it should perform similarly to how the VTX setup did? less (LOTS LESS) in the midrange where the pump struggles, but it's fine higher in the revs - the VTX had a small pressure drop in the midrange, but nowhere near as bad as the stock frames. "

single 4" SS exhaust with one vibrant flow thru resonator/muffler. and of course ... open dump from the wastegate.

screamer pipe?

LOUD NOISES. "

it's pretty well known that jet's read higher than mustang/dynamics (any load dyno) WHEN they're set up properly? compared to an inertial dyno "

mmm fair enough

not sure there's even one within 200km of me actually haha

hopefully i can find one when the time comes

OR i'll make enough on a dynamics that it doesn't matter

ED: yeah there's only 2 registered dyno jet's in australia... New south wales and Western Australia... i'm in QUeensland... 577miles away~... never going to happen unless there's an unregistered one here haha "

ahhh so yet another 'packaging' constraint

we pretty much ONLY have dynodynamics here... but they consistently read a lot lower than the numbers you guys get on your dynojets (my N52 reads 15-20whp lower at least)- i'll have to try and source a dynojet in brisbane here one day lol "

*adds to job list*

and they do springs/retainers only for tons of cars/applications already, so this should be a pretty good bet.

just thought i'd try the easy options first if anyone knew
ED: it'd be a better idea to get fresh examples rather than worn though wouldn't it? *checks new parts* "

he also mentioned it was still dropping pressure for 500rpm in the midrange, where stock turbos make even MORE power than their stage 3

so it makes sense for the stock/stage 2's to seriously die in the ass "

that's what i'm wanting to run - E85 no meth :/ "

I know there have been a few anomalies out there (wedge, ect) who have been able to run 100%e85 with no issues but I believe most (if not all of them) are funneling a ton of meth in there to keep things happy. Stay tuned as Undercover tries to get this fuel situation in order.

ohhhh no, so the vargas upgrade doesn't help enough in the midrange?
... so it's only really fixed it in the upper RPM's? (so far as it's appeared at least)

.... a really difficult upgrade i take it? moreso than what's already done?

@VargasTurboTech ?

I noticed in those road runs IAT was lower so much more actual power is being generated which puts that much more stress on the fueling.
