Its not the compression in relation to usable power that you feel is misinformation; its the acceleration rate that tends to change, that a dyno just doesn't show.

And 5400rpms can be done a lot faster with a slightly smaller open turbine housing with the same 80mm exhaust wheel you're using now, with any negligible increase in turbine exhaust backpressure as opposed to the divided .91 A/R turbine housing you're using now. ...

So, no misinformation, just differing ways to make a build for a differing purpose.

I pretty much only use my car for drag racing so it's not as big of a deal for me, but I could happily drive this car on the street(and I do some). I don't think I could ask for a much better powerband for my setup to be honest. A friends k20a car spools slower with an s362 than mine. You always mention the dyno like it's somehow much different from the street but I don't feel that's correct with the dyno we use.

Type of dyno is irrelevant (Chassis/Mustang, Dynopak, Dynodynamic, etc). There are many aspects of a car's behaviour that just isn't taken into account in one gear, with optimal conditions in a snapshot scenario cannot account for an application's true behaviour in several conditions. Now, that doesn't mean it can't assist in that behaviour, but I think too much credit is given to a dyno graph when other transmission, exhaust energy, and other phenomenon can't be taken into account.

What works for you, may not necessarily represent everyone's needs, even in street/drag situation. But, if it works for you... it works for you.

Everyone seems to quote response times based on a 4th gear scenario. no one seems to remember that the car has 4 more gears. It might be cool to say I make 28psi below 6k in 4th but I'll bet you that 2nd and 3rd gear probably suck. especially when you aren't making much power in 1st and then the huge turbo suddenly and rapidly starts making pressure in 2nd causing wheelspin, then you shift to 3rd and the same thing happens but even worse since this is the area that most large turbos start to build full boost

everyone can agree that most turbo setups don't really do much in 1st... but if I can't have decent response from 2nd gear on up then what's the point. not everyone drag races, it's not always about making full boost at wot and staying there. real world driving is going to always be mostly part throttle, light load.

I don't care how the turbo responds in 4th wide open, I care how it responds in 2nd and 3rd at part throttle. given that most of the setups here are dedicated street cars those people should also be thinking the same way.

it doesn't matter how much boost you make or when you make it on the highway... it matters how the turbo responds around town in lower gears below wot. I can personally tell you that driving a car with a huge, oversized turbo on city streets is no fun, typically there's 0 midrange power production.

if you want a topend power drag car then run a big turbo, if you want a fun street car that actually has a useable powerband then you need to come back down to the realm of reasonable and run a much smaller turbo.

The guy said he wanted 500whp. Good luck making a true 500whp on a b16 with a small, responsive turbo.

The gtx turbos are awesome.

It depends on what your goals are. If you spent a lot of time at the track, the 35r isn't really a "dyno queen" lol. But I agree, I hated the 35r setup on such a small setup. The 57 trim car was much more fun to drive and had way better midrange. That's why my new setup is using the S259 turbo, to have the best of both worlds. Shodan knows his ****, and will definitely help you out in guiding you to buy a proper sized turbo, not something stupid like an S366 or 62mm that would be lazy on your car. I'd look into a 5858, S259, S258, etc.

With good internals anything is possible. I'm thinking of doing an 84mm b16 GE sleeves with a pte6266 and shooting for close to 700whp. For those who think its not possible

i have a b16a2 on rss sleeves/e85/id2000/9:1/crower rods/stock p72 head with gsr cams/ on a 6265 at 35psi i made 755, and on the 6766 i made 810@38

Why? that plenum is huge for a low hp street car.

you'd be better off with something like a Skunk2 pro series.
