I've got the W4M 9.5 pulley, heat exchanger, and tune on my 6-speed manual CTS-V. The car seems to fall on its face and feels like all the timing is being pulled. Jesse thinks the stock intake tube is collapsing. Anyone have the 9.5 pulley and heat exchanger with the stock intake tube? Any issues? I've only had this on the car since last night. It was fine last night, but this morning it started to fall on its face. The car has 4,000 miles.
So confused.... First post; jessie said the stock tube is collapsing. Second post; Jessie has no idea what's happening. Anyway, did you refuel and possible get bad or low octane gas? Did you do the Stock airbox mod( if not, probably need to).
Jesse said he had no idea, but then he said the only thing would be the stock intake is collapsing. When I called him back later to order it, he said, "why didn't you get the intake with your pulley?" I had already asked him several times through email if it was needed and he would never respond.
Just to recap: So when I first tell him about the problem he has no idea unless it is the stock tube collapsing. Then on the 2nd call ~30 mins later, he acts like everyone knows that you have to have the intake with the pulley. :cookoo: I'm tired of him talking to me like I am a dumbass evertime I call.
He needs to hire someone else if he is really this busy. He claims he gets 400 emails a day, and he can't respond to them all. BUT, he answers every one I send that I am asking to purchase something.
I'm seriously contemplating taking everything off the car and just keeping it stock because of all the crap I am running into. I just want the car to run right. When it has this issue - whatever is causing it - the car is slower than a Prius.
also, I've read about people having an issue with not getting the air out of the system when adding a additional heat exchanger. That would cause the car to heat soak quick, pull timing ect,,, Just guessing
No, I just ordered the w4m intake. Now Jesse thinks it's the p valve. I'd never heard of it, so I did a search but I haven't found specific instructions on how to get it plugged yet. Still looking...
Way back when (like the end of 2008), Jesse said the stock intake tube would collapse when you were putting down over 600 RWHP or so--when the bottom was cut out of the stock airbox. You may be collapsing it due to the pulley trying to draw in more air through the restrictive stock air opening. Might be worth trying a few runs with the airbox cover removed.
Might want to consider talking to James at D3. Somebody on here a while back came up with some ingenious method of stopping this issue, and I believe that it had to do with placing some type of spring inside the stock tube.
Stock tube collapsing is a symptom, the cause is restriction on the other end. Just like sucking through a straw there is no way to make it collapse unless you obstruct the other end.
Look at Lunds 800hp race car and the stock tube is on it. The restriction is the airbox that is why everyone is modding it.
