rallye inlet and cam, BHP?

14th February 2010, 14:56

alright lads ive got a VTR 99 reg with late mk1 engine, im thinking about bolting on a peugeot rallye inlet manifold with a decent aftermarket cam,a remap and stainless steel 4-2-1, the engine i got in atm is in top nick, what bhp gains am i likely to see? Thanks Lee

i reckon, depending, as you say its all tip top condition you'll see 120? probably be keeping up with VTS's, but you've gotta think all that money you could be keeping up with the VTS/GTi boys, why dont you just buy the whole lump and save a massive wedge with the reliability of a standard engine too. Obviously its up to you, i personally drive a cammed VTR and its sound but im just gonna S lump it soon

You have the 90bhp silvertop engine yeah?

Hmm

S1 inlet - varies but 5/6bhp
PH3s + remap - Possibly 20bhp
4-2-1 - 3-4bhp

So as above really, possibly 120bhp but it's difficult to say mate.

ask vtr chris iirc if thats his user name? prozzie blue silvertop 90bhp jobbie has same spec

Yer I have a similar setup to this, I have made 120bhp unmapped
but with ph3 cam and s1 inlet you could see around 115bhp unmapped poss a tad more it depends on the rollers and how well you time the cam up, that's the main thing though getting the timing right

or for a bit more power get a either rallye or xsi head and a ph2 cam, or blacktop vtr head an blacktop ph3 cam and you will see a bit more with that than you will with a silvertop ph3

Friend of mine has S2 Rallye engine with S1 inlet, PH2 newmans and breathing mods and made 121.4Bhp. That was on a fully rebuilt lump too. Expext to see anywhere from 110-117Bhp tbh at a guess.

I have the Blacktop Vtr Head, Cam and Rallye inlet, 4-1 Mani, Decat etc

and its approx 121-126 Unmapped

My rallye is 103 standard.. piper cam, pugsport , vernier pulley.. 123.8bhp.

Notice alot of people in this thread haven't had a remap, is it possible with a ph2 to run it without a remap?

Yes, should be fine without a map but of course better gains will be seen with one. Even PH3s can run without a map but it's not ideal.

+1 i get the same with my 1400 just go and put a 2 litre in,
changing engine will put your insurance but this depends on age of the person,
at least if you do the work your self you can take the credit for it or do what the sheep do buy another engine and take the credit for some else's work but if you buy another engine this could/can/will have more problems than you already have(eg dont know when oil changes were done, been thrashed from cold,stem seals could be worn, bearings and oil seals leaking)
what is wrong with modding the engine you already have?

Thats exactly my point mate, im fed up of people saying to me just buy a VTS engine, yes it would be nice but every1 seems to be going for that option, i want to stick with the 8Valve, every bit of work done to my car is done by myself..

tbh mate with the ph2 you will need a remap just as much as ph3, it will run just as lumpy if not lumpier than a ph3 depending on which one you look at
cause th ph2 is 280deg, where as silvertop ph3 is 270deg, and blackop ph3 is 280deg, and as a few peope have said with their ph3's on silvertop and s1 inlet it idled nearly as good as standard, it wasnt that lumpy, but if you look in my prog thread i have vid of how lumpy the ph2 cam is

plus you will need a rallye/xsi head too, which means changing a lot of things unless your vtr is a blacktop
so best to stick to ph3 tbh as you wont gain any less or any more and wont have to change as much either

Yer well I've got an early silvertop so a rallye inlet would fit, so you suggest without a remap, running ph3's but definatly with the inlet yer?

with the ph3 im sure it says on kams website you need the s1 rallye inlet, ive just fitted a rallye head and inlet along with raceland 4-2-1 manifold and a supersprint exhaust and im currently trying to get it running its running like a dog at the mo you have to remember the s1 rallye inlet was made for a completely different engine and its not exactly "plug and play" i can see my car being off the road for a while trying to sort this out grrr

i was naive and thought this would be easy for example the rallye fuel rail has 2 fuel lines on it my vtr only had one so i then went to fit the vtr fuel rail and it wouldn't fit in to the head so i had to take them both apart and swap the injectors over, i have to convert my engine to use ht leads instead of the coilpack it came with and if you wire this up wrong it will come up with fault codes and you engine management light will come on and wiring up the icv and tps isnt straight forward either just do plenty of research before you tackle it everyone

the inlet will fit your head yes

but you will need a remap whether you fit the ph3 cam with the s1 inlet or not mate tbh

i found fitting the s1 inlet caused my car to underfuel, where as with standard inlet it was over fueling
so you will run into all sorts of issues that can only realy be solved by getting a remap

it can be run unmapped for a bit but it could potentially cause problems, but then it may not

so do some research first aswell before jumping into the deep end and getting it all fited then run into probs, cause its not as easy as it seems just to plonk a cam in fit a rallye inlet then leave it unmapped, itsnot as easy as that unfortunatly otherwise every one would do it, your looking at a good 700quid area just for the parts tbh, you will also need to pay for rolling road to tme cam up properlywhich an cost around 100quid depending on who you go to and who charges what etc, plus then mapping is about 350 upwards
so it isnt cheap which is why alot of people just put 16vin
