Is there any place I can buy a kit for my 535IS? Any easy way to peice together one?

Kit, TCD, read this board a bit.

I recommend the Turbonator! A lot cheaper and easier to install

Oh my,
you must have saw that thread over at the BF.C forum! Did you see my post there

RussC

naw... I can only haunt one forum at a time and I chose you guys (GROUP HUG!!!)

Ok,
Heres what I posted:

While I don't think that the turbonator works, can the theory have merit, if implemented properly.

The key I was thinking of was the water fliud in the two bottles. Spinning the water(like a drain in a tub) will make the water flow from one 2l soda jug to the other much faster than if not.

Well, fluid dynamics and gas have the same properties? So, if you put a turbonator in each inlet tract for each inlet valve, then the the spinning air can flow in cleaner into the combustion chamber????????????????????
The thinking is that like the spinning water from on jug into the other, this equalize's the pressure from the combustion chamber to the intake plenum, reducing flow restriction.
Can that theory "hold water"?....

Strike that, my theory is bogus. The water jug system works because your trying t displace air form one jug to the other. Thats why it works. The intake system is different. The vacum uses pressure differential to do the same thing, so no pressure equalization is necassary. The only thing that can work is if the swirling air has less flow resistance through the port/valve by spinning!

Or is this thought whack......

RussC

Yea, the tornado works for the soda bottles because it's a closed system and you need to have simultaneous flow in opposite directions through a restrictor. The intake system of an internal combustion engine is a little different.

Some engine builders have been using "swirl cuts" on valves for a while though, so there might be some merit to it. I have my doubts.

YEAH!!! Im going to go NOT buy a turbonator!

Then im also going to NOT buy a cheap-o eectric supercharger!

Are the TCD kits worth the 5g's it costs?

What kind of power could I expect from the kit bolted on the stock motor?

Speaking as someone who is doing it piece by piece -- yes. Unless you have time to track down parts, deal with worn out and broken parts, fabricate parts, and figure out the best combo of plumbing and components to deliver the expected performance with reliability, you'll be time and money ahead sending a check to TCD. Actually that's wrong. Even if you DO have time to do all that shit, you'll still be better off.

Why have I not done so? That's a damn good question.

I believe the average install nets well over 300 wheel HP. Stock US 3.5 is maybe 160 at the wheels. That's some serious additional grunt.

Great call, power will be 75-100% increase.

160whp is being generouse for these 18 year old engines. They usally dyno in the 145-160whp range. They only get 160whp when there new.

162 whp at 220k miles naturally aspirated, thankyouverymuch! Blue line is stock NA. Red lines are the latest turbo run.

Currently putting down 250 rwhp and 303 rwtq at 10psi non-intercooled. I have at least another 10 rwhp to gain if I can get my fueling issues corrected above 5k rpm.

I think electic motors have a future in turbocharged cars:

http://www.freshpatents.com/Electric-mo ... 216458.php

What I would like to see is an air reservoir filled through the waste energy used to stop the car. Instead of the energy going off as heat and brake wear, it could be used to refill an air tank for those times we need an extra little "boost". An instant 1, 2 or 3 bar at any RPM, at any speed...

Not only would the boost be instant (no turbo lag), the charge air would be nice and cold (dense) because expansion is a cooling process.

Optimally I think it would be best to have supplemental injectors functioning like a pressure fed spray guns blowing fuel into the ports to atomize the fuel/air mixture.

YMMV...

Imagine the size of the tank needed to hold enough air to pressurize the intake to even 1 bar for just a few seconds.

Not practical at all, but a cool idea.

I was only going to peice a kit together if the TCD kit wasnt worth the 5g price tag. At 75%+ gains it is definately worth it. I am going to get a motor for this projecto though.

My sense of it is scuba tanks (3x80 cubic feet each) would have enough volume for a blast down the quarter mile.

Based on 1.5 cubic feet of air per minute for each horsepower developed, 600 horsepower would require 900 cubic feet of air per minute. 3x80 cubic foot scuba tanks (240 cubic feet) would provide 900 cubic feet of air for ≈ 16 seconds.

600 horsepower on the street is an extreme car and you simply can't use that kind of power for more than a few seconds at a time; blast to 60 from zero 4± seconds? 1/4 mile? mid ten second range. I'm sure my math is off to some degree, but I'm also sure it would work...

Obviously the air will last inversely with boost, but so again, the time under boost to get the job done will decrease... all good fun!

My theme of the whole power game is this: If you want to play, you gotta pay. Going cheap will only cause you headaches.

Theres almost no other place in the automotive landscape where you can spend $5k and double the engines output. Most definately not in the supercharger field.
