For comparison sake, my GTO (4200lb race weight) goes 107-108 in the eighth which equates to low 10.4 at 134-136 mph. You're making some impressive power on that 4.8 for sure. I was making somewhere around 650-700hp at the wheels when I ran those times.

 

dam thats impressive im hitting the dyno this sat just uped the boost a lil lets see what it does

 

congrats bro!! bish is moving

 

With a 108 in the 1/8th and you said the truck is full weight, I'm looking forward to the numbers. Should be very impressive. What springs and timing chain you running?

 

Just some pac springs and stock timing chain

 

its going on the dyno later today, but I wont be there to tweak the tune. Passes will be made on boost only around 18psi with 2 degrees retarded because thats the way it is right now for nitrous. No nitrous passes today, I'll be happy with 620 on boost only.

 

got some upgrades

stall converter
caltracks
stand alone fuel system for nitrous
29.5 slicks on 15" bogarts
still on the 4.8

gonna run it this week les see what this lil 4.8 can do

 

Truck looks very nice on bogarts. Let's see what it can do with the upgrades y'all did.

 

Thats damn impressive for a 4.8. I was always preached the rule of "there is no replacement for displacement..." starting to doubt that LOL

Very nice run

 

there is a "replacement for displacement" its called boost lol


thnx bro
