Mafless & Ripshift done!!

[vxclubby85]

Finally done it!!!
Just picked up my car from APS,
Got 4inch pipe, 2 hole mod, Mafless Tune and Ripshift.

Only other mods are a 3.5" sureflo system.

Car pulled 193.8RWKW with only airbox mods and 238RWKW after tune!!!

And the Ripshift... all I can say is WOW!! definately worth the money!!
Feels like a completely different car!!!

Heres the Dyno sheet:

please correct me if im wrong
but if a commodore ss has 2 standard 2.1/4' pipes isnt changin it 2 a single 3.5 inch smaller than standard??????????? :shiner:

Hi,

How Much Better Is The Gear Changes After You Had The Rip Shift Installed.

[vxclubby85]

mate it feels like a completely different car!!
I would recommend it to anyone!!!

[SJM HSV]

How Much Was The Rip Shift (if You Don't Mind Me Asking)

[vxclubby85]

the standard pipes are very resrictive and squashed in places
The 3.5" is actually proven to flow and gives better numbers

was going to pm you but it doesnt let me

cool
thanx mate:)

[macca33]

SENSATIONAL result there mate, the car would be completely transformed I'd imagine! :bravo:

I would also bet that you are VERY happy with the RipShift option. I keep telling blokes how good they are and they are a bit doubtful. THEN, they drive a car with one installed and their reaction is..... :shock:

Enjoy your transformed rig and to the crew at APS - WELL DONE!

Cheers,

Macca

[vxclubby85]

yea loving the results!! I will recommend the ripshift to anyone!! drives so good!!!

And of course the guys at APS, Frank & Mick were extremely friendly and helpful!!! thanks guys!

Can't wait to drive it more!! :dance:

[Phonsy@GM Motorsport]

Good work guys. Glad you are enjoying your new Ripshift.
Nice power gain from the the APS crew.

Cheers Phonsy

Without doing the maths I think you will find that 3.5" is actually bigger than 2 2 1/4 x2 and flows more air.

Without doing the maths I think you will find that 3.5" is actually bigger than 2 2 1/4 x2 and flows more air.

cheers

doing the maths...

1x 3.5" = 9.62 sq. inches
2x 2.25" = 7.95 sq. inches (not to mention the squashing at places)

FYI, 2x 2.5" = 9.82 sq. inches

so it is a large gain in cross sectional area

Im interested to know why on your dyno sheet the correction factor is different between both runs.
One run has a correction of 1.58 and the other has 1.53 correction
As far as i know these should be exactly the same figure.!!

Once the correction is set thats it, it shoudnt be changed between runs and definatly not before doing the run after tuning.
This is showing a false gain from before the tune to after the tune.
To show a true gain i would of thought that the correction should be exactly the same.
I'm no expert but i know that if a correction factor is changed then the displayed results will change.

Would the tuner like to explain this please.!!!

As long as he is happy with the results ... who really cares :rolleyes: APS have the runs on the board, I'm sure they know what they are doing.

Nice result, my VYIISS came out at a nice round 240rwkw after a mafless tune, pretty much the same result that you got. Throw in a ripshift and you have a great setup that's a heap of fun to drive. Nice work.

:cheers:

I'm sure many would care.

Dear Logzy,

Your assumption comes the fact that you percieve that the correction is somehow controlled by the operator. This is not the case on a Mainline DynoLog system, it is updated continuously once the dyno is turned on by an Automatic Weather Station, so if the correction is different from one run to next, then the conditions have changed, and the Correction has taken care of this. This is what gives you truly comparable testing, if the correction had not changed, then this where you would not get a real comparison.
Also, bear in mind, the correction went from 1.53% to 1.58%, this means a difference of 0.05%, don't think that the correction changed by 5%, as that is how some mathematically challenged people would read it.
Your comments are quite incorrect and misleading, and yes, you are no expert, whoever, or wherever you got your information from has no grasp of how Atmospheric Correction works, or how it is used.

Think of correction like this, if the Ambient Temp went from 20degC to 25degC from one test to the other, then the engine is naturally not going to make the same power at the higher temp, so we correct for this, if we didn't, then the second run will not show the true comparison as it will have a correction for 20degC, not 25degC. Of course, the Humidity or Baro Pressure is also accounted for.

Dear awddynotodd,

Thank you for your detailed explination of the correction factor for a mainline dynolog system.
My apologies to you for the incorrect comments.

No problems logzy, happy to help.

Champ,

Mick from APS conducts LS1 tuning from my shop in the northern suburbs on my digital twin retarder Dyno dynamics dyno.

Mick always ensures that I have the dyno conditions consistent, so as to maximise efficiency with his tuning.

