How much boost was it holding out the top?

Haven't logged it to give an exact number. Most likely will on Thursday if the weather holds. Don't get much time to take it out.

sounds good. I had one here last week and I am curious if the taper I saw was normal or a sign it REALLY needed a 3 port.

Just curious what you guys pulled out of one? Results are few and far between on these things.

I was told it was a pre release version so I am not sure what changed afterwards. I will dig up the dyno sheet in a sec.

Stock 2.0L VIII, S2s, SD, etc. but had a megan or small O2 housing on it at this time. John is swapping to an O2 dump and then we'll retune. It also had a manual which is why I am curious what you were seeing out the top. I feel it would definitely be better with an O2 dump and I believe he is doing the external gate one so we can run boost top and bottom. It didnt want to take much timing out the top, that is low timing and not knock in the dyno sheet.

How much more power do you think this car would make with the o2 dump? I'm taking your advise as you once commented on one of my threads that my bigger o2 housing is probably a restriction on my setup. I'm going to pick up a map o2 dump.

It wouldnt surprise me to see another 40whp anyway. If I cant run the timing and it truly was because of backpressure and not just octane somehow, more than 40whp. Life is Combination.

anyone that says different is selling something.
