Ran 11.44 @117.69mph
 

Ran a 11.44 @ 117.69mph last night at the street legal drags, allmost got kicked off for no roll bar, but they ended up letting me run if I slowed it down.

:cong: What, no video? :D

Re: Ran 11.44 @117.69mph
 

slow down??? NEVER!!! Nice pass!

Wife and kids got me a Sony hard drive camcorder for father's day, but it didn't come in yet.:(

Re: Ran 11.44 @117.69mph
 

that is awsome...and street legal too!

Re: Ran 11.44 @117.69mph
 

Way to go!!!

Jim

Re: Ran 11.44 @117.69mph
 

Now to figure out a hidden roll bar.I read a mag article about a guy who went and ran all evening long at low 12's then on his last pass blew it out and ran like an 11.65.
BTW great run! What was your 60'?

Re: Ran 11.44 @117.69mph
 

I am extrememly curious. just how do you get the traction to dip into the 11's?

Re: Ran 11.44 @117.69mph
 

60' was 1.68, at the street legals they don't prep the track any, we waited 1.5hrs. to dry the track after a thunder storm went through just before we started.

My truck is 4-linked, I run 14.5x29 Hoosier QT Pros, My battery box is in the back, and a 20 gal fuel cell that I keep full.

Re: Ran 11.44 @117.69mph
 

Do you have any pics of the four link setup?????

Re: Ran 11.44 @117.69mph
 

That's an awesome 60' for a truck.Maybe you need to smooth your tailgate with lead to get alittle more traction.The 4 link must be working well.

Re: Ran 11.44 @117.69mph
 

I can't remember , do you run a tonneau cover ? Or no cover no tailgate ?
Somewhere i had pics of a '72 running at Seattle with an awesome rollbar setup . He had a Lexan rear window with cutouts for the bar. Very clean set up . Anyway nice pass . :) :)

Re: Ran 11.44 @117.69mph
 

Ya I run a cover, my rollbar is going to come out my back window, I have a slider and the guy that's doing it is going to bring it out the corners. He just did one, and cuts the holes, feeds the bar through then welds it up. I'll have it run through my cover also.

Re: Ran 11.44 @117.69mph
 

There's a few pics in this post.

Re: Ran 11.44 @117.69mph
 

It was one of my better ones, every points race this year at the drag strip I run at has been rained out. So I haven't run this motor combo on a traction compound prepped track yet. I know that it folds my passenger side floormat in half, and I had to rig my ashtray so it doesn't open.

Re: Ran 11.44 @117.69mph
 

nice pass.. why wont they let you run any faster without a cage.. nhra alows for up to 10.01 secound runs.. by the way whats your truck way in at? just curious cause i am building my own drag truck.. here some pictures..

Re: Ran 11.44 @117.69mph
 

I don't even have a roll bar, so 11.50 is as fast as I can run, I'll be running in the 10's as soon as it's in. I keep wanting to weigh it, but haven't got around to it yet. Hope to do it this week, you have any pics of where your cage ties into your frame?

Re: Ran 11.44 @117.69mph
 

what kind of hp you laying down, im building a version of yours only im running a 9.5.1 com 496 roller motor. it should lay down 650 hp and have good steet manners. i don't like just going fast at the track i can't stand to get beet so i wanna have the stuff when ever i need it track or town, its no fun having a bad a$$ truck if you can't show it off every day.. don't get me wrong i love drag cars but im amazed at these 8 sec rockets putting around just wating to bust your you know what when you pass them on the way to wal-mart:) . a 200 shot should keep things even if i wan't to play a little at the track.. im thinking about a roll bar too but it shure would look ugly and give away the sleeper feel too.

