treadstone is not looking bad at all.

Problem? I was at 300 on 91 with no issues...

ca91 is even worse than what you run iirc
also you haven't tracked your car extensively (that I know of)

just my opinion, but I would use the most efficient heat exchanger if I was him, and the ebay cores are not gonna cut it. the "properly" finned one that we all discovered recently is great, and I love mine, but it's too small for G, and the bigger ones are all fail aids typical ebay stuff.

We are *supposedly* getting E85 this year so hopefully I won't have to do a meth setup.

I think ducting goes a long way with steady AITs as well seeing as I've had no issues thus far with heat soak.

Ducting is presumed.
But the discussion is about the best heat exchanger, or a really good one.
That's what G's build is about. Not something that "will work", but something that will work great and ball hard, and get all the boxers to drop

teehee

Right. G needs this guy's intercooler

I like welding things...

Buy the best/biggest core you think you can shoehorn in there, and then use your resources/friends to make it work with your piping.

This entire topic is being over discussed and most of you are shooting from the hip with an incomplete understanding of the topic. Posting pictures of fin design doesn't mean anything when you don't know what you're looking for. I legitimately don't mean to offend anyone but this horse is being beaten to death by people with small sticks.

Fin density is only part of it and YES you can have too many fins per inch.. Let's take a look at a company who's invested in conducting actual research and what changes they made to a product as a result of it.

ETS discovered that it was better to add more charge rows over their previous cores with a looser internal fin pack. Their increased FPI setup required more boost (creating more intake heat) to create the same power.

To theorize is an excellent start, but that doesn't make a very dense core a good choice.

I'm not sure who you're talking about here, but I promise you I've spent close to a month in the past year alone reading about not only the theory behind heat exchangers but the testing too.

I agree though: there is balance you want to achieve between flow and heat exchange efficiency.

I'll dig around for some testing logs I've done just a few months ago with 2 different intercoolers on the same car. 1 a process west with dense fin core adn the other a Fast Motorsports with ebay style placement and fin count.

They are otherwise identical, because FMS actually knocked off Process West completely. Down to the last detail. So the only real difference is the actual turbulator count and density and placement.

I think he's referring to this: https://www.miataturbo.net/diy-turbo...rcooler-83205/

Ahh I see. No worries either way, me and Bryan are cool so no harm.

I just didn't want him to think I was throwing out random stuff without any knowledge on the topic. (even though my "knowledge" isn't that great, I'll admit, I did do my homework like a good boy :giggle: and some testing of my own)

PS: I'll have to PM those logs cause I just realized I posted the names of the companies in question and I don't want to get into any drama with them either LOL

PPS: sorry if off topic, G. Don't kill me :love:

I did my best to address this as a discussion, not an individual, I think the point was still understood though. I almost sent you a text to tell you that your stick is just fine to me. :makeout:

Regardless, even after a decision is made about internal fin design EXTERNAL design can be considered, especially when tracking the car is a factor. Garrett cores for instance have a bad reputation in the DSM community for blocking flow to the radiator and causing overheating. My point is, the topic can go on forever at this rate - when the fact of the matter is he will likely not have a problem with the top 10 options out there.

Completely agreed
On both counts actually. That's the downside of the garrett core: it aint built to take much abuse from rocks/etc.
The vibrant on the other hand, to me seemed like it could take a hit from a hammer and not even dent. Bell was similarly strong.

Is no worries. Like I said, I was going to post it to my thread and see if I could cause drama ;)

Its not that I'm in love with that godspeed because its the bestest best intercooler ever, it just fit really really well with what I wanted to do back when I had the rotrex and the small Garrett. The EFR is a horse of a different color. I wouldn't re-buy the godspeed for this application. The Precision I have now is an amazing part. Even used and dirty its still glorious, its just "frigging massive" to put it lightly.

The treadstone is out ahead at this point simply due to a combination of fitment, price and quality. Its an OTS unit that is dimensionally similar to the one I had before and shouldnt require a lot of butchery to make it fit. I do still need to comb through the Bell catalog and see what's avalible before I make a decision, and welding something up is also on the table as well. I am also still poking around looking for pics of other options but well see how that goes.

Also, Fab, as much as it may sound like I'm talking smack about your intercoolers, I'm really not. They are great units Its just not exactly what I'm looking for at the moment. For what I'm looking to do the bigger IC just sits too far forward. I could probably make it fit where I want it, but I'd have to cut off the tabs, and then its not worth it at that point. I'm sure you know what I mean.

Also also, can make 300hp and will make 300hp are two totally different things. Remember the part where im a giant wuss? :party: I appreciate the comments though, I'm reading and enjoying all of it.

Built engine and no allofit? Disappoint :(

Also you mention thunder hill, who do you run with there. I went to Trackmasters last year and plan on returning again this year.

I think I've run with Trackmasters and NCRC? There is also another private group I've signed up with that runs T-Hill quite frequently but I've not run with them yet.

Sweet, I'll be down there in august with Trackmaster, try and get your junk ready by then :)

The 3.63 sender wasn't going to get here before the weekend so I cancelled it. Instead, I ordered the parts to mod a speedo sender. I'll get to installing it whenever I've got the trans out and drained again. Probably when the engine goes in. Hopefully installing this little gear isn't a huge pain in the ass. Good thing I have a couple extra senders.

It literally took me 5 minutes to switch out the sender gears. You shouldn't have any problems with it.
