The Supra, Vette, Viper shot-out was a blast. RSI took FIRST PLACE, great job, TNT showed and took second w/a 600 shot of Nitros. They finally got smart and dumped the Queen snake intake.
Dr. Roof took 3rd over all after a 30 hour drive to make the race. Dr. Roof is a great guy and knows how to show up for a race even if it is 1000+ miles from home. A Great day was had by most even the Supra group. Their was a 8.9 sec. run by the top-Supra during practice.

Albert Chlouber drove my RSI unlimited and with a blown clutch, he still took a 5th over all /images/graemlins/headbang.gif. Albert is one hell of a driver, Cool as Ice when it comes to driving :cheers:.

Gerald and the entire RSI group made an impressive showing.

Anyone wanting RWHP, a reliable motor, Honesty, a stroker or any other quality motor needs to visit the RSI group.
Nothing funny, no block swaps or old motor parts being installed at RSI. The Texas quality Tuner.

I think that their were 4 Vipers in the 9's including Alberts own car.
What a race

I will give some props as they are due:

RSI did a nice job and cars were fast. Rohn's car looked fast even from "a distance".

TNT got some respect for laying down the fastest Viper times of the day.

Albert and Jason Herrera both did a nice job of driving.

Peter Blach had a very good turnout on a nice event, I'm just sorry I didnt get to "stay" longer.

Mark, Norm WYD and Golder did a nice job keeping the pot stirred up. And Scott did a nice job of driving for us.

And Prashant did a nice job of helping the Vipers come together to beat the Supras.

The red car would have given them all fits if it would of lasted. Your merry band is a group, first time I have spoke to them face to face. They had everyone guessing.
When we get the clutch problem fixed I hope to go toe to toe with some of the big dogs.
Later

Ya they are a merry band on a good day. Mark, Golder and Norm "WYD TX" Koerner and their posse have been known to stir the pot a bit. You never know when they might just jump out of the bushes. Sunday at the track was a good example. More fun to come..........

Too bad I missed out.
I didn't have anything fast enough to compete with the big guns yet anyway.

Hey Jason, but you always do well in the off-track festivities.

I couldn't make it either. I had planned to go though. Got a brand new video camera for the event. But I had something come up last minute.

What were some of the other faster Supra times? I know about the 8 but that's all I seem to be hearing about. What about all the other Supra's? Who else ran well?

Thanks for the props, John.
I've been out of the game for a while there too.
Other priorities have overtaken me.
I'll be back in soon, at least with a faster car.

I have a question about HP and Torque for hoking up and getting a fast ET. First, I would like to say that I was always under the impression that the Supras were so quick due to the fact that they did not have massive amounts of torque right off the line which made it easier to hook up==> then once they're rolling the HP kicks in and they are gone. Now, with the Vipers it seems to be the opposite, the ones with the largest amount of low end torque seem to be the only ones in the nines. Look at all the nitrous cars......of course, low end torque. The Hennessey Turbo cars must have different cams and turbos sized to mimick the nitrous power band because the 907 RWHP car on all boost from his website hits peak power from 120-126 MPH which is about 4700-4950 RPM.

Tom Welch made a comment a couple of weeks ago about needing at least 900 RWLBS/FT to go nines.

Whatever happened to "it is always better to have your torque curve relatively higher in the RPM range to take advantage of GEARING"?

What is the scoop? Why do the Supras and Vipers differ so much in how they do the nines?

Paolo,

Without being long winded, a Supra uses a small displacement, high rpm engine, which has a very narrow torque band, hence the car is easy to make work on the dragstrip.

A Viper has a broad and flat high torque band with usually lower horsepower and a very inefficeint chassis, hence making the car difficult to make work on a dragstrip.

My statement of needing 900 RW/TQ to run a 9 is more about chassis efficiency (or lack of it)and the amount of torque required to achieve this goal based upon the remainder of the quarter mile after the first 60 feet. Keep in mind that the first 60' of the quarter mile is where the TOTAL elaspsed time is made, and it takes alot of power and torque to accelerate a poorly launching 3600 LB car into the 9's after the first 60' is wasted.(thats why 142+ MPH is minimum for a HIGH 9 second Viper, but commonplace for a 9.20 prepped drag race chassis car)

Tom, thanks for your response. What you are saying makes a lot of sense. I called those Titan Motorsports people yesterday for the heck of it to see exactly what that car has done to it. They said it has a stock rear end that has a completely locked posi, stock 6-speed tranny and 1155 RWHP. He said they usually get 1.4-1.5 60 footers. I have never really been into the 1/4 mile but all this talk lately has been interesting. I hope my car is done in time for the event in Kentucky. Thanks again.

I have to disagree with Tom on this. The Supra is NOT an easy drag car. If you look at the times they were in the 10's and 11's for the most part, yet the MPH for these cars is well into the typical drag car 8 second range. It doesn't take 900 hp to get into the 9's. It takes a well thought out suspension and tire combination. It takes a smooth delivery of power that is consistent throughout the powerband.

If you compare how many Vipers were in the 140 mph+ range versus how many Supras were, the true indication of RAW power is clear. Had this been a 3/8th's mile track the Supras would ALL smack down on the Vipers. The Nitrous Vipers would have had a new view of a red GTS. Take it to the streets and the truth is the Supras would dominate. No one runs a quarter mile on the Tollroad.

It was a great event... no doubt. TxWYD and Dave sure stir the pot and once again Prashant did his best to satisfy the Emperor and Sheik while making everyone else happy too. I would have liked to see an open street tire class. That would have been interesting to see an outcome.

Cheers,
