lets see. i got ported primaries and bridged secondaries(conservative bridge, for the street). now if i could get it to start i could actually tell u how its doing. oh, yeah, NA with a dell. hopefully fuel starvation wont be a big issue.

That's exactly what I was thinking but with a bigg ass turbo bolted to the side.



Where's Ito, I'd like to hear his opinion/experience on this https://www.nopistons.com/forums/pub...#>/biggrin.png

well guess what it blew a hell of a lot of smoke, we had to clear the garage 3 times, god damn wind blew it back in, but it started.... :bigok:

need to fix the idle and a few things, but it should be out soon.

I was currently running that exact set up , bridged secondarys , streetported primarys with a T70 - 1.15 a/r , p trim turbine , I worked ****** great , that turbo would be spinnin hell hard at idle creating positive pressure and would hit 8psi (wastegate spring pressure) before 5000rpm.

I had it tuned to 8 psi and limited to 8000rpm and ran it that way for about two days then the turbo fucked up ( stopped turning) , the power and response I felt was increadible , The front of the car would be up in the air like a power boat , my intention was to run 25psi with methanol/ water injection @ 9000-9500rpm.

Now I am going with a TA51 / 45 turbo at 25-28 psi , should have it installed by tomorrow, will let you know how it works.

What happened to the turbo? Was it brand new?

yeah, you dont need a bridge on a turbo car, just a bigger turbo

I thought the phrase "half bridge" was only applicable to 6port motors, when you bridge port the 5/6 port area, but leave the main port unbridged. Aren't turbo motors 4port?

half bridge is when you only bp the secondarys in the end plates, and leave the primaries unbridged
