IRONFIST

Alright, so I ordered some new mods, and Im curious to see how much I'll pick up.

Old combo 387hp/378tq
99 ws6 t56
Stock short block
243 heads, stock gm gaskets/ comp springs
Stock Maf
Stock lid
Eps .598/601 226/234 113 cam
Hooker 1,3/4" LT's
TSP Y pipe

New mods:
Ditching the LS6 for a fast 78 mm
Porting the stock TB or doing the Fast 85 mod (ideas/thoughts?)
85mm truck Maf
K&N filter
MTI lid
E-cut out


Guesses? Thoughts?

Gonna guess you pick up around 25rwhp total. Really depending on how your car responds to the cutout. Some cars pick up a lot some don't gain much of anything.

What exhaust do you have? What merge and muffler?

Everything behind the TSP Y pipe is stock WS6.

So 25whp from a fast, lid, and Maf is the only guess?
that should put me at around 410.
Which is just fine by me...

any updates from the new mods yet?

Still waiting on the intake manifold, Christmas shipping delays. According to UPS I should get it this week.
I will update after it's installed, as long as weather permits me to make it to the dyno shop.
