piston Posted April 24, 2009 Share Posted April 24, 2009 This might be a stupid question but isnt that going to cause restriction on the first turbo exhaust side? Quote Link to comment Share on other sites More sharing options...
ShaggyZ Posted April 24, 2009 Share Posted April 24, 2009 Rode in this car last night. He had it dyno tuned to 706RWHP on E85. The sensation of acceleration is totally different than the T67 turbo setup he was using before. Power hits early and hard, revs a little further then takes another big step in power somewhere along the way. However, it doesn't hit as explosively as the T67 and other large turbos most Supra guys seem to run - it just builds very quickly and relatively linearly. Not having one big spike in power like the big singles produce, you have time to adjust to the fairly linear power increase and the broad powerband so, in some ways, it doesn't feel as fast... which is about what I expected. It is also much quieter now than when the big single was on there. As the Woz says: "it is AWESOME." This might be a stupid question but isnt that going to cause restriction on the first turbo exhaust side? It's fine. Quote Link to comment Share on other sites More sharing options...

JustinOlson Posted April 25, 2009 Share Posted April 25, 2009 Nice work! What rpm range is that dyno run? Just trying to equate the mph to rpm. Quote Link to comment Share on other sites More sharing options...
Careless Posted April 25, 2009 Share Posted April 25, 2009 Nice work! What rpm range is that dyno run? Just trying to equate the mph to rpm. torque and rpm always cross at 5250, so that's 580-ish hp and tq at that rpm... right? heck if I know... just an observation.

ShaggyZ Posted April 25, 2009 Share Posted April 25, 2009 I can tell you he's running a 3.7 LSD R200 rear end and a R154 Supra transmission with what seem to be about 27" tall tires in the back. I'm exhausted right now so I won't go looking it all up right now. My educated stab at his speed/RPM... basically a guess at his tire size, knowing they're 275s. http://www.car-videos.net/tools/speedrpm.asp?Car=Select&Num1=275&Num2=40&Num3=17&AxleRatio=3.7&Ratio1=3.25&Ratio2=1.955&Ratio3=1.31&Ratio4=1.&Ratio5=0.753&Ratio6=&Ratio7=&Redline=7000&Increment=500&B1=Recalculate 1000RPM - 19.9mph 2000RPM - 39.8mph 3000RPM - 59.7mph 4000RPM - 79.6mph 5000RPM - 99.6mph 6000RPM - 119.5mph 7000RPM - 139.4mph Quote Link to comment Share on other sites More sharing options...
JustinOlson Posted April 26, 2009 Share Posted April 26, 2009 Anyone else notice the discrepency in the torque printed and the actual chart? Maybe the smoothing factor messed that up, but it still prints the peak spike in torque? Quote Link to comment Share on other sites More sharing options...

Maybe the smoothing factor messed that up, but it still prints the peak spike in torque? I was wondering about that myself. You can see it spike at the end, but that's really weird. EDIT: Talked to him last night about it. There is a spike at the end of the torque curve when it hits the rev limiter. He's not really sure why it does that, but he does get that peak torque number out of it! Quote Link to comment Share on other sites More sharing options...
ShaggyZ Posted April 26, 2009 Share Posted April 26, 2009 I may or may not have seen this 300ZX accelerating on the Indian Ocean last night and pulling a 2006 Yamaha R1 (Power Commander and slip-on exhaust) by 2-3 car lengths running from ~50mph to ~160mph. Quite a feat! Quote Link to comment Share on other sites More sharing options...
