Alex Posted December 5, 2005 Share Posted December 5, 2005 (edited) NB: DUE TO THE HIGHSPEEDS INVOLVED IN DOING A 1:1 DYNO SOME DYNO'S WON'T BE ABLE TO DO THESE IDEAL RUNS. If you wish to Dyno your Supra please INSIST on the following; Run your powerrun in the 1:1 ratio gear. This means it's running at the same speed as the engine, not under or over driven. It's therefore more accurate to what the engine is actually doing and you don't get sill conversion factors. Also confirm that the dyno is setup to immitate a straight FLAT road, uphill or down hill will just frig the figures. Manual V160/V161 6speed DYNO IN 5TH GEAR 6 Speed (V160) / (V161) 1 --- 3.827 / 3.724 2 --- 2.360 / 2.246 3 --- 1.685 / 1.541 4 --- 1.312 / 1.205 5 --- 1.000 / 1.000 6 --- 0.793 / 0.818 Rev - 3.280 / 3.192 Diff - 3.266(all TT) / 3.769(NA) Manual W58 5speed DYNO IN 4TH GEAR 1 --- 3.285 2 --- 1.894 3 --- 1.275 4 --- 1.000 5 --- 0.783 Rev - 3.768 Diff - 4.083(NA) Auto (A343E) 4speed DYNO IN 3RD GEAR 1 --- 2.804 2 --- 1.531 3 --- 1.000 4 --- 0.705 Rev - 2.393 Diff - 3.769(TT) / 4.083(NA) Auto's are hard to Dyno. You have to be in Manu mode with O/D off. You also need to start at about 3000rpm to avoid kickdown.

tDR Posted December 5, 2005 Share Posted December 5, 2005 Stickied. Auto's won't hold 3rd gear despite being in manu with overdrive off - hence the problems RR'ing them. Cheers, Brian. Quote Link to comment Share on other sites More sharing options...

TuneAgent Posted June 16, 2006 Share Posted June 16, 2006 good info Its good to use 5th gear on teh 6 speed, but most dyno owners I know prefer to do 4th due to the speed the cars can reach in 5th Quote Link to comment Share on other sites More sharing options...

TuneAgent Posted June 16, 2006 Share Posted June 16, 2006 I found that peak power staid the same but i got a bit better spool in 5th due to load Quote Link to comment Share on other sites More sharing options...

Great info Alex...worthy of a sticky im not sure the auto will kick down in manual mode though will it? Quote Link to comment Share on other sites More sharing options...
tDR Posted November 10, 2006 Share Posted November 10, 2006 Great info Alex...worthy of a sticky im not sure the auto will kick down in manual mode though will it? They do unfortunately Have been to numerous dyno days and witnessed it with my own cars and others.... Cheers, Brian. Quote Link to comment Share on other sites More sharing options...

How strange....I wont argue with you if you have had this happen, ive never experienced this my self but take your word for it!! Seems like a bit of a design flaw really, manu mode should mean manual and hold it in gear!! ive hear about changing down when the revs are too high and the ECU telling it not to shift down until the revs are lower? How bizzare Quote Link to comment Share on other sites More sharing options...
8secSupra Posted November 30, 2006 Share Posted November 30, 2006 The peak HP numbers will be exactly the same on a 6 speed if you dyno in 4th gear or 5th gear. But, we dyno in 4th gear because its a quicker pull and you dont reach almost 180 MPH as you can in 5th. Much safer on a dyno. Quote Link to comment Share on other sites More sharing options...
Thorin Posted November 30, 2006 Share Posted November 30, 2006 But, we dyno in 4th gear because its a quicker pull and you dont reach almost 180 MPH as you can in 5th. My gearing must be wrong. Quote Link to comment Share on other sites More sharing options...
8secSupra Posted November 30, 2006 Share Posted November 30, 2006 My gearing must be wrong. No, its the type of dyno. Most rolling roads in the UK are twin roller type, like Clayton or Autosport. This is a completely different mass than a Dynojet, which we use here in the US. I've just ran into this problem tuning Leon's car, there only seems to be a couple of good Dynojet dynos in the UK currently... Quote Link to comment Share on other sites More sharing options...

blancovich Posted January 21, 2007 Share Posted January 21, 2007 hey man: thanks a lot for this info, I was on a dyno about a week ago and the guy did tell me he had some probs with the set up and that he could do a dyno run on "inclined" surface. Since it sounded kinda BS, i just did not spend the money. Quote Link to comment Share on other sites More sharing options...
Guest URASaustralia Posted March 6, 2007 Share Posted March 6, 2007 No, its the type of dyno. Most rolling roads in the UK are twin roller type, like Clayton or Autosport. This is a completely different mass than a Dynojet im not a fan of dyno jets, dyna pack or dyno dynamics all day long for me. The dyno jets give 'high' readings in my experience.

Guest Rab88 Posted April 2, 2007 Share Posted April 2, 2007 I was gonna have my auto supra TT run on a dastek dyno, although, i was told that the torque converter cant handle it?? Quote Link to comment Share on other sites More sharing options...
Alex Posted April 2, 2007 Author Share Posted April 2, 2007 You can dyno an auto, but you need to use manual mode and lok it into 3rd gear as low in the rev range as possible. Any dyno operator worth his salt can do this. Quote Link to comment Share on other sites More sharing options...

Chris and Alana Posted April 2, 2007 Share Posted April 2, 2007 Iv been wanting to get my auto dyno'd for a while now since going BPU. Does anyone know a good one in the NE? Quote Link to comment Share on other sites More sharing options...
tDR Posted April 2, 2007 Share Posted April 2, 2007 I was gonna have my auto supra TT run on a dastek dyno, although, i was told that the torque converter cant handle it?? They can't do it at Dastek because the auto Supra's always drop a gear and climb out the dyno there. I think it's because of the ramp rate of the rollers being really high - they run the car up without any resistance then when they want to measure the power output they use a switch which puts the brake on the dyno, it's the equivalent of accelerating hard up a very very steep hill with 4 mates in the car towing a caravan.... the auto Supra kicks down every time without fail even with a lock up switch fitted and in use I'm of the opinion dyno figures for auto Supra's are pretty meaningless because there seems to be a lot of fudging to get any sort of figure on the roller type - a hub dyno is the best bet to get an accurate measurement but even then you have torque multiplication to consider with the TC involved.

Any dyno operator worth his salt can do this. Thanks for the thread Alex Are these figures the same for the Tiptronic? Is there any difference in the ratio's? I think they're the same box but not sure. How do you lock it in 3rd? Quote Link to comment Share on other sites More sharing options...
