New Motor Dyno 974hp Vortech YSI 23lbs Dynoed the Camaro's New Motor Still running a 347 9.8 to 1. Upped the Compression a little from 9.0 Added a bigger cam (239/243 .651 .652 110Lsa) , more focused towards Drag Only, Sent the PRC Heads in and had a max porting done still running the 2.02 Valves, Pulleyed the YSI down from a 3.0 to a 2.68 still running an 8 rib setup with a 8.25 lower. Rapped it to 6900rpms. Changed out from 2 in tank 255's to 2 intank 340's. Dynoed on a Dyno Jet at RWR Motorsports in Littleton Colorado. Numbers are corrected, I live in Colorado. Trq was not reading correctly so I have no trq reading.

-8an Supply, -10an Return, Aeromotive Fuel Pressure Regulator, Speed Inc Fuel Rails, MSD Boost a Pump, 60lb Injectors which I need to upgrade running 88% Duty Cycle, 1-340 intank on constant duty (for crusing), and 1-340 running off a toggle for when I decide to drive hard or heavy accelaration over 3k rpms. No Water Methonal, 91 Octane Pump Gas.
Probabley going to be ordering the 108lb high impedance injectors this week. And then going to covert it over to E85 and get a re-tune.

The car is running 60psi on the single 340 and 7opsi when the second pump is activated. So they do act more like 75lb injectors; but that is why I am ordering the 108's They were getting close to being maxed out 88% injector duty cycle is getting up there.

Nice result, but still baffles me how you guys get such a small belt to grip.
I got fucked off with my 12 rib slipping after a while and went cog. No slip.
What's the graph actually like ? It's a pretty big cam, has power peaked at 6900 or still climbing ?

I need to get back to the shop, I am going down there Wednesday. Rob, was having problems with his machine, the boost wasnt reading and the torgue wasnt reading and after three runs in a last attempt to get torgue to read and get a clean graph with torgue not looking like a heart beat on the graph; he told me it just isnt going to happen. So, hopefully Wednesday I can get the graphs from Rob. IMO It looks like it was still climbing at 6800rpms. I wanted the tuner to push it to 7200 rpms. But since we are already overspinning that YSI he wasnt really comfortable with doing that. But I am running a RMCR bracket and a Custom Colorado Performance tensnor and a gatorback belt with ahe Richard Racing Ultra Grip Pulley. The pulley isnt cheap 166.00 with shipping but works very well. I read the boost off of my Pillar guage for those of you who werent sure.

Thanks Man, It is awesome tell 160mph and then it sounds like the rear end is going to explode 
I have a feeling that it will be a th400 car here someday, and the 4.10's will be gone for some 3.30's or 3.10's. I can only afford so many cluth replacements.

Remember this is a corrected factory, due to me living in Colorado. You would have to ask the Tuner for more info. BLACKNITE. I was skeptical also, but he told me to have faith in him and he was right. But those injectors are getting pushed, I will be getting the 108lb injectors here in the next few weeks when I get back from Rocky Mountian Mustang Round Up.

I will never understand why people post "corrected" numbers. The car makes 803hp, that's why it can do it on 60# injectors. Even 803 I have a hard time believing, but maybe the 70psi does it?
The car would never make 97Xwhp in a million years.
How tight do u have ur belt?
Got a link for that pulley?
I'm having problems believing all of this

Is the ysi that much harder to spin than the t-trim? I have a 8 rib 2.85 reichard pulley and am running 15 lbs. boost and I don,t think the belt is slipping. Do you think with a 3.10 reichard pulley I could get 16/18 lbs out of the ysi without going to a cog.
