Actually most of you guys are right about your many points as to which is better. why do you ask to most people use a big single turbo on say a supra. and then twins on say a 300zx tt??? ill tell you just because i had a z32 its because your turbos dont stay spooled correctly and more prone to boost spike with unequal turbo exhaust manifolds. now. thats why you dont see many single turbo 300s. yes there are a few but they pay the extra for the high priced manifold and yes the numbers go from 400 up to 800 hp with that bigger setup and as for spool?? it all depends on matching your ar with your exhaust cfm rates and plot them on a compressor map. i see alot of people using the t28 and t25 turbos. well these turbos are very small and if you ask me they are not a very wise choice to use as is the t3 or t4 hybrid and what are the ars these turbos are using i havent see any post stating what ar they are using. are you just putting one on???? now the ct26 off the supra is a good choice as i found when i plotted it on a compressor map and it shows boosting just over 3 grand and dies at 7 thats awesome for our car. low end tourque with boost at the top end. i dont have a phd in turbo setups and yes i am doing the unequal length manifold setup and yes i am doing a single turbo on the duratec but the fact of the matter is on a v6 its much wiser to use twin turbo because of the ease of having shorter manifolds and controlling boost spike. on a inline motor single turbo on a v motor twin its just smarter and more easily configured. the contour well thats for you to decide wheather you think you can find a spot realatively exactly in the same place on both sides of the block for turbos that we and street flight didnt see. and yeah ive seen two turbos on a contour too bad they were electric and it was a 4 banger. worthless

Depending on how much power you want to make and if your gonna be able to affored the extra thousands of dollars, i would rather have a twin turbo setup then a single on a daily driver. Twin turbos spool up faster, i know 2500 vs 2800 but if you are at cruising speed there will be more of a noticable difference. By having 2 turbos, you could have a slightly cooler intake charge, but in order to do this you would have to oversize the turbos a little, which would make it spool like a single turbo, but you would have a little more power because you would not be working the turbos as hard. In the end, there is only so much power to be made on pump gas, but if i had an ungodly amount of money i would be all about a twin turbo contour.

No amount of money can buy you more space in that little engine compartment...

Inless you make a ray gun that'll zap the turbos to miny size, so they'll fit between the firewall and the motor  yeah no way a turbo will fit on the rear bank without alot of cutting ALOT

1. Please explain your logic behind that thought.
A Single turbo is driven by the exhaust energy of Both banks.
Equal Twins are each driven by only One bank respectively therefore get half the exhaust energy.
2. Have you ever "cruised"???
Who cares if boost spools at 2500rpm vs 2800rpm because it's so far down in the rpm band (I.E. below the powerband) it won't make a real difference.
If you really want to accelerate you won't be driving in tractor range anyway. (I.E. below 3000rpm)
