Twin charge or ban.


Srsly, I bet someone here has extra IC piping to donate meow!

How about in the name of MURICA!

Yep. I just think it would be interesting to have a very clear datapoint for the 'a SC car will be faster than the equivalent turbo car because throttle response' people (not that they will let facts get in their way anyway).

 

lol honestly I think that argument might have some merit simply because the n00bs arguing it don't have enough experience to handle a turbo setup on track and spin out or crash or something.

But yeah I intend to datalog all this mumbo jumbo and post it up

 

I'm pretty sure it's more complicated than you guys are making out. You need some way of bypassing the charger at higher rpms' i.e. past peak torque, or t just becomes an epic restriction.

It's not as simple as plumbing the turbo into the charger.

 

actually, its as simple as getting an external wastegate to work as a boost controlled valve

A twin screw super charger takes a fixed volume and gulps it into the engine. When the turbo pressurizes the air that air becomes more dense.. so now the SC takes a volume of pressurized air and gulps it into the engine.

 

This would be an epic build, not going to lie. I'd attempt it myself if I had a twin screw just lying around. Ever since I saw that video of the Lotus Exige that was twin charged

 

Two things I found on google when searching for "twincharged miata"

 

Exactly!

Stop whining and do it. I am not asking you to fully optimize the system.

 

Happy to be corrected, Done a bit of reading and it seems you can do either, with or without a bypass. Mind you look at the 2nd pic, look at the layout, TC>SC>IC

That'll be great fun to route. Read impossible with a FFS supercharger setup.

I've considered the setup myself seeing as I have a coldside supercharger, but I doubt I could afford the cost of a built engine.

Heh, in for 40psi Vlad?

 

if we all twin charge what will this site be named?

 

When I had my FFS I wondered a long time doing twincharger setup. Piping is hardest part and it’s not even that hard. Just one 180 turn before throttle body and then long pipe under the FFS intake. That’s all, rest is normal turbo IC routing. I found out that there’s no harm feeding positive pressure to the SC and you can always modify wastegate actuator to the MP62 bypass lever so that when turbo starts feeding, large part of the air bypass the SC rotors.

So do it !

lol

 

Well, I don't know if I would be willing to be a "guinea pig" either for such a project, but I disagree about it being overcomplicated retardation. Given that you already have (or will have shortly) all the parts I have to say I wish you would reconsider. I mean, You have the parts, you have the knowledge, and damnit, people like you.

I'll still respect you if you stick to your guns, but I will be disappointed not to see that epic build thread.

 

I sure with the 30 or so turbo kits he has at his disposal, he could cobble together something...

 

I wonder if you can beat Faes 350hp dyno at 35 psi

 

It's definitely overcomplicated retardation. The turbo he eventually wants will make MORE LOWEND TORQUE than a roots blower.

 

LOL I'm sticking to my guns, gayz.

I'll be done with the thupercharger by December and be installing the turbo goodies, so you are all more than welcome to buy it and run 100psi of compounded boost glory, faefae style

Anyways, some minor updates:

Scott contacted the developer(s) of MS and was informed that nitrous IN can't be used as an input for AC like he thought. or something to that effect. So it was set up wrong. So yesterday my friend came over and re-soldered a few pins on the DB37 like a boss and I sent my most current msq to Scott to re-do the software portion of it.

I am REALLY REALLY REALLY REALLY REALLY REALLY hoping that fixes the last of my issues and I can finally finish tuning this bad boy.

So far it feels just like stock, but with about 40 or so (butty dyno estimate) bump everywhere.

I fabricated a 3" midpipe and bolted it to the car. I think its overwhelming the stock muffler though cause from about 2k-3k it rattles like crazy. Pisses me off and sounds like some old ratty honda civic or something. Will have to figure out what I'm gonna do about that. Don't wanna go full exhaust yet because I want to keep it quiet. I dunno
