Air Intake Temps- Stillen SC
 

Just sharing this vid.....Seb @ Specialty Z just tuned a Stillen SC'd 370Z over the weekend...this car supposedly has the Frozenboost Heat Exchanger and reached intake air temps of 200*F on a dyno pass. According to Seb the fluid in the reservoir was cool to the touch, so there is obviously inefficiency elsewhere. Supports the argument that the intake plenum is too small to cool the air.



Ive heard that typically TT kits have AIT's of around 120-130 max on a hot day.

That got hot fast!

And he only hit 8.4psi max!! At 10 it would be 225+!!

Sounds like the pump isn't working. Did they verify that the water was circulating? Grabbing hold of the inlet and outlet hose to the plenum should verify that the pump is moving water. If both are the same temp then the flow is no go.

Seb also sent me this video last night. That is why either e85 or some type of meth kit is critical for the Stillen kit, water cooled of course. We also discussed the air to air and he said that it would drastically take down the temps as Aaron has previously said. Our kit being water cooled is a MAJOR flaw. I will also be installing a temp sensor like the guy in the video did, where the old MAP sensor goes to test this as well.

Ill take a video of my A2A setup and show no more than a 15* increase in temps. So a 70 degree day and your temps entering the plenum are a cool 85* or so.

that would be awesome man!! please do so :)

can't remember are you running pump fuel or e85?

I'm on e85. Which cools it even more once in the combustion chamber, but iats will still be the same as pump.

Keep me posted on this mod....I am interested in also doing this...This vid has me very concerned about the AIT's.

I had a massive front intercooler on my R33 Skyline (single turbo running 400hp 1.2 bar) and used to monitor IAT , I would often see 130+ and we dont get really hot days here in the UK. I would expect see even higher temperatures on the dyno.

Of course the a2a kits will cool down much quicker than the water cooled kits which will hold the temperature longer as will all the pipework that sits along the front of the engine of these kits

I think a gauge perferably with a warning is essential

Sorry to dig up an old thread. But I'm very keen to know the ambient air temp on the day?

*edit* Also for those unaware, Seb posted that they found the SC unit had unusually tight bearings, and once that was rectified, temps dropped by 50-60f. */edit*

Just finished doing the Stillen install myself with a 9 PSI pulley and given the crazy summer we're in at the moment 30-40c and occasional heatwaves of 40c+ (104f+) I'm getting very concerned about reliability. Car didn't make that much power (about 360rwhp) and Tuner told me he couldn't advance timing past 13 without pinging.

I'm also looking to install a AIT sensor post-intercooler and Seb is doing an e-Tune for me in a week or two.

Honestly just kicking myself for not going A2A the first time, and while that most likely is on the books, that won't be happening for another year I think.

Ur edit is correct with what Seb disclosed on his follow up in reference to the this video. Are u on the Frozen boost or The Stillen Heat Exchanger?

FrozenBoost. Except I may have gone a little crazy with it...

Awesome! I'm in the middle of my SC install with the frozenboost. Crossed my mind to add a couple fans to pull the air through, but never got beyond the idea.

Oh and you won't fit that drain valve on the bottom unless you trim the bottom of your bumper cover and possibly the undertray. Put the plug back in ;)

Honestly I was just messing around. Figured it couldn't hurt to try and might be fun/interesting lol. And given how high I mounted that Exchanger I don't have any issues with that drain tap. Oh, and I got this kit second hand, didn't come with the plug heh.

Forgive some of the photos, as they were mostly taken during the mock up phases. But I had to create a lot of clearance to make those damn fans fit, it was a very tight fit. Exchanger is kissing the front bar, and there about 10mm clearance from rear of fan to PS & Oil Coolers. PS Cooler had to come back a bit, had to cut some plastic where the lines come in and take the OEM brackets bend/flip and work some magic on them. Oil Cooler now sits on flush with Radiator Support... and it was just one extra Relay for the fans, they draw about 30A.
