Hi guys,
I\'m currently in the market for a Single turbo, 3rd gen and wanted to check a few things before I rush in and make a purchase. :wiggle
Please correct me if i\'m wrong but when looking at compression results is it right that...
* The closer the results are together, the better. (0.2/0.4 bar difference)
* 8.0\'s for a new engine
* 7.0\'s for a good engine
* Anything below 7 could cause problems?
I also read somewhere that if a 13b has been heavily ported compression results below 7 aren\'t uncommon? Is this true? I ask this because i\'m currently talking to a guy who\'s running a T78 on a ported 13b with water injection, all done by dragon performance. He said not to expect 7.0\'s all round as the engine has been heavily ported. :3Confused
Can anyone give me some advice on this please?
Thanks alot :cheers

I can soon as my street ported t78 is being tested by reworx as I\'m selling it
Ridiculous.
Have you just posted this everywhere :D. I have no idea why but it seems when you port a engine the compression drops. I don\'t understand why as I thought that pressure inside a chamber would be the same regardless of of volume of air. So I don\'t really understand why it does but it seems to be the way.
My experience is thats not true. Ive done many a large ported engine and pulled really good numbers. Theres just too many variables but i dont really beleive that port sizing is one of the major ones.
