450+whp Evos on pump (93) chime in!
My build is coming along more and more everyday now and I wanted to hear some feedback from those with 450+whp Evos on pump gas. I see so many fully built Evos on here with 500+whp on pump gas last forever. I've also seen a few on here fully built with less whp blow up. Everyone knows even with a built motor something can always go wrong. So why push it? Is there a certain whp on pump gas for longevity on a built motor? And yes I know purpose and set ups of the motor and car will vary. You just see so many different opinions on here as far as horsepower limit on pump gas because its not always reliable. So I want everyone's opinion and experience to chime in! What do people think esepcially those with high miles on a fully built motor? My goal is only 450-500whp and 380-420wtq on pump gas. The car will mostly be a daily driver with the occasional trip to the track until she's paid off. After that I plan on racing it a lot more. Road race, autoX and etc. The majority of opinions I've received lately all have said stay under 500whp or something will just go wrong. So be as honest as possible and thanks for looking guys!

I've tuned many 450-500 and 500+ whp cars on 91 octane. Always 0 knock. It's all in the setup and tune.
I've seen 300 wheel cars blow up on an improper tune and/or setup.

I know there's a lot of factors including the tune so it'll be a tough question to answer. I'm just curious to people's experiences. I plan on doing my build right for sure too. Meaning swaintech and ceramic coating and etc to help with heat control..

I dyno'ed out at 466 WHP uncorrected, 446 WHP corrected on a Mustang Dyno, 34 PSI boost (DBB FP Black) on 93 octane.
Car's been together for about 10 months, and is running great. Just took it out tonight, it loves the cooler weather
I'd say on the stock framed turbo's pushing past 480 WHP on pump, might not be the best of ideas, built or not, the fuel just doesn't have enough to prevent detonation. If you want more than that, switch to a different fuel.
I plan to do a few more mods to my evo and then have it tuned on E85 and will be shooting for 600 WHP.

nightwalker: I am doing a bigger oil cooler and other things as well!
Binky: I'm glad you chimed in. I saw your build and dyno sheet on here. I actually got my last tune from Jaime at DynoTech Tuning and I liked it a lot. To be honest as a daily driver on pump gas I didn't see much point past 480whp (dynojet) to be worth it.. In NH we just dont have options for E-85 or any other race gas at the pumps right now :-/ Hence the thread.

And you never had any problems beyond typical boost leaks now and then and etc sharkbite? I'm just starting to get paranoid cause the last 2 fully build evos i saw had engine failure at 460whp or less..

I had problems like blowing up manifols at 50+psi , destoying turbos (6) of them, cracking transmissions in half, destroying clutchs, hmmmm I think that about it. I never ever had to take the head off my car or changing anything in the bottom end ever, since AMS built it for me They did a great job I have to give it to them I never blew the engine.

Tranny and clutch become maintenance like everything else with that much power after awhile lol. I guess I'll try to be as surgical as possible with my build in controlling iat temps and coming up with a great tunable setup..

its all about tune, driving style, and turbo selection. From my experience, its early tq that kills a motor. Its easier to tune for knock on 93, so just get a great tuner and tell him to have your tq come on a little more gradual. Please get a CAS shield if you dont have one. Those little small things can go a long way.
-You can have the perfect set up from the perfect tuner and it doesnt mean a thing if you drive it like you stole every time you sit in it.