Re: Ran 11.44 @117.69mph
 

Who sanctions your local track ? We're AHRA here in Spokane . I don't think there's many ahra tracks left . My mostly stock 68 runs 14.40's , it went almost 3 / 10th's quicker with the tailgate off . It needs to go on a diet as it weighs nearly 4000 lb. Oh well , any racing is good racing . :lol:

Re: Ran 11.44 @117.69mph
 

buy the way a buddy of mine had the trailing arm set up and went to the 4 link he gained one tenth but lost all of his ride and manners. so if you already got trailing arms i would say keep them. however if you got leafs by all means get the 4 link. most all racers will agree that the trailing arms are the best set up thats why nascar still uses them. drag cars may gain slightly with a link set up but if your running a street truck i would think you would kick your self hard if you ditched the trailing arms...

Re: Ran 11.44 @117.69mph
 

here is an idea make a light aluminum or steel frame to fit wher your tailgate was and then order a skin to rivit or weld to it looks the part but much lighter...

Re: Ran 11.44 @117.69mph
 

What do y'all run for a front end , tubular a-arms ? Or ? Lots of weight savings there . :)
Sorry not meaning to hi-jack, just curious :lol:

Re: Ran 11.44 @117.69mph
 

you from stoon or what dude? im from NB if your from stoon ill probably be taking my truck to SIR some time id love to see your truck

Re: Ran 11.44 @117.69mph
 

Stoon is where I race, SDRA member #277.:) Let me know when your going, I try to make it whenever I can.

Our track is NHRA.

As far as the 4-link goes, mine has poly bushings, and by setting my coil over spring rate and preload my ride is just as good if not better than stock.

Eventually tubular front arms will be going on.

Re: Ran 11.44 @117.69mph
 

nice pass

Re: Ran 11.44 @117.69mph
 

I run a solid roller 489 BB, it dynoed at 640HP, 620trq. with a too small 750 carb. I now run a 850 Mighty Demon and have a NOS Cheater system. In ran a 11.72@115 with a 1.72 60' at the last street drags on motor spinning a bit at the start. My coil over springs were a bit too light and I was bottoming out when I launched causing it to bounce. It was hard to get a good run in the other night after the rain it was hot and muggy, I was running 12.01 and not impressed. On the 11.44 I ran a 100shot in second and drive, it was the first time the motor saw nitrous so I ran it rich and backed out some extra timing so I was not expecting that large of a gain. Well low and behold it hooked good and ran a little quicker than planned.

I'm pretty sure on a regular race day I would be around the 11.5's to 11.6's on motor. So I'm thinking 10's on a 150 shot should be a reasonable expectation. I too would like to keep the stock appearance, but a roll bar is a must. The truck will all-ways be street legal, but I don't drive it that much and racing gives ME more enjoyment than cruising, so not that worried about the 2 bars going out the back window.

Re: Ran 11.44 @117.69mph
 

Hey Jim, since they forgot to send me my NHRA rule book last 2 times I ordered parts. Would you happen to know the rule on tranny and flex plate shields?

Re: Ran 11.44 @117.69mph
 

By the way Thanks guy's.

Monty.

Re: Ran 11.44 @117.69mph
 

thats fast

Re: Ran 11.44 @117.69mph
 

Another thing to keep in mind with his truck is that it would even faster closer to see level. What is the altitude in Sask?

Re: Ran 11.44 @117.69mph
 

Not too bad, little over 2000 I think? Hoping to make it to Medicine Hat next weekend, they have a new concrete launch pad it's suppose to have bite.

Re: Ran 11.44 @117.69mph
 

10.00 and below need sfi sheilds, unless the firewall is not stock. 10.99 and below you need aftermarket axels/or C clip eliminators. 11.49 to 10.00 need a 5 point roll bar and sfi fire jacket.

Here is the online rule book

Thank's Jim.

