My turn at a guess-my-dyno thread.

I know these can be annoying as hell, but I have always wanted to do one.

Here is the setup:

2004 Mustang GT
4r75w transmission
Paxton Novi 2000 with 3.5" pulley. Seeing about 10-11psi at 6200.
Powerpipe
Treadstone TRV25 IC
Tial 50mm bov
Longtubes, 75mm TB and plenum, bla bla bla.
Houston Performance HPs292 blower cams.
SLP LM2 Catback with OR x pipe.


Dyno is a Mustang Dyno. I have talked to several guys that have dyno'd there, and there numbers all seem to be pretty reasonable for their mods. Should be interesting.

Here is what we are working with:

Closest one to guess wins... something? Dyno will be taking place Friday at 9am, weather permitting.


What does your dyno sheet trap?

A manual with 11psi on that setup would be around 475whp.

Arent the Novi 2000 similiar to a D1 cfm wise? My guess is 435/410. Good luck!

On a Superflow dyno the torque values are inflated higher than the hp because of the way load is applied. I was originally going to go to one, but decided on this dyno instead.

I hope the numbers are worse than what you predict . As strange as that sounds, I don't the car to tear itself apart. I might turn the shift points and timing down if the numbers come out too high.

What SRT said (ie you'll make 40 hp less than a manual would) is what I've been hearing also for the 4r70w and 4r75w autos so keep that in mind when you get your numbers.

This is with the converter locked, I'm assuming yours is locked at WOT in 3rd.

Good luck, I think I'd be too nervous to ever put my car on a dyno.

I'd want to do it like they do a space shot, with 50 guys sitting watching monitors of very possible thing you can measure, including the pilots rectal tension so they can immediately shut down on every possible "oh shit" occurrence.

And that is if the stock converter locks up, a friend of mine made 350+rwhp and 350+rwtq with a p1sc procharger setup 3.85 pulley on a stock long block, stock converter and stock gear and converter would not lock up.

Don't Mustang dyno's tend to read lower also. I know when i was on a Mustang dyno it was 35hp less then a Dyno jet.

yes and no, all according on how the Dyno Jet is calibrated. At JMS, they have a dyno jet and mustang dyno. They say that whatever you make on the dyno jet, you will make the same numbers on the mustang dyno.

There are two types of Dynojets. The early ones didn't apply load so they reported slightly higher numbers. They also have the option of reporting STD corrected numbers which inflates them even more. If its a loaded Dynojet reporting SAE corrected number then it will report almost exactly the same as a Mustang Dyno. My car's been on both and their was very little difference except for the one Dynojet that reported STD numbers. When I asked about SAE numbers he verbally told me the same as all other dynos.

10 psi + bolt-ons should get you near 400 rwhp. Those cams have been known to add around 40 rwhp but you'll have 5% more parasitic loss for the automatic. I'll guess 420/395.

ProCharger P-1SC, 9 psi, STD 396/383; Uncorrected 388/375; SAE 383/370.

Using the tune now, but with more timing. I have a few prepared that go up to 20.5*. I'll add timing until it stops making power, then back it off a bit more to keep it safe.

GTo1 on here had the same issue. I'm running 3.73 gears so I am hoping that I will not have an issue. I will be LIVID if I am going to have to drop the trans to put in a bigger converter before the summer. The converter held last time I did the pull on a DJ and made 383, which should have been around 360 on a MD, so I think if it was going to have trouble it would have already.

Quite so, but one that I feel is suiting for a man who won't give me the extra 2rwhp.

Going to London Chassis Dyno. I wanted to go to Lee, but he is so packed I don't think he wants to fool with letting me borrow his equipment. I had an appointment at Speedy's but canceled so I could go to this place. They are known down here for being the best at setting up suspension, and I am going to need some work soon, so I thought this would be a great opportunity to establish a relationship with them. Plus they are closer to home.

Gonna try my best to get off work and ride up there to watch. You should definitely hang around till that evening and head to the drag strip and we will run em. Should be close especially since I'll have the upper hand off the launch but you should pull hard on the big end. Then if u wanna have some fun we'll slap my slick on her and see what she's mad of.

Right, which is why I'm hoping for 400-410 at the max. If srt10ram can keep his alive at 440rwhp for a year, I should be good at around 410 with an auto hopefully.

And you are correct. Dyno will be done locked in 3rd.

Nice. Honestly, I would rather flog it on the dyno than the street. When doing datalogs, I was sliding all over the road, and the pull only lasted a few seconds. Plus there was issues with police, idiot pedestrians, and deer on the road. I was really maxing my comfort zone try to keep one eye on my wideband, one on the laptop, one on the tach, one on the boost gauge, and one on the road. This is also an opportunity to hold it at WOT for several seconds. On the road, within 4-5 seconds I'm hitting 6000rpms in 2nd and have to let off. Plus, even though this guy isn't tuning the car, he is still a professional and is very skilled at listening for detonation. If anything goes wrong, it will be in a controlled environment at least.

Awesome! I'll hang around, but I'm not sure what I will do until the test-n-tune. That will be a lot of time to kill, haha.

Man if we actually line them up with me having street tires, it's going to be a shit show lol. I'm down if you are though!
