FAO BD10 haters.
Ok...so many will say that BD10s give a lower torque over BHP figure..well here i will prove you WRONG.
Say at 2BAR held i get 430BHP....BUT i spike at 2.3bar up until 6000rpm.....how come you can FEEL the extra boost lower down?...Like it feels like a hand pushes you then you can feel it drop off to the 430BHP @ peak revs for turbo.
So with this then SURELY as it is deffo feeling more power at that RPM,torque figure will have to be higher the the actual held peak figure?

Phil,
Even an idiot like you should be able to see the flaws in your arguement
- where are the back to back tests with the standard / different cams?
.
FFS Why don't you borrow a set of standard cams and see what YOU really think

Mike all i am saying is that surely if you can feel the power from the boost spike and then tail off to the held..surely it MUST have a higher torque than BHP rating?
Thus saying that my 430BHP would NOT have a lower torque figure than that unless it was 2bar held all the way to the line..with no peak
Not denying that std cams would maybe give even more torque..but less top end

If you can FEEL the low down surge of power via the spike you MUST have more torque than BHP surely!

to realise where you are going wrong you need to realise the following
1) what RPM means 1) what torque means 3) how both these arrive to form Power
also i dont understand why you're saying that becasue you get a boost hit low down that means your BD10s are better? when you openly admit that that same hit would be MORE if you used std cams

also just coz you got more peak torque thn peak bhp doesnt mean shit to anything... my dads 1.8 derv rover thing has more torque than bhp... does that make it a fast road car?

this is probably the biggest load of clap trap that you have ever "published"
So i am right then........
As said in another post mike said i would have less torque than bhp....i disagree because the boost spike with the high comp would give more torque than bhp...regardless of cams..thats the point.

just becasue youve got bost spike does not in any way shape or form mean you have more torque than bhp...
infact its an impossible comment to make. its like saying "i had eggs for breakfast so that means it's going to rain"

I just now realise that Jim phones/mails Stu like mike does harvey...ROFL
On my particular build my torque rating will be higher than bhp.....not talking about anyone elses engines!

well youre in a position to be able to tell becasue you know the parameters of the engine (and know what the map looks like)
we're not becasue we dont know what your engine does topend...
hoever youre making a sweeping statement about BD10s and also about engines producing more torque than bhp blah blah coz of bost spikes...
that's a false statement to make
i asume you have realised why by now?
rememebr, youcan increase peak bhp without affecting peak torque in any way whatsoever...
also peak figures mean feck all really... its the graphs that actually mean something

Just Dyno it so we can all see WTF you are on about.
respect for the self build/map tho
as much if not more respect for people that helped you too.
You've given all members plenty to read and think about!

Fagin...VERY different engine!
Mike...not at all even he would go near rollers!
..It must be something to do with when i first met you and someone said you was a hair dresser..put me off rollers for life

anyone care to explain how my T34 7.4:1 engine made 388bhp and 395lb/ft @ 28 psi with BD10's on engine advantages rollers then?
and yes I do have the graph if you want it scanning in!
