they seem to be less expensive (even with the accessories) than vortech/procharger and keep the oil cool. this is their largest 38R from what i understand, so a bit bigger than v1 ti (0.5 kg/s = 860 cfm)? they are using a separate oil system incl. filter, cooler, (reservoir?) and hoses. i wonder where it all would go in vette.

the rotrex is very compact in size, plenty of room.
I don't think there is a kit but where there is a will there is a way. They are very popular with the BMW and euro crowd and seem to be a good product
they for sure have enough flow now to use one blower. Not sure why you want to blaze a trail but go for it!!
I've tuned one of these Rotrex blowers on a LS1-based engine. I don't know which version it was, but I think it was targeted for 5.7 liter engine, i.e. LS1.
Boost was somewhere around .5 bar if I remember correctly. That was with LS9 cam in this LS1. Some kind of short runner aluminum tunnel ram in the engine as well.
If it was me, I wouldn't probably selected that one, at least for Vette.
What horsepower and torque did it generate after you tuned it?
Sorry, I really don't remember exactly anymore. It was somewhere around typical A&A kit I think, but that of course depends on other mods, so very difficult to compare.
The original engine builder did not put the engine in a dyno and sold the engine to a customer and then it came to me for tuning when the car was in classic Camaro.
I think both boost as well as rwhp were lower than expected. Also, max rpm from that blower was near maximum or so. However, customer said he really doesn't need any more hp and was happy how the engine performed.
