I second what Doward said, depends on the Ebay type you got. I have the Tial knockoff, and it has never leaked to my knowledge, and will vent during shifts as low as 1psi.
PS- Starscream- I love that Synapse BOV, looks awesome.
Like the thread says, I was wondering how you actually treat carbon fiber, and form it. Is it worked in a similar fashion to fiberglass weave, in that it is used with a epoxy or polyester resin? I was just wondering if it was that easy, as it seems that it would make more sense to work with CF...
Yup- Like he said- they might even be able to WIDEN the hole slightly, to weld in an AL bung that matches the original size, instead of top mounting it, causing it to sit higher than stock.
Dumb question, but are you sure you've got the right bolt? Is it possible you're comparing the bolt hole to a banjo bolt belonging to some other part of the motor?
Like I said, it was a dumb question.
As for your original question, I would expect you to make about 300-330HP on low boost(~10psi) with that setup, provided the engine is fresh, as stated above.
Usually rodknock is something you hear on light throttle between 2500-3500rpm, and it sounds like a faint jackhammer during hard acceleration if it's gotten bad enough. if you just put it in neutral, and rev it lightly to 3000, listen to it with the hood open, and if it sounds like a sporadic...
I've also heard of the wet tissue trick. Same idea as the grease, it's just perhaps a bit more forceful, as the tissue is more of a solid than the grease.
I count possibly four items in the description which I think are wrong...
See if you can name them. I already emailed the seller, asking for verification of some of the info in his auction...
Update-
I gave up on cleaning the exhaust valves up. I tried the above recommendation of using a wire wheel brush, as it STILL wasn't making a dent in the carbon! After finishing two valves, I said fugg it. I bought a new set of exhaust valves, and put them in today. Comparing old and new...
I think I've decided on a stage 2 in place of a stage 3 myself. I would like to eventually get just above 400hp, but it's not going to be for awhile, as I'll be having to switch turbos, manifolds and DP attatchments, so by that time, the car would be ready for another clutch change anyway...
I've got mine in right now, it makes a big difference in the droning sound of the exhaust, but haven't really noticed a major drop in power.
I'm a pretty light throttle driver these days, though. Trying to baby this engine to make it till my project motor is ready.
