Post Dyno Graphs 4 Tunes, I/C, Exhaust, Etc...

Okay Folks,
For the sake of bragging rights letís start a dyno thread for modifications for the 2.0t. It would be very nice to see side by side comparisons for all the new tunes coming out, exhaust gains, intake gains, turbo upgrade gains, etcÖ

Donít forget to list your mods along with an explanation!

2008 Black/Black GXP, purchased 7/23 right off the train.
Mod#1 blacked-out headlights
Mod#2 GMPP Intake -I like to hear my turbo.
Mod#3 Special Sauce (23PSI)
Mod#4 Solo Street Race
Mod#5 Repaint w/ Custom Silver Stripes
'07 Charger R/T Mama's car

I’ll start PCM for Less since Bryan is doing some stuff for me.

Horsepower increase to 317HP (crank)
Torque increase to 332 Ft/lbs (at the rear wheels)
Top speed limiter increased
Boost raised to 22/23 LB with air/fuel changed to run safely at that boost level
Valve timing changed to bring in boost faster with a fast spool up to max boost
Torque management backed off for better launches




These numbers were from a stock car

Odd graph. Why did they only show a 2850rpm window? Is the power done by 5600rpm?

My very first dyno run from June 2007, the first Westers tune for a Solstice GXP.

My most recent run, not the tune I am running now, but the last one I Dyno'd it is a HP vs AFR not TQ

These are on an eddy current Dyno Dynamics Dyno, they tend to run well below Mustangs and Dynojet, he used a 9% compensation, I think maybe 11% would be better from what I have seen, just this dyno shop tends to be very conservative. They dyno'd a stock GXP at about 216.

Solo Mach and No Cat custom A/R cone
Dejon Intercooler, Intake Elbow, BOV spring
Wester's Garage tune
RMR Style Bar.
SSR Type C wheels, Nitto 555's
DDM Works PINK Breastplate, PRO Beam
HKS Coilovers
GXP Z0K rear sway bar with urethane bushings
Custom Jonymac glass wind screen, one of a kind.
Eclipse AVN726e; ZED Audio Leviathan, Image Dynamics tweeters, CTS door subs, active crossover tri-amped. Audio Control 6 channel 30 band parametric EQ.
JL Audio 10" sub

I think it is more than that now but Lyndon told me not to dyno the tune I am running because he has a new one coming soon. (when you and I go home and watch TV, he plays with ECM code)

When he did my first tune he had never seen a GXP, just adjusted what he could based on a best guess, 262 wasn't bad for a first try.

Just understand when you are looking at the figures you most take into account what other mods the car has, since that will have a significant change in the numbers.
A car with ALL stock hardware and a tune will have different figures to the same car with Exhaust system, intercooler etc.
Also the type of Dyno gives different results.

Aggressive GXP at $25,995.00 shipping of $600, MT.
Options:
Air, $960; Chrome Wheels, $545; PCQ, Premium Package (Leather), $525; Radio, 6-Disc with MP3, $495; Monsoon, $395; Premium Acoustic Headliner, $150; and Sport Metallic Pedals, $115; all totals $29,180.00.
No XM/OnStar and NO Spoiler.

MODS (Magnaflow 2.5", BTF Turbo Upgrade wheel,DDM BB,ProBean&tune, Vntrshield, LVKFCB, JPM.
First 1000. Aggressive with everything, NO XM/OnStar. SOLD

The biggest issue with comparisons like these is the variance in dyno's, I have seen my car dyno 10 rwhp less on the same dyno with no changes to the car just because of weather. Eddy current dyno's are very accurate, and give lower results than inertia (roller drum) dyno's but they are not nearly as consistant. You can repeat results on a Dynojet pretty well, not nearly as easy on Dyno Dynamics. I also learned that the GXP heat soaks very quickly, and usually the second pull will give the best numbers. I am sure it has to do with heat, turbo does better warm but not hot.

Amazing nose dive power takes after 5500 rpm on all these graphs. We need a bigger turbo.

You are right bro!

Bigger turbo and a standalone engine management!

Actually if you look at mine, the dyno operator stopped recording at 5700 and the HP was still up there. I need to go back and get him to push it to the redline (7400) I'd like to know where my power fall off.

Hopefully the larger wheel with the power management settings out of the way, it will show a good increase past 5500 RPM.
