Switched from GT40 intake to Performer RPM intake....

I can't stand the non-lockup converter my red car has. I wish I hadn't let Dirty Dog convince me otherwise. I mean I do generally cruise at 75-80 on the highway but that's about 2700-2800 rpm anyway. It's a 3000 rpm converter so it's not quite stalled. The thing absolutely drinks gas :hick:

Yes, I know, the 2-3 shift has a reverse of direction in addition to a big ratio change. As they explained to me. Yaaaaknow what I say? What Bill O'Reilly once said: "F*** IT! WE'LL DO IT LIVE!!!!" :rollin: Most of the time I let off the gas during upshifts anyway. I developed it years ago as an overkill habit. So there LOL.

When I got home last night and looked at the pictures, it does look like my Trick Flow setup I had as far as the proximity of the intake to the distributor. Just cut a section from the back of the boot (I have extras if you need one, just shoot me your address and I'll send one), and it'll fit. I always thought that helped to clean up the look of the engine.

that is a jaw dropping engine bay!!!! very nice work looks factory. clean not butchered


Thanks. It shouldn't look butchered when you install aftermarket parts. If it does you're doing it wrong ;).

Really? At 75mph the car still gets ~23mpg even though it's a couple hundred RPM below stall speed. Driving my Mark VII with the stock converter that locks up in 3rd there is a noticeable drop off in acceleration vs. the non-lockup converter. I actually prefer the non-lockup converter as far as drive feel goes. I can also care less how much 93 octane Shell my Thunderbird drinks. I've got a Focus to drive every day and get good mileage with.

Thanks for the idea. I'll try cutting a bit from the back of the boot until it just fits. I've got a couple of extras sitting around.

I do LOVE being able to flash the thing at any time and get a nudge forward...I've done little highway with it but I know the digital readout doesn't stay above 20 much under any cirspoogestances. I'll have to test it more. And there are other things not guaranteed too...O2 sensors, the fact that I have a 160 degree stat, EGR vac line plugged off, etc.

The thing is I'm pondering taking it to Mustang week in SC with my friends since I grenaded the other cat. The one guy....*might*...take his newly acquired Terminator. With a 3k RPM'd 4R70W, Whipple 2.9, etc...thing gets 95 miles to a tank right now. Mustang Magic in LI dyno'd it at 576 RWHP. They declared it to be in good health. So it could always be worse!! I'm just so used to fuel, comparatively, lasting days and days and days in the black car.

That would be less then 6mpg, that's absolutely ridiculous. For my daily commute, i would have to fill up twice to pick my kids up from daycare.

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

I've got the EGR removed to no ill effect on gas mileage. Just don't break the red Cougar like the black one on this trip ;).

I was going to say 576rwhp might have something to do with that but a GT500 with around the same amount of power gets better mileage.

I drove the Thunderbird around today. Highway passing power has been much improved by the swap. In 90* air Temps with the A/C set on 70* blipping the throttle to the floor at 65mph causes the car to pretty much instantly gain 10-15 mph. Top end pull has been improved noticeably.

That's good that it's worked out, sounds you found a good combo despite some nay-sayers :)

Update on that Terminator....that was with a screwed up tune with a bunch of monitors shut off. That part of the story I forgot about. But it WAS drinking it like that. So we'll see what it does now.
I can only assume the black car's heart failure was due to me just slapping the adjustable roller rockers back in during the end of winter 2014, and not adjusting them. What else would cause a broken spring...? The red car's engine has been together as it sits since spring 2012. Bottom end has never been taken apart, and the entire top end is still all factory Ford parts. All H.O. items (intake ported of course) except for the heads. So "I do not antite any issues with this event". Ha.

Well the red Cougar should be fine then :).

So you just slapped the rockers back on the black Cougar without adjusting each one individually? That will definitely cause them to fall off the stud and/or break a spring :hick:.

I don't know all of the numbers off hand but I keep wondering if the tolerances are close enough that it might have in fact been the cause. Good to hear! Truly! LOL. That is exactly what I did. Slapped 'em on. Maybe because the hex adjusters weren't prominently visible...it just never entered my head.

Thanks to Vinnie for the suggestion of tpuppies a little off the back of the distributor boot to make it fit. I removed about 1/4" form the bottom rear of the boot and it fits again :). I also touched up all the A/C lines I scratched when swapping the intake on.

Look fairly snug on the air tube and strut brace. No contact when the engine is revved?

, looks sharp.


Next step...forced induction? :D

With the departure of 100% stock looking parts, your wallets the limit now ;). I always feel terrible about my engine bay after seeing yours, it looks good.

Actually the tube clears the strut tower brace fine. It's closer now as the Performer RPM throttle body mount is .5" higher and .3" forward from a stock/GT40 intake. When revved the tube doesn't hit the brace. However when I'm driving and hit a bump the air tube clanks off the strut tower brace. You can hear it in the car and it sounds like the car has worn shocks or bad bushings :mullet:. I "fixed" the issue with a short length of heater hose wrapped around the strut tower where the air tube hit it. Hence the rubber you see on the brace by the air tube.

Blower isn't going to happen on this engine. It has hyper pistons which aren't really friendly with boost. My next plan down the road is probably giving FTI a call for a custom cam/spring package to really wake the engine up and tie everything together.

Awesome. Glad it worked. I'm with you, the engine looks better with the boot. Once the flooding stops here, Ill be back to cleaning and detailing.
