87 Mustang H/c/i At Atco 13.5@102 2.0 60' - Vid

[00whiteGTvert]

Ran the 87 for the first time today (Easter Sunday) in nice 60 degree air right off the highway.
327 stroker with H/C/I, Built AOD, 3200 stall, 4.10s, MT DRs.

Not bad, 13.5@102 on a 2.0 60', car should launch harder?

I think the tune is set up for Nitrous which I disconnected, needs to be leaned out for NA.

Time to hit the dyno.

Second warm pass I swear I heard pinging on the big end, bad run of 13.6@101 on a 2.1 60', car won't launch hard?

I would hope you can get it dialed in better...my 87 GT vert speed densityAOD..3.55s stock long block just short headers,gutted cats,flowmaster cat back. on street tires 2.0 60ft ran 14.0 at 96 mph...all I did was bolt on a powerdyne..BD11a still on street tires I ran 13.1 at 103...2.0 60ft again...I think you should be better then me...with a H/C/I probably needs a tune....good luck keep us posted...

I'd be somewhat dissapointed with that mph and time with a H/C/I and stroker. Def get it tuned.

I definitely thought it should come out harder, at least 1.8-1.9, that alone would drop the times to low 13s.
I also thought the mph would be a bit higher, more like 104.
I think a tune should help.

I do worry about the pinging I heard somewhere around 1/2-3/4 track on the second pass.
The car supposedly has 10.8:1 compression, might need more than 93 at the track, but they had no race fuel available today.

what was your total timing set at

That is the problem, I don't know.

 

[mikestang63]

That is the problem, I don't know.

easy to check. with the spout connector in, rev the motor to about 3000 rpm

Easy enough, I've been away from fox bodies for a while.
My buddy has a mobile dyno and does dyno-tuning.
I will just do all at once.

Don't spend money on tune until you are POSITIVE that what you have is running right. It doesn't sound like it is.

That is why my buddy will check it out.
It really needs a switch chip, car has Nitrous which would be a different tune than without Nitrous.

If the track is open, they are selling race gas. Not that you would ever need it with your setup, I'm just saying. If the car is pinging going down the track you NEED to take care of this FIRST!! I second that this combination should run better that it is. You have some looking into things to do. Why exactly would you even think about racing it without setting or knowing where the timing is set at??

If you have a calibrated meter and the right injectors, just pull the chip out, check timing and fp and run it.

Out of curiosity who would tune a street car for nitrous only and not have a NA program?

Wondering the same thing...

 

[VibrantRedGT]

Sounds like too much timing from what you described which is actually hurting performance.

which is why I asked him. Running at the track with no idea about basic stuff like that boggles my mind. Things that go BOOM

 

[MY 85 GT]

Wouldnt a nitrous tune have timing taken out not advanced? so why is in pinging then it shouldnt be....

 

[Grabbin' Asphalt]

i would check it with the spout out and in and see where its at and where is it going. Maybw even do that with chip in and chip out.

The previous owner did this and told me it was safe, my bad.
I have my buddy who is excellent and will dyno it and tune it, his wife works for me. Nice business perk.
He did my 03 Cobra to 492rwhp SAE way back when.

Will find out soon
