Bigger turbo???

although those are nice numbers. why does the sonic tune hit so late? it's like almost 4600. with that being said you really should compare the same turbos with each other. what would have been nice is if you had the same car with 3 different tuners, now that would have been interesting to see.

the topic was on turbo selection not comparing the same turbos. he also stated going "bigger". if you want to compare the same turbos, you should start a thread on that....or if you are specifically targeting the sonic tuned car, who else has a 35r tuned on the rads dyno to compare with? instead of attacking, you can post your data.
not attacking, just questioning why the power came on so late. and you are a right about comparing turbos so I will retract that statement. as far as my own data I will have that up soon and you can best bet I won't have a post 4k spool

A rotated turbo setup will provide the most flexibility in turbo choices and ultimate power capability when compared to stock location.
Fortunately for me, my ultimate goal is 'drivability,' not maximum power.
I'd like to have a highly potent and fun daily driver that strikes a perfect balance for both street and 'track' use.
For me, and I speak only for myself, I think the HTA Green is the Holy Grail.
And it's arriving this week. Yaaay!

again... bigger isn't always better but if you go bigger make sure you KNOW what you're looking for. You can't generalize turbos since they're made for different things.
drivability is where it's at for me as well. Numbers mean nothing to me unless I can tap that power daily. Also keep in mind with the additional power (not that it matters to me personally) you WILL see a tremendous LOSS in gas mileage. Especially if you boost a lot.
I'd love a GT35R twin scroll on my engine I know the mainland guys do it all the time.

This is completely untrue, and this is the point I've been trying to explain to you forever. The point of the rotated kits are not just in the form of peak power. It's really drivability. If you look at the curve (minus the one that Doll just posted) of the rotated setups, they hit full boost faster and make more torque. The question is just whether you want to pay for that. Becasue they play with larger hotsides, and they are using compressor covers actually intended, they make the power more safely with lowering timing and less boost. I'd agree that the price of a full rotated kit is not in the realm of what an average person would want to pay though. Take a gander over at Nasioc, and you'll see that after at a certain point, rotated is cheaper with better drivability, even with reasonable power numbers.
It really comes down to money in the end. The rotated kits require a large investment up front, but if you compare to how many upgrades one requires to meet their performance--think of people who go from 16g to 18g to green then red---and you'll see that it's worthwhile.
Also boost on the dyno is all based on gear. If you tune in the lower gears, you can hit really high HP figures because the car goes through the load point very quickly (which is why some tuners tune in lower gears to post bragging rights). In higher gears the boost will come on fast, but the engine goes through the load point more slowly and so the tendency for knock is higher. But when you look at peak hp or even spool, you have to look at the variables. HTA green spooling by 3.4 in 2nd gear on an STI...BS...3rd gear on a WRX maybe... 4th gear would probably show full boost by 3k on a wrx.

And aren't these all done in different gears? Isn't blue done in 3rd on an STI, the red done in 4th on 07 STI gearing (or 3rd on an 07 which is still tall), and isn't the last done with a WRX transmission? These are not a good way to compare turbos. Also since the red curve has specific cams--I believe all of the cars have different cams--so I'm not sure what this shows.
But I think you should dispel myths that the rotated setups are junk to drive on the street. The package of parts really is the key. A 35r is well matched to the 257 imho. It's not really the turbo. It's the combination.
BTW, the red is a 35r wheel. So turbine size, compressor size and hotside are all factors of what comprises a "turbo."
