As the thread states...
Just wondering what the highest rwkw anyone has got with just the standard mods being: exhaust, CAI, diff, and edit?
any takers??
What you should have asked was - who ran their car on the happiest dyno...
You'll not get a useful answer.

At a dyno day with 40+ other cars i got 241rwkw (best was 243rwkw)
Ive seen a few in the low 250's but generally on cooler days than QLD has. Anything from 240-260rwkw from bolt-ons is considered good. 220-240 the norm and 200-220 towards the lower range.
As Elmis said though, Dynos are different, temps and sensors placed in different spots, atmospheric differances, differant fuels, additives, happy dyno's can all make the figures fluctuate a LOT. Some cars might run lower on a Dyno but still be able to get GREAT 1/4 mile times. (Markone2 is a classic example)

Sorry mark, but here i go again...
Markone2 ran 12.5 @ 110mph (give or take a pubic hair) with 219kwrw, i, along with HEAPs of others have more (235kwrw) and couldnt pull that off as its all in the tune :bash:
The moral of the story is: High figures are for bragging rights only, MPH is the shit

:) Quite right..track mph tells all......in this case 12.231@ 112.42mph with 219rwkw....and another young gent from Sydney town is about to knock that for a six with 222rwkw in his VX SS

Carl,
all i can say is u hit the nail right on the head,i was at wsid and saw a car that thought he was making 245rwkw on a unopened engine,he ran 102mph :eek: i think more like 180rwkw and a very happy dyno...

With a 215rwkw my car did a 12.8 at 109.8 so dyno means nothing to me, only mph.

Mine is somewhere between 212 and 235.
Runs 13.3 consistently.Been on 4 different dynow with 4 different readings :lol:

In reality a dyno is a measuring tool used for testing & tuning.For example we had a car come in the other day that had apparently made 250rwkw on another dyno.After running the car on ours with the owner watching in accordance to Exact Dyno Dynamics shootout regulations we saw a maximum of 221rwkw.
A message to everyone out there DON'T BE FOOLED BY INFLATED DYNO FIGURES.THE RACE TRACK/MPH IS THE BEST DYNO.
We are planning to post up some educational info on dyno testing with comparison graphs etc using only one car very soon.We hope to show people,especially newbys how figures can be inflated & explain why it can happen.

Iv'e done lots of testing in this regard around adelaide and G@D in melbourne.. at the end of the day use a dyno that your comfortable with and stick with it...... As Glenn said, they are just a tuning tool and the peak figure isn't the most important thing.... The average power or area under the power curve is... MPH is a great indicator...
I should also add that G@D were very good and their dyno gave the exact same figure as I got at west torrens in adelaide..

Heres how i see it, do 160km/h and stick you head out the window :lol: Dyno fans dont come close, leave the dyno's for the tech guys, tuners, engineers etc, the rest of us can all keep our ET/MPH, or otherwise just be happy with our rides :D
BTW, You will probably break your neck if you stick your head out the window at those speeds :teach: Atleast you would probably make the darwin awards...

Hi all, You guys are making me feel better now. My car has a lowish, 208rwkw. Its an auto, maffless tuned, with mcai (2nd hole mod), K&N filter, GTS maf pipe, Pacie Try y's and twin 2.25 system. Dyno was done in 3rd gear (1:1) and it was only 1,700 kms after it got rebuilt. I'll have to take it to the real dyno then I guess. :D (MPH)

Three different dynos and the same figures +/- 1 or 2 kW on all....our forum sponsors are a good bet :D
My car doesnt exactly rate with the big dyno numbered cars either, but its strong on the road where it counts for me every day...
My car has been on 2 dynos, both within +/- 2-3rwkw. I also have heard that some people who get new dynos, that sometimes they arent calibrated properly giving off wrong figures, but when you also hear about cars not being strapped down and different ramp rates and shootout modes well the mind boggles.

Perhaps a better question would be what was the best RWKW difference from stock to modded on the same dyno. Allowing for slight variations in temperature and calibration of the dyno these figures would probably be more consistant.....ie VYSS 195 before 225 after on dyno 1 and 205 before 235 after on dyno 2. Still ends up being a 30KW gain. It would also be interesting to see how much difference there is between tuners and hardware.

i got 255rwkw with zorst, cai and edit. no diff gears. and i haven't run the 1/4 yet, so no times to back it up...

