+110wHp with Gintani Headers, Exhaust & Tune
I finally dynoed my car today after installing Gintani headers. All of the same conditions were followed. CA91 pump gas from Chevron, same tires, etc. Dynodynamics Dyno. The gains to the wheel, peak to peak were +110wHp & +83.7wTq, when comparing the baseline with no mods to my current setup.
Current setup: Gintani Headers with Full Gintani catless exhaust system, OE Tuning Stage2 ECU tune, AFE dry filters with charcoal filters removed.
+30wHp was seen over my last results (stock headers, Gintani Exhaust & Tune).
I also had the chance to film the car running on the street, out-of-car viewing the exhaust tips while driving.

Dynojet numbers to come.

Congrats, Jeremy! The power looks great, especially the torque. Very impressive for sure.
Can't wait to see how fast she is when you get to the track.
Btw, do you have the LSD in? Just curious cause I was wondering if both wheels were spinning when you broke the tires loose in the vid. That was cool, btw.
Also, I like the idea of using the AFE dry filters. If they work alright for you, I think I may give them a try next go around.

I'm sorry, I am confused.
So basically you got 130+ hp from full exhaust and tune? On a normally aspirated engine?
To get that rear wheel hp number the car would be making around 590 HP at the crank right?
Wow.
Isn't that a lot from exhaust and a tune on a normally aspirated engine?
What does Dads C63 make?

what ever number it makes to the wheel divide that by .82 (18% drive train loss) and you get you fly wheel HP.
for ex 470/.82=573 but dont forget this is a DD dyno so it reads lower.
its not alot of power, from a tune and header only car you get 95rw-100rw this is with the full exhaust so the numbers look rite

Depends on the DD. Some (most?) read lower than DJ, but some DDs read roughly the same, or even higher. What's important to see are the deltas between the various levels, for relative comparison; this does a good job of showing them all together, IMHO.
Agreed that the numbers look right, for a full header-back exhaust system with a matched tune.

From my math his car on a DJ should pump up around 485-490rw sae

The good news is, the OP mentioned "dynojet results coming soon" - so we won't need to guess for long.

IMHO, you can't really compare your cars results thousands of miles away, different dyno types, locations, operators, etc... and then attempt to conclude what his car would achieve on a DJ. The octane difference alone (93 for you, 91 for him) could account for a percent or two variation between your respective results. A percent or two at 500 whp is 5-10 whp.
