Blackwing Performance
Just bought my '02 Pewter A4 on 1/23/04. Beautiful car, but 2.73 gear sucks. Last Friday installed Blackwing + TB bypass. Sure was hard getting the star bolts back in at the front of the filter. Anyone have tool suggestions? Today I used GTech Pro to record 4.88 0-60 & 13.23 in 1/4; good launch; cool day. These #'s are nearly identical to pre Blackwing test. Might have picked up .05 in the 1/4. Does anyone have verified gains from the Blackwing? Not flaming the filter. It is a high quality piece, and I'm fairly certain it keeps more dirt out of the engine than stock.

Re: Blackwing Performance (imelectric)
My baseline run on my stock C5 M6 netted me 263 HP @ 5460 RPM & 281 ft-lb @ 4000 RPM (at around 75 mph) on the G-Tech. I've since added a Blackwing but haven't made a followup run. There's no straightaway long enough around here to do a 1/4 mile run without attracting too much attention, so I don't have 1/4 mile times. What did you see for max HP & Torque? I'll post my followup run when I have it...

Re: Blackwing Performance (imelectric)
The G-TECH PRO is nice, but it is not that accurate. I would not trust the numbers of it that much.
Get it on a dyno, if you want more accurate HP results.

Re: Blackwing Performance (AZC5)
Thanks, AZC5! This is a great forum! :)
Yea, it's a fun toy and I had been using the GTech to see what effect various mods do on my other cars. Just got the C5 a month ago and had to run it. The GTech is very consistant in its readings; my 95 Tahoe reads 117 HP consistanly over 6 runs at about 65 mph. My two runs with the C5 were 261 and 259 HP (one run in each direction in 2nd gear to 6000 RPM)...

Re: Blackwing Performance (99 MagRedVette)
I have a g-tech pro, and it is pretty accurate for times, but it is not that great for measuring HP.
My HP & TQ numbers are very different on the dyno, versus the g-tech.
0-60, 1/4mi = G-Tech pro is pretty accurate.
HP, TQ = G-Tech is not as accurate as a dyno.
In other words, dont tune with a G-Tech, tune on a dyno. Better results.

Re: Blackwing Performance (AZC5)
AZC5 :iagree:
I just use it for general trend data.
BTW: have you had your Vette dyno tuned? What were the results? Is it worth getting a stock C5 dyno tuned? What kind of improvement should I expect? Thanks!!!

As far as a Dyno tune, I bet you can squeeze some more out of it. Some people get as much as 20rwhp from it. Some see less.

Not likely true.

As far as performance gains, you should get a few more HP, but you wont get 20 or 30 :).

Re: Blackwing Performance (imelectric)
Wonder if you opened the cowl under the BW for cold air and installed the cover too. Otherwise you're sucking warm air from the engine bay and I wouldn't expect a big increase.

Re: Blackwing Performance (imelectric)
I installed a Blackwing with a cover and opended it up underneth with a little scoup. My best before with an a4 and 2.73s was 13.93 at 102 with a 60 ft of 2.14. After the install I ran a 13.59 at 105 with a 60 ft f 2.13. As far as the G-tech I used it at the track at the same time and it said I was running a 13.2 at 115. I can also break the tires loose now and couldn't before, plus hit a top speed of 170 MPH before I ran out of road. I feel it was the 1st thing anyone should do. For the record my 13.93 was with the zip tie mod and a stock filter.

Re: Blackwing Performance (myblackC5)
Gtech reports net horsepower and torque. It reports lower than a dyno because you're standing still on a dyno, you have actual drag in effect when the Gtech is measuring.
The Blackwing advertises a 15hp gain, that is maybe a .1 improvement in quarter mile times, probably too small to measure 0-60.

Re: Blackwing Performance (AZGASSER)
The stock system is very restrictive and I too ran 13.9x stock but I put on the blackwing and a cooler t-stat and times dropped to 13.6x and I do'nt think the t- stat contributed that much.

Re: Blackwing Performance (pettrix)
How are you guys running 13.6's and 13.9's with a 350-375 hp car???? I ran a 12.80 at 110 with an A4 with 3.15 ratio and CAI. My C4 with basically stock was running 13.30's-13.50's at 103-104. My car dynoed at 323 hp and 342 tq. Your time would suggest almost a 75-100 hp deficit unless your short times were like 2.3-2.5.
