Is it possible to run 10s n/a with a 3V and...
 

And still be able to drive out to the track on DOT's with full exhaust? What will it take?

My 98 Camaro of course has a 65 cubic inch advantage as we all know, but it does run well into the 10s n/a at 2900#. I could drive it out right now and run a 10. And this with the factory mass air, plenum, heads, block and rear gearing. Not a lot of cam either with my 224/224 on a 112 LSA.

Both cars have a 3500# weight listed on the title.

I'm afraid we have our work ahead of us with the 3V.

Of course its POSSIBLE, Larry. It is NOT a question of possible, but rather, AFFORDABLE :)

N/A??? Whew...that's going to be difficult. I don't think anyone's done that yet.
You could be the first Larry!

You're going to need a shit ton of hook and weight reduction mods. As we all know, the
4.6L's strong suit is not making naturally aspirated power. You're definitely going to
need more cubes than 281". Cams, full bolt ons, a tall gear, bigger cubes, slicks,
skinnies, weight reduction, suspension mods...

Will that auto tranny hold? Not sure. You know you'll need a big stall in it
though if you want it to get out of the hole right.

I would think you'd need 450rwhp at the minimum.

I think anything is possible but I'm saying with the factory block at 2900# just like my Camaro. Forget the factory mass air, plenum, heads, anything goes there.

I think it's only going to take about 400 rwhp. That's about all my Camaro makes based on all the threads I've read with engines with my cam. Although it has not been dynoed with this cam. Can you get 400 n/a out of a 281? If you can then 10s should be easy!

I'll just be happy with 11's :lol: I was going to go the blower route on mine, but have decided to go N/A, since
1. Its more fun, IMO
2. everyone and their grandma does FI on mustangs.

I'm going to try and do it with a 5 speed. I've already done a TKO600 conversion and beefed up the entire drivetrain. Suspension is all done also. Still at stock weight, but will shed about 2 hundred pounds, hopefully. (including drag wheels)

we're going to start the motor mods here soon. I think with all the bolt-ons, good head and agressive cam it will get around 400rwhp on stock CID. that should get in the high 11's without a problem in decent weather.
to get 10's its going to have to be absolutely GUTTED or increase the displacement. I'd like to keep the stock block, it looks like you can go up to a 322 with it. I do not want to gut the car, so I hope with the increased CID and a little more weight reduction it will brush 10's in about 0DA. Maybe on MT radials, but I would prefer just to do it on slicks.

Short answer: No

Long Answer: No chance

You absolutely can get 400rwhp N/A out of a 3V, but it definitely won't
be a 281" motor. You'll need more cubes. Let me ask my friend over
at Livernois about this. I know they've done heads and cams on their
F1 blown 'stang GT. Maybe they dyno'd it prior to the blower...not sure.
I'll see what he would recommend for reaching your goal.

You're a stud if you can get run a 10 with 400rwhp. Putting
all the power to the ground is no easy task.

I'm a stud! I do run 10s n/a with my Camaro with an estimated slightly less than 400 rwhp. I still have factory valves but ported by me. It's all in the 60'. I run consistent 1.4s with 3.23 gearing.

400rwhp with an automatic and big stall might do it. 400rwhp in an M5 won't stand a chance. huge difference between the two.

I think its possible, but that would have to be one gutted Mustang. These tiny cubes also don't have the nice big torque band that the LS1 has, its hard to compare them. A 400 rwhp LS1 will most likely have much more area under the curve than a 400 rwhp mod motor.

It's possible. But your race weight will HAVE to be under 3k. With good air and around 370-380rwhp, 10's N/A is possible. But H/C/I is mandatory. -Mark

I've never heard of a 281" mod motor making 400rwhp N/A.
I could definitely be wrong. I'll get a strong answer tonight

according to blowbyyou's web site their agressive h/c motors make about 385rwhp in an M5. I bet with the right setup after some more reasearch is done into what cams work well with a 3V it could make 400.

Alright...so I asked a very good source and he thought that it's certainly
possible to make 400hp to the wheels through a manual tranny, but it would be
difficult. Through an auto, he thinks it's flat out not going to happen. I tend to
agree.

Granted the FS motors are 4v and are over 400rwhp or right at it but a 3v can get to 400 w/ out the limitations of FS rules. Big cams, lots of timing and alot of compression. Not really street friendly but 400rwhp is 400rwhp. Combined that with a super light weight chassis and I think you can squeeze out a 10.9X pass around 122ish. -Mark

Work on the rest of the setup for now. I bet within a year or so someone will be stepping up with a more HP for the 3v's. Especially once they get some more aggressive cams figured out.

I'm guessing an aftermarket intake would push it over the edge. of course this is without knowing anything about what the stock intake flows :lol: :eyes: I would like 400rwhp on pump gas.

Would we will be able to get enough compression from milling to get 400 hp. Remember I'm talking about the factory block, factory pistons just as my Camaro.

I know you can mill the heads to get 11:1 easily and top that with some dome pistons and I'm sure you get 12:1-12.5. Not really super high compression but add that to the timing, big cams, and maybe remove the power steering and get an electric water pump and 400 is achieveable w/ only 281 cubes, well 284 ci (.020 overbore for new pistons). But on pump gas(93) I don't think that's gonna happen. But Sunoco near my house has 100 so to me that's pump gas. :) It came from the pump. lol. But I'm sure you'll need 110+ for the race tune. It's alot of work to get 400rwhp. Just not as easy as a LS1 H/C/I combo. You damn LS1 guys, can I borrow 65 cubes? :jest: -Mark

EDIT: just re-read your post. On a stock shortblock, I don't know if milling the heads that much would get 12-12.5:1 and keeping the stock pistons. Still learning the 3v stuff.

what is the stock compression on a 3V anyway?

9.8:1 -Mark

I think you can Larry, just going to take a 5000 stall and some big gears. And remove 400-500 lbs. :)

Ken Bjonnes went 10's 2VNA with under 400 rwhp out of a 281. As most everyone has said, it can be done, it's just can you afford it?

Are you going to get enough compression ratio with the factory block to run a cam big enough to peak around 5500? For a 5000 stall you want a cam that has a peak torque around 5500 rpm.

Factory block? Remember I said factory block. If so then it looks like if a 2V can do it, it will be a piece of cake for a 3V.

If you mean stock Ford reciprocating assembly-then no way. Ken ran 10.8's with a 2V, but it was a totally built engine in a race car.

I kinda thought that was with a built block.

I should have mentioned in my first post with a stock block 281 as I have done with my stock block Camaro. I know it probably won't be possible with stock heads, valves and everything else I mentioned about my Camaro but with the factory 281 block in any case.

With some ported heads and massive cams I could see running well into the 11's. Maybe mill some material off the head to increase the static C/R (not sure about any possible PTV issues with the 3v heads) and pick up some power there. But 10's with a heavier car... Ehh, I just don't see it. At least not with the aftermarket support that is currently available.

I just read it as stock displacement. I believe he was 283 c.i. in an aluminum block w/ a cast crank, I-beams, and flat-tops.

Was he on DOT's and able to drive it out with full exhaust? If he was then even though it was a 283 that's awfully good. What was his weight?

Just ran a 10.803 @ 122.38mph last Wednesday night in the Camaro with 94% humidity air, 65 degrees. I should see some 10.6s next winter. My weight was 2920#.

He was not on DOT tires and his exhaust combo was LT's, off-road X, and Dynomax race bullets dumped. I am not 100% sure about his weight, but I know it was under 3000, for some reason 27xx seems familiar.

Nice times in the Camaro!!
