toyotasupra1980 Posted May 16, 2009 Share Posted May 16, 2009 At jap fest today i decided to put my supra on the dyno for the first time, people were were asking me what to expect and i said would be happy with 400bhp and the least being 380bhp, paid my £45 the guys setup everything stuck my car on the rollers and off it went , the result an impressive 385.1bhp running at 1.1 bar of boost and 344.9 ftlb Torque, considering its an auto and running on stock ceramic turbo's and still with 1 cat on i am very happy and its powerful.:D:D:D Quote Link to comment Share on other sites More sharing options...
tooquicktostop Posted May 16, 2009 Share Posted May 16, 2009 Good result with a Cat still in, what were you EGT's at WOT on 1.1bar ? Quote Link to comment Share on other sites More sharing options...

Having a CAT in at 1.1bar will cause higher Exhaust Gas temps, not 90 but around 700-800 oC is expected, any higher could be an issue Quote Link to comment Share on other sites More sharing options...
supra matt Posted May 16, 2009 Share Posted May 16, 2009 would of been in the hundreds mate would of thought around the 950 deg c + with that spec . Quote Link to comment Share on other sites More sharing options...

You don't know that mate, with a cat fitted and the boost your mention the egt's could (and will likely) be through the roof. You *need* to decat when raising boost that high. Do not take shortcuts or you will seriously shorten the life of your engine. FFS, how many times do you have to be told this! PS: I couldn't care less to be honest but it's just a shame that you are likely to be damaging your car for no good reason, other than listening to this supposed "expert" tuner which no one has ever heard of before.

Ahh ok thats fine then, they checked the AFR's and EGT's at 1.1 bar on WOT, thank goodness for that Quote Link to comment Share on other sites More sharing options...
toyotasupra1980 Posted May 16, 2009 Author Share Posted May 16, 2009 Ahh ok thats fine then, they checked the AFR's and EGT's at 1.1 bar on WOT, thank goodness for that all precautions have been takn to make sure she is running at a safe level, powerfull but safe, i have used the information about going bpu from this owners club the only thing i have not done is go full de-cat it does also include the re-strictor ring to stop the boost from spiking.

Mate first of all I am not having a go, not at all, Take it from an owner who has lost an engine it is not as simple as an MOT and service station saying all is ok when they have no EGT and AFR data, I am sure you are seeing high EGT's with a Cat in, this IS a risk thats all, if you are happy to up power at this risk fine, thats the risk you take for the gains !

You didn't follow the BPU guide then. You need to remove both cats, or have a 2nd high flow cat. Was the guide not clear enough? Quote Link to comment Share on other sites More sharing options...

No in short I would say your current 1.1bar 385bhp could be a risk now, I would get the 2nd Cat out now add a restrictor ring then get an AFR gauge to be safe beyond stock boost Quote Link to comment Share on other sites More sharing options...
Scooter Posted May 16, 2009 Share Posted May 16, 2009 if you were in my position what would you do? do you have a boost controller thats upping the boost to 1.1 bar or has it just gone up to this from the one cat being removed? Quote Link to comment Share on other sites More sharing options...

Ok if you like, that has nothing to do with the safe running of your engine now though does it ?, 1.1 bar with a cat in is a risk and any garage worth its salt would have told you that rather than pushing BHP Quote Link to comment Share on other sites More sharing options...

How do you know its running 1.1 bar without a boost gauge then? I would be very careful with your right foot until you get A full de cat An AFR gauge An EGT Gauge A boost controller A boost gauge Quote Link to comment Share on other sites More sharing options...
