Tuono V4, Austin Racing full system, PC5, Dyno Curve

[Mibridger]

Hi Guys,

I have posted a power curve for my Tuono V4 which now has an Austin Racing full system and a Power Commander 5 fitted.

The graph shows the output as standard, then with the half system, no mapping and finally with the full system and PC5 with custom mapping.

I am really pleased with the results, it pulls much better in any gear, and with the revised gearing (16/43) it makes the ride interesting :)


Cheers,

Mark.

[Micke65]

Really nice info , tnx !

[RoteEddie]

Do you have the Race ECU also, or have the mapping been applied to the standard ecu?

[Mibridger]

No,

Standard ECU with a modified RSV4 PC5, there is not an official PC5 for the Tuono yet.

The Tuono has only 4 injectors, not 8 like the RSV4 so no need for the SFM.

As far as I know, mine is the only Tuono V4 with a PC5 fitted.

Kind regards,

Mark.

[V4TUONO]

Mark,

Where did you fit the PC5 on your V4R and was the 16/43 gearing ratio recommended or just something you wanted to try?

Thanks
Steve

[Mibridger]

Hi Steve,

The PC5 is fixed to the battery with double sided sticky pads, The toolkit had to go :-(

I changed the gearing having read the various threads on this site, taking 1 tooth off the front would be too big a change and adding one tooth on the back means you can keep the standard chain length and slightly shorten the wheelbase.

I am looking at changing the chain/sprockets for a 520 conversion next.



Kind regards,

Mark

Hey Steve,
Good info, thanks for sharing. By the way, I changed to a 44 tooth sprocket on the back and I really like it, better than changing the front sprocket IMO and the standard chain still fits.
What are the benefits of changing to the 520 chain and sprocket? Isn't it a smaller chain? If so, wouldn't the stock chain last longer with more power? Just curious. Cheers.

[Hyper]

A good 520 chain is considerably lighter than the oem one and has less friction , absorbing less power . ( barely noticeable on the dyno ) And yes it last for shorter mileage :-)

[Hyper]

Very good numbers, i'd be' interested in seeing a graph with a race ecu instead of he pc5. The 'hole' from 6 to 7k seems to be quite important and heavier than stock, maybe with futher tuning on the pc5 can be solved

[Mibridger]

I don't think so, Rich had The bike on the dyno for 3 days so it's as good as it gets now.

Maybe the race ECU would make a difference but I don't think so.

I'm really happy with the power now, the Tuono is more about torque than top end like the RSV4, it would take a lot of work to get the top end from the RSV4, cams, injectors, head work etc.

I might try a 44 tooth rear sprocket when I do the 520 chain conversion :-)

[RSV4ME]

Wow, big jump from 6k to 9k in the torque!!! Nice...

[Rugbydawg13]

Nice boost. Now get you an ultralight battery (just got an Alien Motion for $120) and you can keep the tool kit again.

[Mibridger]

Good call, was thinking of doing that too, cheers.

Mark

[Mibridger]

Hi,
Is it the AM8 Or the AM12 you have fitted ?

Mark

Nice boost. Now get you an ultralight battery (just got an Alien Motion for $120) and you can keep the tool kit again.

Or mount the PCv sideways down the side edge of the battery, rather than flat along the top/front of the battery. Just give the battery a nudge along and I think you will find it will fit.

By the way, I note there was a decent jump in HP and torque with no PCv and just the slip-on. How did it feel with just the slip-on as it seems like a lot of extra money to buy a PCv, get a custom map and a full system.

And totally not noticeable on a street bike.

[Mibridger]

Yes,
You're right, but you don't know until you try it do you ?
Mine is the only Tuono V4 with a full Austin Racing system and also the only one with a PC5.
Although the actual numbers are not that different, it's much more fun to ride the power delivery is great now.

You pay your money and make your choices.

Of course you could get the full Akrapovic system and the 'race' map, but mine is a custom map for my bike, which is always better.

