Reversion can me measured with mass air flow. When the cams switch you should see the voltage jump. If it doesn't, it is likely poor scavenging caused by reversion. Reversion will cause detonation ...
Gio, i retract my statement on the gutted car. Must be a lot lighter than mine, i can't keep a transmission together lol. I went through 4 transmissions last season trapping 122-124mph. They were a...
The larger trim of my turbine will offset the increase of backpressure from the higher pressure ratios i have to push to make boost. Vadim has a lower trim turbine, that is more restrictive. So it ...
when i datalogged the ex only cam switch, the maf voltage dropped noticeably so i didn't bother to dyno just the exhaust cam. By dyno results were based on JWT's suggestions back when i did that te...
you can not dial out overlap on the VE cams effectively without causing other issues. By taking out too much overlap on high cams, you produce a negative overlap on the low cams. This causes it to ...
I would say if you don't feel it, don't bother switching it. I ran my car to redline daily for a while because i didn't see the point in having the cams switch. It seemed pointless because i didn't...
Yeah, the ramp angles on the stock cams seem to provoke float pretty early. 7500rpm is the most I would take it and be wary of bouncing the rev limiter really hard. You have a soft limiter and that...
You will need GT2871r for that output. T3 will be easier to make that kind of power. GT3071r will do it on 18-22psi. The GT3076r will do it with 16-18psi. But of course it depends on your setup.
Torque to yield require angle torquing. 61-69lbft doesn't sound torque to yield to me. Head bolts are TTY and require several steps in the FSM to torque properly, on top of using specified angles d...
the larger cams will work fine with a large turbo. A guy local made over 600whp on 16psi with a GT42r with a big housing and N1 cams. It was being tuned for E85, but he never got it fully tuned.
My only concern with the timing is that reversion is more present at higher rpm when exhaust backpressure is highest. Lots of timing with lots of heat can cause issues. I experienced detonation at ...
Nice. Yah, I have tried turning the timing up more and more. The engine just wants to keep making power up until I push over 19* base. Then I start to get some light det on the plugs.
I'm not really against the log manifold with the VVL. But you do get much better results with something else. I bet a GTiR mani with a GT2871r would perform better honestly.
