Either way Srce, this is a TON of money for minimal gain and street usage, IMO.

How in the HELL is that minimal? His wastegate would barely open in 1st Gear! |

umm, yeah you would be more power, not much more power would be like twin GT25s. Piston guys see well over 400-450 hp on this turbo SINGLE. Two of them, although a bit lower output on a rotary is still capable of like 700hp. i really hope that you've considered what **** is going to break with that much power. Its not like you can just build it once and not have to keep putting money into it.
So, I missed needing one more wastegate, how much would a custom twin manifold cost? Does anyone know, and I don't plan on drag racing the car. This thing will get most pulls on the highway and road course. |

Hmm, I was thinking more like 5K. Turbo's are $2,500, a big ass IC core at about 700 including piping, and the rest would suffice for a manifold, dp, fuel, and wastegate? No?
Plus, why would I need a new drivetrain every week LOL? It's not like I'll be making more power then any of the single turbo guys. yeah you're gunna need way more than 5k to get this goin i know this first hand cuz im goin through this whole upgrade ****, and im getting great prices on everything i get, and sean is helping me out a lot with the labor and with all parts already fabricated, im spending more than twice of your projected amount. |
I hear ya Martin. This is a long way from now, I'm hoping to jump into a car by Rotorfest, go stand alone right away, rims, and basic bolt-ons and reliability mods. Hoping to be GT30/37ed over winter.

wahwahwah...bunch of babies you guys are. Ask IGY how much all that cost him...wahwahwah
|
well as long as you're prepared to spend on your wet dream..... hehe j/k
oh yeah.... dont forget about your engine, cant slap that on a stock engine, you wont see boost til tomorrow morning....... hmmm slap on another 5k for ito to build you something that will spool that **** up and handle that much power |

You say you like to plan things out before you do them which is good. But what are your goals for this car? |
My goals? Hmm, road racing, occasional drag run, and highway driving. BTW, just to make this a bit more impossible, this car will be my daily driver. https://www.nopistons.com/forums/pub...1047683785.gif

hehehe, ill try out 500hp at the wheels as a daily driver, and tell you all about it before you go doin this setup.... hehe
|
you cant really use that kinda power roadracing, unless you're a really good driver and even then.....
that being said |
i believe those were gt3035's but i'm not sure. the guy really hasnt gotten the car running yet either
|
is that guy seriously putting those turbos in that engine bay?

you know with IGY's setup he was boosting 8 psi...let me say it again...<span style='font-size:21pt;line-height:100%'>8 PSI</span> and was making over 400 rwhp.

You can make 400HP on a single for a lot cheaper than his proposed twin setup. That was my point. https://www.nopistons.com/forums/pub..._DIR#>/sad.png

But Scre isn't going for "only" 400 rwhp or the "cheap" route. He's doing it to be different and make lots of HP...plus bragging rights of having a very unique setup.

Hey if he wants it, more power to him. https://www.nopistons.com/forums/pub...IR#>/smile.png |
srce,
have you talked to Howard Coleman about his setup? His name may have been mentioned early on in this thread, but what was stated was not up to date. He is trying out a twin t-04s setup right now and is just now breaking in the motor. He told me that he saw 5 psi of boost however by 2100 rpm. He has been working with majestic turbo, and I can't wait till his engine is broken in and then tuned so we can see what he gets out of that setup. Bob |

Explain to me How it's UNRELIABLE? What exactly makes it UNRELIABLE? Parts will break REGARDLESS of how many turbos you strap to the engine....500+ hp tends to do that. If anything, the engine will be MORE reliable. Remember I said IGY had 400~ hp at 8 psi...most single T-04S cars were making 400~ hp at 14 psi....so He does NOT have to run more boost because he has more air flow.
The amount of boost doesn't really have much to do with reliablity in my mind, it all comes to how much air you're flowing, so you can't really base reliability on the amount of boost someone is running... For instance...a Y2K running 6psi is going to flow a lot more air than a T28 at 6psi. So, you could make the observation that the Y2K will cause the motor to be more unreliable simply because of the amount of air it is supplying to the motor. Look, I'm no expert, it's not a secret. I'm just trying to make common sense out of "reliability" and "2 big singles" describing the same motor, let alone being in the same sentence. |

Your confusing yourself too much young Padawan. Yes airflow is what makes HP. However, how many engine failures do you know are from LOW boost? With high boost engine's(19 psi+) tuning becomes CRITICAL. Low boost...they'll run forever. So he'll have the best of both worlds...Low boost and high air flow. Downside is COST and COMPLEXITY. https://www.nopistons.com/forums/pub...IR#>/smile.png
See conceptually to me that doesn't make sense. Wouldn't it have more to do with the sheer volume of air you are forcing into the engine? |

Why would an engine blow simply because someone was running 18psi on something like a t-28, when that same volume of air could be made from a T-66 at 8psi? I don't understand the difference...why would the motor blow if it is receiving the same amount of air, but with a more efficient turbo? |
COMPRESSION RATIO.

On that same thought though i'm probably wrong but wouldn't the whole complexity thing in turn make it less reliable? I suppose it would be different if you did your own twin turbo setup, but mazda kinda ruined it for me with the their version of the twin turbo system on 3rd gens.

theoretically more power = higher combustion pressure, so a 400hp 13b should have a certain amount of combustion pressure, we'll call it bo. when you compress air it gets hotter; hotter = more prone to detonation. we'll call that luke.
and we'll call airflow daisy duke. so the less luke you have the more daisy duke you can have for the same bo! or airflow isnt the reliabilty problem its heat, or heat induced detonation detonation is somewhere along the lines of 10x more pressure (plus a shockwave) than normal combustion, this is why it does so much damage |
nice analogy
|
I think what Mikeypoo is trying to say is that higher compression(more boost) will raise the intake temperature higher and thus increase the chances of detonation. When a turbo is in it's effeciency range(and below) the air it blows into the engine will be of a lower temperature than a high boost turbo.
Did I get Daisy, Sally, Jessie, Bo and Luke right? https://www.nopistons.com/forums/pub...1047683561.gif |
