Topgunz Rotrex Kit Texas Build.

FrankEtier

Been running the Z for a little over a week now with the kit, about 200 miles on car since startup. Last night I uploaded Eugene's Flex Fuel tune and headed over to Kroger for some E-85. Seems odd that the grocery store gas station is known around here for the best E-85. When I hit the pump I was one dot on the gauge below 1/4 tank with 93. I added 10 gallons of E-85 to see how things went. Right at startup the content registered at E-67 per the photo and about 5-10 minutes later it settled out at E-58. Drove home the 8 miles uneventful with no crazy pulls or anything. Right off I can tell the exhaust will not be near as offensive of a smell as with 93 so that's a win! Looking forward to getting the content closer to E-85 as I burn off this mixture and upping the boost to my goal of 15 psi.

Other upcoming slight changes include adding a catch can setup and PCV delete so we can change the tune up from Speed Density to Mass Air Flow. Should have the parts to make that change in next couple days. Also I'm going to experiment with routing the BOV discharge out of the radiator area and under the car. Hopefully that will help with the temps that have creeped up.

Trying to get on a dyno later in October after I'm satisfied that everything is stable and running good.

So... how does the kit sound? Is there any of the pissed-off-tweety-bird zero boost BOV flutter? I'm running Aarons Gen II Ace kit & I have that flutter really bad. I'm considering upgrading to this kit, but def don't want the flutter.

I know you prefer to hear this from the customers mouth instead of the manufacturer. But, yes it is near non-existent. John Wheeler is the only person to say he can hear it when he tries (or at least has fed that information back to me).

If you want that noise gone on the Ace kit, then add that K&N pancake filter (RX-4130-1) on there and it will be next to gone also, at the expense of some power and needing to remove and reinstall the kit for install and cleaning.

This noise was a non issue on my Gen 1 kits because I sent every kit with that K&N filter and everyone used it and everyone was very happy. Up until 600whp became the new norm and everyone wanted to run just a turboguard to get there

When my car was making 680whp @ close to 17 psi with the V3 and turboguard, it had zero bov flutter. It wasn't until I went to the V2 and 19 psi did that I get flutter and it was bad.

No offensive sounds. Supercharger whine is audible but I like that sound. BOV exhaust is audible as well but I wouldn’t say it sounds bad.

By this response it appears he isn't aware of the sound you guys are describing, meaning, its not prevalent enough to be audible.

The BOV sound he is referring to is the straight "Afterburner" dump.
