Now Indeed you may make more torque but inversely percentage wise the numbers are not as large and the amount of Torque to HP is going to be less i.e. A engine with a turbo that spools instantly will put out a lot of bottom end torque with a fair amount HP vs a engine with a turbo that does not spool till 4k will have lost bottom end torque which is importing for getting off the line. Not everyone wants to twist their engine to 4k and dump the clutch. LOL.

Now percentage wise those Torque numbers will be greater in ratio to the HP numbers than with a larger Turbo. So your torque numbers while being larger will not be so much larger in relation to the gain in HP numbers. Sure you might gain some torque with the larger turbo but is it in the optimum power band were its useful? Anytime you lose bottom end power you lose torque and you lose it in the useable range.

Your 2 step rev limiter is merely a stop gap fix to the facts above.

P.S. don't try to bring the big turbo's of diesel trucks on me either. Diesel trucks have large turbo's because they have extremely large displacement engines and pistons for the sake of torque and need a big turbo to push that. Oh and the large turbo's on those engines spool quickly in relation to the size of the engine thereby building massive torque.

What's an useable range for you? I guarantee you my useable range is alot different than yours. I'm happy with my 4500 - 9000 RPM power band. It's not like I drive around trying to race people at 2,000 RPM so why would I want my torque band that low anyways? More towing power when I'm hauling back food from the commissary?

Im going to be using anti-lag on the Haltech on a switch on the shifter if I drop far out of boost at the twisty track.

when configured right its great, you just hold it down for a second, let go and your up to full boost.

Boostage · 09-26-2007, 02:47 PM

Koopa a 180 whp civic sacared you? Im confused because you listed some pretty powerful setups. btw, before my s14 I had a fully built turbo civic. and it wasnt scary under 200.

You live in a different world my friend where bottom end torque is not as important. to much time in oki for you. lol most the cars there are gutless wonders in the bottom end department short of skylines aka 6 cylinder machines. Hell stock SR's are disgrace in the bottom end department unless they are S14 or S15 SR's and even then its nominal.
Here in states people drive cars with lots of bottom end torque that move at 2k with a blink. Don't get me wrong I like revs but not at the sacrifice of off the line power.

steve shadows · 09-26-2007, 02:48 PM

one of the scariest cars i was in was a 200whp, all motor EK, little sleeper like 3 years ago.

probably because it felt like it was going fall apart and kill me.

haha

it was kind of fast though

Koopa Troopa · 09-26-2007, 02:52 PM

Yes, it literally scared the shit out of me. We had to stop at a Maku Donarudo so I could make dookie.

Fun times... I contemplate dumping the 14 for a CTR every week now..

Most the cars there would embarass the majority of cars in the states. All you hear Friday night at a stop light is twin plate clutches singing. 400+ WHP at the local drags is the norm, hell there were two S13's with t88's the last time I was there.

You're still not getting the point I'm making about 2 steps...

To Civic dude - 180whp EG6 doing 150 kp/h through this turn is pretty scary

Boostage · 09-26-2007, 03:05 PM

so toy you a 180who civic hatch pulls harder than a 450rwhp s14??

Koopa Troopa · 09-26-2007, 03:13 PM

No but it's alot faster down some roads. Hell that Civic would beat the piss out of my old 180 with 256 cams and .9kg boost on a t25.

wntrcoatblu240 · 09-26-2007, 03:13 PM

i'm really glad to hear that most people on this thread thinks that 350 is plenty fast... i was getting tired of hearing from people that it wasn't enough, blah blah blah... usable power with traction imo is a perfect DD... i had a friend with a 500rwhp supra and i know for a fact that even with 285 tires in the rear, he wasn't able to use all of the power that he had available on the streets...

steve shadows · 09-26-2007, 03:25 PM

it really is taste, driving style, type of racing also.

Im still debating on switching to a gt35r again in the future, lag really doesnt bother me much, I just want a 3k burst power band with 500whp.

The gt3076r can do it a with almost a 4k power band but with substantially more cyl pressure/boost, rather than cfm.

Anti-lag -road course

2-step- drag race

I use the 2-step sometimes, when that spot on my map is configured right I can dump the clutch at 6k, with a full 14 psi of boost already pre-loaded on the motor and rip through 1st in literally 1.6 seconds.

Kuzumi · 09-26-2007, 03:38 PM

i always wanted to have high hp(500+) but then i got looking around and realized that everything cost an arm and a leg. I also talked to a guy with 550hp in his fastback and he said it is almost unstreetable.
my goal now is more reasonable(325-340)

$3500 LS1 swap ftw

whiterps13 · 09-26-2007, 03:59 PM

I drive an NA KA pushing maybe 170whp at the absolute most.

Riding in Broadfields 400hp/300tq SR'd coupe for the first time serious left me speechless. I was gripping the 'oh shit' handle so hard my knucles were white with my feet pressing so hard on the floorboard Im surprised I didnt push it through the firewall. Scared me damn near shitless.

Its all relative, but then again spinning 275 Toyo R1's at 60+mph is just stupid no matter who you are.

jeeper_x · 09-26-2007, 04:46 PM

i have ridden in a daily driven T88 2jz Cefiro in Thailand....it was fine cruising on the street and also was pretty damn fucking fast when he put it down on the motorway....

2bad240 · 09-26-2007, 05:13 PM

i made 330 with 2871r in my s13, im around 2600 pounds, my car is pretty fast, i now have a holset hy35, and i am shooting for around 490.

