802SHO 2010 Build

[mybigsho]

MybigSHO I was tuned to 18 psi last year on stock turbos and I believe some go 19 maybe even 20psi stock...working the stock turbos very hard but they handle it.  The newer the stock turbos the longer they'll last at that psi.

Thanks.. I thought i was seeing 19psi in some data..

My 100 octane tune hits 18.5-19psi on stock turbos

For reference.. here is the datalog from the dyno pull...

My Revision 4 with Meth is very close.  Thank you for the reference.  I'm excited for my dyno day June 13th

Yours was a mustang dyno too right?

Yours was a mustang dyno too right?

No, It was a dynojet.

Dynojet is better yes?

I wouldn't say they are better.  For power pulls the industry tends to revolve around Dynojet numbers. Mustang, Dynodynamics, etc are all different brands that different shops use. Mustang dynos are also referred to as "heart breakers" because they read really low. But they are supposed to be fantastic for tuning.

Yes I think I've heard that before.  It's too bad I didn't know of this shop before so I won't have anything to compare my numbers to....like for instance even if it were to read low or high, the difference in power made from one tune to the next would be undeniable. 

I think so long as my car runs really strong and feels better than ever, I won't get obsessed with dyno numbers.  In the future at least now if I add more things I can go back to this dyno and see how much I gain.

Yup, dyno print outs tell a story.. hows the torque curve look, how does the afr's look, is the curve what is expected, is the power delivery smooth, etc etc etc...  For comparison between major upgrades a before and after comparison is very nice as well. But for just a peak HP/TQ reference, not much weight behind that. AND the same car on the same dyno can put down different numbers on different days, even after corrections. Corrections are not perfect either.. and they don't take into account ECU cutting power due to IAT's, coolant temps, etc..

If you do three pulls and the power delivery smooth, curves looks right, etc.. then you should be happy with that.

Yeah that makes sense.  And I should keep have them do a 4th gear pull right?  Ive never done this before

Up to you, I have had them done in 4th and 3rd... 4th is closer to 1:1 so most shops want to go as close to that as possible. However, in the SHO world, 3rd tends to be standard.

SBS is right don't get set on hitting a certain number on a dyno. Its all about power and torque curves. Also usable power. My old car would only do 450-470whp on a mustang. I would walk all over cars that did over 500who on the same dyno. They tuned for a peak number. I tuned for a flat usable power curve.

Good to know fellas I feel much better knowing what to be truly concerned about and what to look for.

So here is a comparison...

The higher number was the pull right after the turbo's were installed.. car was driven around for a short drive to warm up the components, then dropped on the dyno... the lower number is after I drove for 2hr's down interstate 95 in traffic, then dropped on the dyno.. it was also much hotter and more humid that day as well..

The peak numbers are different, but look at the curves.. they are identical. So what this tells me is the car was running exactly the same both days, but either I was pulling power the whole time from heat soak (which it was) or the DYNO was calibrated slightly different that day as well resulting in a slightly lower output. However, the point stands that the curves are IDENTICAL but peak is is off by a couple percentage points.
