Treadstone TR8 vs TR8L

They are both the same height and thickness. The TR8L is 2'' wider though...

I have a TR8L. There's no reason it is only for low-boost applications, what the website says is it's a lower pressure loss core, meaning it's more efficient and less prone to pressure losses.

I have had the tr8 for the last year, and I just put on the tr8l last night.

I still have my front bumper off and I could probably test both over the next week. I have to clean a shitload of oil out of the tr8 first.

While there is less pressure loss, I don't know that you can make the blanket statement there is more efficiency...

The TR8 has an internal fin structure that is more dense, and therefore depending on the properties of the individual setup (turbo size/piping size, etc.), could possibly be more efficient at cooling the air charge, no?

[Chimmike]

My target with built motor will be 26psi daily, so a dense fin structure would cause some pressure loss via slowing down the flow. TR8L has a higher hp rating as well, which is why I went with it.

That is what I initially
thought by reading treadstones website.

Then I notice the tr8l had the higher hp rating.. so now I really dont know. Has anyone called treadstone and asked to speak with an engineer?

I guess I will try and get a couple of runs with one intercooler and swap out and get a couple more runs. But I'm only going to test between 18 and 20 psi..

It is pretty clear that the less dense fin structure will be inherently less efficient at heat transfer, which will be partially offset by the longer core.

The difference will almost certainly not be dramatic on BATs (probably in order of a couple of °F for most applications).

My suggestion: if you aren't going over 400whp then the TR8 is fine. If you want more then you will benefit from the lessor pressure drop of the TR8L or something larger.

No change in height, the TR8L is 2" longer compared to the TR8. I went with the TR8L and it is a very snug fit with no crash bar modification. Some inner honeycomb grill trimming was required for my set up.

I'm running the tr8l with cobb piping, its been great. Fitment is perfect.

I went a different route than just about everybody... TR8C. From what I've read it's supposedly in between the two in terms of pressure drop and cooling. Who knows.

How was fitment on the tr8c? And 3 or 6? I'm planning the same route and hoping that the center mounted inlet/outlet will allow for an intact crash bar.

the tr8c is exactly the same as the tr8, just centered end tanks instead of being at the bottom, hence C

Fitment can't be exactly the same if the mounting points are different. Geometry?
Edit: nvm reading fail

First gen 3... I got it to fit but it took some work. The end tanks are completely different on the C (not just the central in/out but the whole design) and the mounting points are narrower. I bent my brackets to make it work, or you could use bolt extenders - assuming you're using the Cobb brackets. If you're going custom it shouldn't be a problem. Do you have a Pu? If so it may not fit without cutting... mine has very little clearance on top or bottom.

That's what I thought but it isn't the case. The C has narrower mounting points (closer together) than the TR8 and TR8L, as well as 3" inlet/outlet instead of 2.5". Something to keep in mind for anyone using a pre-made piping kit. You don't want your car sitting for a week while you source 2.5-3" reducers like I did.

I have a 6 with cx racing fmic. I'll have to take a look under there and see how the tr8c's dimensions fit if I don't cut the crashbar.

Doesn't the TR8 and L fit the 6 without modification?

Like SnailD said, the core is the same, so if the other intercoolers fit the C will fit; it's just the mounting/piping that will be different.

Honestly I'm telling everyone who asks to just go with the L. The C is unproven compared to the other two and not worth the hassle IMHO.

I'm the other way, I have the L and wish I had opted for the standard tr8.

The tr8 is the best choice for anyone running 400hp or less IMO, the pressure drop isn't much more but the cooling capacity is much greater due to the staggered fin layout. The L has less pressure drop because it has less fins impeding flow. My BATs are usually <10deg above intake temps at full throttle but lots of guys talk about them being near ambient with the tr8.

[BigRedSpecial]

My point wasn't to steer towards the L instead of the TR8... I just meant go for one of the other two instead of the C.

lol no, you need to cut half the crashbar to make it fit.

The C would be more in the way of the foglights and housings unless you decide to relocate the horns and somehow move that oil cooler pipe or whatever that is on the drive side of the car.

the L works fine even if you do have to modify the 6's front end quite a bit to get it to fit.

[BigRedSpecial]

I see, I couldn't remember on the 6. All I had to go by were a few pictures on here

also will cool less, it's a trade off. Basing this off of my experience with water cooling loops, blocks designed for low pressure simply didn't perform as well as high pressure blocks though they killed flow so people needed pumps that could maintain pressure.

edit: just realized your post is 3 months old lolol oops.

[Sebs6]

Looking to get the tr8. What pipes are u guys running it with. Refuse to pay almost 700 for Cobb pipes. Thank you.

[fundream]

XSpower pipe look good

[Sebs6]

Thanks for the reply.
