dCi 105

[Swervin_Mervin]

So whats been done to get the extra bhp?

 

[Tom]

remap

 

[Swervin_Mervin]

So no boosting it to 120bhp then? Its basically a dCi 80 thats been to superchips/equivalent.

 

[Tom]

there will no doubt be other changes.

why not shoe horn the dci 1.9 in a clio. must fit as the 172 fits

There will most likly be a bigger intercooler.

Im interest though to find out what they have done to it any chnace of any insider news?

The engine stock internals should be good for the power without a problem.

Im thinking remap the 105dci and youll have 125~hp and 200lb toruque which is quick enough.

I wouldnt expect Renault to just give the car a remap as they like to leave some power in reserve like every company do (which is what Remaps take advanatge of).

There will be a more powerful version of this engine out no dought as there 1.2 16V dci engine will be the next Clio diesel engine

The 1.9 will weight to much and is bigger so safty is compromised.

They used to make a 1.9 Dci Clio (mk2, Phase1), but it didnt develop the same figures as the ones now in the Laguna etc. Oh, and btw, just because a 172 engine fits in a Clio doesnt mean anything below a 2.0 will!

The 1.9dti engine in the clio mk2 phase 1 was pretty pathetic.1.5 dci 65bhp has no intercooler,85bhp has an intercooler and the 105bhp has an intercooler and uses slightly higher boost and deisal injection pressures to gain the extra bhp.

can i put an intercooler on my 65 to make it more powerful then

The dCi 100 (its 100 not 105) has a variable geometry turbocharger, thats how it gets the extra hp over the dCi 80

 

[Swervin_Mervin]

Err, but mine also has a variable geometry turbo JeremyIt said so in your brochure when I bought it. And you can hear it from about 1200-1500rpm. The whine changes pitch and then becomes constant.



Plus how come its only 100, when the Scenics is 105? Or is the Scenics a 1.9?

 

[edde]

A variable whatever turbo wont make any more hp it may increase the low end torque due to higer potental boost with the varying vanes but thats it.

The turbo would have to run at higher boost top end to make any difference. Assuming the new 100hp runns at 10% higer pressure at the injector and the duration of injection remains the same the boost will have to be increased to ~ 1.4bar. Which would mean a bigger intercooler I would imagine.

I thourght the injector pressure they were runing at was the highest they could with the DCI system (in a production car anyway 2000bar has been done on test rigs). I take in new injecotrs are used then along with a new higher pressure fuel pump?

The 65hp could hav an intercooler fitted to it with easy as the two engines 65 and 80hp versions are almost identical. But why go for a little Renault one go and get a large FMIC one which would get you around 120hp with a one of map.

The 100 is bound to be 105~110 after beding in anyway
