lots of talk about blown motors
ive been scanning through threads, and it seems like way too high of a number of people have blown their evo motor, and im looking to tune my car for 400WHP, but ive been feeling indifferent about it, because i cant afford a repair that extreme, does anyone have experiance with this power range, and is it pretty safe HP, or does it put you at high risk? thanks

Exactly. People don't realize that anytime you install power adders your taxing the motor more and more. Eventually somethings going to give. Also, a lot of guys beat the snot outa their cars. I do it to mine, I just have a motor that can handle it.

I think that a year ago there were less threads about blown motors, and more threads about "hey look, I just made seventy billion hp on my stock motor its a new record" and that might have lead to alot more people haphazardly bolting on everything they could afford to the stock engine.. I mean after all, if he can do it, why can't I? Right?
lol... right

well, im planning on a dyno tune from a well known place in my area(performance autowerks) so hopefully that will give me better odds of having a longer lasting car, and it isnt a high mile car either

Before you tune check into mellon tuning.....they are really good at what they do. They can get you great power gains with 93 octane and if you want it conservative just tell them. they have have the fastest evo with 93 oct. and stock ecu/mass air. getting my car tuned right now with them, i have a GT35r kit.

to the OP what state do you live in? I know an amazing tuner in the MD, VA, PA area. Tampa racing in FL also has flown him down to tune i believe. Hes tuned several dsm's and evos to include a 1017whp talon. Brad Brooks. You cant go wrong with him.

With a low mileage motor and competent tune, you're probably safe for at least 60-70k miles with proper care.

[QUOTE=Ted B;7846468]Boasting how much power one makes with a factory shortblock is like a skydiver boasting how close to the ground he waits before opening the chute. Sooner or later there's a smackdown coming, and it's going to be messy when it arrives.
Haha I like that and agree 100%

Consider 350-400 a safe limit on the stock block. On a good tune you should be able to easily do 100,000 miles with 350+whp as long as you take care of your car. There is always the random engine that was built on a Friday at 4:30 and can't take the pressure, nothing you can do about that.
It seems most blown engine threads I've seen on here have been 350whp and above.
Isn't the FQ400/360/320 the identical block? They run that from the factory at close to 400whp so you'd think it would be a reasonable safe limit as long as your tune is semi-conservative.

Been making 500+whp/400wtq the last 2 years/30k miles now at 90k. I only get on it a few times each time I drive it (once a week) so no hot lapping or beating it to hell.
It has been through at least 400 passes down the 1/4 mile over the three years I raced it (only the last 100 or so being at 500whp level), 5 or so auto x events and 2 hill climb events (11 passes) going uphill for 2 miles straight full throttle, overheating on a few of the passes (too much boost).
So far I have had to rebuild the clutch twice, rebuild the tranny/xfer case once, and just recently milled my head due to the overheating warping it. Just tested it and it's still pushing over 500whp though. All this is on E85.
I know it is just a matter of time until something more serious fails, but it has gone 5 and a half years and 90k miles, 50k being over 400whp and the last 30k over 500whp. This has always been on a gt3582r though since about 12k miles. I got my kit when AMS was first putting them out. I think the larger turbo is part of the reason my engine is still in one piece, unlike a lot of the smaller turboed guys trying to push them for all their worth. My torque curve comes on a lot later in the rpm range and I don't really start ramping up timing until 6500rpm.
When I build my new engine I think I will either stay stock dimensions or go with the long rod.
