Chipped

[peterh2]

Had my clio 16v for a couple of weeks now and loving it Put my foot down in 2nd yesterday and kept it there, looked down just before changing and it was doing just over 8,000 RPM and the rev limiter still hadnt kicked in?!?

Has it been chipped, how can I check?

 

[Mark]

sounds liek it

 

[Adams_16v]

id say so aye! over 8k is a very high limit though!

if thats on the williams they really dont like reving that high! you can get away with it on a valver but in a willy its a no no!

It is on the Williams.. I usually chage about 6700 - 7000.. its good, cus I can get 60 out of 2nd.. hehe.

But, I want a standard ECU.

Heard this before but why?? Basically its the same construction...

 

[u33db]

16v crank is stronger so can take it. Willy is basically a tractor - you wouldnt want to take one of them to 8k would you?

a 1.8 can rev higher because it has less stroke, therefore piston speed is lower. this means there is less momentum on moving parts, so they can rev faster/higher.

same "theory" as lightening internals

 

[william]

OK, got it... and no i dont want to see tractor revving 8k

So basically im one on a safe side cos my motor revs about 7000, and there is lightened conrods (for example), forged pistons and ARP bolts everywhere...?

 

[stan*]

if uve got lightened conrods/crank/pistons/valve gear, the engine will rev easier/higher.

similarly if u DECREASE stroke but increase bore (to re-gain displacement), it will rev higher. hence short throw cranks....

My 16v will do 60 in second at about 7000rpm. other than ktr ingnition leads, bosch super 4s and a pipercross element my engine is standard. Is this normal???

[Adams_16v]

yes

 

[peterh2]

Just out of interest whats the standard limit I think u33db said it was 7.5k to me but I cant quite remember.

 

[steve a]

7200rpm is the standard 16v red line.

 

[DeanRSi]

on the c57d lump its only 7000.

 

[BenR]

yup....i only get 7k
