Looks like an intelligent statement


But when a turbine and compressor map go over your head. Then not much I can do about it

 

You win, got me there buddy

 

Take two turbos in sum that have the same compressor and turbine flow capacities as one single and according to you the twins will "****" on the single....... where I say it will be similar


Quite opposite really

 

Oh now you want to discuss maps/flow capacities? I thought LS1tech is full of fail? You should probably go back to the bullet. You might be appreciated more over there.

And just to be clear my "****" comment was directed towards max effort HP

 

How does somebody think that a twin setup that adds up to / is similar to that of a single setup in compressor/turbine flow, etc is going to be automatically better as an end result? I mean it's pretty similar at that point just done a different way for packaging constraints, etc.

 

Exactly.

Ask the guru. He knows something everyone else doesnt

 

I never said of similar turbine sizes, rotary did. The whole reasoning for me to go with twins is to get the greatest amount of Turbine/compressor in my car without having to deal with the consequences.. (single turbo) it's quite simple actually.. What would you rather drive? Twin 58mm turbos or a single 100+MM turbo.

 

As usual this argument goes in different directions becuase often people are arguing two different things. I should have been more clear in my statement from the beginning

 

That's just it you don't get it. You are comparing what a G trim turbine with a 100+mm compressor to a pair of 58mm guys that isn't even in the same ballpark

 

Well that escalated really fast! lol

 

I give up

 

If I was on a computer I would go into detail plot for a given engine and show turbine but not on my phone

Let's simply look at the published compressor maps from a same mfg. Of different sizes

If you look at the 58mm gtx compressor you can see a pair is in the realm of a single 80mm gtx compressor....... not a 100+ lol

"****" for max effort? Again no, if the twins would have the edge it would be in transient response.... not all out power


Yes you get to a point where a single can not stay with twins...... but why is this?

It is simple, turbine capacity.

The largest commonly available turbine out there to drive a single compressor is the G trim.

Compare that single G trim to a a pair of gt55 turbines which are used in the promod stuff and it isn't even close, not one bit

There are a few more points I'd like to touch on but I don't have time or the effort to argue with you right now I'm at work on my cell. Your knowledge of turbos is greater than mine to boot. I do however know one thing, I have been in and around enough single/TT cars to know what works best for me and 99% of the people at my local track and meets. Single turbos are great and have there place but in the end twins take the cake as far as I'm concerned.

 

double the turbos, double the problems... ask me how I know haha

I'm aware of who said it, I was wondering why you would try to compare something that isn't similar? Normally if you wanted to make a point you would compare similar flowing setups with the only difference being single vs twin, not something completely irrelevant.

I commented on it because of these two gems here.

 

Are you? Becuase you seem to be asking contradicting questions and some how labeling them as the same?

Question #1: How does somebody think that a twin setup that adds up to / is similar to that of a single setup in compressor/turbine flow, etc is going to be automatically better as an end result?

Question #2: I was wondering why you would try to compare something that isn't similar?

Let's try to stay on the same page here...

 

I am here just to read the comments.

 

Wow, LS1tech isn't what it used to be. When you throw out stupid comments like that expect to get called on it.

 

I skip reading the new posts on this thread for 3 hours. . . .

 

Here is a good question I'm honestly interested in hearing the awnser to. Besides money/space/complexity of a twin setup why did you choose a single over a set of appropriately sizes twins? I'm generally curious as I'm clearly biased towards twins. Maybe I can learn something today.
