Gears and transmissions?

[03slobra]

I have 28 11.50et streets with 410 gears and 5spd.On 150 shot Im having to shift at about 35 or 40ft out im going through the quarter at 7200rpm.Im going with a powerglide,with a spool will these gears be good for a hard launch with a 1.76 low gear and transbrake.The rear end is shot so I might as well do it all at once.Any suggestions?Any guys on here with a powerglide?

[QWKSNKE]

What rpm stall?

[03slobra]

I dont really know probably 4300, i leave between 4 and 5 now.

[Wickd GT]

With a Glide I recomend a 3.73 to 4.10. This is the thing, you can launch hard, but you still going to the traps at 7200rpm. If you are going to keep the 28" slicks, stay with the 4.10. That means about 600ft that is when you probably shift in high gear. If you drive in the street is going to be a bit anoying due to the 1st gear in the tranny. Stall should be at 3800rpm to 4000rpm if you are using nitrous. If I was you, I'll go with a solid roller with a tight lash, it will wake up that motor. I think the glide is going to slow you down a bit. I'll go with a bad ass C4 to keep the revs close to the power band and a set of 3.73 gears, then let her eat!!!

Sell the glide and I'll sweeten the deal on the C4. :nice:

What horsepower/torque does the engine make? And what RPM's do these peak at? Knowing this will help decide the gears and the right stall.

grrrrrrrrr , stay with 3 pedals!!!

The problem with 3 pedals in a nitrous car is inconsistency. Unless it has a pro shifted tranny, like a liberty, something that does not use the clutch to shift, but streetability goes up on smoke and the tranny too if you don't how to drive it in the street.

First of all thanks for input thats what im looking for is more opinions.Okay,I know its going to different on the street im prepared to deal with that.The reason for the automatic is its hard to get 500hp 650tq to the ground dumping a clutch I have a 1.57 60ft when i should have 1.35 or 1.40.It ran 6.80 1/8th mi friday nite I want 6.00 out of it.I dont know who all has seen it run but its very violent off the line it pulls the wheels 6or8 inches when i shift into 2nd.An auto would be smooth and consistant plus i can put a 2nd stage of nos on it.The motor is built very well it has a lot more in it i just cant get it to the ground.It dont matter to me which trans c4 or glide but glide is way cheaper.Im just ready to gettr done.Keep the suggestions coming guys.

Knowing this will help decide the gears and the right stall.It made 482hp609tq at the wheels on 150 with 8 degrees timing.I run different plugs now and 11 degrees timing on 150 shot.Its a n71 afm cam 110 lobe separation 232/240 dur 576lift 1.6 rocker.It has a 6600 shift point and will turn at least 7400rpm thats what msd pills it.PM me with more info on tha c4 Im still interested I'd still like to drive it never drove one with c4.

[coupe]

The glide will be tolerable, but you will want more gear...especially since you're running 1/8th!!!

Or the C4 would be perfect. I got pics of it in the F/S section now. :D

What block do you have? Is it a stock block or after market block. If after market block then 2 stage is fine, stock block, KABUMMMMM!!!! To run a 6.00 that motor be having more than 500hp. Another thing, those heads are small for what you want to do, AFR185s, are they fully ported?

So, you wouldn't recommend me running two kits?

It is a dss pro bullit longblock I've be running the piss out of it for 2 years and never had a problem with it.If somthing happens to it then I'll go with a dart or boss 302 block but until then i'm gonna give it hell.I know how much hp it takes to run 6.00 and i dont have it right now but i run 6.80 with 1.57 60ft on 150 so if I knock 2/10ths off 60ft and spray another 100 I should be somewhat close,my car is very lightweight.If i cant do it with this setup then I'll do 351 stroker assembly i already got a block waiting.I just wanna go faster and faster I think I might need counseling.lol:jester:

no need for counseling with wanting to go faster!,BUT,DSS has really gone to shit lately!,if you go on corral,or stangnet,do a search!,lots of people have been having LOTS of probs with their stuff lately!,I told Geoffrey about it awhile back,and not to get off of the subject,but I saw your car a couple of weeks ago in the parking lot when you drove it to work,and I have to say the pics do it NO justice! That thing is SWEET!:smokin:

Well with 150 shot you are safe, once you get to that 200 and above is when shit starts to happen. Dss pro 10, 20 or what ever it still a stock block. Lets see, put 250 shot, put some racing fuel in it and cold spark plugs, and take out 9 degrs of timing, a little detonation and the mains will be holding the crank from falling in the oil pan, LOL. If you decide to go with an after market block, do not get the new Boss block, the sleeves are too short, 4.50 compare to the R block or the dart block, which is 6.50 cylinder.

