thanks every1 so far with comments, ive been really interested in either the t51r bb Kai or SPL, or t88....single setup tho, but i wouldnt mind keeping the twin setup :), i want to make big hp so keep them coming guys.., i wouldnt mind looking at the twin setup that TiTan come up with "Veilside R32 drag car runs twin GT3582R's"

everything is costly so i might as well go best then cheap!!!

thanks guys

sory to hijack

just on this topic im looking for a turbo a bit bigger than a 3582R but dont want to loose too much response due to car being used for drift.

have a rb30/26, forged pistons, rods, cams, high mount mani, greddy plenum, 100cc injectors and all the usual bits and pieces.

should i just go the bigger rear housing (1.06) or what is the next size turbo up?

cheers

rockabilly - whats with the big midrange dip? Your loosing massive mid-range poke from 4700-5800

The line should continue building, and not drop off and resurge

Oh, and if anyone needs a T88 (saw it mentioned earlier) i know of a kit for sale. PM me if interested

      Theoretical Power Numbers

      Yeah, so I think that is the point. If you presume a 25% lower reading on a chassis dyno than what the engine is making, then the most you would see from a 720HP engine is ~550wHP. "Lose" a little more because AWD dyno and the number will be lower. Call a hub dyno "wheel HP" and you should see higher numbers. But the horses would be a different size. And as Murray says above - an imposed 90% DC limit drops 550 down to 500 straight away. 80% takes you down to ~450.

      Sounds reasonable to me.  Do you know what your injector duty cycle is? I guess everyone has their own personal limit as to how high they want to flirt with 100% duty cycle, but who knows what your tuners limit is. Maybe they like to cap it at 80%? Now your injector CC to HP conversion has a 20% hair cut on it, then through drivetrain losses, yeah 500rwhp seems ok to me.  If you plan to spend on your GTR, modern injectors and a modern ECU will go a long way!

      @GTSBoythanks for replying. That's realistic and I always believed in the injector-hp rule of thumb. I am however making way less than that 😕 My guestimate/goal for the setup is a reliable 500rwhp, R33 gtr, seems realistic enough doesn't it?

      720cc injectors can only support about 720 engine HP. Maybe a little bit more. 600rwHP is, um, a plenty big chunk of that number. Probably running to the top of your fuel supply.

      Hi gents, sincerely asking you guys the theoretical or actual power figures expected from the setup below: HKS Y pipes & 80mm cat back, Sard (denso) 720cc injectors, DW300 pump, R35 MAFs, Twin HKS 2530's (stock headers), Trust intercooler, stock BOV, stock intake plenum & TB's, N1 oil pump, MLS head gasket, forged pistons, poncam B's, Power FC, pump RON97, nismo coppermix twin plate, 18's on 265 rubber. So I've pretty much listed all that matters with regards to making and putting the power down. Asking as I may or may not be getting the full potential of my setup (bottom end was running 600rwhp on a different car). I have done numerous Dyno sessions with slightly different setups but more or less the same outcome which leads me to conclude (reluctantly) the setup is maxed out. Will share graphs but would like you to share your input first for better effect. Thanks in advance, guys!
