brian89gp Posted August 6, 2003 Report Posted August 6, 2003 Those with a 282 tranny, at a 70mph cruise what does the tach read? Quote
LukeZ34 Posted August 6, 2003 Report Posted August 6, 2003 Anywhere between 2500-3000 RPM.. can't remember exactly. I'd go find out for you, but I'm in colorado at the moment, lol. Quote
midstar Posted August 6, 2003 Report Posted August 6, 2003 2583RPM in fifth by my calculations if you have a V6 282. 83MPH is like 3000RPM Quote
brian89gp Posted August 6, 2003 Author Report Posted August 6, 2003 I had calculated 2600 and just couldn't believe it, its so damn high. Quote
brian89gp Posted August 6, 2003 Author Report Posted August 6, 2003 Looking at it the quad4 282 gearing is much better in my opinion. http://www.brian89gp.com/other/transmission.htm I'm cringing at all the gas my engine would suck at 2600rpm 4t60e= 2200rpm 284= ~2300rpm 282(w-body)=2600rpm (yikes!) 282(quad4)= 2300rpm Quote
92turboLE Posted August 6, 2003 Report Posted August 6, 2003 Anywhere between 2500-3000 RPM.. can't remember exactly. I'd go find out for you, but I'm in colorado at the moment, lol. where in colorado are you??? did you bring the TGP??? if so, i would like to come have a look at it.. i havent actually seen one in person, just kinda want to get a good idea of what the layout is for when i start the piping for my turbo setup. - Justin Quote
AWeb80 Posted August 6, 2003 Report Posted August 6, 2003 Well, not to steal the thread, my 4T60-e runs about 2500 RPM's at 75 MPH. Is that normal, cause I can get about 26-27 MPG. Quote
Whiskey River Posted August 6, 2003 Report Posted August 6, 2003 Good grief, at 75 MPH, my 4t60 is is barely making the motor turn 2200 rpm. I'm with Brian though, I would hate to think of how much fuel my car would drink at 2600 rpm. Quote
ismellrealbad Posted August 6, 2003 Report Posted August 6, 2003 Well, not to steal the thread, my 4T60-e runs about 2500 RPM's at 75 MPH. Is that normal, cause I can get about 26-27 MPG. im almost positive mine runs that fast also. im going to be doing a hiway run tonight at mostly 75-85mph so i will post my findings. and i thought manual transmissions were suppsoed to be MORE fuel efficient??

kfahn Posted August 6, 2003 Report Posted August 6, 2003 mine hits about 2500 at 70-75mph as well (4t60-e tranny) Quote
Guest TurboSedan Posted August 6, 2003 Report Posted August 6, 2003 at 75mph in 5th gear my car would turn 2700 RPM. joshua Quote
LukeZ34 Posted August 7, 2003 Report Posted August 7, 2003 where in colorado are you??? did you bring the TGP??? - Justin Up in Longmont.. but I don't have the TGP with me. Quote
Bolt_Crank Posted August 7, 2003 Report Posted August 7, 2003 generally, in the city is where you'd notice an increase in fuel economy with a 5 speed, because you can control the load/rpms a lot better and, it's expected that a 5 speed will run higher rpms on the highway... they give better accel. although, generally, the 5th gear should be like OD with the auto tranny....

SmokesGTP Posted August 7, 2003 Report Posted August 7, 2003 My 4t60-E runs about 2300 at 75MPH. Quote
Bolt_Crank Posted August 7, 2003 Report Posted August 7, 2003 at about 60MPH, my 4t60 runs about 2000 or so RPM in OD, IIRC... it's been awhile... Quote
TGPilot Posted August 7, 2003 Report Posted August 7, 2003 Looking at it the quad4 282 gearing is much better in my opinion.http://www.brian89gp.com/other/transmission.htm I'm cringing at all the gas my engine would suck at 2600rpm 4t60e= 2200rpm 284= ~2300rpm 282(w-body)=2600rpm (yikes!) 282(quad4)= 2300rpm I would not have thought 200-400 RPM at a cruise would make that big of a difference. My little Celica beater runs about 3300RPM at 80 and gets 34 MPH on the highway. Do remember it is an 1989 geared to run the old 55MPH highway speeds that used to be posted. Maybe that is why the older GP 282 gear ratios were so high because of pre-70-75MPH highway speed limits? 8) Could you imagine being stuck at 55 driving across country now-a-days? :shock: Quote
Bolt_Crank Posted August 7, 2003 Report Posted August 7, 2003 the majority of Canadian highways are 62.5MPH, 'cept for a few in BC and the former NWT which were 56.25 now we have some that are 68.75MPH.... I want an 80MPH highway dammit! Quote
PaPaPooh Posted August 7, 2003 Report Posted August 7, 2003 Could you imagine being stuck at 55 driving across country now-a-days i can from cali half way is mountans and most time except goin down is from 45 to 65 it sucks but i got 390 a tank and it ran at 2600 or so at 75-80 Quote
sonyman87 Posted August 7, 2003 Report Posted August 7, 2003 4t60e 2k@55mph 3k@85mph is ruffly what my tac reads how fast if 4k in OD? And what is the sweet speed for highway travel? Quote
Bolt_Crank Posted August 7, 2003 Report Posted August 7, 2003 4k in OD in my Z is about 180km/h (112.5MPH) 70MPH = 2K even in my Z Quote
