I will personally call Delta cam and discuss this with them.

 

That isn't a very good test tbh. You should have dyno'ed before and after delta to be sure about the gains and where are the changes. Oil change and seafoam may just be only a placebo effect.

Why would they change MIVEC to a lower profile

Also as Ralliartize It said, the power starts to go down at 5.5k RPM on OEM cam so rev's up to 7k are worthless unless a better CAM is installed.

This LINK takes you through some aspects of cam "theory" its an interesting read...also note:

" With a shorter exhaust duration to allow the gases to escape and an earlier intake closing which stops the fuel/air mixture which is trying to enter the cylinder at higher RPM and a wide lobe center angle, the engine reaches optimal running conditions around 2000-2500 RPM but quickly runs out of breath above about 4500-5000 RPM."

Obviously that's his example but you get the idea...with no data logging most of the questions wont be answered fast

 

that's the point they grinded the wrong lobe from the start.... and if they didn't even know what lobe to grind I highly doubt they knew what they were doing past that.... I'm disappointed , depressed, and feel screwed overall.

 

I would ask for a full refund or fix since the cam is not as per the specs they advertise...Certainly not good business for anyone thinking of buying their cams

 

lol they never advertised anything this was their .....stage 1 cam that Ralliartize it got started with them

 

Did they tell the finished cam specs before buying the cam?...thats what i meant or is it some bullcrap mystery cam like the one from RRM?

 

well I have a Copy o the print out of Ralliartize it's cam that is supposed to be the same specs as mine....

 

details...

the quicker we sort this out, the quicker i can get a cam, let's move people!!

 

I have an e-version of the cam specs I can send to anyone. PM me with your email address.

 

Wow there were a lot of posts recently, I'm still trying to wrap my head around all of it. From my understanding, we found out that Delta may have messed up the cam? Sadly I can't really have my car down for another month with the mess up I had last time

On a side note, for those that have it, have you noticed that when you're not WOT you don't have the power loss. At least for me it happens. Like I can push it all the way without a loss in power. Maybe I'll do a recording just to make sure I'm not just thinking it.

 

Cranswick I have emailed you the specs. I will call Delta once we 100% certain arrive to a technically sound answer to this situation.

 

What kind of answer are you waiting for or wanting? i have already explained the problem etc.I have the delta and stock cam out and in my hands for measurements , pics, or whatever etc.

 

Lanzer I will re-read the thread and draft a platform for discussion with Delta. I will email you what I am thinking. I don't want the thread to turn into a full-scale Delta bashing medium before I have a chance to speak with them

 

Ralliartize It have you called Delta?

 

I have not called them yet. That is on my to do list for early next week.
