How much power to expect with twin 60s?

I'm looking at installing some commetic gaskets and dropping my compression to around 9:1 then installing some twin 60s. I'm just curious what I could expect to see on pump gas?

I'm runing two Sc61's and have 590 rwhp [Dyno Dynamics] at 14 Lb boost..
By no means the turbo's are maxed out.. At this power level the in tank pump just couldn't supply enough fuel to surge tank.. So tune stopped there...
7.8 compression...

Well, I do believe that the 60mm is good for 550 flywheel power....So two of them should do 1000-1100 flywheel power on an efficient motor with the right exhaust housings

tfs coupe that is not exactly so one turbo that makes 550 hp and add another does not double the hp output though it will make more power but it wont double it but twins are cool and work great when done right

I don't think it would come close to 1k but am hoping for more like 6-650rwhp.

why wouldn't they come close? they will go well past the 1k mark. mine now makes 750rwhp on pump gas, twin 61mm turbos, 14.5 psi, 10.5 a/f, 10 degree timing... lets just say theres more power to be had! my car has a VERY modified version of turbohorsepowers twin turbo kit. turbohorsepower ended up making 1200rwhp with twin 61's at 28psi on one of their customers cars and already my car is making more power psi for psi.

trust me, twin 61's are the way to go. plety of power to be had!

as a note, turbohorspower made just under the 1k mark with twin 57's.

Gotta love the 4v. My longblock is for sale so I can buy my friend's built 4v with an 88mm. The twin 60s are my backup plan, lol. I didn't realize they could make that much power but since my car is my only transportation I don't need that much hp. I'll eventually convert it to a 4v.

THP's numbers were elevation-inflated SAE corrected dynojet numbers. That 912 RWHP 2V car made that power at 27 or 28 psi SAE corrected in new Mexico. Think it's THP's amazing engineering that lets that car make about 150 RWHP more than any other twin 57-trim 2V car that has been dyno'ed at lower elevations? Same with 1200 RWHP through 61mm turbos. That is absolutely MAXING them out on a RWD car, and to make that kind of power to the tire on an uncorrected dynojet at or around sea level you would be looking at around 34-35 pounds of boost. To max them out at higher altitute (read: new mexico where the THP car was dynoed at) you would be needing to push nearly 40 pounds of boost. Dynojets hugely inflate turbo cars horsepower numbers at high altitudes.

With that said, I think 600-650 on pump gas from a built stroked 2V with turbos is a realistic goal. Maybe 700 if you like to push it!
