Help needed please
I have driven my 3 door today for the 1st time and I am really disappointed
It's now where near as Quick my mk1 escort cos stage 1 on t3.

It Boosts at 17psi on (1.2 bar) but really late almost 5k, so sluggish bottom end and mid range.
It's on greys
It has a BD14 inlet cam and the exhaust cam is unmaked at the end, not sure what turbo itis but have a 48 rear housing and the front housing is marked up M27??
If it helps the inlet I'd is 63mm pic below. I would like much more bottom end, any advice?

 

That turbo looks big (Like T4 sized maybe?) if so then this will be why it's laggy.

The general rule is standard exhaust cam and modified inlet (BD14 like you have)

I would say if you don't like the lag then really you should go for a smaller turbo, you won't have as much power, ultimatly, but it will be more responsive lower down.

It's essentially always a compromise between power and lag.

I think M27 relates to a 'casting' number.

What's the best way to tell what turbo it is?

 

Looks like a T34 or baby T38 to me

 

Looks like a T34 to me too?

Is your actuator ok? I had the exact same cam/turbo combo as shown and mine came on boost at around 3500rpm. Even now with a larger .63 housing and the BD14 inlet its on full boost before 4000rpm.

If you want better response put a standard inlet cam in. You car also needs more boost IMO. Mine peaks at 32 psi and falls to around 25/26psi at the limiter (Live mapped by MSD)

 

I will check the actuator tomorrow, I have a new Collins -31 on my that I can try
What cams are standard?

 

It looks like you have the potential of a 380+bhp engine but it needs setting up imo.

 

nothing wrong with your cam combination
14 inlet std exhaust is fine
lag is more likely to be a turbo issue no wastegate preload sticking penny in the hole etc etc
boost control is best with a boost control valve a correctly jetted amal valve will do and is cheap
the turbo looks like a t34 with a .48 turbine housing and should not be laggy
cam timing could also be an issue
110 exhaust 115 inlet would be better for response
my advice is take it to a specialist that can set it up and check it for det and afr and can map weber

 

i have installed my other -31 actuator with about 10mm of pre load, response feels a little better but still boosting 17psi but a little earlier.
how much pre load should i have?
when i remove the actuator the arm seems to be stuck closed and needs a tap to free it, is this normal?
can you recommend a tuner? i am just outside Birmingham.

 

Martin @ Reyland is in Birmingham mate

the waste gate arm should be free
you have more than enough preload
you need an amal valve next to increase the boost don't do it by shortening the wastegate actuator rod
martin is in Birmingham I am just north of Birmingham J 15 m6
You can call me on 07587188434 if you need any advice
Regards Tony

 

I would go for an electronic boost controler and take it to a decent tuner for a good tune.
17psi seems low for an engine running grey injectors. Check for boost hose leaks too!
Dont forget a 3door will weigh a couple of hundred kilo's more than a mk1! Dont try comparing the two!

 

Sounds like your wastegate might be jamming up. So it may not be closing properly wasting precious exhaust gasses!
Waste gate's usualy move very easily. They just flop about.

 

agreed alot more boost

take it to some where to get it all set up as it should be

 

If you are close to Tony I'd go there, live map is the best thing I've done to my car.

 

Booked in with tony on Friday

 

The old fart has a rough idea on what he's doing

Steve

 

Tony will have it running full boost in no time

 

Went see Tony at Turbo Systems yesterday, he found that my inlet manifold was leaking air, exhaust cam timing out by 8 degrees, inlet cam out by over 1 tooth and a map from a 1910 Model T ford.
I arrived at around 10:00 in the morning with a car that was shit and after have the issues corrected and live mapped i left at 10:30 at night with a car that put a smile on my face!!
I can't recommend his services enough, Tony is a real nice guy (old n grumpy ) and proper knows his stuff.
The car is now peaking at 2.1-2.2 bar and holding 2 and goes like a rocket ship. The low end power is also a lot better and not like a 1.1 fiesta popular plus any more Cheers Tony.

 

I said the old fart knows what he's doing

Steve

 

Half ten at night Fair play to you Tony.

 

it seems to be every fookin friday with these supposed special spec cars with these supposed special engines built down south
never seen one where the cam timing was any where near what it is supposed to be
not a pleasant easy job to do in situ either but it is free with every engine I build on the bench and doesn't need redoing in the car
absolute joke these supposed specialists imo I could have guessed it better with a fookin sun dial on a cloudy day
any more of these long days and the x wife will probably divorce me again roflol

 

thats the way to do it

 

That's the shortened version the full version of problems and issues would take up 2 pages

 

How the christ can someone get the timing out that far?
I wish i could get my engine mapped by Turbosystems...only 1800km to drive...

 

quite easily it would appear

 

It would be silly to suggest that joe would have set the cam timing to that!!!lol...

Or is this a special northern way of cam timing??


cheers danny

 

I never mentioned anything about joe
I just stated some facts from what I have seen over the years
The cam timing figures on this particular car were 103 ex 126 inlet
ex cam was a bd8 inlet was a bd14

 

Bloody hell!!!! thats more impressive than harveys timing(according to jimbo)Lol!!!

Was just going by the southern tuner you mentioned and the fact it was built by joe??

What did you settle with cam timing wise??more like 116 in 112 ex?? or similar..

I like to start with 112 112 when setting them up on a bd14 and go from there but with that spec for a good all round performer on std cr etc its normally about 4 degrees more on the inlet when finished..

My race engine ended up with 116 108 in the end but that had a 288.474 in and 280.416 ex ..that was the best compromise for power and torque in the end..


cheers danny

 

considering your south of watford are you sure the cam timing you settled on isn't more like half past 20 to

 

Youve lost me and answered nothing????

It must be the northern humour??lol


cheers danny

 

ps..i pm you about supra diff conversion??