Mark

[scott2ride]

What mods did they have to make to the pcv?

[V4TUONO]

Always great to see people trying different things on the V4T Mark and I totally agree with you that a customised map is the best way to go!
Steve

[Micke65]

What about this mod , you should try this ..
I'm doing my bike up in stages and have my own dyno (dyno jet 250i) so I can see the progression. I have a 2012 RSV4 Factory ARPC. All runs were made in Track mode.

Base run was 156.02 hp and 74.5 ft lbs of torque

I added a BMC RACE air filter

Now is 159.82 hp and 78.4 ft lbs

I have posted a power curve for my Tuono V4 which now has an Austin Racing full system and a Power Commander 5 fitted.

Awesome post.

[scott2ride]

Hey Mark. Did you ride it at all with just the AR GP2 slip-on on the bike?

Just wondered how it felt by comparison.

[scott2ride]

Hey Mickie. Where did you get the bmc quote?

By the way, RSV4 filter doesnt fit the Tuono V4 without modifications to the airbox.

On the other hand, the RSV filters DO fit :)

[duck21]

I find that the bike with akra slip on and factory remap is more than enough power for road riding. I run out of road and space long before i hit any performance limits of the bike.

[Micke65]

Hey Mickie. Where did you get the bmc quote?

Next door :) http://www.apriliaforum.com/forums/showthread.php?245896-How-much-HP-and-torque-has-YOUR-bike-got

[Mibridger]

Yes, but the Tuono air filter is different to the RSV4 :-(

We tried to fit an MWR filter but they are completely different.

I believe that Pipercross does one for the Tuono V4 but I will probably wait until BMC makes one.

Thanks for the advice Micke65.

Are you sure all the settings were the same ? I have never known just an air filter change to make that much difference, normally 1 - 1.5 BHP gain is the most you will see from an air filter.

Kind regards,

Mark.

[Micke65]

Hi , are you shure about Rsv4 filter doesn`t fit Tuono v4 ...


Check here ..http://viewitem.eim.ebay.se/Sprint-Filter-Competition-Luftfilter-Aprilia-RSV-4-Tuono-V4-R-air-filter-racing/110827311489/item


Im curious about this .. My bike only have an LeoVonce factory II slipon with everything else stock .. If i put that filter in my bike without mapping does it runs lean ?

IF thoose figures a right say 3 hp gain from filter and from your dyno showed an massive ca 8 hp gain it would be about 11 extra hp without any big effort :happy:

[Mibridger]

Hi Mike65,

Well Richard Austin got the MWR filter for an RSV4, when he fitted the Austin Racing full system and the PC5, he said that the filter would not fit.

He had got the filter in specially for me, I am sure he wanted to sell it to me ;-)

I have read that BMC does make a filter for the Tuono V4 so I will try to find one of those (FM563/08 RACE)

Since it is a long way from where I live to get to a dyno shop, (I don't have my own DJ 250 like you) ;-) I am thinking I may not do it as it would require a remap.

I am pretty happy with the performance now.

Kind regards,

Mark.

Cheers,

Mark.

[Micke65]

Oki Mibridger , seems like there are diffrent filters .. but i think its wierd . Why bother to differ them ..

Well ,

Googled and found this disturbing info about airfilter in Rsv4 ..
When I pulled the lid off the airbox, I made a disturbing discovery: While the RSV4 uses a quality K&N-style cotton-gauze air filter, Aprilia leaves it dry to improve airflow. That’s fine on a racebike that will have its engine rebuilt every season, but insufficient protection for a bike expected to last tens of thousands of miles. With no oil on the gauze to capture dust, the inside of the airbox was coated in a thick layer of grime that extended down into the velocity stacks. Yikes! After washing the airbox and cleaning and oiling the filter with K&N filter oil ($8.18; www.knfilters.com) I drained the contaminated engine oil and changed the oil filter. If you own an RSV4, oil your air filter ASAP!

