Brian Crower Stage 1 Cams

I'll leave at just that

So if you know what your doing and not some kid in theres moms drive way you will be banned for your opinion. Thats how I'm reading this. Sure I can how people would think DAmotorsport is a shop, and I dont know if he is or not. I also don't think StormTrooper is a guy walking around in a white suit, its just a name.

And I own a business and don't consider the fee to be vendor here small. There are a lot of options for that money in terms of advertising and the moderators here need to make it appealing to pay the fee.

@Dimman
I wouldn't necessarily call it an exclusive. These simply have a higher potential to go toward the first on the market. Shit they have to start somewhere.

I believe I have one of the first set of HKS SP coilovers, doesn't mean I'm in cohoots with HKS. Just means I happened to be one of the first to place an order.

A couple things to keep in mind, besides the obvious fact this engine has direct injection. I don't know what the valve angle is, but steeper valve angle = better possibilities for head flow. Basically, there's a tradeoff between charge motion and flow, but the tradeoff line "moves outward" with a steeper valve angle. Maybe the valve angle is advantageous (or maybe not).

There's more to a cam than a duration--the duration is only the length of the event. The timing is critical. Remember, with dual AVCS we can retard intake closing timing for higher volumetric efficiency, and adjust the exhaust valve timing for either earlier blowdown (advance cam) or later evacuation of gases (retard cam).

In most cases for an n/a engine the number one determining factor of high speed performance for a cam is closing timing of the intake valve. It sets the trapped mass (effective volume), the pressure drop across the intake valve (filling capability and dynamic effect), filling time, and effective compression.



I'm sure you know this, but for everyone else: stiffer valve springs = more wasted engine output on friction. It's certainly an appropriate move to get stiffer springs, and I'm not saying you don't need stiffer ones in this case. But the stock ones are designed that way for a reason and you have to be careful about going overboard.

Also, for everyone else: brake torque (and thus power) = indicated torque - pumping - friction . Friction is basically a catch-all for anything that isn't related to combustion or gas exchange.

Friction screws you over in everything. It kills fuel economy, it kills torque and power.

I like how this entire post was put together to respond to a guy that misread the post he was responding to.

Overthinking this a bit really.

Anything else come of these?

VTEC does nothing for independence of intake and exhaust, even a SOHC non VTEC engine can have the intake and exhaust lobes altered independently when the cam is being ground.

Any DOHC engine can adjust the cam phasing between intake and exhaust, if it doesn't have variable valve timing you do this manually with adjustable cam sprockets.

Our engines do have independent variable valve timing on the intake and exhaust cams, so the ECU can (and does) adjust them independently.

What VTEC does do that we can't do is give two different cam profiles for different lift and duration. It lets you run a very different grind for higher RPM use than the low RPM grind, that's why they can run much more aggressive cams and still be very streetable. I don't doubt that an FA20 could make more power than a K20, but the K20 will be way more civilized at low revs.

I do. Bolt-ons and cams and i'm at 250 whp. I'm making more than the car in this thread with a turbo AND cams and a ported head... all motor.

The FA20 has a long way to go before we see what it can really do, but i'm not so sure it will ever reach that level, mostly due to drivetrain losses.

perhaps measured at the motor it could make similar power though.


Anyways, i was looking forward to perhaps seeing an n/a dyno up in here. Unfortunate it's not here just yet

[wparsons]

You totally missed the point of my post...

Put cams equivalent to your high RPM lobes in the FA20, plus a GOOD header, good rest of the bolt ons and a good tune and I bet it'll make similar power. The big difference will be you can drive yours on the street, but the FA20 would probably be a bear in daily driving.

I have been talking to Robb at DAMotorsports for the past few weeks. I can call him and see if he has any updates for us

[Mathewgzlz]

SEMA is right around the corner. If things like this are going to be updated it'll probably be then.

[D K]

Do you have any data comparing stock cams to BC cams directly?
