Proposed question.
How could (and is it possible) we get higher lift out of our cams without changing the camshafts and could this work on the 4.0?



Just want to make sure I am clear when talking about getting higher lift (I am sure you know) see below.

To manipulate the intake valve to open just sligthly more than stock to allow more fuel/air in.





Higer lift is there any way to edit this?

Hey guys I am looking (trying to think) of any thing poss. to pick up what I can on theses engines per going S/C. Ok I know guys that have increased their lift on stock cams (without changing the cam) and also did it on after market cams for even more lift with good results.

I do not know if this can or will work on the 4.0 but hey worth questioning and looking into. I proposed the question to see if there are any OP/ Ford techs (lurking) could weigh in or poss. makes them think.

I need an exploded view to look at the 4.0 valve train because I am not familiar with it.

Anyone one know what I am talking about or want to just take a guess?

I'd be willing to bet that the ones you're discussing where the lift was changed without a cam swap were probably in a pushrod engine where you could put in different rockers, rather than an overhead cam setup.

A cam regrind could be what you are looking for, but honestly I wouldn't know if doing one can actually increase your lift, as you are removing material from the lobes, and end up with smaller lobes.
Characteristics can be changed to different specs however, by changing the contour at the bottom of the lobe (overall changing to a different cam lobe design).
For lift I don't know what would be done.

P_kiley & Manehawke thanks for your input/opinions.

Anyone else want to add input/opinions TIA

The factory service manual has just about any details about the mustang 4.0L and all of the other variants (exploder, ranger, sport trac, etc.) that could want. Here is the page about the valvetrain.

Ok P-kiley you were spot on (switching rockers diff years same motor Chevy 1.2 rocker vs. 1.6 = more lift) but I wanted to leave this on till I found a definitive answer I won’t always take no as 100% answer as I will always keep my ear open. I would have to say in this case the person I talked too the answer looks and is no. The guy I talked to is Paul from Paul’s High Performance (Scrming ) http://www.paulshp.com/ I talked to him extensively on the V6 including mods and S/C and according to him because the 4.0 uses the 1.8 rocker there’s nothing we can use or do to increase the lift. You know after I got off the phone with him thinking of the way he said it sure gave me the impression this might have been poss. on older versions.

His next project Jan 06 is a Vortech S/C 4.0 I will be following this guy closely

This guy also has years of experience with Mustangs (I think it was 15yrs)has been in 5.0 and I think Jan 06 Hot Rodding and looks to be my go to man in the future even if I have drive out and get a hotel for a couple days if I decide on his S/C tune, dyno and more.

If you go to his site take note of the 05 4.0 206@237TQ 4:10’s, slicks, pulley, along with usural suspect mods ran 13.93@95.95 N/A I had to question him on this to make sure what I was reading and he said that is the time at 206@237. Hmm..

Good find TJ! Actually I been keeping up on him as well, I posted a thread on TMC I think before you joined about his V6 car hitting those numbers NA, but take a look at the mod list on that car, very extensive. But definitely a good goal and gives us good insight into what our cars can do.

Please keep us posted on your plans and dealings with Paul.

TJ06

Thanks Rygn

But Rygn 206Hp@237TQ ?? =13.93?? N/A

rygenstormlocke

Oh yea, don't get me wrong man, that is awesome. I'm just saying take a look at what they did to the car, and also keep in mind it's running slicks. I'm excited about this car no doubt, just want to go over all the mods.

TJ06

Rygn you're not getting what I meant.

206Hp@237TQ =13.93??? I see maybe 14.50's??206@237TQ, What am I missing?

rygenstormlocke

I have to dig up the mag I read it in about pauls car, but I was suprised too. But slicks does make a big difference and I know the car is on slicks and 8.8 rear end. Might just be hooking really really well. Let me see if I can find it.

Zodiac

14.5s is more in line with the numbers, and I really wonder how much slicks would affect the time. I could see it shaving off a few 1/10s of a second, but nearly 6? He must be launching from like 5-6K or something and hooking immediatly. Id like to see the slip, personally. 60ft times would be a great indicator.

rygenstormlocke

Ok guys, I pulled out my copy of this month's 5.0 magazine and re-read it, and yes, it did say 13.9. I started a thread on this a while ago, and I transcribed the mods they used. Have a look:

http://forums.bradbarnett.net/index.php?showtopic=39569

It's published in 5.0 magazine, 13.9 is a bold statement, but he claims he can hit it, and that was on a 100 degree day.

scrming

I talked with Lidio about Paul... Lidio said Paul is one of the very best manual drivers around... and that he was probably launching, like you said way up in the 5,000 range... So having a manual tranny, slicks and the skill (and guts) to launch your car at 5000+ RPMs will get you in the 13's... LOL! He also got in the 12's with a little 75HP shot from the Zex kit!

TJ06

I found the link to PHP while at Scrming’s site I click on the link and whoa nice, so I start reading and I look at the 13.93 time NA then the 206HP@237TQ. I swear I must have looked at it 3 times to make sure I was reading it right. The first thing I said to myself they must of put an older dyno specs up it can’t be. Then I start thinking what am I missing here?

Well it must come down to what you guys posted, I will put it in a creative way.

Talk about hook & go!
Gives new meaning to the phrase, make the most out of what you(206@237) have!
Good wheelman line do not take it for granted!

Well if he can get that car in the high 13’s on that HP & TQ he will be in the 12’s with his S/C Vortech project.
