vtr with ph3 cam?

11th January 2009, 01:45

if i was to put a ph3 cam in my 2001 vtr and remap it what sort of BHP would i be lukin at, as ive got a 3" ashley back box, supersprint race centre, i have a 4-2-1 decat mani cumin and a raceland induction kit

also whats the fuel consumption guna b like with a ph3 cam in? and within what rev ranges do u get the most power out of the ph3

thanks

unfortunately you'd need throttlebodies or a rallye inlet manifold in order to run the PH3s, you'll also struggle to pass emmisions. The power is increase mid to top of the range. 3000-7000 rpm

You seriously be better off with the PH1.. power band is 1500-5000rpm which is much more useful. The increases in power are in the low and midrange. You'll even be able to idle lol

i didnt know that.. and i've just bought newmans ph3.. grrr so does that mean i need rallye inlet then?

ph1 will give you slight increase in power.

Dave newman recons on a vts running standard map it will see 10bhp so probably wont be near that in a VTR.

However it will pull better.

Manc had one fitted to his.

so do i need a new inlet then to for the ph3 newman cam of a 2003 vtr?

it won't boost peak power massively but it does give sizable increases lower down in the rev range.

The PH3 cam in a VTR has been done before with the standard inlet manifold, you'll get better result with a Rallye inlet manifold or a set of throttlebodies thou, but you will get some results with a standard inlet manifold, bare in mind you will need a adjustable pulley as the standard one on a VTR is not adjustable & a remap to get the fueling right.

The PH1 in my VTR didnt really give me the results I was expecting (421, induction, decat, cat back & dastek remap), I made 119bhp/118ftlb, was expecting more and frankly speaking was a very expensive excercise which was'nt reflected in results

, IMO if I had to do it again I would of gone for the PH3 & sacrific the idle a little.

how bad is the idle? is it stupidly shit at traffic lights etc?

11th January 2009, 11:39

iirc he does a ph2 for the VTR?

not according to the latest catalogue I picked up from David at autosportshow..

does them for the 106's but not saxos

just read thats for a 1.2 or 1.6 rallye.

depends what you were setting out to achieve. If you want a race spec cam and power delivery then the PH1 is not the one to go for.

If you want something that will give you a performance increase but still retain idle, a very usuable rev range and minimal mods to get working then they are perfect.

119bhp is quite respectable a result

that'll be because their induction is better and can utilise a wilder cam.

Fit that induction to the VTR and the PH2s are certainly an option

never simple is it

11th January 2009, 11:51

119bhp is really good imo.

pm'd him yesterday regarding ph2's so will see what he says when he replies.

Yea it is respectable but I was hoping for a little more (130bhp atw ish), but it is a daily driver and the idle even now with all the mods off apart from the cam is really good and you wouldnt know it had ever been cammed, this thankfully leaves the car with some re-sale value which was one of my requirement when I was speccing stuff up, suppose it all comes down to what you want. Here the RR graphs & vid of how mine turned out.

Cant comment on the idle of the PH3 on a VTR, certainly on a VTS is intresting to say the least

just read your progress thread about your PH1 cam problems mate.
i emailed david newman about the PH1 and he said you dont need uprated valve springs you just put the cam in and away you go... is that true??

Depends on whether you have a earlier or later VTR, the earlier VTR's did come with stronger valve springs but the later ones didnt?

11th January 2009, 14:51

is there any other option i can go for then apart from the newmans cams, what other options from other manafacturers are they, i.e catcams etc... do they do a similar ph2/ph3 kinda cam?

ah i see i have the later model..so does this mean in order for me to get a PH1 i will need stronger valve springs??

I'm pretty sure Kent Cams do a PT40 which is nigh on the spec of a PH1. I'm really tempted by a PH1 - if I keep the car long enough for it to need a cambelt change, it'd be rude not to drop one in tbh.

Manc: Where does the power delivery differ with the PH1? Do you get more low down shove or does it need winding up to free the power? The reason I ask is I've heard that camming a VTR makes little difference until you reach 80+ mph.

is that before a remap then?
and what exhaust system you got on it?
without the remap do you still feel gains?

I wouldn't mind an answer to this question please!

Ooops missed this post some how, here the reply.

That idles was before the re-map yes.

Raceland 421,Mongoose de-cat, middle & backbox (just another Magnex really)

Yes I did, that was down to the cams being timed in, bogg down 2/3k, however 4.5k upwards was crazy

So this talk about having to have bodies to run the PH3's is bull then? As yours runs even without a remap?

whoever told you that was sniffing somthing, tb's are NOT required for PH3's, PH3's only require the fueling sorting out by means of a remap. A TB'd car will benefit from cam's like PH3's thou as its dragging in more air & as a result more fuel

, hope that makes sence.

Quote:

Some are worse than others when it comes to running PH3's without a remap, When cold mine was a right pain and didnt like idling, warmed up was better, still wouldnt fancy driving around without a remap thou

ManC

7th March 2009, 21:42

Kam Racing says that you need TB's.
Still your obvioulsy living proof that you dont so alls good!

If all you need is a remap, thats good enough for me!

7th March 2009, 22:22

I think maybe Kam is saying to get the BEST result from the PH3 you need TB's, but that make it very expensive upgrade, stick with PH3 + remap then see how much cash you have left over then MAYBE go TB's

ManC

7th March 2009, 22:32

i've got cusomers running Ph3's in vts without map's but to get the best from them they need a decent map.
