Twin charged, Innovate on top and AVO on bottom

[RedLeader]

A twincharge system on this car would be great, but personally, I'd use a roots type s/c instead of a twin screw. There's no internal compression as it just compresses air against the intake manifold. then pair that with a fairly enormous turbo, one that would probably never see enough flow from the motor in its stock form. Use the s/c for the low end and to increase flow so the turbo can spool. Fueling upgrades would be required unless the stock system can handle the amount of air flow generated. The hardest part would be getting the motor to handle the increase in air pressure. at that point I think you'd have to do low comp pistons as you'd be shooting for a 25-35psi output from the turbo, after the intercooler and going through the S/C.

If anything, maybe do a "twin turbo" sequential setup using an electric turbo feeding something like a gt35.

Use the electric turbo to provide boost from 2k-5k and the gt35 for an amazing kick the ass from 5k-redline. I wonder who would want to tune something like that? Wouldn't be much different using a hit of nitrous to spool a big snail. That's been done for drag cars.

Guys. As I'm sure Nix may already know I am currently neck deep in my twin charged twin intercooled system. The turbo I am using (made 354rwkw) is a Gtx3076r modified by blouche and got me the highest hp 86 in Australia title. I am running a PERRIN barrel cooler between the turbo and the sc as I already have cooled water from the sprintex intercooler system. The supercharger will be set at a stable 9psi and will be fed another 14psi from the turbo compounding the boost. This is on a fully built Fa20 with 10.1:1 comp. It should make a little over 400rwkw and minimal lag.

That's supposed to say PWR barrel cooler not Perrin obviously lol....

That is awesome! Do you have any pictures or videos? How's the off / on throttle response? Does it feel torque monster or a boost bomb?

[@Art_Mighty]

This would be the mother of all FA20 builds but with one of these and a serious fuel system I would say go for it!



Seriously people on this forum here need to lighten up. If you have the $20-$30k to put into such a monster build and you made it work we would worship you...

This has been happening on Mustang Cobras for a couple years now. Cool idea. I know the cobras are putting down good numbers with it. Interested in seeing numbers on an 86

This is the turbo setup I built. 473.8hp. Currently installing the sc as we speak.

why twin charge you say? because racecar. or because this --->[ame="http://www.youtube.com/watch?v=HmscSzFurwg"]The World's Fastest Lotus? - /TUNED - YouTube[/ame]

I'm no expect on fluid dynamics, though, but i'm sure someone can chime in to talk about the friction aspect of it.

You don't get it. The supercharger flows a specific amount of air per revolution, yes, but the limit there is the amount of air available to the supercharger at the induction point. If you push more air into the supercharger's inlet, you are going to be moving more air at the outlet also.

A roots unit would be better for compound charging, but the twin screw isn't as much of a limitation as you're implying.

To the OP: You need a bigger turbo for a twin charged setup. A 300hp blower with a 300hp turbo is going to result in a 300hp max. Your example would result in an AVO turbo car that makes less power than other AVO cars. The turbo is the limiting factor, airflow wise, and the supercharger is going to be sucking up horsepower that other AVO cars aren't losing.

Yeah, I ignored his reply as he had no idea what he was on about.

I await your technical explanation with baited breath.

Highly technical explanation incoming.










































More air in = more air out.

Lol, he missed out density as well....
It isn't as if the 2 compressors are trying compress gases into liquid...
