I'm currently running a vortech t-trim on my 383 lt1 stroker motor. Seems like the big power usually kicks on late rpm like 3k and up starts pulling. I was thinking about going with a Procharger D1SC unit... Would there be a huge difference in performance.. Would I have more instant power from a stop/roll over the t-trim. Just want something to give me more power at lower rpm then the t-trim

I believe the D1SC would start to build power at 3k also. Don't quote me on that though.

Is there supercharger unit that will build power quickly in lower rpm??

you can pulley the unit for max impeller speed and install a waste gate to bleed of the excess boost.

You are never going to get a big low-end punch with a centrifugal blower. It would be a lot cheaper to hook up an inexpensive nitrous kit with a 25 or 50 shot and use it through ~4500 rpm. Changing from a T-trim to a D1SC will net you almost nothing - they are very similar in size and cfm rating.

Even using danbap's idea from above just makes the boost rate go up a bit faster - you really can't pulley well for this unless you get a 9+" crank pulley - and you end up wasting work by spinning the head unit and dumping excess boost.

THe other thing you can do is keep your T-trim and build a 427ci motor to strap it to
Low end will not be a problem, traction will.

I agree with "DeltaT" if you want more low end grunt, build a bigger stronger motor..
My d1sc kicks in at around 3k but my low end grunt is pretty good, plus when do you need grunt under 3k? even from a dead stop you are only beneath 3k for a hot second?

FYI: When you add forged internals to these engines and run a smaller blower pulley on a centrifical supercharger to up the boost, you'll notice the boost comes in much sooner as the blower is being spun faster. Bob

What size stall you have?
