Drag races will be held this weekend, and I'm going to race my car.
I want to know how much of a difference would the CDV do on my time, because I was planning to keep it on but if it does affect a lot my time I might as well take it off.

What would you guys suggest?

 

take it off. the delay valve is meant to prevent damage to the diff and tranny, so your clutch pays the price in accelerated wear.

You want the clutch to hook up so you can break the tires loose. taking the valve off will make this much easier.

 

Is this on 2004+ or what?

 

yes it is, also what kind of effect would this have on 1/4 mile times and such!

i want to do it, but i dont have a dental pic and im scared of mechicanical work cuz i dont knwo shit!

 

take it off. you will jsut burn your clutch and it will smell like crap.
i took it off and the clutch/shitting action is much better.

 

It would be the difference between a "clutch slip" start and a "clutch drop" start. It has been said that to get a really good ET on this car, you have to "launch the crap out of it". I seem to recall someone doing both with an AP1. The difference was between 1/2 second to 1 second.

ps. It has also been noted that you can't "launch the crap out of it" with the delay valve in.

 

Ok for anyone that might find this info usefull, my best time this weekend with the CDV was 14.662. (stock car, 900 mts above the see level and around 97

 

I could be wrong, but don't we have a member who ran a 13.6-ish with an AP2 now and still had his valve in?
