If you had the option to make/design your own cam pattern which would you choose? More duration or more lift? Taking in consideration valve to valve and stock rocker arms. I'm not asking for your secret specs just asking what would your opinion be on it.

 

I wouldn't design custom cams myself. Different combinations work for different setups. Either have an experienced builder design your custom cams, or just buy a set of skunk2 pro series cams. Between the pro1s, pro2s, and pro3s they have about any setup covered.

 

Yeah I understand that but no ones making 300 whp with cams from any of these companies. Im sure the big dogs arent willing to tell how they did it but any insight on what people think is better would kind of guide me in a direction of choosing a good cam.

 

Like mgags said it depends on the set-up.

If you need custom work contact rocket at his site or skunk2, crower, or bc.

 

You need to run a motor on some cams and then tell the cam grinder what you ran cam wise and what kind of power band you got. Then you can go from there.

hope you find what your looking for im going to do the same thing in like 2-3 month everyone goes with skunk,jun ect..... and if you do a custom head you set-up your block a certain way then it makes no sense to use the same cam as some one with just a type-r piston in there ls block. for tryin to set-up your game

 

Ty,
You know who to call.

Yes sir I'll be pinging you for information on this for sure. Once you guys get the rocker arm issue settled please let me know so I can start saving, and we can come up with some different than what everyone else is runnng.

Sorry Bisi, I forgot to include you in that list. I know you are preeminently qualified.

307whp down in PR on RM Super cams...

 

OFF:
309whp B series?! LOL
Must be a "bit" optimistic dyno result!
I simply do not beleive that.

ON:
I really tend to beleive more than 12mm lift on B does not make sence , but in this case why eg. Sunk2 making cams with ~13mm of lift?

No problem. I know my company is still small...for now!

It is very possible to make even 320 whp on a B, with the right components, technology and know how...BTW, cams will paly a huge role in that power production!

 

Bisi, I know U are an expert, but I try to discuss it a bit more.

Lets look at my setup as an example.
Main components:
-86.5x89 ~13.2:1cr LSVTEC Sleeved block
-Forged rods
-Endyn pistons
-Custom SMSP B19 header
-Rocket M25x cams
-IB ported head
-IB ported ITR IM
-68mm TB
It is dyno tuned (100octane) and making 230whp at 8500.

Where the hell I am loosing 90whp?
OK, I am loosing 10-15 due to the IM, maybe an other 5-10 with the current AEM CAI...
OK, it is possible to go with a 95mm crank (in a taller block probably) and spin higher...

320whp is ridiculous TO ME, dyno numbers in the US seems unrealistic to me quite often.

I am really looking forward to some piece of advice, since I am doing sg. obviously wrong!

EDIT: This post is off topic, sorry, I do not want to start any kind of flame. Any advise to me is appreciated via PM.

Search under TBone and you'll find what you are looking for.

He's was chasing that holy grail about a yr ago.

Your post is fine the whole point is to get others views and opinions on cams. Knowledge leads to power KOCZEKA so please do question and throw your views out there.

Can you give us a little information about your setup?..
Its very hard to determine what cam specs will work without knowing what components are involved..

The best ways is Master of the Universe said:

Bisimoto told me the same thing too..

It makes sense to me as you have to have a basis from where to you want to improve...

Give Bisi a call...

 

Koczeka, what fuel do you run on?

 

100+mm crank, 17+cr on methonal, 86+mm B motor built for drag race purposes, Jenvey ITB's get you the 300hp promise land.

 

Good point! Could be my words...

Would U be so kind and answer my question to Aquafina? I really want to know!
"I really tend to beleive more than 12mm lift on B does not make sence , but in this case why eg. Sunk2 making cams with ~13mm of lift?"

yeah and the car ran 9 secs allmotor... yeah BS DYNO I TELL YOU.. hehehe i was there and the dyno he used was a well known "normal" reading dyno

 

If there is one thing I have seen over and over again in N/A performance, it is this:
Power is in the head!

Compliment the porting with a well designed camshaft, induction and exhaust, and the engine will perform wonders on a variety of displacement bottom ends...of course, the short block has to be built with the end in mind.

When all is said and done, precise tuning is extremely key as well.

 

true... work/build it as a system...

not like.. build a block.. lol and use the cam everyone uses without knowing why it works..

The original Supercam profile was so big that to fit it on the cores we have we needed to lower the peak lift otherwise the profile would not fit on the core and we would be "grinding air" on the ramps of the cam, LOL.

Lift depends on valve size. Bigger valves need more lift so K and F20C motors will benefit from lift in the range of 12.5m to 13mm. BVTEC you can easily have a awesome cam with 11.5 to 12mm lift.

You need to consider the cam as part of a whole valve actuation system and at 13+mm lift you are working the valve springs too hard on a BVTEC motor. K and F20C motors have longer springs which springs the spring load over more spring material and you have less stess per unit length of the spring wire and hence more reliability. Anything over 12.5mm on BVTEC is very hard on the valve springs.

 

U know my setup (what is IM and intake limited I think), you know how it performed with S2S3s and M25x.
What direction U would be heading when designing a custom cam for me?
