ive got a new BD16 inlet cam sitting in my room. Tempted to get the ports worked on and fit the cam to my saph along with a standard exhuast cam. Would it be ok ? how would it drive. Poweband etc

Spec is

7.35;1
T4
83s

What inlet plenum do you have and what management etc??

We done a black 3 door on gt 35 with the same bd16 inlet and std ex on a swedish inlet plenum iirc and that done 549 hp and just shy of 500 lbft ,torque from 4k to 6.5k and a nice power band up to around 7k
The cam timing will need to be spot on to achieve this and obviously mapped well..

its on an eec4 small turbo cossie inlet.

Currently on L8 but if i do go ahead with it i may change to T2

The above car is also on L8 but its a BD16+ cam

Look at the g4 link storm ecu mate,alot newer and imo a more capable ecu in terms of ease of use etc..the eec4 inlet is fine for 500 hp
The 16 will suit him better anyway and isnt alot different..

would it be worth changing the exhaust too ?

Danny @ Enhanced Performance

iTrader: (3)

If you have a 3 inch down pipe then no need but if its a shity one then yes change it..

I've seen cars do more than that where is the restriction in these manifolds at high power?? in the inlet neck or volume within the manifold?

iTrader: (15)

You will need valve cutouts for the cam as well

iTrader: (8)

Sorry, i meant exhaust cam



Ive 4.5mm cut outs

Gav Diamond

iTrader: (6)

Might be wrong but im sure you need the spring seat machining down lower as well to run this cam

boost mad

iTrader: (8)

Realy ?

I thought you had to have the seats machined down if using isky double springs, but im using Newman doubles which dont require mods

Gav Diamond

iTrader: (6)

Like i say mate not 100% but sure i have heard it mentioned before...

JamesH

iTrader: (21)

I believe it is in the elbow?

Danny @ Enhanced Performance

iTrader: (3)

With the newman springs it will be fine on the bd16 as iv said and you wont need a ex cam to make nice power and torque
Compared to say a hart inlet or similar then yes the elbow is restrictive but its mainly down to voloume hence why people space them and stuff..
As for them doing over 500 hp then i suppose with a spacer and shit loads of boost then its defiantly possible..

what would it do if a bd14 was in the exhaust. Been offered a bd 14 and a bd12 exhaust cams unused

Stu @ M Developments

iTrader: (12)

BD16 inlet and Std Exhaust is a good setup. Others will say different but I have been using it for ten years to great effect.

Danny @ Enhanced Performance

iTrader: (3)

Alot of people have told me you advise a bd 16 inlet and bd14 ex on most occasions??
Infact untill just recently iv not heard anyone say they have used a std ex with a bd16 inlet.

Out of interest how would you set the cam timing on this set up??


cheers danny

Danny @ Enhanced Performance

iTrader: (3)

It would be lazier but rev higher..so more lag, less low down torque but more power after 6k where on the road you dont really use it..


cheers danny

boost mad

iTrader: (8)

is there an exhaust cam that would increase low/mid range torque ?

J1mbo

iTrader: (1)

T2 is a great ecu

A 16 on inlet and standard exhaust is nice, should see around 500 with a nicely ported head, 14 on the exhaust will move the power up the rev band and see a touch more power wise, the STD exhaust cam IMO gets restrictive around the 500 mark

boost mad

iTrader: (8)

can you sujest an exhaust cam that wont move the powerband too much but will not restrict at the power

Danny @ Enhanced Performance

iTrader: (3)

Yes the std ex cam!!!!!
ffs man im telling you this!!!!lol
If you want il show you lots of different graphs on the dyno and then tell you the specs??

We have loads of different spec engines at circa 500 hp recorded on the rr ..


cheers danny

Danny @ Enhanced Performance

iTrader: (3)

Fuck me you agree with everything iv said apart from the t2 not being as good as the link and the ex cam running out of puff at 500 hp as iv personally seen them do 600 hp now but agree they bring the peak power down the rev range witch imo is spot on for a road car..



cheers danny

J1mbo

iTrader: (1)

So apart from the t2 and the std exhaust cam, what exactly did I agree with

One thing, the rev range bit, You reminded me need to bump one of your other threads

boost mad

iTrader: (8)

Danny,

The standard cam wont increase it will it, as its got nothing to increase it over ( apart from no cam at all lol ) :P

Im asking if there is a cam that will increase over the standard exhaust cam lol


Although graphs does soound good

Mark Shead

The BD14 is worth it for 1% of the time and the stock cam is better for 99% of the time.

Couldnt be bothered mate as in my 63 page book it says red square beam is tarmac and green beam is gravel!!!but you will still argue either way and tbf i know what iv got so dont really care..

Cor can tell you have just came back from the states lol

Stu @ M Developments

iTrader: (12)

Really? It just shows you that a little knowledge is dangerous. I wouldnt personally use a BD14 exhaust cam EVER If I had my way.

Timing depends on too many factors to answer a question like that!

Danny @ Enhanced Performance

iTrader: (3)

I could name a few right now but wont,but the bd 16,15,14 combo is what they say youve said is needed with thier spec to sort surge etc??
Only going by what some have said so could be rubbish hence not mentioning names..
We are talking the said engine spec with a bd 16 inlet cam and std ex so theres not that many factors mate...in that case where would you start your cam timing from 112/112 110/110,its not a trick question just curious to your opinion??


cheers danny

Stu @ M Developments

iTrader: (12)

Maybe it was other tuners who asked me? LOL
Anyway, sod all wrong with a BD16/BD15 combo, it works well on the right engine.

Danny, the peak lift point you are asking me for affects the engines peak power point and as such will need to be dialled to suit the max flow of the head etc which is not mentioned in this topic. If the compressor surges due to flow invariance you will simply need to bring the peak lift point down to nearer the surge point and then rely on pure pressure to make BHP as your compromise, but speccing the engine right in the first place is a better plan.

Currently Stu, the head is pretty much standard just with the casting marks removed.

When the headwork is done, it going to be done by Neil Roper but as much as i know is he is doing the inlets port bored 26.5mm

im useing bd16/std exhaust combo in my engine & was hopeing for 500bhp ish although im thinking about selling up & going std engine with stage 3

Been advised by Stu today to go for BD16 inlet and standard ex cam on my engine.

Im pretty fine on info mate about cams as iv done a few in my time but thanks...lol
Was just asking you what your starting point would be on the ops engine to see what you would say but youve answered how i thought you would!!lol

When i spoke to Stu regarding cam choices this combo was what was suggested to me.

Danny @ Enhanced Performance

iTrader: (3)

This combo works well and much better than say a 16 and a 14 for a road car and low down drivability but in comparison to my new inlet cam there was 35lb ft and 52 hp difference on the same engine..
