20,000 rpm eaton blower........Civic si.
OK guys whats up im new and got a question.
The reason im here is because the guys over at 8th civic are all kinda bunch of ({*})'s when it comes to spinning the blower faster then a 3" bp..........
ok so i have a all the goodies, 1000cc inj's custom 3.5" cai. skunk2 header, 3" full race exhaust, custom 2" blower spacer (to fit my 3.5" thick AC core) custom supercharger inlet, custom supercharger oil cooler, ported blower etc.... blah blah blah.
Im gonna be running a 6.37 cp and 2.8 bp.... noting right.... well my engine spins at 8600 rpm that puts the blower around 20,000 rpm +/-.
I searched a lil bit but did not find much.
I want some solid advice to what you guys have done or think.

Most people here dont take their motor past 7500-8000. Not sure what blower you have but im sure that spinning it that fast will raise your air temps through the roof. I would ask Eaton. Alot of times these guys have charts that will tell you what the optimum pulley would be for a given redline

The working limit seems to be 18,000 but nobody that i'm aware of has actually blown one up from sheer rpms. We've used 2.5" pullies with a 6" crank for a long time, with 7500ish redlines. Your setup will be spinning higher than anybody here has actually gone, so I'm afraid we won't be of much help.

pushing the limits just to push the limits is counter-intuitive. Pushing the limits because you have evidence that suggests that there's potential for improvement is both beneficial and informative for the community as a whole. You seem to be treading thinly on the former with your idea. My best advice for you is not to push the limits of the m62. At least not in the way you're planning.

Well im just taking it one step further then ones before me lol. I have evidence that it will work im just using you guy as another form of it. And im not just pushing it just to push it. I would like to be the first 8th gen civic to break 400 whp......The guy to beat right now is running 371 with a bit smaller aftercooler and a 3" pulley, Im hoping my custom work and parts and .20 smaller pulley will push me the extra 29 hp. I kno... thats a lot of hp that high up on a sc.

And im sorry but it is proven with the k20 the bigger exhaust the more hp. I would kill my high end if i was to go smaller. i would stop making hp at like 7500 rmp.

if you're going to use an eaton m62, then you'll also need to worry about keeping those air inlet temps cool. They are very easy to heat soak with any pulley smaller than 3". I'm not sure if there's other versions of the m62 besides the one that came with the ss/sc models, but I would imagine that you would still need to install a rather large heat exchanger.

I have a 3.5" aftercooler and i have a custom oil cooler to cool the oil in the blower, I have done a test with a heat gun on the snout and it is nuts how much heat that produces.
