Hello all of you

many thanks.

I'm car #999. This was almost exactly one year ago with 3200 miles on the odometer. I have not run it since, although I'm pretty confident a solid 12.7@110 is possible now with well broken-in engine. If you look at the run where I miss-shifted and finished a 12.9@106...a 12.8 could of been had that night.

Good god! What kind of car was car #417? It hit the quarter mile in 12.756 seconds at 111.44 mph!

I'm also curious what cars #271 and #731 were too.

Those are VERY good times that you've managed with your beast! I wonder why Motor Trend hasn't been able to pull off those times!

I don't recall who I was racing...especially that first run...I was a bit nervous since that was my first time to drag race my beast. Probably a mustang or camaro, as I recall there was a musclecar shootout that night.

My car put 350HP to wheels on a dyno, 90% of other M5's that have been dynoed put down 325-340. So perhaps some examples are stronger than others.

Ramses: your car is VERY strong for a M5. You must've gotten the luck of the draw. I should try dyno'ing my car sometime. Does anyone know how I can go about in finding a reputable dyno shop in my area?

2001's X5/Z8 · 10th March 2002, 03:29

I ran 12.72 @112 in my Z8...............But I ran 12.28@114 in my mustang about 7 years ago.............

atomic80,

I'de suggest you call some local performance shops. Not necessarily euro shops, but also japanese and domestic shops. Ask them where they do their dyno tuning...that should get you to the right place.

2001's X5/Z8 · 11th March 2002, 20:14

my Z8 put out 364.7@6680 (HP) and 354.3@4800 (TQ) Before apples did my powerchip ecu upgrade, I am getting it dynoed again wed.....with the powerchip this time............I will post the results.............

2001's X5/Z8 · 11th March 2002, 20:19

by the way....my brother(zman) got his m5 dynoed before apples did his powerchip.....and I think he made 350hp.....and i'm not quite sure what his tq was.............but we are getting are cars dynoed wed......but now with the powerchips...........

Mike,

I saw zman's impressive dyno on another post. He is the only other member of this board outside myself with a stock/near stock M5 to post more than 342HP. Like I said earlier, roughly 90% have fallen in the 325-340 range.

Your Z8 is even more impressive. Figuring extremely conservative driveline loss, your topless beast has well over 410 horsepower AND well over 400 lb/ft. torque at the crank. That engine must of been hand assembled by ///M's best of the best.

What model dynometer did you and your brother use? What gear was your car in during the pull? zman was in 4th, just like me. I would like to see these monster dyno graphs...see if you can post up your graph or coax zman to post up his. We asked him in another discussion, but he hasn't done it yet.

Your 1/4 mile time is about what I'd expect, but the MPH is awesome. You ought to be able to shave another 2 tenths for a nice round 12.5 seconds. What was your 60ft. time?

Out of curiousity, are you using a G-tech to measure your performance?

Keep us posted on your updated numbers after the powerchip.

Congrats on those output numbers and 1/4 mile runs, and enjoy the PoWeR !

G-Tech is not thataccurate. The AP-22 is better.

In any case, that Z8 is FAST! Intersting to see how it will perform with the "Appled" chip applied

Gustav,

I'm very familiar with the G-tech since I own one. I've actually tested it's accuracy at the drag strip. The G-tech's time was consistantly (3 test runs) .1 seconds optimistic....that is the G-tech's time was .1 seconds better than what the timeslip from the track said. Not too bad for the money it costs. How much does the AP-22 cost? I have a friend in the market for a G-tech, maybe I can get him to get the AP-22 for comparison's sake.

The reason I mentioned the G-tech in my last post:

I wanted to get more info on that 112mph Mike got. With the G-tech you get the EXACT mph at the end of the 1/4 mile, BUT at race tracks they always average the speed in the last bits of distance (100 feet or so?). If you get 109mph at the track, the G-tech will probably show 112+

2001's X5/Z8 · 12th March 2002, 00:29

my 60' time on that run was 1.992...the dyno I used was either a 248c or 278c, can't remember for sure.........but the one I will be using on wed...with my bro......is not the same dyno.........i will get the info on that dyno for you...............we did thre runs in fourth and three runs in fifth..........and the highest was in fourth ....the lowest (351 hp) was in fifth..........the 1/4 mile time was on street radials...........I just ordered a set of drag radials which I will put on the stcok rear wheels when I recieve my HRE 540's ..........that should knock 2/10's off........
