I have a set of blox type B's that i want to put in my B18c5. I have read on here many times that these cams are supposedly identical to that of the skunk stage 2's. Blox did not provide the degreeing specs for these cams when purchased neither does the site provide you with the information either. To those who have had experience with these cams or even some engine building gurus, is it safe to use the specs that skunk provided on their website for the stage 2's. " http://www.skunk2.com/installation/305-05-0145.pdf ". If not can anyone guide me along the right lines here because i kno how critical cam timing can be in an engine build. Thanks for any feedback.

 

This is the very reason why people should buy Skunk vs Blox. Service/support after the sale justifies the extra cost, not to mention warranty issues.

 

I wish i knew that from the onset, then i would have gone with skunk. The only thing that blox gives.. is a reccomendation for cam gear settings, which i really think is useless because every engine isn't the same and those settings will vary in different motors. I have seen some people on the forum running blox b's in their b18c1's making fair numbers but i can't really find any of their threads... Any reccomendations on how to come about dealing with this situation? is there a different way to degree cams besides the way that is provided with the skunk cams?

 

Any other opinions anyone?

Thanks man. this will come in pretty handy when installing my cams. I was just reading the "valve seal" thread for natural aspirations and i'll be sure to check my head properly before installing these. Can't afford to spoil my motor right about now. Is there anything else i should check when installing these? Valve guides? Is it also safe to use the standard locks? Also i can hear this famous tick coming from my head.. would a bad lost motion assembly pre-maturely wear cam lobes or decrease performance? I think i read that it will give you inconsistent valve lash settings or something to that effect?

 

replace your old lma with the new spring type ones part #14820-PCB-305

 

if u still need the info for the type b settings and such, check inlinefour.com

 

Bump... Inline four has the same info i received with the cams. That is simply a spec sheet. It has no information for instance on what degree should the crankshaft be when intake/exhaust cam is at peak lift,opening or closing like skunk 2 and other brands provides... The spec sheet they provided has recommended valve lash settings, cam gear settings and fuel pressure setting. Which should be different with every motor as far as i'm concernced. I don't want to put in these cams and they decrease performance because of lack of information. Thanks in advanced.

 

Doesn't Blox have a rep. on H-T??? Hopefully they do and could give you answers to your questions.... If anyone has their H-T name, that would be great to pass it on...

 

You dont need to degree blox b's. they are a fairly mild cam...

 

Are these cams really more agressive than stock CTR cams...? cause i don't think its worth changing now i come to think of it. Blox also provides their specs in inches and not mm. In doing some more research now it seems as if blox now has stage I, II, III camshafts and the specs are provided in mm just as skunk while all other specs are advertised in inches. I may end up selling these cams for a real set and not some knock off...

 

I ran some blox b's in my h22 before, Didnt have any problems. I know plenty of people that ran blox b's in their b series motors as well. I say, if it is the same quality product and same specs, then use it. but that's me...

If you are looking for something bigger such as the Pro Series stuff, then Skunk is the only way to go. The pro series cams have to be degreed and you can find plenty of info on those cams...

 

I don't necessarily want such a radical cam.. but look at it with the duration being 266 @0.050 in while most other cam manufacturers measure their duration at 1mm. The duration for this cam at 1mm would be less than 266. 0.050 in * 25.4 = 1.27mm. Not so? i don't dispute this cam workin well.. i probably still would try it.. but i would really like to kno why is it they wouldn't provide the specs at 1mm. Probably some marketing scheme. Thanks for the info and i will try it out none the less. I think the lift is what really makes this cam a bit better than a stock or stage 1 cam.

 

Im in the process of reading these cams with a degree cam, to find the best valve lash adjustment....

I dont have the numbers here, but tomorrow i will be able to tell you this cam specs..


BTW, i found that this cams are very precisely machined, comparing the primary lobes.

 

Fail.

Most Japanese companies spec cams at 1mm lift. Most American companies spec them at .050" lift. Check out any domestic cam. Japanese use the metric system, we don't - when did the metric system become a 'marketing scheme'?

 

Is skunk2 considered a japanese company? What about Crower or Rocket motorsports? If i'm not mistaken all these cam specs can be found with the duration measured at 1mm and aren't these American Companies?

 

You are mistaken. Again. They are American companies and list their cam specs at .050"; just like almost every other American cam company. Some also list the specs at 1mm to make comparisons to cams from countries that use the metric system easier.

Skunk2 specs - http://www.skunk2.com/mm5/merchant.m...de=305-05-5140 (notice they are listed at .050")

Crower specs - http://www.crower.com/cat/import/hon...s/b_vtec.shtml (notice they are listed at .050")

Again, using the measurement system that is standard for your country is not "a marketing scheme." Its common sense.

Comp, Isky, Edelbrock, Lunati and the rest of the American companies do the same. BTW, ten seconds on Google would have given you the correct information.

 

RM measures duration at 0 lift.

 

I was gettin most of my information from here:

http://www.ek9.org/forum/resource-ar...s-engines.html

Nearly all the brands here listed are measured their duration @ 1mm of lift. Also on skunk's website : http://www.skunk2.com/engine-2.php?code=CSTB if you go to the install spec sheet it is also at 1mm of lift.

My problem is that i even tried e-mailing blox to get info and to recommend a representative or something on H-T and i still haven't even got a reply.

 

I got a set of HSLs in trade and have the same problem. The fundamental issue is that they copy other people's products so they often have no idea what the specs are or why they were designed a particular way. They don't even know the centerlines for the HSLs.

 

Exactly.. I'm not disputing if their products work well tho.. But a bit more customer service would be well appreciated. But i guess they can't help if they don't even kno their own product. Neither am i bashing other cam manufacturers who provide their specs @ 0.050" But in the link i posted earlier to the forum in ek9.org if they advertised their specs 0.050 on their website they at least provided the necessary information to post in the forum @ 1mm(for e.g Crower). Everyone besides blox provided their specs to post in the forum for technical purposes.

 

 

I only had time to measure 3 cylinders today.

Sorry, it is in portuguese:

intake low cams:







exhaust low cams:




now do your math.

compare this to SK2 S2........

 

BTW, timing means time point (0.010mm I took the other measurements form that point)


AA means Intake Opening
FA means Intake Closing


AE means exhaust opening
FE means exhaust closing


THis pictures shows in order:

1st cylinder primary lobe - 2nd cylinder primary lobe - 3rd cylinder primary lobe

1st cylinder secondary lobe - 2nd cylinder secondary lobe - 3rd cylinder secondary lobe



All values in mm





AS you can see, this cams are good till the point they are in the end of closing......
