EBM , Auto , Premium , PP - How much does it weigh?

The scales were closed both outings to the track. I made changes to the car between visits. I gained 5.12 mph trap speed. I'm trying to figure out how significant that is.

What changes did you make?

Looks like the auto eb weighs 3524. Im guessing the premium can add a couple hundred due to heated seats, sub...

Installed a MAP intercooler and the MAP v4 e30 tune. The intercooler imo would not contribute much on a single pass. Staging lines were long, plenty of cool down time.

My 60 foot was .31 slower (track was slick)
My ET was .106 slower
Trap speed was 5.12 faster

So potentially, with a 230 lb driver I'm looking at race weight of about 3,950 lbs.

The e30 tune, imo, was the reason for the mph increase. Can you post your time slips? It will help show where the gain was.

Every tenth lost on the 60ft is two tenths on the big end. Using that logic, if you got a 1.8 60ft on your second run you would be 12.7 ish. Anytime I would screw up the 60ft, I would do the same thing you did, faster mph, slower et.
