Speed hole in the block?

If that was the case, I would have posted exactly that. The unexpected twist is a good thing! :P

Speed hole in the block?

LOL that was my first thought sadly.

Dun dun dun indeed! LOL

First I'll start with the twist: I'm out of fuel pump! This isn't supposed to happen on a pump gas stock turbo X, I must really be flowing some air ;) My tuner says the car definitely has more in it so once the new pump is installed the tune will be further tweaked.

Prior tune = 342whp/360wtq
Baseline = 345whp/359wtq
+ PPI extreme ported exhaust manifold
+ Mil.Spec ported IM
+ Mil.Spec ported TB
+ MAP phenolic IM gasket
New tune = 360whp/378wtq

That's +18whp/+18wtq from my previous tune plus gains, including quicker spool, throughout the entire powerband! Damn impressive for stock turbo/pump gas on a Mustang Dyno especially considering the car has more in it yet. For comparison sake, my IX (w/cams, etc.) put down 360whp/369wtq on this dyno.

I am beyond excited to get a new fuel pump in the car and get back for more tuning!

Impressive Kracka,

That is some awesome power gains, what are the predictions with a new pump? How much is left on the table?

Tough to say, but even if they're minimal and only add a bit extra margin for safety I'll be very happy. If I hit 380wtq I'll be thrilled, but that may or may not happen since it's not down low where the car is out of fuel. I'd say probably at least a few more whp but we'll shall see...today exceeded my expectations, we'll see what happens next time :)

Nice! You just made a FQ-360 on stock turbo. Could never understand why Ralliart UK needed to swap turbos on any of the FQ series ( VIII, IX, X) to get those numbers you just achieved.

Kick ass man! Lets see some graphs! maybe an overlay with gheyrod IX before she blew?
