Back from the dyno.


Well it made pretty good power but we had to back out the timing because I was running out of fuel. He said once I find the problem he could probably get 620-630 out of it.

The only thing that bothers me is the drivabilty is still crappy maybe even a little worse. Anything between 2-3k and about a 1/4-1/2 of a pedal it farts and misses. If I floor it, or get past 3k or under 2k it's fine. My fuel system should be good to about 650 but for some reason it not holding up.

He thinks it might be an internal leak in the tank. , I'll save some money find out what is causing my miss and return. I also noticed on the way up that my speedometer fluctuates a little ever so often, who knows? I'm glad it's making decent power. Even though I had to leave a little on the table. But the drive ability is really bumming me out. He data logged everything possible did lots of part throttle runs but nothing shows up? But as soon as I get in real world conditions it starts it's crap.

Well here's the numbers. 598.5HP and 531.4 TQ. Not bad for a little Vortech V1 S-trim. So I guess the patriot heads make power after all. He asked me if I wanted to put 1 more degree of timing in it and try for 600 but I didn't want to push my luck with the questionable fuel system. I'll get it next time.

I have to 2 in 2 months. It's getting old. What did they do to fix yours? Who does your tunning?

It didn't show up rich on the dyno at part throttle.

JMS in Mississippi did it. I can call him to see what he did but I remember myslow was saying that the "tip in" (I think it's called) needs to be messed with to get the drivability right. It may be better for you to talk to them and explain your situation.
The number for JMS is 601-766-9242 if you want to talk to them. Ask for Monty, if you want to refer to my car, tell him Mike Seoane (see-ohh-knee) sent you. If by some chance he doesn't remember my name just tell him that I was the one from Louisiana that made several trip there because I was having issues with my NX kit.

Besides a Forged bottom end, Patriot heads and a V1, what are your cams, pulley with lbs that's making those sweet numbers? Do you have an 8 rib set up?
