My Quest for 13.XX version 1

[CDW6212R]

The cat pipes are restrictive in any application. Other than the headers on the Explorer, spend time making the cat pipes better.

 

[Turdle]

Jon, what was your RPM at the trap and what gear was the truck in?

Ummm, I was skeered and staring at the mustang that just ran an 11 next to me--

he was way down there--lol

I was like WTF was that?

 

[CDW6212R]

How long was it in 3rd gear before the 1/4 mile?

How long was it in 3rd gear before the 1/4 mile?

exactly--
I need to pay attention to a lot of things-and quit sight seeing--

 

[CDW6212R]

I'm not picking on you, I don't know what mine does either. Hopefully it will matter soon though. Skip what I said long ago about close ratio gears from an AODE, I read that they are not as strong as the wide ratios of the 4R70W. I love driving my cars knowing that nothing needs watching(except gas). A reliable vehicle is priceless.

Have you still got the stock cat pipes? Those have always been on my hit list, they are 2.25" and have sharp bends in them.

 

[Turdle]

yeah-stock cats. You don't think the dumps will help?
I need to be pulling harder from about 80 mph-I "think" it is shifting about 82 mph into 3rd-

so-it is barely pulling into 3rd at the 1/4 mile marker judging from the speed--

maybe hitting 3rd sooner would get it to mph?

It was in "d" all the time.

 

[CDW6212R]

I think that the exhaust after the cats are not as big of a restriction as the headers, and then the cats.

The 3rd gear is very bad for a short period, because of the big rpm drop. I'd check the shift rpm into 3rd, delay that to the top of the power band at least as much as the 1/2 shift.

When I was building the engine, most people I discussed it with were worried about the low end I would loose, so adjustments were made accordingly-

The cam has been advanced 4 degrees to bring the torque peak down.


So, now that we are really into the game-we see that horsepower is indeed needed over torque.

You would be surprised how many ~4000+lb 4.8/5.3 LSx trucks are out there running TR224/224 114 LSA cams with a 3600 stall and running 13's with just bolt ons. Your heads should flow more(or equal) to stock 4.8 heads, so I think the power is there, just untapped as of yet

The X303 has 4 degrees advance already(from what I read), so is yours advanced 4 degrees on top of that?

No-
thanks for that tidbit-because my engine builder needed to use the "0" shim to get 4 degrees.
I do remember this-as i have the remaining pack--lol

wow--

You need documentation like this Jon-- to jog your memory. http://www.youtube.com/watch?v=EuH-yy5Su48

I was watching the sights also, haha. It is easy to do when the only work is required at launch. After that it is just a matter of keeping the little pedal on the floor.

 

[Turdle]

I think I just thought of the thing that might get us there-

Remove front drive shaft.

The drag from rotational differences may have been dragging me down.

I had the same brand, same size, but different series tires front and rear--

the worn rears hook well, but the fronts are a bit larger-
hmmmm--

I am going to remove the front shaft for the Sunday dealio--

HAha--
you were looking at the girls--lol

 

[Charlie]

I'm interested as to how much removing the front drive shaft will do. I've read on here it doesn't do much to increase mileage if it's removed, but I wonder how it increases times....:scratch:

 

[CDW6212R]

It's worth a shot, but in 4WD you should have felt something if it was off. I tried to run 65 series snow tires with 70 series in front. The AWD did not like that, the diameter was off by over 1/4".

Hey--is that Rock Falls?

 

[99SportX]

Hey--is that Rock Falls?

Yes sir it is!

Jon, I thought you ran in 2wd. If the t-case was not engaged in 4wd, I think you would be ok since it would allow the front to spin freely, but I am not sure on the inner workings of that t-case.

 

[Charlie]

Wow! Is that really the closest track? That's got to be around 170 miles away!

I usually go out there a few weekends over the summer for fun..to watch, not race:shifty_ey
I guess I'm lucky having a track 10 miles from my house. To bad I don't have anything track-worthy.:

These are off by at least that also-

During the last 1/8 of the first 4wd run, I did feel a very weird "pushing" from side to side--

With the front shaft out the front drive of my 4406 will not be spinning-there will be a lot of rotational mass eliminated-

 

[99SportX]

Sorry Charlie. I totally forgot about you being down there. I was just concentrating on making it down there with the local club and completely forgot about where I was going geographically. lol It would have been cool for you to come by the track when I was there. The next closest track is Brainerd. People around here only go to those two places. Duluth sucks in that regard.

Yeah Jon, remove it and do a real 2wd run. Hopefully you can hook up enough to get a great launch.

Try filling up on some 100 octane race gas too if theres any by you. Might seem like a simple thing to do but it helps.
