ok with a 2200-2400 pound car you would need about 145-165 horsepower (at the wheels?)to get a 14.4 timeslip @ 95mph.

this, as far as I know, is not doable with a stock port, even if we're talking good intake and exhaust.

I do not think that a street port with a nikki can get over 180 at the motor.

peejay says he got 135hp on his stock carb street port. I forget if that is at the wheels though.

that all said I do beleive a 12a can beat a Cobra. If the 7 driver is good and the 'stang driver cannot drive.

Just my $.02, somebody tell me if my numbers or thoeries are wrong.

Those are stock weights of an RX-7. If the car weighed 1900 lbs, how much would you need, then?

Oh shit then what am I gonna run at 275hp in a 2400lb car + my fat butt? :) Holy shit, im starting to get anxious now, and if anyone wonders why the hell I sit the whole weekend on this forum, well I got my 4 year old and we tried that 'play in the garage while daddy works on the motor' Well turned my back and he was trying to put a stick in the air intake. Rounded up my 4 year old and headed back in the house :) Be glad when he gets a wee bit older he will become a GREAT helper ... Just right now, i dont feel like fetching nuts/bolts/sticks outta the motor :( Anyone blame me?

a car weighing 1900 lbs needs
125 hp to pull off a 14.43 @ 94 mph.

anyone care to tell me i havent added 25 hp to my engine?

V8kilr 03-17-02 06:00 PM

oh my weight was 130 then im at 125 now.

mar3 03-17-02 09:07 PM

I think you need to leave it at that and also write down the threadid # so that the next time this crap starts up you can simply tell the critics to shut up and hit the link....;)

mike,

When I used cartest I came up with these numbers for my project.

I would expect a 0-60 in the high 4 sec range, running the 1/4 in high 12's low 13's and a top end of 160 - 170 mph.

I used this on cartest assuming 2300 lb FB and using an average of turbo 7 dynosheets.

im 5'11"

normally weigh 135-140 but ive been very very stressed lately,
havent been eating good.
it seems like ive been only getting one descent meal a day,
weighed myself today at 124 lbs
with digital scale and still had all my clothes on with my big jacket.

the worst part is im a medium bone frame,so you can only imagine,
i look like a cocaine addict right now,

well thats enough of that.

that should be at the rear wheels, you would have to have way more than 25 more horses, at 25% loss more like 60.

I still dunno about a 160hp stock port 12a.

SilverRocket 03-18-02 07:51 AM

Good job with the timeslip V8kllr, I retract the flag lol. I agree that you've likely got somekinda ported motor in there...


at 25% loss
Yaya,

I'm pretty sure rotaries usually have rather small percentage losses. Look at the FD, 255 flywheel and usually 220-230 to the wheels stock. The SCC FB project car put down a really good number stock too, I can't remember exactly but I think it was approx. 95 to the wheels. So he might only need around 140-145 flywheel to make 125 to the wheels. That IS definitely possible with a stock port, albeit not likely with a stock carb.

That said though, are you assuming a 1900 weight with driver? That is very light indeed, but I know nothing about lightening FBs so I won't comment.


i look like a cocaine addict right now,
Hehehe me too man... I've been sick for 2 weeks and have been going like a mofo writing exams and papers for a month. I'm normally around 160 but I feel like about 140 right now lol.

5' 8" and 168 lbs...sounds like you've got a baseball player build. You we're killing me with the tales of working in the garage with your 4 yr. old. I keep telling my wife that the boy's gotta stay inside when I'm in the garage "working." He's just short of 2.....:cool:

---> yayarx7, auto trannies suffer that kind of parasitic drag loss from friction. Stick cars generally won't unless they're running a combo that has a ton of extra weight for durability introduced into the drivetrain, ie., Jericho tranny, Moser axles, heavy drag slicks, etc., all at the same time...

Man you all are making me feel bad! I am only 14 Yrs old, weigh 196, at 5' 7"! I need to go on diet :D So NO you are NOT the only 'BIG BOY' here :D LATERZ,

HOLY CRAP, that would be awesome, this is one of these things I dont know what the hell im getting into before I do it. Reminds me of my buddy and the blazer he wanted a lot of bass and we did 8 12" JL W3's and we got a vehicle we couldnt ride in, felt like someone was jabbing a pencil in my ear, I mean IT HURT!

Well I was at work and seen an FC I dont wanna race... DONT FLAME HIM, he was really cool. Hes got a small block Chevy built to the HILT. I bet this car is fast, I got some pics of it, but this is probally not the right forum for em.

I think maybe I need some MORE STRESS, i could stand loosing my beer gut I have accumulated :)

Oh and Mar3, he also threw a piece of gravel into the air intake hose, I got it out, but damn he PISSED daddy off. Put it this way he wont ever touch it again, he knows better now :)

RotorMotorDriver 03-18-02 04:39 PM

spoolin 03-18-02 11:53 PM

82transam 03-19-02 07:04 PM

I'm 17 6'-3" 210 lbs, also "perfectly ratioed" I'm the quiet tough guy at school, no one fucks with me. :D Everyone who sees my car wonders how the hell I fit in it, I'll tell ya how my hair rubs the damn headliner and my right knee hits both the steering wheel and parking brake. I don't care it's worth it first gen's are the coolest car ever made, hands down. :D :D :D
