200LB-FT????

[240SXer]

At 15psi, I would be scared pulling out into traffic. It would spin like crazy. I'd have to lower the power to be able to drive it normally and not be scared the tires are going to spin. And I am on 245 Nitto Drag radials. I've probably only got 320whp or so at 15psi. You need to drive a fast car first man. 200ft.lb@3k is all but pointless. But if that's your goal you're going to need to give up on this 350whp dream. Mine don't fully spool till about 4800rpm, and I've got plenty of power before spool to pull out in traffic.

There is this thing called a throttle plate, and you control it.

Really? Thanks for telling me how to drive my car. Turbos are still spikey and it's not always the easiest thing to give only part throttle while it's trying to spool. My turbo does not engage like a stock T25.

So when i'm pulling out into traffic, It's hard to think about getting the turbo to not spool so hard so the tires won't spin. The main thing is to try to keep the revs down, so having to shift into 2nd while in the middle of pulling in front of cars isnt always the most fun thing to do.

Maybe you should lower the boost in 1st gear. I thought the 25r made boost earlier I guess. Or does it make none and then make 15psi over a couple hundred rpm?

I'm comparing your driving eperience with mine. I have a ca & t28 and I can pretty much decide exactly what boost I want by pressing in or releasing the pedal. When I start to build boost I can cut it down from 14 to say 5 psi or whatever I want. My brother's car is the same way. You have another buffer with the clutch controlling the power. Granted, I'm probably 100hp shy of you, but my brother pretty close.

I do see what you mean, the power is harder to anticipate. I ride the clutch a bit before pulling out to determine how much gas to give it when I pull out. Maybe I'm just a slow driver compared to alot of people.

Lol, ya, it makes all the boost between 4400-4800rpm. I have the .86 a/r. It's a laggy mofo.

Like for example the other way I was trying to get ahead of some cars to get onto the freeway, I floored it, when it hit about 5k the tires started spinning, so I shifted, and it stayed in the boost so I shifted again. I'll grant I was miles ahead of the other cars by then. But basically you can't just carelessly take off. I suppose my turbo is bad and probably what a lot of people don't like for that reason.

I do drive fast and I like taking off fast to get in front of people and stuff, it's easier with more power, but it's also harder with more power if that makes any sense.

I see. Maybe try advancing your timing up to 4400 rpm. I also have a .86 a/r turbine (gtir t28) and I see about 1-3 psi really early, under 2500 rpm, then I see about 5 psi around 3300, then it only increases up to about 7 psi until about 3800 rpm, then it shoots up to max boost.

The other car I was talking about driving is an rx7, rotary's a different animal. He sees boost pretty much anywhere about 2k (non-sequential) but that wasn't a fair comparison, it spools turbos more like a rb25 does.

everybody just stop entertaining this guy.: ) pushnlacs dont know ****. for #1 he dont have a 240sx. # 2 he never drives a ka-t or an sr20det. #3 i dont know wat the hell hes trying to do with a 400 hp crank 240sx maybe race it on street and get his 15 sec fame on the TV news.

Damn, out with the hateraide... lol.

Hey I may get yelled at for this but the topic caught my eye and my curiosity. I looked up some dyno charts and seems that what you want(200lb-ft@3000) is kind of unreal coming out of a SR or a 4cylinder for that matter.I looked at 4's 6's and 8's and it seems your gonna need at least I6

First a 2JZ(Supra) which peaked 506lb-ft@5k. It made 280@3k @23psi. That's a straight 6, that is torquey by nature, thats running 23psi and is 80lb-past your goal.

SCC's silvia w/ a disco potato is putting down 175lb-ft @3k. It maxed out: [email protected] a KA-T could do it. I4's just have to rev to make power, simply stated you may wanna look for another motor...
