remap complete......wow!!!

[HarveyGTI]

i dont get the max flow rate argument? when tuning, your tweaking boost but thats not the only factor you use to change/increase the powerband. then theres engine condition. boost isnt the only variable.



a true custom map suited to an individual engine is always going to do better than a generic one. whats generic for the lcr? 260? give custom map a 5% gain on a very good engine and youve got your figure.

jabba have never run my ko3s over 1 bar to get 242 with just a sports cat. so its not just flow rates. ive twice seen people leave there with just ok results dyno wise

im over the moon to have a jabba 320bhp dynoplot, but it wont be 320 next time even on the same rollers. too many variables. so its a guide only


if jabbas rollers are generous wouldnt everyone get great figures?

Trauma, I think, and I think only, that the max flow rate is to do with the actual physical limitations of the turbo

i.e. only getting so muc power from a turbo, due to only being able to physicially flow so much air, therefore equating to a K03s managing 250bhp or there abouts as a maximum (with other mods of course)

mind you, when you throw in other aspects, such as how healthy the engine is, sensors, mafs etc etc, this can play a factor in how well the car will tune

Ahh the Dyno Lottery strikes again!

complete **** why does everybody dout jabba's RR is it because they have REVO?
i drive an ibiza and am always told how jabbs rollers over read until i proved it on a RR that normally is referred to as giving a low bhp reading but it still pulled the expected results of 249 bhp. which is deemed impossible by REVO die hards

lol, spot on Karl

I have NEVER rated revo, and NEVER will, from personal experience of having it on my old Ibiza

there is no comparison to a tailored map if you have other mods to ensure you get the most out of your car

Jabba IMO are still and always will be one of the best tuners around, and when my Ibiza was tuned by them, the results were pretty spot on, as proven when going to other RR's, as all RR's produced similar figures

Nope i am ex jabba But like i said, dont believe everything im told

Would always opt for jabba over revo

I recorded 274bhp with a ''custom'' jabba remap. (Just remap) A week later at JBS RR day, the car recorded 261bhp with EXACT same setup and actually cooler conditions. I dont think an LCR managed 274bhp even with exhaust and filter that day.

So the generic vs custom argument doesn't say a lot here

If to argue the point custom is better, i would then peg generic maps at 255bhp and custom maps a little higher at 260bhp.

No way will just a remap get 270+ GENUINE bhp

Argue til the cows come home, it aint happening

Max bhp for K04 IS 280bhp, lots of tuners will tell you exactly the same, as does the manufacturer You aint going to get near this figure with just a map though, needs exhaust and filter also You can possibly extract more if inlet/exhaust manifolds are changed as you are then improving airflow characteristics but this 'debate' isn't about that, its about remapped LCR figures on standard setup.

PLEASE READ. NO-ONE IS SLAGGING OFF JABBA

 

[Mitchy]

For example if my transmission had zero loss then I would record better figures than someone with 20BHP transmission losses (unless the rollimg road can calibrate this exactly). If the frictional losses were also less in the engine (BP claim BP ultimate does this!) then again more BHP. What about if the A/C is switched off (this looses power too), I could go on....

No it wouldn't.

Your flywheel figures would remain exactly the same, your @ wheels figures would change.
Hence why LCR's have better wheel figures than TT's and S3's who run exact same engine/turbo.

 

[HarveyGTI]

lol @ Mitchy

how many times have we seen these convo's.....

But the RR must be right surely....(joke)

The conversation always divulges into this when people post up their RR figures pmsl!

 

[sparky22]

i only posted my results coz i thought you'd like to no what i got but i have to say im disappointed with so many neg posts, am over the moon with the extra performance whether its running 260ish like a couple of u reckon or 276 which is on the graph i value experience thats why im a member, but at the end of the day every rr is different and at my next oppertunity i got to do a rr then i will let you guys no what its running then, but i can imagine it wont be to much different than wot it ran on tuesday!!! thats my view i didnt post them to cause am argument next time i wont bother coz it sound to me that half of you arent enthusists like you clam to be and just come on the forum to slate other poeple rather than give friendly feedback and advise!!!

 

[Mikey_H]

well said sparky, and Mitchy i was half expecting a cocky reply from you, but you still havent proven to me or anyone else that its jabba's rollers being to high and not someone elses roller being to low? all i will say sparky is jealousy is a crule demon!!!!

The fact a K04 turbo produced 300+bhp on jabbas rollers says it all. (search for songmans thread pre ihi)

Not going to argue any further, when you've been here 3 yrs re-open this thread

Jealousy Im running well over 300 in my LCR

just ignore it mate, i generally do, its just the normal "dyno lottery" brigade putting in their opinions each and every time someone posts up their RR result....shame really

Sparky, as said in a previous post, well done mate

dont take it too seriously mate. you have a fine map and a powerful car. stick around on this forum and it wont be the last you hear of figures being doubted. take with a pinch of salt.

be happy with your dyno and power. driving it is more fun than a bit of paper anyday.

when my ihi conversion was mapped the rear bumper started melting........ who needs graphs

enjoy your map

 

[traumapat]

how do you know its running that? dyno lottery? might be 299

 

[RobM]

What makes me laugh, is those who dismiss the whole 'Dyno Lottery' theory are often the same people who, when they find out their car doesn't produce the figures they were hoping for, blame it on 'Dyno Lottery'.

It's only Dyno Lottery when you don't get the figures you want...... Or is it?

 

[Mitchy]

Might well be mate, might well be

 

[lofer]

Is there actually an accurate way of measuring the output of an engine then?

 

[m0rk]

whip it out and connect the crank to an engine dyno

 

[lofer]

So on one of those the same engine would always give the same reading?

 

[lordgibbness]

You'd still have the same issue regarding calibration.

Measuring at the flywheel would provide a manufacturer-type figure (the HP/PS ratings they are advertised at) as measuring at the wheels loses 10-20% through the drivetrain (clutch, gears, diff).

All it takes is for the rolling road to be calibrated regularly - having a known force applied and making sure the reading is accurate.

But engine testing on a bench has less variables than on a rolling road. There are more things on a dyno that need to be considered and much more scope for variations in power. Why do you think the same rolling road can produce three different results, on three consecutive runs on the same car, with the same dyno operator at the same time? There are too many variables for a rolling road dyno to be accurate.

like Mike and others said mate dont let anyone get you down i was there with you and we both saw the plot and heard what Mike (jabba ramap guy) had to say, just a shame on any forum people are always very quick to put others on a downer they cant just be happy for you, Me you and Mike know your car is like a rocket and thats all that counts mate.

With regards to this airflow issue i will be interested to find out what happens when i go to jabba on the 7th as i have a K03s turbo in my Golf and am currently running 200bhp with pritty much every performance and cooling mod i can think of so we will see what jabba get out of my car then we can all sit down and have another stupid argument about figures & jabbas rollers and you can all try and put me on a downer.