Re: Ran 11.44 @117.69mph
 

2000 ft is pretty substantial though. According to NHRA's website at sea level you would be running 11.17 @ 120.52 at sea level. This is not really important at your track because obviously everybody is at the same disadvantage. It's just cool to see what would run at a track like Montgomery Motorsports Park or Silver Dollar in Georgia because they are only 400-500 ft. Here is the NHRA's conversion chart if you want to check it out.

http://www.smokemup.com/auto_math/nh...on_factors.php

My brother's '78 GMC has run a best of a 11.98 @ 112.11 (7.58 @ 92.86 in 1/8) with a 1.71 60' on motor with much less engine than you have. We'd only be in the mid 12's at your track. Here is link to his truck if you wnat to check it out also. http://www.bassettracing.cz28.com/photo2.html

Re: Ran 11.44 @117.69mph
 

Man! 71Dragtruck you and 57sailplane have big boy trucks. Good job on the run.

Re: Ran 11.44 @117.69mph
 

Nice truck your brother has there, I'm allways interested in checking out other drag trucks. Would be nice to make a couple of passes at a near sea level track. But it is cool when you line up against a 440 procharged Challenger, stripped interior, roll bar, open headers etc. and then the look you get when you beat him, PRICELESS. Icing on the cake is when he asks later how big a shot your running and you tell him that was just motor.:lol:

Re: Ran 11.44 @117.69mph
 

Which rule would apply, they have 2 different rules, or has it to do with stock floor boards.

Under general:


2.14 TRANSMISSION, AUTOMATIC

Any non-OEM floor-mounted automatic transmission shifter must be equipped with a spring loaded positive reverse lockout device to prevent the shifter from accidentally being put into reverse gear. Functional neutral safety switch mandatory. All transmission lines must be metallic or high-pressure-type hose. All vehicles running quicker than 9.99 seconds (*6.39) or faster than 135 mph (217.2 km/h) and using an automatic transmission must be equipped with a transmission shield meeting SFI Spec 4.1 and labeled accordingly. "Blanket" type shield, appropriately labeled as meeting SFI Spec 4.1 permitted. All non blanket type shields must incorporate two (or one, per manufacturer's instructions) 3/4-inch (19.1 mm) x 1/8-inch (3.2 mm) straps that bolt to the shield on each side, and pass under the transmission pan, or transmission pan must be labeled as meeting SFI Spec 4.1. Permitted in all classes where an automatic transmission is used. 9.99 (*6.39) or quicker ET cars, and 135 mph (217.2 km/h) or faster ET cars using an automatic transmission must be equipped with a flexplate meeting SFI Spec 29.1 and covered by a flexplate shield meeting SFI Spec 30.1. Air shifter bottles must be stamped with DOT -1800 pound (124 bar) rating (minimum) and be securely mounted (i.e. no tie-wraps or hose clamps.)


Or would it be this?

Under SECTION 1A
E.T. SUPER PRO, PRO, SPORTSMAN

7.50 (*4.50) seconds or slower:


2.4 TRANSMISSION, Automatic

Spring-loaded, positive reverse lockout device and functional neutral safety switch mandatory. Transmission shield meeting SFI Spec 4.1 mandatory on any car running 10.99 (*6.99) or quicker or any car exceeding 135 mph (217.2 km/h). Automatic transmission flex plate meeting SFI Spec 29.1 and flex plate shield meeting SFI Spec 30.1 mandatory on cars running 9.99 (*6.39) or quicker or any car exceeding 135 mph (217.2 km/h). See General Regulations 2.14.

Re: Ran 11.44 @117.69mph
 

hey 71 drag truck here are some pictures of the cage welded to frame underneath cab. if you need anything else let me know.

Re: Ran 11.44 @117.69mph
 

Thank's, that's a serious cage you got going there, you must be planning on some 9's.

Re: Ran 11.44 @117.69mph
 

yes i would be happy with low 9's since i am running a sbc 383 with nos. my combo might not be as large as yours but i hope it will go the distance.. i built it expecially for nos.. cam pistons and even heads were ported profesionally for nos.. anyways the weight thing is what i am looking at now. thats why i was wandering what your truck weighed.. anyways keep us posted on what your doing cause alot of us wish we were racing...
