Default Stock internal LS1 N/A H.P. record breaker?

So after much work my car finally had its day on the dyno. Nothing that touches oil has been touched. Car has 2 tunes, 1 for 93 and 1 for E85.

Car is a 1999 Camaro SS M6.

Engine Mods:
FAST 4150
Vic Junior intake
60lb injectors
Jegs UDP
eBay stainless steel long tubes (wrapped)
Texas Speed true dual exhaust

Tuned by Justin at Gulf Coast Motor Works in Naples, FL.

Stock 6 speed trans. 4.10 gears. 10 bolt.

Here is the dyno graph of the car. The higher of the 2 is the E85 tune. This is a dynojet dyno.


Std correction numbers:
393.86hp 378.64 tq

Is this a record breaker? We should start a list to keep track.

No I bought the car not running from a guy in Ohio. I stripped it down. And completely rebuilt it. I pulled the motor that is in it out of another Z28 vert i had. It had factory everything on it down to the factory lid and exhaust. it was bone stock. I will post pics up tomorrow.

Ok, maybe I missed it somewhere or reading wrong, but was that 393/378 done on the stock cam?

Those are the corrected numbers. What it did on the dyno is on the graph. But from what I understand, in a perfect world it would make 393.

Bone stock LS1. No heads, no cam, no built bottom end no nothing.

The reason I asked, is I have a friend that had a similar situation, bought a used camaro SS way back in 02 , thought it was stone stock, from a lady 2 boot, stock exhaust manifolds etc, He did every bolt on, and had decent #'s, then recently went internal and low and behold, apparently it already had a Lunati cam in it..

That's crazy. Well as far as I know, this one is bone stock.

Anyone know what the highest recorded LS1 HP n/a is? I would like to know to compare.

98blueSS-
The engine and made its peak hp on gasoline with the advance at 29.5degrees at the peak hp point.

On e85, it made its peak hp at 26*. However both tunes put more timing to the motor below that point, as I tune for mbt at every rpm point and don't just block out the entire wot region of the map with one number.

Another interesting tidbit about the e85tune.. It made similar power numbers all the way to 34* at peak hp with absolutely no knock. The power was slightly down, but the knock sensors were happy. Just shows the resistance to detonation that fuel offers.

Hmmm, the torque at the low end almost looks hot cam-ish. The power curve vs. RPM looks stock cam-ish. Those injectors look monster for a stock motor, would love to see the duty cycle on those. I think the idea of "straightening" the intake tract along with opening the exhaust with headers and duals is super interesting. Would REALLY LOVE to see a video with high quality sound of this car idling. I think THAT would be the tell tale. IF this car had a cam "snuck" in by a previous owner, it's one helluva stealthy torque monster. Regardless, these are impressive numbers and I wouldn't bother keeping the E85 tune given how close the results are (which also supports that it's a stock cam, to me). Why give up the MPGs for such a small increase in HP? Nice work! Now get us an idle vid!

Yeah i running E85 with 12.3.1 on an SBE h/c/i setup and it's peak hp is at about 28 to 29*. going to try and move timing up at the track and see what it will do. but as for E85 and knock its the best fuel for a high hp Sbe. i never see knock and i d/d mine in the summer in traffic and all while traping 130+ at the track.

We saw IDC's at WOT and peak consumption of about 50-55% iirc

Ask and you shall recieve, see below

Why give up the MPGs for such a small increase in HP? Because he plans to hit it with a 200hp shot of N2O, and the E85 will drastically benefit him then
Nice work! Now get us an idle vid!


And just for *****... Here's a comparison of this car and a full bolt-on 2001 one owner car that came into my shop last year. It was an auto and the weather conditions were obviously different, but you can see the difference the intake made over an LS6 with ported TB.



The lower HP car was a verifiable stock cam, one owner car.

Lastly, the dyno vid:

Damn! Thanks JD! Have you had a chance to dyno the same car on your dyno and someone else's to see how it compares? That stalled auto comparison car is stout as hell too! Nice work and thanks again for the vids and extra graphs!
