Now if I ran on a Mustang dyno or on a cooler day, it could very well been higher, but not more than 400hp. Dave's dyno is the real deal, its not official until you run on Dave's dyno

Can't let Stomp and KTA be the only guys with 5" exhaust

Just to correct a few things. I have been on 8 different dyno's this year. 3 dynojets 3 mustangs 1 hybrid mustang and a dyno dynamics. For the most part there is very little difference. Like maybe 10hp. Bill you might have been lower on a mustang who knows?????

:-laf Every single one of them is different. I know that you are not being totally serious about "its not official until you run on Dave's dyno

:-laf" hence the

:-laf faces, but some people might actually believe that.
Someday I would like to make it back to an event like IRP or maybe another one where Dave has his dyno. That way some of you guys might respect the hard work and the money that I have spent to get where I am at today.
I still run 4" it seams to work just fine. I do however have a very interesting down pipe its 5" right off the turbo then there is a flared out 4" pipe welded to the 5" then 4" all the way back. It was a very tight fit between the tubo and the firewall. I wish I had a picture of it when it was out.
Bill get off the computer and get to working on your pickup so you can go flog the crap out of that turbo and give us some details. ( I like the pictures keep them coming)
