Default Dyno Numbers? Is something wrong?

Just got my car off the Dyno and my numbers are simply HORRIBLE! I had an APS Twin Kit on a few years back and dynoed at 560/605 with TORCO. I just fired up the car this year after its been sitting for 2years sold the Twins and my FAST intake and went H/C my mods are mostly to support the Turbo kit so I wont get into it: Custom blower pistons, stock displacement though, full exhaust, mezier WP, twin Walhboro in tank pumps, upgraded oil system to make sure turbos ran cooler, still have 10bolt but with 3.73, stock converter and Tranny but built stronger and a few other things I cant remember (Was built about 7 years ago) is a 01 SS. Anyway just give you some Idea with basically full boltons other than stock intake and stock TB now my Dyno came back 365hp and 404lbs? What the hell is that? Its Patriot stage III heads and a matching CAM. Is this normal or should they be much higher? If this is normal does anyone have the Trickflow 500hp Top end kit on? and what is your power cause im thinking of changing then.

When you say "stock intake" do you mean the **** *** ls1 intake? If so that could easily be 15-20rwhp+ on head/cam car.

You also said "blower pistons" which makes me think low compression which isn't going to help the numbers.

Do you have a dyno graph sheet?

I know they are lower compression pistons you are right I forgot. I think the engine was around 10:1 or a lil lower this was many years back. And Yes I had to put the stock LS1 intake back on after I sold the whole FAST setup. Do do you think these numbers are good for what the setup is worth?

10:1 compression is stock. My guess is your compression is anywhere between 8.5:1 to 9.5:1. Either way, you will be down on power with an n/a engine.

365rwhp on a 346 ls1 with stock intake and low compression pistons (through an automatic with 3.73 gears) sounds about right even with patriot heads (which are not that great) and cam. Unless your cam is huge (which I doubt seeing as how it was on a turbo car), those numbers are right.

Are you running a set of full length headers or stock exaust manifolds? It can't have that big of a cam in it if your still runnig a stock converter.

Well as long as that sounds about right, think im gonna have to use some sort of power adder then with the low compression maybe direct port?

Full SLP headers, Ypipe, and Catback. Sold the turbo headers with kit.

I think im gonna grab a 90mm FAST with that Zex Direct port kit that is made for it and start using the bottle. Is it as good as a blower on LS1?

well theres your problem

grab another intake, grab some dart/LS3/L92/AFR/Trick Flow heads - shave them to increase CR, NOS, UD Pulley, and you're set for NA/NOS combination.

Like I said been sitting for almost 2 years. I was asking $20k car was fully built and twins only 51k original miles didn't sell so started to part it out. Then fell back in love with it lol. I figure its paid for and cost me nothing to own basically so why sell it?

Think a wet Plate kit would be better than direct?
