Rx7.com gets about 700 RWHP with two rotors. so with another one it could be safe to say 800@20 psi. PF gets like 500rwhp and they only go to 12 psi, w. their 3 rotors.

ari's car dosnt make 700 try around 600 at the most, call and ask, and i think that is with NOS if i remember correctly. with a 20b and a t-88 your looking at around 800-1000hp depending on how much boost, and PFS's 20b makes 500hp with the stock turbo set up not a t-88 big differance.

705rwhp on nos at 30psi, but after the dyno run the motor let go.That's maximum,usually he produces more than 649rwhp.Graig, you should now better that numbers don't remain the same.

what about lag? would the lag be the same as with a 13B? or would the 20B have less lag then the 13B?

On my 3-rotor ( www.hitamn.hm/rx7.htm ) I ran a 60-1///P-trim 1.30 , and it would pull 21psi boost by 2500rpm, and was on power by 2800rpm. I am now switching to a Garrett TA45 which has a compressor section similar to the T88, but with a turbine section that dwarfs it, and I am expecting it to be on power by around 3500rpm.
Power before the TA45 I cannot quote, other than it getting 130rwKW on a Dyno Dynamics at only 3000rpm and 4psi boost (held about 15% throttle). This was done during the initial fire up of the fresh engine to get a tune good enough to run the motor in. It equates to around 210rwhp on a dynojet.
After run-in, the 60-1 comp was holding it back about 5500rpm where the power would fall flat. With a 60-1 limited to around 600 to 650 flywheel HP, I would say the motor was hitting about that limit. I think the T88 would ge a good street turbo to use on a 20B, but to get any serious power the turbine wheel would need to be a little higher in flow capability, and so to the housing.
With 50% more exhaust energy, quite a high flowing turbo is required as I found out.
For all you guys that think your 13B goes pretty hard, you need to experience a well sorted 20B to see what the difference is. Less lag, much more torque, and brutal acceleration in any gear you pick.
