|
|
Hi, I want to change the camshaft of my 2.1 engine. I want a camshaft that provides more power and torque. This engine has hydraulic lifters, you know.
What camshatf should I put on it? I want to use it like daily, but with a bit more power.
Greetings from Spain |

Hola
To my knowledge no aftermarket hydraulic cam has that behaviure. You need to swop to mechanical. Then there are some grinds that will improve the overall performance.
- the CB 2280 has been used with hydraulic lifters with remarkable result apparently. But those engines were MW (Lower compression)
- Is the DJ cam worn ? If not I would keep it. |

Yes that is correct. But at least the Schleicher does NOT deliver better torque. It does make the engine rev higher and adds some power up in the 4500 - 5800 rpm range.
I do not know the Nowak cams by hand. But from what I have seen in other people´s engines the largest advantage with them over other grinds is the fact that they need less valve spring tension, sorta in the direction of Raptor cams.

I'm running a CB 2252 in one wbx. First with 1.25's, now with stock 1.1.

Rocky Jennings has a cam kit that I'm sure you would be satisfied with. |

CB has 4 different performance hydraulic grinds available. Webcam has 2 or 3 performance hydraulic grinds available. Engle has at least 3 performance hydraulic grinds available.
I have used them all with great success in my engines over the last 20+ years. It just depends on what kind of carburation you are using. _________________ Please "LIKE" us on facebook to see what we are working on.

Careful, the US engines MV, have low compression, 8.5:1, make 85 HP, catalytic converter, etc...
The Euro 2.1 wbx (DJ) has 10.5:1, 112hp, no cat.
Wrong cam could really kill it!
Do you plan on keeping the fuel injection? |

Actually 9-1. But apart from that |

The DJ engine, from 86 model year onwards, has 10.5:1 c/r, with a specific cam with intake closing at 48° ATDC.
I may have it wrong with the MV engine. Have to check the Bentley. Here in switzerland, we only got SR engines, high comp and cat, but only 87 HP.
But I stand by my post: the DJ has hi comp and a special cam, lots of room for a screw- up... |

OK, I can't find a reliable source for the US wasser c/r. I seemed to remember 8.5 or 8.6 :1 for the MV, but I may be mistaken.. when you say 9:1, Alstrup, is that for the MV?
I still say the DJ is a special case... |

I agreed with you. Dont get all wound up
Yes the MV & SS engines were 9-1
DJ 10,5 -1
DF, DG, and GW engines had 8,6-1

Sorry, your wording caused me to think you were calling bullshit on my post, which I don't mind per se, but I didn't want it to be the cause of some poor dude's engine exploding somewhere in the Pyrenees...
Here's what I have on the DJ's cam:
238° intake duration
230° exhaust duration
installed intake centerline: 109°
installed exhaust centerline: 115°
Lobe Separation Angle: 112°
overlap: 10°
IO: 10° BTDC
IC: 48° ABDC
EO: 50° BBDC
EC: 0° TDC
These events are all timed at 1mm, rather than the US 0.05" standard, but still give some idea of what could work. What's a good intake lobe for type 1 solid tappet 243° duration or so? You probably don't want to overdo it with lift, as this thing has valve-notches from the factory to provide clearance.
Choose a slightly smaller lobe for exhaust (230°?), and ask Webcam to grind it on 112 lobe separation, install it at 109° intake.
That said, you might increase torque, but probably not where you want it (higher up). What you really want to do is bore and/or stroke it.
Are you still using the stock Fuel Injection? |

Yes. The high lobe centre is one of the reasons that it lives with so much CR with so relatively little duration (along with a bunch of other factors of course)
As I menthioned earlier, I am not aware of any hydraulic cams that will do as Alberto wish for. But a Web 163 on 108 LC advanced 2 degrees would work very well. And with the high CR it would pull 210 Nm easy. The E prom needs to be modified and the jets need to be replaced with one number larger. That can be found in most auto scrap yards from another vehicle. I had a customer car on the rolls some years back like this, only he used a W110 cam. I remember it pulled just around 140 hp, but I do not remember the torque. The Web is quieter running and pulls better torque than the W110.
That would be my choice.

Hi again. Now I'm looking if I can put a Cb perf fuel inection (with a torque cam)
What do you think? it wil be work good? Can I keep the stock A/C System? |
