Hey guys,

I purchased a FIS turbo to replace my VS 7875. Im hoping to gain spool on the footbrake and possibly get into the 5's. Being a better turbo I hope that itll peak higher than the 7875.

Heres the setup.

3600LB 1980 Buick Regal
SBE 5.3L ARP studs, turbo cam, etc
cast VS Racing 7875 1.25AR
4L80E 3400 single disk
Holley Terminator Xmax
Flex Fuel (usually run e40-i mix it myself)
Footbrake (builds 4psi @ 2700rpm)
1.63 - 60'
6.56 - 1/8th mile (18psi)
110mph

I hate to ask here on a forum but i cannot find any data or dyno videos etc of an FIS ETR S478/83 V5 cover, 1.10ar or any comparable setup.

Anyone got crank HP numbers, Wheel HP numbers, 1/8th or 1/4 mile MPH trap speeds (weight included)?

I would call or email Jose at FIS but id rather not (he probably is already flooded with people asking questions).

Thanks in advance !
