What happened to the car that laid down 1031 RWHP and 1052 RWTQ? I have anxiously been awaiting the results for that car. I know it was hot, but air-water intercoolers full of ice are probably the best weapon against less than ideal conditions.

Looks like Hennessey and Heffner were smart to get some cars done and wait for some better weather!

What ET and MPH did Dr Roof's DLM Supercharger car run? Somebody mentioned his car had a technical problem....Was that the blower or turbo car?

Not sure if you are slamming someone or not, but I have to give kudos to anyone that will make the trip......good racing weather or bad. The punks are the ones that were not there, this includes myself.

Tony, I am not slamming! Hey, if my car was done and ready I would have been there! I worked on my car until 4:30 am!

There was big-time hype about this car and all I have heard is hearsay from people other than the owners of the car.

The race was last night, I would have thought I would have heard something one way or another by now. In my mind, it should not be embarassing at all if the car did not meet expectations due to the fact that a 6-speed and clutch would most likely not be working too well under that kind of power. Not to mention a new twin turbo system could possibly need a few trips to the strip and some tweaking to maximize the true potential of the setup. But instead of speculating and second hand information, I would like to hear it from the horse's mouth!

I heard that the car ran a 9.8x on friday. I have not heard anything about yesterday. I also heard that SW was driving it. I wonder what roof ran when driving it.

I think any nine second pass there with the conditions was very good.

I would also be interested to know what roofs dlm car ran. In BG I think it ran a best 9.8x but he ran 147-148mph multiple times, telling me that he had a hard time hooking up.

did rohn say that it was or wasnt roofs car? has roof said it was his car or is it still speculation. moundir said he might buy it and it doesnt seem like roof to have the car built to sell it. am i the only one confused?

I do not know of any BIG TIME HYPE other than others placing doubt. This is exactly why RSI builds great cars and does not post because many like vultures waiting to pick some bones.

The car ran great, flawless other than the pressure plate and that was not a RSI build.
The car in the HEAT (had no choice if it was to make any pass) ran a 9.8 and this TT has zero nitrous.
Everyone that did show up thought it was a great build and in different weather will run a 9.6 or better with no nitrous.

elevation 2000 above sea level, temp 85 to 90.
what if any would elevation do to the times and speeds. All of us noticed that speeds were down.

It should be at Ohio and if you pull into the lane I am sure that your wish will come true. Who knows by them it might run both boost only with a option nitrous.
About Boost, they tried several as this was the Maiden voyage, shakedown and very impressive. SW drove the car except the one or 2 times that David drove it. David was impressed and asked SW to continue driving until he got use to the POWER.
The TT is on its way back to Houston for some final tuning, minor adjustments and pressure plate.
What impressed me is that the TT sounded stock until you took off down the track.

I'll be there. No NOS for me(S/C only)

Don't want to make a big deal out of it, just want to have some fun...

What were the exact times ? 60',1/8 mph,1/4 mph and exact ET ?

I was at the track on a 85 degree day last week that wasn't prepped. Went 9.88 @148mph. These cars are tough when the track isn't prepped correctly.

How is the track at Ohio ? Do they prep it well ? Can we pay extra for more VHT ?

You are saying volumes, thats the way is needs to be, all about a great time, win or loose.
Dr. Rood should be able to answer the track questions, if I talk to him I will ask. I will get back with the 60', 1/8th and actual qtr. Looking forward to a great next race.

One of our better races came when Nick from RSI was going 85+ as he flew by the local highway patrol around 3am on the way back from the casino. Nick knew that he was busted, pulled over and was at a full stop before the cop hit his lights.
Hope to see you at the next.

I'm interested in what happened to that RSI car which made 12xxrwhp on low boost at TX9 if that is the correct name of the event, the Supra show (can't remember exact name). I'm sure houstonT can shed some light on this.

Wasn't SVSi running at the event this weekend?

Sorry for the post hijack Paolo...

It's all about a good time. I really want to have the fastest 6speed S/C car at Ohio, but if I get whipped by someone it's all good. No cryin from me, no shit talking either.

Would love to have a little SC/Turbo clash also.

Any roll-ons on the street while you were there ?

Have you been to Ohio ?

Can't wait to hang out and race with you guys.

RSI Viper at the Supra event was not there, customer was working or not interested. Neither the auto trans nor Jason Styles SC Viper that has ran in the 9.5's before. SVS was not there either.

I give a lot of credit to all of you guys that put up!
Please help me understand something..... I thought Roof's RSI TT car had an air / water intercooler? Wouldn't that be much less prone to heat and track deficiencies in regard to the et or mph spectrum???? I would think that a poorly prepped track would not help et's but the mph would fair well with the air / water IC?

Gerald, for the first time in a while, I agree with you on something. With the air-water IC and a reservoir full of ice water, the intake charge should be just as cool as an air-air on a cooler day. I would think it would not last as long before the ice melts on a warmer day. All other things being equal, I think the MPH should have been way up there regardless as long as they were running the same boost level they did on the dyno. Maybe, since this was a shakedown run, they opted to run less boost.

Rohn if you are referring to me as a vulture waiting to pick bones, you are mistaken. If I am taking your post the wrong way, then I apologize.

Back to business and why I made this post. I was very excited about the dyno sheet from this car as it is more like the power curve I envisioned for my car with the bigger turbos. What a great mother f'er of a curve that thing made: 1000+ RWTQ @4500 RPM and 1000+ RWHP @ 5900-6000 RPM. For going through the gears in a 6-speed, it really does not get any better than that for a power curve as you really never get below 4500 RPM [email protected] 6,000 RPM.

So, whether there was any hype by RSI or not, there was big-time hype in my mind and I wanted to know how it went.

You mentioned elevation in respect to ET and MPH. For all the non-turbo cars, I am sure they were down on power... But a turbo car has the advantage here due to the fact that the wastegate does not care or know the difference between higher or lower elevations: At higher elevations where the air is thinner, the turbo must spin a little faster to generate the target boost pressure with thinner air. Yes, the marginal efficiency of the turbo is slightly less having to spin faster, but the loss due to this is far less than say a blower or NA car that is simply sucking in thinner air. THe NA car is shit out of luck, the blower car could put on a smaller pulley to equal the boost level it had at the lower elevation. But the turbo car, ahh, has to do nothing except for possibly adjusting the tune slightly for the thinner air if there is not an elevation correction factor built into the ECU.

So, like I said, the air water IC(with ice) combined with the properties of the turbocharging should have yielded some big time MPH with 1031 RWHP/1050 RWTQ. I would guess they were running less boost than they were at the dyno. My .02.
