He is finally making some torque at least!

We think these numbers are off guys. We are going to take it to a Dynojet ASAP.
Edit: Those TQ numbers dont sound right either.

I'm disappointed with the results. Is that the stage 1 kit with a 8 psi pulley? I know your running the LTH's too ... but damn!

I hope the new dyno shows better results ..... but damn!

Going to install the stock headers and a high flow cat with CBE and see if it improves?

That is on a Mustang dyno that reads much lower than a DynoJet

I beg to differ, this is actually a great starting place right now.
The car is running an 8PSI pulley, combined with the long tube headers and aftermarket exhaust it is opening it a lot. Hopefully we can get a smaller pulley soon and jump back on a dyno to see how things improve when we run the car all the way up to 8PSI.

I know many of you want me to just throw back on the stock manifold and cats, but that is not going to be what is happening.
This setup is working very well, we are running an 8PSI pulley which was designed and tuned for stock manifold and cats. Nothing is disappointing or "wrong" currently, this is about what I expected with my setup. This puts us in a great position to work on this car and provide the best possible setup for what we have, and improve this platform beyond what anyone was expecting.

My setup from the start was not going to be an exact 1 to 1 copy of what GTM is producing. I have decided to go my own route with the long tube headers, and Sam at GTM is helping out tremendously on this and we hope to move forward with some great results soon.

Awesome. Cant wait for new results

Some of you guys are pretty clueless...just because its not hitting 8psi of boost, it doesnt mean he isnt flowing the same amount of air he would be at 8psi. Yes its more free flowing, thats why the boost doesnt build up. The problem is that he CAN'T just keep adding boost because that will add air volume. The real engine killer is flow, not psi. So for those of you who say "oh we can just add a 12psi pulley and it will even out" that is not the case. The motor wont last.

You are better off running 371whp at 5.5psi if that is what the car wants to do. I wouldn't push the stock block too far over 450whp on a dynojet on a car that will not be running race gas regularly.
371 on a mustang dyno is about 415-420 on a Dynojet, I guarantee thats what you're going to find. ( on a side note, stop rushing to find a dynojet because you think these numbers suck) The dynojet isnt going to make your car go faster or flow better. I know you want to see higher numbers..

FWIW...my advice would be to leave it as is and enjoy your car where its. Its safe, its making good power. Don't go risk something and waste more money just because you want to make people happy.

It does sound like a good plan and I wish you all the best in your results.

I am following this thread closely because this is the direction I wish to go too ...... if I EVER get delivery of the SC before the end of summer.

Out of curiousity .... what is the diameter of the 8 psi pulley? and I'm assuming this is the stage 1 SC?

Thanks

RCZ, definitely in no rush to find a dyno jet, it will just be something on the to do list once I get everything back and things settle down a bit. I am very excited to get the car back tomorrow, it is being sent over to the audio shot to fix a slight bulge in the screen and after that it is mine. :)

Zat Zuma, this is the stage one SC kit, on the size of the pulley I will have to get back to you on that, or if someone else can chime in and answer that would be great.

And for those in Houston, it will be at Planet Zero tomorrow for the Access Zero meet if you want to see it.

Everyone in here is nuts to think those TQ numbers are normal. I could be wrong for sure, but they look real high.

Dreamer, I think you have the right idea and you make a very good point. The tune you were provided by Sam was for stock manifolds and cats. Adjusting the tune to include the long tubes will make up for some of that difference.

An example of a long tube header installation on a supercharged vehicle was a Kooks long tube header setup on a supercharged Saleen S281 Mustang. I have included the video below. After bolting on the headers, the installers retuned the vehicle to account for the new headers and made an additonal 40 rwhp and 35 lb-ft of torque.



RCZ, I'm not sure I agree with air flow being the killer of an engine. Your engine can be thought of as an air pump. In order to make gobs and gobs of power, you want to inhale and exhale as much as air as possible. This in turn means you can burn more fuel. This is where forced induction comes into play as turbocharger and supercharger kits will increase the mass flow rate of air into an engine. However, when picking a forced induction kit, you need to ask yourself one question; "at what PSI can I meet the required mass flow rate of air to reach my goal for XYZ rwhp?" More often than not, stock rotating assemblies will be the limiting factor in reaching your horsepower goals. The additional PSI will raise your peak cylinder pressures which not only means added compressive force on your pistons, but increased cylinder temperatures which leads to detonation.

How was this tune based off stock headers again??? I could be wrong but Sam built this tune in a 4-5 stage process because the first tune would not start. In turn a whole new tune needed to be built around Dreamers ECU in 4-5 stages. Once again I could be wrong but this tune was not based on the stock headers but Dreamers current config. I really think the mustang dyno is NOT giving us the data we need and I will talk more on this later. Once again I could be wrong but until the car gets to a dynojet I cannot say much more for this matter. Dreamer, if I have to pay for the dyno myself I will, but lets put this thing on a dynojet, we need more pure data. .

Edit: For the note, the current tune that is on the car could not have been better built. The car is running perfect in every way and the data proves it. The numbers are oviously off in conjunction with the psi levels, and I have my doubts on the config of the mustang dyno as well. I am sure everyone has their own idea's at this point and everyone's input is apperciated!:tiphat:

Edit 2: Dreamer, get a suspension and clean your engine bay!:happydance:

How long are you staying at PZ till? i might stop by

I'm not guessing, I was told this by my tuner who knows what he is doing and understands how the engine/boost works better than any of us. More air means more fuel means more energy. You said it yourself, you are looking for a target CFM...

Yes btw, that torque number looks off. I would expect something lower from the mustangdyne. More like 290.

I should be there most of the night, usually if we leave it is around 11 or 11.30.
RCZ, not sure, going to pick the car up now and look over everything and see how it looks and such. Oh, and of course drive it. :tup:

Enjoy man! we expect a review later.

Never!
I am just going to drive into the night. :p

Ur car looks amazing. How did you get the spot up front?

il just leave these here until Dreamer puts up better ones. These are from tonight.

Ah geez, my engine bay is sooo dirty. :( Guess that is the price to pay when you drive your car all day.
I know the guys who host Access Zero and we wanted to show off the two forced induction builds up front.

Forget cleaning it, you need a bigger engine bay and a V8. I know a nice Z06 Corvette for sale.

Goat's Eat Anything

I feel bad for that engine, never getting a bath :( and now Mr. Supercharger gets the same treatment :(

"Blah blah blah" is all I hear from you. :p

Amen to that, right on the money. Stop hunting for numbers and drive.

Actual dyno numbers are hocus pocus. They can be way out, and can vary due to numerous factors, and often operator. But they are a reliable method to check the success of your mods.

Before and after dynos using the same dyno is the best way to see what gains you have made. The total number can be way off but look at how much you gained and how you gained it.

Always try and use the same dyno for all your testing, change one thing at a time and this will help keep the margin of error as small as possible.

Goats eat anything......

The butt dyno is what matters. :D

hey dreamer what sizes are you using for your tires? Same as stock?

No, I put 275 up front and 305 on the rear, the maximum you can get on the stock sport wheels.

This is what I'm doing for my next set most likely.

How is the ride? Bulging didnt seem bad. Might go with that setup or 255/285

Bulge is minimal and the ride is very nice.
I would like to get slightly wider wheels, but still no plan on which ones exactly yet.

I would not switch from the stock. Those wheels are truly outstanding in looks. Some of the best looking rims I have seen from factory.

On second thoughts maybe some 22" spinners.......

This

I hear dreamer has a small bulge, but it rides nicely. Tags Edited
