Nice run, congrats ?

Does anyone have any before and after times with the only change being weight reduction? Really curious to see the difference.

I never made a pass with my weight reduction yet, have the EQT to install but will probably wind up doing some is38 passes before season is over. Going to get a 2nd wastegate to make the swap back n forth easy.

Every 100lbs is worth about a tenth.

Don't know if this is typcially though.

I know the rule of thumb, though it doesn’t always hold true.

Nice. About what I plan to do, though probably going to have a racing seat welded up to remove the driver seat and possibly a light weight battery.

IME, the gains are more significant on slower cars. But I don't have any scientific proof to back it up.

Nah, it's more likely the total power:weight impact vs "remove x lbs for y reduction in ET" weaker/slower vehicle or not.


To put it one way, take 100 lbs off of a Lotus Elise is very different than taking 100 lbs off of a Tesla Model X.


Taken to the Nth degree: Think about a transport truck hauling two full tandem trailers weighing what... 110,000 total lbs (?) In that case, you've got a 2800 lb engine producing just 450 or so horsepower and 1500 ft lbs revving out to 2000 RPMs. Fully loaded it'll do 0-60 in about 4 minutes, hauling around 45,000 lbs it'll do 0-60 in 2 minutes, and no trailer at about 20,000 lbs it can do it in 17-20 seconds.



Any improvement from weight reduction in quarter mile performance has got to be a percentage of total weight reduced vs the power available across the rev range (or total area under the curve, or whatever).

Can I use my dragy 1/4mi times, since we no longer have a 1/4mi track? They closed it down permanently, and the next closest track is over 1.5hrs away. Needless to say I can't get out there as often as I'd like

 

[Faceman]

Many of us have to drive 3+ hours to the nearest track, so I'd say no. There's a Dragy thread here for that info.

Closest track to me is 2:20, and worth the drive.

Take the drive to a dragstrip. Take a cooler/picnic and the family. It truly is a fun afternoon, and you get to see what your car can really do.

 

[Cliff p.]

I will eventually. I stand corrected on distance. The closest actual dragstrip is 4hrs away. The road course they sometimes use as a dragstrip is 1.5hrs away.



Probably going to Tuscon in April/May.

 

[pdisguise]

Going tomorrow. Was able to pull out 169.6lbs. Running open cutout so debating on if I feel like pulling the catback.
