the number is the throttle size and the letters denote the style,e.g doce side draught, ida down draught, big think is to know what size ventuires are in there, e.g 32mm or 34mm etc, the general rule is smaller the venturies the more torque low down, the larger the venturies more HP hi up.

but there's alot of other factors that come in to it.

 

like the cam in the rally car, it's a about 40-80 and you can still drive it around town in 4th at 50kms and it's happy. i'd never put a cam that big into a street engine, because it wouldn't be happy until your over 5 grand.

f@$k thats huge,what size engine?

 

that cam i was talking about is a 57-83, with 280" lift.

it's too big, especially for a stock 4k :D

 

i wouldn't put anything over dcoe/dhla40s on a 5k, it's not going to flow THAT much. you'd probably want the smallest chokes you can get it them too (32mm? there are some 28s around but very rare)

 

some facts:

the restriction point on a 5k is the valve size

25/65 is the best cam for a 4k-cranked engine

it's too big, especially for a stock 4k.

 

"not a f@$king rotary... jackass"

this isn't for a stock engine!!!

f@$k you'd be lucky have the thing idle under 3000.

 

i used the kelford f18 grind in my starlet and it was magic, have also tried a f 18 grind, has more lift but wasn't happy with it.

 

i'd be interested in one of those stickers, or "it's not a f@$ken datsun asshole" sticker

 

sorry MEL :D

nick and i seem to think that my cam is around the same as his was.

 

Cam Settings

 

look to signature for what engine its in.

Just PM me any sticker requests. I have a pretty awesome turnaround time and good prices. Quite a few people have used me in the past and may be able to back this up :D

 

My car idled at 900rpm but it sounded like a rotary.

 

What are the specs for the F18 grind you were happy with?

it's in the kelford cams chart, there's a small mark beside it.

 

cam chart

 

i'll PM request for a sticker soon.

xany's cam isn't too bad, it's down on torque but being in a 5k helps cover that up compared to a 4k, it's probably still better than say my or teddy's motor because of that. and it's gonna be better than stock no matter what :D

Sounds like you want to do what I have sorta done.

 

I'm running a KE20 with a 5K. It is running a Wade 169 grind which I have lost the specs for :sad: This cam allows me to rev past 7000rpm (have seen it past 8000rpm, but that was on the factory tacho which was optimistic).

 

I'm still running the standard head but on a previous 5K port matching and a compression hike (shaved heaps but still able to run "super" back in those days) made a big difference to the torque.

 

Current 5K is fitted with a 3KB manfold and a pair of standard Corolla carbies (bigger venturies) and 4 into 1 extractors and a 2" exhaust plus a few other mods.

 

The above combination made around 3 seconds difference a our local autocross track over the standard 3K. Works out to be around 1.5s a kilometer quicker.

Also at the last Challenge of Clubs, I ran 2nd outright in a field of 65 cars, behind a mini special so I think the combination works quite well.

Gday Col, good to hear from you again!

Sorry Mel

 

I'm not sure I can forgive that!! :dance:

 

It's not the almighty Datsun's fault if they are so well known that everyone thinks that Corollas look like them!!

 

But perhaps a forum purely about Corollas is not the best place to start that discussion, I may lose. :blinks:

 

:D

sorry!! but he started it!!

G'day Rob.

Long time no see since you left "mexico".

wade 169 is a hyd cam. timing 41/70 75/36 291 degs dur .402/.403" lift at valve.

wade 169s is a mech cam. 30.5/66 72/26.5 278/276 degs dur .396/.394" lift at valve

Wade 169x 30/70 70/30 .270 lift at lobe. Can't remember the rest....

So all this cam talk... hmmm...i just want a cam that will work for me :D

I would also like to know the cam specs for a 5k that I want to pull from down low (Motorkhanas, Khanacross, and Hillclimbs) but wont die at 4500rpm for the use in Autocross???

 

thanks :S
