going to turbo charge a small block and want to know if to use two turbos or one,someone said two T70 would do better than one big one.Any comments

 

2 t70s would put you in the 8s ez(with a good tune) You can get a single turbo that'll put you in the low 7s hi 6s...

how fast you wana go?

 

Accel dfi,T70 -two of them,brodix pro1 heads,carillo rods,scat crank,JE pistons. and world products small block. Waiting on exhaust manifolds but like i said every one tells me to get rid of the two T70 and get a huge single.What size single should i get and with what size back end.

 

if the class you race in allows twins, I would probably go that route.

 

all i really want to know if i can get lower ets running a huge single as compared to two turbos,looking to make close to 1500 hp with a small block.Where i live we dont have rules or class restrictions,just run what you bring.I want to run sixes in the quarter.

 

Start looking at some 101 or 106mm if you go singles. Also take a look at the times the Blue Oval guys are running w/ Cartek's Dominator kit.

Find a different message board. I think you are starting at the wrong place .

Good luck!

For your hp wants (1500 hp) I would stick with the t-70's or step back to a set of t-66's or t-68's. Reasoning on not using the big single is to spool it up. A 101-106 mm turbo is going to produce well over what you are wanting (1500) I have a set of 66's that i had on my car and was going for about what you are but with a few changes i went with a single big turbo to go all out. (t-100)

Basically you can accomplish what you are after either way. I have seen twin t-70's make 1670 hp running a air-air inetercooler setup.

Imo its going to be all in the tune and how you set it all up. I choose to use a lil less boost and run more compression in the motor.

Who did your headers?

If your going to run a 106mm, just make sure your motor is over 400cid. spool up time takes days with anything less.

 

was that in a white regal with a sbc

 

No a mustang with a 306 ci setup.

Have seen turbo's in the t-70 series in twins on a black gn (not chow's car) as well as some others, but the one I am refering to is a mustang.
