Someone knows because in the page of TODA RACING (http://todaracing.com/category?secti...4&cid=22&id=10), says:

Camshafts TODA Spec B:

Spec B IN 250(11.0mm) 250(11.0mm) 295(12.0mm)
Spec B EX 250(11.0mm) 250(11.0mm) 285(12.0mm

And in many forums (included this one) this information about the same cams:

In: 12.0 mm 255 @ 1mm
Ex: 12.5 mm 255 @ 1mm

or

INTAKE lift - 12 mm, duration 255 @1mm
EXHAUST lift - 12mm, duration 245 @1mm

Which are the real measures? . That went out new versions of the Spec To (A2) and the Spec C (C2), but of the Series B there are no variants.

Thank you.

 

Here is what I have saved.....but a quick call to AKH may be worth the effort.


TODA B:
adv duration-> int:295/ext:285
Pri/Sec lobe lift: 11.0mm(int&ext)
Vtec lobe lift: 12.0mm(int&ext)
Valve lash:0.2mm (cold)

intake:
pri/sec lobe:
int open BTDC:0
int close ABDC:30
cam top center:105
duration@1mm:210

vtec lobe:
int open BTDC:25
int close ABDC:50
cam top center:102.5
duration@1mm:255

exhaust:
pri/sec lobe:
ext open BBDC:30
ext close ATDC:0
cam top center:105
duration@1mm:210

vtec lobe:
ext open BBDC:45
ext close ATDC:20
cam top center:102.5
duration@1mm:245

 

Sure,
This information also I have it, the differences in the measures it is that are generated by that the measure in duration is not to @1mm at the time the results they are not the same. The real specs in comparisson

The real measures in comparison to all them of @1mm, are a bit minor.

Regards.

 

The two cams have 12mm of lift..

 

Yes, But i found different specifications about the DURATION, not the same.

This is the right info.....

 

Sure! Duration at @1mm is different.

Thx!

Hi guys!

I brought about two years ago used cams on ebay. The guy told me that they are BC4's so I tried to use camcard for BC4's and nothing actually worked. I decided to google for the cams I have. The only thing I was looking for was stamp with letter B at the end of camshaft, which I found was only used on Toda spec B cams. So a couple a days ago I tried to degree them. I used primary IN and primary EX. At first I tried 0 valve lash and intake duration @1mm was 177 degrees and 220 degrees on the exhaust. When I degreed them the cam gears were like 10 degrees advanced on exhaust and 4 degrees retard on intake. I'm running B20vtec 12.0 CR, Skunk2 valvetrain. Could those be fake cams?

 

They could also be Blox cams IIRC
