Is that an app to measure 60-130mph time?

The p3 gauge from auto couture does that.

We will discuss strictly the S65. With lets just say 100 octane race fuel, and lets just say 27* timing, how much volume of air does it require to make 700hp# 8k rpms, and lets just ask how much MASS air is required to make 700hp@ 8k rpms

we know that 8psi, 27* and 100 octane will be roughly 600hp @8k rpms from a 1100cfm centri s/c..

so educate me on how 11psi @8krpms will get 700hp on 100octane..

how much AIR are those turbos required to push?

See what im getting at yet? It doesnt matter how much smaller the turbos are, because there are 2 of them, but combined they still need to flow the air, whether you are calculating it by MAF or CFM, it still needs the same air, more even..

SOOOOOO..

What are you arguing here? I know I never said anything about the turbos not being more efficient than the supercharger so you really lost me with this one. Again since you haven't typed more than a sentence in any of your responses with out it being off on a tangent I don't even know what you attempting to prove here? I recall saying you can't compare what happens on a blower to a turbo setup a few post back as if they are equal. My last response spoke on the number of reason why you can't compare the two setups of saying why supercharged cars have failed vs the turbo using a boost as a measurement of why is a mistake. SOOOO you attempting to dumb down something that was never being argued is quite funny. SO why do we start with what you are trying to debate and we will go from there.

Both of you take that shit to private message
enough!

You claimed that 11psi from the TT wasnt the same as 11psi from a s/c because it was at 4k instead of 8k rpms, and inherently safer. I have thoroughly explained how that is just plain wrong.

[Fatandre]

So from looking at this car and the other supercharger kits out there which one would you say is better?
I cant decide what to go with on my car.

[Weyne Masters]

If you have enough money like 15K-18K
Go to Turbo!

[SVH]

More like $18,500 plus install costs, plus a lot of patience....

[L4ces]

On a different note, I was hopping to hear and see some footage of this creation and still nothing.

Ping ping Luc! Didn't you have the GoPro?

How's your build coming along?

Well let back up as I actually never said anything about 4k rpm turbo stress vs 8k sc tress as a comparison you may want to go back and read my comments. As I Said "let me know when you start seeing people with sc cars start races from 4100rpm" That is the only place I mentioned RPM in the argument.

UBER MAD stated "11 psi at 3500 rpm's affects the engine completely differently than 11 psi at 8500 rpm's. There is significantly more pressure and load on the engine internals. You can't just look at boost numbers and say " Oh well there are Supercharged S65's with 11 psi of boost so it will be ok". It's not apples to apples and people don't understand that from an engineering perspective. A piston will crack or a connecting rod will bend/brake from the extremely high cylinder pressures at lower rpms."


So from the start of this argument you are mixing two people up to begin with.


NEXT you can't not compare a TT setup to a SC setup. espically a water to air vs air to air setup.

I don't think you realize what efficiency is, which is what I was trying to help you understand with the comparison of power made by a smaller turbo at 11 psi vs a larger turbo at 11 psi. Twin 3076s will flow more air with less heat at 11 psi then a centrifugal blower that s being spun to 90k revolutions. You can not compare the two and say oh this car with a sc blew up at 9 psi on race gas so that twin turbo car at 11 psi is going to blow up on 11 psi with e85. Which was my point to begin with. Turbos are more efficient then centrifugal blowers. You have to account for parasitic lost and the strain put on the motor just to run the supercharger, where as the turbo is using what would have been wasted energy to make power.

Have some engine issues to clean up. Hopefully soon.

No man, I got a new GoPro 5 sessions specifically to take to NoFlyZone, thought I had it charged and when I went to use it the day of, it died on me 5 minutes in. I had to take it back and get a new one because it wasn't charging right. Car is almost done getting tuned with the Syvecs now so when I get it back, I'm going to go play around in Mexico with a few cars so everyone can see how it runs.

In terms of power delivery it blows it away. There is no comparison, especially running e85. In terms of bang for your buck, with how inexpensive you can get supercharged kits for now the supercharged route is the way to go.

Whatever happened here?

ended up bending 2 rods, motor is being built

[Weyne Masters]

Tô much torque For Stock engine!

[squartus]

So an engine rebuild is prob going to be required for twin turbo builds, so deft raises the cost.

[LangRacingDevelopment]

Those rods are pretty weak, that should be expected.

Were rods ever suggested or did it ever come up as a possible weak point?

I remember asking early on in the build if he was planning on addressing the rods and he responded something to the effect of wanting to find the breaking point of the stock rods. I'm 99% sure he knew rods would give

No motor build is needed if you wanna push 11lbs with e85. I could have ran 7lbs on 91 and been just fine.

Yea I knew I was definitely pushing the limits so it was only a matter of time. Doing titanium rods now, dropping compression to 10:1. Billet crank with cams and valve Springs. Going to push redline to 10m.
