Well if it’s a Dynojet it’s very comparable actually.

Forgot to update after the fuel pump upgrade . It ended up at 548whp 444wtq. It carried out to 7800rpm now with out running out of fuel. I wanted to try a few things that woulda likely helped power a little but the starter went out on the dyno and used up my time fixing it.

Given the well above average results could we get the SAE graph with weather data for these pulls?

hot and humid August weather. Typical for this area and time of year.

It's not well above average. There's been lots of 5.7s over 500whp. The used cam came out of another 5.7 that made 538whp. Typical h/c car picks up 100~whp or so. The bolt on ls6 made 451whp. This is the ls6 just a mild rebuild and h/c......and it picked up 100~whp. Falls perfectly in line.

This is very high for a built 347. Post it with weather data.

480 rwhp here on top of a built LS2 with home ported 799 heads. This was on a HEAETBREAKER 48 inch drum that tends to read lower than most dynos. Hydraulic roller, heavy flywheel, stock water pump and a stock size underdrive pulley.

Decent results tusky. Probably wouldn't be hard to squeeze another 20-30 out of it. I think I learned a couple things on this build that seemed to make for good results.

I told you what the weather was. Several times.....what's so hard to understand about it? Typically suspicious people that questions decent results are not very honest about their own.

We could have done a light flywheel, electric water pump and an under drive pulley and no doubt made over 500 with Tusky's. As far as Hios 's awesome numbers and other high HP 5.7s it's not hard to see why they make that power they do Just look at the rpm it turns , basically it's cammed for it. You are not going to make that power with an average cam that peaks at 6-6500.
He has his cammed right, attention to detail on everything , leave nothing on the table. It's expensive but doable.
This is why it appears to be above average results, most people don't spend the money or attention to details to get those extra hp.

This is the weather data I asked for.

Thanks....I agree for the most part but realistically the cam isn't that big. Hell looking at cams some are installing these days it's even on the small side. I think the msd intake is a better choice overall which allows a bit more rpm. Darthv8r tested both with this cam and got me headed in the right direction on his h/c ls1.

I certainly think Tusky's could make more power and i would love to see him go after it.

I have told you several times it's not on the dyno sheet. The dyno sheet has been posted for you to not see it on. Therefore I answered the weather data for you. Dynos were in june and August. Typically hot and humid . Definitely aren't getting any good days for making power that time of year around here.

Now.....how many more times are you gonna ask the same stupid question that I already answered?

Get a dyno sheet with it on it. Pretty simple.

I have a dyno sheet. I have posted dyno sheet. Weather data is not on dyno sheet....as I have said multiple times. They didn't give me one where we ran it out to 7800........and I prefer that one.

Do you have anymore nonsense to add?

You don't get it genius! His dyno doesn't do that. It's HIS dyno report. He owes you NADA.

It is not that hard. You simply request the 7800 pull with the weather data.

The fact that you refuse to do so makes it seem like you are trying to hide something.

You don’t know what “his dyno” does or doesn’t do.

So please move along with your uninformed opinions.

HE knows what his dyno can or can't do. IF his dyno does what you are asking, and IF Hio wanted to show it, you would see it here.
Learn to be more observant than you are. He'll tell you what he wants you to know. You aren't in a demanding position.

Not ignorance, you moron. It's Hio telling you what he wants to tell you. I don't know for sure, but I doubt he gives a flying **** what you want to see.
I bet he's fed up with dealing with you. I would be too.
IF all Dynojets are the same, then you have your answer.
BTW, I fixed your grammar above. It's good to be educated....
I also noticed all 7 of your posts here are in this thread. Are you trolling the OP??
