Found a group called "Cold cams" they regrind cams with a "tri-flow" technology. Sounds extremely cool, and from what it shows on their website I'm thinking about trying it.

for those of you too lazy to open
TRI Flow Technology

The most common problems encountered when performance camshafts are installed are the loss of bottom end torque, poor idle quality and computer problems.

This phenomenon has been more and more prevalent with high-revving, multi-valve engines. When two valves open at the same time, there is twice as much room for the air to move through. Picture a vacuum hose that has a diameter of say 1". It could quite easily suck up marbles or small rocks. If that same vacuum was hooked up to a vacuum hose of say 5" diameters, what could it pick up? Maybe a feather, but the marbles and small rocks are totally out of the question. An engine works the same way!

When an engine is optimized for HIGH-RPM power, the LOW-RPM power will unfortunately have to be sacrificed... or will it?

What if someone could make a performance camshaft that could make better power at HIGH-RPM with a minimum low - rpm torque loss, without the use of a variable lift cam system?
Colt Cams has managed to do just this for virtually ANY multi-valve engine. By staggering the opening times of the two intake lobes, we have created a swirl in the system. The principle behind this design is to open the intake valves progressively. Opening one valve first allows the fuel to travel across the chamber at a greater velocity due to the smaller venturi action, it then helps pull in the second charge at a faster rate.

This gives the equivalent to the secondaries opening up in a carburetor. In turn, with the larger cam, the engine has better vacuum at idle since there is less overlap, throttle response is greatly increased, and turbocharged vehicles have noticed less lag and faster spool up time. Geoff's theories on the "Tri-flow" have been proven time and time again, on many different engines. The testing has proven the theory, and now it is time to let the world see the results.




Anyone try this before? Because I'm thinking of sending mine in. Also, is this BS? Or are they legit?



This might make Jordan happy..
They're based in CANADA!

Duds....It's dirt cheap.

Prime int 266° .355 L
Sec int 260° .355 L
EX 274° .365 L
The cost is $400.00 US for the pair

But I think that might be $800 since we have 4 cams total. Not too certain, i'll call them tomorrow.

I'm really considering it...I mean, by the way they made it sound, it would idle normal, and the low end torque would not be lost, and the high end power would be incredible. Plus the combustion would be optimal since they'll mix the fuel + air properly...
$800 is worth it IMO

Perhaps we could get a group discount if enough of us want to try it?

Plus we have to ship to canada. I'm on the border, maybe I could drive out to windsor and ship them out and save my self a couple bucks...

Crowler is $350 for all 4... Plus shipping...
Really?

Well, they cannot do the tri-flow technology though.. I mean the whole reason for this is when I get the turbo installed I want low end torque and not have to wait for the turbo to spool before I start to move. I would rather have an aggressive start.

If Crower can do that for $350 I'll send mine in tomorrow haha

For some really weird reason....I'm completely Okay with spending $550 regrinds, $175 for the cores, $700 for a full P&P job with larger valves, and $175 for the stock heads..Probably another couple hundred for the tools/ labor to have them installed. But after it's done my car would be so damn fun

you just have to adjust your timing and such you can advance timing to give Low end Retard to give high end... I may have that backwards...
Advancing the cams gives you better lower end
Retarding it would give you much better high end

But I want both...I want a strong high end without a weak low end.
I think tri-flow is the way to go

Crower can make you FI cams. You just have to ask. I found a website for a company in england that does ALOT of internal work for the 2.7L delta. They even have crower FI pistons and Rods. I will pm you a link if you request. All you have to do is talk to crower.

Theres alot more aftermarket support out there for Hyundai tiburons than the people of these Forums would lead you on to believe.

Its because of the site rules, most will go unoticed because people can post up their findings. Can't even link to the little brother site NGM for goodness sakes. (Some rules should be changed , Sponcers should just suck it up, or get more competative. Most have been selling the same thing since 2003. No new R&D, No new this or that, Pathetic.) END RANT
PM link please..

Geoff also mentioned that I must state if they are going to be meant for F/I in which case the grinds would be different....I'm not too sure..Do I want to spend $200 more for something which might not work as well as a proven regrinder's cams? Or should I invest in something which might fetch me more whp? I really want to know if anyone has tried these cams and if so how good are they?

Duffer has a set of F/I regrinds, he hasn't put them in yet and the specs are somewhere on NT..actively searching for them. But you wouldn't have any overlap with the tri flow design correct? 1 valve is opened at once for the intake side.

If you would look in to cam thread you will notice that colt cams is not a news to the site.

One member bought them and did comparison dyno of colt vs crower (both tests were done on low compression engine, but colt showed 5-8 hp more through the whole powerband.

These are the specks for cams that were done for tib
TRI FLOW cams for 2.7 delta

Primary intake Valve
218 duration
.365 lift

Secondary Intake
210 duration
.355 lift

Exhaust
218 duration
.365 lift

Can they handle 15-20 psi?

If so choosing which set of cams to go with is going to be very annoyingly difficult..

you should forget about the cams until you pass the 500 mark that for me nobody have pass before,leave your cams alone and live a happy life,modify something like cams before even test the stock ones with the turbo is a naive modification.im on 25 psi and stock cams,boost is free so i will increase the boost until something tell me there is no more power,then i will do something like cams or head.
Well, the main reason I wanted cams was to have more of an aggressive powerband..

Whoa whoa whoa whoa whoa...

Blanco says stay stock,
Duffer's going to install F/I cams,
shamansshark says do whatever you want because you'll still fail with F/I..

Zion has no ****ing clue what to do about cams...

This is such an easy decision...
