Smile In shock...474hp at the dyno

Just had my car dynoed with a DynoJet 248c. I did this as a "before baseline" prior to installing the mods.(as we speak). 474 was best and 461 worst (heat soaked). This with stock programming EVO V-flow and Europipes. HP is altitude adjusted (SAE). I am in shock. Also my Mechanic (Orrin...thanks much) says it was running lean (there was more there). I will get the sheets when I pick up the car Friday and post.

That's amazing with the stock programming. Good for you.

What that means is that Dynojet numbers are far more optimistic than a brake engine dyno or a MAHA dyno used by the German tuners.

Wait this is at the wheels??? Even at the engine that number is amazing for just an intake and exhaust.... Please clarify if that is rwhp/awhp or engine, either way its quite high!

Wow, that is more than Stage 2's make!! My stage 2 made one of the highest numbers in the country @ 468 (uncorrected and on a dyno that reads much less than a dyno jet, but still), unreal that your stock programing made more! Dynojets do read higher, but that just crazy!

This number at the rear wheels with stock program, k16's, intake and muffler? That sounds unbelievable.

What does a stock tt put to the rear wheels 360?
So muffler and intake added over 100rwhp?

Please clarify

Even with k24's your still talking about an additional 100 rwhp from just a intake and muffler, that sounds impossible or this car is a freak

With a correction factor of 12.5%, the 474 RWHP means a crank horsepower of over 541... With just the V-Flow and EP exhaust??

Somethings not right here...
