My DP setup...what you think? i baught a fast 90mm intake with a DP kit on it from a member on the boards here. i installed everything on the car and i drilled and tapped the bracket on my fuel rail so i could bolt my solenoid brackets to them. its not the cleanest setup i know but i think it will work very well. i dont have the nitrous feed line hooked up yet and i have to do some finish wiring but you get the idea.
what you guys think?

well im shooting a 200 rwhp shot using .026 nitrous jets and .014 fuel jets on all 8 nozzles. as for fuel system i have a racetronix 255 fuel pump and hotwire kit and running 30# svo injectors. I am also running a fuel saftey switch set at 47 lbs so if i do loose fuel i should be ok.
99.9 percent sure your fuel system is not going to support it after looking at your mod list..
When the fuel solenoid opens it demands a sudden flow of fuel. It drains the rails for a split second causeing a lean condition upon activation. The fact that the fuel system is being worked so hard it will struggle to regain pressure..
Save your self some headache and either put a dual tank set up in the car or put a deadicated fuel system in.

well to be honest that sucks lol. i saw you write on another page that the racetronix kit is good to 650 rwhp...i should be right on that border so i think i will give it a shot on the dyno and see what it does first before going to the track.
I would not tear into the tank again so my only option is your plastic dedicated tank which is an awesome setup but it does cost some coin. is that tank setup to output the same fuel pressure as the ls1s...58 lbs?
thanks

Yea, But 650 hp on a plate or a single nozzle is night and day differnec compared to a directport. With a plate or nozzle you are filling a smaller area before the system can catch up. With a directport you have to fill the block and all those lines to each nozzle. So the shock on the system is harder.
If you go with a dedicated ours can do high or low pressure but I would swap your set up to a 10 psi tune up. It will make tuning alot easier. With the high pressure the fuel pill orfice size is very small. And if you have to lean it out buy going to a smaller jet it gets even smaller. A grain of salt could clog it its so small.
By going to a low pressure your jet size would go from a 14 thousands jet to a 20 thousands for the starting point. You can make small fine tuning adjustments by the regulator on the dedicated instead of having to do a jet change.
Now big changes need to be done with a jet change for either set up though.
If you have to pay for dyno time and you get there and do not have enough fuel system you just chunked that money down the drain. Now if you have the hook up for dyno time thats not so bad then... Just watch that fuel pressure gauge.

thanks for the info dave. the car has to go in for the N/A tune regardless so im going to let him do that then im going to pull the timing and see what she will do. if i have issues then i will see where to go from there
thanks again
thanks again
Why go DP if you only plan to spray 200? You could easily spray 200 with a plate or nozle. Your set up will work for sure but for some reason it just doesn't have the WOW factor most DP systems do.
good luck on the fuel issue.

thanks again dave
the reason i went DP is i got a sick deal on this intake with the dp already on it including all Noids and jets. the motor is forged and built to handle a 300+ shot so i also got it incase i wana go crazy and go for deep single digits lol.

I've got a fuel accumulator off the Cal Speed DP I bought. Nitrous Outlet built the system. I'm not using it for my build as I am going dedicated fuel system. Pay me for shipping and you can have it.

We might have built the system ( Nitrous System ) but the accumulator is a Nitorus Express part.