But for the true car nut, who actually put time and money into making that kind of power, do think its plenty power? a buddy of mine has a 620hp supra, too me that feels about as much as you would ever want on the street, but his car weighed in over 3750 lbs. and had 285 Pirelli's I figure an s14 clocking in under 2900 lbs should feel similar with less power

I am almost done with my project and maybe Im warped by huge numbers on the internet, but now I am thinking 350-375hp might leave alot more to be desired, when I initially set my goal I figured it would give me the crazy acceleration. how does this much power feel to you guys? do you want more, or is it just too much for you?

#1) You live in Florida? You need horsepower. Not because you personally need it, but because everyone else HAS it and all the roads are straight. Every fucking video I see of Florida racers is of late night highway racing, THATS IT. Its fucking pathetic if you ask me, but thats Florida for you.

#2) Design your car for the type of terrain its driven on. There's no such thing as a swiss-blade car, that is fast in every aspect. There are attributes that can help make a good car a great car, like making it lighter - but a canyon car will never make a good highway car, vise-versa.

I've driven so many different types of cars, all different characteristics. I'm obviously afan of the light-weights, since I only care about canyon racing. High horsepower has never interested me, although it does feel nice having it when you're on the highway. To me, response is everything.

Dave Longo said it, and said it best. Response. The *BEST* cars are the ones with the most response. I could give a flying fuck what your peak HP is, because that means nothing.

Another ultimate factor that is commonly overlooked is tire compound, which everyone seems to forget. The limit of adhesion is here, and if its not THE BEST then you're big power numbers also mean nothing.

Last is your driving style. To everyone posting big numbers, lets see how good you are at controlling it. Most people over-estimate themselves and dont understand how "in-tune" one must be in not only driving, but also maintaining their beast. Like I said, its one thing to control a 300HP on the highway (big deal, press the gas.. even Nick Hogan could do that).. but its another thing to control that shit AT THE LIMIT when you're on a mountain side. One mistake is all it takes.

---

For me, depending on the weight of the car, 200-300HP is MORE than sufficient for a good canyon car. For highway, you'll want more than that.

i had a 194whp Ek and it was fast, but not nearly as fun as my sr 240 was. straight line i think the civic would have won.

citystars403 · 09-26-2007, 05:45 PM

im with "Drift Freaq" on that big turbo less tq issue....other than that 290 awhp on my 95 gsx w/ Big 16g and other goodies at 13psi and weighing in at between 2800-2900lbs. left 30ft awd peelout marks and gave me a rush everytime i ran it...im thinking 350rwhp on a 2700lb 240 should not only give major traction issues but leave a nice smile on ur face after 2nd gear!

Tearlessj · 09-26-2007, 06:22 PM

I drove my friends 170hp civic and I thought it was damn fast.

I guess its all about experience, for me, I have never driven a car that was that quick. To some of my other friends they said it was slow.

On another note, at what HP rating does a 2871R max out at on a SR?

bing · 09-26-2007, 08:30 PM

i commute and daily drive about 100 miles or more everyday in my S13 with 325whp, full coilover, multi-link, solid aluminum subframe bushings, etc. etc. (approx 6-7000 miles in 4 months)

it totally depends on your frame of reference.. people in the office think i'm absolutely off my rocker... my boss will not get into the car with me and when i drive colleagues around they think it's hilarious how harsh it is...

but if you are used to these things then you always want a bit more.

plus, turbo cars fluctuate when it get super hot and humid versus when its awesome chilly out.

on hot days i ram it and i'm like: "where go'ed the poworz?"

on cool evenings is awesome..

i'll be upping the boost in looking for just under 350whp for street... i'll crash it before i hit 400whp i'm sure

Nice lighting in the pic.

I thought about getting an EG6 a while back...touge monster. Too bad touge and most of America don't go together. I sure in hell know touge and Michigan don't go together.
180fwhp is a good bit in a 1800lb. car. I definitely would have needed an 'oh shit' bar to hold on to. Good that the road's smooth as silk, cause if it were the other way around...

I'm glad everyone is satisfied with 350rwhp. I'm planning on going with the ever so popular gt28 myself. On the other hand, I can't wait to feel 450+awhp launches in my friend's 35r STi next year...

steve shadows · 09-26-2007, 09:24 PM

ifixi is right

b16 eg best canyon car

...or maybe im serious.

I woudnt want to street race my 420 whp car on a canyon road, at least not yet.

WSIR, sure.

watch me pass on the straights, but catch me in the corners.

Agreed. Majority of cars on the road I race has a stock or close to stock motor.

sideview_180sx · 09-26-2007, 09:47 PM

ixfxi has listed very good facts. especially building a car to your surroundings. And repsonse is everything. Besides on FA guys have posted vids of them on a race track passing up c5/c6 vettes. and the s13 is only putting down 350-375whp. Everyone relying on HP numbers yet forget weight is a major variable.

bigOdom1 · 09-26-2007, 09:55 PM

im fat 300 doesn't feel like enough doubt 350 will hopefully the 400 range will start to scare me a little more

LB.Motoring · 09-26-2007, 09:59 PM

Is 350-375rwhp fast?

in a S chassis,

pretty much the end of street power,

I wouldnt see why you would do anymore for street terms.

whereda40at · 09-26-2007, 10:23 PM

yea i agree its all what you want and what is around you. and if you want to be a track car for drag, imo i dont think its enough cause all the cars around me that are for track run low 10's to mid 9's on average. we have alot of 400hp+ dd cars in my area so its all realy how you look at what you want to be a street car or dd.
