Yeah as soon as it goes into closed loop just watch the fuel trims.

 

Yep that's what I was thinking.

So if a person wanted to match the power of a s480 or the like with twins on a 370 what size do you guys think would be ideal? Looking at tc61 and tc66 maps the 66 looks perfect. From what I can see the both turbos would be in the heart of the map but the tc66 and 370 fall right in the center of the heart. From lowish boost to high boost. Would a 66 spool that much slower than a 61? I would guess 65mm turbines and .81 t4 housings. Make them divided tangs with quick spool valves and you would have a monster setup on your hands. .

Just throwing things out there.

 

No need for quick spool valves on a pair of divided housing T66s. At all.

 

this is true but man, think of that spool time. lol

 

Lol I agree it is tempting but that could be added at any time later on. Drove a friends Z06 with Twin 6266 pushing 750whp it was instant boost basically lag didn't exist at all. Wasn't my cup of tea as it didn't feel turbo-ed at all.

 

9 second ZO6 not your cup of tea. That hurt!

 

don't get me wrong that thing was beautiful car overall haha.

I was talking about the turbo's behavior compared to my truck. My truck takes a probably 1 second then it pulls like a train.

The vette was instant boost and strong pull for probably 1000 rpm then just feels steady.

 

Time? If you have found a way to record negative tenths of a second maybe LMAO! Really, that combo would feel like a supercharger at anything over 1500 rpm. And if the cam and gear are right, even off idle it would just blow up the tires. A needless expense and complication.

 

So 6665's would spool that fast? That's nuts.

 

with spool valves, yes...it would be nuts.
