We have a lancer that was fitted with a t3/t4 a while back, he was making over 300whp....

But making 400whp stock would be hard on our cars.... We have weak piston rings... Though it maybe possible with a long powerband?... But I don't know when the valves will start fluttering.

Since
Horsepower = Torque * RPM / 5252

And we know our cars can make 250 torque no problem... Then rearranging with HP = 400, then RPM = 5252 * 400 / 250.... RPM = 8.4k

Just a thought.

 

The rings are not the weak link in there. The weak link would be the thickness of the ring lands on the pistons. And again it comes down to if you can keep detonation away. You will throw a rod before you crack a ring land.

That equation is valid only if you know what rpm the power is being made at. You cant figure out what rpm it will be at since you dont know the specifics of what the head flows and stuff like that.

For example, heres a miata engine making 400 hp at 5700 rpm and after that it starts going down. This will be the case with most engines that run a medium sized turbo. If you have a massively huge turbo then the power will keep going up and up and up right to redline and not decrease. However torque will decrease at somepoint.



As you can see from the pic you do not need to rev high in order to make the power. Revving really kills engines since every 1000 rpm you increase in engine speed the load put on the rods is Cubed.

Who is making the most power on the stock engine on this forum? Has anyone actually thrown a rod or cracked a ring land yet? The problem here is no one is pushing it.. Someone will eventually and find out the weak link on those engines and at what power it fails.

 

RRM is pretty much the go to company for lancer knowledge. If they say the limit is 9 PSI on a T-28, the limit is 9 PSI on a T-28, for a completely stock engine of course.

 

Whatever.

 

Feel free to do a search if you don't want to agree. Despite what you may think people have been turboing lancers long before you graced us with your presence and people have indeed pushed the limits and paid for it.

 

Who? Show me a picture of a thrown rod.

All Im trying to do is give people hope for turboing and explain that it is possible to make big hp numbers on a stock motor.

Believe what you want to believe. Jesus, am I going to have to buy one of these cars and turbo it just to prove my point?

 

What am I your damn secretary, find the pics yourself. You've been here since January, there have been turboed lancers since 2002. This is why there is the general rule of don't exceed 9 PSI on a stock motor., I think you might be able to push to 12 PSI but that's really walking on the knife's edge. Maybe you should learn more about this motor before you go about giving people false hopes. 400 hp on a stock motor isn't going to happen.

 

Is this guy trying to say the our motor can make 400 HP on stock internals? LMFAO! Wow, if only that was true. But like you said Franko, go ahead and buy a Lancer, and prove everyone on here thats been running these cars since 02 wrong. I'm sure you know better then they all do.

 

look he is noob, if he think he could do, let him be..
but i think everyone knows that 9psi stock is pretty much the limits on our car,
i heard if you can get perfect timing and fuel 12 psi is possible too much.. nah i think 9 is the safe side limit..

 

anyways muahaha watch me turbo my car very very very soon!!!
I think i might be the first person to use gt28 turbo in US

 

Good stuff man. I'm going to be looking into the real of 7-8 psi when I get back. But I'm going to start at 5 psi or so. Good luck on your build and keep us all posted.

 

Even with the arguing, this was a good read.

 

For sure. This thread had a lot of bull****...but, it was worth reading it to get the useful info out of it.

 

Franko........it seems you know alot about cars and performance! But you have to face it you dont have the insight knowledge of the Lancer. If you have to go out and buy one to find out the same thing were telling you then fine. Now, most of us are looking for reliable horsepower!!! Ive know tuners that get a car to make a ton of horsepower and break within a couple of weeks. Road Race Motorsports has done alot of research and testing and pushed the limit of this motor. On stock and aftermarket internals. There are also several guys on here that have learned the hard way. Thanks for the insight but i think most of the guys on here will stick with the guys that have actually tested the Lancer. I understand you are trying to help out and Thanks!!

 

Thanks Go2fast. Youre right, I dont know your guys engine but I do know that there have been instances in the past where it was thought that a paticular engine could only handle so much power and then it turned out that it could take alot more. It happened on my forum and it happened on the tiburon forum. Im not saying your engines will definately take 400 hp Im just saying that they can probally take alot more than what everyone thinks.

Anyway, My inital reason for commenting was not to argue about your engines but say that 9psi gives a different power number on different turbos. Thats all..
