I specifically chose my internet source because the author apparently does not know the difference between "it's" and "its", therefore everybody should believe it, lol.

The problem with bleeding off P2 is that the compressor has already gone through all the work of compressing the gas. This work takes a lot of horsepower from the drive system and heats the air much more than necessary. Therefore, using a simple 2:1 bleed ratio as an example, you would end up with only 10 psi worth of manifold pressure at the cost of 20 psi worth of compression heat and drive system loss... not good. This is why turbochargers are controlled with wastegates on the exhaust turbine end rather than on the compressor end.

In order to achieve what you are looking for, you would need something like the Antonov 2-speed supercharger:

hahaha if i could afford the s/c id take it off ur hands nao for my na. but sadly i dont atm. hopefully i might get the money but well see ^^

 

Evil: hell yes, those 2-speeds are awesome!

epic: yea, like i said i am currently talking to a guy and there are two others behind him! the first guy is serious and has already given me an offer (a bit under what im looking to get), but i havent really talked to the other 2 guys so i dunno how serious they are.

 

Often times I thought of just throwing my car back together in the quickest and shittiest most ghetto way possible just so people would take me seriously. Then it hits me like a ton of bricks - oh wait - I have a MUCH higher standard than most of those little kiddies and honestly, if they don't know knowledge and good advice, let them learn the hard way


I understand what you're saying, however, I would think that the drivetrain losses and the additional heat wouldn't be that great. Here's my logic - if the compressor is spinning enough to create say 20PSI and the pop-off valve is set to 10PSI, yes there will be additional heat generated and additional losses incured. However, at the end of the day it it still 10PSI and *shouldn't* be the same losses and heat generated at 20PSI. My thought is that while the SC is spinning for 20 PSI, there isn't 20PSI of manifold pressure.

I understand exactely what you're saying with the wastegates though and how they work by bypassing the restriction and the excess boost/heat created on the compressor side and more importantly I understand how they *could* be made to be more effeicent.

 

I think you know what I'm gonna say... (hint- see sig)

 

haha, long time no speak introvert! hows your s/c going? got it to the dyno yet??? also, any headway on the intercooler problem or did you decided to go AI like me?? ....well like i had decided to...

 

I know you've already thrown your FS ad up, but I think a 10-12 psi supercharged rotary with Meth injection on High compression N/A rotors, ported 6-port engine would be BADASS! I mean, for the moment, all it will cost you is the rebuild (obviously), some form of engine management and some AI, all things that will carry you over for if/when you decide to turbo it. Don't assume that the higher compression rotors don't fair well with boost, look at Aaron's turbo High-comp. motor, it's making some good power on those suckers! Just some food for thought, it will likely cost you the same to sell the kit, buy the turbo and all the other goodies you will need anyways, but the turbo will have more capability and room for more power. This is all depending on if you sell your supercharger kit easily/for what you want.

 

very true. at first i believed it would be very easy to sell this setup. i have went threw two buyers already tho who are not willing to meet my asking price. i think now i will either have to take a hit on the price or just wait it out which sucks cuz i got the motor back about a week ago and have already started buying parts for the turbo build... hey since you think its so badass why dont you buy it?? shoot me a pm if your interested!

 

sorry bud, already got a turbo engine in the works, I'm just saying it's nice to see something that's not so everyday.

 

haha, yea true. like i said tho, it was really fun while t lasted, just looking for more power
