It would be more helpful to see the before and after dyno graphs.

Are both dyno results on the same dyno?

are you on a flex fuel kit or on a straight e85 tune?

@thebug44 has a build thread where he is using Eurocharged and an AFD flex fuel kit. he might be able to shine some light on your results.

I don’t have any dyno numbers unfortunately. Just some runs at the track.

ran 11.2 at 123 I am actually looking for a local dyno to do some pulls just to see what the car is making.

Drag times and trap speed are more accurate indication of power/torque than dyno figures.
Every dyno reads differently and some shops like to inflate figures to make their work look better.

well, I put 3850 (i have no idea what my exact car weighs) as the weight and the fastest trap from my track day was 124mph so it came out to 572.90 HP not sure how crazy or not that sounds.

although an online calculator should only be used for entertainment, I'd take a guess that was referencing crank HP. additionally, peak hp is something EC tends to produce due to large amounts of ignition timing involved.

A tune and long tube headers was often assumed to come out at about 570 hp at the engine, give or take. So that equates to 120 hp at the engine and about 100 hp at the wheels. Depending on the state of your tune and E85 572.9 bhp is a reasonable estimate for your car but perhaps as much as 20 bhp on the low side.

Every car is different

Can never compare the same 2 cars

Your intake manifold could be full of oil and you could be losing power

Your car seems to be moving alright based on times and mph strip it and try run low low 11s

but the internet loves bench racing. lets all push to 505whp with a 1.10 correction factor and ask how it was done.

that’s good to know. I am just running a standard flash tune so hopefully when Barry tunes my car I’ll be running faster times at the track.

Their tuner uses proper STD correction (no funny business) instead of the industry standard SAE. Gets the sales though. So many FB posts with 500WHP and simple bolt-ons.

Actually, one that comes to mind had port and polished heads but the math worked out to ~480WHP SAE corrected.
