The Automatic Performance Thread


Recommended Posts

Recently, people have been going one of 2 routes with automatics.

First is to convert to manual.. easy to do as there are plenty of party lying around the import yards.

The other option is to beef up the auto slushbox and love it for what it is!

That's what this thread is about...

NO automatic haters

NO more wondering the potential of the automatic

So what i propose is that everyone with an automatic skyline post up your dyno figures and real 1/4 times (not g-tech figures!) and i'll collaborate the figures into the first post as much as i can... that way we can have an overview of how the auto stands on the track and what power is required to make different times..

Finally somewhere to compare auto figures, as most things you will see on SAU are for manual cars and don't 100% correlate with automatics...

So here we go:

rb20 - R31, R32, or cefiro.. stock = 100rwkw

DYNO

185rwkw - RB120WHY

179rwkw - AnFz

170rwkw - WazR32GTSt

165rwkw - RSTME

139rwkw - Nizmo_freek

1/4

11.08 @ 113mph - RB120WHY (with slicks)

14.6 @ 98mph - WazR32GTSt

15.0 @ 108mph - AnFz

rb25 - R33, R34, or Stagea..stock = 135rwkw

DYNO

317rwkw - dangerman4

255rwkw - Abo_Bob

244rwkw - lukits01

229rwkw - wildr33gtst

229rwkw - DivHunter

225rwkw - satantic

220rwkw - 4door_sleeper

203rwkw - pkblade

203rwkw - SECUR1TY

193rwkw - judd33

187rwkw - Haines

185rwkw - MacGuyver

181rwkw - Fly_with_sky

176rwkw - 666DAN

166rwkw - so_tred

160awkw - Tangles

160awkw - AlexCim

146rwkw - Basti

142rwkw - Howie

1/4

12.3 @ 113mph - Fastrotor

12.7 @ 106mph - Abo_Bob

13.0 @ 105mph- 4door_sleeper

13.0 @ ??mph - lukits01

13.5 @ 164km/h - judd33

13.7 @ 101mph - Haines

13.8 @ 101mph - SECUR1TY

14.2 - Alexcim

Hopefully a moderator can sticky this and it can be kept as a valuable resource and i will try to update weekly or even more often

Please try to refrain from general chit-chat, but feel free to discuss engine, suspension ,and trans mods that have been made to make the above times and figures ;)

cheers,

Warren

PS.. the only rules are:

- must be a nissan transmission

- must be original displacement motor

(basically an original car but modified..)

Ash,

i have a few isseus with that thread...

1) never updated

2) contains manual and auto figures

3) hard to find

i really want to separate the automatics and have a thread devoted to the slushbox so that all information can be correlated without bias

i have an auto and yes there is potential trust me i out run manual skylines with even afew mods while i'm running pretty much stock but as i'm not looking at big power n fast times i will be converting to manual becoz i miss the clutch lol...

any1 looking at fast times dont let the name auto fool u trust me u can get very fast times with autos

Heres my old cars results,i never got the chance to dyno it after the gtr fuel pump, R.I.P.S intake plenum and greddy profec B specII set to 13psi so i dont know what it wouldve been after those mods, have since sold it and bought a "MANUAL" r33 gts25t lol, the r32 went pretty good for an auto actually

1989 r32 gtst auto

standard everything apart from:

2.5"slipt dump pipe

full 3" exhaust

cheap as pod filter (no cold airbox or heatsheild)

600x300x76 FMIC with 2.5" piping

stock boost (11.2psi then drops to 9.2psi after 3500rpm)

139.7rwkw

No track available near Adelaide atm - so no 1/4mile times

Stagea RS V Four, 86500kms, automatic, RB25DET engine, Attessa 4wd

New Oxygen sensor & New 400amp battery

Davies Craig automatic transmission oil cooler upgrade kit

Whiteline front and rear adjustable swaybars

Whiteline front castor kit

Whiteline rear subframe alignment kit

Bilstein front and rear suspension shocks, with ‘lowering’ circlips, using standard springs

