well if ya want to get that thing faster ya need a few things that keep it relatively stock. number one get a better intake give that car some air. number two adjustable fuel pressure regulator more air needs more fuel. and number three would be better exhaust system if it is still stock this will make the car sound nice but still look stock. those three upgrades should make it a low 13 sec ets. sounds like ya got the chip working good. all of these are pretty easy to do and you can save all your parts to put it back to orignal. but if your lookin for 12s your going to lose the bone stock value to the car..

theres plenty left to do before braking the bank...shift kit in tranny if you wish etc

how much boost are you running?
where you on street tires at the track?? where they spinning badly?
what was the 60ft ?

do you have any scan tool data??

or a wide band ??

a major upgrade would be to get a better air intake.. the stock one is very restictive as Ed suggested

start with wat i said thats usually the most common things to do to your tr it will keep it stock appering and ull get low 13s with those upgrades.

FWIW, I got my 87 T to go 12.96 with no tourque converter upgrade, through the stock exhaust and catalytic converter, and on DOT tires. Did use a cold air intake. Just simple 'recipe' mods and lots of fine tuning with a scan tool.

You can't push things harder than the stock converter stall at the line. About 2200-2400 is all you will get. However, you can upgrade the rear brake cylinders to hold it back better. (cylinders from a 84 S-10 truck with manual brakes are a hair larger)

A scan tool is a must.

Read the Recipes section for most of the basics ...

http://www.gnttype.org/techarea/recipes/recipepage.html

As stated ... it's about more fuel/air and a chip calibrated to take advantage of that.

With good gas, some traction, a basically stock car (with air intake, fuel pump, test pipe, sticky tires) should be able to run solid 12s with sixty foots in the 1.6-1.7 range and trap speeds around 107-109 MPH.

This would require 100+ octane gas and 20 psi boost (and tuning).

Fuel Pressure 39 - 42 @ wot with 18 PSI 59
Sounds borderline low on fuel pressure up top. Still the stock pump and wiring?
Scan tool O2 settles to 800 - 850?
Which scan tool are you using? That may be OK, or may be rich depending on what you are looking at the data with.

Attached is a zip file containing the TunerPro support filis. The ADS file provides the ALDL data definitions and the XDF file provides the chip data definitions. As far as I know, this is the most complete version of these files.

what gear are you locking the converter ???

3rd gear @ 100 MPH seems to work well and doesnt tear up anything

Was that run with or without the TA49?

Any fuel map adjustments to accommodate it? You'll likely need them.

Good luck! :tup:

also i have never tried the boost a pump setup... but i have good results with the Red Armstrong twin 255 intank setup " known as double pumpers"
the second pump is activated but a boost pressure hobbs switch at about 8 PSI

new gm fuel pump
First, congrats on your times.

Second, you need more pump. That pump is not adequate. A stock GM pump was barely adequate on a stock car.

Also, I saw no mention of an injector upgrade. It is likely something you need now that you have additional air volume with the turbo. Might be why the car falls down on the big end.

I would NOT recommend the Boost-a-Pump. Is that the old Kenne-Bell geegaw meant to provide more volts to magically give you more fuel from the stock pump? Please sell that to a local Mustang racer and invest in a solid Walbro intank pump. Your head gaskets will thank you.

http://www.kennebell.net/pricelist/SC-PRICELIST.pdf

Over $200 for that! Please tell me you didn't buy that new... A new Walbro isn't nearly that much, and will damn near take you to the 10's!

Big gains in a short time. :tup: Great MPH with very little work. There is a different tire in there too, right?

I do still think the Boost-A-Pump is not scientifically sound. Obviously, financially solid (since it was free). Consider going in a different direction in the future.

I never got out of the 12's on stockers. Only got to 12.20. But didn't try harder because the chip I was using made it look like I was running mega-lean.

My first jump was to 36# "blue top" Bosch injectors. At the speeds you are going, I would suggest no smaller than 42.5# injectors, or go straight to the 60# Mototron/Deka/Siemens.

Are you saying you are using pure Methanol? Or is it auxillary injection (i.e. "Alcohol injection") used in conjunction with gasoline?

If you are using 100% methanol, you'd be looking at ~6.5:1 for stoich and for a safe under boost/enrichment you'd probably be in the 5:1 range or so (I'd watch an EGT reading and "sneak" up on it).

You'll also need about double the injector capacity vs. gasoline (and the attendant pump and fuel line capacity as well).

As long as the fuel is adequate, I'd start bumping boost a little. I'd be a little worried about the boost-a-pump set up keeping up, but if it can, then start sneaking up on the boost?

Especially in the lower gears where the load is less ... 20-22 psi starts really getting into the sweet spot of the TA49 compressor map.

Glad you can enjoy it and make it work for you!

Are you running the stock headers and downpipe? The headers can make more power, especially when ported. A 3" "Terry Houston" style downpipe next.

Certainly you have removed the cat at this point, right.

hello. Ive recently come to own a 1987 t-type. Ive been pondering just what i wanted to do with it. Its decent, but its showing its age and not really a show piece. Im thinking about running it down at the local strip (Beaver Springs Pa). I'd love to go there and beat some of the new muscle coming outa detriot. Its nice to know that your getting those numbers out of a more or less stock motor. Ive read through the different articles and learned some. Bur im still hazy on burning chips an all those settings, but im sure you guys will lend your advice when i get to that point. for now ill concentrate on getting to know just what i have. thanks for the posts
