Im ready for ROUND 2..., Ninja turtle 2 progress springs/tires Options

[easternpiro1]

Hey guys, thought i would post what ive been up to the past couple of days. Been having some crazy outside issues (dont worry guys in the f/s feeler i didnt forget u)
i made it naked in record time with just a few things left in there.

so i guess we all know whats next...right?













BABY OIL GREASIN HER UP FTW! LOL!



next up...





its in georgia now, and tweak will be doing the wiring and oversight of the swap. lets pray the motor isnt ruined!

from what ive read, every 90* bend is the equivlent of 3' of straight pipe.
when that kinda info comes from guys like rickyb and the like, i would trust them.


i havent built a full exhaust yet, and i havent dynoed the celica with 3" over, then under to see the diffrence, so i cant really say for sure, but to me it seems the whole point is to get the exahaust out in as straight and short a path as possible for best results with a performance exhaust.
not that i dont "like" the idea of going over the axle, i think it looks pretty cool actually, just dont see the point when your building this kind of car.

as for the wastegate placement, i really dont get what you mean by "technically all four runners are in the same chamber".

the wastegate is placed directly off of runner #3, before the 4 runners converge, as shown in this pic:



and this one:



its VERY much like this cast manifold that turbonetics made back in the day, in that the wastegate comes off of a single runner:

the results of using it like that ends up like this post on mr2oc from a guy who used one:
http://www.mr2oc.com/showthread.php?t=3077...netics+manifold

in a nutshell he would make 26psi...with a 7, then a 15psi spring.
in an effort to see if he could get ANY boost control with that manifold at all, ran it open, with no wastegate at all, basicly creating a big leak, before the turbine, and still had terrible creep issues.

not trying to bust on ya tweek, just pointing somthing out that i noticed, and i figured the OP might have overlooked, before he gets the car and wonders why he cant control boost at all.

as for the wastegate placement, i really dont get what you mean by "technically all four runners are in the same chamber".

The manifold that you gave a link to is a twin entry. Two of the runners converge and then go to the turbine, and the other two runners converge and go to the turbine. That means that there's absolutely no chance that any exhaust gas from two full runners can escape.

The manifold that SCC built is a single-entry, so all four runners converge before the turbo. This means that technically all four runners could vent gas through the wastegate. Though the wastegate is higher up on runner #3, all of the runners still have access to it through the third runner. Remember pressure is what turns the turbine, and that pressure, which builds up in the manifold, is released by the wastegate. Not defending the design, I would personally have built a whole new manifold from scratch, I'm just explaining what I meant by the exhaust gas in the four runners all being in the same physical cavity.

But, I have a feeling it will be fine. Like Lagos said, take it out, and if it creeps, you'll know why
