I am stuck between twins and a single if I go the single I can upgrade the cp3 right now as well. If I go twins It will be a long time before i will have the money for a CP3.

What I want to know is how everyday drivable is a single 66. I know some people do it , but how laggy and smokey is it for real. I dont tow very much maybe 5k-7k 5 or 6 times a year, but me or my wife do drive the truck everyday.

I will be running a TST and either a smarty or BDDL on top of 90 hp DDP injectors. at the track and probably just the tow setting on the DL for everyday driving. please let me know what you guys think.

 

I have had an II SPS66 for 2 and a half years on mine now. With the proper mods (enough fuel) and tc/transmission (no mushy stock tc) mine is just fine for me. It is a little laggy and smokey with a decent load, but even then manageble. Daily driving takes getting use to, but with proper supporting mods it is fine. I am glad that I went with the SPS66. Most now are going with the Silver Bullet that I think will spool a little quicker, but I am fine with mine.

My mods are similar to what you are looking at minus the sticks which should even make it better. Just my .02.

 

my truck is a little smokey but you get to know how to drive and it is hard to tell the lag.

 

mine is fine but i have a standard tranny

 

also do you guys think somthing like a silver 64 or the 64-71-13 from high tech would cool my set up ok at the track, or is that asking to much of a 64 sized turbo.

 

It sounds like we'll have very similar mods. The smarty and the DDP 90's will make the single 66 spool great if you live anywhere near sea level. Not sure how other 66's compare, but I really couldn't be happier with the silver bullet. TST and injectors alone will be enough to spool the 66, with very very minimal smoke. Add the smarty and you have almost instant spool up with light to heavy black smoke depending on how you roll into the throttle. Where are you located? elevation?

 

I am in las vegas nevada

 

I'll be there thursday for SEMA, but not with the truck. I'd say you'd be happy with the single 66. I drive mine every day (04.5 with 137k on the clock) and am very happy with how it performs. When I know I'm going up in the mountains (tahoe, reno) I usually pull the smarty off and it won't smoke.

 

mY 64 COOLS REAL WELL can't get over 1300 egt I'm about to do stage 3 pump and 150hp stixs we will see

 

Go with the silverbullet, and then get IIS to do some mods on it, I think it costs about 300 or 400 but it makes the turbo spool even faster, it is amazing

I just got my SPS66 installed on the truck and I love it decent spool up i dont get much smoke unless I get On the throttle real hard.
It is a streetable turbo.

So with enough fuel, someone could tow 7-10 pounds without too much worry?

 

sure 10 pounds should be not a problem

 

Whoops! I meant seven thousand to 10 thousand...I think I forgot the K....

 

I know but I had to jump on that one
