My RX-7 on the dyno - 371RWHP
Rushed and got my '88 10th Anniversary RX-7 back together. We had changed a bunch of things on the car, including adding a standalone, wide band, elec. boost controller, new WG spring, etc etc. All this in a rush to get to our dyno day on Nov. 11.
Quick low-down: Stock unopened Series5 (GTX) motor Microtech LT-8s standalone ECU PLX M-300 Wideband with O2 installed in mid-pipe Turbo has a 60-1 compressor wheel, P trim turbine wheel, in a T04B front cover with a 0.86 A/R rear housing HKS T04 undivided manifold TIAL 35mm WG w/ 12 PSI spring (open dump) HKS EVC EZ Boost Controller Custom 3" downpipe/midpipe with Apexi GT Spec catback 100% stock ignition save for the Magnacore plug wires BUR9EQ spark plugs FD3S Alternator Stock fuel lines/rails 720cc x 4 fuel injectors Walmart 255HP Fuel pump 93 octane pump gas Dyno Graphs here: http://www.namike.com/albums/album15/mike330rwhp.jpg http://www.namike.com/albums/album15/mike358rwhp.jpg http://www.namike.com/albums/album15/mike371rwhp.jpg 14 PSI, 17 PSI LOW timing, 17 PSI decent timing Still only running 7 degrees of advance at max boost :( We had a brain fart on the dyno in regards to our base timing numbers. Car pulls 20" of vacuum @ idle and runs great! Questions/Comments? --Mike |
That is with the high comp 9.7:1 rotors, correct?
Great results on a stock engine, congrats. What octane were you using? |
"Walmart 255HP Fuel pump" Gotta get me one :D
|
wow glad to hear your car running so well .... i'm veilside from teamfc3s.org.....
would like to know who did your tuning?... and where u bought the turbo from and how much.... sigh im still in the midst of setting up my car etc... such a bummer...... was the microtech install easy? |
RX: Stock 9.0:1 compression. Fuel was 93 octane pump gas
Carl: :-) FC: Myself and my buddy Dan (BlackFC on TeamFC3S) did all the tuning ourselves. I bought the car basically as is, except it had a bunch of piggy backs I ripped out and did the car right with the standalone, wideband, etc. etc. MT was simple to install, my car cranked up the first try, and actually drove all the way to the dyno (60 miles) on the stock microtech map. |
Nice numbers on a 60-1 HiFi(?) considering the timing! Wouldn't you be running out of fuel right at around your power output? It sounds like your 371rwhp run had your injectors flowing damn near 100% duty cycle!
|
Mike you said 0.86 turbine housing... you sure you don't mean 0.96?
|
It's either 0.84 or 0.86. Small little guy. IIRC, I think it's even an divided housing on a non-divided manifold. I am not 100% sure on that. Yes, the turbo is a 60-1 "HI-FI". 3" compressor inlet and 2" compressor outlet.
Yes, I started to max my injectors out, so I raised my static fuel pressure to compensate. The Walbro kept up, and that did the trick. --Mike |
ah... nice... i do hope u can share your tuning tips with the rest of the group buy members as a lot of us dont know where are we goin....
=( im goin to use a tech-edge wideband..... p/s: are u using pre-mix? and did u take pix while installing the microtech ? |
FC: Yes, the car is running a 100:1 ratio of premix. The Tech Edge wideband works well, especially since it has the NTK sensor that you can mount closer to the turbo. My LSU sensor that I have is working well, but I have it mounted in the midpipe to keep it as far away from the high EGT's of the exhaust. It hasn't given me any issues. There are tons of threads on these forums about tuning. Watch your A/F ratios and don't get crazy with the timing. Rotaries don't need a lot of timing to make good power.
--Mike |
Nice work, Mike. Get that static pressure raised up to 55psi and then break 400's with it. Add some more advance to the leading and skinny up the trail-split timing to about 8-10 degree split. Nice job!!

Damn i'm Jealous. I have a bigger hotside, and what i feel is a great street port. I'm looking forward to similar numbers. Post some pics with the big thumbs up! You deserve it.
|
BTW: I am putting the car up for sale. $7500 and drive home with 371RWHP, and a 10th Anniversary to boot.
More details to be posted in the Forsale/trade area. |
What's up with the dyno curves? Why doesn't the torque and HP curve cross at ~5252?
