For all you guys attending SSHS4 you might want to look at this information.

I'll put my money on the s****t p*****t.

First time out in such a large venue, but I believe there has to be something taken into account for karma.

I have that link in my favorites, without doubt I expect the SS's to run faster than last year, but not much faster. They started making their cars go fast almost a decade ago so they are already very close to the limits of what you can get out of the LT-1 small block.

We on the other hand have not even scratched the surface of what can be done to our lil' ol 281. IF half of our strongest players show up, it will actually be a contest, if all we get are mostly stock like last year....well than we better be very consistent in the brackets.....:duel:


PS: If I could place an entry in their page I would rank 240 out of 294.

Did you notice Jorge Parez-whatever's 9.98 in that tub, aluminum bumper or not? He didn't do that with no 281 inches. And it's exactly the point Mad and I were howling about in another thread = cubic inches. Zak's in the 11's and perhaps he's gonna break 10; but with with less than 300 inches? I think it's a streatch. Sooner or later, someone's gonna stuff an FE block, or a Lightning motor in an MM, and we can go from there.:hide:

[Smokie]

Yes Mike, the top 20 ET's on that page; about 17 are strokers. We all have to work with what we have, they start with 350 cubic inches and an iron block, so stroking is a natural, but is not a dirty word.

We have far less displacement and stroking (larger bore) an aluminun block is asking for trouble, we have limitations with deck height that I'm not sure can be overcomed without some major modification to k member or hood.

But 2 years after it's debut our cars are becoming competitive with the SS and as they go out of warranty owners will become more comfortable with mods....I believe technology and hard work will overcome the displacement disadvantage.

Sure, but you therefore cannot rule out the technology of the aftermarket for their cars either. So the technology gap narrows when both cars are modified.

I they pull all the NOS bottles, they'll only be left with 1 or 2 cars. :D That list has ALOT of N2O cars.

Sure, but you therefore cannot rule out the technology of the aftermarket for their cars either. So the technology gap narrows when both cars are modified.I don't see it as a technology advantage because the LT1 engine is old technology. It's a displacement advantage, one that I think can be overcome by the Marauder engine's technology advantage, namely the 32 valve dual overhead cam design. I think there's a lot of room at the upper end of the RPM band for our engine. We are keeping up pretty good with those bigger displacement cars as it is because of the better air flow of our heads and I think we can get to 8,000 rpm or higher on a strip-heavy engine. I wouldn't do this on a street-car because I like the way she performs now, "poor" low end torque and all. (BTW, I had to replace my first set of rears last week, odometer read 6784 mi. Now I get up to the light and I am saying to myself, "I will not do a WOT launch. I will not do a WOT launch. I will not do a WOT launch.)

:awe:Good Lord, man! Did you enter some burnout competitions along the way???
:burnout:

[David Morton]

Three times I put the brakes on to turn 'em over and show some of the guys about the high stall convertor but never enough to make smoke. Generally I have the CD turned up loud listening to "Takin' care of business" or "Born to be wild" so I wasn't aware of how much scrub occured when I did a WOT launch at the light but as I noticed I wasn't going to get anywhere near the mileage some of you guys were getting I turned off the CD and ran the windows down and, yep, this baby hooks up good but there is a good four or five feet of grinding sound on take-off.

Plus it has been summer in Florida and the roads are always hot, even at night.

My local Firestone dealer got me two stock tires, mounted and balanced for 162 + tax. So I'm back where I started.

[BillyGman]

I don't see it as a technology advantage because the LT1 engine is old technology. It's a displacement advantage, one that I think can be overcome by the Marauder engine's technology advantage, namely the 32 valve dual overhead cam design.
That's when both engines are factory stock. But once you start modifying them, the advantage of the bigger displacement is multiplied. The greater level of modification that you get into, the greater the displacement advantage plays a role. If you decide to race against these guys, you'll find out what I mean. Thier cars are .5 to 1.0 second faster given the same level of modifications. It's a good thing for most Marauder guys that hardly any of the Impala SS guys care to spend enough money on their cars to S/C them, because if they did, they would all be in the 11's, and I'm not talking about in the cool 50 degree whether either.

[Joe Walsh]

WOW!! Those Impalas are really hustling...Lots of big cube stroker motors. It makes me want to stuff a Ford Motorsports 600+ Cubic Inch '385' Series V8 under my MM's hood and slap '10.0' badges on the fenders! That would get their attention!
Nahhh... that would be too easy..
I like the challenge of making the 'little' 281 pull 4200 LBs like a freight train!

[BillyGman]

What I don't understand is that they have a breakdown of six racing classes on their list, and yet when they open up their events to other cars, they don't stay w/those same classes one through six. I can understand them not being able to do that in an event that doesn't have a lot of racers, but from what I've heard, there are always many racers in their Atlanta event. So why do they set-up different race classifications when they race other types of cars than they usually break it down to for their events??? Why might that be??? :rolleyes:

[FiveO]

NOS is sometimes very difficult to expect.

Just my guess.

Give a 300 hp car a 100 shot might be different on a 90 degree day than it would be on a 40 degree day....

