Title: What was your top Speed in Daytona
Post by: mcantuaria23 on March 07, 2007, 07:15:54 PM
Hi Guys, this year was one of the best races ever in Daytona, i have a lot of fun. The Question is What was your top Speed in Daytona? 600cc and 1000cc.. I run a 05 R6 full M4 exhaust with 107 rwhp and top out amazing 175 mph before get into the break zone T1. I saw some bike past by me so fast and i was looking in the speedometer  runing 175 feels like I was 60 if i compare with some other bikes.. ehehee..

Indicated, well, it's not actual.

2001 - 104HP GSXR600, I got 180...indicated.  I always figure that it's off about 10% easy, then figure for gearing.

Some actual calculations, assuming stock tire size:

Stock ratio 05 R6 at 14000 rpm would be 154 mph.
Stock ratio 07 GSXR 750 - 13000 rpm = 170mph
Stock ratio 06 GSXR 600 - 13500 rpm = 155 mph
Stock ratio 01 GSXR 600 - 13000 rpm = 163 mph

I was shifting into 6th 3/4 through the banking and taching out in the tri-oval at 7800 RPM:
03 Duc 1000SS re-geared (-3) 7800 rpm = 152 MPH

By any chance was there a radar gun positioned anywhere?

AHRMA usually has one.  AMA usually has one.  But they often get bad readings across start finish because of the banking.

Don't forget to factor in wheel spin.

You can calculate take into account rpm, drive ratios, gearing and tire circumference and still not have a correct top speed.

'91 FZR600 running with the Duc 1000ss and just a tick faster from the draft. No speedometer so I can only guess in the 150 range with stock gearing and running right at 12K RPM.

Gotta hand it to my engine builder Damian Weber for putting together an awesome motor.
