Byron 9/26 Sunday

[XfireZ51]

We need some dyno time. Exactly what changes have been made since the 116 trap speeds?

[LGAFF]

No changes

[-=Jeff=-]

Any mods or changes since the last time you ran the better et?

[LGAFF]

Nope, have to wonder how much of it is Gas quality, or other.....changed my oil and thats about it.

Coils are originals.

Injectors are Accels, pumps are only a year or so old. Tires are 1 year old Sumituno's

[-=Jeff=-]

The Weather and the tires would contribute to the slow ET.. cold track, cheap tire and I bet you spun out of the hole.. But even with spinning you should show a better MPH.

Also I thought you had not run with the Lightweight FW, Speaking of did you adjust the tune at all after adding the Fidanza? Even if you tell me that it ran great last year with the Fidanza and no change in tune, was the weather the SAME then as today? The fuel might have been fine for that day last year but not today..

What are you shifting at? using a Tach or Shift light? is your tach Accurate? did you have a Scan tool on the car during the runs to see if there was knock? what was the AFR during the runs? I would be looking at everything before throwing money at it. try to find where the issue is..

I keep telling you guys if you wanna pull your hair or go gray just keep racing at Byron.

I bet with no changes you could run 120 at Byron next week.

Al was gonna be there today did you see him?
Did you see a Supra and a Mercedes CLS65 running 10's well maybe 11's at Byron, both guys names are Marco but Marco in the Mercedes is the Supra Marco had the fastest Supra back in the day 8.50's now he cruises in a 10 second luxury Mercedes.

Al was there I saw the CL65 run 11.3 last year and it eased out of the hole, and let up at the end....scary.

No 441 for AL

Before you drive yourself crazy, you need to plug all your best runs into an altitude density calculator like this one.

Temperature, humidity and air pressure can have significant affects on the results for any given day and location. This will give you a constant basis for comparison by taking away those variables.

Byron LOL

[Pete]

I have been racing for a very long time and have always used US 41 and GLD never in my life have i seen a 4-7 MPH difference that is like 65-100 HP loss

Even now you guys can see my Z run from one day to another i get 128-129 and that is at 3 different tracks.

Lee go to Byron next week you'll run 118.

Lee,can you tell me your 1/8 MPH & ET