Maltech front and rear stainless steel braided brake lines

DBA slotted front rotors

Bosch 040 fuel pump with direct battery feed at 13.8volts

Nismo adjustable fuel pressure regulator

Nissan Z32 Air Flow Meter

3inch JustJap stainless steel single dump pipe system

3inch Catco high flow catalytic converter

3inch Dayz edition(?) cat-back exhaust system with quiet muffler

K&N pod filter

Cold Air Induction box with direct air feed

Hybrid dual stage Electronic Boost Controller, set to 10 & 12psi

Apexi 'hybrid' front mount intercooler with custom dodgybrothers pipe kit

Apexi boost gauge

Apexi SAFC Super Air Fuel Computer

Apexi SITC Super Ignition Timing Computer

R34 GTT 17inch rims

Hankook K104 tyres, 235/45/17

160 all wheel KW @ 12psi

Soon to be added, most likely towards the end of the year:

MV Automatics auto transmission valve body upgrade

Hiflow turbocharger and a dyno retune, at 1bar

Expect 200 all wheel KW at 15psi - dont know what sort of 1/4 mile time that'd produce, probably 14's due to the weight of the Stagea.

:D Brendan

keep those figures coming guys!

don't forget to sepcifically mention if you have any work done to your atuo as well as any engine mods

i personalyl have done to my trans:

- 2800rpm high-stall

- stage 2 shift kit

- trans cooler

although the first 2 were not in when i recorded the above figures..

I ran 15.01 @ 108mph. 60 ft was 3.0+. Very hard to get any wheel spin / momentum of the line

Car was making 179rwkw (untuned)

HR31 GTS-X

RB20DET Silvertop conversion

GT2871r @ 15psi

Walbro fuel pump

FMIC

Pod and steel intake

Adjustable fuel regulator

I don't think you ran 108mph mate.

I have run 12.7 @ 106 with 255rwkw.

I suspect that for some time now I have been getting more power on the dyno than on the road because I think a restriction is created once I lower my bonnet.

Auto has been fully rebuilt by Mike at MV Automatics in Adelaide. Uprated valvebody, kevlar bits and bigger servo's etc etc. Stall caonvertor is something like 1800 but the flash speed is the same as the stall speed. Normally the flash speed is lower.

Stock auto, panel filter, full zorst, 12psi

Same mods plus Powerplay ROM tune:

New tune, 480cc injectors, GCG highflow turbo, FMIC, blew the auto transmission at this point:

The engine was then rebuilt with Tomei type b Poncams and the below 255/256 dyno sheets are for this stage.

Timeslip

UAS dyno run 256rwkw

Bel Garage dyno run 255rwkw (same mods as UAS one)

Then I converted to manual for a bit of fun.

I think I know what I ran. But having said that, perhaps I could say that you dont have a true 255rwkw. 1/4 mile times, dyno figures...they are all things we can measure, but sure as hell sometimes they cannot be accurate 100% of the time

I would say that my dyno reading is slightly low, as duty cycle on the injectors was reaching its limits as was the AFM...so I would expect peak power to be slightly higher.

Also I presume you have an RB25...your dyno graph shows a lot more power down low compared to how my turbo setup responds. I'll try to get a scan of mine up to show you what I mean :)

It pulls like a steam train in 2nd and 3rd....all power made medium to top end.

At a recent drag day, I was reeling in rexies mid track that were making 13sec passes. I always ran out of track though (800m might tell an interesting story!). So that figure I believe to be more or less accurate.

Abo Bob's problem is the dead spot between 3,250 rpm and 4,500 rpm, as can be seen in the UAS dyno graph. It is killing his ET and TS, hence not representative of his true 256 rwkw potential.

:P cheers :P

Sorry mate didn't mean to be offensive. I just meant that 108mph sounded about 8-10mph too fast for the ET and power.

I might add that I'm hopeless at the quarter mile. Always have been.
