Looking forward to this class and I'm willing to bet I'm the only M6 car in it! Now that there's plenty of time to make plans who's gonna come run? @joelster (http://ltxtech.com/forums/member.php?u=384), @quik95lt1 (http://ltxtech.com/forums/member.php?u=1930), @Badhawk (http://ltxtech.com/forums/member.php?u=772), @AChotrod (http://ltxtech.com/forums/member.php?u=106), @Nocturnal Z (http://ltxtech.com/forums/member.php?u=240), @Tyler Wheat, gump (http://ltxtech.com/forums/member.php?u=37)

My dad may join you this year in his camaro josh. Just depends on what we do to it this winter. Right now he's teetering on the edge of es and mod

[96LT1355Z28]

Good deal!

[dawdaw]

Well depending on what my car weighs I'm leaning on running this class as a 2nd class to my power adder class. .. When can we register so I can pay ?

Awesome! Should be a great class this year. We will be working on getting preregistration in place soon.

[96LT1355Z28]

Kyle, not sure your car will meet the rules with your NO2 stuff for the PA class. Look at the last line under "Engine & Drivetrain Rules"

[DMBlack]

I think that is one thing we need to look at wording on. Having the bottle out and feed line off/capped should be sufficient if you want to run the n/a class. I will discuss it with the others. firebird_1995 79LT1Monte

[firebird_1995]

Yea I wouldn't bind anyone up on being able to run both classes. For those wanting to run both I see no reason not to allow n20 cars to run in the na class as long as the bottle is removed and an inspection done.

[dawdaw]

Ya that's no problem . If rules state you can't run the class because there's nitrous stuff on the car I won't. .. I just want to run a couple classes but 1 power adder class will be ok ...I was just going to disconnect the bottle was all

I don't think it's going to be a problem kyle. Like David said, bottle removal, capped feed line, and an inspection is going to be sufficient. It's pretty common for nitrous guys to run na classes as well. Not so easy for FI guys lol

[dawdaw]

Take the belt off ;)

Turbos remove them haha

I'll give you a shout later today chris. Need to send that lm1 back. Damn tracks are all shut down now ��

[firebird_1995]

Sounds good. Tending to sick kids now...

[DMBlack]

Updated rules to LS1/24x conversions will have a 100lbs weight penalty.

[96LT1355Z28]

Thanks for the update, looks like a great class!

[Palamino]

Updated rules to LS1/24x conversions will have a 100lbs weight penalty.

Does this also apply to rear mounted distributor conversions? I'm new to this forum, but thinking about bring the race wagon.

Cool wagon! We would definetly like to see it at the shootout. What PCM are you running? A LS1 style PCM with a rear mounted distributor will still have a 100lbs weight penalty. So minimum race weight including driver would be 3200lbs.

Running Carb, 7AL and T400. No computer. Also 3850 pounds so the weight adds are not much concern.

Carbs will have a 200lbs weight penalty, so it would be 3300lbs minimum weight. Yeah, at 3850 I doubt you will have much of a problem meeting minimum weight.

[joelster]

I don't think there is any way to get an Impala down to minimum weight lol!

[SSlowBoat]

Now that's not nice lol

[DMBlack]

It seems that the B-body guys have it figured out though. They are out there hauling the mail with those extra lbs. I hope to see that Roadmaster wagon in Bowling Green.

[firebird_1995]

And that carbed Buick Lasabre! Still looking for that guy...

Poor "step backwards" carbd guys.... [emoji83]

[Chopstix]

Popo why do you keep saying a carb is a step backwards?...do you not understand the benefits it provides over OE PCM?

[popo8]

Cause i keep busting someones stones who said that to me because im going carbd.

[Chopstix]

the step backwards on your car is not the carb ;)...its the intake...but for your application it will be just fine

[BlackWidowSS]

If all goes well this year, I will be able to run this class at the shootout. The hardest part will be getting Labor Day Weekend off of work. And yes, I am an M6 car lol. A few goodies are being installed next week.....ok ok, a TON of goodies... ;)

[popo8]

Noooooooo...my balls were busted over the "step backwards" being the carb and the fact that Im not using the entire set (computer/harness/Fuel injection/etc) up from the donor car..... It was NOT about the intake.

[96LT1355Z28]

BlackWidowSS, it'd be sweet to get to line up with another M6 car!

[JCzNova]

I know of another M6 car that will be there. \/ \/ \/

[96LT1355Z28]

Good deal! I'm thinking of playing with some different blends of race fuel this year, but I noticed the rules state "gasoline or E85 only". I've never messed with race fuel before is it considered gasoline far as rules go?

Yes. Race gasoline or e85 is allowed in this class.

[96LT1355Z28]

Pretty quiet in here, any details from anyone? I'm changing exhaust, front tires, and gonna play with some more tuning. After talking to several other local racers the cost of race gas probably isn't going to net me a big enough gain to justify the added cost. Really looking into a vacuum pump but I'm not sure it's gonna happen this season. I'm still paying for the big chunk I bit off last year!

