Cammed 1.1?? - Saxperience

SNewham · 20th October 2007, 15:57

right I have the oppurtunity to get some cams on the cheap from a mate who is splitting his car. I'm not sure what kind they are but they for 8V VTR.

Now, I have a VTR 4-2-1 manifold already on the 1.1, the exhaust port spacing is identical, the block looks identical. Will the cams fit the 1.1? I have a feeling that I will.

Don't start spouting shit about not getting gains on a 1.1. It was just rolling roaded at 75.8 BHP which is 15.8 BHP above standard.

Obviously I'd get it remapped at same time, how much do you think I would gain?

cheers,
scott

Thought you was dropping a vts lump in it

S34MER · 20th October 2007, 16:06

what cam is it Scott?

yeh but parents are giving me shit about it. They wont "entertain" it apparently. I'll put one in when I move to my flat next year but I might as well do stuff to the 1.1 engine until then. I'm getting these cheap so only expense will be the remap.

I'm not sure, I think he mentioned 285.. don't know what make though

S34MER · 20th October 2007, 16:12

I assume he's giving you the pulley aswell?

pass, I don't know what that is but I can ask him I suppose. In theory it should fit a 1.1 though?

Barry123 · 20th October 2007, 16:15

compression ratio is different innit?
i dont *think* it will fit.

15hp above standard?

what magic rolling road was that?

Wasn't magic, I now have:

supersprint 4-2-1 manifold,
supersprint race centre section
sportex backbox
Raceland enclosed induction scoop
Fluffy dice

i honestly couldn't say mate, you'd have to try it and see, i've know nothing about the 1100cc spec.

The cam pulley is definately needed mate. the piper 285 is not a majorly wild cam iirc, but its capable of producing some pretty decent figures with a good re-map, on the VTR anyway. I couldn't even hazard a guess as to what sort of figures your looking at if you bang them in a 1.1

I like they way your being different though, camming a 1.1, not sure its ever been done before!

I’m not trying to nock you down or anything… but 15.8bhp up from standard is a lot without cams… that’s like a 26% hike in power… the equivalent of over 150bhp on a VTS without cams, and that’s got 16 valves

Don’t believe everything the rolling road men tell you as they can’t actually give you an exact figure from a rolling road.

If you’re getting them for cheap and they will fit… you might as well give them a try… I’m guessing you won’t get much more that 15.8bhp from standard with them fitted and remapped… it should sound nicer though

sound nicer!?

why will cams make it sound any different!?

Sophia_Bush · 20th October 2007, 16:28

physically will fit mate but depends if it came from a silvertop engine aswell?

75bhp is poss, gabbastards old 1.1 made that.

change the inlet to a VTR should see a little more with that on. Bah I think I will build another lump but with tbs on

Joesnow · 20th October 2007, 16:57

imo the only noticeable difference will be a slightly changed engine note!...I doubt you will be able to tell the difference with a few extra bhp. It will rev slightly higher and might have a bit of a lumpy idle… and just might sound a bit different through the rev range…

What did gabbastard do for 75bhp? I’m guessing that was a magical rolling road too! And tbh that isn’t exactly an impressive figure

smaller engines still have the ability to have an increased engine output with a select few mods. Look at 1.2 turbos etc. They push out stupidly high power for their engine size.

Even some guy on here did a 1.1 turbo and he got really good outputs.

he has that in a Quicksilver shell i believe,
says its far quicker than a VTR

thats true but you've got to look at the percentage improvments here.

Im not saying i dont believe you...
I just dont believe its pushing out 75hp.

SNewham · 20th October 2007, 17:59

Well anyway, I don't want peoples opinions just help on whether it will fit. The conclusion so far is that it will physically fit but whether it would idle properly after remap is another question

stiffler69 · 20th October 2007, 18:27

I have a vtr cam sat on my driveway for about a year now rusting the initial size and things might good for you try out

bullit · 20th October 2007, 19:06

without a map theres not a massive point. want pulley aswell. you really would be best just getting a vts engine. your car would be rapid then.

NOSHERVTR · 20th October 2007, 19:25

Yeh ok the smaller engines with a few "SELECT" mods may push up the performance a lil. I know you saying about the cars like the 1.4 gt turbo fiat and the other small engined cars with turbos toping the vtr/s but thats because they where built and designed like that. Think of the pressure your lil 1.1i engine will be under if you start messing with its main components like cams and ecu ect its more likely your pride and joy ( and it does look good by the way) will go bang under the strain so personally i wouldnt go der bud. think if you if could be dunno y didnt they design it like that in the first place, there is always a reason for not doing suming.
