Crower/carillo/pauter...if you genuinely want to make big power & still have peace of mind about a rod not exiting the block.

Pauter do custom size rods all the time unlike many other manufacturers.

just wondering peoples chose on conrods for an rb30 set to make 1000hp ?

Based on what?

The worlds most powerfull, quickest and fastest RB30 uses Argo so they must be plenty good enough I'd say.

Not getting involved with whats better or what not but one thing i like about the carrillos when side by side to other rods ive found the equivalent carrillos were consistantly lighter..... the downside is the price :)

ive used carrillo's in speedway moters that have done 30 race meets a season and they are throw away after that . they stretch and ya can kiss a motor goodbye if you dont pull ya motor down and measure them from time to time .

which exact model were you using? oh and engine type. We change valve springs on some v8 drag engines every few races and they are the best money can buy everything is relative to application.

Do the manufactures provde strength testing charts????? i'm guessing they don't. that would settle all reasoning.

there are plenty of independant test results around, if your really hardcore you could even send them to an AUSTRALIA NATA Accredited Laboratory for Mechanical stress Testing. I did such with a range of rods we bought out the back door of a big manufacturer that supplies a few jap and american brands. We sent the original and a "back door" special for testings to confirm they were indeed the same thing.

This said assembly line produced Scat, K1, Eagle, Brian Crower and a couple of other brands ran the same "assembly line". Some just do the finishing in house.

Argo etc are in a separate boat to the above 'assy line'.

From Carrillo;

“When considering any connecting rod, the configuration of the beam does not dictate the strength of the connecting rod. Different applications place different

requirements on a rod design, hence also suggesting different beam configurations. Deciding factors on which beam type to use include weight, clearance and actual load conditions in the engine.”

Very interesting. if they all published there results it would be clear which ones to buy. Generally i think they will all be of similar metalurgy which is why id be worried about lighter ones.

obviously in terms off higher RPM the thicker the cross section the higher the UTS but then as carrillo mention, other factors such as twisting could cause some issues which is why i think the I/H beam designed rods would be hard to beat???

    • 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.
