300whp S70 T5 Manual

[JCviggen]

who?

Basically if you close the rod on the WG you FORCE the manifold pressure to rise but you also force more air though the turbine = more boost.

You can weld the gate shut, but partial throttle surging would be a sob.

and run an external ? welding the gate shut wouldn't be the brightest idea, unless you were joking, then :lol:

Glad to see you didn't take me seriously man. :)

<_< sometimes i wonder that you guys have the same hp at the wheel that we have at the crank with the same mods we have in Europe...

who needs to expell those gasses anyways... the more you expell the less you make!!!

I think he was kidding heh

like me.

[zazzn]

zazzn how 'bout a better wastegate in general?

More pain then it's worth to put an external wg and weld up the stock internal....

might as well just get a new turbo if you gonna spend all tha tmoney to modify all that crap.

Actually, if you read zazzn's a bit more critically, he is actually discrediting EBC's to a point, and instead suggesting that our factory wastegate design/size is the problem.

Well EBC's are great the it's two fold to make this work, you have to stop the surging by allowing the wg to open via ebc / MBC and you have to hold the boost via not allowing the wg to open.

He makes it sound like extra manifold pressure is something innocent. It isnt. It reduces power, puts more stress on the rods and lowers the "knock-limit". Especially because this is already an issue with our cars stock exhaust manifolds and tiny turbines. Aside from that if a 16T were to hold 20 psi at 6000rpm on a 2.3L engine you'd be so far off the compressor map its not funny.

294 whp on a 16T would be a nice example of a dyno that aims to please.

JCviggen, no one said it's good, but i've heard the same story you tell time and time again form people over and over. Many people love to regurgatate this story over and over but never want to test on their own car. If I didn't adjust my rod I wouldn' tmake more then 13 PSI to redline. Currently i make 15 to redline and spike 20 because I don't have a EBC or a MBC for that fact.. I just simply have the WG line pulled right off. I've been driving my car like this for 1 year.... Before, you say it... Yes it's been to the dyno and it's 10:1 on the dyno so yes there is plenty of fuel... Exactly like I preeched before... You'll hit fuel cut before you run out of fuel... (I did when I hit 22 psi one day fooling with the rod)

by the way just because it's off the compressor map doesn't mean it's not making power, simply JUST less power, and not all comrpessor maps are valid. Take for example the Garrett GT35R people are making 600AWHP but yet they claim it can barely do 500 crank.

I'm not saying anyone has to follow what I have done, no one has to listen. All I know is, many people would rather you buy their expensive snake oil when you coudl simply achieve the same setup if you had a little know how.

Thanks. Gives a clear view of your level of tuning and understanding.. :rolleyes:

But, 600AWHP is not ALL turbo. There is an engine on there too. For example, my 18T makes roughly 300WHP on my car @ 20 PSI. But if you put a turbo kit consisting of my 18T on a Ferrari Enzo, It would be over 600WHP even on 5 PSI.

I recently boosted 22 PSI => 20 PSI from MBC by stretching spring + WG rod shortened 3 times.

I bent a rod and 5 hydraulic lifters AS SOON as I did this. Not cool. BUT, my timing was also advanced and it could have helped bend them.

Be safe guys. Instead of getting another 20 (twenty) WHP on your car, thus bending a rod and lifters, just lighten your car by 200 Pounds and get the same results.

Recap: 20 PSI is fine, but 22 is the danger zone.

[Zulu]

Dunno, I run open WG all day 23lbs.....just don't go WOT in 5th @ 2000rpm lol.

[550]

hehe, I ran closed wastegate on my old 13g... but thats different. haha It had 150k miles on it... what a good little turbo :)

that engine would out flow the turbo at just 5 psi after 3000 rpm, do some compressor map calculating

any dyno graphs on 18T at 20 psi so I can compare to the other 18T done by Marco?

[TurboSam]

I wonder how long 16T with 20 psi hold will work... 20 psi to 6500 rpm ? in your dreams The turbo specialist here in Switzerland says 300 hp with an 16T at the crank !. It's always a question how long things have to work.

Thanks. Gives a clear view of your level of tuning and understanding..

Your sad shot to at putting me down is patetic, NOT only have you NOT provided ANY good infomation to the thread but you bash me directly. You probably haven't even hit the same level of performance that my volvo is doing let alone make 523 WHP. YES my 523WHP supra was all created BY MY 2 HANDS, from tuning, to part select, to installation.

Grow up, and post something constructive, I SPEAK FORM EXPERIANCE. You are a LARGE reason why no one want's to even bother posting to help.

Lextildeath, i'm sure it had nothing to do with the boost being at 22 PSI. I'm sure you either detonated (especially if you where running pump gas) or you went too lean. I have a feeling you detonated because if you go too lean on good fuel usual you just melt something. In this case you took out the a rod which in tern took out your head which causes me to believe you detonated.

Anytime you are doing ANY boost modifications you should have the proper tools to know if you are going to cause damage. A wideband/EGT is highly recommended, however, a dyno session can be just as useful. Every car responds differently. 21 PSI on my car may not work the same as 21 on your car. All i'm saying is blame the tune now the motor.

Pathetic, from, and experience.

Regardless, pull some timing logs of your S70's current setup, and let's see where all this EXPERIANCE has taken you.

BTW... news flash, hate to break it to ya... but making 523 WHP on a 1JZ is like properly installing a chip/mbc/turbo/exhaust on any 850 T5. Congrats big boy. Someone break out the fking party hats.

[JHEIII874T5M]

Also, with the wastegate line unplugged, your turbo should be seeing much, much more than the reported boost levels. Check your throttle body hose for a tear. If it's got one, might want to put a Samco turbo hose kit on there.
