Hi Guys,

Since it looks like it is going to be a while before we can adjust the fan temps with a predator, does anyone know how to jump the fan relays in the 392 to help with heat soak. I am seeing temps of 215 degrees even with my 180 degree thermostat installed. The fuse box appears to be much different than the 6.1 hemi and the relays are in different locations in the fuse box. Any help would be greatly appreciated.

Thanks,

Gary

Can you post a pic of your TIPM? I know they changed it once from '09+ but I don't know what the new one looks like.

I am guessing that by TIPM you want a picture of the fuse box in the engine bay. Here is the picture, any help would be greatly appreciated.

That worked perfect, I ended up jumping the high speed fan. I was able to get me temp down in the 180 range and made an 11.9 pass last night. You rock!

Congrats on the 11s!

Planning on moving up to 100 shot anytime soon?
Since Diablo hasn't cracked the code for the 392 yet and it looks like it is going to be a while before they do I am thinking that I might be ok running race fuel with a 100 shot on the stock tune without pulling timing. What do you think?

Yes, that was with what came out to be a 70 shot on the dyno with five gallons of C12 mixed with a 1/4 tank of premium and 400ft. DA.

In theory increasing the shot size shouldn't affect KR since you're adding additional fuel with the increased additional nitrous.

Though you're right, without the cracked PCM you can't even monitor the KR on the car.

Are you using a window switch in your nitrous setup? If you start spraying slightly later in the RPM range there's a smaller chance of nitrous burp and since during a drag race you're mostly staying in the 4000-6000 range throughout shifts a higher shot will give you more oomph on the upper end.

Ideally you'd want a progressive shot that increases with time/rpm but that's getting expensive :)
