piper phase 2 cam!
Turbo Mini Forums

well after my gearbox disaster i decided to fit a clubman SC set & drops which iam well pleased with even though a little earsplitting at times!

also a diffrent cam to the motor a piper phase 2 ABRT002
timing duration on the data sheet is 264 inlet 292 exaust???
on the avonbar website its 264 280???

full lift at 110 ATDC on number one inlet ( this cam was timed in correctley with DTI etc and checked a number of times!

the power band is supposed to be 1200 rpm to 6500rpm

see below on the avonbar website
http://www.speedgenie.co.uk/avonbar/camshafts1.html

right, this cam drives like a bag of S***E!

it wont pull right untill 3000rpm the it comes in with a bang around 3500 to around 6500+

i think this cam is WELL over the top for the road

OR have i messed up ?

or is this cam like this ?

running T 3 intercooled, 8.4:1 cr straight through exaust.

It is interesting what folks class as 'acceptable' for road use...
I suspect I'm more like you, being very critical...

But why didn't you question the timing on the spec sheet / website - or did you only realise this after investigation?

dave it came in the box with the data sheet i saw the discrepancy but i fitted it and thought i would give a go!

its not my sort of cam maybe ok for an
ALL OUT!
race motor or am i so used to my diesel...lol

i asked for a phase two they may have given me the next generation phase 2? with the same part number.

will investigate further thanx

mines a similar setup to yours ben, 8:1 cr, T3, intercooled, straight through exhaust, clubman box etc.

I time mine in at 108 degree's as thats what the website said and it's fine. drives sweet as anything on the roads below 3k, fair enough it does take off after 3500 up to 6500 mind, but there's nowt wrong with how it pulls below 3k. As dave says you might just be too critical :)

I thought the phase to was very tractable and a great road cam, you want to try 7.5-1 compression and a cam thats almost 300 degrees !! lol.
Anyway like you i had the data sheet that differed from the figures on the Avonbar website. I timed mine in at 108 degrees and it pulled well with a smooth idle. I wonder whether advancing it from you 110degree setting a couple of deg would help pull the bottom end up a little ? I always advance it a couple anyway if using a chain, to allow for stretch. Again what you consider driveable may differ from my opinion ?

somet else to consider - I always check and compare lift on all the inlets. Helps show up any mistakes (which can happen) and the accuracy of the cam...

will check things out further

this does not seem right !
i suspect when i pulled up tonight that

that the symptoms of i head gasket blown between 2&3 pot.. its that bad.
which i may have caused that night i blew the box will check the C/R ratio tomorow and i will

investigate further

it idles worse that a super sprint cam!

WWW.TURBO-MINI.COM

check your co reading it may be just weak at the bottom, mine ran like that until i got her tuned, she was reading about 1% at tick over and about 6% flat out intially so dont be to hasty.

always looking for them bigger bunches of bannanas

ben you want a hand? am about today?

would be nice tom pm sent buddy

UPDATE: on the cam well i have to admit i fooked up!

it was 180 deg out after all those years on the spanners etc

any way nothing hurt only my pride. and a bit of putting right

timed it in at 108 spot on, it now starts at just a click of the key and idles like a pussy cat simlar to the 731 lumpiness on a 1275

havent test run it yet but iam sure it will pull its heart out
will keep you all posted

thanks for the advice all.................... & a special THANK YOU
to TOM FENTON for coming through at a drop of a hat & willing to get fired in.

i havent met anyone so helpfull & willing to help me having known tom for only a short while, top guy.

He is bloody good at cleaning cars and replacing throttle cables to....

Top job!

Jeez - I always wondered if an engine would run with a cam 180 degrees out. Thanks for clearing that up. LOL!

Next time, check all the inlet lobes (and exhausts if you can be bothered). Chances are, you'd have realised your mistake if you had (and allows you to check the cam over).

So are you running 1.5 rockers?

Ben, pleased you got it all sorted!! It sounds like we both had an eventful day with engines on Wednesday!! Old saying, he who never fucks up never does anything!

Happy to help wherever I can, looking forward to a blast when you have fully run it in etc!

Yes, top man.

Came and gave me a hand monday night and boy did I fuck up :$

dave ditched the titan 1.5s

& fitted minispares 1.3 roller rockers, none needle type

yes 180 deg out it pulled its heart out on two! pots

equal my sons pug 19.gti even on 2!!!!

Can a camshaft be timed 180 degrees wrong? I don't understand that.

I don't think so...

Explain!

Well, my camshaft is 180 degrees out every other time

oh - I was also suggesting Tom should spill the beans about Neil.

What you do, put your roof beams in upside down or somet?

Tom wont let on, but I feel I've recovered enough to submit myself to public humiliation.

I crashed the mini trike into the garage, and by into the garage I mean in through the open door and into the front of my wifes sportpack mini. Tools, tea, biscuits, Toms laptop - all went flying all over the place.

The damage to the trike was mainly to the wheel arches, as I manged to place the front of the trke down the side of the car.

The car took the brunt of the impact from the side of the trike. I think I'm looking at new front panel, wing, front and rear bumpers, maybe a bootlid (the car was in the corner near a wall), and I might need a new radiator for the kitchen as that got a bit squashed as well. Toms laptop amazingly still works, but it is very scuffed up which I'm looking into sorting out.

No-one was hurt (Tom's quick of the mark when he needs to be!) I've got some big bruises on my legs where I hit the tanks on the trike.

I was very lucky.....

oops!
