really!
Thats a first for me!
All this malrky over RON, its makes little difference.
Besides, all this quoted RON is useless without any other info on MON, or even if the RON is the MON/RON average.
As i said earlier, the clio trophy cars make 285 with a renault sport twin TB, twin plenham, new ecu, std engine with new cams and valve springs, new exhaust and thats it. The std inlet manifold is quite a horrid thing......a spiderweb of bits.
So, headowrk, twin plenham setup, different cams...
They crashed a laguna V6 into the back of a clio......if it were my company i sure as hell wouldnt let it go out with such simple to sort fixes. Despite what Ren could of said.
90K isnt a high milage engine, its just entering puberty.
a good semi of sull synth 10w40 for winter and 15w50 for summer is fine.
ELF comp semi from ren is both cases is great, castrol is fine, shell helix, total is fine, most oils are fine. Just when its a cheap oil its a cheap oil. The...
as with all cam timing the simple basis is increasing the duration that any one valve is open during its component stroke the more air your can get in (forget fuel as its not a primary function you need to worry about) and the more air means more VE, the larger the VE the larger the torque...
indeed, the std head is far from crap.....its good as far as a cast and robotically machined head goes.....not as good as honda performance heads, but good.
ANyway, work the inlet manifold (even with the tidier casting its still w**k), some headowork.....not truely invisible, but unless the...
best you can do is a search as its been talked about a million times, or read one of the current threads.........gets tiring posting the same thing day in day out.
there isnt much you can do to the inlet manifold apart form matching it to your current inlet port and doweling it. THe runners are lerge and unrestrictive apart form teh shape which is spiral and impossible to work on apart from the last tight radii and where it meet sthe port roof and floor...
NA trim without too much work, 320-350bhp is fine and not really overly stressed. If your pumping it out and no cost issue then 500bhp+.
Add turbos to the equation and build strong enough components......hell, why stop until you break the 1000bhp marker.
nothing really special to getting...
Um, not as such.
If you want to make life easy use some white marker paint and mark your own reference points in straight verticle lines for the timing. APart form that a normal belt change.
Actually hearing pinking when running is hard, its a semi mettalic rattling noise as the piston rattles in the bore going over TDC, usualy due to too much ignition advance, but your knock sensor would detect this unless faulty.
