I was wondering about something's
I'm running a second gen 94 spec EG6 b16a
With p30 10:4:1 compression, I'm planning on running
A 1 layer or 2 layer head gasket
& have aquired supertech flat face titanium valves

I'm planning on running Blox HSL competition cams
Specs are

Intake- 12.59 255 @.050

Exhaust-15.54 256@.050

Does anyone have any info about using these cams
And the ignition timing they used also along
With cam advancement/retarding?

Help is much appreciated

 

 

Its more than I would consider optimal but should be an improvement over your b16 cams. Typically a "stage 1" cam works best on a b16, HSL is more of a "stage 3" type camshaft.

 

yeah HSL is to much cam, you would have to rev forever to make power with that in a b16, i'd get a blox a or b if i were you

 

Yeah, I got a good deal on em, I'm planning on going poor mans r, Or sleeved b20v thanks for the input

 

Couldn't I set vtec lower that's what I hear you have to do with these cams anyways, heard 4500-4800 rpm, I'm running exedy 9.5 lb flywheel & ctr crank pulley, hopefully those will assist in spinning those revs

 

Get rid of that CTR crank pulley before your oil pump decides to take a random **** at some random rpm.

 

If you do that your car will fall flat on its face, power wise. Raising VTEC is the only way to use the cams and make power but at the expense of reliability and sky high powerband. You'll need at least a 12:1 compression 1.8L or a B20 ideally to really use those cams to any potential.

 

When you ran the HSL's in your B16 what did you find. This goes to others on here also. Results, not a internet opinion.

 

? Never heard of this problem with ctr crank pulley, anyone elaborate?

 

it isn't balanced right. if you want one get an ATI iirc. same thing but is balanced right.

search ctr crank pulley on google you'll find plenty of topics on it.

 

CTR pulley has no harmonic damper built into it. This means there is nothing there to control crank harmonics which eventually destroys your oil pump gear (banging it back & forth extremely fast). It's a race only part for engines that get frequent checks & rebuilds.

There is really no reason to get these lightweight crank pulley anyways when the flywheel weighs so much more...

 

This makes no sense at all...

The ATi pulley has a damper inside it. Not even the same thing whatsoever. It's a more effective (and expensive) damper than the OEM unit. They say it combats crank harmonics up to 10k rpm or something like that...

 

OP- what did you decide to do?

00Red - when you say sky high, how high are you thinking? Sorry, I am curious as to what kind of cams people are running for 8500+ rpm motor..

 

People run the cams by the motor modifications rather than a rpm number. I ran my buddy club 4s to 9300 on my 12.5:1 gsr

 

I realize this, but I am building a motor that I intend to rev the crap out of, and I am curious to see what others are using as far as cam profiles in cars that are revving 8500+ rpm. Most cars are not going to make power in the 8500-10000 rpm range without a proper set of cams..I am just trying to get an idea, and I figured this was a good forum to do so.

 

You should make your own thread with the details of your motor and what not. A lot of smart people with a lot of experience on here.

 

Will do. I was just checking on the OP's progress..

 

I have them in my B18C with CTR pistons. They are decent. I think I need head porting and a better intake manifold to help them breathe up top though. Head and exhaust changed nett'ed me around 10whp. These things like to flow.

 

You have the HSL cams? What are you winding the car out to?

Cool Thanks.

 

Do you have any videos @ idle by any chance?
Pretty good numbers

 

I have yet to decide
I still need to send my head out for assembly/resurfacing/port work
I think I'm gonna use them
According to the compression calculator
I should yeild around 11:5:1 hopefully that's enough
As long as they make more power then my stock b16 cams
But if not I'm gonna probably pick up some skunk2 tuner 2 or pro 2
But idk I don't wanna drop more money on cams
Trying to get my car back up sucks
Having to roll in an astro van lol

 

Can't you just sell them if they do not work?

I know the feeling on trying to get a car back together, trust me, lol.
