we do everything within safe limits.
I also mentioned before its not so much how much torque but how its delivered.
If you don't push the boundries, you'll never know whats possible.
I don't want to enter into a tit for tat debate.
I too am not interested in a tit for ta debate but i am interested in is FACTS and discussion which is the whole point of internet forums. You post torque figures 60 odd lb torque higher then any other mapping company from a turbo that has been around for many years on an engine that has been around for several years and mapped by very large companies like Superchips,Revo,Custom Code etc who have been mapping VAG cars for longer then your company has probably been trading.
FACT 1 The LUK/Sachs made flywheel and clutch in the PD 130/140/150/160/140/170 has a max rating from VAG of 300lb torque or do you disagree with me on that figure?
FACT 2 Sachs and Helix make uprated clutches. Sachs has a very good site so if you click
HERE you will go to the
Sachs uprated clutch for the 2.0 PD BKD engine that is in the Audi A3 plus many other VAG models which states:
"SRE Performance Clutch Set
SRE pressure plate and SRE rigid organic clutch disc Transmittable torque 480Nm."
480Nm is 354 lb torque which is less then your peak torque rating and this is an uprated clutch with an organic disc and uprated pressure plate. You state though that"we do everything within safe limits"
"its not so much how much torque but how its delivered" well if your used to diesel tuning and want a clutch to last you should know that it`s the area under the graph that counts not the peak number. Diesel tuning is about having a smooth linear line not a huge peak low down with is bad for transmission,clutch and driveablity.
As quoted from Custom Code/JBS website:"DIESEL 2.0L EDC16 140 BHP
MINIMISING LOW RPM TORQUE SPIKES ENSURES SMOOTH LINEAR POWER DELIVERY. CUSTOM-CODE ARE PROUND TO RELEASE PERFORMANCE SOFTWARE FOR THE LATEST EDC16 DIESEL 140 BHP A3
WITH LOW END TORQUE SPIKES MINIMISED YOU CAN BE ASURED OF SMOOTH LINEAR POWER DELIVERY."
As to the torque graph i will now compare your torque to Superchips which can be seen
HERE. I will quote standard then Superchips then Evolve figures.
2200 rpm 250 lb 295 lb 310 lb
2500 rpm 250 lb 287 lb 360 lb
3000 rpm 239 lb 283 lb 310 lb
3500 rpm 213 lb
272 lb
255 lb
4000 rpm 191 lb
247 lb
215 lb
4500 rpm
147 lb 170 lb
130 lb
It isn`t a fact but in my opinion and probably most other tuners/mappers the torque graph that you posted is terrible and would not make a very good road car since your peak torque figure is just that a big peak then it noise dives. I don`t know how you map your cars but an easy way to get a big torque peak like that is to max out the injector to early so as to have an excess amount of diesel in the cylinders so when the turbo does come on boost at about 2100/2200 rpm the excess diesel suddenly starts to get burned ( not in the right ratio so hence smokey acceleration ) causing a rapid torque spike until the excess diesel is burned up in the cylinders when the torque suddenly starts to dip due to the no more excess diesel to durn.Due to the fact that the massive torque boost has caused the turbo to spool up very quickly the turbo starts to heat up making it loose thermal efficiency plus air inlet temps rise so power bombs through the floor as well.
Now i am not saying this is what you are doing when mapping but at 4000 rpm your car has about
108 bhp but Superchip produce
180 bhp.
As to your statement to me " If you don't push the boundries, you'll never know whats possible." you might want to look at my sig and look at what car i have and how it was modified two years ago which has now had a lot more work done on it and still more work to do including water/methanol injection.
As already stated i am not out on a witch hunt or some childish slagging match and have no grievance with you, i just want to talk about the fact. If you feel i am wrong about anything i have written please state why you think i am wrong and stating/including some evidence/facts to back up your claim.
