HI people just had my car rolling roaded at shark performance and it made 215 bhp with a custom code remap pi flow intake and milkek cat back a new revision d dv , shark said there was no boost loss So just wonderi g if any one had any problems or any ideas on why I could be sooo down on power??
Cheers andy

Do a search for Custom Code. They aren't the most liked of mappers. :wink:
-
Could you please clarify what car you have...
-
Oops sorry gti 20t 200 bhp one

Oops sorry gti 20t 200 bhp one
Then wow, something isn't right... :confused:
-
Was that at the wheels or the flywheel? as the Bapro dyno is a coastdown dyno, and most people on here quote at the flywheel figures?
Did he ask what map was on the car before he ran it?
-
In numbers wouldn't the expectation be for 235hp+ as a rough figure at the fly with given setup?
215hp would be the expected figure of a nicely running k03 GTI with an a/mkt exhaust only, from my understanding.
-
215 to fly wheel and 340 nm of torque
-
340? :confused:
-
340? :confused:
Indeed!
340Nm is only 250lb ft.
-
340 nm =250 lb so that s about right for a mapped car ai t it ?
-
It seems strange how the torque is what you would expect but the bhp is down shark did say there didnt seem 2 be any boost loss either so dunno realy , the problem could av been easily diagnosed if the car had had a before and after rolling road 2 see if every thing was running correct they said they would do that when I booked in but did not then remap time came do to the rolling road man not being there , so il give them a ring 2 see what they say, not 2 impressed realy but could be nothing (hopefully)
-
Ah yes of course, I confused the units

the bapro gives both wheel and flywheel power on the graph.

I dont think they work like that tbh. Ive seen two revo stage 1 cars make 240hp on his rollers now, and considering they see themselves as the alternative to REVO and a direct competitor, you'd think hed'd do it with them, and not Custard code, who lets be fair, dont exactly have a 5star reputation
-
I wasnt incinuating anything Sy :laugh:
I know some people have confused flywheel figures with at the wheel figures before, I've done it myself before :rolleye:
Wouldnt have thought Ben would try underhanded tactics like plugging his own maps at RR days, although I've been to two RR days where the operators have been on a sales pitch!
I had the same thing happen with my shark stage 3 map making 286bhp at the last dyno day on Dyno Dynamics rollers, I havent got any boost leaks, and that made 350bhp before :stupid:
I have no error codes, only a spot of overboost and some timing pull, so make what you will of that one :popcornsoda:

Hi peeps I rung jbs about my car said no probs bring it in Friday for a look at it so will see what they make of it then it just seems strange how my torque is up and so in my mpg but only 215 bhp , and ben from shark only asked about my mods after the 3 runs they just said it was smooth but should be producing more power
-
Just back from jbs said everything is fine and the rolling road fans must have been 2 small so my car over fueled 2 compensate hence the power loss :confused: now I am confused
-
No way. The fans at Shark are the most powerful that I've seen at a rolling road, so they are talking rubbish.
Did they not do a rolling road at their place then, as you were promised one when you got the remap done, so in essence they still 'owe' you a run on the dyno?
-
No rolling road just took it for a run re checked everything said everything correct said the result was wrong / cheep rr etc so I dunno just drive I suppose
-
Dyno wars :grin:
temperatures are usually printed on the dyno graphs so you should be able to see them. Without a big high pressure centrifugal fan the TFSi is hard to keep cool, my old axial fan used to struggle sometimes (no axial fan will never make the pressure of a similarly sized centrifugal fan) so I bought the biggest fan centrifugal fan that DynoDynamics sell, problem solved.
Ideally the car needs running on the dyno and datalogging to see the actual intake temps.
-
In all honesty, those fans do shift a lot of air, so that's a lame excuse. You could always pay for a run on a dyno dynamics rolling road before you go back, at least youll have 2 different dyno results to prove to them. other results were accurate at their Rr day? It was a brand new bapro dyno, and they aren't cheap!

Off topic here but when did JBS go APR :surprised:

Maybe after awesome dropped em

Thats carp. Allans vRS with revo stage 1 made 240hp/313lbft on their bapro dyno on the open day. And quite a few others made 235hp+ on stage 1.
Those fans are mega powerful.
Fwiw ive had my car on 5 seperate dynos now( 4 x dyno dynamics and sharks bapro twice )results were 210hp/208hp/213hp/211hp on dyno dynamics rollers and 211hp/206hp on sharks rollers. Id say their pretty spot on personnally, and your issue wasnt heat soak

Cheap is one thing it definitely wasn't.
I know on the day you asked me about some of the petrol cars making lower than expected figures, later in the day we had a 2.0TFSI with our Stage 1 map on it with no problem. Unfortunately I think that was the only other Stage 1 TFSI that was on the rollers that day, but we have had other TFSIs from other days with other maps that have made near enough the figures they should have done :happy2:
The fans are twin 3kW pushing 38,000CFM, they're pretty adequate for most cars.
