Harris speed works 78mm plate kit. 200 shot? Does anyone run a 200 wet shot though their 78mm hsw plate setup? Im looking to step up from the 150 to a 200 but im not sure what jets people run for the 200??

Here is an older post by JL ws-6. But be advised that there are different jetting sizes according to what fuel pressure your running and also your feed line -4An or -6AN. Those plates will only flow about 200HP unless you upgrad your feed line to the -6AN from what I've heard. Thats just the info I was given about running my plate. But here ya go. Hope it helps.
With the 175 jetting, I'd run the 77 nitrous jet, but the fuel jet probably needs to be a 44 to start. With the 200 jetting (MAX I would use, and you need to check the plugs carefully to make sure it's distributing in the intake correctly) I would use the 82 nitrous jet, but would probably start of with a 47 fuel jet.
Definately raise the engagement rpm of the spray a few hundred rpm for each increment over 150 you go with too, to help prevent a backfire.

I would get with harris on this, cause I don't think that sounds right. Open a ticket on their site and wait for a reply. It takes a day or so sometimes, but they will get back. I know the response is slow, but it is what it is.

I have the hsw big fuel/nitrous solenoids, 42lb injectors, and the racetronix fuel pump/hot wire setup. My fuel line coming off my stock rail going to the solenoid is very short, but it's the average size nitrous gauge line (whatever that is?)
I run BR7ef @ .032

Also, I can't say for certain but I thought I remember people complaining back in the day that HSW plates don't flow more than a 150. I could be wrong, but that's just what I remember from the past. The solenoids and everything else should flow plenty, but the actually plates themselves were the limiting factor. I would do a search for some more info. If anything, to get you started base it on your jetting for the 150. The nitrous jet will need to be around the 75 range and then jet the fuel accordingly and make changes utnil the afr is perfect.

they probably went up in price because the ls1tech sponsor fee is like $900 bucks a month, i felt bad when i wanted to be a sponsor and they told me the monthly cost, i was like holy ****, not nearly enough traffic to justify that.
