Hi people,

I tried searching for the -5 Vs -10 thread however I could not find it, this topic may be a little different as the car is running on e85.

Key considerations

- Motor is a fully built Rb 26 (26 bottom end)

- 262 in/ex cams

- Car is built for street/drag

- The car made 420 rwkws on 20 psi, we tried raising the boost however there was no power gain (I believe turbo’s were out of puff)

- Fuel system is more than capable of 500+ kws

My questions are

1. How much laggier would -10s be compared to -5s (running e85 can put more timing into it)

2. Is there an in-between turbo or any other turbo suggestions that will get me up to 500rwks?? (please keep in mind that this is a street car and needs to be low mounts)

Attached is my current dyno graph

Thanks

Daz

There you go.

Quick answer. If it's a 2.6 don't bother. It will become a nugget.

Gav made 460 + on the baby -5's. It's just a matter of setup.

Question answered, close thread ;)

For a twin set up chasing that power I wouldn't use -10s, it will just be a laggy peice of crap.. Especially on 2.6.

You probs won't make 500 on -5s but It's probs your best option if you wanna make big power on twin low mounts..

Unless you wanna run a pair of the new GTX turbos.. You should do that :)

Dan, what's involved in being the test dummy?

Someone is already interested in trying them but I could ask for a second pair maybe. Still waiting for info back to confirm the comp cover is going to fit against the standard manifold

    • Take the value it measured as, and pick the closest range available that is above the reading on the screen.   Also, no point just testing the coils. Read what has been said again. You need to test all your wiring, everything.
    • Does the scanner do all the CUs in the car, or only the ECU?
    • @666DAN sorry to bring you and old thread.     I've got my de+t done and it's all running great other than 1 small issue.    Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd when selected . But nothing when in  drive or what gear your in when you pop it into tiptronic. I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Do ya have any ideas?     Cheers man
    • Well I recently changed my rear axles and was thinking if I bumped anything, I have been driving the car for a while now though... But it has been raining today so everything is wet under the wheel arches. Brakes feel fine and can't hear any of the metal screamers, I had a squeak coming from one of the handbrake drums but that seems to have gone away a while ago. I was going down a hill when it lit up and I did feel the abs bite for a second and question why it did it?
    • Correct. Um. I dunno. I haven't cared enough about the way that the NA cars work to know for sure. But..... The 33/34 turbo manual cars have an electronic speed sensor in the gearbox that outputs a +/- (ie, sawtooth AC) voltage signal. That is connected to the speedo. The speedo then outputs a 0-5v square wave (ie, PWM) signal that the ECU (and any other CU on the bus) sees. The speed sensor is NOT directly connected to the ECU. So here's the problem. Your new ECU expects to see the PWM signal, but must somehow be getting a direct signal from the diff speed sensor. Which would suggest that the wiring of the NA car is not the same as the turbo cars. I think you will need to spend some time with (hopefully the wiring diagram for the car) and a multimeter to see what is connected to what. Then, presuming I am correct**, you would then want to separate the ECU speed signal input from the rest of the car's wiring, and probably either buy a speed signal converter, or build one using an arduino (or similar). That would take in the speed sensor signal and output a scaled (and suitably rearranged) signal for the ECU. ** We shouldn't presume that I am correct here, because there might be something else crazy going on. I don't think you could convert the speedo to be fed from the gearbox sensor, because the pulse rate from that sensor is probably different to the diff sensor and then the speedo would read wrongly. And this also wouldn't fix the ECU's problem either, because the ECU doesn't want to see the gearbox signal direct either (assuming that they are all on the same wiring, for some odd NA related reason, see above caveat!) Does this help? Probably not. Can you make it work? Almost certainly. With the above work. You should buy a handheld oscilloscope from Aliexpress so that you can view these signals directly. Connect up the probes and drive the car. Show photos of the screen when drving at known speeds and connected to different places, and we'll see what we can learn about it.
