Has anyone found the limits on this motor yet?
Max hp and max tq?

For a complete stock block i have heard so many rumors before but has anyone busted the myth?

 

I would bet yours was right on the border of limits at 17psi. But we also know every motor is different. Especially since nobody has any one scenario the same. How well the car was maintained by a previous owner(s) could be the biggest in my opinion. I know I've been pushing 11 and spiking at times to 13 for 6 months now and going strong, things seem to good so far. And I'm still on the stock head bolts as well.

 

You can't just throw PSI numbers around in general and say thats the max, how do you know what turbo they are using? Different turbos will produce different outputs at a given pressure.

Power will also depend on the fuel and the knowledge of the tuner.

 

Gotta say your right. But also goes to every car is different. Setup and Tune are huge factors as well

 

well you definetly know how I tune with my previous thread, I was very specific on how I wanted my afrs and how they affect my power ratio of hpvs torque

 

I dont think you will find an answer for this. None of us want to blow up a motor. Besides whats to say 17lbs isn't reliable for 100k vs 20lbs being reliable for say 10k. Hard to really say since our cars weren't designed to have a turbo to begin with. I think 15-17 is a good satisfying number.

 

been turbo since 80k i think 2 years? but sitting at 17psi and compression is still at 210 each cylinder at 112,000 miles. turbo has at least 90k on it. 16G. I think im done trying to go any further. no point when you cant get traction until 3 gear. even then still chirpin new tires.

 

yea I guess your right, then its settled we found our number lol case closed

 

Depends. RRM used to recommend new pistons and rods at way less than 17 PSI. I think they said the limit was around 11 PSI on a T28 or 16G.

 

That's because they wanted you to buy their over priced stuff. At the time you didn't have anyone else to turn to for those things.

 

But that was back then when we didnt have ecuflash and tephra v7.

Whats scary is their piggyback units that they use for their turbo kits only control fuel and not timing.
When I finally removed that POS piggyback and switched to ECUflash,
my tuner said it knocked less without the piggyback on OEM maps

 

back to the origonal post..

ok. when u said complete stock block..

the numbers are NOT up the air.
Most everyones motors tend to start failing just beyond 200-220hp/200-220tq.
Generally.. 240trq is considered the limits are rods can handle, also the limit to the auto trannys also (if ur an auto). anything beyond that is just dumb luck that u havent launched a rod out the side or you really just dont ever get on it.. but i know when i go to the track i go there to dog my car hard...

This is a slight BASH on most all the DIY tuners. but.. boost is irrelavent without hard proof dyno numbers.. so if someone says 9psi or 12psi or 17psi is max.. that means nothing. has nothing to do with size of turbo u use, how ur tuned, or what fuel ur on. or even how much power ur making. (on a bad tune u could be making same power at every boost level depending on ur fuel/timing)

4 motors later. I learned my lesson.

would be nice to know what they got with the lancer on the cover

... never mind seems its an evo with a lancer front end?

link. pretty sure that is a 01 lancer/evo. that was never released. and was only used for racing applications and made way for the base lancers

as u know. the body/chassi is basically identical from an evo and a lancer. aside from bumpers/lights and drivetrain components
more then likyly the car is an 01 platform like mitsu used for all ther rally events..
There easy to spot.. Headlights and taillights are same as a lancers.


Same as this one. (was the mitsu awd platform for 5years? this one and the evo7 were both used at the same time depending on which event it was)

what turbo are you running and how much did it cost to buy and was it a easy or difficult install?
