Twin Turbo specs

Island_370

Many people confuse turbo lag with turbo threshold. The lag is time to spool once in the right range. Essential on-off throttle in the upper range. The threshold is what rpm do you need to be at to start making boost. But the trade off (and EVERYTHING has a trade off) is that if you want low threshold and low lag, then you sacrifice max power up high. If you want max power (+800hp Supras) then you have a really high threshold and a narrow power band.

I don't know what the kits for the 370 offer. But my previous car was a biturbo. I always preferred the low lag and low threshold---at the cost of overall high end power. I spend very little time over 6K, so why pay money for a lot up there. I prefer to have the power where I use it most. And the low end grunt of small turbos is awesome!

If you want to wave a dyno sheet in people faces, then get a giant turbo(s) with 1500rpm of usable powerband.
