The dyno can give altitude corrected crankshaft horsepower, too. That looks more realistic.

Assuming you have a tune to go with the mods, you might have managed 305 or so to the wheels, plus the parasitic losses of the drivetrain and you get into that 340 area.

So, did the dyno operator give you the printout, or not? If you can't present a piece of paper to read the fine print, I call BS.

considering autops put down around 225-230 stock 16 rwhp is a good jump for what i have done.

I don't even buy 341 flywheel HP. As you point out, it would indicate the car makes nearly 300rwhp which I just don't see with those mods.

If I were OP, I would take the car to a different dyno and/or take it to the 1/4 and see what it traps. That would be a reasonable reality check to see what range of power the car makes. Those mods are not likely to make more than 250rwhp.

unless it has a stroker/big-bore. i have seen a 5.3 big-bore stroker throw down 350 NA but it was 10:1 comp.

There is no way on God's green earth the OP's car, with a CAI, LTs, catback, and UDPs put out 305 rwHP.

And if still running the stock tune even 241 rwHP would be s stretch.

Also the OP's location say Florida, so the very highest above seal level he can possibly be is 330 ft, more like 10 to 15 ft.

Agreed bc with catted x, 10series flows and cai I put down 233rwhp/266rwtq so thats about right when you slap it on the dyno instead of the guesstimate type numbers.
