No draw through's in my garage Charlie. Just the Stage, Monte, and truck and hopefully it will stay that way. So, you've been talking about quite a few mods that you've been testing, is your car running now? I've been curious to see some test results from one set up to another. How are you testing these different set ups? Dyno tuning, track times, flow benches, etc? There are a lot of people on this board that like to run their mouths about how "we are testing this and that in our shop" and such. I know the internet is an easy way for people to try to make themselves feel more important than they really are, and sometimes that's cool, I guess. BUT right now I have some things I'm trying to work out on a Hot Air that has already put down some serious low boost dyno numbers. With Tom @ Champion flaking out on things lately, I cant even get ahold of him. I need to put in some solid tunes and this debate over the intake in this section is so up and down and "secretive" and all over the place, Its a joke. We have an issue with knock after 22 psi and this knock shouldn't be there. I've tuned and done what I can but there's something else going on. I don't know if its the Champion hot air intake. It may be. I'm wondering if this intake was even tested at all before it was put out there as an "improvement." I don't know if compression ratio has an effect with one intake over another.
Why in this section, is there only a few people that will actually show results, ideas, and such? I've had my hand on plenty of builds in IC cars and yes I've come up with a few ideas that have made serious changes but most of my success with getting a car faster is from reading, then maye putting my own little twist on it. Or just doing exactly what someone else did because it was a great idea. This section lacks a lot because the Hot Air cars aren't very popular, there isn't a whole lot of people going fast, and quite frankly not a lot of people care about hot airs. Some of us do though. I used to IC them. With the difference that E85 makes in them, I see a lot of potential.
Just need some ACTUAL results.
Example, the TFW just dynoed a lightly modded car that switched from 100 octane to E85 while on the dyno. No changes, but 50 more HP at 471RWHP. Stock unopened motor, single Walbro, 6265, 80# injectors, THDP, cold air kit, 30psi.
What is the stock compression ratio in a Hot Air block? Is an original Hot Air intake designed, tested, and implemented because GM engineers tested it to match? Is changing a hot air intake hurting it? Is Tom's hogged out design just making a slush bowl effect and hurting flow? I think it is. But I have no way to directly test between the two.
