2013, by then clios will be cheap enough to modify properly.
As it stands, they are about 10-14 days from completion, but even then we wont have the immediate time to do an installation as we are so busy with already comitted work. Development programs dont make money but it sure does spend...
rs inlets are better, and are larger throughout, so you cannot modify them in exactly the same way as the non RS ones, even with the same program they will come out difference as material placement is different.
We are writing a new program to see if we can improove the RS manifolds a touch...
A manifold and remap doesnt quite come in at the same budget as cams/labour and a remap, so its not something i would advise. Trying to swap a sale from £500 to £1600 isnt very polite imo.
Its perfectly fine for John to express his feelings of the work carried out on his car, it keeps us all humble and striving for more.
He doesnt need my concent to say what he wants.
Unfortunatly not all cars gain massive amounts, and 5-8bhp isnt going to make your hear race as you can...
yea, i can sort it out and put up visual graph comparison so its pretty easy for anybody to spot the difference.
Typically when you compare cams you use the figures starting at 1mm or so lift, this eliminates the ramp area and you can better judge (from a peice of paper) the valve...
they use differing start lift points for their cam data so its hard to compare direct.
lift/duration graph is the only way, like i said, i'll doctor up a set if fred sends me a pair.
then months become moooooooooooooooooooooooooonths.
The stock ECU will only run/idle ona fairly mild cam as its sensitive to manifold pressure fluctuations. So basically, as wild as you can run on the stock ecu without any stalling issues.
Schrick do 1 profile that idles on it, cat do a...
I cant say exactly which one is 'better', i do not have the lift/duration data off the schricks as i've never measured one completely, i've only had the chance to do some very basic measurements on them.
But if fred wants then i can doctor up a schrick and overlay the graphs so people can...
Thats not very good or fair, you cant go saying 'i wont compare dyno figures or even take notice of them' then stick up two cam data sheets which are completely different.
The schricks are obviously giving absolute figures whilst cat are giving figures at 0.1mm minimum, so that will exclude...
ultimately, the megane, but at considerable cost.
The williams head is the cheapest option for 95% of the gains you need.
Current development has allows us to generate higher flow from the williams head than the 172 head (in mildly modified trim with larger (33.5mm) inlet valves), at sub...
excluding the cams and valve springs.
The heads are the same base casting, but the williams has 31.7mm inlet valves vs the 1.8's 30.7, same exhausts.
The williams also has a secondary machining operation done to the short side radius.
Apart from that, exactly the same.
