What kinda of horspower needed for 11's?

[meze1111]

What kind of hp is needed on street tires and 3.73's to hit 11's?

 

[urban96]

depends on suspension, tires, and wieght of car

 

[meze1111]

factory susp. its a 93 LX coupe. 2800ish 275 rear tires 17 inch

You could run 11s w/ 350-400 rwhp on a good set of 275 drag radials. Pulling at least 1.7 60ft and trapping over 115 mph.

when my car is finished it will have im guessing 450 crank i dont know how much exactly transfers to the wheels

 

[meze1111]

1.7 60 is tufffff on street tires rwd (03 cobra rims)

If you follow the NMRA Factory Stock class, in which the top racers will run in the 11's, most will be running at least 300 rwhp. That said, those are purpose-built cars, with a purpose-built suspensions, and with slicks. So, from that information, you might be able to extrapolate and say a full-weight street car, with street radials, might not ever reach the 11's...

Look, as the others have mentioned, you will need some sticky tires and a suspension that offers sufficient weight transfer. Someone once posted a little joke that goes something like this:

What does a 300Hp, 500Hp, and a 700Hp Turbo Supra have in common?
A 12 sec. timeslip.

The point being you can have gobs of power, but it won't mean diddly squat unless you can put it to the pavement.

 

[meze1111]

maybe i should look into some slicks

 

[25thmustang]

Actually Factory Stock cars dont use slicks...

They run on Drag Radials, and the top cars are from 330-360 rwhp. With those mods following a specific weight rule (from 3100-3400 lbs on average) the top cars run from 11.4s to 11.7s.

I have personally seen a 295 rwhp car go 11.98 @ 110 not too long ago. It is possible without huge power, but on 275 street tires it is going to be hard. I would say a set of DRs, and 400 rwhp it could be close, but still tough!

What is your engine combo going to be?

 

[meze1111]

well it might have over 400rwp might make things easier (hopefully). I definately need to be able to put the power to the ground

[mooktank]

actually you went 11.56 if you're rounding to 4 sig figs. Sorry.

 

[maverick0716]

Seriously, what is your engine combo going to be? I'm very curious now

 

[meze1111]

My engine combo is a 302 w/ forged pistons. vortec s trim supercharger 9:5:1 cmpression king cobra clutch, all new motor.. rings, bearings,oil pump etc. head work, b-303 cams aftermarket intake throttle body, injectors, control arms 3.73s subframe connectors and welded torque boxes flow master, x pipe (no cats) shorty headers, 5 lug conversion 03 cobras 17x10 front and back disc breaks all 4 ram air hood, saleen wing repainted wet black. o and this is an LX coupe. I think its the lightest 5.0?

 

[super302]

17x10 inch rims in front will be too much, good luck turning

 

[super302]

yes, the lx coupe is the lightest 5.0

 

[87fcoupe]

I ran my new combo first time (since put together in aug' 04) best was 11.68@118 mph on drag radials(nittos 275-40-17).This past saturday at a mustang event in Bradenton.I'm really happy with how it ran also next time(in January)run it with 150 shot of N20.Probally bring my slicks down with me but first try it on drag radials.

 

[nmcgrawj]

Killercanary ran a 12.18 i THINK with just a tad bit over 300rwhp and another guy over on corral actually ran a 11.98 i THINK if i recall correctly. Both in 94-95 verts that are HEAVY. Driving can be the different between a high 11-low 12 time slip and a mid 12 time slip.

 

[meze1111]

yea i might end up changing out the fronts, but i didnt because im not sure i can fit smaller tires on those rims in the front.
