What's the word on bypass valves..? Are they good bang for the buck..? Pros vs cons..?
I'm thinking it's time for another mod and this seems like a popular one.

I knew I was special! I ride the short bus!
You mean you don't like it..? Why not..?
I've read that it makes the car more responsive to the point where it can be jerky. Is that a common complaint?
What are my other options..? I've got a 15% pulley, a Webb intake, the JCW exhaust... I still get the bogging down when pulling away and I thought that the bypass valve might help that. Does anyone have any other suggestions..?

I'll try to explain. I started with the JCW engine kit. With the valve installed, I felt the car bogged down in 2nd gear unless I was really really really on it. The mod was probably a mistake for me, since I thought my car pulled away from standing well to begin with, and I didn't have any throttle response issues. There's another guy in PA (geowit) with an older MCS who had the same opinion as I did. Not sure what mods he has, but he got his DT BPV because his stock one failed completely. He also felt the car bogged down a little bit. Then again, out of all the people who bought one through the Mass Motoring group buy, I'm the only one to do a reverse bypass. So, YMMV.

btw, the minimania one doesn't appear to be a modified valve. Just a new stock one. DT supposedly replaces the spring and adjusts the valve to ensure it completely closes and doesn't have any leaks around the edge.

they are, I would say 99% of people love them. Definitely a good bang for the buck.
Hated mine. It's back in the box. On my '06, it gave horrible surging, abrupt throttle response, and generally made it unpleasant to drive. If anyone wants it, drop me a line.

Nope, not the only one. :D I've just been uncharacteristically quiet on my displeasure with it. Until now, that is. Muahahahahaha! :tongue:

I thought it looked like the MiniMania one said they made sure it closed completely. It was kind of unclear whether they'd changed anything though, or if it was just a new stock one to replace a tired stock one....

I agree about the surge and the abrupt throttle, but to me the gain was worth those things, I'm pretty laid back about my car though. I really enjoy the throttle response being much better. Did you sell yours yet Brian?

Gav, if you haven't done it, you may want to think about a new set of plugs, I just did mine and the car runs a lot better. 58k on the stock plugs.

Brian might be selling his soon... ;)
I did buy new plugs - the Denso Iridium ones but shortly after I put them in, MOP scared me off with stories of them blowing out and causing a lot of $$$ worth of damage, so they put a new set of stock ones in. The car is coming up on 58K miles, and I can't remember when I did the plug swap and back, but maybe I'll put the aftermarket ones back in... Doesn't the JCW use uprated NGK ones..?
What plugs would you suggest Pete?

The " Jim Willis " bypass valve just put in the '04 MCS is a big step up over stock. The stock bypass had clearance all the way around the butterfly, and spring was weak.
The new valve has got the snap back and the throttle. The surging is minimal on the 04.
I'm OK with the mod.;)

Is there anything in all the ignition mods..? New coil, bigger wires, different plugs...?
Isn't a spark, a spark? With all that fuel and air compressed in the cylinder, how big a spark do you need to set it all off..???

I just put a set of NGK irridiums in, also added a drop of loc-tite so they wouldn't loosen and blow out. I checked them this week, and they haven't loosend, still 22 ft. lbs. Honestly I'm not sure if the JCW uses different ones, I'll have to look into that.

I like hearing when folks didn't like the mods, it's a lot better to know what to expect, good and bad. Until now, I thought it was only Adam and Steve that didn't like it.

I've read a bit on the screamin demon coil and wire set up, and a few people have used it. from what they've said, it Didn't live up to the expectations set forth by the company. Unless you have a need to replace the coil or wires, to me it's probably not worth doing.

That is a nice valve, heavier spring and from what John said it was a bit cheaper than the D.T. Bypass.
