yup. controlled boost is a wonderful thing. Maybe someone who knows what they're doing (ie. not me) can throw me up in that graph.

Nice job Johnny boy! Good to see it up and running.

WOW I just PM Deerhunter on M-net about his 3071R stroker. His response was a link on a discussion here.
Deerhunter "I'm at approximately 2,000 ft above sea level. The difference in spool is very apparent compared to Grand Junction (4,500 ft+). I'll do a datalog as soon as possible, but here is my recollection (based on gauge pressure): 5 psi at a tick past 2K 10 psi before 3K 20+ psi before 4K Seat of the pants feel is VERY nice I wonder what it'll do at sea level? BTW, I'm using a DEFI boost gauge, so I'm going to assume that it's fairly accurate. __________________ '93 L.E. (Mazdaspeed Alternative) 2.0 litre with FMII (GT3071R); Hydramist; Quaife gearbox; AFCO's 355 HP uncorr. at 19 psi; 420 corrected at 23 psi " He said he would data log later but he is on vacation. Looking at that it is IMPRESSIVE. I want, I want, I want |

Did a pull while on my last road trip in FL. Swapped out the cheap-o turbo style eBay Raptor muffler for the big magnaflow 12578 = nice change.

Trans & Rear End Ratio: 5-speed, 4.1 LSD Rear tire size: 225-50-15's Trying to figure out what spring is in my wastegate, looks like about 14psig(from this datalog), it was supposed to be 8.7. Need to tune the boost control with this new found data. 18psi is about right but the ebc is set to start around 8psi so with the just spring pressure it's cracking early. Apparently not enough duty on the boost solenoid either, 4psi spike. kpa (psig) RPM 37.57 2082 50.14 2125 90.61 2144 100.12 (0) 2335 105.64 2460 110.24 2593 120.36 2796 130.17 3019 145.20 3296 160.22 (8.5) 3589 181.69 3792 200.08 (14.5) 3929 230.14 (18.5) 4207 |
