High 13's Possible?

[90LxDroptop]

Hey everyone. Just curious as to What I would need in addition to what is listed in my mod list, that would get me a 13 second time slip? (high 13's) What would u guys do next. I was thinking a 2400 torque converter? what would u guys do. I don't really wanna use any juice either.

A converter along with the drag radials will go a long way to improving your e.t. In addition to the converter, I would also change the exhaust. The most improtant piece in the exhaust is the h-pipe. The stock catalitic converters are very restrictive. I would look into an off-road h-pipe if you don't have to worry about emissions. If you have to comply with emissions, I would get a h-pipe with cats. There are a ton of exhaust companies out there so take your pick.

These things will get you close to a high 13. With a good 60 ft time, you might see a 13.9. The only way to find out is to go to the track and run it. FYI: I had an AOD GT (91) with just a converter and gears (3.73). It went 14.6-14.7 but with a crappy 2.2 60 ft time. If you can manage a 1.8-1.9 60' with the drag radials you will be close to that high 13 timeslip. Good luck!

Pull your front swaybar, and bump the timing, maybe run a short belt.

It was sort of evident by your name

It's hard to estimate what you may run if you don't say what your previous best was. I would say that the stall and d/r's will help tremendously, the biggest problem you have is probably weight, other than the aod. It's gonna take more hp to get that pig down the track. You could use a 65mm tb, headers, an adjustable fuel pressure regulator, a taller gear (like a 4:10), and very aggressive driving. With all that I would think your a lock for high 13's.

A guy in my club just ran a 14.6 with a bone stock aod hatch on radials yesterday, he was walking around afterward like he just got laid for the first time

Well that means it will be harder, heavy vert aods are hard to make fast, but of course you can hit 13's, I know I could, one thing that helped me hit 13.9 on street tires was an electric fan, i think my clutchfan was failing, but i really dropped like 2 tenths and gained 3 mph....just a thought. good luck

thanx guys!

What kind of fan did u buy, that made such an improvement?

[Coupe5oh]

Chrislx, i think you mean steeper gears, and a 65mm tb wont really help, unless you get an aftermarket intake, I bought the black magic fan, specifically for the 5.0, you can buy a cheap one from autozone, but i want reliability, and mine has been great, no problems......good luck, also some 1.7 rockers might help you out, im about to install some, i will let you know what kind of e.t i gain, im looking to trap 101 mph with a fpr and 1.7 rock's....

Look at my sig. with all the crap I got I pulled a 13.8 on the G-tech.....The track has been rained out 2 weeks in a row maybe this saturday I will get some track times.

Yea...that was me...14.66@96 on a street tire..."STOCK"..Timing is the key...and shifting!!! I am going to try for low 14's next time out...Track Sucked!!! Car ran that pass without a belt at all..Went 14.88@94 with the stock belt w/ A/C & smog pump.

I recomended the 65mm tb because i thought he had a 76mm maf for some reason, my bad. Besides i had a 73mm maf and a 65mm tb on a stock intake and heads and hit the 13's with it. Is there a difference between steeper and taller?

[stanger8172]

OUTPLAYN,

Did you go race at Great Lakes Dragaway?

[Coupe5oh]

sorry chris, I just though taller meant higher (numerically lower)...

anyway, I have been told a tb and maf is a waste on a stock motor, but im glad to hear it's not, because i want a new tb myself, my friend has a 65 mm tb and I can stick my finger in the tb, and feel the ridge on the plennum inlet, which is only 60mm? if anything that would create a turbulence that could kill power?

Here's what I had when I got into the 13's for the first time when it was still an AOD car, 13.99 as a matter of fact.

full exhaust, cheap tires, cheap stall converter (stalled at like 1800), 65mm TB, speed density still, ram air, subframes, control arms, 3.73's, pulley's. I think thats pretty much it.

Go for a PI stallion converter, they are expensive but WELL worth it. You may also want to think about 4.10's

good luck,

Stranger...Nope...I went to Byron...the track was very bad...looked like a motocross track when we left..I am hoping to get it down in the lower 14's while being stock..

I dont live far from Byron at all.. I hope to go on Sat again!!!

Coupe5oh, I took a dremel and ported the inlet on the intake to match the 65mm tb, took like 15 minutes. Unless you get a bigger maf the 65mm tb is kind of a waste though. If you are never going to get heads, cam intake, then the TB and MAF are probably a waste of money, but when you plan on making those big investments you need the peripherals that will make them work to their potential, such as the tb, maf and exhaust. Mine was a slow build, due to lack of funds. First I did the exhaust, then the TB and MAF, then I did ca's, sub frames and the clutch, then I did pulleys and ignition and then over this past winter i finnally got the heads, cam and intake. Made my best run with the stock long block with the bolt ons last fall, 13.98 @ 96, and I felt there was much more left.
