My car gets into boost at a lil over 2k rpms...that doesn't seem like very long to wait...but that's just me.

1-3 full boost at 2800, 4-5 full boost at 2600 for me

looks like im gonna break 28mpg this tank.. we'll see

i dont see it making over 200whp.... ----, a jackson racing super miata (i know gay roots) makes what 120hp at the wheel?

I was so hoping this was going to be a cool thread from someone that knows something.

I have a millenia supercharger sitting in the garage that i've never messed with in a long time, lol. I have never found solid information as to what size the blower is. I'm guessing its 1L or smaller. running two might be pretty interesting. cramming ~2L of air per rev even at 1:1 ratio is going to make insane manifold pressure on a 1.8L. I hope you run a nice exhaust system to help it breath, otherwise I see instant carnage in your near future. i'm not sure how well the BP will take to high cylinder pressures at low rpm's? either way cool project and i'm interested to see how it turns out.

It's a 1 liter displacement twin screw manufactured by IHI.

Exhaust will be a custom header with 2" primaries to a 3" collector and 3" to the rear. It should make 200 whp with 2 SC's and a 100 shot direct port.

When I say I don't like waiting for boost...

I had a 300 zx turbo. It took till 3500 and then bam, full boost. Nothing below 3500. I've rode in other cars that were turbo and I know boost onset is low, but full boost is not. Yeah you might make a pound of boost at 2K. But a good size turbo to support 300+ whp efficiently will have lag. Most miata guys running t3/t4's are waiting till 4-4.5K for full boost. It would be fast on a track, but I want power down low where normal people operate there vehicles in daily driving. I know this is HMT and I'm not bashing turbo's and all that ----. Just doing something different HMT style. Boost is better than no boost.

take away the 100shot...

and youre back to 100hp

but power below boost is not needed
i mean if you are driving fast then you will be spinning the engine fast enought for boost
and when your driving normally you are out of boost and thus not making more power than needed and as we all know the more power you make the more fuel you need so you can take a small engine that gets 30-35mpg and turbo it and double the hp and as long as you are out of boost get damn near the same fuel millage and then when you want double the hp just drop a gear and hold on

and i think running the superchargers in a push pull configuration sounds like the dumbest thing i have heard on hmt (and i have said some stupid ----,lol)
i mean if you are sucking the exhaust out then you are going to be making negative pressure (vacc) on the oulet of the engine and if there is any valve overlap you will get allot of blowby witch will make it a bitch to tune and shoot raw fuel out the exhaust(and fuel is expensive)

as for running 28psi and only making 300whp?
what the ----? (on top of that you even said the supercharger is enefficient at 22psi and above)
i mean a t3/t4 would make 300whp at like 15-18psi (depending on a/r ofcourse)
maby even less with a really good tune
as for cheeper? i doubt that i mean you could have built a dead reliable 300whp turbo setup for under $1000
and it is more reliable,puts less strain on the engine, and is not gay


have you even thought of howmuch parasitic loss you are going to have with spinning those 2 superchargers that fast?
i would guess it would be somewhere arround 18-40hp


like it has been said before prove us wrong about your idea but i honostly think you should really think long and hard about what you are doing and take a look at it in a different light
because it's not even innovative it's just semi retardid sounding

in for the updates. i dont care if its worth it or not, i like seeing things that are different

+1 I want to see this thing work!!!
