x2... i dont get it either. and if you are just looking for the sound as someone mentioned above, just go with a 110 or 111 lsa. itll produce roughly the same effect. enough for the untrained ear to beleive its bigger.

 

Yes I think 218 is too small too but I still like the name. I say you do it and prove all of us wrong if it is truly what you believe will work! Then that way hot chili will be what all the noobs recommend from the outset when all of these what cam should I get threads come along!

 

I put down 411 380 six speed 02 with a lid and slowmaster ad headers with the ASA and that fker was wicked

 

Well we know the hotcam itself does work. People have gotten some good results out of it with it's 9 degree intake/exhaust split and really low lift.

I really see no reason why faster ramp rates and high lift of something like XFI and XER lobes wouldn't make it a good thing into an even better thing?!

If these XFI/XER lobes DON'T provide AT LEAST 20hp gains or more power under the curve, then why does everyone bother with them? Doesn't make sense? If thats the case, why doesn't everyone just use XE lobes, there would be no advantage using anything else? See what I mean?

I would really like a PatrickG/PredatorZ type cam guru to comment or share their thoughts

If there are gains, i'll get this cam ground and share my results. Would make an awesome, modern, daily driver cam IMHO!

 

yes, the lobes are capable of making more power, but i think the hotcam is borderline too small to even bother, as in the gains would be minimal and go unnoticed except on a dynosheet. cam has -1* overlap, not what you call a big cam. i'd think the larger in duration you go the more you'd see from an aggressive lobe.

 

Why don't you go somewhere in the middle of the Hot Cam and the bigger XFI type grinds? How about a 226° .571"/230° .575" XE cam? Pick a 109°-111° LSA and it will chop like no tomorrow, and it will not kill springs.
BTW, that is my cam listed and I have it on a 109° LSA +0°. It idles harder than either the Hot Cam or the ASA .

 

do you have a dyno or track times? i am interested to see how the 109+0 affected the powercurve.

 

I will ask again why are you limiting yourself to 218 deg of inake duration?

 

The idea was to bring that hotcam into the future with new lobes. Not design a new cam but update an old one.

Hotcam is 219/228

XFI lobes jump from 218 to 224

So it had to be a 218/228 or a 224/228.

A 224/228 wouldn't resemble the original hotcam at all.

 

+1

Its actually looks like its only one XFI intake lobe and two XER exhaust lobes smaller than the 224/230 that PatG recommends

 

This is what I think you should try:

224/224 .609/.581 111+1 LSA,

Degree that cam at those valve events, use PP duals and 7.425 pushrod

Properly tuned with bolt ons that cam will make 400+ cam only

 

well i would not hang on to the hotcam just because of the name. You could run another 10 degrees of intake duration and do nothing but gain power. You would not lose driveabality going from a 218/228 vs a 228/228 but you would get a nice increase in power.

 

But loose trq, so there is a place for all cams, one has to decide on overall combo.
Look at my sig, care to challenge?

 

ooooo were would this vaccum line be located lol.... i have a couple mustang buddies who do that and it sounds kinda cool....

 

Thank you for commenting

 

lol not a chance in hell.
But i was just trying to say that he should bump up his intake duration since he was looking for another 20-30 horsepower over the hotcam and he did not really mention torque. I think a 228/228 would still give him plenty of rwtq but that is just me.

 

The main advantage of the newer lobes are their ramp rates. The thing is that if you're duration is so small you're only going to be able to take advantage of the faster ramp rates.

Example. Take a 1 inch diameter hose and push air through it at 40 psi for a minute. Now, take the same hose and flow 50 psi through it for the same amount of time. Obviously, the second example is going to flow a larger quantity of air.

Now, take a 3 inch diameter hose and flow 40 psi through it. It's obviously going to move more air than the 1 inch diameter hose at both PSI ratings. Then, take the same hose and flow 50 psi through it. That 3 inch hose with the 50 PSI is going to out flow everything you've tested so far.

Think of it as the larger the hose is the more air you have to push through it to reach that PSI rating. That increase is similar to the increase in cam duration. Increasing the duration allows you to flow more air into the cylinder because of the larger time / area of the hose it takes more air to reach the same PSI rating. The PSI rating is like the ramp rates. The faster traveling air is similar to going to a more aggresive lobe.

The thing is though that you can have something crazy like an LSK lobe on a 218 intake duration (I don't think LSks go that small, but example) and it will probably make more power than something on an XE lobe. The thing is that if you step that up to say a 225 XFI you'll probably make the same amount of power or more than the 218 LSK with less valve train wear. It's all a balancing act. Then, you have to throw in valve events, DCR calculations, and VE to the mix and it gets complicated real fast. Predator Z and Patrick G are the two who I'd talk to about this. Predator Z already gave you his opinion and I'd stick with that.

 

I agree. Alot of the new, over-excited guys don't yet realize that some people want to minimize overlap and gas smell, and it's worth a smaller hp gain rather than maxing it out and smelling like you've been riding a motorcycle all day.

Predator-Z, I would love to discuss this with you a little more for my new car. PM coming.

 

Guys you are wasting your time with the GM "Hot Cam". Back in 98-00, we tried every way possible to get that cam to make power. It did alright, but nothing to write home about or waste a bunch of money trying to perfect.

Stick with the tried & true technology of today, and do not waste your money trying to pour syrup on a turd and call it a pancake.

 

Just letting everyone know what my xmas present will be

Comp Cams LSr cams (54-456-11):
219/227 .607/.614 112LSA

At least Comp thinks the idea had merit
