    Took my 360 out to the drag strip near Denver last night (Bandimere) for an open track night. While it's no road course, it was still a lot of fun. I know most on here are probably not drag race fans but I thought I'd summarize my experience since I've not seen any other posts on drag racing. First, as far as my ET, my best time was a [email protected]h according to NHRA's conversion is a 12.5@113. Getting the 6 speed off the line was the toughest part. I played around a lot with tire pressures and RPMs trying to get more traction off the line but struggled with that for a bit since one lane was way stickier than the other. A couple times I bogged down coming off the line and a couple times I spun the tires pretty good. On my best run, I had just a little bit of tire spin and had a 2.09 60' time which I thought was pretty good. I think there is a little more in the car but not much. As night fell, the track cooled down and traction got worse. Don (ATBNM3) was there and got some video of the event. All in all it was a lot of fun.

    Andy, can you give us some idea as to what other cars were doing the time in? Also, I am not sure what you mean regarding NHRA conversion. Can you elaborate?

    Nberry -

    The track in Denver is listed at 5800 ft above sea level and there is a fair amount of horsepower loss up here. The NHRA conversion is a multiplier used to adjust times based on altitude and HP loss. Normally aspirated cars have more of a HP loss at altitude than forced induction cars and they take that into account as well. All tracks where they run NHRA events are at different altitudes, this allows you to get an apples to apples comparison of times. As an example, in the auto magazines and such they list the 1/4 mile time of a 360 at 12.8 seconds at a track at or near sea level, I will probably NEVER get my car to run that time up here. As far as other cars, a stock C4 and C5 vette was running high 14's to low 15's, there was a heavily modded Mitsu Evo that ran mid 12's, a Supra ran 15's, a modded SVT Mustang ran a 13.4.

    Hi Andy

    That sounds like alot of fun. So is car fully stock, any mod? I am planning to bring mine to the track next weekend to see how it will do with exhaust/straight pipe/ecu upgrade and intake. :)

    This is one of those places where you'd want the 360CS and the race mode to control the launch. The conversion of 12.5s is in the ballpark for a 360M. Good post!

    Andy, thanks for the post and looking forward to see the videos.

    I haven't get my 360 to the 1/4mile dragstrip and we will do it soon. Here is my experience:

    Kenny - my car has tubi exhaust and that's it. What kind of intake do you have?

    Launch control would be nice to have but part of the fun for me is figuring out how to get the car off the line without spinning.

    Jimmy - Cool man! Thanks for the link.

    No, I love to fix up cars, but never had a chance to run them at a dragstrip. Is it true that ca speedway is always too crowded? Just let me know when u feel like going. Thanks.

    Sounds like you had a good time. I use to drag race before I got into SCCA. Every 1/10 you get down on your 60' is 2/10 off your ET. What it seems like ios that you need to take some more air out of the rear tires. I would also ride the clutch just a bit so you dont have too much wheel spin. With the gearing on the 360 you shouldnt be leaving 3rd gear and if you do it should be right at the end. Let me know if that helps at all and what happens.

    GOOD LUCK

    never mind the clutch, that's just a consumable item...if you know anything about 360C racing....how's your driveshafts and gearbox output shafts.........

    I reckon 80% of race car transmission wear and stress is done by the standing start.....We now do rolling starts in the races, and wear and breakages have reduced dramatically.

    flame me, but aren't drags just guys being girls............?

    Not a flame but a comment. I have done both, drag and scca. Drag takes more skill that what people have come to think. Granted its nothing like doing a road course, but at the same time there are alot of varibles that give you a good time. Dont get me wrong, I would rather do a road course any day but there is alot more than just driving in a straight line.

    ferrarifixer - my car seems to be doing just fine after the event, drove it 50 miles back home afterwards, cleaned it up yesterday. Unfortunately, they won't let me do a rolling start at the drag strip...hahahahaha.

    AntonyR - I too prefer road courses to drag racing but enjoy any type of driving that challenges me and/or my car. I was chasing the track in the later part of the day as it cooled down. My first 3 runs (in the early evening) I was able to dial things in a bit w/o much change in the track, but once the sun goes down in CO, it cools down fast. I'm not sure of the gearing on my car but I was hitting 4th about 3/4 of the way down the track (perhaps due to the HP loss at altitude?)

    I am a HUGE fan of drag racing. My Z28 ran 13.5 @ 105.......but I am in Orlando Florida, sea-level, So I can't convert anything b/c that is the best the car will do. I know what your talking about trying to launch the six speed of the line, my Z is a six speed. Your 60' time should be like a 1.8 or 1.7, my car ran it's best time with a 2.2 60'. My buddy with his Z runs the same 1/4 mile time but his 60' time is a consistent 1.8 (automatic) and I beat him on the street all the time. So if you can get your 60' time down even a tenth your 1/4 time should drop 2 tenths. What kinda tires do you have on the car?? Do you burnout with them? Some need a burnout, some don't. I suggest not to lower the psi, because a street radial will bubble up in the center tread when the tire is low on air. I can explain further into detail if you would like, just ask, I'll even send you photos. Drag racing is my passion, I try to know eveything about it. If I had better tires my 60' time would be lower, but the are completely bald. So I am forced to baby it of the line. Did you try and feather the clutch at all? What rpms did you leave at? It is all relative, eveything you do, or don't do can cost you. Ex. I leave the line at about 1800~2000rpms, my car as lot of torque, you would benifit leaving at a higher rpm for the fact that the 360 motor has a lot more hp than torque, and its all in the top end. Sorry I typed so much, but I think I can tell you everything about drag racing and how to be better at it. I love it.