[dawdaw]

secret squirrel stuff
josh?

if you would like to.run a moroso vacuum pump let me know and i will send you my.bracket so you.dont have to screw with trying to make one.
... i think you will net some good results with one, and even.better results when you run an appropriate ring package with a low tension oil ring

im ditching a few lbs to try and get around maybe 3200lbs maybe 3100 if money allows, and switching over to a super super oxygenated race gas versus the e85 stuff i was running, shouldn't go much faster but will be a lot more consistent . some mid 6.50s on motor are my goals.
:beer:

[dawdaw]

josh if your running 93, you will pick up a solid 10 hp if not more running a highly oxygenated race gas if tuned properly, shoot me a pm

[96LT1355Z28]

Yea, VP told me to use MS109 (unleaded oxygenated), but I can get VP113 (leaded oxygenated) locally for a decent price. Just not sure if 10HP is worth the cost per gallon over the ethanol free 91 I'm using now! I think I'm better off doing some more work on the tuning and adding a vacuum pump. Not sure if I want to go with the Moroso like you have or with the GZ Sportsman like Mike V. I might take you up on the bracket though, I'm gonna need one for sure next year if not late this year. quik95lt1, how are you liking your vacuum pump?

I'm at 3380 (w/ driver) now and my weight for the calss is 3300 with my Holley EFI. I'm just gonna loose a little more weight by switching the metric radials up front for drag fronts. I'd like to cut out my MS S&W 8pt roll bar and do a 10pt CM cage but I'm thinking that's gonna be a wash as far as weight goes. That;'s a project for when we get a bigger house and bigger garage!

[dawdaw]

ya... i dont know how your conputer works but maybe you could have 2 tunes. let me know on the bracket

[96LT1355Z28]

I can store as many tunes I want on the laptop!

[dawdaw]

:) so can i with my rusty stock computer .


vacuum pumps rock!

[Badhawk]

I'm in just not of changes yet if any. I might just run it the way it is and make some changes next year. I wish someone close had an engine dyno I want to play with a couple of single planes and see what happens.

Modified N/A
Engine & Drivetrain Rules

Aftermarket EFI PCM and Carburetors are allowed with a 200lbs weight penalty. LS1/24x PCM conversions allowed with 100lbs weight penalty.

Sorry guys, but this is a dumb rule. What is the basis for the 200 lb penalty? Or any penalty?

[DMBlack]

I understand where you are coming with this, but we went with a weight penalty to give the nod to the guys still staying with the LT1 PCM and Opti. The advantages with the aftermarket EFI is pretty significant of the stock computer. It came down to a weight penalty for aftermarket stuff or a weight break for guys still running LT1 PCM and Opti. The only reason we have this event is because people have pushed the limits of the factory stuff and we think guys still getting it done with the Opti should have the break.

[firebird_1995]

There was quite a bit of disagreement about the use of aftermarket and 24x conversions, especially in this class, however the basis was that anything other than the stock pcm had an advantage and it was put in place to try and level the playing fields for the guys that still run an opti. We are inviting EVERYONE to join us after the award ceremony to hash out what is best for the community as a whole so we can get car count up and make as many people happy as possible. I can assure you that we will address every concern

Darren, Are you bringing GUMP this year? Everyone's favorite stock eliminator lt1 ! I love watching that car run

[96LT1355Z28]

X2 for wanting to see Gump on the starting line again!

[gump]

Gump went into retirement after the 2013 Shootout. I have had a lot of fun running with you guys. There is still a bunch of good LTX stuff in my shop, so you never know what the future holds.....

You really think that the advantage is that much? Or is this just a crutch for the guys without much of a combination?

Understood. I am just not much for the notion of taking one in the name of car count for the privilege of requesting a "level playfield" next time.

[Badhawk]

We will keep our fingers crossed. Love to see you bring something to race Gump will be hard to replace though.

Dang. build a nasty naturally aspirated set up Darren. No stock nothing! If my drunk memory serves me right, you and Mike v are 2 and 2 tied. ... gonna need to drag some of those good parts off the shelf

What are you doing with gump?

Do you still have the stock internals lt1 you built years ago with those kids?

[firebird_1995]

You really think that the advantage is that much? Or is this just a crutch for the guys without much of a combination?


Personally, no. I do not see it as that much of an advantage. I also think that the majority of cars in the modified class are not running an opti anyway.

What does car "retirement" consist of? Is the car still "whole?"

[gump]

What does car "retirement" consist of? Is the car still "whole?"

Gump is one that I will never part with. I ordered that car new in 1995. Turns out it's a one-of-one! Only 000186 original miles too!! Retirement consists of a few cosmetic fixes, new tires, new decals, and a show car sign.

I still have the kids stock internals car. It now has a blueprinted LT1 and should see a little track action soon with my buddy Rodger driving.

If I were going to run the Shootout, I would bring the car that I have been threatening to build for years now. I really have a lot of projects going on. I am converting my red Formula to run Chevrolet Performance Stock with the NMCA. We will be racing both COPOs in Stock at a bunch of NHRA races. I also have two body-in-white Camaros that I am building to run in Stock later this year.

I would love to have another shot at Mike. I just don't think that my litle 345 ci LTX would be very good at 3300lbs.

I understand what you mean. Unfortunately the only way we can prove or disprove if a certain modification has an advantage over another is by pitting the 2 against each other.
