I've done a ton of searching on here and haven't really found too many people posting their results with the VSR 7875. Was looking for people to chime in with their track results/Dyno/street encounters
From mild 500rwhp set ups to maxing this thing out
Yeah with the glide and being light I don't see why we can't hit our goals
Space was the limiting factor and I haven't seen any VSR 7875s go 150 yet, It may take a built 5.3 but were gonna try on the stock style parts first we got 10mph to make up
I made 705/746 through a cammed 5.3 at 16lbs and 19* but with T7575. This was also through a 6 speed. Would think the two turbos are very similar in flow numbers.
i'm really interested. based on the weight difference we are probably making similar power on a maxed out 7668 and 93 octane. mine has gone 6.5 @ 111 with the 4l80 and should go around 10.0 @ 138 @ 3600# (previous best with the manual was 6.7 @ 107 and 10.3 @ 136)
I dont see me doing much quarter mile but i'd like to approach a 6.0 @ 115 and break 145 mph if i ran it all the way out. it would be nice to get this turbo vs the huron speed one and save $150
be carefull pushing those turbos on 93 at the levels you are pushing they are pumping a ton of heat.
my buddys Camaro has ran 6.05 at 114 and 9.44 at 141 mph on a cast on3 78/75 @3550 lbs E85 . engine is a 5.3 with isky triple 12 cam 400th and 3.73 gear with 31 by 13 slicks. we were noticing it getting iat pretty high at 20 psi boost around 175* so we swapped to his billit borg 80/83 t4 and no track runs yet but street testing has seen the iats under 150* and that's heat soaked without a cool down.
I think the .96 housing is the limiting factor with all the 78/75 turbos. but for the money they cant be beat. good luck.
Honestly if you're trapping 111 at 3600 you're make a ton more than me that's about a 800 pound difference with only 1 mph
That On 93??
yeah, however, on that pass i lost a fuel pump on the launch and was running lean enough to melt a cylinder head on the big end. car was probably making a little more power than my normal tune
