I'm planning my fuel system for when I take the next step and put in a T04E and I want to know how having such a big flow difference between the primaries and secondaries affects drivability. Do any of you with 1300/1600cc secondaries experience any kind of stumbles or anything when they come online?

Also, what size primaries do you guys with big single turbos run?

BTW this is on the 90 TII

 

i like the 1300s but i dont think you will be able to run full power on them...go with the 1600s

I have 550's (prims) 1680's (2nds) ran by a Wolf EMS 3 bar and a Garrett T60-1 (.70 comp/ 1.00 A/R turbine).....

It was a little hard to get the stumbling dialed in at low RPM's, but under boost, when they come on its very abrupt hp....Its really cool around 14-16psi.....

I tried 850's in the prims but didn't care for them as much as the 550's.... my .02....that was a little harder to dial in for me....

91 turbo II

I'm running 720/1600 controlled by the Wolf3d.

Just like the previous post, it was tricky to dial in the low load/low rpm area's, but inder boost they work great. Just takes some dyno time, that's all...

 

I was going to make it to a dyno this Summer but decided that I am going to rebuild my motor and or port it more, so I thought I'd get it close and run it for the Summer......Its running awesome now
