I went to the track today to get some new times since i did headers and a catback.

SLP midlengths
SLP 20TL
Dynomax Bullet ORP

Old setup was stock exhuast with borla rear section non adjustable muffler.

My old ET was 13.464@102.61 1.951 60'
Old ET corrected: 13.148

New ET Is 13.204@105.83
New ET corrected: 12.804

I used the fbody.com elavation correction calculator and the adjusted elavation from the weather station at the track.

So the raw numbers show .26 gain in ET, but corrected it was more like .35

It was an awesome day, so many goats! The turbine powered car was awesome as well. I wish the weather would have been better so i coulda gotten a 12.9x timeslip, but those are the breaks.

Oh yeah, once again i redlighted in the brackets. I didn't do a good job driving today, all crappy RTs.

comments welcome,

Nice gains.

 

thanks wing

I forgot to add that i also pulled a 106.00 mph trap but it was on a 2.211 60'. The power is there, can't wait for the cam and waterpump.

 

how do you correct your et? is there a formula?
nm i just read all of your post.

Sweet! 3mph gain from headers and catback, not bad. The say 1mph = 10rwhp approximately. That means you picked up about 30rwhp with the new exhaust system. Glad it has worked out for ya.
