So here's something silly. Over on the hptuners forum, some guys were talking about the possibility of creating a tune that would simulate the sound of a "lopey" V8/dragster cam (basically, by radically phasing the cams, to create a lot of overlap at idle). I did come up with something pretty close, after a little experimenting:

I figured someone here might get a kick out of it too. It was just too obnoxious and silly for me to actually leave it though..

I actually saw that.... But a 4 cyl. with a loppy cam? It may get the Vettes and Porsches to quit wanting to race all the time!! :lol: Actually, is it hard to learn hptuners? I'm thinking about buying it because I can't find anyone near me in Detroit to tune my car for me! :brentil:

Not that long a drive to Pwerks...
He can remote tune also.

This is called a ghost cam tune on the new mustangs and camaros also. To make them sound like they have lopey cams...not for me.

That sounds like an old farm tractor. Not a good sound on a 4 cyl.

sounded like someone rattling a can with a walnut in it. Pretty damn cool actually. I switched cams 4 times in my vette over the coarse of 3 years trying to get the right sound and performance. I was just fixin to do it again when I decided to sell it. neat idea. I probably would have left it for a few days just for the heck of it. nice work. I thought it was awesome. PS. the last cam in had was a thumper and I was able to advance the timing enough to get some real nice off the line torque. sounded awesome too.

Hi there!

Neat idea, cool execution.

That's fine for showing it off, but I'm guessing that much overlap will dump enough unburned fuel -- over time -- to do bad thing to the catalytic converter. So, be careful and use sparingly

Oh wow- I just noticed the replies, didn't get any email notices on this..?
Anyway, no CAT here, so no worries there. Also, the config only affects the tune up to 1,100 RPM, so once the gas is touched at all, it's back to running 100% completely normal (normal for my 400HP tune, that is.

Also, to The_Ghost: learning HPTuners was relatively, easy in my opinion. Of course, theres a bit of a learning curve with anything like this, but If you're at all technical, understand the fundamentals of engines (timing/advance, STOIC/AFR, etc), and willing to put the time in- there's more than enough info, demo videos, and tutorials on the HPT forums to get you up and running pretty quickly..

Good Luck!

so how do I go about doing this? I have an hp tuners and 07 turbo sky
