It is also the G5XB camshaft. I will try and find someone to video it. My videographer is at a internship in California right now.

I would look into the Cobrajet 80# injectors (made by Siemens Deka). Greg Banish mentioned that the ZR1 injectors don't have a spray pattern that cooperates well with LS3 heads, since the port design of the LS9 has different geometry, they end up just spraying down the wall of the port instead of the back of the valve.

I'd be curious to see the duty cycle and rail pressure that thing's doing! That's a damn lot of power.

Awesome numbers!

Matt, lunch?

hello everyone
the car in this thread is mine, cant wait to pick it up from rmcr!!!
i will try and post some video maybe this weekend if mike doesnt get
a chance.

being in the automotive retail\wholesale business,it is hard sometimes to find someone with the great customer svc that mike has! when you meet him in person you know your car is in the right hands! its worth the trip to colo!!

thanks mike see you this weekend!!

If there is a stock pump on it i would be careful and watch the pressure drop during the run but im sure your doing that already.

I think the SLP headers are holding it back. The ARH 1 7/8's I think it would of broke 700 RWHP.

Impressive numbers, I've not dyno'ed mine yet but I am very happy with the Kooks 2" headers and full 3" catback. Sounds wicked.

[Mike@RMCR]

Rail Pressure was holding @ 55 PSI and the Duty cycle is @ 85 %. I think at the altitude were this car is going to live in the 6500 to 10000 feet range we will be fine. Sea level or extreme racing I would recommend a dual fuel pump set up.

These are SAE corrected #'s so uncorrected # is less. Also this is with a V-3 Si Trim 1150 CFM.

[GQ4Life]

Oh ok. That why no pump needed. at your altitude your at maybe 560wHp to 580wHP so pump just running out but SAE corrects for altitude so if you were at sea level it would be 680wHP..
what is your altitude?

[BLWN SS]

It depends on the day but in Colorado Springs we are at roughly 6000 feet physically- We see the DA go over 10,000 regularly during the summer. Its so dam bad here its not uncommon to re-jet a carburetor several times in a day at Bandimere Speedway.

yea when i looked at altitude I was guessing that you were definately over 5000feet to lose that kind of HP...
at that altitude and DA your stock camaro would of been slower then when my SRT4 was stock..
dude id move..
I thought my stock camaro ss was slow here at about sea level..
I was mad that the track near me was at 608ft and when I ran the DA was 1403..
I feel bad for you man..

[Mike@RMCR]

I have never seen a DA lower than 7500 feet in the springs. It is normally in the 8k range. I think that is why Nascar and Indycar pulled out from the speedway here.

[GQ4Life]

I dont think I could live there when my 13 flat car can only run 15..

The actual altitude at RMCR's shop is about 6300 ft.

Mike, is that cam you put in, the same one that is in the black LS3 Corvette that is always parked in your shop?

being a gearhead and not the worlds best av nerd, i took video of the car at idle and a clip with some revs. i did it with my cell and emailed to myself,and cant upload the quicktime file to the thread. i can run it on my laptop, but thats it. any help would be grateful?!

if you thought your car was fun naturally aspirated wait til you go vortech!
everyday driving is pretty much the same with just a hint of kickass, but when you hit the on ramp to i-70 OH MY FRICKIN GOD!! YOUR DOING
120MPH IN A HEARTBEAT!

mike/mark at RMCR did a top notch job, i am glad they had me do the bmr
rear suspension upgrade so i stay hooked up!

i will forward the clips in an email to any one so you can hear how it sounds
just pm me happy motoring

thanks again RMCR
