well since i was feeling pretty crappy tonight decided to crank the boost to 17psi (400whp ish boost) and go look for trouble on the streets.ive found that 400whp is just stupid fast and scary in a s chassis car, like border line rediuclous.ive also come to the realization that when you can catch up to a bike in a car its proly too much power as well.........and having your tail end swing out on you is a sure fire sign that the car has too much power.......

even tho the motor and turbo can support more boost to be honest im not sure i even want to try to turn it up anymore......as it stands right now i will tune the car to 400whp and let it be, 14 for daily and 17 for overboost........yeah, should be good.just some musings for those who dont think that 400 is enough for them, trust me it is more than enough for beating up on most cars out there.

shoot 400 hp isn't enough on the drag strip, but the 400 hp on the street and the mountains/touge is way too much. But if you get on the track 400hp is great =)

I'm building an RB26 S-13 right now..... hence the name, my main name was taken.. but anywho...

I'm building my RB26-S13 and its going to have around 400rwhp... and I'm cramming as much tire under the rear as I can. Not just 7.5 like others, I'm talkin over 10-11 inches in the rear...

Of course, the whole car is going to be built... but.. I digress, everyone I've ever heard say the car will be WAY too dangerous at that power-to-weight-ratio.

But dammit, if the car is squirrely, you don't have enough rubber underneath it. My god man, if it does like you're saying, get.... more.... rubber. Stock S13's will mount 10.5 inch Mickey Thompsons in the rear with no problem whatsoever, I've seen the stuff...

And uh... 400hp is MORE than enough to obliterate any other street-going-machine on a Drag strip.

Mathematically, 400rwhp and a 2600 pound car is right at 11 seconds flat in the Quarter. Granted it would definately take practice to get the launch right, and you're going to lose a little bit to reaction, and traction all the way DOWN the strip will be a problem... but mathematically, it'd spank the dog piss out of damn near any street-going-car I could think of. Save for something pushing drastically more HP, and built for drag only.

Your damn straight, hondas can't run anything past 7 inch rims. I love my 10 in the back and 9 in the front... or 9.5 and 10.5 for that matter =D

yah, i do agree i need more tire in the back even tho i just put a fresh set of yokohama es100 245/50/16s in the rear.even with a proper lsd it still gets away from you, guess its just a matter of learning to drive the car with that much power.

how's camber in the back?

how wide are your rims? cuz you could rock some MT drag radials on the street if they fit and then dont worry about spinning ever again.

i let my friend borrow my rear rims/tires (255/50/16 on 16 x 8.5"s) at the track back in April and they work out good. pretty meaty for street.

He has the same size as your rears all around, 16x8.5 +40 -- R32 GT-R's.

On a side note, wider isn't always the answer, despite what all the domestic guys say. Contact patch size is what really matter and with a car this light and a wide tire, your contact patch is gunna be wide but very short on the street. What's needed is a better compound. A decent 275 tire will get blown away by a good 245 tire.Maybe look into some RA1's/555R's and a daily beater?

have you ever felt the compound on Mickey Thompson drag radials? They destroy any other mass produced drag radial as far as softness and traction.

For example, my friend has the same tire as me (MT 255/50/16s) on his LS1 powered RX7 and nets consistent 1.6 60 fts and has run 11.7 at 120 (NA) and 10.8 at 130 (150 shot) with them.

they do. they are 16 x 8" with +50 offset (spacer a good idea) whereas the Z32 TT rims are 16 x 8.5" +35 (no spacer required)

I have indeed. I was talking more to the rb26 kid and Carl.

(My old boss uses the MT radials on his Procharged Camaro as he can't hook up with anything less on the street...he swears by the things.)

400hp in a street car is pretty crazy, you just have to take small jumps though. I've driven 250hp imports then 300hp cars on to 350 hp cars and 400hp cars, and it's just gets old after awhile and you will want to step it up. Which is why I'm looking for 650 out of my new car.

With the new tuning changes I did to my 1.7 bar set-up I am sitting at 400 if not more whp and on my 235 BFG's they grab fine. I use them for playing around on high boost on the street and track. You don't need stupid huge wheels/tires, just the right compound.

That's my .02 cents.

Well, I'll admit, the contact patch thing would be the deciding factor.

Yes, I'll be running MT Drag Radials on the rear, and I haven't decided on the front just yet. But, like you guys have said, the ones that run MT Drag Rad's... they swear by em.

And uh, I'm not really a kid mate, I'm not old, and I'm probably in the "young" range... by most (over 25's) standards... but my S13 won't be a Street-Demon when anyone's looking.

I live in semi-backwoods West Virginia, tons of mountain roads, and absolutely no traffic on them at night. I know of more than 10 roads, within 20 miles of my house where you can sit in a lawn chair on the side of the road all night long, and see less than 10 cars from Dusk til Midnight. And from midnight til dawn... not a soul, consistently.

Personally, I think straight lines are for fast cars, and curves are for fast drivers. I'm not sayin I'm one of the best there is, but I like it. And I don't care about anyone else bein there when I hit a mountain. Ever heard George Thorogood's song "I drink alone" .... well I drive alone. *shrug*

400whp isn't a fun street car that is for sure. For the rear end kicking out on you that can be solved with some suspension tweaking out getting some et streets or slicks.

I will be hopefully rolling 500hp here before the season ends.

most of the 240 guys at the 350-400 rwhp mark are spinning so bad cuz of lack of proper camber anyways. everyone wants a lowered car first, then doesnt get RUCAs and alignment, then gets alot of power and then spins everywhere.
