Well to be fair we don't have any info about the track he was running at. The big things like DA, temp, humidity, are all missing from the equation. Trapping 118 he should easily have 11.5-11.8 in the car.

 

Mickey thompson et streets, 305-35-18. Great tires.

Here is the track data:

Sacramento when i trapped 118

Infineon when i trapped 111.7

What's crazy is the da was worse when i was trapping 118.
Everyone i talk to at the track said they loose 2-5 mph compared to other tracks, but the traction there is so much better. I was launching at 2700 compared to 2000 at the other track.
The lasers could be off but infineon is where they are holding the autolite nationals and i find it hard to believe it's that off. Also, when you look at the two slips i am faster at every point through the 1/8th mile than i loose speed throught the finish. THat would make sense when it comes to the wind having a large effect. All i really care about is my et and that is heading in the right direction, faster.

 

The slip with the 118 mph seems a bit unusual. Your 1/8 mph was 90.4, then you do 118.3 mph in the 1/4. 28 mph is a lot to pick up on the big end. I usually make up around 24 mph. On the 111 slip, your 1/8 is 92.5 mph, 2 mph faster than the 118, yet you only picked up 19 on the big end.

Trying to make some sense out of this. 28 mph on the big end seems a little unrealistic, yet 19 on the big end seems a little too low.

 

I guess that is somewhat unrealistic, though I have ran an 11.427 @ 117.54 w/ 1.595 60'. I did think that my trap speed was kind of low on that run though for the ET, seemed a mph slow. (1/8 trap was 95.29, so I only picked up 22.25 on the big end)

 

for a 118 trap I'd think you'd need 91-92 mph or so @ the 1/8, so to trap 118 @ a 90.x 1/8 seems a bit low IMHO based on 2 yrs of slips in my hand.

based on my last trip to the track I avg a increase of 27.1 mph on the big end, with traps in the 119.3-120.0 area

 

Wow, 27 is a nice pick up, I guess that's a centrifugal blower for ya. I average around 24ish on the big end (with a little over 25 being my highest), I'm sure the OP will see a pick up closer to that since he is running a PD blower like me. Makes the 28 mph pick up a little more unusual.

What are the other saleen guys doing on the big end?

 

yeah the motor just keeps making boost and power as the RPMs go up!

IDK about other Saleen guys

 

Sactown ran a 11.92 at 119.7 at the same track i trapped 118 at, i his 60' was 1.72. He has the same set up as i do except he has a cai and put down 20 more hp than me. He is also a better driver than i. As far as building hp, when i looked at my dyno sheets it just continues to build until i redline. My peak hp is right at redline. He is actually coming down to my track in august so i want to see what his car traps.

Side note, would it a be a good idea to mix in some 100 octane while at the track, or does it not really matter since the car is not tuned for it?

 

as far as setups and dyno numbers - 20hp is really not a significant thing to point to. too many other factors as to the #s - what dyno, weather on the day of the pull, what ECT the car was on the pull, what RPM it was pulled to....

not a bad idea to mix in 100, it'll help to avoid any detonation and knock, this will possible prevent the computer from pulling timing if your running on a hot day or not letting the car cool a lot between runs.


anyway... IHMO one more day of seat time as many runs as you can

then - go and really let the car cool and make a few passes for that killer ET

 

oh yeah, my peak HP came at redline too, wish he would have used a couple more rpms so I could have hit 500 even, LOL. It's all in practice, especially when you are pushing a lot of power, its easy to screw up the launch, miss a shift, etc.

Be careful mixing too much 100 octane in your car though, since it is not tuned for it. The energy content per volume in 100 octane is less than 93, so it will cause you to run leaner.
