that is ridic.


I couldn't put an on3 kit on SBF in a foxbody that fast.

Excellent. I have a feeling it gets a tad louder at WOT.

update on setup: I drove it down to the scales curious as to what it weighs now, with a full tank of fuel and no driver it came in at 5860 {9.5sf 14bolt, 3/4ton leafs, 35x12x20s, aluminum motor, turbo kit and full 4" exhaust}



ive logged about 60 miles so far on this truck in last 4 hours, heres what Ive found out. 10lb spring equals 7 psi, with 11* timing the Pcm is calculating right around 540/540 to wheels after deducting drivetrain loss... To reference my old combo made 540/545 on 12 psi and 18* using a 10pgh meth nozzle.

as for spool i can say depending on load ive heard the turbo make its unique sound by 1600-1700 rpms, Ive saw full spool by 3400 rpms. Boost is rock steady on this combo and is night and day different vs the old combo. Driving off boost is so much nicer

did some more calculations and seems as my compression is little higher then 10.8 and more around 11.1, with how its acting now I may just leave it at this power level and enjoy it. I was happy before and now making similar power with even less boost and less timing on 93 alone....The old combo when I was daily driving it only had 12* timing in it on 12 psi

arent CAT scales only accurate to 50lbs on anything under 10,000lbs?

i always wondered this

probably - things tend to loose resolution under 10% if they are rated to 100,000lbs!!

Picked up a set of long bars from Alligator performance, not a bad product.. I chose to weld the front mounts to the frame. On my style frame you dont have access to be able to bolt them up. With this setup the only true welding required is the rear tabs to the U bolt saddles

ive logged little over 300 miles in 2 days of driving this truck. During that time with mixed driving the truck has averaged 15mpg

this may not seem like alot to some but ever since i lifted this truck and put these 110lb each whee/tire combo it has gotten shitty mpg. Im seeing better mpg then I did with the 5.3 and procharger

this is also with 4.88 gears

[somethingclever]

That is about 3 mpg better than I would expect.

[PaxtonShelby]

Amazing mpg - big heavy truck with all that power.

God damn dude, you must never sleep.

Towed with this truck yesterday, pulled my enclosed with cocaine in it. Hands down out performed the blower setup. Truck held gears better, i never had to go over 3500 rpms..I was in full control of boost and kept it around 4 -5 psi by use of my foot. With this amount of load turbo lit was full tilt by 2100rpms..Power off boost made huge difference. Truck wasnt working hard what so ever.
Little over 14,000lbs combined weight... Round trip little over 100 miles

Hope the Feds don't read that last post or they'll be knocking at your door.

14,000 for truck and trailer isnt that bad

[Dan B.]

That's awesome. Good work!! Seriously jealous of your skills.

[PaxtonShelby]

14,000 for truck and trailer isnt that bad

Just meant that's a lot of cocaine...bad joke....sorry

Little update on this project...the 6.2 had assembly issues so was issued a full refund. So i decided to go ahead and have a 402 built
Callies compstar rods
Callies compstar crank
Wiseco pistons
Iron block
Coated bearings

Same cam as before 224/224 578/578 114

Block was professionallly painted using ppg basecoat clearcoat

[George C]

Picked up a new set of trickflow as cast 220s for ls2 bore
Also chose to use a ATi super dampener, cloyes double roller timing chain and Slp oil pump


This combo will be around 9.9cr

With the short amount i drove it over winter things got ugly from weather...so for this time around i went ahead and had things powdetcoated and jet hot

[George C]

With having a twin scroll housing on a open manifold i went ahead ported and knife edge the housing prior to coating