Much more than a S/C Marauder on days with the same temps.

NOS is very susceptible (sp?) to temp if I recall.....

[FiveO]

And many of those LT1's are NOS'ed at those speeds!

Not all...I'll give them their dues...but many are NOS'ed.

[stumpy]

Hey guys, this is a nice thread! If you like this list I'd be happy to ask the owner if he'll give you a copy of the site for your own use. You'd need someone to host the site and update the times, but I think you'd get a lot out of it.

The purpose of the list is mostly for recognizing personal achievement and sharing information and car setups. From my perspective, the list fosters friendly competition among owners and a way of recognizing personal achievement of fellow enthusiasts. Therefore, to involve as many as possible in the pursuit of records we have multiple classes for each level of engine modification plus and additional class for power adder. The break down for each class is as follows:

Class 1 - Class 2 + power adders
Class 2 - Built motors (must be an LT1, bored or stroked or rebuilt bottom end)
Class 3 - Class 4 + power adders
Class 4 - Heads and Cam (must be an LT1, can have ported heads, bigger valves and cam with a stock bottom end)
Class 5 - Class 6 + power adder
Class 6 - Stock motor (must be an LT1, stock bottom end, stock heads, stock cam, this is the basic Bolt-on class)
Class 7 - Other motors (this class for cars with any non LT1 motor, big blocks, LS1, etc.)

You can highlight a class by clicking on it at the top of the page. You can compare two runs to see what was different or alike. For example, click on class 6 and you'll see that the fastest car in class 6 is #74 (Yours truly). It's quite an honor and it's been a lot of fun talking smack with the other fast bolt on cars that will be vying for the top spot at SSHS4 in Atlanta.

If you consider where you guys are on this list, you're mostly in classes 5 and 6. So, if you look at it this way you'll see that most of your class 5 cars are competing with our class 3 and 4 cars. Where we start pulling away is in class 2 and in class 1 we're much faster. I'd say that for the short time that your cars have been around you're doing damn good. Someone just needs to blow one up so they can stroke and poke it with better cams and a blower. Do that and see how fast it'll move.

As for the blowers on an Impala, there isn't a roots type blower for our cars (yet). Also, the stock bottom end on an LT1 tends to grenade when blown with the hi psi centrifugal blowers. Therefore you have to build the bottom end strong and pray or just keep the pressure down. That's why so many Impala guys have gone with N2O. It's less likely to grenade the motor and you can get so much more out of it than with an expensive low psi blower. A friend of mine in now waiting on his 3rd blown 383 to be installed with the last 2 lasting less than 500 miles each. :depress:

It's quite an honor and it's been a lot of fun talking smack with the other fast bolt on cars that will be vying for the top spot at SSHS4 in Atlanta.This is what I meant in my previous post Glen. You are in class 6 like the majority of the marauder guys here would be (bolt-ons w/stock internals) and you are running 13.0's in the cold whether, and I know that you've even broken into the high 12's on atleast one occasion. The fastest N/A marauder here is Barry (aka "Cruztaker") and in the cold temperatures the best he's acheived are 13.3's. So your car is running about 4 tenths of a second faster than Barry's is, and I believe that barry accomplished that ET with slicks, and he even took out the headlight to get the cold air in his engine which he has claimed a 2 tenths reduction in his ET from doing that alone.

If you consider where you guys are on this list, you're mostly in classes 5 and 6. So, if you look at it this way you'll see that most of your class 5 cars are competing with our class 3 and 4 cars. Where we start pulling away is in class 2 and in class 1 we're much faster. I'd say that for the short time that your cars have been around you're doing damn good. Someone just needs to blow one up so they can stroke and poke it with better cams and a blower. Do that and see how fast it'll move. It looks like our class 5 Marauders are somewhere in the middle of your class 3's and 4's. There are several Impala SS guys in class 3 that are in the high 10's and low to mid 11's. There are many of them in the 12's though. And ofcourse all of the Impala class 4 cars are in the 12's and low 13's.

As for the blowers on an Impala, there isn't a roots type blower for our cars (yet). Also, the stock bottom end on an LT1 tends to grenade when blown with the hi psi centrifugal blowers.

A friend of mine in now waiting on his 3rd blown 383 to be installed with the last 2 lasting less than 500 miles each. :depress:Hmmm, I wasn't aware that there aren't any roots S/Cer kits available for the Impala SS. That's too bad, because it would be interesting to see a number of S/Ced Impala match-ups against S/Ced Marauders, both of which being otherwise stock engines. That would be atleast close to comparing apples to apples I'd say. But as it stands now, in any heads-up racing, if Marauders like mine were to be matched-up against class 4 Impalas, my car would have an advantage, and if my car would be matched-up w/your class 3 cars, your cars would have an advantage. So there can be no apples to apples comparisant heads-up races w/our cars that are S/ced, and any of your cars. :(

The classes listed in the link are for ISSCA events.


SSHS4 is not an ISSCA event so they do not apply. We use bracket times for classes in the shootout.

:cool:
