Ended up making it out to Island Dragways this past weekend for some end of season passes.
Wondering what you pros think. suggestions for more trap speed? I wanna go faster!

For more trap I think you'd need more power. I think you could creep up on 12's with better 60 ft's. Maybe some 22" slicks

 

im sure 12 are possible on a 1.6ish short time, but i want more mph.
Im thinking about doing cams before spring. maybe pick up a few mph with some pro1's

 

I would get some cams and possibly a 3" cold air intake w/ the stack. Also I picked up 2-3mph by adding a golden eagle style rear diffuser. Might sound silly but it worked for me.

 

Cams and a 3" exhaust

 

ugh. is that true?! 2+mph from speed holes?

 

Yup. I just built my turbo motor and broke it in N/A and later on that year it went 13.8 @ 97-98> I got a deal for it way back in 06' so I put it on and literally that Friday the car went 13.6 @ 100 all within 7 days time. That is my experience with "speed holes" haha!

 

you could put a 200 shot on it and really have some fun

 

depending upon the size of the tires you used for your 2.0xx 60' you could add some smaller slicks to help the short time which will improve your mph and also reap the benefits of the smaller tires helping gearing; assuming it does not have you making an extra shift.

as for the ANECDOTAL(key word) experience about the guy picking up 2+ mph with modded rear bumper it is important to remember, correlation does not prove causation. there are many variables that can also help explain the disparities in the two runs and unless detailed notes were taken to help isolate what changes may have netted what results, this discussion becomes academic at best.

 

Sounds like a plan!

I was on 205/50/14 BFG's this time out, but ive been stalking FS spots looking for some slicks. you suggest 22"?

 

Everybody poops on the 22's. I've cut 1.61's in a ~200whp vw on 22x8x13 M&H.

 

my advice is not valid because there will be little, to no change in overall diameters between current tires and 22" slicks; your overall gearing should remain about the same. you still would have the potential to reduce your short time and pick up some mph but it will not be as quantitative as if the tires were also smaller.

your next series of choices kind of lay the foundation with how you should continue to modify your car. think about how you want to solve, "the need for speed" and try and think long term so that the most efficient compromises can be made. e.g. getting some 22" slicks should take care of you now but if your plans are to eventually toss an extra 100+ hp at the equation the task of traction will become more difficult.

so we ask you; what are your goals with this car? pending the response we can tailor some specific responses/compromises for you to consider.

 

After a few weeks of seeing a consistent increase in my mph I asked a friend if I could use his uncut rear bumper just as part of the experiment. Sure enough the E.T. got slower as did my mph. I was so intrigued as to what this was all about I went on a Sat which is dead here at my local track, just to hot lap and change bumpers back and forth.

However this is only my experience and perhaps others haven't seen the same results as me. Needless to say the "speed holes" are still on my car and will not come off any time soon.

As far as tires I would go with a 23" slick. Not only could it potentially pick up your mph now, it will benefit you in the future with more power and open up options for gearing changes.

 

^ if the op does not mind and you have the time slips from that particular day to post i would enjoy analyzing them. i predict there will be large enough variations within the runs that few people would put their credibility on the line and extrapolate how much the bumper was worth. i am not debating it helps but i suspect that the 60 foot and the da from each run factored more into the results that the bumper.

if this request is not satisfied ill drop this discussion by asking you not to forget, that the human factor is often the largest variable within many systems.

to the op:
try using this website; http://www.f-body.org/gears/
to help determine what gears you may want to use to help avoid extra shifting. also think about realistic long term goals to help reduce cost and time in switching many times. e.g. look at what others have been able to do under similar mods, weight and conditions.

 

I actually tried to find them today but since they were from 06' , I most likely threw them out as my setup is much different know. All I wanted to do was share my experience to help spread knowledge. Not defend myself against someone that may or may not have done similar testing.

As for 60' consistency, it ranged from 1.9 to 2.1 throughout the entire day in no particular order. I did a lot of bracket racing back then and consistency is key! Not saying I am the greatest driver ever, but the human factor is there and everyone misses a shift here and there.

Op, take it for what it's worth. If you choose to try it or not it's your decision. It worked well for me. Just take a look at some of these cars at import events across the country. Most of them have there own variations but the concept is still the same.
