Will this Exhaust work with a turbo?

I thought I saw Gernby say it isn't designed for FI all his research into making it was specifically for NA.

I guess I will be selling it

You could try messing him, he is on the forum.

I will either sell it or throw it in the trash if I cannot get the money I want for it. I need a full 3inch with no cat. I let Patrick know at Urge that I was planning on FI according to him this is not a restriction and helps spool, however it will be a bottle neck on a turbo setup. I wasted 2k plus when I could have done a Sparrow 70mm and a sos test pipe. Oh well lesson learned.

Isn't the turbo the restriction? I'm puzzled why a exhaust designed to extract waste gas would be restrictive. I'm thinking it would help pull exhaust regardless of a turbo being here or not. Curious of the outcome is only to add more dangerous engineering knowledge.

I am running the Gernzhaust with a supercharger (375 WHP at 8k on AP1). I think in theory supercharger can benefit from exhaust scavenging, although on my tune we we'ren't able to bring vtec below 5.4k because of a resonance spike, so the results suggest that perhaps it wasn't the best idea.

But, as for as turbo theory goes, you don't want any backpressure whatsoever behind the turbo. SO, it doesn't make a lot of sense to have an exhaust behind the turbo which improves scavenging (it does so at the cost of some backpressure)

Anyone with some more knowledge want to chime in?

Wow! Great business strategy. That's messed up.

Go straight through, save yourself the heartache.
Melted catalyst, top end loss, elevated egt, burnt exhaust Valves, etc.

I always want the best #'s to, but I still run my EX valves at .011" no need to be itchin every last nickel. I see scavenging as icing on a cake (for NA). But if it has a higher chance to fail and make things possibly really bad (for FI), ... Doesn't make sense.

Unless you could fabricate a boost regulated 3-4" cut out on it....(since you already bought it of course) it could save some time, money, hassle of a complete swap. Just saying there are options that's all.

If you're gonna throw it in the trash I'd be interested in your rear section. I love my Gernpipe/scavenger and want to try one of the new Urge mufflers.

What?

Jay-P317

I am selling them. Not donating the set up. If I loose 2k so be it.
