Thread: Underhood/Intake Temps

I should have made the title of this thread Underhood/Intake/Post Supercharger Temps. Yes I know how to create an intake to get more ambient air and am currently working on that.

I've got a 2010 Camaro and I actually like driving the GP more since I'm so fascinated with any forced induction, turbo or supercharged. This is my first forced induction car and I love it.

Let me change up my initial question from my first post.
Has anyone recorded POST supercharger air temps from:
1. Any type of intercooler
2. Ram air hood with heat extractors
3. Full length headers (reducing boost psi due to better flow)
4. Different pulley sizes
5. E85 or meth injection
6. Any combination of the above

Thanks

Oh I know parkave. I kind of switched up what I was trying to get answers about mid thread.

Oh and I found there is a shop with a dyno close to me so I'm going to try and get a stock one then one after I do all the mods in the above post.

Hell no, you would have better luck on the SCCOA website. They have tons of tech and they also have the IAT mounted after the intercooler at the adapter elbow where it enters the LIM. Look for XR7Dave or Randy Connie or Duffy if they are still there. That board only goes back to about 02'.

a thought occurred to me this morning and if you have a thermocouple you could put a 3 way T at at the reference point for the MAP and boost dump solenoid (if you have one). I would do it but until I can actually get my car into boost it'll have to wait. I probably have a bad knock sensor so when I get time I'll fix that. I do have a 2 channel thermocouple thermometer that reads and records min/max and shows differential as well.

Was some time ago. Is cool to do and such, but worrying about a few degrees difference with intake pre-post SC is a waste of time imo... Might as well purchase the SNOUT cooler as well if you're looking to reduce temps. Get the fuel line cooler too... But all in all, you're still going to scan and still going to have to TUNE for dropped pulleys and MAX HP... Doesn't matter what iat is because you will adjust for it. The fueling, timing is where you're going to make the difference, not in 10-15* drop in temps. As for recording effects from different set up's... What you may want to do is just look at HP records and determine their setup and try and mimic it if you're looking for those levels of performance. Putting an ice block on a SC while dyno-ing doesn't count either, Lmao!

Bottom line is this... It's an old platform, and there aren't many NEW things that have been done.

Lastly, forget the plog unless going turbo, headers are best. Go 3" to the tails imo for best breathing but only benefits if opening the intake too, ie, GenV, N*, Stage* Heads, Cam, etc., in my most humble opinion...

: )

If it has been done before then I haven't seen it. Doesn't mean it doesn't exist but it means that every time I search for a technical explanation of something it's either met with 0 comments or some one paying fun and games and never getting to the point.

A few degrees difference is not a trivial matter it is something that should be a known. I am not a freaking newbie to engines and forced induction so your comments about cooling the supercharger snout and fuel line I find a little insulting. If you think that there is only a 10-15* drop in temp your mistaken I have seen temp swings over 100* in fact driving around in traffic yesterday I had intake temps in the 160* range and in the mid 80's when cruising. I changed up the system a bit and well see how it does today.

I am also not interested in mimicking anyone here, I like to learn and do my own thing, this is a hobby for me, therefore when someone asks a question that has some merit then answer or point them in the right direction. Do you guys purposely get on the board to act like little trolls?

As far as being an "old platform" and there aren't many "new" things? Engine technology has come a LONG way since I started playing with engines and go fast goodies. I consider these cars "late model" still to this day.

So here is what I plan on doing, I found this on the Aeroforce website and am planning on installing it soon. Screws into the intake mani like on the pics I posted above. Hooks right up to my aeroforce interceptor gauge and I can program it to read as "Boost Temp". Runs from -40 F to 275 F. After that I plan on recording different data on "boost temp", boost psi, knock retard, ambient air, and underhood temp (which I will use as the MAF reading on my Aero) while I'm all stock. Then try a few different experiments with air intakes and put in a 180 degree thermo (record data). Then I'm gonna get the front and rear power logs from ZZP (record data). Then the sseilmnop intercooler (record data). After that will be my baseline for trying 3.6-3.4 pulleys and making sure I'm pretty safe.

Sounds like a good plan. I would be interested in the results.

Just one thing, that zzp rear manifold isnt really needed as much as the 3in downpipe is needed. Mostly only turbo guys feel the need to use the rear log. Factory ones do seem to treat guys well when just running a 3in downpipe, the factory already has decent flow with the runners/log style design.

Hmm, I might need to rethink my plans maybe. I think the downpipe would be a good idea too, but if I got one I would get the 3" that would have to hook up to my stock 2.5" exhaust. I don't want to shell out the $600 or so for a full 3" exhaust.

Need the expert's opinions here: What's better
Rear power log from ZZP $200 into a full stock DP and stock exhaust
OR
Stock rear manifold with a ZZP 3" ( With cat) DP $225 necked down to 2.5" to fit my stock exhaust.
Please don't say both because I totally would if I could.

One night I read through that whole thread haha. Those photos are kind of dark, but I think the first is on top of the supercharger @ 83 degrees and the second is on what he said was the water neck @179 degrees?
When I first saw that I thought of "water neck" as the thermostat housing neck, but could he have meant the intercooler hot water outlet hose/neck?

the higher temperature is going to be the supercharger. I'm pretty sure the coolant neck is the outlet of the heated coolant.

there is a lot of good information spread through out that thread, but the pictures are a bit hard to decipher.

dont bother with either of those options. get the speed daddy headers on ebay. if you plan on doing an intercooler, the headers will work a lot better. and they run about 225.

Do the speed daddy headers have a place for the O2 sensor and not throw codes?
