the one goodwinn sells suposedly gains like 5hp or something.
but 300+ is pretty steep for anyone that doesn't have a racecar like sav and a few others.

If Skunk2 sells it, it's more than likely made somewhere in Asia already.

After seeing how Skunk2 acts in the Honda community, I am not surprised they're trying to find some new customers. Doing ---- like this kind of killed their reputation in the Honda world:

thats awesome

It ended up in a lawsuit against a cam manufacturer/former owner of k20a.org (Nikos). I would post more details but based on how sue happy Skunk2 has been, I'd rather not get some detail wrong and get named in a case. This thread has all the details of the law suit: Skunk2 v. K20A.org - Honda-Tech

Put my Skunk 2 throttle body on tonight and it whistles LOUDLY at %10-%20 or so throttle opening, is anybody else getting that???

I'm wondering if it's just not matching up well with my DDM Stage 2 intake, the inner diameter of the intake pipe is 60mm so the air is going from 60 to 64 (throttle body) and then back down again at the lip of the intake manifold where it meets the throttle body.

I was also thinking it may be the really weird idle air intake setup, there's that weird adapter plate with the offset holes before the IAC itself that's creeping me out.

Any ideas???

whistles = leaks.

I honestly thought it was just ours or how I did the intake porting until last week at nationals.

It is not an air leak.

I am going to make a call today and ask the question.

looks likes others are hearing the same thing with it... n/m.

I've heard TBs whistle when they had a bad seal at the gaskets between the IACV and MAP sensors.

It's the idle valve. Nothing to be concerned about.

They also whistle when there's sharp corners at a specific angle (usually an accident while dremmeling).

Teeheehee!

I hadn't seen the honda-drama in this thread earlier. Skunk2 owns Kraftwerks who sold me my Rotrex. Now I'm less surprised at the lack of support.

Sav: you running one of these?

Spent a chunk of my day on the phone with Brian from Skunk 2 and in the end his tech guys said that there's no way around the whistling, it's the resonance from the hole that goes down into the idle valve like Savington said. Sort of like blowing 90 degrees across the open top of a glass beer bottle.

Piss poor design, then.

Here's the sound, for the record...

I took it off and boxed it up today, hopefully I can find someone with a turbo car and $300 burning a hole in their pocket at Miatas in Boone :)

Not to hijack, but out of curiousity, if FM can develop a small adapter to use a 1.6TB on a 1.8, why can't someone just make the same adapter to use a common Ford/Chevy TB? Seems much more cost effective....

Obviously it's a need basis type thing. More people need the 1.6 > 1.8 adapters than the alternative. I highly doubt they would want to manufacture a plate that will be purchased by maybe 4-5 people.

I was under the impression that the restriction is directly behind the throttle body in the throat of the manifold? Wouldn't that give you similar gains?

Personally i think making a pipe that allows you to get rid of that ugly 2" bottleneck at the intake manifold is better.
