I think there was a guy on here running 220bhp but his gearbox blew!

Mine is running 175, up from 136....it's enough for me

Re: who has got the most powerful 2.4jtd 10v engine?

I think its the torque that blows the gearbox.. not the power so good chiptuner and torque around 380nm and then over 2500rpm-3000rpm more power out ..( torque is going down ) . I think that clutch and gearbox would be ok...

btw.. how fast your car is... I mean around 100kmh-- 160kmh for example ? standard 150hp model goes around 14,5 sec .( 0-100 9,4 )

Re: who has got the most powerful 2.4jtd 10v engine?

I have been told by a well reputed Tuner, that pushing the power of the 2.4 10V to 200 bhp requires it to be a low miler(below 50.000km) or thoroughly renovated/Rebuilded to cope.

With 100.000 km+ 175bhp should be top setting. With 200.000 km+ it should not go beyond 160 bhp.

Re: who has got the most powerful 2.4jtd 10v engine?

I m sure that he tould you why those are top settings ? because I dont get it..if you are using 160hp/1bar ( standard boost? ) and you get 200 000km... and then 1.1bar and 175hp and 100 000km . and finally bigger cooler front new exhaust .. lower intake temperature and 1.4bar boost +200hp and under 50 000km ? now that has to be joke. you dont have to drive it every day like you were on track. I m having over 300hp on my Q4 and I still run on standard clutch and no problem... now I want to now whats the first that brake down on the jtd 10v engine.. because if you say clutch...that can be programmed by chip..

and what about this: squadra-tuning are selling 180hp/380nm chip = so under 100 000km and angel tuning are selling 200hp chip.. now thats gonna blow right away and madeno racing sells also 200hp kit... so thats gonna be just a joke..

I just think he has a conscience, and does not want people to break their engine/drivetrain. You seem to be forgetting we are talking about a Forced induction car. Any fool can tune it untill something blows. I dare you to stick in the 200 bhp/435 Nm chip you talk about in your 2.4 10V, turn the steering wheel to full right hand side lock, press the gas pedal to 2000 Rpm and drop the clutch.

Re: who has got the most powerful 2.4jtd 10v engine?

well I tested it with 1.2bar ( about 280hp ) and it goes 0-200 20,8sec and the figures are at the moment 324,3hp/421.6nm . I have new injectors waiting.. and then the exhaust manifold . after that new dynotime. and 100-160 kmh was 6,5 sec.. and for peter... why on earth I would do that. Im not that stupid

Re: who has got the most powerful 2.4jtd 10v engine?

it seems that the 200-220hp is the most powerful.. and 430nm+ torque. and also seems that 166 jtd 6-speed gearbox is stronger . hmm but how much 166 jtd clutch can hold ? and are drivetrain etc stronger than 156 ?

Re: who has got the most powerful 2.4jtd 10v engine?

hmmm just thinking. new turbo ( garrett gt 23v ) good for 250hp, new exhaust, bigger frontmounted cooler, and custom chip ( under 2400rpm 400nm max )and I believe there will be good every day car +220hp / 400nm torque . with bigger turbo : temperature is smaller, boost is smaller. new exhaust : pack pressure is smaller. bigger cooler : intake temperature is smaller. custom chip : we can choose the maximum torque that the clutch can hold . so what I m saying is that whit just a chip I think the 2.4 diesel will brake earlier than whit other mods too .

Re: who has got the most powerful 2.4jtd 10v engine?

yep.. little problems.. its maybe difficult to reach over 210hp with original injectors and 1350bar fuelsystem. so with bigger injectors and 1600bar system or just bigger injectors.

that 160bhp figure seems a little low, considering standard they have
150bhp.
normally anycar should be able to handle a 10% increase, which
would make that figure 165 bhp.
As for enginelife??????? 160bhp or 175 bhp or 200 bhp will not make
much of a difference to the engine block, really.

you also must remember we are talking diesels, not petrol turbos, and
as a diesel runs with an excess of air in the first place, then you
have to realise that tunning to 165/175 bhp if done properly does
not involve a major boost of the turbo.

also if you decide to upgrade the intercooler, then again you already
have a possible 160bhp plus car, without doing anything else to it.
so how anyone can claim it has an effect on engine,is behind the
times.

Any real problems involves the turbo, which is not the engine and
badly done remaps with spikes.
and yes the clutch can be an issue due to the huge amounts of
torque, but as has been said already, a good tunner would be able
to dial round this, to a degree...

Re: who has got the most powerful 2.4jtd 10v engine?

finally someone how underastand me ! Im trying to tell people here the same thing.... I have been talking with "squadra tuning".. and he think that replacing the injectors would be enough for +220hp level.. and I believe that if chance the turbo bigger one + all others what we have been talking about then maybe we can reach over 230hp ! only that my dream is good working 2.4 jtd 10v 100hp/ 1.0l so it makes 239hp, but it also means that if that hp is coming about 4000rpm then the torque will be 419,5nm . but so high rpm, I dont think thats a problem, and some good tuner will but that torque smaller

Re: who has got the most powerful 2.4jtd 10v engine?

We regularily do 200bhp and 326lb ft on the "150" 10v 2.4 and have had some clutch issues on high mileage examples (where the clutch was probably due a replacement anyway) but apart from that, there have been no issues.

We run 3 x 2.4 JTD 10v's ourselves and have tested many many tuning options on them. We have indeed broken a gearbox on a "140" 10v when it was "tuned to the hilt" and was running more stupid power than we would ever contemplate on a customers car - which is why we try these things out on our fleet anyway. We found that 365lb ft torque and figure of eight wheel spins in 3rd do have a detrimental affect on a gearbox. The clutch was perfect though!! We have detuned this one now to around 315lb ft and it has done 120,000 miles and is still running without missing a beat and regularily does 500 mile trips in a day and returns 40mpg. It also runs on bio diesel quite frequently, still does customer demo drives and is used on a daily basis. Who said Alfa's were unreliable!!

PS - to go from us oldies quoting lb ft to Nm multiply it by 1.36 :-D
