it runs 100x better in cooler weather. After I got done putting the kit on, there were a few days where it was 40-50 degrees outside and it seemed like it was a different truck then


Toomnymods-- thanks for the tip on the A/W intercooler, but I already bought an A/A intercooler

 

Well there you go. Probably getting a few degrees of timing back from lower IATs. Plumb up that intercooler, get a retune, and don't leave the line off idle and you should be good for low 13s

 

Where did you come up with this? If anything it's the opposite. A few hard-core turbo nuts who've gone low 11's and high 's swear by stock converters.

 

All depends on the setup, if the engine is overcammed or over turboe'd the setup will like a looser TC, a properly sized DD setup will enjoy a tighter TC.

Running no intercooler is fine if you live in areas where it never sees 85 plus degree days... And in the winter it will be fine. But in the summer heat it just cant handle the heat at optimal timing. Now if you can tune yourself you can compensate some for the iat tables. But in TX you will ptobably have to run ic for sure

 

I was speaking from experience of the way my truck runs with a 60 turbo on it. Being that his truck has a larger turbo than mine. It would probably benefit alot from have a larger convertor put in it.

 

Just saying I've never heard of a stock stall preventing someone from hitting boost in 1st gear. A looser stall would definitely have that effect though.

 

The stall speed need to be high enough to get the turbo to light, after that it's good. If you can't light the turbo, it won't make boost well at all foot braking it. My dads 72 Chevy truck is that way with a stock stall/4l60 with a T70 on a stock 5.3 Won't hardly make 1psi standing on the gas and brakes but as soon as I let it go and the RPM comes up a few hundred and it lights almost instantly. But a turbo does need enough rpm/air flow and load to light and become efficient.

 

I know what your saying about trying to light a turbo off when on the foot brake at the stagging lights. But I've never heard of a stock stall being the culprit for preventing a turbo from hitting full boost in 1st gear. Just like your Dad's truck, once he get's going a little then the turbo lights off pretty quickly.

 

Hey guys, I tried out the syty shuffle, I'm not able to build boost on it, but vacuum does go to zero (tires start to spin no matter how hard I hold the brake). Do I still need to try to get it into boost? or is no vacuum 'ok to work with'