Ok no offence - but this is a good example of what a lot of people are talking about in this thread. I very much doubt you really have 255rwkw - if that were a true reading then you are talking about similar power to what most people are getting with usual bolt ons plus a small/mid size cam (212-220-ish duration).
Get it to the strip - if you do in fact have the power the dyno told you, then you should be seeing a mid to low 12 second run and 112mph+ trap speed without too much effort (ie, stock diff gears, stock suspension, no stally if auto, no slicks needed etc etc).
People reading this should not expect to get 250+rwkw from the bolt on mod path! As others have stated focus on 1) the % *improvement* over the baseline run, 2) strip performance and mph and 3) driveability and seat-o-meter improvements.
Cheers,
Beej

Well said Beej... You have a piece of paper that says your car had 255rwkw on that day on that dyno Rogue.. yes your car sounds fantastic and goes great and your very happy with it.. But the numbers are pretty much just numbers, without trying to stir remember Bill Towler's?? Both your and my cars ran numbers far below what we had seen at other dyno's that we have used. And we probably have used dyno's that read higher than others... Take it out to the strip and see what numbers you get....

I agree. Not to put down the dyno results, but I got a dyno sheet reading 252rwkw too. QTR times didnt change fmo the 228rwkw I got previously and the MPH was still around 106mph. If the intake charge is too high temp. the Dyno Dynamics software readjusts incorrectly, or so Ive been told. Either that or the Dyno was'nt properly calibrated, but I doubt that as its maintained by Dyno Dynamics themselves. Have'nt had another Dyno run to back that up, but I dont feel the need to, as I already know the track times.

Well gee willikers... it appears i DO have 255rwkw...
And as for Bill Towlers dyno, i've never been dyno'd on another dyno ANYWHERE that inserts blocks of wood into your jacked up suspension, and then straps it down so tight on the rollers that you can hear the axle groaning....
And yes, Tuna and Doughy tuned my ute, so if you don't believe my dyno sheet, give them a call. :D

The problem isn't with dyno figures on printout/screen captures it is with the inconsistency of dyno results. For example - I used to race an R6 - on a Dynojet Dyno I only ever manged to get max 108RWHP yet on a DynoDynamics Dyno I got 120RWHP. I too have an old dyno sheet somewhere with this result. My bike wasn't any faster than the week before but with a supposed 11% increase in power I should have been blasting by other guys I raced with every weekend. It didn't happen and next dyno was on another Dynojet and only showed 106RWHP.

We have plenty of customers bolt on cars that pump out 250 rwkw plus.
The highest we have seen is 259 rwkw and this car backed it up at the track with a 12.5@114mph with street tyres in a full weight sedan on pump fuel.
Have seen 268 RWKW on a Dyno Dynamics Dyno with the car pulled onto the front roller then drop back to 243RWKW
when strapped hard into both rollers.They now have new software as used in the latest dyno comps to combat this problem.Not to many shops would have this new software.
To sum it up if you have a M6 with 250 RWKW it should run 110 to 114 mph.
Auto is much harder to get a gauge on due to stall conveter , etc that can rob power on the dyno and mph.
Hope this helps out.
Cheers Phonsy
I have run a best of 112mph some bolt ons have run 114!! i range from 240-250rwkw i know one making over 260!! (no not me) Phonsy does some great things with bolt ons and cams.

MPH at the track is just another tool and can still be as inaccurate as a dyno. How can you compare the mph on a SV8 to that of a lux-0-barge. There is a 300kg+ weight differance to factor in. Not to mention driver skill, suspension setup, tyre sizes, gearing etc. At the end of the day its how the car drives and responds.
While i do believe some dyno's are happier than others, i still only see a dyno figure as a rough guide to the cars performance. A before and after graph says more about the increase. Same as a history of runs at a track showing the development and improvements made over time.

I agree 100% with you Voodoo. I have previously done a 13.385@110mph pass with stock gears with new 17" tyres yet, yet the last time i went the best i could manage was a 13.330@104mph with 3.9's, but i was using bald tyres ;). It doesnt mean i have lost power or gained any, just "other" elements effecting the outcome.

17-01-2005, 12:20 PM
I did a 13.14 @ 104.7mph
faster ET but slower MPH. Add to that a weight differance, differing gearing, driver skills, temps and track and the mph theory is out the door to determain power outputs. Im sure someone with the old 1/4 mile calc can work it out.
Still i have a dyno sheet that says 241rwkw if i need to have a online dick measuring contest :) hehe
