Forced induction temps?

[ML]

You got me thinking so I made something to help with temps...I was able to get my temps down 10 degrees during my last track session with about the same ambient temps with this:

Nice you fabricated your own heat shield.

Sir! What is going on here? Are you running twin electric superchargers? FMIC?

That's exactly what I'm running lol

How much boost are you running? Are you measuring boost?

Yes with oft and I have a p3 digital guage I'm pushing out 7.2 psi max.

I am currently not running a fmic. That was the whole reason for the question. Because these are ESC and not like a conventional turbo or SC. The idea was that if my charge temps are just about the same as those of other FI setups then there would be no need for me to use an intercooler but if my temps are higher than other setups then putting one on should be considered.

Typically compound boosting feeds compressed air into a secondary compressor, so 10psi and 10psi from each doesn’t equal 20 psi, but typically more like maybe 30psi. I don’t know about electric superchargers, but I would imagine it would be similar, which is why I asked.

Centrifugal chargers generate heat no matter what they are. They are compressing air and are operating at high rpms. Electric superchargers are typically not generating enough heat/boost at 2-3psi to need a FMIC. Some people with turbos or traditional superchargers don’t run an intercooler with 7psi either, but it is a good idea. In fact, most professional compound charging setups have two intercoolers after each charger, so air temps drop between chargers and after; the effect is better if the air feeding the second charger is not only compressed, but cooled. It leads to better efficiency on the second charger and IAT are better controlled. Obviously you aren’t running enough boost for you to consider that—just saying.

Reference video:

[dholloway543]

Sbd500x
14psi max

130f or 55c at worst
I want to pull air from out of the engine bay but idk how to do it without being obvious because I'm in California

You could have the filter sit behind the fog light bezel and just put like a half circle plastic on the top end of the filter to make it look like there's a fog light there.

I'm not quite sure how the science behind compound turbos work but when it comes to ESC . Cleetus McFarland on his youtube channel tested two torqamps in compound form each turbo alone made roughly 5 psi and together they made 8psi. It's what prompted me to do a twin ESC set up. My ESC alone made roughly 4psi each and together they make 7.2.

I watched the video. The electric supercharger is impressive in how it immediately spools the compressor. It seems like he made more power but less boost with the parallel setup versus the inline setup. Maybe the parallel setup flows better because there is two openings. Maybe it heats up the air less too, which is why there is less pressure aka boost.

Are you running E85 or anything to help keep the combustion chamber cool? In the end, you aren’t running a lot of boost, nor are you tracking the car and thus capable of heat soaking things, right? The converse of that argument is that a typical supercharger isn’t immediately going to max boost unless someone is revving it out, so there may be a potential for heat.

I don’t know man. In that video, the 100hp car made 200hp, so that seems efficient for 5psi so maybe temps are low, but a 300hp 86 seems like it would always need an intercooler.

Yea I'm on e85 and I think the problem with running in parallel is the surge. It's one of the things I spoke about with the developers of the toqueamp. They suggested that while the parallel set up does produce more air ultimately it's too much air for a 2 liter Engine, that a parallel set is best suited for 3.0 liter and above. So I ended up doing compound. Yes the spool up is quick and the tq is crazy downlow. Hopefully once it's all done I can do a comparison video of a buddy running a jrsc low boost pulley. Should be fair since we're both on e85 and both making peak 7psi only difference is I hit max boost at 3500rpm and taper down to 2psi redline and he hits max psi at 7000rpm.
