Air intake temps on street car Just curious on what temps everyone gets on there street cars on & off boost .
im running 5.3/glide 14#
water to air IC , no heat exchanger , but a 30litre tank in boot that only pumps under boost.
seems no matter how much i boost the car even on a long pull air temps dont change much.
20 - 25* higher than ambient temp . boosting or not , under boost might climb 1 or 2*
???? seem right or not , i have seen some quarter mile runs where the air temps climb 50degrees over the quarter

That's what I've seen too. Those A2W setups almost seem to work too well, even with no water pumping. I always thought it was strange.
I'd see similar with A2A at 20-25 higher than ambient. It would drop a several degrees the first 2-3 seconds of a pull * But It would always climb 60-70 over ambient at 20-23lbs by the end of the 1/4.
My hot air car will max GM sensor just after the 1/8th at 250+. (i'm told those sensors aren't very accurate past 220 or so though) 19lbs on twin 64's.

I’m not currently flowing any water through my A2W core and highest I’ve seen is 115, if I put water in it’ll barely be over ambient.
My tr1245 A2A would do exactly what is stated above, it would drop a few degrees at speed then start to rise.

I picked up a 99 Camaro recently that uses a billet S484 on forged LS1 with an a2w frozen boost cooler and the previous owner said the same.
With ambient temp. water at 12-13 lbs. at the track he would only see a rise in temps of 5-10 degrees over ambient.
On the street at 10 lbs. the temp rarely got over ambient again with ambient temp water.
I think the combination of aluminum and water make for an excellent heat sink, I could be wrong, we'll see when I turn it up.

Verdad Gallardo I can't wait to add some ice and see how well it works with more boost.
It's kill'n me! 
For ***** we tried the difference and it was 18-19* between ambient water and ice water on back to back passes at 30psi. Basically hardly even worth the effort to change the water when its cooler than most A2A anyways. On the street its basically not even worth turning the pump on as temps only get to like 100* on a 3 gear rip. Not blocking the radiator was the biggest reason to switch for me, car runs substantially cooler now and allowed me to drop more weight with a smaller rad and fan setup. The A2A core weighed a good bit more than A2W core as well, plus it involved more piping. Didnt hurt that I moved the intercooler weight a good bit further back since I’m aiming for as close as I can get to 60% rear bias in a sub 2600lb car.
Believe Zack Brown did some nice testing on the efficiency of upgrading from the 3/4 to using true 1" ID fittings. 1" hose on the rule 2000. (standard china A2W core). Went from 10.75 LPM to 16 LPM! @ 13.5 v Looped lines with no core only flowed 18-18.5. So 1" ID fittings alone on the same hose/pump/voltage were worth 5-6lpm more flow. (thats a china meter he was stating GPM in his test, but looks like LPM on the tester?) if its another 5-6gpm that's pretty substantial!
Even the small type 3 frozen boost core seems to outperform the A2A units!
revised 1"
Has the nice pre/post IC gauge.

That meter likely was GPM and not LPM. I haven't gotten to play with any of it personally yet. Just been on various ride alongs and helped with installs.
Is that rated open flow? Even the Rule2000 is rated at 2000 GPH or 33gpm. But system flow with Open 1" lines only flowed 18-18.5 gpm on a meter. Curious what you'd see for actual system flow VS rated. Different class of pumps all together I suppose! Wonder if spending the money on crazy pump like that and running the "budget" core is the way to go. I was thinking the larger cores aren't much more anyway. Grab a standard 2000hp core, cheap pump rule pump, and go. But if you can exchange the water 2-3 times faster the monster pump... All good stuff to think on. I'll have to see how much $ is in the bucket when I get there and decide.

Ah Gotcaha. The rule 2000 I looked up was just under $100 and looked like cheap harbor freight junk.
The EWP150 was almost $500 once you added in the controller. And the pump was $284.
