GT350 Intake on Ford Performance Website

[MaskedRacerX]

Just got the initial tune from Lund downloaded to the car, gonna put some miles on it, the datalogs look good, so I'm gonna drive it for a day or so and let the tune fully adapt before putting the car back on the dyno....Interestingly enough there is still some faint throttle surging, which Lund assured me is even present in the GT350, something to do with the throttle body calibration...however it's only noticeable in the lower load gears at part throttle (1-2).

I will be using the same dyno I used for my baseline, and will ask them to overlay the 2 dynos so any changes are easily discernible.

Nice. Are you also running LTs or any aftermarket exhaust components? Apologies if you already covered this.

No long tubes (yet) only mods on my car are a resonator replacement x pipe, and replaced the stock mufflers with magnaflows, and the Steeda restrictorless intake.

Only change between dynos will be the GT350 intake manifold, throttle body and revised tune.

Ok I didn't know what your mods were. SO you going from basically a stock motor with a Cold air intake and Cat-back exhaust. Now I am really curios about the power curve. This should be really interesting now your adding a better flowing intake, bigger t.b. and revised tune.

Does the GT350 intake still has the Charge Motion Control Valves in it like the stock intake does.

It does retain the imrcs (cmcvs, whichever), and that was the goal, to test this intake as a pretty much stand alone bolt on, a dyno with long tubes installed will follow in the next few weeks.

Exciting. So how was the new 87mm tb install, does it require a wire harness or pin mod or just straight plug and play.

 

[sandeale]

Straight plug and play, for everything with the exception of some vacuum lines which i will cover in my new thread after the dyno

Lets get to it! :clap2:

Any first driving impressions .. Have you pulled it past 7k or are you waiting for the dyno ?

Any updates on the dyno results of the install?

Sorry for the lack of replies, I've been working a 2 am shift for the last couple of days, no dyno yet, they've been tied up tuning customer cars, I'm going to try again today.

As far as driving impressions go, I've been running my previous set-up for the last 17,000 miles, so I trust what the ol butt dyno says...the car definitely pulls a lot stronger from mid range to my current rev limiter of 7600, there's no loss of steam around 68-7000 like with the stock manifold, It's just a full pull to the limiter. I've actually had to readjust my driving style because I could feel the car just start to peter out up top and would shift accordingly, here recently I've inadvertently found the rev limiter, so now I actually watch the tach to make sure it doesn't become a habit.

I have a feeling the pull would continue higher, but until I beef up some of our more frail bottom end parts (oil pump gears, crankshaft sprocket and probably timing chain guides while I'm in there) I'm going to maintain the 7600 rev limit although might bump it to 7800.

So as soon as I get to the dyno, expect the pull to end at 7600 for now.

I have mine set at 7500 rpm with my mods even if I am shifting bellow 7100 but kissing the limiter on powershift. With a intake I would not put it much higher than 7800 rpm without oil pump gear and crankshaft sprocket. Better safe than sorry. I think 7800 is OK but you know what is best for your car.

Waiting is killing me

Yeah those clowns that own the dyno arent helping my anticipation either, hopefully they're done with whatever they were tuning today and i can get a couple pulls in..

 

[5starr0]

interested in results

 

[sandeale]

Well just called the dyno shop theyre closing at 12 for new years and have cars lined up to pull so i scheduled an actual appointment for first thing monday morning, sorry for the wait, maybe the holidays arent the best time to go all experimental on the car and leave folks blue balled for what seems like forever

Regardless it leaves more time to revise the driveability of the new manifold, still some surging at around 30% throttle below 3500 rpm Lund is pretty positive its some of the driver demand tq management tables, so he's gonna make some adjustments and we'll see how it goes
