and BTW osoboosted i'm sure the rsx you raced was quite or nearly stock.....good kill though
I'm talking about a 7thgen with a k20 and 240whp vs a 7thgen boosted with 230whp....i've spent a lot of time at the track and I don't see how a D17 is gonna run a better time with those numbers....I have a friend that is running 13.2s with a 6thgen with 200whp Naturally Aspirated....lsvtec....and my best friend has an SE-R 200sx boosted SR20DET putting 260 at the wheel and his best is a 13.4 at 109........how is a 230whp boosted car that is running a corrected 13.4? 13.2? whatever going to take a 240whp naturally aspirated car??? The 60 foot times would be no where close to each other........I'm not flaming I just want an explanation....

Here is the explanation....

Look at the torque CURVE of an NA car vs. a Turbo car. The turbo car will almost ALWAYS have a better torque curve. So if you are making the same exact numbers, the turbo car will always win. You really cant lose with a turbo.... It creates the right amount of back pressure for the car to have low end torque, then it force feeds the car at mid-high end to make more overall torque and power.

Turbo cars have really nice, smooth torque curves (if they have the correct combo, tuned right, etc.) When NA cars usually dont.

Dont get me wrong, an NA car can be tuned to have a nice torque curve, but when you tune an NA car to be like that, you usually lose high end power.

I wish i had the dyno of my car with the air-water intercooler, it was a PERFECT example of this....
I made 185 whp and 200 ft/lbs on 7 psi, with a blown head gasket (blew it on the way to the dyno, and yes, i felt stupid)

Usually if a turbo car makes the same whp as an NA car, the turbo car will make more torque.

Usually if a turbo car makes the same whp as an NA car, the turbo car will make more torque.
to combat the loss of high end torque, systems that dynamically change the valve timing are introduced. Look at the porsche continuously variable timing system. if you took a 240whp motor with a timing system like that, i would bet it would outrun a turboed 230whp motor. I dont know if that toda rsxs used its vtec-killer camshafts, but the regular i-vtec system should be enough with the higher power to make it out run the turbo d17. the rsxs has a higher redline, and can wind out the gears without being forced to change them.

this was how my friend beat me with his 00 si (when i had my 2k1). he gained NO ground on me (we were dead even), and actually started to loose ground until i hit my 7k rpm shift point while he kept going in 1st.

Hmmmm....what I have said has just been my experiences....
From what I've seen most NA cars will rip a turbo car out of the hole but then the turbo car quickly reals them in....so they might both run say a 13.4 but one of them at 100 and one at 109(turbo)....
I want to see a dyno sheet catalyst, not that I don't believe you but 184whp and 200ft/lbs would be the first honda engine I have ever seen making more torque then hp which is truly remarkable.....

i can get an intercooler for 300 bucks that 1500 is really a good price compared to 3100 and its street legal I must add.

My civic made more torque than hp the first time i dyno'd it.

And about the launches, i take everyone off the line, no matter what they have. The launch is all in the driving.

I suppose you can take an EVO or an awd car off the line to....
I'm sorry I have to disagree with the turbo vs NA but that is purely based on my experiences, real experiences....

it all depends on the driver. I pull off consistent 2.0 60/ft times. If you look at the sport compact that has the "24 hours with evo" article in it, he was pulling off 2.4, 2.3, then the occasional 1.8. It is all in the driving. I consider myself a good driver. I spend my entire day building, and testing turbo cars. And i dont do it with your everyday mechanic.... I test cars with drivers such as Dave Hickman. Hell, every time i go to the track Dave comes out with me, so i have been around the best.

But yea, you put your every day guy in an AWD car, and i will most likely beat them off the line. I proved that to my friend in his Eclipse GSX (new manifold, new T3, new piping, front mount, 3" downpipe and exhaust). Until he blew his tranny trying to beat me, we raced just about every day. And i never lost to him.

And AWD cars are harder to launch.... you dont just rev them up and side-step the clutch like most people think.

And i base these off of my experiences....... the ones i got from designing, developing, building, installing, and driving turbo cars.


Not trying to sound like a d*ck, but i do have SFpower and Dave Hickman standing behind me as i am typing this.

its true, reving up and droping the clutch isnt a good way to launch awd, slipping is best. however when you are pushing 350 hp at the crank you will destroy your differentials if you dont get the power through to the wheels to cause them to spin. a lot of people say its best to rev to 3k, hold at engagement, then rev to 5k and drop to allow spin.

i have an auto though, so id go up to the ~3k stall speed, and just let my foot off the brake. bad for my differentials yes, but great 60 ft times id say.

I ran a 2.2 3 times straight with my NA setup, Yokohama Parad Spec-2s (215/40/17) on my 17" ADRs. Ran 2.4s on my firestones lol.

I am really impressed with the 2.0 times especially with azenis since there sidewalls are so stiff and can easily cause lots of wheel hop. I know in my Turbo hatch I was only able to muster 2.2s on the 60ft. Do you happen to have any time slips of those runs you can post.

whats the tire psi when you run? I have falken azenis st-115's and my best 60ft. is 2.3 .
I have it lowered to 20-22 psi. I get less wheel spin that way. Running on 17" wouldn't have anything to do with 60 ft's right?
