Posted this in the GTO section, though I would post here since alot dont look there

Well the day arrived yesterday when I left my GTO "Nellie" with my Tuner/Installer to put on the remaining pieces to the puzzle. To go with that monster Mega Death Cam (will finally breathe) we have Patriot LS6 Stage II 59cc Heads, a Fast 90mm intake manifold, 90mm Nick Williams throttle body, and the tune with the 150 shot. Assuming all goes well I should have the car back next week with close to 500rwhp NA and 600+ on the juice

Stock bottom end??? If so, I'd have a hard time believing you'll be at 500rwhp.. I've got about everything, but a different bottom end with an aggressive tune, i'm getting 471rwhp and 420 tq. I dont think the stock bottom will take the shot of nos too long at this high of hp! I havent been reading the forums for awhile, but I thought its a stretch pushing the stock LS1 block past the 500rwhp mark, and 600whp would just not be smart. Am i missing something? Awesome if you can, but help me out here!

I am pretty sure you won't hit 500rwhp either. You are using "off the shelf" parts. With a sheetmetal intake, vacuum pump, dry sump, electric water pump and some other small things you would have a better chance at having a "monster build".

I am definitely pushing the stock bottom end When it blows we go bigger. Monster build is a relative term I guess, but I could have used another word. Regardless I am pushing the car to see what I can get out of it. I will post info once the build is complete.

At my current power levels I am only 53rwhp short of where you currently are. I am not sure what cam or other boltons that you have, but I assume I will be picking up at the minimum 50rwhp as most see 20 or so from the Fast and 5-10 from the throttle body and 30-45 from the Heads. Not to mention that I will pull more power from the cam as well.

Just got some numbers in and video and graph to follow. I am pretty happy overall except I need a new clutch now, no worries already have the new Bird of Prey in and is being put in on Monday.

Now for the numbers
NA: 480rwhp 460tq
N20 592rwhp 681tq

The numbers are a little low as the car was being tuned at the same time and this was run 4 and 5. Overall pretty good! My tuner is letting it sit for a while and will dyno again.

I would love to see that graph. 460 at the wheels with the stock 346? What compression are you running?

I will post the graph and vids as soon as I get them from the tuner. He is putting in my new clutch and I should have the car back early next week I will call and ask him the compression.

11.1 is what I was told. I am sure Gunnar @ patriot would know for sure on an LS1.

Great numbers man! But how come you only gained 112rwhp from a 150 shot of nitrous?

stevegrizzle

he did gain 220 tq!

It is in this particular tune. We tuned AF ratio for perfect NA numbers. Since I only spray at the track I did not want to lose any HP by tuning for the Shot. The ideal AF ratio for n2o is 11.5 or so and we have it tuned rich around 10.8 so my NA numbers are good across the board. Does that make sense? Yeah it did pick up 221 TQ pretty sweet
