twin turbos

Has any one tryed twin turbo's (1 on each side of the engine, not compound)
You should be able to build 45 to 50psi with less back pressure, smaller turbo's, and quicker responce. Something like what banks is doing with the chevy. under 50psi should be able to still use stock long block with headstuds. is my thinking right or am i missing something

I am not sure if I have seen or heard of anyone doing them.

Many guys have said they might try, but nothing yet.

Really Compound setup would be the way to go

It would be a nightmare to get the Sequentials setup

If I had the money, you could have seen a twin setup on my truck. I do most of my mods in head.

For these applications the compounds are really the way to go. With the paralell twins you can't make the boost you can with compounds. The advantages are that you have smaller turbos that will spool quicker. That's why Banks used them on their Chevy. It's a road race truck so they don't care about the huge psi of boost but rather getting it instantly. You'll also likely have as much or more drive pressure with it set up that way as well.

thats kind abeen the point that all of us are trying to make that have thought of the ideah of paralell turbos some of us would rather have lightning quick response. something that fun to drive rather than some one who wants to hold the brake and the throtle to the floor for 5 minutes and waiting for the green light so they can blast down the track at insane speeds. most of those trucks are not practical for street use and are verry un responsive on the bottom end. personaly I bought a diesel for the low end power not huge insane number of boost on the top end.


ive actualy thought about doing the paralell turbos with a combined 30 lbs of boost but get high compresion pistons. that way you wouldnt need high boost and the low end response would be better with higher compresion pistons.

i dont htink higher compression pistons would work. remember the old IDI's that liked spit headgaskets out? You want lower compression and more boost. Use boost to raise your compression ratio back up. Mine is sitting somewhere near 16:1 compression.

the problem with diesels low end response is the decreased low end compresion. you have to build boost before you have enough compresion to get response. as far as head gaskets go im sure if peope can build motors to handle 100lbs of boost surely some one can build a motor to handle 1 more point in compresion with 40 lbs of boost.
