290BHP on the wheels!

[peternofx]

Gents for your info:
Pretty good I think to get 290BHP from the V6....

 

[blakey]

It is good, get some info and pictures up

 

[peternofx]

I hope the picture from the BHP print-out is visible?

So far I know It is a Clio 255 from Germany.
Re-mapped by the Dutch company Fastchip (very experienced and good company for re-mapping fast Renaults)
The Clio has home made 280 degrees camshaft with a longer stroke of the crankshaft....
The print-out was not finished yet, next time they suspect to go to 300BHP on the wheels....

Would be great to see whats been done exactly to get that sort of power. Most, including myself will doubt that graph is anywhere near true if it has only had one or two modifications. However, if the crankshaft has been stroked and cams changed I should imagine the joblot has been fettled with in which case it is beleivable. I look forward to seeing it! :approve:

 

[Adrian]

It is true Brett. It is stroked to 3.3 ltrs. Was done During a dyno meeting of the dutch Renault club.

I'm rather wondering at the AFR and its similar shape to the torque curve. If that's anything near true it's either a very badly tuned map at the beginning of the project or if it's final then the tuner is neither very experiences nor very good...

Yeah, thought it would be pretty seriouse kit. Would love to see it in action.

Can the gearbox handle that much torque?

^the standard diff won't!

why doesn't the power and torque graphs cross at 5252rpm? I'm a little unconvinced by that graph

 

[EEE007]

The gears themselves will be fine , as for the bearings , nope .. Week point on standard power, the box needs heavy duty bearings and prob quaife LSD. And additional bracing on casing wouldn't go amiss.
Most probs on PK6 series g/box are due to bearing failure/wear then the play causes synchro issues and finally gear failure if unlucky or ignored

As I understand, the mapping is still in progress. I don't know if he is still running the standard gearbox. Heavy duty gearboxes are availble here at Veban Motorsport. The casing comes from the Renault Master which can hold bigger/stronger bearings including a Quaife diff offcourse but I'm unsure if he's on the standard box or not.

And to be honest he uses totally different camshafts so the curve could differ from a normal clio

Can't see that. The Renault Master can't handle the torque of its stock tdi engine. They are so bad that our local commercial dealership advised a friend not to tow anything with the fleet he bought from them!

 

[Adrian]

I'm not talking about a standard Master gearbox here... Only the empty casing/housing/shell of a Master gearbox.

The rest is custom inside. MK2 gears, bigger/better bearings, Quaife diff and so on... It has proven to be a good custom box. :approve: :race: 350NM+

 

[Brett]

Sounds good if that is the case and it being worth it regarding cost. I was looking into modifying a pk6 box an awfull lot but came to the cunclusion I was barking up the wrong tree as a rating off sub 280 lb/ft is piss poor in my veiw.

 

[Fred]

EDIT, graph is scaled wrong hence why it doesn't cross at 5252rpm

 

[teun]

cool!

 

[peternofx]

EDIT, graph is scaled wrong hence why it doesn't cross at 5252rpm

If I look on the pic its going to 7450rpm......
So I don't understand....

 

[Fred]

power and torque are on different scales if you look up the sides of the graph

 

[Grippy255]

At the graphic is also markes that this V6 is 3.3 liter now.

 

[k1ano]

Always was 3.3 - first thing I noticed from the original post :approve:
