On the other end of the scale, I've run a best of 11.8 @ 122.0 on skinnies & ET streets, and my car makes a twice-dyno-verified 515 RWHP and 525 RWTQ. I know why the ET was so bad (no water box, no VHT prep == 1.83 60') but the MPH I ran is waaaay off what others with similar setups quoted here are running. Unless everyone's running their best times in 45-degree weather with a strong tailwind, I'm doing something wrong. Perhaps someone can offer a pointer or two? FWIW, my power peak is at 5,700 RPM and TQ peak is at 4,500 RPM.
Prep: Set rear tire pressure @ 17 psi (hot) as tire is not screwed to rims. Front tire pressure @ 34 psi (cold) per limit on sidewall. Spare in trunk. Full tank of 92 octane CA gas.
Launch: warm up tires (when possible), rev to 4500, hold car on line with clutch, dump clutch at last yellow.
1-2 shift: 5,800 rpm, lift-throttle, engage clutch over .25 sec.
2-3 shift: 5,800 rpm, lift-throttle, engage clutch as quickly as possible
3-4 shift: 5,700 rpm, otherwise same as 2-3 shift.

Ben, Im making a little more power than you, but not much.Around 550. I drop the rears to 13 pounds. the fronts are at 40. Launch the car at 4000. I shift about the same rpm as you, not speed shifting but I hit the gears pretty fast. Do you have any videos of your car? I will post the slip tomorrow and we can compare. talk with you later.

Just noticed something else. I dont have a rear tire in the trunk and always run at the track with less than a quarter of a tank. Gas is 8 pounds per gallon.

Doug, is there anything you want to comment on that?

Don, LOL, we'll leave the guns and ropes at home. We just want some good racing and competition. Getting beat is ok, but smack talkers that talk about their buddys sisters brothers cousins car *****.

I know I'm not involved in this and never will be, but why do people make such a great deal over E.T. when everyone talks about HP? MPH is HP. E.T. is your ability to hook hard at the track.
Just my stupid opinion, and I'll keep the rest of them to myself

Gerald, I agree to some level. I want both ET and MPH. True if you have the MPH like Doug you are deadly from a roll, If he ever gets it to the ground were in big trouble. I would love to see his car in action with a few supras here in Houston. But until then I guess im stuck in the middle. I sure would like to drive one of his cars around to see the difference.

I can't make TX, however, I would figure on bringing the guns, rope, and by all means lots of BEER! (There's nothing like sucking down a cold one while shooting yer gun off out the window while driving! HE!!, That's a perfect way to cheer one's self up!)
I mean folks, that's what makes TX great and a reason I would like to live there. Now wouldn't y'all!
You have to watch out for those lonesome cowgirls though......

Albert,
Are you saying that there are Supra's in Houston that can out run you? And are close to Doug in Trap Speed? I have yet to run into anything like that here in Atlanta.
I have a tough time imagining a 150MPH Street Supra. I am sure it can be done though.....

Perhaps this will help your imagination
Powerhouse Racing Supra
1250 RWHP + 1.35sec 60' = sub-9s @ 150+. With enough money, you can make a 3.3L engine go very very fast...

I have to say on this one John may have the lead.On my hand how bout John and Albert represent the viper at the Salt Flats(or whatever name that is and were the Jet cars go(spirt of america etc.))and drive as fast as they want in a viper competion.John can take the 800 tt and albert can choose what viper he will drive.

This Supra thing brings a Whole Other Issue....
There are some extremely big mph's being generated by the turbocharged import mini-mites.
While these cars are usually quite lighter (hondas), they generate more HP per cubic inch than even the small blocks.
However, they run boosts from 24 to 40 psi (and more perhaps) (I think F1 can run close to 60 - however, I may be talking thru my hat [have ruined a lot of hats....]
And of course, why is this happening? What is the problem with the big engine cars?
There may be a limitation imposed on normally aspirated computer controlled engines that have to pass emissions - and that is the restruction of wild cams. Big cams are necessary to make megga NA HP.
So that puts us back in the camp of Turbocharted computer controlled engines. Here the cams are relatively mild and do not upset computer control too much.
So that may be the reason there don't seem to be any Big MPH Vipers out there on engine. ....or any other car for that matter, however I think LS1's are getting to the 130 mph level on engine. Still, with the additional cubes in a small block config (better for HP than BB config) the Viper seems lagging.
Don't get me wrong, I claim nothing about me or my cars - this is just a bench racing observation. And I would just love the Vipers to be on the top of the heap!
