Re: 439whp 312tq RSX 25psi Turbo street driven on 93 oct. (rewsnaeht)
why does everybody keep makin faces at the 439hp @ 25psi? lol. this is pump gas yall, dont forget. 25 psi is really pushin it on pump gas. turbo size plays a factor as well.

that is why i prefer the dynapack system. no tire slippage, more reliable results.

i would just like to say that this statment is pure ignorance. Your acting like boost pressure is relative to hp. DOH! silly ricer.

Boost pressure is related to horsepower.
Care to explain how the two are unrelated?
What is not related is the octane of the fuel. If you must use lower octane fuel, lower the boost. Quite frankly I don't see why anyone would brag about these numbers. One can make just as much power with less boost and better tuning, and still be able to run on 93 octane.

well dependent on fuel and ignition tuning - utilizing the same boost, a car could have WAY different HP ratings - as seen in the Evo. i guess that would make boost and horsepower un-related, im just sayin.
"you could make just as much power with less boost and better tuning" whats your point, they chose to do it with more boost less tuning..... would it have made you feel better if they made 440 @ 22psi (but with a bigger turbo) instead of 25psi?
ive yet to see a 2 liter break ~ 440 wheel horsepower on pump gas, i guess all yall that think its not a big deal or its just another normal rsx, yall must know some big juice cars.

Yes, I realise this. I know that there is no linear relationship between the two that allows one to say, "X lbs. of boost = Y hp," however they are related. And with 25 lbs. of boost I'd expect more power.
On a street-driven car I would choose to run lower boost and more precise tuning. When I owned a turbocharged car this was the philosophy I followed. It has stuck with me. One of my friends recently tuned a turbocharged B18C which is producing 410 whp on less than 15 lbs. of boost. It also has a nice, flat torque curve, runs on pump gas and runs smoothly. How? With 10:1 compression and very precise tuning.

Re: 439whp 312tq RSX 25psi Turbo street driven on 93 oct. (MK Ultra)
25psi mean nothing absoluelty nothing other then block can stay together under extreme amount of pressure. CFM's is what makes power. U can have a smaller turbo. like a t3/t4 pushing a 25psi making like 450ish whp. Or you can have a t66 at 12-15psi and doing that at a much more effecient boost level. DOH! Pressure is only really releative if your talking about the same turbo. So when someone says it only mad such and such power at 25psi? hell it could be a small *** turbo maxed out at 25psi and that would be great power for it, but not something bigger. So hence 'pressure' doesn't directly relate to horse power. CFM's is the only thing that matters how many cfm's is pushing then the ammount of pressure.

there are several dsm around here that make that power on pump gas. but i agree with you man. Its a awsome *** car. And to the people that hink thats a bad number for that psi i bet don't own a turbo car.

Re: 439whp 312tq RSX 25psi Turbo street driven on 93 oct. (HolyWater)
Those are some good points, however I have a couple of my own to make.
First, yes, you could run a lot of pressure with a small turbo, but why? The only reasons would be for a torque curve that is biased more toward the low end, yet judging by that graph this is not the case with the setup in question. I may be wrong, but that does not look like the curve of a tiny turbo choking on high boost at high RPM.
Pushing a lot of air through a small turbo has some drawbacks. For one, by compressing the air less efficiently you add unnecessary heat. Not just to the intake charge but also to the engine bay. If I were turbocharging a K-series car I'd probably want to be careful with that, given the location of the turbocharger. Another thing to consider is how fast you want that turbine to be spinning. By using lower boost with a larger housing you should see a longer life for the turbo.

Re: 439whp 312tq RSX 25psi Turbo street driven on 93 oct. (MK Ultra)
without doing a internet search id like to know is that engine able to handle the power with any of the following stock, pistons, rods, or cylinder walls. id guess it would have to have better rods and pistons but what about the walls. does that k20 or whatever it is have the cylinder walls like a b-series or is it crazy strong like a 4g63. id like to know i havent done any learning on this engine yet. thanks

Re: (senna1)
Ehhh... it seems slow on the street. What good is all that damn power if you can't do anything with?
I bet that I, with almost no dragracing skills, could keep ahead of that thing until 80-90mph.
Ohh... I forgot though, it has 440whp.. on 25psi. That means it is cool, even if it can't go anywhere when it is travelling below 90mph. Worse than a 700rwhp Supra running 12's!

The LSD is on it's way, 1320 will follow. Oh and btw the engine makes power so easily ( less recipricating weight) that there is virtually no down time (lag) between ratios 1,2,3,4,5,6. With the LSD and some R's and the pakage for this car will be complete. But it's fun to drive anyway..... better than 1000 cc superbike type acceleration is no joke.

no hating here, ive yet to even see a turbo rsx here in NJ,, so way to go, i hear the fuel system is a bitch to play with and tune,, good **** though,,,every time i see another rsx, they grow on me,, honda better figure out how they are gonna compete with all the stock turbo charged cars coming out,, i know everybody is seeing how MOPAR is tryin to **** on everybody in the industry now????damn this thing keeps gettin bigger!!!

Sorry bro, but 25 psi doesn't mean anything. Do you know what size the turbo is? If not then you have no ground to stand on with your statement. Good numbers guys!

i will bet that the members who say this car is not impressive don't drive 440HP cars. i would like to hear more about his 1/4 times when he gets a good way to get the HP to the ground. Nice car....i don't even care if some say that there was a 'better' way to do it.

Word my brother. The whole world is full of skeptics. We will soon have the time to distance numbers. "Don't touch that dial". (poof)
