You be the qtp nut hanger and I'll be the tsp nut hanger. Until someone makes a good enough dyno comparison to satisfy you. lol

1 3/4" Headers vs 1 7/8" Headers ?!?!?
Make sure you get headers with ceramic coating. I found a penny size hole in front of the rear o2 sensor. I got the powder coated Hookers about 3-4 years ago. Now I got to replace them.
Oh yeah and I was on a stock tune with stock tires too. Last edited by 2002_z28_m6; Nov 9, 2008 at 02:49 PM.

Where did you run the car at? What was the temperature and humidity? Are all our mods exactly the same? How much gas did you have? How new were your tires, what brand were they and what psi were they? How much gas did you have in the tank? What was your race weight? What octane fuel? What brand of fuel? What % ethanol was in the fuel? What DA?
I could ask you about a million more questions, but you haven't even provided anything backing any of that up, so...
My car bone stock trapped 115 mph with a full tank of gas in July. Call me a liar on the internet. I swear it happened. My buddy saw it, too.
What I can tell you is your numbers aren't all that impressive in your signature for an M6 with a larger heads and cam package, especially if it's through a 10-bolt.

QTP vs. Pacesetter on a H/C car. No other changes. That's why I'm not surprised TSP could outperform extremely outdated (and tiny) Pacesetters. I've been satisfied for awhile.

All I'm trying to say is Pacesetters leave a lot on the table. On my dyno, it was just a header swap between Pacesetters and QTP's. QTP's blew them out of the water. I've proven my point without a doubt. You haven't proven anything, except that I'm wasting my time trying to help people that don't want to listen. Like I said, do what you want. It's not my car and it's not my money.
I'm sorry but you haven't proven anything but the fact that the qtps were better on whatever setup that is than the pacesetters. Get off your holier than thou pedestal already. The funny thing about this is that I haven't even been really pushing the larger size. I just said I have them and they are great for me. It's when I asked you to present some real evidence to support your claims and refute the current posted evidence is when you got your panties in a bunch and started taking offense. So until you produce your kooks 1 3/4 vs kooks 1 7/8, on a stock 346, back to back, dyno sheet, I don't think we have anything more to talk about. Thanks, it was amusing.

Whatever helps you sleep at night. Guys like you make your opposition look smart 
I voted 1 3/4 but with an MS4 1 7/8 should balance it out to be better... i have 1 7/8 on only bolt ons and it lacks torque down low but rockets up top.. id say 2-3 more HP uptop 10-20 less lb-ft down low- same torque as 1 3/4 above 3500 RPM though... i figure with heads and cam (3+ years down the road) the 1 7/8 will be more suitable
