err.. yes they have made a difference!!!

got sick of tootling about so I've just come back from giving the valver a quick blast.

after about 4k revs it takes off was doing nearly 70 in 2nd with still someway to go before red line! :grin:

it is fecking quick alright, but it is still smoking a bit, so won't be flooring it anymore - for at least another couple hundred miles or so anyway!

going for a compression test in morning just to make sure everything as it should be, I'm looking for about 190psi I beleive after searching the forum last night. let me know otherwise!

Hopefully it will be good news - please let the rings be OK!!! :undecided: :undecided: :undecided:

good news! Compression is good (185psi) across all four cylinders only varies by 2 psi. didn't increase either with the wet test.

bad news is stem seals must be fooked, so going to have to change them. fortunately garage has the air thingy so I don't have to take the head off!

must have been poor quality seals to start with, so going for VW ones this time.

a 16v box will only do 62mph in 2nd gear on 15's unless you raised the limiter to +8k rpm!

where the stem seals not replaced when you got the head job done?

i know what your saying about tootling about - its a head wrecker trying to be sensible!!

maybe exagerating a bit then  :grin: :grin:

but it very rapid at the top end, it even tried a little wheel spin - it was as if I'd just had a shot of nitrous!


Just had a custom power rohr made to - we'll see what thats like in the morning!!
