What is the average trap speed

Increase when using nitrous to running N/A, spraying off the line or with RPM pills...

Just curious.......

hard to say because everyone's car is different. If you were getting 88 in the 1/4 before, I would expect around 97mph now, which is a fair increase.

trap speed would also be dependant on what size shot your using at the time.

Mine on just the motor has trapped a best of 102 MPH and 109 MPH on the bottle on street tires.

The old motor had trapped as high as 97 on the motor and 107 on the bottle and drag tires.

BUT there are other things to keep in mind.

Gears, Tire size and RPM all affect the MPH. That also includes traction. More hook usually a bit less MPH, less hook usually a bit higher MPH. Not always the case but a general rule.

Example: a 3.73 geared car and a 4.10 geared car, same tire size, all other things being equal the 3.73 car will turn more MPH likely especially if they turn the same RPM. Its the same as running on the highway.

Thats another reason why MPH don't really bother me either. The E.T. is what counts not the MPH you are running at the end of the track. E.T. wins races basically, not MPH.

I know it's the ET that counts but wont a MPH give an estimate or general area of what the car is capable of. Mark M's truck ran a 15.xx @ almost 110mph, which he said should be good for a low 13 or high 12 pass. Is this a correct way to project things. if I trap over a 100 mph, shouldn't that show for a high 13 low 14 pass? I have heard this many times out here, but never inquired about it till now. DO I have it wrong?

Thanks Guys

you can somewhat estimate e/t's by mph but it wont be exact. probably within a few thenths though. bad traction usually equals higher mph too so your estimates could be skewd.

Marks 110 MPH pass was without traction I can assure you. The truck is making power capable of low 12's if he can hook it up. Once he does the traction will come into play and the MPH may drop some. Depends on the tires, sizes, RPM etc.

Again based on that MPH it should be in the low 12 second range or better.

A 100 MPH pass could be a 13.5 - 14.3. Mine has done 100 MPH or a little over all through that area. At the same time it has also ran 13.8-14.0 at 95-97 MPH. Traction, power, RPM etc all play a part. Based on what I've seen you would be in this area, which is where I said you could be if all things are taken into account and traction is available.

Traction = E.T. MPH = HP

Which comes back to my usual point, HP does not always win races!!!

Dave, In your case and to be fair, if all is done correctly with the set-up the way you said it is, you are 13.7 -14.3 capable at 100-102 MPH.

Just a guestimate based on my previous set-up on the stock motor. I realize you have more than that so It could be better. Traction will be the key and how well you have everything set to run it.

You'll see what I mean soon enough!! Good luck and HANG ON!!!

lol.....

I do have a question for ya.

I currently have the shot at 100, yet I haven't used the 100 shot yet, the chip is burned for 100 hp....

I have a dyno tune with Jerry from SCT in October....Should I try the dyno tune on the 125 or am I asking too much from my stock internals?

You won't find a better tuner in the country than Jerry!!!! I'd have him tune it on the motor first and make sure all is well and get numbers to see what your making.

After that, make a pull on the motor with whatever shot you intend on running. That way he can see what needs done to optimize that tune. He may be able to set it so you can pull the Octane pin and retard the timing while optimizing things for the shot.

The stock bottom will handle it if all is well. I ran my stock bottom on mine for 5 years. The main thing is make sure everything with the set-up is optimal.

Also, Unless I missed it somewhere, are you Still running the stock TB? You may want to get a 70 MM Ford unit prior to the tune. More air in, more air out, the better she will run. Not a better time to do it either.

Should I go with the 70mm, and not the 75, and the Violin case is still on there, I need to swap that out before the tune though.


Also shouldn't you do the plenum if you do the TB. And is the 70mm unit you speak of the FRPP or SVO one or does it come off a stock year Mustang?

Thanks

since yours is a 95 I think you have to upgrade the intake and Throttle cable to make the Ford PP 70 MM part work. A-train would know more on that since he has done it before as have others on here.

Mine is a 96 and I didn't have to do all that.

I've heard something on this site about using an F-150 TB for the 94-95's, it fit without modification and was (i think) 70mm? I don't have any idea where I saw it, though.