His dyno and my dyno show the same figures, and the cars on them run the numbers.

My LS1 clients are extremely happy with the quality of his work.

Back under your rock.

[vxclubby85]

just to let everyone know, i still cant wipe the smile off my face when i drive it!!

so much better!! the biggest difference!!!
well worth it and i HIGHLY recommend the guys at APS

:dance:

[SS Enforcer]

Must have been a pretty quick edit only 3 mins between dyno runs to achieve
that result.

Would the atmospheric conditions change much in 3 mins?

Or is this just just a glitch in the computer generated timings.

Just curious is all.

Like I said in another response, the difference was only 0.05%, the Barometric Pressure has to only change by 0.5mbar or 0.2Deg C or 2% Humidity to make 0.05% difference in correction.
What normally happens during back to back dyno pulls is the Ambient Temp
raises a little in the room, the room can also dry out, and this can also effect
the Baro Pressure, so like I said, it showed what happened, no glitch in the
computer generated timings.
When you next get a chance SS Enforcer, plonk yourself in front of a weather station for five minutes in a dyno cell whilst a car is running at full noise.
In a poorly vented cell, I have seen the Ambient Temp change by over 12deg C after 6 dyno pulls.
In a really good cell, things shouldn't change much at all.

[vxclubby85]

the tune was done before

and then when he was doing the final dyno runs, the stock tune was put back in and they did a dyno run, then put the modified tune in and did a dyno run.

thats why it shows only 3min apart.

cheers

What I really was questioning was the Time it took to do the base run then tune the car and do it's final pull.

3 mins seems pretty bloody quick to me, never seen a tune sucked out then new tune uploaded then a dyno run performed all within 3 mins.

I just wouldn't have thought it possible ,

cheers

Congrats on the result I am sure you will be happy with the extra grunt.

thanks, yea i dont know how i drove it before!!!
so much more power!!

It seems that you're fishing when theres nothing to fish for. As the customer has said, he is extremely pleased with the end result.
When I tune a car for a customer, the car spends the majority of the day on the dyno. Once i have achieved the best result out of recalibrating the program, I flash the original calibration back into the vehicle (which takes 38 seconds to be exact), carry out a power run, flash the edited calibration and carry out a final power run. In most cases this is done with the customer present.
I hope that clears that up for you.

(I hear the snapper is biting in the bay at the moment)

I wasn't fishing just that I have seen edits take ages to upload, but I then thought about it and realised that data transfer rates have improved heaps in last 2 years.

A guy I asked did say that he can adjust a tune in 6 seconds and approx 45 second to flash a full tune.

Look I was a bit skeptical, a dyno operator showed me how to lose 20 kw's on a power run after tuning my car he also explained how easy it was to skew before and after figures but the top figure pull will be genuine as long as the input details are correct.

Btw good job on the tune

cheers

[vxclubby85]

Hey,

You told me after I had the tune, that when I next fill her up to put in BP ultimate and maybe give you a call and bring it by on a Saturday and you would have a little look..

Didn't really notice any pinging, maybe a little on the optimax but it is 100% fine with the BP Ultimate.

[acexr8]

Well done boys great result and theres nothing like driving an LS1 after it's been edited and a Rip Shift fitted, you're whole driving experience changes for the good.

Cheers Craig

[INASNT]

So how much is the rip shift installed?

I am just down the road from APS

[logzy]

Why do all the Dyno reports here have no RPM reading, they only show the km/h ??

Who cares that the car has xxx rwkw in 3rd gear at 180km/h

It is the revs that are the inportant figures and should be show on the Dyno report.
Most dyno reports i have seen show RPM.

Could APS please explain this.

[lamont]

I'm sure many would care.

As you said APS know exactly what theyre doing !!!!!!! :yup:

Mate you sound like a real tool.As said b4 a hundred times dynos are all well and good but its on the track where it counts. APS have the runs on the board and the timeslips to prove themselves so as said earlier :idea:
back under your rock

[logzy]

Mate you sound like a real tool

Who is the tool.??, Why dont you read the question
All i was asking is why the Dyno sheets dont show RPM.
I know its how it drives that matters but wouldnt you like to know the rpm.

Go to Nispro or anywhere else that have dyno days, people are interested in rwkw and rpm.

It was a simple question, tool!!

[sostok]

just want to say that frank and mick are guru's theyve made my family cruiser into a machine to be enjoyed ...cant wait to go mafless and cam it....bloody familyies cost money though lol ..keep up the great work

[Jezza@HDTCQ]

Well done Mick and Frank on another nice result.

Im sure vxclubby85 have been enjoying his new found power and drivabilty that he got in October, 5 months ago when this thread started.
