Whats the highest HP an MSP can reach on the stock turbos? With every other necessary modification. Just wondering... also if someone could tally up the total bill that would be nice. Just want to see my options.

I think JOEP back in early 03 hit around 275ish at the wheels with just a k&n drop in, a 3'' crush bend, and his own mbc set to 16PSI.
He actually ran the car up to 21PSI on race fuel.
The turbo's sweet spot is around 15-16PSI allthough Discreet did have luck running it at 18PSI for about a year with some paint thinnner mixed in the tank.
Neither one blew the engine but Discreet did burn a ring after a year.

blkzoomzoom hit like 800 hp lol, or so said the dyno when they blew his car up

you have to use xylene.

Some of the chemicals in paint thinner are high in octane. Or you can get race fuel but it's not as easily available to everyone as paint thiner is.

Xylene, to my knowledge, has chemicals or is the chemical itself in gasoline. By itself it has a high octane rating (over 100 from what I remember), so it is actually pretty safe to mix into your fuel to increase the octane. Toulene(sp) is also another product you can get from a paint store that does the same thing.

and what's the formula to mix it?
say i have 1/4 gas tank...how much would i mix??

isn't it the same as those octane boosters they sell??

The T-25 Runs Out at 15 Psi... At that point it's blowing so Hot that you might actually not see the diference between 13 and 15 Psi due to the losses and heatsoak.

Could this be weather dependent? It has been pretty cool here recently, around 55-60F and I upped to boost to 15-16. Air temps never went past 27C (didn't do any long runs really), normally my temps are 36-40+C on a normal summer day with lower boost.

I figure if it's cool out and your intercooler is doing it's job, might allow for some more boost on the T25 without losing performance.

I'll probably turn it up a little more if my injectors can handle it, just to see what happens with air temps.

As a rule, no.. If you look at the Compressor Map I posted, the GT-25 is way out of room at anything over 15 Psi...

No matter how good your FMIC is, it is still spinning over 125,000 RPM and will fail shortly.

Question about those maps. How do we know what kind of air flow we are getting? Because actually, if you look at the map, 15 psi at just under 25 lbs/min airflow is at the edge of the GT25's peak efficiency.

I guess the only part of the compressor maps that I don't understand are where we get the lbs/min value.

Are the blue dots on the map points of reference for our engine?

The Blue dots are a Pressure vs. Flow that a 2.0 L motor uses at Redline.

OMG It's the magic Cannuck with a picture (first)
This is why my has been gutted, ported, polished and had new wheels installed. :)
Lots mo power to be had.

Obligatory on topic comment: 15-16PSI stock turbo blah.

so you guys do know that the map there of the GT25R is different than the stock MSP T25R right? teh different turbo boyo ;)

and fyi, anyone who thinks 15psi is the max, ive driven my buddies non BB T25 in his Talon and 20psi is the shit. makes 15 seem slow, no FMIC. You get like 5whp for each psi after 15 but it works lol id stay at like 16-18psi. just make sure you have fuel control and a shit load of that xlene stuff

and to answer the question of the thread starter, the MSP turbo can flow ~300HP depending on your setup, gas, EMS and how long you want the motor/turbo to last. a tuned 18psi with methenol injection and all supporting mods would kick some serious asss.

yashooa how much psi are you running on the upgraded turbo, and what's the max that it can handle. also did you switch out the wastegate when you upgraded it
