Are 11's possible without a power adder?

If so - how would you do it?

I very seriously doubt that 11's are possible without a power adder. Most guys cant get 11's with an adder. Guess it would be possible to take a Mark into the 11 second range NA with a big mountain motor. Just dont think it would be based on the 4.6. I would love to be proven wrong though.

if you can get a mustang to do it, y not a mark?

id say, race cams, head porting, sulivan intake, 4.30's and all the little goodies that go along with it could get you into at the least very low 12's. especially if you get the upgraded valve train that lets you rev past 8000 without worries, or w/e that job is.

possible yes, streetable no!

depends on what you concider streetable? Daily driver? or streetable? 2 diff things.

All of those cars were Mustangs. 500 lbs or more lighter. It would take serious HP to get a 4000 + lb Mark VIII into the 11's. Just remember, I did not say impossible, just that I seriously doubt it. And the cost factor alone would make Power Adders much more economical. Stroked 5.4, tubed, lightened, 9" rear with steep gears = very possible = very expensive.

no mention of price restrictions.

I do want it streetable and passing emmissions - streetable as a daily driver

Not IMO, they are the same thing. Any car that I don't feel comfortable driving in any conditions (shine, rain, or snow) is not streetable. Also, streetable needs to also be street legal. Now, I can make any car streetable based on your analysis just as long as you can control your foot.

IMO no, not streetable anyways. to do it would require at least 500-600 RWHP, high compression and a steady diet of high octane racing fuel. but if your wallet is fat who knows? I would call the experts at Roush Racing, and get out the plastic.

lol, yeah...im going with no. Its hard to get a true drag car to do 11's and be good as a daily driver and make emmisions. Id immagine itd be harder to do it with another 500-1000lbs.

Says that you'd need 617 Hp to get that porker into the 11's

And thats 11.99

Hmmmm that would be a difficult chore out of a N/A 4.6 Mod motor

Joey, I would say that with the 5.0 Cammer motor (4.6 based), tires, gears, converter, exhaust, tune, and all the other little add on goodies, it could be done. I believe that motor is 400 hp before add-ons. The 03/04 Cobras are running 11's with only appx 450 rwhp and that's without a lot of other mods other than pulley and tune. And those things are boats too! It would be expensive, but it sure would be fun to try!

If you strip the Mark down a little bit you can get closer to the weight of a Mustang. I don't see that being a huge issue.

welp im gonna try to get a mod motor built up for low 12's mabey high 11's N/A by this time next year... mark8 alum block .020 overbore, 302 stroker kit, stage 2 shm cams, high rev valvetrain with double valve springs for 8000 rpm rev limit (hopefully), stage 2 mach1/cobra heads (shm also) and probabily sulavin intake, and all the little goodies i need to upgrade along with that. ill figgure out the exhaust once it gets in the car. (prolly gonna have geno do that) The motor will probabily be finished by christmas 06, and on the street in the spring of 07. We will see then. This is a very ambitious project for me, but i think ittl be a reality within the timeframe i setup for myself. Im gonna need a lot of help with this project, im sure ill get a bunch of help from yall here on LVC. When im done with it, ill try to answer your question about 11's NA on a street car. i think 12s though.

PS: im gonna keep it as sleeper as possible.

when did you win the lottery?

when did you win the lottery?

i didnt, im in college, so i dont have any real financial responcabilities, and im makin $10 an hour, so the moneys not realy gonna be that much of an issue.

oh OK :shifty: heh heh!! but your gonna need 20 per hour for what you got in mind.. Lolol!! be sure and brush up on the spelling while your there...:D

Mr. Wilson, you have the right parts in mind but you need a budget upwards of $10,000 to get everything done right.

I am just curious as to why some of you are aiming for 11's N/A? I am not knocking it in any way, just want to see why your going for it in N/A form?

yeah, i was just pricing everything out today, and it came to about $11.5...so, iv changed my mind on whats going down...im gonna forge the internals (ill see about the stroker kit still, i hope ill still be able to afford it though) get the heads ported, mildly upgrade the valvetrain, and put a kenne bell 1.7 on top. that comes to anywhere from about $7000-$8000 (pre install).

Well that Sux! I was hoping to see a huge N/A Drivetrain for your car. Ah well whatever smokes your tires :D

There is a guy on the T-Bird boards running 12.2's with a NA SOHC 4.6, so I do not see it being an impossibility with the Mark VIII.

Short answer, for me, is this.

