Renaults figures are indeed at the fly...and his figure is an estimated flywheel figure. All Renaults are down on factory figures...some more than others. Youve just got to live with it and not get upset when u go on the dyno!

Thats basically what you do.

I cant say ive ever bought fastners from B&Q tbh!!!

local fastners suppliers? B&Q even.

what do you wnat to know?? From that list Chipwizards fills both parts of what ive stated above. There is no definitive answer.

I can supply pistons and post them to you.

Mapping is only as good as the person doing it....so the answer to your question is: whoever has the best understanding of what they are doing, and the most experience doing it.

Basically the only real way to get this car running sweet on those cams is to have an after-market ECU controlling the engine, which ISNT running MAP for load correction. Its either that, or they change the cams for a profile suitable for OE managment.

Its not really anymore complicated than force breaks things!! Its also likely that most Jap engineering is better than most we see on road cars...e.g out good old French 'boxs. For a given engine speed event?? That wouldnt be true. Increased ignition advance due to increased knock limits...

can u read?? "Mitsi LAncer Evo" adapt to run just FWD and bingo bango. few mods to driveshafts and you away. use your imagination lad. and as above...TORQUE kills a transmission...NOT power.

Possibly cheaper option would be use the gearbox from a car that runs higher torque in standard form...e.g. Mitsi Lancer Evo....something thats designed to take it.

I know

i'd rather have 5k in my pocket.

full load yes....revs not so much. yup u want (as it always should be) the oil to be fully hot. give it bursts of full load in say 3rd and 4th, then let her over run. do this for a while then change oil.

revs dont matter so much when ur adding inlet pressure! then again, neither does displacement lol

How much have you just paid?..if u dont mind me asking.

Their aftercare service is spot on aparently!

How many gearbox u seen with bearings and synchro's on the OUTside?!

Finally

Peak power and torque will typically be shifted up the rpm range with higher duration. Actual performance will be dependent primarily on open/close points, lift@tdc, and peak lift. With 290deg duration on stock managment you *may* encounter idle issues due to ECU running a MAP sensor. Likely...

I agree with that...you do want mounting plates welded in.

gearing massivley effects acceleration. A gerabox is simply a torque multiplier. it takes the torque from the engine and increases it by whatever ratio gear you are in (inc final drive). hence why u accelerate better in 2nd than 5th.

Nope...we've already established torque brings accln! IF an engine produced 200bhp at 3000rpm AND 7000rpm....the torque output would have to be differnt for each engine speed...meaning accln WOULD be different.

Power is a function of torque and speed...so those two extreme examples would yield different power output.

tbh mate i havnt read the whole thread, and im not quite sure what u mean. if u can explain some more...

lol...also...strictly speaking... never mind!

However its worth noting... If in the case of the flat torque curve yielding "constant accleration"...it wouldnt strictly be constant in practice. Wind resistence will increase with velocity, therefore the opposing force increases with V, so accln decreases. strictly speaking!

He's right Edde lad... Torque from the engine/transmission gives tractive effort at he driving wheels. this exerts a force on the road, which exerts an opposite force. Net acln is related to the difference in force exerted by the two bodies. Mathematically...(as above) A=F/m TE It is...

well ive given you the information. if you have to try 1000 times your doing something wrong :)

What your asking in your two points is one in the same. There is a WHOLE big can of beans that can be explored here, but in simple terms... when an engine is running throught the rpm range when ur foot is flat to the floor (or at any throttle angle for that matter), imagine the engine...
