I don't have a scan of it yet but will get it on here soon.

The results are:

HorsePower - 358.07

Torque - 414.53

GAS: Sunoco 94 Octane

Conditions:

66.02 F
29.37 in-Hg
Humidity: 19%
Correction: STD 1.01


I was just checking out some of the other dynos. I wonder why my HP is so damn low compared to some of the other guys?

There were two us of this morning who dynoed at the same dyno. It was a DynoJet btw. He even got lower numbers then me and he was on 98% as well.

We did do some data logging so we'll post those as well soon. The PSI was stable, did not even go above 14.1 or 14.2 can't remember.

Marvtec's #'s were

HP - 342
TQ - 370

Can't remember exactly but he can correct me if I'm wrong about his #'s.

On what gas?

What doesn't anyone post SAE numbers?

Just edited the post and included it.

What's the difference between SAE and STD?

From what I have been told standard will give you roughly ~2.6% higher numbers. That is why most people (including tuners) use that to talk about their numbers.....

Why 98% on 94 octane when the recommened stop point is 94%?

Where did you hear that 94% was for 94 Octane?

Shiv has said before you could run 100% across the board w.o running race fuel

[zenmaster]

Octane requirements have to do with your effective compression ratio, which is dependent on its absolute manifold boost pressure. Across cars, the user torque settings simply don't map to same absolute manifold boost pressure. Obviously, there is a problem with reading or controlling/maintaining a certain (absolute boost pressure.) Get a boost gauge or sample log and determine what you're running - not "Shiv said"!

Maybe if one is at 8000' above sea level. And even that would be a special case. Other than that, the recommended stop point is 94% on pump gas. Even on 94oct, I'd stay below 95%. And if you are running the stock intake box, there is certainly no reason to run it higher because you will reach a choke point at ~350whp. Regardless of exhaust mods or boost level.

He said 93, but I took it as meaning top of the line pump gas.

"93oct guys should stop here at 94%." - Shiv

In addition the base settings are 90% and you are only supposed to bump them up 2% at a time.

And here:

http://216.120.252.228/forum/showthread.php?t=348

" Do this by adding just 2% across the board (at all engine speeds). After this adjustment, measure boost by conducting the same full throttle tests. If the desired boost pressure is still not achieved, you can add another 2%. And test again. To make fine adjustments to peak boost pressure, 1% increments (in either direction) can be made. To achieve the maximum allowable 14.5-15psi at 5500RPM, you may ultimately end up with 92% across the board. Maybe as high as 94%. This is normal. Do NOT arbitrarily set all values to 100%. This is bad. It can cause engine damage."

Hey Shiv,

Both of us have stock intake and exhaust.

Thanks for your comment. Just so that I understand this correctly I shouldn't run 98% if I'm on 94 Octane Pump Gas?

What exactly do I need to do to keep it at 98%? get intake and exhaust?

It would be pretty hard to get higher octane gas for regular every day use. I'm kind of addicted to keeping it at 98% since I've seen the difference.

Thanks for your help.

Race gas - "It is perfectly acceptable to run high octane race fuels (Unleaded only!) with your PROcede. Mixing pump and race gas is also fine. Doing so will result in high power output and improved engine response. When running a higher octane race gas mixture, is also possible to raise boost pressures beyond the 14.5-15psi maximum pressure specified above. Additional instructions will be provided for doing just that in due time. For now, however, do not exceed the suggested boost limit."

You have to adjust the settings gradually while using datalogging to check out how things are running. Shiv said setting at 100% is bad and can cause engine damage. 98% isn't too far from that. I would back it down to 94% and create some logs at that level.

Correct. Do not run 98% with pump gas. Even your 94oct. You will get knock retard activity. You will probably see this in your dyno graphs as they will lack smoothness or repeatability.

What you need to run more than 95% is race gas. Plain and simple. 100oct is a good choice. Still, on an otherwise stock car, you'll still be limited to ~350-360whp due to intake restrictions. By simply using cone air filters (coming soon), your power will jump up to ~380whp. An exhaust will give you another 10whp or so.

Try to force power by raising User Torque is a bad idea. You will put undue stress on your turbos as well as induced knock activity. Which will lower power. The opposite effect of what you are trying to do.

This is why we suggest sticking to the 94% maximum on premium grade pump gas. It's safe and will result in good stable power. Same applies when you get an intake and exhaust. The max numbers will just be higher.

Shiv

PS. I'm reading about too many people running too higher of User Torque on pump gas and it is making me very nervous. Come on guys. Please be careful and follow the documentation.

[djrobroe]

yea cuz in the end when you have blown motors these are the same individuals that'll say ProCEDE blew my motor this and that.... that's how it always goes... people need to follow instructions...

[Ado]

I've never heard that info but thanks for sharing Shiv.

With regards to your comment about knock and smoothness of the curve on the graph: It's actually never been smoother before. I've used the same dyno every time on the same configurations. I'll upload the graph soon along with the data logs. We were also listening in for knock on 95% and 98% and have not heard anything. The guy that helped us out with all the stuff isn't new to turbos http://www.splitfireperformance.com/splitfire_high.html.

Thanks for your help.

Why don't you make 94% = 100 so that people who like to push the envelope know exactly that, they are pushing it?

If you run 95%, people will argue they thought they were still on the safe side. If you make it 101 or 102%, they will have a hard time arguing they did not realize.

Actually, that will + or - match the octane needed to run those settings.

[chris b.]

what if at 94% you still have not achieved 15 psi?

As shiv mentioned, 95% and above only with race gas (100 octane). It's an option for those who bring their cars to race track regularly.
