he doesnt need better tuning.......it was tuned by one of the best aem tuners in the world.....this guy fly's all over the place to tune aem equiped cars....he is sean mcelderly from tourquefreaks....and the reason i know is becuase i went with him to go pick it up at tourquefreaks

theres video of him doing a 10.68@140 1/4, i've been trying to get him to race some R1's those caliber type bikes, but i'm pretty sure he'll race them when it is up from its major heart surgery , there is a father/son team that race at our local track, both of them own HIGHLY MODDED hyabusas, one w/ nitrous trappin at 160mph and one turboed trappin at 158, and cant wait to see when he tears both of them down

I guess my definition of tuning is different than others, when I think tuning I don't just think the fuel and ignition, I think proper turbo sizing, proper head flow and cams, and anything else related. There is only so much to be gained from fuel and ignition timing, poor turbo choice is a big factory on an engine like that.

My ***** is the engine while making pissloads of hp (and torque), has such a narrow powerband it's not very useful for much more than bragging rights. U should be able to hit full boost and hold torque before it falls off. Look at the (stock)5 cylinder volvo's and many (stock)audi's. they dont' report a peak torque @ only a certain rpm, they report a torque range (volvo I believe was 238 @1500-4000rpms).
BTW I'm aware of the power and torque falling off when u let off the throttle. He didn't let off the throttle when he hit peak torque, he let off at around 7000rpms. I noted how he hits full boost and torque and then looses power from there,I meant torque. I properly built turbo motor should have atleast a few rpms of a HOLDING (near) peak torque, see those engines I mentioned above.

Also they don't show the fuel curve on that dyno, so I can't tell how "well" tuned it is. as far as I'm concerned that is a poorley setup engine.

the a/f is set to 11.1.....and on another note...all that was done through a 2"3/4 downpipe

thats all fine and dandy but it's still nothing but a dyno queen. Any decent engine builder wouldn't want to use that in their race car.

why dont your post some pictures on your um.....insane dsm. did you mix up the numbers??? perhaps its has 089 hp instead and you added the 0 infront cause your a retard, cause i highly doubt you have a car with nearly 900hp but all you have to do is post pics and i will shut up.

um...maybe thats why those insane solara's use it......titan uses it in their celica as well, there is a n20 company that use it in their tacoma and are running some low ass times...........


ok.....what decent engine builders are running 5 cylinder volvo and audi engines that are as fast if not faster than one of the cars above using the 2jz-gte...once again

i also found it kind of odd.......he says he's got a 2.4l stroker and is revving it to 10.5k rpm .....that somehow doesnt make sense....its hard to rev that high on a 2.0l

[thedguy]

look in scandinavia U'll find plenty of quick volvo's and audi's. Check out a company colled evolve they make pretty damn nice volvo's. Also Dahlback racing does some nice audi's. And I never said they were going for the power this guy did, but that the stock setup shows what a properly done turbo engine should be like.

And who's to say Titan or other racers aren't using the same turbo but using a better setup? Something tells me titan has a certain set of cams they run, I KNOW they have their heads ported and flowbenched, I got a video when they interview the guy putting hte motor together. They also are probably reving the engine out higher. If your still just blabbing on about the A/F's there's more to engine tuning/building than just a/f's and ignition timing.

Again My complaint with this guys setup is that the engine is poorly setup. All he did was try and get the highest HP number. A good race engine might use the same turbo and 2jz engine and head. But I bet they are also running special cams, properly sized exhaust, well designed header, a good set of cams to take advantage of the turbo in it's effeciency range, custom intake manifold thats also tuned better for their needs.

if U go look at dyno sheets from engines built by people who know what they are doing, u'll see that when they hit full boost, they actually have a torque curve. All this guy did was say "hey i've seen guys make over 1000whp on this turbo, i'll slap it on there, put a small exhaust behind it and call it done." I've never seen a decently built engine that has it's full boost, torque peak, and hp epak all at the same rpm.

Edit: Jeremy clarkson of top gear mentioned that the problem with a diesel engine is that all the poewr comes on all at once and then it's gone, thats exactly what this guys engine does. He has over 500 hp come at u inside of 1000rpms and then goes away just as quickly.

I FOUND ONE

http://www.is300.net/forums/showthread.php?p=3046854

Notice the torque, this IS300 makes power sooner, has a flat torque curve, and still makes more peak HP @ the wheels

Here's another, not as much peak hp, but again, look at the torque
http://www.supraforums.com/forum/sho...hreadid=248105
from 5200-6200 the torque is FLAT. and them smoothly drops off. Thats a better turbo engine.

Here's one more
http://www.supraforums.com/forum/sho...ghlight=smiley
This is a 1jz torque curve. 500cc's less than the 2jz and a better flowing head. 830whp and a nice torque from 5700-7000rpms

hey river got any pics?

Im totally with you guys. Just doesnt make sense at all. Lets see some pics and a dyno sheet and we will all shut up.
