So I just ordered my DRs, LCAs, EWP and A/C delete today. What kind of mph improvement do you think ill see from those power freeing mods/weight reduction? I'm also removing the rear seat belts this week too. Also, will added traction improve my mph? I was averaging about a 2.35 60' time on street tires and had to keep backing out of it in 1st. (first day they were open, DR guys weren't doing much better)

Car is a bolt on, cammed, stalled, geared LT1 with light hand porting on the heads.

 

Traction generally will not get you MPH.

It will reduce your ET.

So say your running 13.3 at 104 and a 2.3 60ft.

You get a better 60ft say a 1.9 the 4/10th on the line will be worth up to 6-7/10 on the top end.

You now run a 12.6 or 12.7 at 104/105mph.

MPH will be improved if you make more power.

 

the weight reduction combined with the EWP shoild get you about 1 MPH. And as Tom just said the traction will get you ET.

 

That wasn't the case for my car. Years ago first time out I did a best of 13.3 @103. Went back with only DR's and did 12.8 @105.

 

I figured that the excessive wheelspin through all of first and half of second would slow you down a tad up top.

 

Yep. I have changed nothing on my car many times and just by getting more traction the MPH improved 1-2 mph. 12.2s@113 to 12.1s@115

 

I gain 5 mph when I can leave off the transbrake on a race tire vs. Peddling it on a street tire. Also I see a .7-.8 second ET drop.

Remove front sway bar? Always a good idea.

With traction you could be .6 quicker in the 60'. So... about a second faster that whatever the hell you ran with a 2.35 60 foot.

 

I always lost MPH with a better 60' I'm not talking drastic differences but .3 was good for. 6 on the back end but I was always 2-3 MPH faster lighting em up from when i hooked well
