Why do people convert to a single turbo on their 3rd gen FD when its twi turbo? IDK i think that twin turbo is way cool! But a single turbo like a t-78 is supposed to be way faster than a twin t44? how? thanks for your help on my stupidity what do you think?

 

wow, not this question again. It has everything to do with the amount of air flow the turbo can make and not the psi it makes. Not to mension heat given off my the little turbos spinning like a mother ******.

 

twins is nice because it is convienient for driveability, but if you have a properly set up single FD you can make tons more power without almost no loss in low end power (plus benefits of less heat, vacume hoses gone, ect ect ect)

 

Stop by the shop I can more than show you what the differences are.

Exactly. A GT40R should show him!!

 

Besides reliability you get tons more power. so yes, stop by their shop and they will show you.

 

the shop what the hell? wheres this shop!?!?

 

I know that a twin set up will create more heat, but wouldnt the twins spool quicker than a huge T-78 single set up(with less heat?) .... and they would both run the same psi too

I don't buy it... properly matched non-sequential twins should be equivalent (or maybe even better) than a properly matched single big turbo.

At least in theory, I haven't investigated it, but I would think twin turbo on a two-rotor (each rotor dumps to its own turbo) would be preferable to single turbo in terms of power and overall driveability.

 

in theory, yes.

a lot of people do not know how or do not want to work on the sequential system. Slapping on a big turbo makes things much easier. You go from 50+ vacuum lines to...what, three? Four?

 

The problem with this is the turbo's are too small and have small eff. windows to work with. So turnig them up too much generates heat not to mention dealing with the crappy manifold design.

It could provide a broader power band but keep in mind you are now adding bigger turbos(small singles) and plumbing to go with it as well as complexity and heat. This is OK but a properly sized single will work pretty darn close to the same performance with half the mess weight and heat.

Look at the torque curve of a stock twin setup.

The term "torque spike" comes to mind.

 

Yeah but now each turbo is only responsible for flowing enough air to feed 40 cubic inches instead of 80 (one rotor instead of two)

 

Are you suggesting two sets of stock twins?

 

I'm not suggesting anything, I'm far from an expert, but I don't believe that one properly sized large would necessarily be better (and might be worse possibly) than two smaller non-sequential turbos.

 

As long as the twins have room to breathe (Read: not the stock manifold) they would defintely kick ***.. I'd think twin TO4E's or similar..

Ask IGY. He has twin TO4S turbos..

 

twin T04E's??? crap man.. I'm running a single T04E 60-1 on my TurboII and it's almost big.

 

stock twin manifold is good for more than 400rwhp.

Don't the twin TO4 guys use T3 exhaust sides?
