... New CAMS being tested by NST ... Update ...

[NonStopTuning]

hmmm so when are these going to be tested on a GZE motor?

I would expect to see more power from these cams on a boosted engine, and would be happy to spend the money and time to do further R&D with these cams, but we can only take that notion seriously if the community takes these cams seriously and shows us some real support in the near future.

:D

Could you explain to me the difference between a tri flow cam and a plain jane 282 cam.

tri flow has staggered lobes (for 4valve engines only) so that it makes power in the low and mid ranges as well as top end power

Oh!
Im more of a visual person.... Any pics of the cams themselves?

Any intentions to compare these cams agaist Colt's 261 (non-triflow)cams. Apparently those yield 20whp on previous tests.

Thanks,

Mike did test those as well. They didnt put out that much more than stock. Post the dyno sheets for those Mike .

The 261-268 cams DO NOT make as much power as the new Tri Flow Cams, and they certainly do not provide gains in the low to mid range in the power band.

The Tri Flow Cams are definitely a step up when compared to the traditional camshaft design for the 4AG.

I don't want to step on anyone's toes or come off as arrogant in any way, so please do not missunderstand the following statement... It is my strong belief that the previous expectations that people have had for the old 261-268 were based on a lot of hearsay and very little actual test data. The very small amount of actual test data that was out for the previous cams is very questionable at best. I am not going to list anything further on the subject, but feel free to stop by our showroom and I will show you the test data that we gathered with the cams.

In short, the Tri Flow cams are superior in power delivery, throttle response, and overall gains. PERIOD.

Thanks Mike:
And thank you for the invitation although I am in Puerto Rico. Can you expand on the Tri-Flow cam's idle?

Thanks,

Sorry Nativo, sometimes I forget that other 86garage members are not all Houstonians, as many of us here are.

The Tri Flow Cams have a very distinct sound at idle. Much more throaty, or deeper, than the Toyota cams. You can definitely tell the difference in the tone.

As far as the car and the engine's behaviour at idle... it is much more stable and predictable than I imagined it would be. I set the idle at 1000 rpm and it is steady and strong. Even after spirited driving, the engine just drops back to 1000 rpm and stays there. Very steady and very strong.

I drove the car around town for almost a week after the Tri Flow Cams went in and went to the post office, gas station, fast food drive throughs, etc. Jonas and I even had a little run-in with our local police officers near the NST showroom! The car does very well with these cams.


:D

For those who want the technical specs on the Tri Flow Camshafts...
Tri Flow Intake Cam Primary Lobes are 268deg 8.33mm lift
Tri Flow Intake Cam Secondary Lobes are 261deg 8.28mm lift
Exhaust Cam Lobes are 268deg 8.33mm lift


:D

sounds pretty basic not much changes in the two lobes... amazing how it makes the world of difference.. adding a good increase in power and torque.

THIS PLEASES ME!

Yes indeed. The change in design is not too drastic, and yet it makes a HUGE difference in the way the engine performs. All the gains in the low range and the impressive mid range is all due to this Tri Flow design. Traditional camshafts lose low end and mid range power and only help at the very end of the power band.

Tri Flow FTW!!!

Its funny how you say that traditional cams lose low and mid range. But when I installed my cam, it added power everywhere from 700-7k.

[CBR_TOY]

i think he meant the traditional colt cam.... but most cams do add power in certain areas

On average what you take off the bottom you can put some on top, and not do anything else. If you have a tight EPA cam and you install a mild aftermarket cam you can have gains of hp&tq with just a cam change accross the rpm range of your motor.
Most people just starting out over cam a motor and they used to over carb it too.
