How much hp/tq to get into the 13s?

[ZiG]

Just curious.. I am shooting for a 13 second car but I don't know what that means in terms of horsepower and torque. Assume decent street tires and no weight reduction on (of course) a KA-T. Oh and it's an s13.

edit: Oh, according to those online calculator things, looks like 240-300

I'd say low 200s with good driver and tires.

[yellow2000SR]

mid to high 200 range just like those "online calculator things" say.

Thats at least what power it takes for a Ford Escort ZX2 to get into the 13s and they are just a little heavier than a 240 (granted they are FWD).

[S13FX]

Only reason your probably going to be stuck at low 13's in the 300's is cause of wheel spin.

But on my SOHC with a GT32, 8.75 PSI, I was hitting around the 300 tq mark easily and had wheel spin like a mofo.

Get your self some decent suspension doesn't have to be coil overs. Get at least a 245 tire in the rear, and a good clutch, practice your lunching and with 250 - 300 you will run 13's all day.

[bone_stock_240]

practice your lunching

I am great at that.

[S13FX]

I am great at that.

HAHA d!ck, I meant Launching

[ZiG]

Ok, great. Glad to hear those numbers sounded right to everyone else.. Don't know what I'm doing for suspension yet.. Coilovers are a little priecy for my college student budget right now, but I'm watching for used ones all the time..

[GEO]

190 - 210rwhp.

[bone_stock_240]

HAHA d!ck, I meant Launching

Oh ****, forget it then. I will never succeed at the drag strip in that case.

[ZiG]

Yeah, more lunching = worse launching. It's a proven fact.

My wife jokes that I'm skinny for weight reduction. 5-8 at only 130...

[Nismochop95]

why dont you just make a hp goad of 250 and ain for 12's

[Florida240sx]

Got to have suspension to allow oyu to use your power otherwise you'll bog or just spin. I had a blown hg with a 2.8 60' and then car finailly started spooling and ran a 14.4 @106mph Imagine if my car didn't have a blown HG and had a good launch. there is .8 seocnds lost off the launch not to mention how much power I wa slosing from the hg and it affecting spool and spark etc.

[Chezedik]

But Florida has had the worst luck ever, except for maybe SunnyS14. He should have been running better.

[boznuttz]

Are we talking about times with the stock R200 here?

[ZiG]

Well, vlsd, but yeah.

[boznuttz]

If it's in good condition and maintained, the R200Vs aren't that bad at all. I'd say low 200s on decent street tires.

[Chezedik]

F that, the R200 is a great unit, but it is better when it locks.

[frosti108]

im doin a mild turbo setup on my single, with a z31 T3 with 7 to 10psi... gonna weld the rear shut, and eventually run some slicks or drag radials on the back. but until then i just have some 225 55 17s. should be good for 13s

[Chezedik]

Especially if that is all you want (not turning).

EDIT: BTW, that will not get you into 13's unless you are a seriously good driver, expect 14's.

[Florida240sx]

I've had worse luck than Sunny I beleive. LAst year Nopi melted my brakes master cylinder on the way.... Finially arrived to Nopi to find my alternator sitting in my engine bay being held by the belt. The bolts were missing!!!!!!!And at the time of ocmign to Nopi both ym cams were off one tooth and I couldn't go over 5500rpms. Car was making 160hp 198ftlb at 10psi....Fixed that and find out my cometiv HG is leaking while I was at the track.Got a new valve job done on my head and should be firing her up next week

[Chezedik]

Yeah, you have had some serious bad luck. No offense, but it does make me feel better about my bad luck...

[frosti108]

as much as i would like to run the open for the twisties, i wont be able to put any power down with the turbo setup. good luck sqeezing good times out of a peg leg car i guess ill just have to get into drifting lol

and dont tell me what to expect... im very set on 13s. this car will be gutted welded, hookin and runnin like a raped ape. its going 13s. thanks for the thought, but bring your pessemist **** somewhere else

edit: oh and im a great driver

[Chezedik]

My pessimest ****? Have you ran that turbo? I know plenty who have, and I had a variant. I am not doubting your ability, but the stats don't lie, that will not likely be enough power unless you are willing to drop a mess of weight, which you may be, but you won't like driving the car. I wish you the best of luck, but I don't forsee it. I would tell you to take it as one man's opinion, but you already have. Good luck.

[kazuma]

I have a friend running a z31 turbo at 8.5psi on a built engine and he put down 247whp at 5100rpm. I think that should be more than enough to get into the 13's as long as the launch is good.

EDIT: its a 8.8:1 compression built using AMS parts.

[Chezedik]

Well, that is impressive, and like I say I wish you the best. I think your greatest advantage will be the very fast spool. I suggest rebuilding and balancing the assembly.

I did that, and with the T04b housing, I was at full boost at 3100, very nice! The engine was **** though, so it came apart. I would also suggest upping compression slightly if you are wanting faster spool, but be VERY careful. Also, this will eventually keep you from running higher boost, so that is another decision to make. But it will be an SR killer. All the best.

I agree about not being able to run higher boost but thats why I bought that v trim turbo from you :p lol I still havent put it on since mine hasnt fully crapped out yet and I dont have access to a welder to weld the flange on my current pipe.

my friend gets full boost(8.5) by 2700-2800 rpm but his gives out at about 5500rpm.

[spooled240]

IMO, good tires and an open diff can still get you in the 13's if you can make up for the sorry *** launch with some crazy top end power. Turbos are better off when the car is already rolling ...just my 0.02

[Chezedik]

Oh, no kidding. What do you think, I did good right? The only thing I would do different is go with a larger turbine wheel.

[480sx]

Yeah, you have had some serious bad luck. No offense, but it does make me feel better about my bad luck...

Oww. Well i have three spare Ka's lying around for my learning curve, and or bad luck.

Seriously though, theres no set HP number thats going to guarantee a timeslip. It has more to do with your ability to put down the power(LSD, suspension, ect), and your hp/weight ratio.

Iv got a stock s13 thats completely gutted with a FMIC running 8.5 in the 8th. Thats 230 hp getting you realllyyy close to a 13 sec quarter. If it wernt striped and gutted i wouldnt be nearly that fast.

[Chezedik]

IDK, Having an interior is nice.
