Spiff Posted November 6, 2017 Report Share Posted November 6, 2017 Can't read the numbers. I've seen spinning tires before. You saying it isn't true? I'll post the print when I get it, I only have a screenshot of it right now. Nice Spiff! How did you adapt the SR20 CAS to the z24? I removed the cam gear from the sr20 cas axle and cut a offset notch at the bottom of the axle to match the oil pump shaft. Then I designed a new pedestal for it in fusion360 and had it 3d printed in nylon. https://www.instagram.com/p/BX2q2T3jRnR/?taken-by=sand_sjol Quote Link to comment

Would love to see the numbers for this. The vid doesn't show anything really just the car. I'm curious about what power is made at all the RPMs. Quote Link to comment
Lockleaf Posted November 6, 2017 Report Share Posted November 6, 2017 Very impressive gains compared to the turbodatsun.com build. Less displacement, only slightly more boost, much better power at that boost level. 1 Quote Link to comment

I'm curious about what power is made at all the RPMs. Probably misunderstood you then. Graph of the final run is coming as soon as I get the email. I have this photo I took of an earlier run though. A bit blurry but I believe it says 163.9 Power peaks just over 5000, very linear power delivery.

Less displacement, only slightly more boost, much better power at that boost level. Well, It's almost winter here so the cooler air definately helps, I believe his build was seeing some 70 degrees celsius intake temps and I'm at around 30-40 at max. Also I have the advantage of running tuneable efi I guess. What I can't understand is how that turbodatsun build haven't blown up? As far as I could see he didn't do anything other than retard the base timing to 0 degrees, that's like 20-25degrees all in? My engine was knocking like crazy even at 17degrees under boost and we had to pull so much timing in that area that we ended up actually loosing some hp compared to our initial runs...

datzenmike Posted November 6, 2017 Report Share Posted November 6, 2017 Odd graph. I assume blue= torque and red is HP? Torque is always less than HP above 5252 RPMs and higher torque below it. HP = TORQUE X RPM /5252 At 4000 it shows 225 torque which works out to 171 HP but it shows about 125 HP so the torque line is too high 1 Quote Link to comment
Lockleaf Posted November 7, 2017 Report Share Posted November 7, 2017 You're running coil packs correct? No longer the distributor? Quote Link to comment
Spiff Posted November 7, 2017 Report Share Posted November 7, 2017 Yeah I'm running Toyota yaris coils 1 Quote Link to comment

HP = TORQUE X RPM /5252 At 4000 it shows 225 torque which works out to 171 HP but it shows about 125 HP so the torque line is too high But torque is in Nm. If you convert to lb-ft and do the calculations it equates to 126. I assume that might be the issue? It tok some time though but I have the graphs now, so I'll post them as soon as I have it converted from pdf to jpg or something like that. Max hp was 168.4@5300rpm and max torque 230nm@4100rpm. This is at the wheels. Estimated 201hp and 274nm Quote Link to comment
datzenmike Posted November 21, 2017 Report Share Posted November 21, 2017 Ahh hah ...Nm, Of course. Never seen a dyno graph like it before. Quote Link to comment

distributorguy Posted December 4, 2017 Report Share Posted December 4, 2017 What altitude are you dyno'ing at? Quote Link to comment
nl320what Posted December 4, 2017 Report Share Posted December 4, 2017 Really nice flat torque band. Quote Link to comment
Spiff Posted December 4, 2017 Report Share Posted December 4, 2017 What altitude are you dyno'ing at? According to Wikipedia the nearest railway station is at 140meters above sea level Quote Link to comment
