ok guys some single questions

[dommel01]

my brother had his truck built with dual fuelers an 100% nozzles, it currently has an s472 on it, its very responsive surprisingly, but he is considering going up to an s475. my questions are what would be a better sized turbine the 83.5 inducer, 74mm exducer or the 87/81, also exhaust housings, it currently has a .90 on it would there be any benefit from going to like a 1.0 housing? sorry if these are dumb questions, we are in a low elevation area!

I would call MPD as they are the guys whom deal the most with the singles or talk with one of them on here.

I would go with both of the tighter housings to keep spool time down.

My wife's had a 475 .90 87 turbine, 110hp(whatever that equates to in %) it ran fine and could be driven smokeless. However, it had to have the fuel laid to it down low and would fog an intersection for 2 seconds, then take off. Boost really came on about 1700ish.

It won't fully clean up 100% I don't think but you will get a good bump in power.

I would go 87/81 w/ .90
