1M Time Attack Car

Ad, thats KAK!!!!

...would you be interested in borrowing my mother in laws broom for 2 weeks?? :mmm:

I will slap you with that broom!!!:fencelook:

Those snails fail on brand new cars more often than you think. On my first 335 both failed after 10 000Ks. Started with wastegate rattling then the snails said goodbuy.

Heavy boost, track use can also lead to premature failure. Just a matter of time. :thumbs:

I like that heavy BOOST thing ALOT!:thumbs:

 

[outlaw335]

Ed how much boost were you pushing with e95? Also was there any signs that your snails were going like smoke or did they just give way?

 

[Twinz]

Max boost on the stock snails in my case is 20psi. Have not attempted to go above that. Not found a reason too. Driving on map 5, meets my daily requirements.

Heavy whinning sound like at very high boost on bigger type turbos and then every now and again i noticed some smoke once i stopped at a robot but main thing was the boost was irratic and only started a couple of days ago. No damage to motor as its still early stages of wear on the turbo but rather be safe and park it than be sorry later.
Stock turbos cant handle/maintain anything near to 20psi, you might run them up and spike them to 20psi but they fall off at 4500rpm like a lead weight.

On our Data logging we found they battle to do 20psi and you really have to map carefully and use the right fuels. They were not made to handle anything over 15psi reliably for 500000kms. Was fun though!

Yeah it was always the plan with my wagon although we not ready yet for the big Turbo setup as the turbo is not here yet so we will settle for some new ones for the time being.

 

[moranor@axis]

did you log EGT on the old setup? im thinking maybe it might be worth it to run i higher water mix to try cool the turbos so they last a little longer...

 

[ed_z]

Water meth is injected on the intake throttle body side direct into the motor to bring IAT's down.

 

[moranor@axis]

I know water injection is used to keep EGT down on diesels im just not sure it will work the same on a petrol but its worth looking at...

 

[ed_z]

Water hitting a turbine spinning at 100000rpm???

 

[moranor@axis]

by the time its Through the combustion chamber its already steam no way that will damage the turbine the water is very fine by then...

there are even guys that inject before the compressor turbine without added wear... there trick there is to not inject too close to the turbo so the droplets have time to disperse... the effect of injecting pre turbo also changes the compressor map allowing it to operate like a slightly larger turbo... im not suggesting this though because there is some risk and problems involved injecting pre-turbo...

what i would do in your case is experiment with different mixes of W/M and see if a higher water content will bring down your EGT you have the equipment you may as well try

 

[Twinz]

A 50/50 water/meth mix should help to hold temps in check but the supporting mods must be in place as well. Free flow exhaust with no cats and little or zero back pressure; IC; Bigger oil cooler; good afterrmarket intake; less restrictive chargepiping etc...

We messed around with pre-turbo injection about 10 years ago. Works very well. Need a super atomising jet so the mist atomises long before it reaches the turbo's but the modern turbo blades are more resilient anyway.

yip but there has been blade tip erosion in some cases... another problem that sometimes happens is pooling in the intercooler... other than that it like getting a slightly bigger turbo for very little money :rollsmile:

R150K motor per injection vs gain no thank you!

 

[moranor@axis]

thats a bit like saying N2O or upping boost WILL kill your engine... setup is key...

if you making an engine reliant on it you run some risk because if it stops working then you got trouble... but if you just using it to make an already stable engine perform better there is no risk...

obviously like any modification there is risk involved, but plenty people are making good power off W/M without any problems...

 

[Twinz]

The X35 platform is already making big power with w/m injection into the charge-pipe. There is no need to change this successful modification. We extracting even more power with e85, bigger turbos, nitrous and supporting mods such as engine piping. :thumbs:

 

[ed_z]

Not sure what all the fuss is about, I have water meth I have it mixed 50/50 which by the way is the safest and stronger of the mixes which once again i have tested on my wagon and I have done a lot of testing proving it on the dyno with very high HP figures by means of charge pipe injection. Fact is stock turbos are exactly that not made to run higher boost levels. Over engineering seems like the order of the day here.

If meth charge pipe injection stops working system reverts back to stock map and has high speed solenoids and flow scaling for protection when any issues of atomization or less flow volume detected. And no it's not saying that all of the above u mentioned are more reliable safer power and yes putting more wear and tear but compared to very unreliable type of power of pre injection in terms of safety I don't agree at all!

If so successful tell me Sherwin how many of the cars you tune have this pre turbo injection system running?

Car runs perfect on 50/50 meth and logs prove it!

 

[moranor@axis]

look all im saying is you may be able to bring down your EGT and make the turbos last a bit longer by using more water in your mix and it will not damage your turbine wheel... if you dont want to try it its your prerogative... If you do try it i would in interested in the results...

Dont really see any point in arguing about it...

 

[ed_z]

It does not work adding more of any of the 2 fluids?

I don't think pre-turbo injection is ever going to break the engine. Maybe corrode the blades of the turbo, but not the engine.

Yeah at sea-level. Up here the turbos are running off the compressor maps.

If so successful tell me Sherwin how many of the cars you tune have this pre turbo injection system running?

If you read my post I said it was successful like 10 years ago on the vehicles we tried then. To answer your question the answer is zero for now.
