2003 Share Posted August 20, 2003 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? -Ian Link to comment Share on other sites More sharing options...
Paul R Posted August 20, 2003 Author Share Posted August 20, 2003 Suppose i need to get this sorted before I start modding it then? Would it be a good idea to fit a boost guage? I should be able to tell if I'm losing boost then? Paul. Link to comment Share on other sites More sharing options...
SkyJawa Posted August 22, 2003 Share Posted August 22, 2003 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 So sorry, no help, but hopefully someone might know what to look for - I'd like to know too!
