full potential of the stock motor...

I was just wondering how much power our engines can hold with stock boost (stock turbo) just basically all possible bolt on modifications? what could be the max hp/tq?
 
Doesn't gets challenging for a FWD car with traction over 300whp? I'm speaking about a DD though.
 
I cracked a piston at 317whp with a dyno'd professional tune. The only guy in the us that can tune these is like 40 miles away is all :) but anywho runnin untuned i wouldn't push my luck to 350
 
What I meant was that over 300whp could be too much power for a fwd car. Because of how hard it is with these cars wheels to find traction. Capish lol.

Man, 350 RWHP would be about 400 at the crank. Is that possible without some work on the internals?

You did 317whp on a Mustang Dyno. On a dynojet, you'd probably see higher numbers. On a dynapack, probably a little less.

My dyno guy can tune these cars pretty well too! I bet my dyno guy can beat up your dyno guy! hahahaha
 
haha His dyno guy is Tim Baily at surgeline..and hes only 1 half drive from me. Hes one of the best ms3 tuners in north america. Anyways..its hard to say max power..I alwas hear 350 alot..but then you hear of people blowing rods when they have just a intake or bov mod..so who knows..I honestly wouldnt go over 300 whp in these cars with stock block as a dd..I think 280-300 is prabaly about perfect.. Its already got plenty enough hp and tq for a fwd dd. If you want way more power go evo or sti and build that up..or go muscle car..these ms3 engines are some picky ass mofo's...some will go thousands and thousands of miles modded..and some will bust a rod or crack a piston bone stock at 10000 miles..and the car ecu is tricky too as the ots maps seem to vary from car to car..which is way different than with the suby's...these are great cars..nice interiors fast enough for most people..decent on gas when you not putting your foot into it..but just becareful..id say its apretty stable study platform..but wouldnt press my luck..when i get my custom tune from surgeline..its gonna be anice conservative one....I plan to keep my car for while..and really dont wanna join the zoom zoom boom club..I mean dont get me wrong..going forge engine is sweet...but at the time I really dont have thousands of dollars hiding in a cookie jar for that..so I just enjoy my car and extra boost and dont push it too far..as for 350-400 hp on a fwd platform..well hell yes its gonna cause torque steer and traction issues are gonna suck alot more..your talking about strong motormounts and beefing up the bracing and running some super sticky wide tires..bottom line I dont know s*** about cars compared to some people in here who are extremly inteligent about subjects like these..But i think 300 whp is pretty much the farthest you wanna go on stock block dd..can you go more? yep..I just wouldnt..maybe im a pussy idont know..but idont think this engine is made to be a madman stock..thats why you go forge or buy another car...my 2 cents

true. but what im saying is that if i were to just add a full tbe, turbo manifold, plugs, an AP to tune and anything other bolt on power mods, would that be to much for the car. I dont want to touch the boost with any controller and i dont want to get a different turbo. Basically im freeing up as much as possible.
 
Okies..... I would keep things simple.... I wouldnt get the turbo manifold..makes great power but think it works that stock turbo alittle too much..so would go with a tuning solution from either cobb or cpe..then I would get a intake..sri or cai..up to you...then free up the exhaust..with a downpipe of your choosing..turboxs,corksport,cobbtuning,stainless works,cpe..some have cats some dont. then get a fmic from PG. in terms of power mods that should be good for 300 whp and thats plenty and safe for bolt on power...ofcourse theres suspention mods and drivetrain mods for whatever suits your budget and driving style..but in terms of power-intake,dp,pg fmic and tune would make your ms3 a breast.

the ap ots maps all up boost...
 
OP its hard to say the full potential of the stock motor. some of it is how you build it/tune it and drive it for sure, but many of them blow at part throttle because these cars run lean with so much timing in closed loop... some stock, some with only an intake/exhaust blow up. I wouldnt go past 330whp or so with it.

how much power you puttin down man? i ask cause you have basically the same exact mods as im gonna be bolting on aside from my tbe so im interested..

well then if i where not to get the AP and not tune it.. just have the tbe, fmic, and turbo manifold.. would that be to much. would that be near 330whp? with all the bolt ons i have now.?
