I'm sure a few menbers here have taken thir SSR up to top speed, but has anybody reporgramed the ECU to remove the top speed limit? Anybody know the Frontal Area? Drag coefficient?
I currently run a Mini Pickup at Bonneville and am working on a land speed record. The major limiting factor is aerodynamics. I assume that the SSR has much better aerodynamics than any other small pickup, but what is it exactly? although the best information would come from a wind tunnel, I found a link where you can determine the drag by measuring the coast down of the vehicle. Follow this link Measure the drag coefficient of your car
The current record for a pickup with a 6.0L engine is 210.473 mph and was set in 2006. the guy had a Chevy luv truck with a V8 stuffed in it. This was in a modified class because Luv trucks never came with 6.0L engines. The record in the Production class where the SSR would run is only (ONLY)201.014mph.
So what do you guys think? Is it possible to get an SSR up to 211mph?
My SSR: "Rev'in Mr. Black" 1995 Impala SS - black with a 383 stroker motor
I have removed the speed limiter on my ECU and have had my R to 143 mph on the GPS it was still pulling pretty good but if I recall RPM was around 4000 I don't think with the 3.73 rear it would have the power to push past 175 mph but that is strictly my opinion. I will be interested to see what you can do. Good Luck

Hmmm, I think over 200mph is "top up" time!

Rats, I was so sure you would be telling LandSpeed he would have to better Hellvis' 215mph! Jeez, 163 mph. I think I would want to be on something wider than a road, like Bonneville perhaps!

Don't know what the rules are in Production class but I think you can do it .. but not with stock wheel & tires as they are too wide.
On a side note Peter ... do you know Land Speed Louise? (Louise Ann Noeth) She an old friend of mine & is she involved in Land Speed stuff. Personally, I haven't seen her in several years.

To be fair, I wasn't the only idiot.....
My good friend Mike in AZ was side by side with me.
We both run Z rated tires, and all I thought about at that time was tire failure.
Do NOT try this without Z rated tires, unless you have a death wish.

Production class does let you run any wheels and tires you want if they are rated for the speed you are going, over 200 you generally run Goodyear land Speed tires that are rated for 300mph.
On a side note, i have not had the pleasure of meeting Speed Louise, but i will keep my eyes open for her.
Peter, Do the rules allow any body mods in the Production Class?
The only modifications allowed are lowering and a hood scoop. the whole idea of a production class is to run a car you would see on the street. You do need a roll cage, fire system, race seat, 5 point harness, fire suit etc.
At Maxton NC (Maxton Mile) you can run up to 130 in the standing mile with just a helmet. 155 with just a roll cage and a helmet, over 155 you need a fire suit. But it is just a 1 mile run from a standing start. These are called "real Street" Classes. I believe at Bonneville in october the have a similar event where you can run your street car on the flats, same thing though, standing mile.
I compete in a Flying mile where your speed is measured over a full mile. It is a 5 mile or 7 mile course, less than 175 you use the 5 mile course and your speed is timed on mile 2 and mile 3, you have 2 miles to stop. Over 175 your speed is measured on miles 2,3,4,5, and then again you have 2 miles to slow down.

Hard to imagine reaching those kinds of speeds with the front end area of an SSR, even with some modifications including supercharger. Eliminating ECU top speed limitations won't make much difference.
Last tests I saw on a stock ZR-1 had it creeping up on 199 MPH - on a comparison run on Speed RV.
The ZR-1 has a whole bunch less frontal area, and a whole bunch more horsepower than a stock SSR, pushing about 1400 lbs less weight.
That 163 MPH run Doug took Hellvis on definitely confirms one thing. That boy has way bigger balls than I do.

Land Speed, you do realize you're talking about a 4800# ride?! If you can't modify the engine at all, there isn't a prayer. I don't think a stock LS2 Vette will reach 2 bills @ 1000# less weight and way better C/D. A cowl scoop would probably be a huge help as the air inlet, in factory position is real poor. Good Luck!

What pickup set the Production class record run of 201.014 mph ?
Land Speed, you do realize you're talking about a 4800# ride?!
Bonneville cars need that kind of weight partly to get the power to the rear wheels as they're not using drag slicks.
Remember, this isn't a quarter mile run. Totally different set up.

You mentioned Mike was right alongside you. I don't know anything about his SSR but wouldn't have thought he was running near your amount of hp, or is he?

Look at it this way Cash ...
Mike got the engineering skills for speed and Doug got the wallet for speed.

I never said you couldn't modify the engine, just the body. You can do anything yopu want to the engine so long as you maintain the displacment and the block deck height. You are allowed to use engines from the same family, and even aftermarket blocks. The only rule is the deck height. If you use a supercharger you move to a blown class, to to stay in production you need to stick with a NA motor. Many people in the 6L class are running Nascar motors without the restrictor plates. I would think you could get in the 750 hp area pretty easy.
The weight is not really an issue, this is not a drag race. I added 500lbs of ballast to my current truck and am probably around 4,000 lbs. The limiting factors to top speed are rolling resistance and air drag. More weight will increase rolling resistance, but the wind resistance is a much bigger factor.
What pickup set the Production class record run of 201.014 mph ?
The record books do not state the make and model of the vehicle that set the record. But the only small pickup truck that came with a factory V8 was the Dodge Dakota. Since you have to run aversion of the engine that came in the truck, my guess is that they ran a dodge 5.9 or the Nascar version of that engine.

With 600 at the wheels, my Jeep Comanche would be able to go 200 mph or so. 600 at the wheels would assume 750 or more engine hp. Does that seem like a correct number to you?

I'm not an expert, but I believe it's less about HP and more about gearing and fuel availability and efficiency, weight and aerodynamics.

It takes a specific amount of HP to make maintain a vehicle at a specific speed. 3 basic factors work into this, Drag (Areodynamics), Rolling resistance , and drivetrain losses. You notice i used the word maintain, acceleration requires additional hp. So if i need 300hp to maintain 160mph, and i only have 300hp available, then as i approach 160, most of the hp will be used to overcome drag and rolling resistance and very little will be left for acceleration.
Gearing is important, the HP output from an engine is not a constant, it is a curve. The HP required to achieve a speed is also a curve, where the 2 cross is your top speed. At Bonneville we went 155mph and the engine was @ 5200 rpm. the peak hp was at 6000, but because the gear was not low enough the curves crossed too soon and the car ran out of HP. If we remove the 3.08 gear and install a 3.55 the car will go about 165. This is why quick change rearends are popular in racing.

I have a friend in Gilbert AZ. that use to have the speed record for class C sport cars at Bonneville at 223.051 MPH in a class stock 1985 Corvette. Someone beat that record at over 230mph, so now Ed is building up a new engin and try for over 240 mph.
