...what's the max with 370s and a Walbro 255? I successfully ran 125-shot on Sunday... I'm thinking of pushing it a little more...

<--200shot:eek:

Thats where you call it quits on 370cc inj bud. I have run 160shot of NOS but it will not last. It will yake between 1 and 5 trys before you snap a rod.

so what's the max on these injectors for the JWT dry system?

A 55 jet which is 125hp. When using this jet please raise fuel presure to about 44-46 at idle. If you have C16 gas run 40 PSI at the track.

Thanks, A. I actually have successfully run the .055" jet with 100 octane fuel. It ran very very strong.

If you use a progressive controller, using that amount of nitrous as long as your mixture isn't too lean would be fine and you'll get better traction and performance from your nitrous system also. Since your using a dry kit, I would look at Crane's Digital Nitrous Controller. Designed to work with dry kits, you can reduce power between 50% and 75% at launch to give you better 60ft times and by ramping up the amount of nitrous injected you get turbocharger like performance also. Which would allow you to increase the nitrous flowed even more.

Seriously I would check it out, it's under $300 at most places that sell Crane stuff online. Has a built-in automatic purge feature also. It's RPM based and since you have a distrubtor providing a clean signal shouldn't be a problem.
