Looking for some racing advice.

[DarrenX33]

Great advice guys. Thanks alot. We'll see what happens this year...

Rob,
No doubt that dialing in or tuning the Combo, what ever it may be is the way to go and it is not just one or the other.

The tune/set up you, Pete, JJ ect have on your Big Block cars is amazing. Take any of your cars with the same drivers add some racing slicks and adjust the driving technique for the initial added traction and what are you going to get?

IMO, a lower ET and maybe even a higher MPH. That is the point I was trying to make. Darren's car/combo can over power the tires he has half way down the track, in the current state of tune.

The National Super Stock SS/DA Record in 1969 was 11.40. Your certified stock cars could probably run very close to that today with sticky tires and traction bars.

10-4, Stefano...it would be interesting to just hang a set of slicks on it and see what happens...but I'd say D *might* wanna take some of the slack outta those slappers first! LOL!!

Do you happen to know what the MPH record was for SS/DA in '69?

[Salvatore]

No one really wanted to set the SS/DA ET record for 1969. Was a minimum of 11.27 most of the year. The MPH was at 124.65 set by Dave Wren and his Mopar on 7-69. SS/E MPH record was Ed Hedrick in his Yenko at 125.69.

[Stefano]

Herbie's Hugger/Barry Desalve set 5 track records in 1969 for low E.T., all under the 11:40, but choose not to apply for the record since he was " only racing against himself ".

They also set the NHRA MPH National record in August 19h of 1972 at 126.58.

Sam was probably there!

Darren, The single and simplest inprovment you could make for now is tires (slicks). A 105mph should be turning about 13.2 with decent traction. My prediction is that if you use slicks and reach a 13.2, you're mph will be 106.
After that, it's time to change the rear gears. A 105mph the way it is, and the way you're driving it, means the 12s are easily in reach. (but you'll have to gear it so you're using <u>all</u> of the motor)

[SmallHurst]

I am running 13.20's at 103. What am I doing wrong? 105's should be getting him into the 12's.

[Verne_Frantz]

There's no set rule to figure MPH from ET. There are a lot of variables. Generally, it's horsepower that will give you MPH. If the motor is revved past it's HP peak in the gears, it will slow down. If you're not geared to cross the end at your rpm where peak HP is, then mph will suffer, even if the ET is good. ET is "mostly" made up from how good your 60' is.
33 years ago, my '62 ran a 107 with a 13.15et. But with worse tires (period Casler cheaters) it ran 104 but with a 14.45et! The difference was being able to leave at 4800 rather than 2500. The car still made the same HP after it got going, and the small difference in MPH was because it crossed the line about 500rpm lower than before. (I was further down the track when I shifted to 2nd because of starting at a lower rpm.)

Darren,

You know you could count on me for some help!

Park your car......give me some notice...and I'll strap you into my Lumina Z34 for some real 60' times! lololololol

Here's an 8.30 shot @ 167 mph......



Any questions?
