sweet video, first pass was an eye opener. That's a cool pickup, sounds rad

[LowTensLX]

very nice!!!  I love the rear mount turbo config...looks bad azz and frees up all that space in the engine bay...Excellent job!!!

[chameleon]

That is one cool setup man! Trucks don't usually get my attention but that is nice.

[turbo hemi]

Cool truck 

[flybynight]

Now this would be an awesome truck to tow my mustang with, but that would be strange having my tow truck be faster than the car its towing.LOL, nice truck.

It would be a cool race for sure .          

But man , look at that MPH !          If that truck left on some boost and got the 60' times down , it wouldnt even be close .       



svojohn ,      have you had it on the Dyno ?   Calculators are saying almost 1100hp . 

[AlexL]

And they say rear mounts don't work... 

[Losls2]

And they say rear mounts don't work... 

That's mid mount . Badass for sure. Big props for thinking out of the box!

[huffer]

all the thinking and props are in the box


How much boost are you leaving on?

[bgjohnson]

That's a pretty sick ass setup. Very quick truck!

svojohn ,      have you had it on the Dyno ?   Calculators are saying almost 1100hp . 

I hate using dyno's because I have terrible luck with them.  At first we did put the truck on the dyno to help dial in the tune but unfortunately for us the engine spun a rod bearing and wiped out the mains.  The truck never went WOT on the dyno.  If I remember correctly the truck put down 426 hp and 750 tq during a part throttle pull.  Than the rod bearing let go.  The video link above is with new rods and a crankshaft.   

How much boost are you leaving on?

Currently the truck is setup with the least amount of boost we can get and with the most lag possible.  We'll bring the boost in sooner and turn it up once I get the tune dialed in better.  In the video link above, he's launching off the foot brake around 2500 RPM and 0 boost.  According to the data log we're seeing 13 psi in 1st gear, 18 psi in 2nd gear and 22 psi in 3rd gear.

Great setup man 

[tt97cobra]

Wow!   

[BlownShovel]

I smell a grudge match with blown385.

I thought the same thing.. and wondered if all Fla truck are that fast?  Nothing but slow muddy trucks up here 

[went12s]

Wow that first run was a little hairy...lol
man the thing flies on the top end. 

[Torqued]

The video link above is with new rods and a crankshaft.   

I read this thread a while back. Impressive.    Could you share some details on the engine build?  (Pistons, heads, compression, exhaust manifolds/headers, etc.) 

[v8huntr]

sick

[svojohn]

Here's another video of the truck from earlier today at another test-n-tune day.  Had trouble with the BS3 data logging so no tuning changes were made.
