Let me grab my popcorn.

Too much torque. :cool:

1.5 bar is ok - as long as you have the fuel to support it.

Did you have injectors?

Its not my motor its a customer, It has 1100cc injectors.

Ouch! That's hard to look at.

wow!in what condition that motor blew?top speed run?aggressive timing?well i guess im lucky i didn't throw a rod with my 2 bar a28 setup!

I met a local guy running the same thing, upgraded k16's meth and 22lbs, he said its fine, He did have upgraded fuel and upgraded ICs.

What was the full setup and the subject car in this post?

I too would like more info on this! I run 1.5bar on Gt2871r's and stock engine... A lot of the mid range torque is tuned out, but I still make 1.5bar above 4500rpm!

Yikes that is some good carnage there. Any more info on the cause of the snap? I am leaning towards way too much torque, way too early in the curve. Definitely not the norm to display the strength of these engines, few have pushed the stock engine past 800-900whp (997.1 896whp stock engine and PowellsBeast). But just as any platform, if not all is playing nicely together in a setup (fuel, turbos, intercoolers, stock ECU/Standalone, etc), it doesn't matter what you have, built or stock engine it will go. Definitely sad to see though.

We believe the car was running 1.7 bar previous to this customer buying it, he changed injectors and ECU to a syvecs. The previous customer may have used even higher boost than 1.7 bar to achieve a claimed 60-130 of 5.8 secs and this no doubt is where the original damage of a bent rod occurred, for some reason the customer was revving this car hard outside a fish and chip shop here and the motor let go while revving in neutral.

When the car was first purchased I V boxed it and the performance was WAY down on what was advertised so the customer fitted a Syvecs and larger injectors so he could run ethanol or meth, car measured 630 hp on a hub dyno when it was mapped !!!

More than 800 NM aint good for the stock engine and the transmission.

Some guys still don't get it. Meth on pump gas and lots of boost is a no go. If you can't afford race gas don't buy a P car. Otherwise turn down the boost. That simple.

I agree. I want to run higher boost but will only do it with race gas.

And just because one has a stand alone it doesn't mean the motor is miraculously fail proof. On the contrary, I'm guessing various knock sensing maps are moved out of the way etc. Just my opinion.

You're kidding me.... Revved it outside a fish and chip shop?????? hilarioushilarioushilarioushilarioushilarioushilar ious

Have you looked at the knock sensing and control on a Syvecs Mark? I believe its far superior to a DME and this was tuned by the guy who tunes syvecs on some of the fastest cars in the world, I may be wrong but I think the fastest R35 runs a Syvecs and was tuned by the same guy.

Whats wrong with Meth and pump fuel Mark? Surely if its only tuned to the point of being safe with no knock then whats the problem? After all there are many diff race fuels! If its tuned for 109 you could say why not tune for 118! the point is the extra HP you can get adding meth to pump fuel is good value for money, now the problem here is not DET (the pistons are perfect) but too much low down torque so the solution is to build a motor tom take that torque not detune the car !!!!

I'm not questioning the tuner at all. my point is : how many stock motor cars do you hear of blowing up when they run race gas .... And how many cars do you hear blowing up on pimp and meth?
That's all Im saying. Problem is when you tune on meth and pump as if it's octane replacement that's where things go bad. I know of 4 cars in last few months with such set ups- pump and meth and kaboom. That's all Im saying. It just seems to happen a lot more often then on good gas. THats all

Wow just wow that sucks I'm tuned at 1.25bars to 1.3bars on pump and race fuel I'm at 1.4 bars. Going past that like marski said the rods just can't handle that power. To my lowered my torque low end so I don't blow my motor. 1.5 bars is to much for that motor. Just my opnion.

Thats interesting Mark how did the others blow up? I can see the point completely if it DET related and no doubt that on 118 more power could be had but in this case it looks like just a fact of too much low down power on stock rods and hi mileage motor (100K) personally I think the meth is a cheap way of grabbing a few extra ponies as its no more to buy here than gas !!!! BTW the boost was not increased when running the meth, I presume just more timing added
The knock control on the Syvecs is massively quick and pulls timing from each individual cylinder if it detects it and if it detects a massive amount will go into limp mode. As you prob know with a fuel flex sensor and after being tuned for a 20% meth mix the syvecs then automatically throws in a tune for whatever % of meth it detects in the tank so there was no user error in this case.

The point of the post was 2 fold to illustrate that too much low down torque will kill our 'bulletproof' motors and 2 its not a good idea to rev the tits out of them in neutral !!!! How long it would have gone on for without the rev is anyones guess.

True!
The stock rods can handle torque up to 850 NM. Thats easily achieved. So cutting low and mid range torque is a wise thing to do. Thats why u cannot get more HP out of a stock engine than around 630 HP. Even for that u need different injectors, turbos and fuel pump, besides a good tune and low lambda around 0,84.
