id like to know where you found a twin turbo for 5k first but second, it depends on what you wanna do with the car, a twin turbo isnts usually needed unless your gonna turn it into a full drag car, usually one turbo is enough.

nvm, i know what turbo you are looking at, your looking at an STS turbo, i can tell you now that twin turbo system is more then 5k, the single turbo system alone is 5k, im guessing the twin is around 7k

the Saleen S/C is a really good S/C. Its the only one i would use on my own car unless i was going to turn it into a drag car in which case i would go out and buy a big Kenne Bell Twin Screw S/C

My twin turbo system is not for a dedicated race car. Mine is street car and daily driver. I've got the twins, a PI converter and a Spydershaft driveshaft. Car runs 10.88 at 128 while getting 20 mpg in town and 26 mpg on the highway. Now, if I want to go faster I can just turn the boost up and I've got race car power. However, this kit is not cheap.

As for your setup.....if this is to be a a real live daily driver with some track time the Saleen kit is very good. A twin screw setup will be nice for daily drivers that see some track time. Plus, they have some room to grow if you want to go faster in the future.

If I were given a choice between the STS system and the Saleen kit......I'd go Saleen.

Id go saleen.. something about the rear exhaust turbo setup just screams machanical failure.. think about the oil lines that have to make it all the way to the rear of the car..

Saleen over STS for sure. Powerhouse over Saleen

If you just want a street car get your self a Saleen charger they look clean under the hood. Affordable and get it from JDM they are the only place I would have tune my Saleen.

Whipple HO for a daily driver. The car idles and drives like stock until you hit the loud pedal. Instant torque without having to spool up our power shift. Set up your suspension right and leave your gears at 3.55 and traction will not be an issue.

how much torque do you really need :) at 2,000 rpms :) I have seen some Turbo system making some monster torque at low RPM's.

:) Boost lag is like saying Ladies first

The reality is some feel big power is worth waiting for, others know timing is everything. :)

It is more in the linearity of the torque curve that suits a daily driver best. Twin screw does that best. That is why AMG used IHI twin screws in their 32s and 55s; to simulate the feel of a big block. Boost lag is a reality in turbos and big Prochargers. Impressive at the straight track launch and great until top speed is reached by the Si97 chassis and gearing. If one wanted to be king of the highway, then one should've bought a Supra. :) A twin screw is king of the daily drivers because of the torque delivery. That is why FRPP chose Whipple for its Super packs. I believe a Whipple HO 4.6 S197 does pretty good against its expensive GT 500 cousin in all around performance with a tuned suspension and power to weight ratio (3450 lbs vs. 3920 lbs, respectively) for $30K less.

I'd ask yourself what you want to do with your car?

If you're going to race it all the time at the track, get a turbo. Twinscrews have a limit to how much power they can make.

If it's just a street car, get a twinscrew(KB, Whipple, or Saleen). Less maintenance and better reliability.

its subjective, some people say superchargers, others say turbo, i would say the supercharger is harder on the car due to the strain from the belts but the turbos usually run alot hotter as well so both have their pros and cons but in my opinion with an intercooler i would go turbo

yes but the rods will give out way earlier then the crank will :) what it comes down to is that its pretty minimal and I would not let that decide which application you should get.

Get what you think is more cool looking, best sound, and what you will be happy with.

What it all comes down to they are all equally great in there own ways for the mid to low power range. They are all capable of making a good 10 second car and will change your car dramatically.

Now if you want a 9 second 1000 horse power monster then a turbo is going to be your best application because you can just turn the boost down for street driving, where with an S/C you cant.

What do mean? I can change my boost level any time. When I'm driving around town I have no boost at all.

That is unless I mash the accelerator. I can be driving around town in 4th gear at 35 MPH, that puts me somewhere around 2000 RPM, normal driving speed and RPM. But when I mash the pedal, still in 4th gear, I have an instant, on demand 500+ pounds of torque. It's like driving around with a big block 429. Turbos can't do that, neither can cetrifugals. It's just physics.

If I don't mash the accelerator I'm the same as any naturally aspirated car.
