On your car, what is the maximum HP are you able to achieve without modifying the internal of the engine ?

Mihnea I know you will read this

 

No established number that Iam aware of. It really depends how long you want it to last...

 

This is almost a "what oil" question.

As stated above, there is NO number- you will get 20 replies with varying anecdotes of 'what I did' or 'this motor blew'... it is all a matter of risk:

The entire production output of all motors has an inherent variability in their strengths. At stock power levels, 99.9% of the motors will go 100k miles.

At 50hp more hp, 99.5% (perhaps) will go 100k

At 100HP more, 98.5%

At 300HP more.... 30%



The numbers above are for illustration only- the point is you will never know WHICH engine you have...is it a lucky/strong one or not. Or did that guy that blew his motor at 600 have an unlucky/weak one? Or did his tune not react in time to something....

All a matter of relative risks...

without detonation 1,4 bar boost is enough for stock internals......imho (what ever hp this will be.....)

 

To do 5,85 60 to 130 , your car must produce a lot of HP, did you modified anything internaly ?

 

1,4 boost that a lot of boost

 

yes but without detonation don`t lean out of fuel for my understanding it should be possible

It depends on your tuners flash, fuel, turbos, IAT,Dutycyle of injectors,backpressure, track, street and some magic.....

 

Depends on how you look at it... some run more timing with less boost some less timing with more boost...

to run 5s it takes more then just HP...

 

why do people in the usa quote numbers in bar? we use psi, no ?

 

450hp @ the crank.

 

I dont know how much hp it makes. It has never been dynoed. Nothing has been internally modified. I have run this power level for about 6K miles. The car has 41K on the clock. It may blow up tomorrow. There are no guarantees. Iam not planning on pushing any higher than Iam currently. But there are many who safely have done so.

 

so if i will run an simple tune ( ecu + exhaust ) my engine will be "dead" in 100k km or 160k km ?!

 

Who's tune? UMW or Upsolute?

 

no one from this, it will be an german company named SKN, next week we will put the exhaust and the ecu modification

 

My point being a "tune" is not 'just a tune'...UMW is perhaps one of the more conservative approaches, whereas Upsolute has some spotty history with regard to their approach.

SKN? Hardly ever heard of them in this community (6speed), you might be one of the only ones going way back. But then again we are rather Amero-centric here. Still, I'd want to know THEY know what they are doing. (and unfortunately, anyone that knows just a bit more than you can look like an expert...)
