My Quest for 13.XX version 1

[Turdle]

For the record I did win a race-
There was a patchwork El Camino with a radical camshaft being a nuisance right next to me while we were in the staging lanes-
he could barely keep it running -and was dripping transmission fluid. When we did finally get called out-He caught on fire after his burnout-so I had a bye run--lol
I launched the first time, in 4wd

R/T .728
60' 2.149
330 6.136
1/8 9.547 @ 72.03
1000' 12.536
1/4 15.096 @ 87.75

I'm planning on going to Mokan Sunday and playing with the shift points, timing and air fuel ratio a bit.
It is already shifting at 5800, carrying well over the 6k mark during WOT shifts. I'm going to mess with the shift points last, only if needed.

Then I'm going to get some exhaust dumps installed upstream of the mufflers in a couple weeks to really open things up a bit.

I will also remove the skid plates, and rear seat. I'd rather haul all the mail, but will shed a few more pounds to hit into the 13's

I cannot afford a turbo. I would like the power, but I'm afraid of what would happen to the off road capability. I already have issues with a heating transmission while climbing high roads.

The speed quest will end for this truck when it breaks the 14 second barrier.

No turbo for me either. I feel like I've already dumped way to much money into this thing to still have a 16 second truck. And I've pretty much accomplished what I want out of it. So the mod days are over for it except for a few little thing here and there. I'm just going to save my money and try to get this thing paid off in the next 8 months or so and then start looking for a car.

Is my stock exhaust going to be a problem then? LOL,

Is my stock exhaust going to be a problem then? LOL,

That's what I want to find out-
With all the work I have done, something isn't quite right.

I looked at the time slip again, and noticed tha mustang which spanked me ran a 11.8
his 1/8 speed was 95 mph, and he only picked up 22 mph in the last 1/8

I think to hit my target 13.99 I will need about a 80 mph 1/8 mile speed--

( actually about 82 mph) which would be a 9 mph gain needed. I can do this.

I won't lie either, I wish I went faster for the amount of money I have spent on this truck also, but the reality of it is this. How many of the vehicles at the track can be driven all year round and go the places our trucks can go? I am pretty confident that my explorer was one of the fastest cars there that would be able to be driven home without worry, make it through some nasty snow drifts, etc. I got whooped by a honda del sol, but he had to put on drag slicks to hook up, where I just ran stock good year wranglers, haha. I also doubt I will see him driving around in the winter (I know him, he doesn't). He also towed it there because he was worried about breaking an axle. Were any of you guys worried about breaking parts? Not enough worry to tow it to the track, that is for sure. All I did was pull up, take my spare tire out of the back hatch, set it on a buddies trailer, and go. No dinkin' around, left the interior intact.

My truck is a lot of fun to drive on the street, and it accelerates plenty fast for everyday driving, especially for what it is. I know it is a little depressing to see some POS cars that cost less to build run faster times than you, but try to think about the big picture.

Jon's case is a little different though, he should be able to get a 13, he deserves one! lol

I guess I meant a turbo for me, as my name is Eric also, lol. Although it wouldn't hurt for techie to get one either.

Just random thoughts.

I think my stock front 2 cats are causing some restriction.

 

[Turdle]

I was going over evrything in my head-when I came up with a brain storm-

My moon roof was open. dohp!

also-2nd run my windows were down. WTF is up with that?

 

[CDW6212R]

I'll see how bad it can be with a stock exhaust first, that is if the plug wires will go on. The stock cats are not good for any fast times, and the cat pipes are restrictive like the headers are. Those need to be 2.5" at least for a strong V8.

 

[chriswells78]

If you want to go faster, gears and tires are your answer IMO. Your running bigger tires anyway. In my Mustang, I picked up .3 going from the stock 3.27's to 3.73's. 4.10's should pick you up a bunch with all that torque your making and would also help you a bunch off the line if paired with a good set of drag radials. Especially if you get some drag radials that are somewhat smaller than your stock tires, they will be a multiplier to your gear selection.

I totally agree I love my truck for what it is, and it's fast enough that it can hold it's own with with a lot of cars at the track especially up to an 1/8th mile. But where it's at right now if I'm going to get it much faster I'd have to spend a fortune to do it. And maybe someday I will but right now I just can't afford it, especially since it's my daily driver. And it will stay in that role when I get another car so I'll have the time to work on without having to rush to get it back together so I can get to work.

I'll see how bad it can be with a stock exhaust first, that is if the plug wires will go on. The stock cats are not good for any fast times, and the cat pipes are restrictive like the headers are. Those need to be 2.5" at least for a strong V8.

Are you still planning on running the stock exhaust manifolds? I sure hope not.

