Well I finally got out to the track tonight for my first time. I was pretty nervous so my first runs were crappy...but I ended up with...

Best run
R/T:1.083
60 Ft:1.764
Trap:86.2
E/T:7.916

Mods-TBE,MBC and jestr tune...This was done on pump gas spiking about 24 psi...

What do you guys think? I know my 60ft can improve a bit more...Any ideas what I will run in the 1/4 mile?

 

That would likely be a 12.4-12.5 @ 110 or so. Driving was good - power is low for a IX.

 

^wow really?? I made 332whp, 330tq on a dyno jet...I guess its times for meth and cams...

 

Or perhaps a weak clutch. your "low power" IX will give him a run for his life as is.

 

Huh? I ran 7.9s @ 86 with a cat-back/mbc/safc on my VIII with less than 300whp. Not sure how he'd give me a run for my life when I make lot more power than that now. Regardless, that's hardly important. IXs make a lot more power than VIIIs on stg1 mods, but his isn't, so I'm letting him know that.

MR06Evo, when I say "power," I'm not referring to your dyno reading. All too often, people get their dyno number and are happy, but then it doesn't show up at the track. The problem here is that 1/8th mile is basically useless. For all we know, you might pick up 27mph on the back-half and hit 12.2 @ 113. We can't assume that will happen, so we can only make a guesstimate based off your 1/8th, which indicates much less than 330whp.

 

Are you shifting to 4th in the 1/8th? If so that can hurt your MPH some.

 

Yea I am like right at the end....

 

Try running out third. It's ok to let it tap the rev limiter right at the line, but I wouldn't stay on it.

 

Good question. This is another reason why I consider 1/8th mile tracks worthless other than for launch practice.

The way they measure the traps is different (usually) than at a 1/4-mile, and you have to worry about staying in 3rd or shifting to 4th. On a 1/4-mile, you don't even think twice...you just shift to 4th when it's proper without worrying about it, and then your final ET/MPH show the full ability of the car, whereas the 1/8th may appear weak or strong depending on the powerband and shift points. Analyzing times from an 1/8th-mile track can be misleading, and hopefully they are in this case.

 

^yea because I thought I was were I was suppose to be power wise...Don't most 9's make 330whp and 330tq with basic mods???I had a good time though and you're right my launches kept getting better so it great practice...I want to make it out to the 1/4 mile track but its 2 hours from my house....

 

Yes, your dyno numbers are directly in line with your mods, but the dyno doesn't always tell the whole story. The track is the great equalizer.
