Well Just Got Home From Dynoing the Stang and I must say I guess the stock motor has had it. I was not impressed at all.

My Goals:

180-195rwhp


Runs:


Run 1 All Motor Run:

Avg HP: 167
Peak HP: 178

Avg TQ: 197
Peak TQ: 232

Run 2 125hp Shot:

Avg HP: 202
Peak HP: 228

Avg TQ: 238
Peak TQ: 283

It was on a Mustang Dyno and all i can say is o'well time for MMR900 and Other Goodies

Those numbers are interesting. You have quite a bit of bolt ons and it seems like your numbers should be higher especially with the NOS. Perhaps your engine is tired after great years of service

I dont really get Mustang dynos. The numbers are sensitive to the weight entered in the machine or something like that. Either way they are always low. Just get on a DynoJet. More importantly what was the AF ratio???? Your nitrous numbers are awful. NPIs usually do well with nitrous.

Do a compression test and see if anything comes back wrong.

If the motor is healthy possibly there is a problem with your transmission... definatly doesn't seem right as stock non-PI's can put those numbers down.

WHOA! I think it's time for you to hit up your local salvage yard and have a PI 4.6 pulled out for a few hundred bucks and then installed for a few hundred more bucks. Will be the best money/mod spent on the car. The nitrous is the most baffling thing - what did your A/F ratio look like? Were you able to see the load on your fuel injectors during all of this? Possibly running a dirty fuel filter? With those mods I would expect you to hit at least 200rwhp without the nitrous. Go visit your local junkyard!

Da da da da dayum! +1 on the compression test. You're probably right aboot the motor being aboot shot, but it's always nice to KNOW first before you count it out

wow in my 97 gt convert. i barely pulled 215hp thats with an exhaust and cold air with 85k on the clock in my oppinion the non PI's are the black sheep of the 4.6's but you can fix thet with a head swap... sounds like she's tired
