10 sec 4.8
Been a while since this ET but thought i would share.
Customers juan razo RCSB 4500lb full weight ac daily driver
Engine is a gen 3 4.8 NNBS intake stock 706 heads chinese studs oem headgaskets KHP turbo kit s476 batmowheel bullseye turbo T4 with a 87mm turbine wheel
Has an ls9 oem cam, stock pushrods, and btr double springs
Transmission is a 80e with internal dual feed mod and a 2b circle d converter
Rear is 10 bolt with moser axles detroit tru trac and 4.10 gears
Stock driveshaft, stock front shocks, stock rear shock location, VAS traction bars.
Tires are et street R and wheels are racestars, 28" tire and 17" wheel.
Fuel system is 2 450 lph walbros in tank, 8 an feed, aeromotive fpr, stock truck fuel rails, 210 lb injectors, e85.
No idea on horsepower nor torque, made 800whp/800wtq on 20 psi on a cast standard t4 s475, I am guessing it's close to 1000whp now that the truck is on 26 psi.
Best pass and ET to date is in the slip, 10.04 at 138mph
Going to use a gen 4 aluminum 4.8 next with ls9 cam to see if it can go 9s.
This is on a 2 psi launch, footbrake, and has 24 psi up until i lockup the converter around 100mph which then shoots up to 26 psi. Timing is 12* at peak torque and 14* afterwards.