Italian, your block will last a bit more because is a 351 base block, but it is still a 2 main. When the nitrous is on the 150-175 level it is a bit safer, but when you start 200-300 shot now it is in the good tune up area that will make it survive. Remember this, heat produces a lot of detonation. My question to both of you, Preston and Brian, did you guys file fit the piston rings to use nitrous? If they are not file fit, nitrous makes them butt and then the rings start to rattle in the piston causing fuel to stay between the top and second ring and that's when you either lip a piston or blow the top of the piston, but this could happen at any level of nitrous. Just my .02.

[Italian LX]

My question to both of you, Preston and Brian, did you guys file fit the piston rings to use nitrous?
Yes, I file fitted the rings for nitrous. However, I used the low side of the tolerance since it's more of a street car.

At this point, I don't plan on putting more than a 200-shot on it. The reason for the two kits is so that I can launch on a 100-shot and let the 200 take over from 2nd on.

[QWKSNKE]

Preston's car is a 1/4 mile car unless he is changing

[coupe]

DSS has really gone to shit lately!,if you go on corral,or stangnet,do a search!,lots of people have been having LOTS of probs with their stuff lately

People on Corral & Stangnet have problems with shit period. It's not an issue of DSS. Their stuff is just as good as the next machine shop. Actually very consistent.

QWK, Preston's goal of 6.0's are why I mentioned the 1/8th mile.
It will be a risk with a stock block, but if the tune is there, and the rotating group is decent, it might do it.

nothing against you brotha, I hate when people say that, its so untrue, if you are running inconsistent its not the car, tranny etc, its the driver. Either one of my cars I can run within .01-.03 every pass, and thats with either a 400HP street car or a 762HP race car.

Naturally aspirated yes, on the bottle it is a very different animal. I have been a 3 pedal all this time, but I could not get the same consistent launch at 5000 rpm on the juice, and shifting in 2nd with the third pedal always pulled the tires and that was wasted times. To make it work better have a ton of money to have that chassis top shape so it can respond to what you throw at it.

You just talked me outa building a 331 lol. My car is a heavy full interior '89 Gt with a DSS longrod 308 and AFR 185 heads .228 .550 cam 9.5:1 motor with a C4 and ATI converter 410 gears. I have ran a 6.79 1.54 on a 150 shot with an AFR of 9.5 rich.

Not flamming ya or anything, just surprised.

[04 Mach1]

1quik85gt I think you jack your car up so the front tires are 3 foot in the air then climb in a pratice shifting, that has to feel so unnatural. I love watching you run whether its the stang or the fairlane.

EdgarI agree edgar on the motor i can run 11.50to11.65 all day but a 1/10 can cost you the win somtimes,when your up against someone with transbrake,delay box etc.I just want to be consistant as much as possible.

[03slobra]

Preston's car is a 1/4 mile car unless he is changingI'm still gonna run the quarter but focus more on 1/8th mile With the coupe.I've still got the lx to play around with.

In a true 1/8 mile track, matter of fact two of them, breakaway and Cottonwood in Dothan, both are true 1/8 mile tracks.


Edgar

[onebad12]

Like Edgar said, I ran that at acouple different tracks. It went 6.97 on 100 shot and drag radials. So I guess its a pretty good 308 lol.

Edgar knows my car better then anyone, he has helped me out with it alot.

I talked to Marc today, and he was telling me somethings about your car, I have never actually watched your car leave the line. From the conversation, I think your car is too violent because of the 90/10s you have on the front of your car. You have too quick of a front end lift. My opinion is put some adjustable shocks on the front, and let your rear tires spin no more than 2 rotation. I dont know how much your car weighs. I cut 1.40 60fts everytime I let the clutch out. Consistency!!! I dont know what clutch you run either, but that has some to do with it. You need to let the car be sorta controllable off the line but still pill the pavement. Bring your car to my shop, I GURANTEE it will cut 1.40s on motor and 1.35-40 on NOS.
