I am thinkin about running a Set or One BD10 cam in the cossie, Which is the better setup Both Cams or just one on the Inlet ?? I have heard that you get either more torque or BHP with one or the other setup is this true ???

Cheers

Alex...

 

Yes more top end power, but at the sacrafice of what you gain at the top end, as a loss in the midrange.

 

Alex,

Dont do it!

Ask Dave Griffiths at Interpro about the saga when they fitted BD10's to my Bailey Saph engine (it was running STANDARD CAMS)........With the BD10's fitted I "lost 22 BHP and 28 ft LBS torque, verniers were fitted and dialed in correctly etc

The next day Dave fitted the STANDARD CAMS back in (no vernier required as thay had offset keys) and as if my magic all was well again: 408 BHP with 396 ft LBS on 26 PSI boost!

 

When the car is back on the road i am going to be running a T34, So i sounds like i will be better off running the Standard cams then because i am looking for a Reliable 330 - 340 BHP running less than 26 Psi Boost..

Al...

 

Ok, and maybe spend the (BD10) money on a good boost controller, like the Grredy unit that Simon (SECS) and I use....the boost controler will be of use to you whatever spec engine you've got or eventually end up with!

 

Doug you wont have dialled them in at the right setting mate,a very good set of cams to choose Alex

 

Basically I suppose it will be best to run just the one BD10 on the inlet so Mid Range torque is will be better than top end really.......


Al...

 

Actually Phil, Interpro were supplying me with the BD10's and verniers, they fitted the cams/verniers, they spent lots of time with my car on their rollers dialing the cams in, adjusting, and then re-adjusting - then they gave up and fitted my standard cams back in!

It was deffo in their interests to dial them in correctly!

 

Yes mate but do they know the right figures to dial them to???? Not being funny but i loved those cams and compliment the T4 well imo.

 

OK Phil, maybe we are at cross purposes here, I am referring to a T34B conversion (hybrid T34), standard comp ratio, light blues...........It might be that the BD10's ARE suited to a T4 application as in your case!

CUE Phil to respond with: "ahh, but the light blues are a 370 BHP injector"

 

that's strange....you buy better cams and you lost bhp and torque. is it better to change only the inlet then to bd10 or what?

 

I know that it seems that way, but it would appear to be a mis-match problem IMO.

I am sure that our cam guru Karl Norris did confirm my findings on this subject on a prevoius thread That is to say that Standard comp ratio with T34B + standard cams is a GOOD combination.

 

maybe Karl has to answer this????

 

Phil,
Did you ever use standard cams with your set up? No - so shut the fuck up, you don't know what you're talking about . Also, when when did you car ever run at it's full potential? .

BD10s move the power up the rev range and would be even MORE shit on a T4 and loose even more response. Even Karl who is a fan of the BD10s acknowledges this .

 

moving power up the rev range. Mike what do you suggest, using one bd10 on the inlet or both bd10's

best regards

 

I suggest sticking with the stand cams below 400bhp with a T3/4 .

 

Mike it is good that we both agree on this subject.........but does it not bother you that neither of us are engine builders...........and of course IMA IS an engine builder

 

Well i run one bd10 ther diference i noticed is like mike said i lost a bit of midrange that sounds right but she pulls like a train now top end

 

Is he fuck, he's an engine assembler - BIG difference .

 

I think my plan is to Get a New chip From Stu and run a T34 with standard cams......... , Take the cheaper option...

Al.....

 

Mine is standard cams, t34, and seems to work OK.

I am with Doug on the boost controller as well - soo much better with that on.

 

i have bd10s i never had a power run but felt sooo much quicker than cars with similar spec boost

No offence doug but my experience with interpro has been poor.

while dave offered some good advice he does not call the shots and i have allways found them to be money grabbing bastards.

On my fiesta they told me they couldnt do this and that due to the compression of my engine.

I just built that engine myself with parts new from ford so i took it else were and found there was no problem with my compression and was setup and released another 19bhp

i would only go there for a power run

they wont be getting any of my money again

i bought my engine with bd10s and verniers so im leaving it as is

 

How much are a set of BD10's Usually or can you have your old cam re-profiled ??

AL.....

 

CraigN, Your's is lo-comp though isn't it?

 

i was on about my fiesta

but yes my engine is different from alex's

low comp greys t34

i wasnt arguing with mike or dougs comments baout the cams as tbh i havent gota clue

just the fact im not too keen on interpro

and similar spec cars with non low comp engines and similar boost have felt a lot slower to me

 

Id agree with u craig interpro are CRAP they robbed me for 500 quid and my car was no different same power,

 

Ouch!

 

No steve the best bit later found there was a boost pipe hangin off jubly was done up on angle he said it was detting over 23 psi held and there was fuel so he said. So i was told compression of my car is wrong or my chip is tottaly wrong?and he charged me 500 to tell me that i infact had less power than when i went in.

 

nige they charged me £430 for a stage 1 chip on a fiesta

its a plugin chip and they installed a bleed valve didnt even touch my actuator