Gimmie enough nitro and ill make a TC limo hit 11's (engine might not e worth anything afterwards though)

I dont wanna cheat. I think if nitrous as cheating to a certain extent. To mw, nitro is fine for adding just a little extra - but it takes work and creivity to get there n/a

Ok that cool. That seems like the answer most fella's use when deciding to stay N/A. I gotta admire you guys. For making the big horsepower it gets really really hard to do when staying N/A and stock stroke/displacement. I am one of those people that like to cheat with F/I, which is only due to me wanting well above the horsepower limitations (600rwhp on a 4.6 V8)that a N/A setup could get me. Either way it is all fun. My hats off to you gentlemen.

for the kb you will need (help me out) c head( tumble ports) which you dont have in the mk8 which will cost another 700-1000 bucks and new header to match the exhuast port on the heads. you will also need to do other minor upgrades.. a/f, a tune, install price if someone else is going to do it. you will also need custom tubing for the kb. might as well sell that 4.6 and get a pushrod .........much cheaper.......or look for a 03/04 cobra motor..i know someone that just bought just the motor just 3,500$$$

I do want it streetable and passing emmissions - streetable as a daily driver

as for passing emmisions it would have to be , Old like a '69 where as most emmisions , Or a diesel witch dont have to be smoged and drop a gas power plant.

daily driver ?? I would say your nerves will be shot in less than 3 months , tires always braking loose , 1 drop of rain on the ground and you'll have to pull off the road. Cops driving by your house all the time.

before I would set my sites on it , find someone who has a 11 sec car and have them take you for a ride,

I've been in a few cars that have had no business on the road , V8 vega , 68 Cutless (that took the paint of the street on a launch)
All these guys said they be daily driver, and end up in the drive way. One guy who had to go to the airport to filler up. he spent more on the gas than the engen in a year.

I owned a 72 ford currier with a 302 w/ 4 sp , in no way was it 12 sec car yet
I spent lots of time side ways it got to the point I wouldnt use first gear hell I
blew away a chevy full size truck with a 350 in it staring in 3rd.

just tonite a was passing a corvette (it was raining) and they must have not liked it or thought I was tryn to rase them they jumped on it and almost fishtailed in to my lane. but it was a girl driving it

All he would have to do is swap out to either SOHC 2V PI heads and use the Kenne Bell 1.7 or 2.2 kits for the 99-04 Mustang Gt's or swap to a set of 03-04 Cobra heads and use the KB 2.2 or 2.4 kit for that(making sure that you ordered the IC assembly too).

For the price of getting an 03-04 Cobra motor you can have a fully built bottom end capable of handling way more than even the stock forged bottom end of the 03-04 Cobra's.

Even if he did that engine swap to something else all of that stuff that you said would still need to be done. As for reverting back to the older, and way less mod friendly pushrod motors... Not that they are bad or anything but why take a step in the wrong direction? The 3.9, 4.6 and 5.4 modular V8 stock heads flow extremely well, so why restrict yourself by going back to a pushrod head design with less combustion/flow friendly heads and more operating parts that can break, fly out, or otherwise cause havoc? And lets not even mention the fact of having to swap and tune for managing a totally different engine system as compared to the perfectly capable type of system that is already in his car.

I say get a set of used 03-04 Cobra heads for real cheap, run the kit at 8 psi on the stock bottom end till your used to the power and ready to build the bottom end and then swap the heads and everything to a built shortblock and turn up the wick to 15-20 psi(if you get the KB 2.2 or 2.4).

The even cheaper route, but still able to make tons of power, is swapping down to 2V PI heads from a 99-04 Mustang GT and using the KB kit for them.

If you want to stay n/a, and you are looking at spending that kind of money, I would seriously consider buying the 5.0 Cammer motor. It comes with the best heads and cams you can get from Ford and makes a ton of hp. You can also order it complete with an ECM tuned just for it.

DO NOT buy a used set of 03/04 Cobra heads!! They have been updated several times since introduction due to the "tick". If you want Cobra heads, buy only those that were released in January of 05. Those seem to be the cure and also come with more spark plug threads to prevent blowing the plug out. They are something like $1500 for a pair...complete!

The 5.0 Cammer motor is a great motor and all but it is overpriced. You can build a 5.0 or even a 5.3 stroker/big bore with some nice Cobra R heads and make some serious power for allot less than the cammer crate motor. If you just want to drop in allot of power and don't mind spending more money then by all means get the cammer.

The reccomendation for buying used heads was based upon keeping the budget somewhat low. Buying a set of used Cobra heads and then reworking them to take out the tick is not too bad an option and will save money.
