Finally got some N20 Dyno's :(
Finally got some N20 Dyno's :( I'm not really happy with the results. I need to go up there and sit on the dyno and tun it. Still just running a basic quick safe Dyno tune (rich). And 25* MAX timing.
Anywho Na #'s in Sig
On the 100 shot (according to nx sheet) 447hp/520tq
So i TRIED the 150 shot. Did not work so well. Last time i ran it one nigt with some 100 octane for a street race it cutout or missed in the high rpm's. So i took the gap from .38 down to .34 On the dyno 495hp/518tq. This was at about 5000rpm from there up it sputtered. I'm guess i need to try a smaller gap still???
Any suggestion's? Anyone using there own "home made" jet chart that works better then NX standard chart? I need to get some more HP/TQ out of this beast!

Re: Finally got some N20 Dyno's :( This was a different Dyno then used for the N/A #'s. And it was about 95* outside yesterday. But i guess i expected more. Am i expecting to much?
Re: Finally got some N20 Dyno's :( It was a group dyno day with a lot of cars. They didnt hook up the wide band. But the scanmaster stayed at around .910. I have a walbro 255lph pump and 30# injectors.
On a side note i was talking to a buddy who ran his after mine. He said he heard them saying the temps were 105+ inside the building. I bet the DA was REALLY HIGH. But the dyno correction sould have corrected for it. But it cant correct for my car missing. Maybe the heat just killed me. We will see after i close the Gap on the plugs and try it again...

Re: Finally got some N20 Dyno's :( Heads, 224 cam, mac headders, x-pipe, ls6 intake, 12 bolt 4.30 gears, nitrous driveshaft, ram clutch,full suspention,etc basically the works. 407 on motor. The car has never been tuned really just got the fuel close with edit and called it good for the time being.
Re: Finally got some N20 Dyno's :( You can see in my sig what I have. Jayson at MTI tuned mine 26 degrres and alittle rich. I wanted to go to 150 jets. Jayson said no. The stock bottom will jot handle that much power. I have fuel pump and injectors. Mine pulls really good all the way till 6000rpms. That is when my pills pull the spray. I shift at 6400rpms. Thats a A4 for ya! We tuned with LS1 edit on the dyno N/A and on spray!

Re: Finally got some N20 Dyno's :( my untuned 390 rwhp NA cam only car takes a 175 shot all day long with no issues.
and we've got another car that is a tuned heads/cam car that has been taking a 250 shot on the stock bottom end for the last year. As long as you've got enough fuel, the stock bottom end will take just about anything you wanna throw at it. (under 7000rpm)
