rotormotor Posted February 10 Share Posted February 10 Pretty hefty exhaust leak that, my leak was just the gasket after the downpipe. If you after any emission stuff or airpump let me know Quote Link to comment Share on other sites More sharing options...

cletus Posted February 21 Share Posted February 21 Adrenaline r are good, I have a single 3.5" at the back on my car When I was doing noise testing they were a muffler that actually worked, rotaries usually needed a couple of them though. 1 Quote Link to comment Share on other sites More sharing options...
Vk304 Posted February 21 Author Share Posted February 21 Yes i have a maxfab 3.5 resonator in the front, cheers, if thats not enough i might have to run 2 resonators Quote Link to comment Share on other sites More sharing options...
rotormotor Posted February 23 Share Posted February 23 I have currently a twin pipe setup with resonators x2 and some JDM brand rear mufflers..mufflers hang far too low. Assume twin muffler etc quieten down the rotor moreso? Quote Link to comment Share on other sites More sharing options...
Vk304 Posted February 29 Author Share Posted February 29 Yea i currently have a surge tank and pump occupying the other side haha so thats not an option, but ill get around to doing it properly soon Quote Link to comment Share on other sites More sharing options...
dabuzz Posted March 12 Share Posted March 12 For exhaust, I removed a stainless adrenalin R off my RX4 as I couldn't stand the sound it made, horrible tinny and had a resonance at a certain RPM that just drilled into my head. Not a fan. I had a custom "Manawatu mufflers" mild steel boiler made to suit the space available, huge difference, really nice deep sound, slightly quieter, way happier. 1 Quote Link to comment Share on other sites More sharing options...

kiwi808 Posted April 20 Share Posted April 20 Probably the front Iron has cracked by the water jacket. It’s a common weak point from casting. That was the cause of my first rebuild. 1 Quote Link to comment Share on other sites More sharing options...
rotormotor Posted April 20 Share Posted April 20 My irons were all mint with no corrosion so I got lucky it seems. Welcome to rebuild time 1 Quote Link to comment Share on other sites More sharing options...
Vk304 Posted April 20 Author Share Posted April 20 Hope its not too bad but yea should be cool to see what its like, when it got real bad it sounded like 1 rotor was going and lots of backfiring and water pushing out of the radiator, did a compression test but nothing really stood out there, if its cracked there does that mean buy a new one or is there a way to save it?

rotormotor Posted April 20 Share Posted April 20 My engine builder said " Normally it's lack of coolant and I would replace ( if irons cracked). Not worth a dodgy repair taking everything out. I'd be putting it down to corrosion, rusty coolant passages my guess " 1 Quote Link to comment Share on other sites More sharing options...
shizzl Posted April 20 Share Posted April 20 Could be caused by a number of possibilities really, cracked housing, blown water seals, cracked plates. they usually still comp test fine too. Atleast you know it’ll be good after a rebuild 1 Quote Link to comment Share on other sites More sharing options...
kiwi808 Posted April 20 Share Posted April 20 My irons were mint with no corrosion at all but the metal between the water jackets and the seals is pretty small. Apparently it’s pretty common for it to break. 2 Quote Link to comment Share on other sites More sharing options...
shizzl Posted April 20 Share Posted April 20 Yup also common for the water seal groove to disappear 1 Quote Link to comment Share on other sites More sharing options...
Vk304 Posted April 20 Author Share Posted April 20 Yea we will see, just need to get a 54mm socket now and i can split it Quote Link to comment Share on other sites More sharing options...

rotormotor Posted Wednesday at 05:01 Share Posted Wednesday at 05:01 FYI FD irons and housings are the superior items, Irons more meat to port for one. 1 Quote Link to comment Share on other sites More sharing options...
