Obviously the pulls were SAE corrected, but it was a nice 65* morning. My ECMLink software predicted 384 w.h.p. and 390 w.h.p. a week earlier on an identical tune. The AMS dyno recorded a 3-way average of 384.3 w.h.p. So what I've been saying for years that DSMLink's h.p. calculator is as good as any dyno, and extremely close to a dynojet readout. The relevant mods are: EVO3 16g (minor porting to remove exhaust ring step), shimmed wastegate actuator, HKS EVC boost controller, FP race exhaust manifold, 2g ported 02 housing, 2.5" downpipe/testpipe, 3" thermal catback with 2.25" neckdown, 660cc fuel inj., Denso 150 Lph fuel pump rewired, HKS 264 cams, EVO3 ported intake manifold, 63mm 1g t-body, FP 4" compressor intake pipe, 2" j-pipe, 23"x10"x3" extruded core FMIC w/2.5" short run tubing, phenolic intake spacer kit, ECMLink V3 on stock 2g MAF, ARP 11mm headstuds, etc. Stock head, stock motor. Basically the setup other than the boost being turned up and high octane fuel is my street setup. No funky dropping of the downpipe or pulling the airfilter off or jacking the timing up to insane levels. The tune was basically set at about 12.3-12.7:1 A/F ratio and peak timing was 21* above 6000 rpms. Boost was 30 psi more or less in the midrange, dropping to about 20-21 psi at 7000 rpms. I didn't capture an ECMLink datalog but the car is dead consistent and the last street pull I made on high octane the car was seeing about 40 lb/min at 6000 rpms, 41 lb/min at 7000 rpms. Fuel was 5 gallons of 93 octane, 5 gallons of 118 octane Xylene, and 2 bottles of Lucas race octane booster. I'd have liked to crack 400 w.h.p., but given the mods I had it wasn't going to happen and I kind of expected that. My goal is 460 w.h.p. and I think its possible with alot of work and the mods listed below. My strategy is a little different then most guys. I personally don't care about big midrange numbers, only my power peak. This means for the most part I can leave the sub 5500 rpm tune pretty conservative. It also means I don't need huge boost to do it, simply "holding" as much boost to redline is sufficient to pull a good number. Future mods to achieve that goal: 1) Clock 16g compressor cover, weld 2.5" outlet elbow and port compressor inlet and outlet. Also eliminate 2" j-pipe. 2) 2.5" recirculated external wastegated 02 housing 3) Tial 38mm external wastegate 4) Speed density via ECMLink and eliminate 2g MAF 5) Install Beehive springs and Kelford 272 cams with cam gears 6) 3" downpipe and cutoff 2.25" neckdown on catback 7) E85 conversion with fuel pressure regulator, 255 walbro fuel pump, 1150 cc fuel injectors. 8) Bump high rpm timing up from 21* to 23*.
