Default Whats your Hp Be honest!

I'm not posting mine cause I'm gonna name the mods and additives on my last dyno run and tell me what you think it was. If you have close to the same mods tell me yours. Guys from PT.Net and LS1tech where there and in shock to see my numbers.

Mods during Dyno Run:

Pacesetter Lt & ORY
K&N 77Series
Flowmaster 40 series dual out
T/B bypass( like this really matters alot)
Stock 3.42 gears

Fuel/Additives:

93* 1/2 tank(about 12gals)
Lucas Oil octane booster

What type of dyno?

I dynoed mine with similar mods and did 260hp in 2nd gear on a Dynojest so that was probably more like 275 in 3rd.

So my guess would be in the 265-275 range.

362.4 HP @ 6271 rpm
374.8 TQ @ 5480 rpm
on a SuperFlow Dyno. Add about 10% for DynoJet equivalent.

Why did you dyno in 4th gear? Usually dynos are done in what ever gear is 1:1 which with our auto is 3rd. Or 2nd gear if the speed limiter kicks in like mine did but that will give low results. Since you are untuned you must have hit the speed limiter pretty low in the rpm range. I know in 3rd I hit it at about 4100 rpm with 3.73s, so in 4th with 3.42s you probably hit it a lot sooner.

Makes no sense to me.
