IPD Turbo cam vs. V cam

[Roy 940]

Hi all,

as said in the title, what can I expected about torque and power gain with the IPD Turbo cam vs. the Volvo V cam?

My complete setup is in my sig...

Thanks for the comments and reply!

Alex.

Do you already have the Turbo cam?

He already has the V cam. I think he is asking what gain will I see with IPD turbo cam over V cam? Is it worth the money as an upgrade?

Roy940: how is the V cam compared to the T cam? I have just put a V cam in mine but can't drive it yet as have loads of stuff to do first. Does it pull harder up top? How much is lost on the bottom?

Cheers

Paul

Sorry, I forget to say that:

I run now the "V" cam, and I feel it run very well past 3800 RPM, but it's sluggish below
this point...

The IPD will correct it?

[doucheNozzle]

You have an adjustable cam. Try advancing it 4 degrees.

In my car, it loose a lot of very low-end torque, a little bit at mid range, but from 3800 to 6500 RPM, it pulls very hard!

The V is a very good cam, but not enough at low end for me...

[Canuckvolvo]

As someone already asked, did you advance the V at all?

I was using the V when I swapped heads, but took it out to put the T back in when I was trying to solve some compression issues. I don't think I will put it back, with the automatic it was just too gutless in the low end for me. I didn't try advancing it, but I still think it wouldn't be enough. In a lighter car with manual transmission it would be alot better.

[professor245]

With V I didn't loose much bottom end power, but gained a lot torque in mid range, I have a lot of torque from 1k to 4,5k but it's n/a and carbed and overbore....soooo...

[Roy 940]

Yes, I've advanced it up to 2 deg, but I don't notice a gain at low-end...but I notice a loss at hi-revs...
That's why I think about the IPD cam...

[doucheNozzle]

Yea I would try the IPD then if you have it.

[JW240]

If you think the V cam is sluggish below 3800 rpm, get someone to make a custom ignition chip. Without any changes in ignition timing the IPD turbo cam wont make a world of difference and you'll bne leaving a lot of potential on the table imho. the v cam in my car works good from 1500 rpm and really wakes up at 2500+ but thats also due to the bigger turbo.

v cam vs IPD-t, my car is faster at the same boost than another 240 that I know of. But then again, not all cars are the same so it is hard to compare.

I don't have it now, but I'm ready to order one...

But nobody can answer my question? The IPD is what I search, compared to the "V"?

I've both Mike's chips ( ECU and EZK ), so it's not right about ignition?

If you didn't buy one yet I wouldn't. I think people are finding better luck with the RSI cams.

well I dont know what has been done with those chips so i cant comment on those. It can be good, but if you complain about very little torque below 3000 rpm it could be from sub-optimal ignition timing.
but ignition maps aren't a 'one size fits all' affair. With a more aggressive/hi-rpm cam for example you can use more advance down low (to get some torque back) and you need less up top where the VE has increased. Lots of other variables too.

This can be right, since when I installed my V cam I advanced the timing, searchin to catch the best optimum advance for V cam, and it was considerable more advance needed than on A cam, but bottom torque is there, until I did that car was lazy till 2k...

[Canuckvolvo]

I know 2.4 learns, but will it learn a new cam profile, or does it just make adjustments from the base maps based on knock sensor feedback (or lack thereof)? I guess those are the same thing, but how much will it advance timing if it "thinks" it can add more?

[dalek]

Roy 940, do you want to borrow my IPD cam? Just be nice to it and let us know how it goes

[stealthfti]

What altitudes do you normally drive at? 1000 ft? 2000 ft? higher than that?

....the ambient altitude that you drive at IS a very important 'factor'.

If I remember right, Mike developp his chips in his car, with an Enem V15 cam inside ( similar to the IPD cam ), so I think my loss of torque is not from the igniton...

My car was better ( at low-end ) with the "A" cam, or it's maybe because the feeling of the "V" is different...?

Thanks, you're very friendly!!!

But the problem is : I'm located far from the USA, so it'll take some time to send it and cost a lot of money...! But once again, thank you very much for the proposition!!!

For sure, but I'm driving my car always in the same area, so 454m altitude... Not so high...

Hi Roy
I tried around with ECU's and found a huge difference in low end power with the V-cam
Best of all came the 984, then 962, then 932. 977 is said to be even better and 937 the best, -- I don't have the last two, so i can't say from my own experience.
Its also that: the higher the V-cam is boosted, the more it needs to be advanced to keep low-end drive-ability.
TLAO's chips are running far too rich for my set-up, -- exhaust black and turbo red and petrol consumption sky high -- that's not my idea of performance.
I ordered a chip from Stoni, -- he has all the other ones for comparison, and will see how that works.

The EZK won't learn anything.

[Canuckvolvo]

Ah, interesting Hans, I wondered about this as well. I'm not sure what ICU I have, but I know I also have a spare, which may be a different #. I may try swapping and see if there is a difference...
