No Limit 6.7 Intercooler Testing

I'm under the impression that boost is a measure of restriction and the stock cooler is very restrictive. I have sensors on both pipes and are recording boost lost on the output of the cooler with the 367 Turbo. I'm very interested in this cooler for flow alone. 100 Deg temperature drop would just be a bonus.

the cooler alone is right at 30% increase in flow verified on a bench, not to mention the increase in flow on the end tanks.

what are you seeing for pressure loss right now? ~10%?

 

[dseitler]

Around town and cruising I don't notice it at all. Towing I see it on a long pull and when I get on it hard like a interstate on ramp. About 10% when you first get into the boost hard.

correct which would follow with the early findings that the restriction is much more noticeably removed at lower rpm. these engines are so efficient, that they really notice restriction down low . similar to the findings of the 5" intake , the results are strikingly similar. there's just something about removing all low end restriction that makes response drastically better.

every No Limit product scares 6.7 rods all across north america!

how so??

 

[LovinPSDs]

how so??

All the huge down low power gains :evil Is that not the concern? Big Torque down low

That being said, the no limit products look like they would give me the EXACT truck I'd want. Super responsive, cool running, ect ect. I can't wait to get my hands on a 6.7

how does removing restriction down low make it harder on the rods? im not understanding...

also-tuning is way more refined now, popping rods isnt near as common

Exactly!

Removing restriction after the motor (heads, exhaust, etc ) and before (intake, intercooler, etc) are completely different.

Off topic but how is 38 psi with a stocker different than 38psi with say an s467.

I've always wondered just looking for a good explanation. I don't understand turbo maps. I is dumb.

with a boosted motor, if you have an intercooler that has less pressure drop, you're allowing more air (more dense) to be forced into the combustion chamber in turn creating a more volatile explosion which is more power. Freeing up backpressure allows the motor to do the same amount of work with less resistance .

air density in relation to heat, overall cfm

I see. Thanks.

Are you being serious?

And less backpressure too.

Bigger more efficient wheel= more cfm at lower speeds. Thus more more boost (restriction). That's why we have cams and ported heads and no limit ic and junk. For less restriction
