i know of a turbo that i actualy plan on using on my bike, it is a turbo from a honda cx500 turbo from the 80's it is made to go up to 18.5 psi and will boost you 75% horse

if you're running a turbo at 18.5 psi, and you're only making 75% more hp over stock, your set up has some serious issues

Whats `Dow``? Do you mean `Dough`...as in slang for cash, or is it something else?

actualy the turbo that you are looking at only has a 2 inch spinning wheel causing high psi and not much horsepower to add on your looking at about  85 horse on a rejet motor unless to have some pretty decent mtor work then your pushing aound 100-110 costing you more than the bike is worth so dont go trying to make me look dumb i work part time at mustang specialties and i install twin turbo's atlease once a month and ill tell you what a cx500 turbo can do, if you wanna act smart 18.5 psi on a small turbo like that is not much so learn your stuff before you decide to talk shaZam!, other wise go home and learn your stuff then talk shaZam!, in 1981 the cx500 turbo was perfected for the pulses of a two cyl motor, causing high compression  and decent horse upgrade to make a smoothe working bike that did not require alot of maintenance, this is not a honda civic with a 1.6 dohc ls Vtec making 200 horse out of a 6" spinning wheel, this is a motorcycle reving to 10-11k constant while driving fast. so like i said learn your stuff than talk shaZam!.

I think he is implying that if your running 18.5psi and your only getting 75% more out of thoe motor you have done something wrong..  our motor puts out about low to mid 40's with a pipe.  If your running 18.5 psi on the setup and only getting 75% more then you have done something wrong... thats what he is saying there is no reason why you should need to run that high of a boost and only get about 75 horses out of the bike cus thats what you told us...  cus I happen to have a caculater that says it knows how to take 42 horse power and hit the little X button and type 1.75  cus i want to add the 42 horses that i have back into it and it gives me a a number of 73.5 now you give that number a +/- 5% and you get any where from 77.2 high to 70 low side on your horses... now you tell me have you done something wrong cus I think i could get that out of about 8-10psi... Oh and what honda Vtec is using a 6" wheel you got to kidding me that means you put on big rig turbo charger and using it way out of its compressor efficiency...  Only getting 200 horse damn 1.6L stock makes 160 at motor ohh brother I'm thinking you should probably talk to your boss about a pay raise at that part time jobby job of yours cus he has got the turbo guru Everybody  take a look I will bow to this guy



Don't get me wrong I'm not on her to throw mud but when you put out things like that your going to get bashed... if you look at the page before I had to clear up somethings before I continued and I think were all trying to get on the same page. But if your out in left field were going to try and call you in and set it straight thats all. We aren't picking on you for your turbo choice.  It is a good choice what they are bashing you for is the 18.5 psi and getting only 75% gain.  Sometimes it takes an edit to clear things....  and sometimes you can clear things up rather than just fire back more nonsense. Take time compose your thoughts.  I have the same problem  sometimes i don't cook the beans long enough but a simple explination will get you further than bashing people.

with a proper set up(including a proper sized turbo for the flow ratings of the motor) and intercoolering, etc, you should be seeing a ~10% boost in base hp per psi. If your turbo is spinning at 18.5 psi in order to cause a 75% increase in power, you have either the wrong turbo for the motor, or another serious issue.

Yes, a small turbo like that may not flow a lot of cfm, however, the cfm is taken into consideration when you chose the turbo for the motor.

Proper size is key.

1.6 lsvtec learn your shaZam!

ive got a 83 yamaha seca 650 turbo sitting in my yard. thinking of the engine transplant to the maxim 650. the turbo is the cutest thing. love the factory sealed carbs too.

Extactly  I miss the LS  but your still come off sounding retarted. hmmmm LS 1.6........ cus stock an LS Vtec  should be a 1.8 block witha 1.6L head.....  now math  aside you start with a 1.8L block your going to get about 1.8L block cus thats what you started with  the head may drop displacement a little but its not going to change the car .2 Leters Link explaing an LS Vtec http://members.tripod.com/crx2/motor.html   Cus I could build an N/A LS Vtec to 200+hp motor with out the turbo...

Let me start with a nice little parts list that I helped a buddie with his motor...



Motor Modifications:

11:1 CTR Pistons
Cams
Titanium Valve Spring
Titanium Valve Spring Retainers
Port and Polish Head
Header
270cc Fuel Injectors
Shaved Head and mill  .020
Shot-peened and Polished stock rods
Micropolished Crankshaft
Skunk2 Adjustable Cam Gears
Lightened Flywheel Fidanza
B&M Fuel Pressure Regulator




and with coments of a 6" spinning wheel like I said again another retarded statement I don't know why you would put something with a 6" trim fan in a motor  like an LS...  its wayyyyyyyyyyyyyyyyyyyyy tooooooooooooooooooo  big....  so do you want to come back to class cus I'm sure if you want to be schooled than I can be your teacher. Its ok not to know and I'm the first to admit I don't know everything and I'm sure not a honda motor guru but. Again your just babling and not clearing anything up that your talking about. If you go back and explain the things that your doing you will get alot furter...  Class dismissed.


Now back to the turbo post. rangerbrown make sure when you install larger Oil cooler to put check valves in the line cus you don't want to screw up the sump of the motor Do you know what i mean. one way valves that when the engine stops running it will hold the additional oil in the cooler. Also if your going to go to all that work you may want to install a regular style oil cartrige that way your taking off less shaZam! every time you need to change the oil then you can skip oil fiter in block maybe every two or three changes depending on your comfort level. Also you could put in a larger oil sump tank to maybe keep another quart or two. the stock system on your bike should be able to move it...  The check valves are a must to increase your oil sump cus other wise we all know gravity and liquid will find the lowest point. being the bottom of the motor. I hope that helps if not I could draw a little diagram..
