Hi people,

In a very simplistic, everything else upto tasktic way, would a pair of 2871s part no.707160-10 be able to hit the 800hp or more?
greetings,

joe

the garrett gt2871s are rated to 400 bhp each. from what ive read on here with twin turbo set ups on rbs seems like they loose around 10 % so would mean these top out at a theoretical 720 bhp on a rb26dett.

Im running these turbos(ported housings and manis) now on a 2.7 stroker miner headwork and stage 1 cams , car still waiting on being mapped .
Tuner told me to expect anything from 670 -700hp with my set up !!!!!!!

im thinking of trying this set up on my car. currently running a turbonetics t76, with some very aggressive cams, thinking of going down to twins for a bit of stealth...
let me know how the setup goes when tuned :D

im making 550awhp on -10s (i.e. 610rwhp)

what does this equate to in bhp figures? what % is lost in driveline?
i think im @ 700bhp!?

this is with a ported head & big cams, only on 23psi though

thanks for the confirmation, my tuner advised i could achieve 500rwkw if i ran e85 which is a pump fuel here in aust but is limited, ron level is above 100. do u guys have access to e85 in uk/europe?

btw, im running pump 98

you'll need to get alcohol-proof fuel lines and maybe fuel pump as well to run E85. In the States, "flex-fuel" cars modified to run E85...just some fuel system changes and I believe a different ECU map.
