Talking Borla Headers fom COBB TUNING

Hello all,
Well, I finally got some money out of my deadbeat brother (j/k) He owes me for helping put him through College. I never ask for the money, but he always pays little by little. Well, surprises never cease, he gave me a sizeable donation to the "makemyimprezaabadass" fund. The only headers I have ever heard about are the ones Mike Shields was doing...done...I don't know and the Borla. Cobb Tuning has ceramic coated stainless ones. They look great, anyone have them? Any word on them? The even sell new hanger grommets. Any help I would appreciate it... as for the rest of the exhaust, the boys at Rallispec should expect a call very soon!!
After that, I want to see how far I can go naturally aspirated. Do you think Extrude-honing the manifold would help? If so, the red STi one would look real nice on my Brilliant Red 98. How about the SPO intakes? Opinions, experiences?
And all the little doo-dads are all within reach now, clears, rear wing, etc. As for wheels, I really like the Advan Model 6 in gold from COBB, especially wrapped in some Pole Positions.
So, please let me know your ideas, experiences and opinions. Sorry for the rambling, but when your mod budget is ressurected from the dead, you tend to get REAL happy!!

Thanks again,
Doug

Yeah, I don't think you can do it but I think that you would get better responses in the tech forun.

MRT filter + stock intake from MAF to TB + Borla headers + SPT muffler
=
15.620 1/4 mile
first time ever.
good/bad-you decide, just keep it to yourself, Im not a drag racer and Im sure any 'good' drag racer could do better. There is ABUNDANT torque in my car.


+ intake + S-AFC
=
much faster

+
the computer that someone needs to develop really soon + Rallispec exhaust
-
S-AFC - SPT muffler
=
faster still

Question

Eric..what was the mph from that 1/4 mile run? Mph is the easiest way to see gains in horsepower and I just want to see how different it is from a stock car, thanks.

The mph on the 15.620 run was 86.89.

I'm seat of the pants estimating about 185-190 HP and similar torque. What do you think. Comparison wise to Richard West's stock engine, we both drew the same conclusion. Its atleast very near those numbers. At this weekends ProSolo there was a very low speed turn-around 270, I was able to easily pull second thru it, he could not. When I was at the lowest point on the tach in that corner, I was around 1800 RPM.

If I get the time, I will figure out how to use my friends Gtech and get its numbers for HP. And when GEEZ! releases G-Dyno I will test it again. Hopefully I will get some more goodies, like the pulley that I forgot to mention in the above post.

It all depends on temp, elevation and all those other good variables. My buddy was an f body owner and the atlanta f body page has some neat calculators. You can get there by going to the main page www.f-body.com then going to the atlanta page. Anyway when I ran my car at the strip last year it went 16.1s at best of 83.93, so your 3mph is a nice increase to see. When I put my numbers in (altitude, humidity, temp, pressure, car weight (3180 my in it 3/4 tank gas) I came up with 147hp. Your ET and mph at my track would have put you at 163hp. We have to remember that these are ballpark--but seeing an increase of 16hp over my stock car is pretty good I think. You can play around with what the conditions we like, but I wouldn't mind an extra 16 horses to play with .
