If your intercooler makes your car overheat, you are locating or ducting it incorrectly.

I installed it exactly as the instructions stated.

Yes, but you said it was from TDR. Not exactly the best name in product development.

Take a bunch of detailed pictures of the bumper mouth opening and around the intercooler. Let's see if we might could come up with something useful for you.

I never responded to this. I apologize sixshooter. Next time I'm up at my shop (my parents) where it is I shall take a lot of pics. Maybe you gentlemen can find something that I'm missing.

On another note, I bought a smaller pulley for the SC today, got a 65mm. No idea what's on there right now, but if I had to guess it's the biggest one (77.5 I believe?). Should go from ~6psi to 12. Going to wait to install that until after the MS3, and I have a decent tune with stock pulley first.

I have a tuning question if anyone can answer it. The current tune on my FM link is solid in terms of being knock free. I can just plug those numbers into the MS3 and have a good timing map right? I know this sounds like a silly question, but I just want to make sure. Of course fueling and general drivability are another matter.

What size is your crank pulley?

I was getting 8 psi with a 110 - 65 setup.
130 - 65 gave me 14, and I got 18.5 with 150 - 65.

DO NOT get a 150 mm crank pulley. It over-revs the charger.

130/65 is what my ratio is gonna be.

If you are getting 6ish psi with a 130 - 77.5, you definitely have a leak somewhere.

It does spike to 9psi at redline. My boost gauge may be off. Idk.

Alright boys. Finally made it up and took some pics... Ignore the coolant all over the place, I put my 65mm pulley on and it shredded the belt almost immediately. I think my belt alignment is bad.

Alright guys, until summer I can't do anything about the overheating because well, it's not doing it anymore.

Anyway, I'm having another issue. I can't, for the life of me figure out why I'm only making 8PSI boost. I'm running a Hotside BRP MP62 supercharger with a TDR intercooler setup. I just upgraded from a 77.5mm pulley on the nose to a 65mm. In the past with the 77.5, it would make about 6psi until about 6000(ish) and then spike up to 8-9 (depending on IAT) and hold there to redline. Now, it jumps to 8PSI at around 2500, but never climbs from there. I'm 100% sure I'm not getting belt slip, I know what that feels like. I also know I don't have a vacuum leak, I did a vape leak test(at least it's good for something) and nothing came up. I'm also pulling the same vacuum that I always have (about 20hg at idle). I just can't figure out why. If the math is correct with the calculators, with the 65mm nose and 130mm crank (that's stock I believe?) it should be 12psi until ~6000 then jump to 14 to redline.

I would also like to add that the rotors are in extremely good condition. I think this supercharger has very low miles on it, because I remember when I pulled it apart to pain the charger + replace nose coupler + grease the needle bearings, the needle bearings were still very greasy and not dry, the casing itself didn't have any scoring on it, and the coupler looked in really good shape (still greased bearings and replaced coupler anyway).

Another side note... I am at 3,000ft, but that shouldn't equate to a 4PSI loss.

Double check cam timing?

I did that a long time ago after replacing the timing belt it was off a tooth and the car was running like traaaaash.

Could a worn out bypass valve cause such a condition? No idea how old it is, but I'm sure it's the OG one.

Did you ever find a resolution to the overheating issue?

Honestly I'm not sure. I have been driving it on and off for a while, and haven't had any overheating. However the weather has been under 80F. We are finally getting triple digits here in SoCal, so I guess I'll find out now.

However, the project dies here. I'm going to have to sell the car. I got into an accident on the 26th of December last year (yea, the day after Christmas) and completely fucked my back. I have 3 herniated disks in my neck and 5 in my lower back, so I can't work on the car anymore. it's a shame honestly, because It's almost complete. All it needed was the MS3X installed, COP's installed, suspension all the way around and a tune. No idea what I'm going to end up getting out it, probably not nearly enough. Oh well.

I am going to be driving the car just to see if the overheating problem got solved, as it does drive and rip tires just fine, just the old FM-Link ECU is garbage (can't use AC unless you are moving because it stalls the car). But regardless it's got to go. It's a shame too, it does haul ***.

[Edit]: I just realized those pictures I posted above I took the day before the accident. Lol. I remember that, the belt broke because my alignment was off after the SC pulley swap, and it tore the belt which took one of the hoses with it down below. My dad thought a bent a rod because the belt slinging around was hitting the hood and definitely sounded like a rod knock.

I used to have a massive back problem. Just walking was a major ordeal.
Went in for surgery, and my life was much better just 23 hours after the operation.
I went skiing on the 21st day after my surgery.... And never looked back.

Please do not get me wrong, but there is no point in accepting back pain and giving up. I got my life back and I would definitely recommend it to anyone who is in a position to make such compromises because of back problems.

I hope you feel better soon.

I have been to 4 doctors and sadly they all tell me the same thing 'I don't want to risk surgery because you might end up worse than you are now, and because you are so young(26) the risk isn't worth it'. It's super frustrating, but there isn't much I can do about it. I do have other hobbies and definitely haven't given up or anything like that, I just have to have a shift in hobbies. If this car was complete, I would keep it, but it's not and I don't have the money to be able to pay someone to finish it for me.

I had back surgery when I was younger than you. IIRC I was 23 or so. I'd had the issue for a while and it wasn't going away. Things are pretty touch and go with all the inflammation in the aftermath of an injury that your body may not have established a new baseline yet.

I hope you can find a good PM&R doc near you that specializes in rehab medicine because a good one of those will essentially work with you to exhaust every option before surgery and can help pave the way forward. I'd look one up or find recommendations for someone in your area. They're worth their weight in gold for this kind of thing.

On the plus side, there's decent literature to support that a herniated disc in the lower back can resolve within the year of symptoms, but I'm not sure if that study (SPORT Trial) accounts for trauma. If you herniated 5 discs in your lower back (i.e. lumbar spine) that means you herniated EVERY disc in your lumbar spine (except for maybe one depending on how they're counting).

My rec as someone that went through agony for years, though yours seems way ******* worse, is to find someone that can work with you for now without the knives. I really hope you heal fast man that ******* blows. Hopefully the other drivers insurance is still covering all the treatment.

Also, skiing 21 days after back surgery isn't typical lol.
