that picture of Ernis twin turbo engine, is real nice, Except there is one problem. The back turbo is goin to get all the heat from the front turbo, causing the rear engine to run richer and loose power, You should try to put them more like the factory FD brings them,, one looking forward and one looking back, You would probally gain about 100 extra HP. But NICE work

BTW.. I have been in the hospital since Monday night. I had some horrible flu hit me. Then, my diabetes went out of wack. I have hijacked a nurse's computer to check out the updates.
I am suppose to be released tomorrow (Thursday). So, Marcos, if you have been wondering why I haven't made my daily calls; thats why.
Did you get my suspension kit?
Take care,
Mike

Well I guess I know where my money is going over the course of the next year....I'm definitely interested in a kit although to have it tuned would be a bonus...I have much that would work with the 20B as is so it may be more cost effective, and fun, to slide everything in myself :-) Christ. I disappear from the 20B forum for a month (or two) and look what happens.

Sorry, but a twin setup is more efficient then a single if setup right.. A single is just much more simple..
The main reason a twin setup is more effcient on a 13B is because of the radius of the wheels. The smaller they are the less weight towards the the outer parter of the wheel.. it is able to spool quicker..
So if you have 1 huge wheel, it will take longer to spool then 2 small wheels. And it works out well on a 13B because you have 2 exhaust ports.
Hope that made some sense.. kind of a ramble...

Because a huge wheel is harder to spin then 2 smaller wheels, even if the 2 smaller wheels flow the same as the 1 huge wheel. because as the wheel gets larger the unsprung weight becomes more (i think it is unsprung, might have that term wrong.)

Zach,, You are wrong in that one, It take the motor more to spool the twin setup than it would take it to spin just one, But once the twin is in Boost it is much much better, You want to know why it take the twin more time to spool,
1. Both of those wheels weight more than just one of a single turbo. (so the more the wheel weights the more lag you have, I use twin, but my wheels are Billet and weight less than one Single turbo wheel, So i dont lose out to lag)
2. it would take more air, to spin both of those wheel ,, than it would take to just spin one

You really need to look at which turbos too. Stock twin set up out spools just about any single because of size, but loses out on mass flow really quick once the revs get going.
For comparable mass flows, I still am not too sure which would out flow which. I would think that you would need to look at efficienies, how the twins are manifolded and operating pressures.
It would seem to me that if the twins are better throughout the RPM range, then you have the wrong single for the application (and comparison).

That's true, Twins are 100% better like i said,, but for a daily driving street car, i would go single, a nice big single. But like i said, if it's for track and street then i would go twin.

I just ordered my Unorthodox/Tilton 2 disc setup. I decided to go with them do to parts availability. They offered many options in disc material and spring rates. The can also make discs for other input shaft splines. IE GM 26spline(T56), or 10 spline( Jerrico, G-force, Richmond, ETC.) Thats why i picked it. I costs about the same as a Cusco w/ adaptor kit. I'll post pics as soon as it arrives in 2 weeks.

Like you said it depends on the wheel's weight.. But one thing you are forgetting is that weight further from the center of the shaft makes more difference. And when you try to spin it at close to 100K RPMS it makes A BIGGER difference.
It is just like wheels & tires.. Would you take heavier 13" wheels if they are only a pound or 2 more? or would you take a little lighter set of 19s?
Which would cause more usable power loss? the 19s would. cause they have a larger diameter.
But ALL of that is still dependant of sizing it correctly..
Note: on the wheels. the ratio would also make a difference. Not just the weight.

Correct, but you get the point, That's why i said, my twin turbo in my race cars have billect wheel that weight less than a big single, so i get the advantage of a twin turbo setup, with out the lag..

Is that with 20B? If so what is your spool up time and power with what amount of boost? Let's see some pix of your intake/exhaust manifolds with some prices.

I've been trying to post pics for three days, including about 10 minutes ago with no success..tried three different browsers, etc...I'm sure Marcos is getting frustrated. :-)

Marcos, email any pictures you have to me. I will host them. This includes videos too.