If you want to go faster, gears and tires are your answer IMO. Your running bigger tires anyway. In my Mustang, I picked up .3 going from the stock 3.27's to 3.73's. 4.10's should pick you up a bunch with all that torque your making and would also help you a bunch off the line if paired with a good set of drag radials. Especially if you get some drag radials that are somewhat smaller than your stock tires, they will be a multiplier to your gear selection.

I'm not sure that 4.10's are the answer, I didn't pick up any time at the track, I picked up a little in the 1/8th and lost again by the time I hit the 1/4

 

[Jakee]

JT - Do you know the exact weight of the truck?

 

[CDW6212R]

Stay with the stock gearing until you change to off roading tires. The 3.73's are the best for the 30" tire sizes. I'm going to hope to hold out with my exhaust until I can make final changes that will be best for a turbo. I can't test fit my cast iron manifolds until I pull the old engine out. Then the plug wires will be checked for clearance.

Psst Jon, add a little NO2 to get there, and then you are done.

 

[RubySlow]

You Know Jon, Or Smitty is what Id like to call ya! I didn't even realize you were talking about the track. I had assumed you were talking about offroading. Anyways Im suprised about the times, I know there is more potential. I don't think it's the loose screw behind the wheel, I believe there is a loose skrew somewhere in the car.

 

[jah81592]

The vid wasn't bad.

Jt
I believe with just a few more practice runs you'll be in the mid to low 14's...go back to duels and 13's for sure. That's just my opinion and I know you're going a different direction now with your truck.

A single 3" will give the same performance. I guarantee you that duals won't help.

Believe it or not, you can gain a BUNCH messing with the locking and unlocking of the torque converter. I have a testing ground where I measure the trap speed at the end of the 1/4 mile. I was trapping at around 100 MPH and when I got the converter locking up just right, along with adding more timing, I'm trapping somewhere in the neighbor hood of 110 MPH. Now, I need to go to the track so I can see how far off I am cuss it may be a different story their. Anyways, enough with that.

JT - You're right, at least you've went to the track and also to the mountains. Most of all, you're having fun doing it and that's all that counts. A 14 second heavy SUV is impressive.

Jake, Do you realize that 110mph is a high 11 sec/low 12 sec ride in the 1/4. Go to the track, I believe your track results will be different. Just learning how to drive your turbo combo will take some time. Driving on the street is completely different.

Everyone messes up at the track. I always ensure that I have all high current electrical items off (a/c,blower fan,etc), only run the parking lights and close all windows & don't let your truck idle the entire time you are in the staging lanes. You are only building heat-which will hurt your et's . I see an easy .5 sec shaved off your time just with the 60' times and driving methods changed. Once you perfect all this then I would start changing shifts, A/F,etc. With your stall I see alot of potential.-j

 

[Jakee]

James - A single 3" is good for a 347 stroker motor? I still can't agree with this all the way, but you do know your stuff. I believe duals are the only way to get the full potential of the 347 but that's my opinion only. I'm not suggesting a change here but it would make it easier to get to the goal.

I'll get to the track as soon as I get the fuel lines fixed.

I'm going to install dual cutouts upstream of the muffs--

Will that do?

The area of one 3" pipe is very close to the same as two 2.25" pipes. That's the stock sizing on every 302 HO made. Dual 2.5" tailpipes is plenty for most big blocks and hot smallblocks. The pipes that run over the rear housing are the important part, make sure that the bends are mandrel bent.

 

[Jakee]

Dual cutouts should do the trick.

We're not talking about a stock 302 here, were talking about a 347 stroker with heads. Also, the exhaust is traveling a lot faster near the engine so if you want to be concerned with something, you should be concerned more near the engine. This is exactly why you see mufflers installed near the rear bumper now-a-days as opposed to yesteryear. The same muffler installed near the rear bumper VS near the front of the engine will be different. (Better near the rear bumper in most cases because the exhaust is traveling at a slower rate there, which results in the muffler being less of a restriction) I do agree with Mandrel bends thru-out the entire exhaust; however, if I had just two mandrel bends left, and had a choice to either put near the engine, or near the rear, I’d choice near the engine everytime.

Then again, we're just trying to get JT to the 13's. Dual cut-outs and different driving habits will most certainly help. Actually, he may already be there.....who knows?

 

[Turdle]

Thanks for all of the input. I really do want to achieve this goal.

 

[99SportX]

We need to rename this thread "My quest for 13's in the 1/4."

Would a 302 such as mine benefit from a dumped exhaust, or would that kill my torque and slow me up?

I re titled the thread-

With your camshaft, and a need for high rpm pull at the end I would say yes-
