Guest Usmann A Posted April 24, 2003 Share Posted April 24, 2003 Hi everyone, I have heard of magazines and numerous reviews that claim that power falls off in 2nd gear, I thought they were all talking rubbish. Until a few days ago when me pops took the car out, after a month, and when taking it upto the local stretches, the car would pull fine in 1st, then in 2nd it would struggle, just make more noise and not going anywhere fast, then when selecting 3rd the car would come alight again, with the usual head hitting perfomance, as* 1st displayed. What do you think this could be down to?, is second not that much of a strong gear within the supra, or do we have a fault? It was drvien maxing out 1st gear.. The boost gauge was reading the normal .9 bar boost, but seems like their is no boost? Cheers! Any advice appreciated! Quote Link to comment Share on other sites More sharing options...

Ian C Posted April 25, 2003 Share Posted April 25, 2003 Did you change up from 1st at or around 4000rpm? -Ian Quote Link to comment Share on other sites More sharing options...
Guest Usmann A Posted April 25, 2003 Share Posted April 25, 2003 No, me dad kept the 1st floored all the way to 6800, as stated before.. Quote Link to comment Share on other sites More sharing options...
Syed Shah Posted April 26, 2003 Share Posted April 26, 2003 How much (if at all) did the boost drop? Did he shift slower than usual? If you shift slow, you tend to lose quite a bit of boost, and in lower gears, there is not much time to spool again before shifting again. Maybe a leaking BOV?

Guest Usmann A Posted April 26, 2003 Share Posted April 26, 2003 He was shifting very quick, and the BOV is an HKS item, didnt notice any drop in boost gauge, as the greddy gauge was reading .9 bar all the time. Seems odd...... Quote Link to comment Share on other sites More sharing options...
easyrider Posted April 26, 2003 Share Posted April 26, 2003 This is the same thing that happens to scoobys-on scoobys its supposed to be an emmissions type thing and only happens when the ecu sees that the driver is holding it in 1st gear longer than normal,it then makes the boost solenoid cut boost for second gear-this only applied to std ecu's and was easily overcome by upgrading the ecu or even easier by fitting a bleed valve/dawes device. Maby this sheds some light on the subject???? P.S-i know they are 2 cmpletely different cars before anyone says it;) Quote Link to comment Share on other sites More sharing options...
Guest Usmann A Posted April 26, 2003 Share Posted April 26, 2003 Thanks, but that concept is silly, because the ecu shouldnt cut anything as long as you stay within your rev limit,6800. Cheers for this info....anyone else have anything.... Quote Link to comment Share on other sites More sharing options...
Syed Shah Posted April 26, 2003 Share Posted April 26, 2003 Well, if boost remained a 0.9bar all the time, I reckon you were just feeling it (after reading reports that 2nd is a poor gear). The only other thing I can think of is maybe your dad was not on WOT? Quote Link to comment Share on other sites More sharing options...
Guest Usmann A Posted April 26, 2003 Share Posted April 26, 2003 umm. I know he was on WOT, but it really felt slow like no turbos came online,and was making a loud noise, but not going anywhere....but he gauge was reading fine...will try again...

Syed Shah Posted April 26, 2003 Share Posted April 26, 2003 Yeah, do a few 2nd gear pulls, and keep an eye on boost etc. Post your findings. Quote Link to comment Share on other sites More sharing options...
