Hey guys,

Just wanted to share some updates with our shop car. We went ahead and built our engine to ensure we didn't have any failures.

Engine mod list is as follows.

-Sleeved block
-625 aged studs
-Fire rings
-Forged rods and pistons

We are building the top end as well but wanted to see how far the stock turbos could go. The cylinder head will be CNC'd, oversize valves, our custom cams, and full valvetrain. We're expected to have that done in the next month or two.

We've found stock turbos will get to about 34psi, results are below.


Complete mods list:
-Eventuri intakes
-RK port meth
-RK downpipes
-RK built engine
-Pure stage 3 transmission


Tuning provided by Utku Noa Performance
Stock: 448whp/445wtq
Stage 1: 511whp/523wtq - 93 octane
Stage 2: 566whp/581tq -93 octane
Stage 2.5: 682whp/628wtq -93 octane + meth
Stage 3: 696whp/666wtq -race gas + meth turbos maxed
Testing was all done on same day on an AWD mustang MD-1100SE

In the next few weeks we will be finishing our billet manifold, hybrid turbos, full frame twins, and single turbo upgrade
































Heres a teaser of the twin setup and the single setup.





Thanks
-R
