Sup people , i just came from the dyno and we had some problem before with the solenoids pulsing etc... I think the relays isn't getting an good ground from the DFI . Both stages was pulsing dry and wet . I put 225 shot nitrous but i gained around 180 rwhp . I didn't use the nitrous option from the DFI cause it was giving me some trouble . I just raise the VE table on the fuel table when i'm at WOT to make it rich to compesate the dry shot . I have the dyno sheet but i have to take pic of it and upload it . I didn't gain much torque cause i activate the wet shot before and the the VE table being very rich for the dry and when i activate the dry shot it make the a/f ratio flat ( 11.8 a/f ratio ) . This was with around 8 degrees timing retard i think it is too much timing retard . The dyno guy told me i should get atleast 425 with those same jetting but i told him that 400 +rwhp was my goal and i already was like 3 hours there so i was tired too . Now i should get 11s easy with this 404rwhp/435.6 rwtq . I will post the dyno sheet later .

Nice Numbers. Now all you have to worry about is if it will all stay together for another run down the 1320.

i think he ll be fine for the 1/4, very nice numbers. just curious shouldn t your TQ be a little higher though wasn't it around 420ish i think with the 150 shot. in anycase nice numbers though:thumbup:

Yeah , the torque number is low . There is 2 reason because it is low . Its because i use a 2 stage setup so it isn't getting all the nitrous all at once in the lower rpm and because i had the fual table set very very rich to compasate for the dry shot . The problem is that i hadn't use the dry for first stage i used it for second stage . So when thewet shot activate it went ultra rich 10.0 a/f ratio until the dry shot kcks in and the a/f ratio went to a constant 11.8 a/f ratio . The power didn't drop under 350 hp from 4200 rpm to 6200 rpm . I made peak power at 6100 rpm . It reved realy realy fast and smooth . If i hit the 225 ahot at once around 3500 i should have more then 500 rwtq !!!

why stop at 225 though why not got for 250 or 300 just kidding, how much do you thing the crank will take, i ve heard numbers for turbos but your a completely different ball game with nitrous. any thoughs onto using a progressive controller over a 2 stage?

I was thinking on a progresive controller but if i went with 225 shot wet without direct port i would have some fuel distribution problem with all that fuel into my intake manifold. So thats why i decided to use this setup . Well , the crank is strong . Well if i put 250 shot all at once at 3000 rpm i don't think it will handle it . Using a 2 stage it soften the hit . So does an progresive controller . I think for nitrous a 250 shot is the maximum i would use using a progresive controller or 2 stage . I think 250 shot all at once at around 3000 rpm would be like 600+ lbtq .

What do you mean "Well, the crank is strong"? Just wondering if you put a new one in or have the stock one. I've heard people talk about some scat crank but have never talked to any1 with one.
