91 MTX 14.2 - 103 mph

[91PDXmocha]

Went out to the track tonight with some co-workers, decided to run the SHO and see about where I was at with the car so far.

Car is full weight+junkntrunk , 4psi stock motor , cheapass street tires at reg pressure. I shifted it pretty easy and was shifting early only taking it out to around 6300-6500rpm . I am still learning how to launch this thing with the power and ****** tires so was only getting 2.3-2.4 60ft times. Pretty sure there is alot more in it with some sticky tires and a good launch, high 13's on <5 psi would be cool .

im on the right -->

The left lane is a modded 1gen dsm that was like WTF ?! when I passed him in 2nd gear ha

Very nice , running with a tuner ? stock injectors?

4 psi untuned with the octane adj pulled , 91 octane . Yes stock fuel system right now, working on getting the rest of my fuel system parts right now.

What are 102-103 trap speeds realistically good for if I can get the launch down ?

a 2.4 second 60' is abysmal, even for a bone stock SHO. Get some good tires on it and you'll see much better times. I expect, at most, a 2.0 second 60' time with good tires and a good launch on 5 psi. Lookin' good otherwise!

I dont think I saw anything lower then 2.0.
2.5 is more average joe in a DD.

for most of sho owners , their sho is their DD and a track sho is pretty rare since its not a 1/4 car. So launching like a mustang is not likely , plus with our flimsy axles/tranny , you dont wanna launch it too hard.

You might wanna ask SHONUT , he might point you out on EXACTLY where your time should be.

103 traps are good for a 13.6 run. I ran 104 shifting very slowly

Also, that was with drag radials and a gen3 subframe. 2.0 60ft what size is that turbo?

Same as yours I think or pretty close , 60 AR 63 trim . How much boost where you running on those runs ?

Also, What size are your tires and how aggressive are you launching ? I'm going to mount 2 DR on a spare set of slicers for the track.
I'm jealous of your 60's

I think your turbo is holding you back a little.

I think your turbo is holding you back a little.

Very true, that's why there is a new one waiting to be freshened and installed.

 

[91PDXmocha]

wow, changed my platnium ngk's out for copper autolites 1 range colder and put on new OEM wires . Cleaned up a small miss I had at idle and the power comes on much stronger in all gears. More noticable torque steer in 2nd now. My "newer" old wires/plugs must of been worse then I thought.

Going to try and find a set of sticky tires before next saturday and hit the track again looking for 13's .

 

[SHOtime2511]

Platniums with a turbo is a big no no.

 

[91PDXmocha]

Yea I had the coppers sitting in the garage waiting for a decent set of new wires to put on at the same time .

With that trap speed I think you should be able to hit 13's as is (or maybe with some sticky tires). If you drop your 60' by a couple tenths you should be there.

Yea I know my 60's need work . I know I will hit 13's next week with just the tune up I did and lower tire pressure to maybe 20-25 psi . I also found out I was dragging the Sho with half coolant in it and cooking at 250 deg ( the gauge had been acting up ) . I had maybe 100lbs in the trunk as well , overall I'm pretty happy and impressed with how much power the car is making with my low dollar build and still running 5 psi . stay tuned for another 13 sec SHO next weekend

Lowering your Tire pressure on street tires is not going to help you. Run them between 30-35 PSI.

[91PDXmocha]

Thanks , ill try running 30 psi

btw the your sig is 100% truth

 

[Not4speed]

Damn that's a quick grocery getter! Very nice and looking forward to hearing about the next pass you make.

Great video, especially when Josh is jumping up and down at the end. Nothing like accomplishing goals!

That is my plan.





OH! You meant in the TIRES!
