$108 per Horse, good deal......

So I was off 30RWHP

I guess you need the new pulley as well?

JB-370z · 07-23-2010, 03:04 PM

HAHA I totally understand but in the world of VQ motors this does not apply for some reason, and ask any of the 350z guys...They don't know as well! But it is known that high flow headers lowers the boost! That Mustang of yours running good? You should bring it out to one of our many outings

He isnt losing PSI from it being a VQ motor. He is losing it because of other factors.

The Kit was designed for a Stock 370z with stock exhaust therefor they made a pulley that produced 8 lbs for a stock 370z.

His car has very free flowing exhaust (due to the long tube headers and berk cat back, and lack of cats) which makes it much more efficient so it will take a different pulley and tune in order to get the 8lbs of boost.

So what needs to happen is he needs to get about a 10-12lb pulley and re tune.

I would love to bring the stang out it runs great! I would love to see your car and others that Matt and I have talked about, however I have a pregnant wife at home so getting out isnt as easy anymore!

I got it a long time ago.

Caravanshaka · 07-23-2010, 03:14 PM

he's not making MORE power with Less boost thought. He is making more power at the same level of boost than he would with stock exhaust though.

Basically. His efficient setup causes that pulley to only push 5.5 lbs of boost. If he replaced his exhaust with stock components, he would make 8 lbs of boost, and would make more power than his current setup. HOWEVER, if he gets his current setup up to 8 lbs of boost by way of a new pulley, he will make MORE power than the 8 lbs of boost did with stock exhaust.

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.

Chriz · 07-23-2010, 04:55 PM

Awesome. Cant wait for new results

RCZ · 07-23-2010, 05:14 PM

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.

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

theDreamer · 07-23-2010, 06:08 PM

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.

JB-370z · 07-23-2010, 07:18 PM

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

LiquidZ · 07-23-2010, 08:41 PM

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.

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.
