dude! its 8-1!

 

Well me and the other 6 or so people who have just brought pistons are all 9.1:1 which i believe is the same as what Rich is using sooo....

[Sam 4]

9:1 will be nicer engine too. 8:1 is "I drive a cosworth so it has to be 8:1" territory which means its a dog off boost.

i dont agree

 

my 2wd cossie was 8:1 which is std and drove lovely,

 

it's when you drop below this, with a badbly spec'd engine it is crap off boost

[cybernck 400 1 Cars]

T16's are also 8:1 and coupled with 4wd drivetrain and 1350+ kg's it makes for a very bad off-boost performance .

 

however, i'm sure that in a sub 1000 kg FWD 205, it would be a completely different matter!

as long as you use the right methods to stop pre-detonation you should run as high a compression as you can get away with

how's progress Garry?

 

 

It's just over 9:1.

I guess you lot haven't bothered to read the Lynx engineering Pricelists where it clearly states Wossner forged pistons for 8.0-1

 

what are those steps though Batfink? what makes a VAG 2.0T engine capable of running boost at 11.0-1 for 200bhp?

No offence intended welshpug, but best to check your facts before posting. The pricelists may say 8.0:1. The ones easypug have ordered are 9:1.

Squish height, water injection, chamber design, piston design, ignition, AFR, sparkplugs, intake temps, any hot spots, type of fuel, and the list goes on...

 

VAG engine is direct injected!

There's a very good current thread on Guy Croft's site about the same.
