I get the frequent flyer discount... LOL!

As Fazm mentioned I try to be fair and honest... I had a slightly modded V6 Mustang... Think I had over a 100 pulls on it a 2 year period... My old website is still up... guess I might have to start updating it again! LOL! (it's www.v6john.com)

What RPM are you launching at?

Right around 2000.. maybe more like 1800.... I actually found I was getting better 60's leaving the TC on...

What RPM were your shifts?

Car is shifting just before or at redline... I haven't actually datalogged it yet... The shifts are a bit soft and slow... but there are only 2 of them! LOL! Going through that traps in 3rd gear about 5400 RPM... so could use a little more gear in the back or maybe a bit smaller (and lighter!) tire.... But don't seen either of those happening.... LOL

Ok... here is the dyno sheet... Today was very different than last Saturday... Unfortunately I don't have the luxury of doing a baseline, do the mod while the car is still on the dyno and then doing another pull... Ok, i guess if I was testing out a K&N filter I could do that! LOL!

That being said... It does appear the DynoJet is doing it's best to apply the SAE correction factors... Unfortunately I don't have a portable weather station to verify the DynoJet is using the right temp, barometric pressure and the vapor pressure... again... this simply me trying to be fair and honest... This comes out of my own pocket... just for my own satisfaction... so basically it is what it is...

Here's the sheet comparing before and after...

Graphs are almost identical except for around 5100 RPM where the new exhaust picks up some HP/TQ. In some spots it looks like it could be in the 8 to 10 RWHP/TQ range... Not a tremendous amount but it does seem to show up...

closer look at the gain:

So.... bottom line... slight performance gain, improved sound, reduced weight and looks a LOT better!!!! LOL!

Tomorrow I hope to make it back to the track that I ran at last Saturday... hopefully weather conditions will be similar! LOL!

PieNsky · 07-11-2009, 07:06 PM

Yeah, I thought you would be shifting near 6500-7000 per the torque/hp curve. Cool that you are taking the time to put this up.

MadMaxx · 07-11-2009, 07:17 PM

Grats... I wasn't too far off on the muffler weight LOL

Still waiting on exhaust info. What make and what exactly did you change?

Ok... I'm taking the dashhawk to the track today and will do some datalogging...

Right now I have it set to log:

RPM
SPEED
IAT
SPARK ADV
LOAD

Should be interesting!