Can it be the same for tuono or did this guy just be unlucky , they forgot to oil hes ex ..

Is it hard to open the airbox , anyone ? :)

Did chage on my Ktm Superduke 990 .

[scott2ride]

I haven't looked, but if be surprised if the OEM filter requires oil. They are normally paper & not reusable.

Glad I read this thread though as I was going to order the rsv4 bmc filter for my Tuono.

[Hyper]

every rsv4 filter is usable, but since it's a bit larger in size , you also need to change the plastic support and frame with the rsv4 ones. ( cost around 10 euro ) . I have bought the parts but finally mounted the sprintfilter that does not need to be oiled , using oem plastic frame ( that is the same filter for older v2 rsv, at least for this brand of filter)

he tuono oem filter is a standar paper one. And is not difficult to change. Just take the tank off and unscrew the top of airbox cover, moving the cables and the ecu on one side , no need to take the ecu off the cover .

Yep the RSV will fit?

Which is great as I have some spare new RSV BMC and DNA filters kicking around.

[Hyper]

The Sprintfilter for rsv does fit , so i suppose also other brands can but i'm not 100% sure. If u have one spare around, just try and let us know :-)

[Micke65]

Nice info Hyper , tnx !

So you went with the sprintfilter.. not bad , maybe i will too , later on :)

[scott2ride]

Ok lads. This weekend I'll chuck in a filter from an RSV & let you know how it goes.

[Joely Boy]

Hey Scott, when I was doing the research into the air filters from memory both BMC and K&N quoted the RSV part number for the V4 Tuono. Mine's still in the box for now, wanted to get the mapping done first.

[swannie007]

Hey Joely Boy, Get that mapping done! Best thing I have done to my bike yet. You will be well pleased. See Sean at Brisbane Aprilia aka Springwood Suzuki. He is a good guy and has done a few so he knows what he is doing. You need to take your bike around so he can get some numbers off it to send to Italy to get an unlock code. Normally gets the code back in a day or two and then you take your bike back to get the map loaded. Takes about an hour.
By the way, let me know if the K&N filter fits as I have one in my garage and need to fit it but don't want to go through all the hassle to open it all up to find out it doesn't fit. If memory serves, K&N quote the same part # for the RSV4 and the TV4. Anyway, let us know.

[scott2ride]

Ok guys.

RSV1000 air filters fit beautifully. Use them.

RSV4 air filters dont fit. Go figure!
RSV4 filters can be made to fit but you need to buy some parts from the RSV4 air box. See my thread on Performance Mods for the part numbers :D

[Joely Boy]

Thanks for the heads up Wayne. I rung them a couple of days ago and they said no worries, bring her on down. Just have to find the time during the week to get it done. Can't wait to get it mapped and bang the filter in. Now everything has settled in I'll have to set up the suspension as well.

Cheers for confirming the filter to Scott. I ended up ordering mine from Latvia and wasn't real keen on trying to send it back.. lol

[swannie007]

Hey Joely Boy, My pleasure. I have fitted my oil filter and it was a no-brainer, looks schmick! By the way, RSV4 air filter doesn't fit right in. I'll have to order the RSV4 bits to make it work.

[Hyper]

One info: are you getting the ecu unlock code ( normally given only with akra by Aprilia exhaust ) also with other slip-on brands ??

[duff_boy]

What's this swannie? Did springwood suzuki remap your standard ecu with race mapping? If so... how??!?!?! and How much did they charge you?

[waterwolf]

Could some pls explain to me the difference (if there's any) between the race ECU and race mapping that goes together with Akra slip-on from the dealer?

[Hyper]

Same exact thing. The race aftermarket ecu is needed only if you dont buy the akra slip-on from the Aprilia dealer

[sidewaysammy]

Can you post a pic of the pipe...................on the bike please

[Gabro]

Ciao Mark!
could you take the dyno *drf files?! shold be intresting to compare them with an RSV4 dyno
