Ok no answer I'll put it this way. Ive done a 150 dry set up on a 6L before but I'm not sure if a 4.8L can handle that much or shoud do 150 wet to be on the safe side?
Dry can be easy hide but if I go wet I going to have to restrane my self not put in the 200 pills. The videos of all this sould be funny and I'll try to get them up asap but my time is very limited during the week.
Thanks!

i am sure you could hit it with at least a 175wet.

dont spray under 3000rpm and watch your 02's the first couple of times you hit it and put some good gas in there just for some insurance.

i ran out of fuel pump on a 6.0 with 175jets so a 150 is max on a 6.0 but with a 4.8 you might be able to go all the way to a 200shot and not run out of fuel.

Thanks for the reply parish. I'll probably do 175shot and 10 gallons of 100 octane. To bad it will take a while to get videos of this done but it will be alot of fun!

Dont be scared, run the big dry shot.
They're more fun. Mine does great 70mph burnouts, to bad it wont hook though.

The little 4.8 has the same size injectors as the 6.0. The 4.8 wont move as much air as the 6.0 so you do have more room left for a dry shot.

i wasn't talking about injectors, just the fuel pump.

i dont think the stock injectors would properly support a 100dry shot. my injectors were nearly maxed on a stock 6.0 and with a cam were at 110%

I've always had problems with consistency whith dry kits. But its not going to matter much its more about racing it and acting like a fool!!!
