wow,
please describe to us the kind of blowers top fuel dragsters use and how they are "actually low man on the proverbial totem pole when it comes to power per pound of boost"
and your last article just supports what BP said and why the GTR is a show car. YOu use roots blowers with turbos, not centrifugal type chargers which are just belt driven turbos..

so
I showed the GTRs example to prove Centrifugals can do the job. (Maybe not as well but it gets it done).
Top Fuel Dragsters....really.
those blowers have more cubic inches that our freggin pretty pink girlie VQ35s...

^ just like a radiator or intercooler or a simple fan at home. the designs has a max CFM or flow rate it can handle. Thats why BP used the bigger M93 over the M90 due to the amount of volume the blower can physically digest.
if you add the turbo before the SC you do not get the compound interest affect. The SC is stuck having to pull its air vs being pushed. They do work together in the SC after turbo, dont get me wrong, but if you can combine them SC after turbo and keep the inlet temps down that would be a more effecient option of using the two.

variable geometry turbines are where its at...
Their pontiac G8 kit has boost at 1100 rpm and 10 psi by 2000 rpm.
Other VGT and VNT turbos in the diesel market are allowing for huge torque numbers. This technology will continue to develop and there will be no turbo lag.

$2500 each:

Not that big either, only 540cfm.

I didn't say it was cheap. Obviously anyone interested in twin charging is not looking for cost effective. Aerochargers are small, but I was only showing the technology, and it definitely works. Porsche uses it on the 911 turbo which makes full boost by 1500rpm.

My friend travis has an Eaton 90 on his older v6 cougar. He's 14psi by 2200 rpms.

Obviously we are not talking about positive displacement superchargers. They all make boost at low rpm, and then puke and die up top. A VGT or VNT turbo will make boost at a low usable rpm and then not puke and die up top so they can make some serious power.

Okay first off I know this thread is old. Actually the last post was like 4 years ago. But I was on driver and its on there for a compound charger thread. I have an idea... So I have an upgraded turbonetics kit, and a fully built motor to match it. My buddy's z has a Stillen supercharger... While looking at it before he installed it I got to thinking could I drop that supercharger on then type it down to my turbo kit... In my mind this plays out for a huge hp gain... I know there will be a ton of work needed to support it all, but any advice or help would be good. Is my though completely stupid and flawed or could it pan out?

Well, if I go and buy the stillen supercharger, I would swap over to a Garrett turbo. I may be swapping to a Garrett no matter what. I didn't know someone had done it. I googled it and have been around in the g35 game for a long time but just recently came over to the 350z game because everyone on the g side is going to form not really power. Plus it's getting dead now.

If you plan on doing this, make sure to get a properly sized turbo....with a T4 turbine housings...big A/R as well. All top mounts come with the small T3 housings, so that (T3) flange would have to be cut, and a T4 flanges would have to be welded on.
Even built Honda guys go with a T4
